They did nothing of the sort. You can use 2 terminal service licenses for remote administration in 2k just like 2k3. They are absolutely *not* free in 2000.
For regular users, not remote administration, you are supposed to get TS licenses; be it win2k or win2k3. Don't take my word for it.
Q. Do I need to purchase a Terminal Services CAL for each machine that is running a validly licensed copy of Windows XP Home Edition and connected to a Windows 2000 Terminal Server?
A.
Yes, all Microsoft operating system products (except for Windows 2000 Professional and Windows XP Professional) require a Terminal Services CAL to access a Windows 2000 Terminal Server.
I bought my dual GPU 3DFx Voodoo5 around this time 4 years ago. . . and then the company was bought, support disappeared, and my fancy video card became worthless even quicker than it should have . . . I don't recollect seeing another 'dual gpu video card that will slay the market' announcement since . . .
If this is an EOL system and its using U160 drives ..chance are those drives are 36 gig or less ..I'd even bet they might be 18's . . . But lets say they are 36's . . four of them in a raid 5 is giving you ~120GB? Why not just get a pair of 147GB drives and run in a raid1? I mean, like others have said, without knowing what you are doing with it, it is hard to say where you are going to get the most benefit, but a lot of times, Raid5 is chosen just due to the increase in space you can get. . . There are more complex options out there that can get you better performance than raid5 (ie, raid 1+0 raid 5+0 and similar) if your controller and wallet support it . . .
What about using a directional antenna? The cantenna might get your signal over there better . . . Unfortunately, it doesn't appear to be sold with cookies anymore . . . You could also try one of the pringle can DYI antennas and see if it helps?
Whenever I use electrical tape, it eventually peels off since it's only a little piece. That and it leaves a pretty gummy residue that takes a bit of goo gone to remove.
I actually have started using velcro tape pieces. It doesn't show as much since its not reflective and just leaves a little fuzzy divot and when I've peeled it off after a year, it didn't leave any residue (it more just popped off like rubber feet do that are on a device for a long time).
For that matter, spare rubber feet work pretty well too and usually don't leave residue (though I think they stand out a bit more).
It looks nifty, but its not a sniper rifle

I've put something similar in place which utilized the built in NTBackup as well as a combination of SSH/FTP. Scripting out NTBackup is easy enough; you just create the BKS file it'll use, backup using that file, and then get the file over to your linux system.
To backup the systemstate (you need to do this on your DC's and Exchange boxes), you have to do it locally.
Instead of putting in a directory in your BKS, just put the word: SystemState on its own line.
Your exchange directory store: DS \\EXCHANGESERVERNAME
You exchange information store: IS \\EXCHANGESERVERNAME
Directories and files: c:\whereever\blah\blah\blah c:\anotherdir \blah
To exclude: add a/exclude to the dir/file line in the BKS.
Note: The BKS files are in a sort of unicode format (thanks Microsoft). I was using perl to create the files before every backup so I didn't have to depend on changing static files on each system being backed up. Its not quite unicode . . . open the file in a hex editor and check it out if you want to write them dynamically.
To kick off ntbackup at the commandline and use that BKS, something like this would work:
Or for an incremental: ntbackup backup "@\\server\backupdir\YOURSERVER_bunchadirs.bks"/j "Helpful Description BunchaDirs"/f \\server\backupdir\name_of_your_backup.bkf/n "Helpful Description BunchaDirs"/d "Helpful Description BunchaDirs"/v:no/r:no/l:s/a/m incremental/rs:no/hc:off
I was planning on exclusively using SCP to transfer the files between the systems, but I ran into problems with the Win32 SSH client and server. Anytime I wanted to move a file bigger than 2G off the Win systems, I'd end up with a corrupt file. (So, I had to resort to using FTP in some cases).
Only semi related, If you are backing up systems at a datacenter and eventually sending them to a repository in the office (or vice versa) and sending them over a limited data line (we only had a couple T1's), you might want to look at the shaper app. I was able to limit the traffic heading over that T1 line after it was conglomerated on a datacenter server so that the users in the office could still do their work.
After adding a few hooks to the various scripts to have it spew its progress to a central server that I monitor for errors, I had a fairly scalable script based backup system using built in backups (NTBackup on 2k/Xp/2k3 and Tar). Oh, and Bzip2 is your friend on the windows systems. Getting around 2GB file size limitations was the biggest pain in the whole setup. Go through some good QA and check every backup that is created for the first week; it sucks finding out your files are corrupted when you need them . . .
