Re: [Alug] basic routing/config NO-prob for mail
Main cause of problem was ignorance about how WINS and DNS work, probably.

If you don't feel you want to answer my questions, I don't expect that, but believe me, i spend a lot more time looking around for information on the net and in books than i do asking alug questions. If i have completely ground to a halt or feel a pointer in the right direction will help, then i'll ask - isn't that what a user group is for? OK, there could be a few hundred books out there that will supply me with the same information but m,y time and financial resources are extremely limited. The very fact I didn't know that what was with the wins and dns stuff is what stopped me going to look it up in the first place (if you follow).

Nor was I, it has taken many years to build up the little knowledge that I have. I my self have asked lots of stupid questions and also admitted to being wrong (publically on list). I have been where you sit now but with people just saying RTFM, and as such have sat and read "Computer Networks" and also "TCP/IP Network Admin", I was about to make a comment about this book then realised that I have your copy on my desk at home. I would also wory if TCP/IP did ooze from your pores :o)

Sorry, I don't mean to diss you atall. Your achievements are very admirable, for someone of your age to learn what you have is amazing. I didn't realize you were 37 btw.
didn't have such a beast as a computer in school (no, we had to do cookery and sewing), and think I'm piecing stuff together not too badly considering.
Wow, you can sew too, I can't, I'm getting more impressed :o) seriously, like i said what you have achieved is amazing, very few people like you would get very far on this. Also as for cookery, have you noticed its very similair to computing, you have to be careful what goes in (hardware and software compatibility) and then you have the basic constructs of programming - sequence, selection and interation... OK I'm waffling.
If you don't feel you want to answer my questions, I don't expect that, but believe me, i spend a lot more time looking around for information on the net and in books than i do asking alug questions.
Don't worry I have no problem with answering questions, and you have my phone number so if you get very stuck you can call me. Most of your questions are very much show stoppers, and interesting challenges to meet.
If i have completely ground to a halt or feel a pointer in the right direction will help, then i'll ask - isn't that what a user group is for?
A user group is for exactly what you use it for, the fact that you can't find the info out on the web in the howto's etc.. is more a reflection on the poor quality of the docs, which I know some people will say are very good, and I will agree that for most things this is the case, they don't cover much what happens when things all go pear shapped.
OK, there could be a few hundred books out there that will supply me with the same information but m,y time and financial resources are extremely limited.
I often don't have time and I too ask these questions, see UFS and samba threads, also kernel recompile questions etc...,

WINS and DNS is a black art and I will admit that I don't understand it, I just edit the resolv.conf file and hope, ok mostly hope. I like the motto BTW. You may also note that I have asked lots of questions about printers and will be bringing it on sunday for help configuring it. Now I have already read the instructions which came with it and also the linuxprinting howto, and I still don't understand it. Don't be afraid to ask a question, the only stupid question is one which isn't asked.[1] Thanks D [1] please don't mention the think geek poster tho. PS you don't fancy getting IP firewalling working on my box on sunday, I'm stuck.

iptables or ipchains? I've got a nicely downloaded bash script for IP tables laying about if you want it, its worked for me for a while now (basically since shifting to kernel 2.4). I use it because I haven't had time as yet to get my head round iptables, ipchains where far simpler in comparison. Cheers, Brett
Eh, iptables/chains are almost identical, in firewalling sense, but not in masquerading. eg ipchains -I input -p icmp -j DENY becomes iptables -I INPUT -p icmp -j DROP ie, you change the chain to caps, and deny to DROP. Pretty identical, including the --syn option. I have been able to convert all my ipchains rules to iptables without incident. My NAT boxes run on ipchains still, as some things still don't NAT properly under 2.4/iptables. Whats really cool with iptables is that you can mark packets in the PREROUTING table, and use netfilter to do cool things like rate-limiting. See Advanced-Routing-HOWTO for more on this.

Ahh, the script does both, masquerading is *completely* different, it confused the hell out of me hence downloading the script. I might hack the script later, make it slightly more tailored and possibly convert it to an init.d script as the old ipmasq in deb was.

And the incredible amount of information you can get by logging anything and everything.... Cheers, Brett
Hi all, Am having some niggly problems with cron on RH6.2 and 7.0 RH6.2 cron hangs after executing all the scripts in /etc/cron.daily. It hangs on a sendmail which I presume is cron mailing the results of run-parts to root. Can't see any reason why it should do this. RH7.0 again, cron hangs after executing all the scripts in /etc/cron.daily but shows more information about 'awk' (part of run-parts script). I still see a sendmail process there in a sleeping state as per RH6.2 Anyone else seen this behaviour? Cheers. Mark W.
