 Posted: Mon Jan 09, 2006 11:28 pm Post subject: Debugging install problems remotely. |
 |
|
I am attempting to install Gentoo on a remote server. I ssh into a SUSE machine and then SSH over to the Gentoo machine (after it's been booted on the livecd and ssh daemon started). I have a friend on the remote side helping me with reboots and such. But they are very very new to Linux and don't always communicate exactly what I need to know in order to diagnose problems. I've tried using dmesg but it appears to be the results of the livecd boot not the installed OS boot. Does that sound right? Anyway I can get the dmesg output from the installed OS?
Also, this is taking a lot longer than I anticipated. I am sure my friend is getting tired of me asking them to reboot the machine. My dream is to have the following happen:
* LiveCD boots with default root password, ssh daemon already started, and its IP address emailed to me.
* Once I have all my configuration changes completed, issue a "reboot kernel_name", which would somehow tell Grub to try kernel_name.
* If kernel_name fails to load completely, fall back to LiveCD kernel.
Is that a dream?
Thanks,
Mike |

| Take at the log files in /mnt/gentoo/var/log/ . Especially messages, syslog, etc. Hope this helps! |

Hmmm... no messages or syslog get generated so I guess the boot process isn't getting that far?
All I have is:
| Code: |
livecd ~ # cd /mnt/gentoo/var/log/
livecd log # ls -l
total 244
-rw-rw---- 1 portage portage 13661 Jan 2 14:51 emerge.log
-rw-r--r-- 1 root root 220349 Jan 2 19:19 genkernel.log
-rw-r--r-- 1 root root 0 Oct 19 16:13 lastlog
drwxr-xr-x 2 root root 4096 Oct 19 16:12 news
drwxrwx--- 2 root portage 4096 Oct 19 16:40 sandbox
-rw-rw-r-- 1 root utmp 0 Oct 19 16:13 wtmp
livecd log #

Either that, or there's no logger installed... Also, I think the best you can do is to try to boot one kernel, and then fallback to another one if that doesn't work, but that doesn't seem to help you too much, since I don't think you can fallback to the CD.
I'm *really* intrested in that LiveCD though. Is it something you whipped up yourself, or where could one find that? |