Now, if you drop, say, 2000 server on a 4 proc HT enabled system, it's silly since it'll count the first 4 logical against the inherent processor limit so there isn't any reason to turn HT on . . . But they don't charge you *more* for licensing on a HT enabled system per logical processor. Similarly, using a dual P4 xeon with HT enabled on a Windows Xp professional install is silly for the same reasons. But you don't get charged more for turning on HT on a single proc XP pro system. It shows as two procs, you pay for one physical.
I suggest you review the following which details their licensing when it comes to HT.
For those that don't want to RTF-MSWordDoc, the pertinent line:
Windows Server licensing is based on the number of physical processors on a system
SQL Server is the same way. Physical procs count (and SQL server *can* tell the difference between logical/physical and spreads the workload across the physicals evenly rather than loading up logicals per processor disparately).
Which product did you find that they claim they are charging for logical processors?
They say they can tell the difference between the logical and real processors (and I'm tempted to believe them since SQL2kSp3 does seem to handle the load distribution across the physical procs gracefully). They've got enough monkeys at enough keyboards that I'd wager they will be able to tell the difference . . . and as pointed out by the A/C above HT *is* different since they are logical procs, but if they keep the same stance and continue using the term 'Physical Processor', they might keep the licensing for the multi-cores to be associated to the number of chips going into sockets . . . I can dream anyways. I tried finding an article mentioning their stance on multi-core CPU's and failed . . . I'd definitely like to see it if someone can find it.
A recent example would be the Hyperthreaded CPUs. SQL Server can be licensed per CPU and with Hyperthreading, the software does for all intents and purposes treat it as a second CPU. However, Microsoft's stance is surprisingly that you only license per the physical processor.

I saw this post and thought "Hey! I could use one of these" and a 6 post mini din with a 10k resistor is less than 3 bucks.
I stopped by Frys on the way home and picked up a baggy of 10k's and a pair of 6 pin mini dins and gave it a shot. I made two of them (just in case I flubbed the soldering in my excitement for cheap keyboard fakers). Neither one worked on systems that I turned on the 'halt on all errors' option in the bios. I tried turning off the 'turn on numlock on boot' options and this didn't make a difference. It looks like the systems are a little smarter than all that. The packet came with 4 resistors in it so I'll probably stop by again tomorrow and try this with an AT connector hooked to a ps2-AT converter and see how it goes.
Would have been nice if it worked though . . . If anyone has confirmed this to work (and proving once and for all that Stevie Wonder could do a better job at soldering than me) please post!
A problem I enjoy pulling out to play with now and then is doing a usable data set that can do reverse IP lookup to geographic location . . . there are services that offer it, but there isn't any reason you couldn't write stuff to do this yourself.
Big data sets with a lot of the information being available through publicly queryable sources.
There are lots of approaches to mapping it all out (start with class A, then to B, and onward or you can start with specific ranges . ..). Between whois info, dns, and trace routes alone you can have some fun doing the mappings . ..and in the end, you have a useful and marketable dataset that you created . . . IP -> Geography is valuable. Once you've got the data though, there's even more . ..how do you manage data sets that large? You can't just throw every IP into a single table . ..not unless you are the index king . . .
I don't know of a ready made data set of this nature, but putting the data together into the dataset and loading it is gonna teach you as much about the languages you are using to load it as it will about the data and managing it via sql services. . .
I would hope that if you are working with a TB of data, the value of that data is pretty high . . .
Promise SX6000 = $255.95.
(6) 200GB IDE drives in a Raid 5 = $624.95
If you had a separate boot drive from the SX6000, you could just bring the system down for a couple hour maintenance once a month and slam all the drives out and put fresh ones in.
Just keep buying new 200GB drives anymore and shelf the old ones (or if its *really* valuable and your home firesafe isn't enough, pay Iron mountain or someone to keep it).
There aren't hidden labor costs outside of those two hours it takes to setup a new array every month (DVD's are about 60 bucks a month for a TB, with a hundred or so for a drive (which *will* need to be replaced occasionally if you are burning that much) but you'll spend hours and hours just dealing with the swap outs and breaking up your data ... )
If you don't have to keep the TB of data after a month or three, then your price gets even cheaper after you invest in your initial hard drive media sets . . . and you can put all the drives in hot swap chassis to further minimize your time dealing with the issue.
