[techtalk] ipchains
Hi there. I'm having a little trouble understanding the ipchains ruleset. I've read over a few how-tos, but haven't quite mastered it. If I had a program that needed TCP port 510 and UDP port 810, how would I go about setting that up to run through ipchains? If someone knows a comprehensive how-to, I'll accept that instead of an explanation. I just need to figure out these rulesets. I'm actually migrating from an NT4 server as a proxy/file server, and though I knew the rulesets for my firewall/proxy on that machine, I have no idea about these ipchains rulesets. Thanks There's plenty of semicolons to go around ___ techtalk mailing list [EMAIL PROTECTED] http://www.linux.org.uk/mailman/listinfo/techtalk
Re: [techtalk] ipchains
Well, for Asheron's Call, this is how I did it: ipchains -A input -p tcp -j ACCEPT -s 0.0.0.0/0 -d 192.168.0.5/24 9000:9010 ipchains -A input -p udp -j ACCEPT -s 0.0.0.0/0 -d 192.168.0.5/24 9000:9010 Now where the line for tcp is, substitute in 510:510 and for udp, 810:810. Also, where 192.168.0.5/24 is, substitute in your IP and subnet mask.

Re: [techtalk] ipchains
Thanks Kath. Much appreciated. Though I have also discovered one other problem. One of the other machines here cannot access email using outlook express. I can use fetchmail with no problems from the firewall box, but outlook to my isp is a no go, any chance you might know how to handle that?

Not a stupid question at all! My still-fairly-new-to-the-industry
understanding is this:
Theoretically, it's a PC Tech exam, designed to say to the
world (and to prospective employers), "Hey! I can diagnose
your PCs hardware woes, fix it, and/or jury-rig you a new
one ... all in my sleep!" It is mostly hardware and DOS
issues (since the people who make up the A+ test have
yet to realize that DOS is not the only tool with which to
diagnose a PC.
Realistically, I'm told it is largely made up of useless trivia,
like "How often should you clean a keyboard?" ("As often
as I spill my Ramen Noodles on it?"). Hence the need to
buy a study guide, so you'll know what kind of useless
trivia is found on it.
But, it looks good on a resume.

Re: [techtalk] Re; A+ Certification
Actually the A+ cert. is a good reflection of what a PC mechanic needs to
know. I know 'cause I have it. There are no trivial questions. See
http://www.comptia.org/certification/aplus/aplus_revision.htm for the latest
information.
As it is a multiple-choice test, it is not as rigorous as a hands-on exam,
but you have to know your stuff, you can't guess the right answers. The best
self-study exam prep is Mike Meyers' A+ Certification Exam Guide. In fact I
recommend it as a good all-around how-to book.
Some employers value it, some don't. Either way it is a meaningful
certification, you have to understand PCs very well to pass it.
