If you happen to live the the Puget Sound area then check out Boeing surplus in Renton. I found a mint condition cabinet with 3 shelves and huge power strip for $100. They always have 3 or 4 (nonmint) lying around.
Beware: cabinets are heavy. I had to carry (drag) mine up half a staircase and even with all the side panels off I nearly killed myself.
OpenSSH is slower than (closed) ssh

SSH vs SSL/Telnet
·
· Score: 1
For interactive sessions OpenSSH may be fine but it has about 1/3 the performance of ClosedSSH for bulk transfers, e.g., (r|s)cp, network backups.
I cannot agree with the Apache::Registry comment more. That way lies pure madness. If you don't know what a closure is or do not understand the intracies of perl's scoping rules then do not use Apache::Registry for more than your simplest application. Weird things happen. Your variables will take on values that mystify you. You will post lame questions to the modperl list about it.
mod_perl has so much more to offer than just Apache::Registry. Do not try to maintain CGI compatibility. Just bite the bullet and start writing mod_perl-specific scripts.
I'm doing my part to increase the visibility of Linux in the Seattle area: head over to The Eastside Journal. See Tux and Wilbur on the bottom right of the page? The Eastside Journal is a medium-sized paper serving the eastern part of King county (Seattle is in King county). It also serves Redmond, WA. Take a look at the page source for more grins. Bill Gates cannot escape Tux at home either: he lives on Mercer Island
If you need interoperability then you should get an external unit that connects to the pc via ethernet. Otherwise internal card + ISDN4Linux may work for you. Keep in mind the dispute between the ISDN4linux people and Linus. Also, since Germany seems to be primarily ISDN, check out the SuSE distro and any tools SuSE offers.
If you don't need options then a lowend 3COM OfficeConnect terminal adapter (I don't know why they call them modems) will work for you. My OfficeConnct only had a Winblows configuration utility. They seem to have a web interface now (How does it get its IP addr? Rarp, bootp, DHCP, eh?).
If you want features and configurability then get a Pipeline 75 ISDN router. It isn't for your typical FOR-DUMMIES reading computer user. You must be able to read and understand a manual and have a clue about networking (protocol stacks, RFCs, etc). It has lovely serial and telnet interfaces. (I'm sure there is luser gui interface for it by now.) I liked the Pipeline better than the 3COM.
You should find out what type of switch you will be connecting to and make sure the device you buy supports it. You probably want the device to support multilink ppp plus as well.
Don't worry: Seattle will loose some of its tourist appeal when terrorists blow up the Space Needle. If I were blowing it up, I would make it fall NWerly in the hope that it would crush as many people on Mercer St as possible.
Mon (from Jim Trocki at Transmeta) can do snmp and other types of monitoring. The architecture is simple and felxible. The configuration is getting a bit kludge-like though.
Do not use the cmu snmp package. It isn't being developed anymore and it sucks. ucd snmp is much still being maintained and is much easier to use when setting up process and filesystem snmp monitoring.
There are quite a few Microsoft zombies posting on/.. The common form of their posts is:
Linux rules. I really hate M$ myself and would never use it.
However, I run IIS on my NT machine. It takes 10^23 hits a day and has never crashed.
That is, they will start with some meaningless claim about Linux being good and MS being bad thinking that will give them credibilty and then go on to say how great MS really is.
The strategy used most often is to backup the filesystem and restore from the backup. You do have a backup, don't you? As a sysadmin the two things that make me sleep well at night are a good backup and a good ups.
15G of tape storage is pretty cheap. DDS2 tapes are $7 for 4G.
If you don't care about backups at all, then you could buy a 27G hardrive for $300 and use that.
I have us west dsl and and access my home network remotely. Sometimes my ip addr changes though, and somebody else gets my old ip. It is always funny to then telnet into their 675. An "enable" and "show running" later and you have their password (which is used for email too).
If this site was using mod_perl they could have persistent connections to the db which may have solved the problem. They seem to be using php. Does it have such a feature?