Of course this is all moot if your 1TB of data isn't valuable enough to invest 600 a month in . . .
With all the 'strategy firms' making outlandish claims lately regarding IT individuals needing to have fear of being replaced by a machine (that is gonna be maintained and admin'd by who again?) . . . it makes me wonder if its just some IT nerd hatred bubbling up . . . Maybe these 'strategy' firms have a lot of employees that were tired of having their grading curves blown when they took a 'real' class back in school . . .
Maybe an open source project should be started oriented around automating strategy analysis for companies . . . I would wager it'd be easier to program that type of intelligence than the kind they are predicting . . .
Oh who am I kidding . . . StrategySoft will just eventually predict that the coders who made it aren't going to be needed and others AI like StrategySoft will be able to build StrategySoft2.0. And at some point Arnold Schwarzenegger (or if I'm lucky Kristanna Loken) comes back to kill me and anyone who ends up reading this . ..
Seriously though, who are these guys that they feel they can make this type of prediction? Glancing through their webpages, they list automotive knowledge, home broadband and wireless type knowledge and other bits that are related. I didn't really see much in there about internal IT infrastructure stuff?
This is a very true statement. I only make it 'home' every couple years now. The last was for one of my old high school reunion. I was only going to be around the house for 4 days after the reunion 2 hours away. My father was supposed to be there for the last two days. His pickup was delayed. -12 hours. He is limited to 8 hours a day. minus a few more hours. His drop off was delayed. He waited 12 hours. He hightails it home. And misses me by 2 hours since I had to leave amongst hurricane evac traffic and needed an extra hour to get to the airport to get out. (gotta love the carolinas in the fall . ..)
Truck drivers don't want to spend time at rest stops. When they are resting, they are doing just that; resting. But, with limitations on how much they can drive in a given day and over a given week, there is time where they have to do something. Cell phones are getting cheaper, especially with family to family calling, but there are always limits and rules that eventually bring that bill up.
Getting connectivity during one of those stops would allow him to IM with my mother and youngest brother. And if they do this in enough places (he doesn't often get down here to Texas that often), I'd be motivated to outfit his rig with some good wifi gear and try out some VOIP stuff (which might bomb, but its worth trying).
Military pensions for those who've faithfully and honorably served decades just doesn't go far enough. It's bad enough that my father has to work his retirement years away from his family. Any little thing that could improve that time he spends away being a part of the grand interstate commerce scheme and let him keep in touch I see as a good thing. Truck drivers aren't the scuzzy hollywood stereotype (though I'm sure there're some that are, I haven't met any yet) . . . Many are ex-military. And most know how to use a computer since most of those semis are equipped with Sat driven comptuers to monitor their locations and times spent driving now . . . it's just too bad those don't allow for data uplinks for them to hookup pc's into or supply a voip connection.
Get a Paladin Toner and Probe (somewhere around $80) or something similar. Get your son/wife/trainedchimp to go through jacks plugging in the toner (cellphones help here; or just yell real loud) while you tone the cable to find which one is which.
Assuming you are putting these cables in a Patch panel you can just masking tape label them until you get them into their ports. Worst case is the tape comes off and you have to retone your wires (you didn't seem to have more than 30?). As for Making it look pretty just go with whatever cable management fits your budget and your mounting method. If it's in a basement and the stuff isn't gonna be bumped, you might as well go with an open relay rack bolted into your floor (you can hacksaw them down to size fairly easily since they are usually aluminum).
Supplied links are my personal hardware preferences . . .
A year or so ago, setting up a PXE linux based system took a little bit of effort, but today? It's cake. Check this out. Its a simple to setup PXE environment. The documentation is fantastic and it 'just works'. You can setup a simple browser only xwindows type environment or do what I prefer to avoid weird windows issues: Setup a Windows terminal server and use Rdesktop in that pxe environment to give everyone a real microsoft desktop. I had difficult making the sound pipe down to the local machine but . ..who needs that anyways? With the money you save on replacing those hard drives buy that staff IPod's (and two or three for yourself) (though getting stuff on the ipods with those pxe boots might be challenging).
The things that fail most often are things that move . . . it is absolutely possible to eliminate every fan and drive with this type of environment. Ram fails, but its a whole lot less often that the drives . ..and so what if it does?
