Resources for ISP Sysadmins?
Okolo Callender asks: "I work for the local telephone company on one of the Caribbean islands, and am the tech in charge of all internet services. Most of my time is spend maintaining our ADSL network. With almost no training, I have become quite good at maintenance and troubleshooting of our network, however I am finding it difficult to find books or online information that tackle tips and techniques more specific to ISP admins. General LAN networking info and raw Cisco documentation is fine, but I would like to find more 'cookbook' style solutions to common ISP-related problems. What books and/or online resources can the Slashdot crowd recommend?"
I use Google.com a lot. Lots of info...

Check out the presentations and the resources links.
Lived on usenet during my early ISP days, since there wasnt many places you could get info on setting up routers or portmasters, or even configuring radius, usenet was the place.
Too bad usenet is dieing and forums are taking over. Thats just sad.
One of the best resources available...

Shouldn't the ISP admins write the books?
They'd love to answer all your questions about how to run an ISP for you - and if they really like you they might even let you in to the other place!

If you're self taught and in the thick of it you probably know more than most people. I expect you don't realise how much experience you've gained. Maybe you should consider putting up a site for other people in a similar situation to you, if you're seeing the need for one.
I was conned by an old man in a cloak. It turns out those *were* the droids I was looking for.
At my job, they recently signed us up for Sillport (an e-learning system), which also includes a subscription to books24x7.com. This is a coleciton of several thousand technical and business books, fully searchable and browsable online. I think a personal subscription runs about $400 a year, hopefully you can get your boss to expense it for you. Well worth it in my opinion.
I truly enjoy my new life as a whore. My husband CmdrTaco has a collection of
over 150 tapes of me with other men. He has sold copies of several of them.
There's a couple of tapes that get the most requests and they are also the ones
of the times I enjoyed best. One of the most popular tapes was made when I was
gang fucked by six men. One of Cowboy Kneal's friends was supposed to come over to
the house to fuck me. He showed up with four other men, all black, and they
asked if they could all be taken that night! I told my husband that there was
no way I could fuck six, big, black men all in one night! CmdrTaco told the men
that I would only take two of them but the rest could watch and make an
appointment for some other time. The men agreed and cut a deck of cards to
settle who would screw me and who would watch.
The two men who won the draw for for me paid my husband $200, each, and
seemed very anxious to get started. They flipped a coin to see who would fuck
me first. Cliff, a tall, heavy man, won the coin toss. I told him we could
go to the bedroom and get started. I was wearing only my bra and panties and
asked Cliff if he wanted to undress me or if he wanted me to strip for him.
He didn't say a word when he came up to me and put his large hands on my bra
covered tits. He squeezed my jugs for a few moments before unclasping my bra
and pulling it off. After feeling my boobs and flicking the nipples with his
index finger, he stripped naked. I looked down at the black man's stiff cock.
It was large, like other black men's that I've fucked and it was as black as
night.
Cliff's hands went back to my tits. I held his cock with one hand and
smoothed my fingers over the large cockhead with the other. He kissed me
intensely for the next few minutes and then said, "Yeah, let's get to it baby!"
The other five men standing around (six including my husband who was taping
us), watched in silence while I peeled my panties off. I stood naked in front
of everyone and said, "I can't wait to get that fat black cock in my pussy!" I
started to get in bed when Cliff stopped me with, "Let's do it on the floor,
baby. I can fuck a lot better down on the floor."
I winked at the tall, black man and said, "You going to fuck me from
behind, with your big black cock, Cliff?" He stared at my naked cunt,
answering, "Yeah, baby! In back of your white ass! I'm ready to slide this
black snake into that big white pussy of yours.!" I kept my eyes trained on
Cliff's buddies as I kneeled on the floor and then went down on my forearms.
My cunt was easily accessible from behind my ass and I knew all who were
watching had a clear view of it. My tits hung to the floor, tickled by the
shag carpet. When Cliff kneeled behind me, I asked, "Oh, Cliff, honey? Lick
my pussy a little before you fuck me. Please, please lick my cunt, Cliff!" He
lowered his head under my ass and I felt his tongue slide along the parting of
my cunt lips. I arched my back to raise my ass even higher. Cliff's probing
tongue managed to part my pussy lips and penetrate into my musky fuck hole. He
went back to his kneeling position and I heard the other men saying "Man! Look
at that pussy!" and "It's so big and fucking wet, man!" and "Yeah! She's ready
for fuckin' OK!"
When the black man's cockhead pressed at the opening to my cunt I peered
over to the men watching and said, "Ooo! Yeah! He's gonna' fuck me now! With
his big, black cock, he's gonna fuck my wet cunt, now! I love being watched
while I get fucked!" Cliff gripped my ass and slid his hard dick into my
waiting cunt. I moaned the entire time he fucked me! The angle that he had to
my cunt, caused the top side of his long meat to glide along the parted cheeks
of my ass. I could feel his cunt juice coated cock slipping along my asshole
as he drove his dick up my twat.
Soon, Cliff was fucking