Running a db server on the same machine as the webserver is a bad idea.
Connecting to the db as root is a bad idea unless they removed most of root's priveledges.
Ah yes, that reminds me of my college days at Lawrence University. I was forced to live in the awful Plantz Hall jock dorm. My room overlooked the Ave and Main Hall so I cutout these huge letters and put "F-R-O-N-T-2-4-2" in my window for all to marvel at.
You do not want to get locked into a vendor. That way will lead to pure suffering in all respects: price (both license fees and support) gouging, UI jail, lack of extensibility, slow bug fixes, feature bloat, feature lack, etc. You basically become the vendor's bitch. What are you going to do after you wasted $50 million implementing the vendor's system and then it sucks beyond all belief?
All the open protocols for groupware exist already: SMTP, IMAP, POP, NNTP, MIME, OpenPGP, LDAP, HTML, HTTP, IRC etc. Find applications that use these protocols and you are set.
Keep in mind that any company can publish a spec and say their system is open. But if there aren't competing implementations then it is defacto closed.
Do you want to benefit from all the geniuses at universities? Most cool ideas come from a university, not a company. More likely than not the leading implementations will be free in some sense. They will not integrate into your Lotus Notes monilithic beast easily. Lotus Notes will not copy the feature for another year if at all. Lotus (or IBM) will gladly send a team of $300/hr consultants to come to your site and implement the feature. It will halfway work.
Do you want to rely on the braintrust at a single company company or do you want the power of the IETF, professors, and hobbyists? Think of TCP/IP or BSD.
A great new piece of hardware or OS (think Linux) comes along. No port for Lotus Notes exists for it. You are stuck sending email to IBM begging for a port instead of a recompile.
Recently I decided to use FreeBSD on my machine at work and use OpenBSD as my firewall at home. Each works well. I dutifully subscribed to and read the relevant mailing lists. What is sad is the anti-Linux overtones that permeate the lists. For example, here is part of a message to tech@openbsd.org:
Things that would be nice to have in future releases of OpenBSD -------------------------------------------------- ------------- - i386 multi-processor support (FreeBSD has it, even BSDI has it, and little cousin linux is bragging that is has it.) (I have machines that are dual processor that I had go linux because no no OpenBSD port:( )
Is it necessary to denigrate linux with "little cousin" and "bragging"?
There was no such requirement when I took my test (circa Solaris 2.5.1). They may have changed it. The questions that stuck me were about that over-enginerred saf and the horrible nis+.
I've heard that there are test that rank you above the certified solaris admin peon level. One of those tests might have such a question but I don't think they are for the general public.
The fact that it is stored on your private servers offers little comfort for me since it doesn't protect my information from the company that is most likely to do something stupid with it: amazon.com.
If only I could keep amazon.com from exploiting my precious information for purpose other than allowing me to buy a book. I do not want to send another email to really-fuck-off-this-time@amazon.com or fax an official letter on my company stationary everytime one of the amazon geniuses comes up with a brilliant new idea.

A mink enjoys none of the benefits of the fur coat.
Except, of course, when the mink is wearing the fur coat in the middle of winter in Canada.

Bingo! It seems as though there are many company-specific zombies trolling /. these days, especially Microsoft and amazon.com drones.
Generally, whatever happened to people disqualifying themselves from debate because they have a financial stake in one of the views?
Methinks many of the IT managers force Microsoft solutions on a company because they own MSFT stock.

Yeah, and Win95 is a 32 bit operating system. I wouldn't be suprised if Win64 was actually thunking all the function calls down to 16 bits.

x86 is 20 years old, Unix is 30 years old. Sheesh why are we living in the past?
Ever heard of agism, motherfucker? Everybody was whining when MS attacked Unix for its age and then you do this.
If you weren't an AC I would give you $50 for that hilarious comment.