"What? Your system is just beeping. Oh. Well just use this system which I have magically moved all your stuff to already"
MySQL has changed their licensing recently and they are very restrictive about which OSI Approved licenses are acceptable for use with their product (without paying the licensing fee). If it's not GPL, you are likely going to have issues. They have a very short list of what does and does not qualify. However, they are responsive when you write them at licensing@mysql.com (albeit it took several days) when you need clarification.
Apparently PostFix's OSI Approved IBM Public License does not qualify so I'm having to prep to pay for licensing since we use postfix with MySQL (confirmed with their licensing folks). They did assert that they were still in the process of reviewing other licenses.
Raided motion detectors? How'd they do it with just one though? Did they go with a motion detector mirror or were they looking for more of n-1 most motion detection for their buck type setup with a motion detector 5? Huh? Made up story about the usaf raiding civilian homes? Oh. Never mind.
It doesn't say breaking down after 100k emails a day. Everyone here knows most mail servers can do that on junk hardware in a day(yes, Even exchange can do it).
It sounds more like they are having problems when they start reaching 100k messages in the queue. Anyone who's dealt with tracking a large number of small files across a file system knows that there can be slow downs (not that there aren't solutions to those, but they may not have been able to spend the time to address the problem since they've been 'fighting fires'). When my incoming postfix/amavis/spamassassin systems get 100k or so mails in their queues on ext3 file systems, they start behaving badly too. We addressed the 'fire' problem by throwing more front end servers at it while we take time to rethink our file systems where the queues reside. We'll get the the luxury of a few weeks to address it with other hardware before we start getting unacceptable delivery delays again (for us, thats Universities don't always have the money to throw hardware at a problem like this or are willing to give their often student supported IT administration the benefit of the doubt that 'we need $20k (euros, lira, beads, whatever) to buy some hardware to roll a better solution'.
Yes, I'd be surprised too if they mean '100k emails a day and we bog down' . . . I just seriously doubt that is what they mean. Maybe they are stopping their spam/virus processing just to clear their backlog. Maybe its not that they aren't receiving it & spam processing it fast enough; maybe its their backend server that is taking it all in just can't keep up. I mean, if they've got 20 spam/virus receivers that are getting the job done and trying to hand off to one fat exchange box that isn't keeping up then their queues are going to grow on those front ends and eventually kill them which makes it look like their spam/virus scanners are causing the delays.
Then again, they could be a bunch of retards and everyone is right that they don't know how to run even a low volume mail server . . . but somehow I doubt it . . .
We use multiple front end postfix systems with the amavis-spamassassin-clam combo to hand off to a backend Imail server (which could be any backend mail server really), servicing several thousand domains and tens of thousands of end users in those domains. With the auto-updating features setup to check in hourly, we usually have the definitions for the latest worm on the system before it really starts hitting critical mass. When the Mydoom worm (worm.sco.x) came out, the definitions on our servers were updated on the 25th of January, the worm seemed to really start pounding things on the 26th and 27th. Monday morning, it had blocked 10k+ of the little bandit before any had gotten through and I got to read about the unhappy griping of the Norton AV users who hadn't gotten updated in time. It was a case where if we'd used anything but clam, we'd probably have had to deal with plenty of whiney end users (and who wants that?). Now, I'm still not 100% sold on clam, I'll sing its praises, but I'm not going to just use it just yet (so it takes me 6-12 months for me to trust something, call me paranoid). On the actual back end mail server, I'm still using declude to tie into f-prot's scanner. However, since setting up clam, I don't think there's been a single virus that's made it through (going on 5 months now) for it to catch. As Martha would say, "It's a good thing".
With the recent bagle and somefool worms, I was seeing lots of catches by amavis-clam, but it didn't handle the encrypted zips correctly (though word on the mailing lists are there are mods/updates that can be made to start handling them right. I'm just gonna dump all zips for now, those pesky users dont deserve 'em anyways). To answer the original question though? Is Clam ready for primetime? I think so, but erring on the side of caution and having another layer of virus checks in there can't hurt . . . either way, you'll need to keep tabs on it for the next 'catch you by surprise' variant that even the commercial products aren't responding to in time; the more users you are supporting, the higher the probability that you are going to be the one dealing with an account that was one of the first to receive the newest worm . . .

When they say it is limited to one proc, do virtuals count (ie, P4 HT?)
.
.
I've never looked at Sybase and have no clue how it works; especially their licensing . .
I'm assuming if I have a true multiproc system, it's only going to utilize one physical proc . .
Anyone have the dirt, I couldn't find a detailed link on the limitations other than the single blurb that was in the original post.