Hmmm, a post from an admin of an ISP saying that he does not have training on his systems etc.
A little searching and you can find that ISP - what are the odds that there will be a few misconfigured devices that leave a security hole or two because the underfunded admin never got that information.
And then the attacks begin....
In general your going to have to find books on each specfic technologies. Most of the general ISP resources are from the mid 90's when dial up was all the rage.
/w OC-3 cards, multilayer switches, DSLAM's and wireless bridges. Got a chance to mess around with a good mix of different layer 1 and layer 2 technologies along with a few different routing protocols. One course I totally underestimated was level 2 to 4 switching, I had no idea that ethernet switching was so complex.
An ISP sysadmin is a very specialized area and over the past few years the field has gotten smaller and smaller with everyone buying out everyone else. So your pretty much on your own.
I've just spent the past year doing Telecom Eng. Technology at the Collage of the North Atlantic. The courses included L2 to L4 switching, tcp/ip, network cabling, LAN's and DSL(Why they put these together), digital telephony, voip and prevoius to that I did a mess of eletronics and math courses. That broad range of courses still left out alot of topics which I covered on my own. I really made of the best of all the lab time I could get, built my own model internet out of old 2600 serise routers, a few linux boxes
Anyway my point is, you have to understand the underlying technologies and from there build a working knowledge of how to use your equipment at hand.
Oh yea and don't underestimate the power of linux in networking. A linux box can handle just about any task/service above layer 2, just gota get good hardware and with the money you save not buying cisco buy two or more, so you can always have a hot backup.
God, root, what is the difference?

I've been in a similar situation before. I never really found many ISP-specific resources. There's discussion boards that pertain to ISPs but mainly I used that resources that broke it down by specific service or task. ie spam filtering, virus prevention, network redundancy, security, bonus user services, administration ease, etc. An ISP has to encompass all of that and more, much more so than any other IT shop. Plus you have to do it on a budget and you have to not piss off the paying customers, all while attracting more paying customers. It's a challenging environment. Best of luck.
I work for the local telephone company on one of the Caribbean islands, and am the tech in charge of all internet services even though I don't really know what I'm doing.
Tell your boss that I do know what I'm doing and am willing to work in the Caribbean.

It is a bit dated but still good.
Also an excellent way to sell a honeypot to unsuspecting slashdotters.
Probably a nice move for recruiting hackers actually.
Or maybe not?
>>>"I almost cut and paste into google and report the findings and get modded up as informative"
I imagine that's because most of us have no real deep incite into the subject but comment anyway and so degrade the signal-to-noise level.
With a google you can get comments like "use Z-product it has this feature". With experience you get "while Z-product has this feature that should save hours of work, I found that unless I did X-action first it took twice as long".
Google is great but knowledge does not equal wisdom.
If there's only a few of you I'd have thought that a group library of n x $400 would be enough resource to keep you reading for the year. Maybe about 8 people would have to club together.
...
Also libraries here in the UK will get books for you if you order them. They can order from other libraries or will buy if necessary. I think you have to pay a small fee to show willing. But it's small compared to the cost of buying the books.
The books24x7 thing sounds great for reference material (http://marketing.books24x7.com/browseabout.asp) but if you want to read something
ipfw add allow tcp from your.isp.subnet/xx to your.mail.server.pool/xx 25
ipfw add deny tcp from your.isp.subnet/xx to any 25
