Hi Folks
Having fun and games here trying to track down a bug that is causing my kernel to crash and do a cold boot.
Much of the information I need is in the /var/log/dmesg (oops reports, etc), but this is overwritten on the next boot - Question: Is there any way of saving an old dmesg log at the next boot ?
I've tried adding a "mv -f /var/log/dmesg /var/log/old-dmesg" to the end of rc.sysinit, but it copies the current dmesg log.
Regards, Paul.
Hello
I think I probably met some of you at a 'Linux Install Day' some months back when my friend Ricardo tried (unsuccessfully) to get Debian on my machine. (The problem centred on Debian not supportinf my Graphics card).
I have since aquired Mandrake 9.0 and have installed this on my machine. But am having trouble with the internet connection. I have to use the wizard to connect it each time, since if I don't it will seem to connect okay, but the connection won't be available to any programs.
kppp thinks it is connected, and my phone is definitely busy with modem noises until I hang it up, but the kde control centre says I'm not connected and I can't get kmail or konqueror or any other internet program to work.
The only way I can get back online is to use the wizard again, which is a big pain for me and just too difficult for my girlfriend...
I have two computers and the same problem occurs on both.
One is an AMD 900, dual booting with Madrake 9.0 and M$W98SE and the other is an Intel Celeron 300, with just Mandrake 9.0
So I think the problem is either with my modem or with Mandrake 9.0, which are the only things they have in common. Or it could be the KDE desktop. I haven't tried the Gnome one. I'm new to all this and I thought I'd just try and learn one at a time...
Thanks in advance for any help.

erm....
Are you connecting to the 'net through the same modem on both machines? Have you tried pinging a site?
At a first guess, without knowing the answers to the above (especially the first question) I'd hazard a guess that it's mandrake causing the problem, perhaps not detecting your modem correctly??
/me steps aside so someone who knows how to configure modems correctly can take over...

I am wondering if it's a DNS nameserver issue.
Can you ping sites by IP address, try ping 163.244.64.253 (which is www.dell.co.uk)
If that works then I guess that your /etc/resolv.conf file is in a poorly way Post the contents of that file here so that we can take a look.
If the ip ping works then can you type nslookup and tell us what it reports back as the default server and address
If the ping is not working can you post the results of ifconfig (run as root) whilst you are connected with the fault in question.

Try setting the connection up using the manual setup in kppp. You may need some info about your isp, but there is an option that allows you to enter pppd commands. Add usepeerdns to this because you may not be specifying a DNS server at the moment. Also, are the 2 pcs networked? Make sure you set up the routing so that ppp0 is the default route once you are connected.

well in Debian it appears to be part of the bootmisc.sh script in /etc/init.d but from memory I think you are using Redhat. Anyhow all I did to find where it gets set was a grep -r dmesg * in /etc and it looks as though it just overwrites the file at bootup on Debian but you could either put a boot script in before this to rotate the logs or move them elsewhere i guess.
If you want further help I can look on a Redhat box at work tomorrow.

Hi Folks
Having fun and games here trying to track down a bug that is causing my kernel to crash and do a cold boot.
I have had the same problem with about 4 computers at work. It turned out that some of the capacitors near the CPU's were leaking and causing the computers to reboot. Below is a slashdot article about the problem.

Thanks Aaron
But it is not a hardware fault causing the reboot - I have a kernel module loaded that will crash when fed with specific data, it is repeatable, and will always bring the system down.
Found it was down to a null pointer being referenced, so a quick check is made first. A chance to view the oops report first might have made it a little easier to nail.
Regards, Paul.
P.S. Thanks also to Adam and Steve for their comments.

For the past few hours I've been trying to get fetchmail to work nicely so I can become all nostalgic for my university days by using pine. Unfortunately I am getting the following error message when running it:
message for psychoferret.freeserve.co.uk at pop.pol.net.uk (3064 octets). reading message 1 of 1 (3064 octets) ..fetchmail: SMTP error: 451 4.1.8 Domain of sender address main-admin@lists.alug.org.uk does not resolve . not flushed
I', *guessing* this is to do with sendmail not knowing what to do the mail it receives, although my fetchmailrc contains 'poll pop3.blah.com user blah as ben' (my logon name for my box).
can anyone help please? I can't glean anything useful from the sendmail man page and my small collection of o'reilly books isn't much cop either.
::sniff::
all I want is to pretend I'm still at uni...
cheers,
Ben

You don't say what sendmail and what distribution you're using, so I can't be specific. You probably need to add some setting to accept any emails from localhost without putting it through spam traps like resolving the email address. Alternatively, if you're taking DNS settings from your ISP, restarting sendmail after PPP comes up may make it work for this case, but might not work in general.
Hope that helps,