If only this was around for a certain Australian beauty queens strut down the catwalk last week. *sigh* Pan Baby!

.Net setup to distinguish between the two and only count physicals against the processor limits

If you don't have to keep the TB of data after a month or three, then your price gets even cheaper after you invest in your initial hard drive media sets . . . and you can put all the drives in hot swap chassis to further minimize your time dealing with the issue.
Of course this is all moot if your 1TB of data isn't valuable enough to invest 600 a month in . . .
With all the 'strategy firms' making outlandish claims lately regarding IT individuals needing to have fear of being replaced by a machine (that is gonna be maintained and admin'd by who again?) . . . it makes me wonder if its just some IT nerd hatred bubbling up . . . Maybe these 'strategy' firms have a lot of employees that were tired of having their grading curves blown when they took a 'real' class back in school . . .
.
Maybe an open source project should be started oriented around automating strategy analysis for companies . . . I would wager it'd be easier to program that type of intelligence than the kind they are predicting . . .
Oh who am I kidding . . . StrategySoft will just eventually predict that the coders who made it aren't going to be needed and others AI like StrategySoft will be able to build StrategySoft2.0. And at some point Arnold Schwarzenegger (or if I'm lucky Kristanna Loken) comes back to kill me and anyone who ends up reading this . .
Seriously though, who are these guys that they feel they can make this type of prediction? Glancing through their webpages, they list automotive knowledge, home broadband and wireless type knowledge and other bits that are related. I didn't really see much in there about internal IT infrastructure stuff?
This is a very true statement. I only make it 'home' every couple years now. The last was for one of my old high school reunion. I was only going to be around the house for 4 days after the reunion 2 hours away. My father was supposed to be there for the last two days. His pickup was delayed. -12 hours. He is limited to 8 hours a day. minus a few more hours. His drop off was delayed. He waited 12 hours. He hightails it home. And misses me by 2 hours since I had to leave amongst hurricane evac traffic and needed an extra hour to get to the airport to get out. (gotta love the carolinas in the fall . . .)
Truck drivers don't want to spend time at rest stops. When they are resting, they are doing just that; resting. But, with limitations on how much they can drive in a given day and over a given week, there is time where they have to do something. Cell phones are getting cheaper, especially with family to family calling, but there are always limits and rules that eventually bring that bill up.
Getting connectivity during one of those stops would allow him to IM with my mother and youngest brother. And if they do this in enough places (he doesn't often get down here to Texas that often), I'd be motivated to outfit his rig with some good wifi gear and try out some VOIP stuff (which might bomb, but its worth trying).
Military pensions for those who've faithfully and honorably served decades just doesn't go far enough. It's bad enough that my father has to work his retirement years away from his family. Any little thing that could improve that time he spends away being a part of the grand interstate commerce scheme and let him keep in touch I see as a good thing. Truck drivers aren't the scuzzy hollywood stereotype (though I'm sure there're some that are, I haven't met any yet) . . . Many are ex-military. And most know how to use a computer since most of those semis are equipped with Sat driven comptuers to monitor their locations and times spent driving now . . . it's just too bad those don't allow for data uplinks for them to hookup pc's into or supply a voip connection.
Get a Paladin Toner and Probe (somewhere around $80) or something similar. Get your son/wife/trainedchimp to go through jacks plugging in the toner (cellphones help here; or just yell real loud) while you tone the cable to find which one is which.
Assuming you are putting these cables in a Patch panel you can just masking tape label them until you get them into their ports. Worst case is the tape comes off and you have to retone your wires (you didn't seem to have more than 30?). As for Making it look pretty just go with whatever cable management fits your budget and your mounting method. If it's in a basement and the stuff isn't gonna be bumped, you might as well go with an open relay rack bolted into your floor (you can hacksaw them down to size fairly easily since they are usually aluminum).

A year or so ago, setting up a PXE linux based system took a little bit of effort, but today? It's cake. Check this out. Its a simple to setup PXE environment. The documentation is fantastic and it 'just works'. You can setup a simple browser only xwindows type environment or do what I prefer to avoid weird windows issues: Setup a Windows terminal server and use Rdesktop in that pxe environment to give everyone a real microsoft desktop. I had difficult making the sound pipe down to the local machine but . . .who needs that anyways? With the money you save on replacing those hard drives buy that staff IPod's (and two or three for yourself) (though getting stuff on the ipods with those pxe boots might be challenging).
.and so what if it does?
