My first non-x86 Linux box is already installed, networked, running X and compiling things, so it's not going too badly.

The problem that tends to come up though, is that all the easy answers get answered and the complicated problems get ignored. This is a trend in mailing lists in general. I wish I knew an easy answer :) People are prepared to provide answers from their personal knowledge for free, but not do research projects for free. Unfortunately the easy answer is probably summed up in the sentence You get what you pay for. For instance, I want to figure out what country an AS number is in, without doing mass whois querys. Like for instance: % whois -h whois.apnic.net AS9800 Will tell me that that AS number is in China. I'd like to be able to (say) block all of China from accessing my SMTP port for instance. I've got a BGP dump of prefixes to AS numbers, so that I can figure out what IP subnets belong to which AS number. Now this is a challenge to see if anyone has any ideas :P One quite good way of stopping spam is to check the reverse lookup on the DNS. If, as is almost always the case with spam, there is no reverse lookup you can just redirect to /dev/null . It's not 100% proof but together will the other, standard, measures it can be a big help. -- C.

I am sure I speak for most here if I say that no one objects to answering even the most basic of queries. I'll even go as far as to say that some of the answers to these early 'what the...' questions are even useful to the more experienced user. Just my 3 cents... Adrian

If I see something asked a lot, I think: That needs fixing. On the odd occasion I've even submitted code patches to fix it!

Given the speed of your reply, Nick, I wonder if steering my daughter toward studying for a law degree was a good idea... H... maybe it was vbg Adrian Nick Rout wrote: Well, I normally hate, 'me too' posts but this one deserves it :) Adrian me too (hell Adrian, you asked for that LOL)