The things that fail most often are things that move . . . it is absolutely possible to eliminate every fan and drive with this type of environment. Ram fails, but its a whole lot less often that the drives . .
"What? Your system is just beeping. Oh. Well just use this system which I have magically moved all your stuff to already"
MySQL has changed their licensing recently and they are very restrictive about which OSI Approved licenses are acceptable for use with their product (without paying the licensing fee). If it's not GPL, you are likely going to have issues. They have a very short list of what does and does not qualify. However, they are responsive when you write them at licensing@mysql.com (albeit it took several days) when you need clarification.
Apparently PostFix's OSI Approved IBM Public License does not qualify so I'm having to prep to pay for licensing since we use postfix with MySQL (confirmed with their licensing folks). They did assert that they were still in the process of reviewing other licenses.
Raided motion detectors? How'd they do it with just one though? Did they go with a motion detector mirror or were they looking for more of n-1 most motion detection for their buck type setup with a motion detector 5?
Huh? Made up story about the usaf raiding civilian homes? Oh. Never mind.
It doesn't say breaking down after 100k emails a day. Everyone here knows most mail servers can do that on junk hardware in a day(yes, Even exchange can do it).
It sounds more like they are having problems when they start reaching 100k messages in the queue. Anyone who's dealt with tracking a large number of small files across a file system knows that there can be slow downs (not that there aren't solutions to those, but they may not have been able to spend the time to address the problem since they've been 'fighting fires'). When my incoming postfix/amavis/spamassassin systems get 100k or so mails in their queues on ext3 file systems, they start behaving badly too. We addressed the 'fire' problem by throwing more front end servers at it while we take time to rethink our file systems where the queues reside. We'll get the the luxury of a few weeks to address it with other hardware before we start getting unacceptable delivery delays again (for us, thats
Universities don't always have the money to throw hardware at a problem like this or are willing to give their often student supported IT administration the benefit of the doubt that 'we need $20k (euros, lira, beads, whatever) to buy some hardware to roll a better solution'.
Yes, I'd be surprised too if they mean '100k emails a day and we bog down' . . . I just seriously doubt that is what they mean. Maybe they are stopping their spam/virus processing just to clear their backlog. Maybe its not that they aren't receiving it & spam processing it fast enough; maybe its their backend server that is taking it all in just can't keep up. I mean, if they've got 20 spam/virus receivers that are getting the job done and trying to hand off to one fat exchange box that isn't keeping up then their queues are going to grow on those front ends and eventually kill them which makes it look like their spam/virus scanners are causing the delays.
Then again, they could be a bunch of retards and everyone is right that they don't know how to run even a low volume mail server . . . but somehow I doubt it . . .
We use multiple front end postfix systems with the amavis-spamassassin-clam combo to hand off to a backend Imail server (which could be any backend mail server really), servicing several thousand domains and tens of thousands of end users in those domains. With the auto-updating features setup to check in hourly, we usually have the definitions for the latest worm on the system before it really starts hitting critical mass. When the Mydoom worm (worm.sco.x) came out, the definitions on our servers were updated on the 25th of January, the worm seemed to really start pounding things on the 26th and 27th. Monday morning, it had blocked 10k+ of the little bandit before any had gotten through and I got to read about the unhappy griping of the Norton AV users who hadn't gotten updated in time. It was a case where if we'd used anything but clam, we'd probably have had to deal with plenty of whiney end users (and who wants that?). Now, I'm still not 100% sold on clam, I'll sing its praises, but I'm not going to just use it just yet (so it takes me 6-12 months for me to trust something, call me paranoid). On the actual back end mail server, I'm still using declude to tie into f-prot's scanner. However, since setting up clam, I don't think there's been a single virus that's made it through (going on 5 months now) for it to catch. As Martha would say, "It's a good thing".
With the recent bagle and somefool worms, I was seeing lots of catches by amavis-clam, but it didn't handle the encrypted zips correctly (though word on the mailing lists are there are mods/updates that can be made to start handling them right. I'm just gonna dump all zips for now, those pesky users dont deserve 'em anyways). To answer the original question though? Is Clam ready for primetime? I think so, but erring on the side of caution and having another layer of virus checks in there can't hurt . . . either way, you'll need to keep tabs on it for the next 'catch you by surprise' variant that even the commercial products aren't responding to in time; the more users you are supporting, the higher the probability that you are going to be the one dealing with an account that was one of the first to receive the newest worm . . .
