Kernel panic. Unsure of cause.
I had just closed Firefox 3 and went to open the Thunar file manager from XFCE and my machine locked up. After ~20 seconds, it rebooted, leaving a 310MB vmcore.0 in /var/crash along with a bounds and info.0 file. I have no idea how to investigate these problems, so please excuse the ignorance that may follow: I followed a section in the FreeBSD Developers Handbook on debugging the kernel, the following means absolutely nothing to me: newton# kgdb /boot/kernel/kernel /var/crash/vmcore.0 [GDB will not be able to debug user-mode threads: /usr/lib/libthread_db.so: Undefined symbol ps_pglobal_lookup] GNU gdb 6.1.1 [FreeBSD] Copyright 2004 Free Software Foundation, Inc.

X.org is 7.3_1. I copied my ~/frank from one computer to another via NFS. May it be there went something wrong? (See below) Check .xinitrc if it is in /root. If it is there and it works copy it over to the /home/user, care for permissions or make it 777. I have only one in ~/frank. Watch for /usr/local/lib/X11/xinit -- it will use this when you have no .xinitrc in the /home/user or permission is set wrong! The file /usr/local/lib/X11/xinit/xinitrc is set to r--r--r--. It seems to me this is somehow wrong. Should I change it, and to which value? Such troubles I solve best when I look over it the next day. Usually I find it in two minutes then and wonder how I can have not seen such an obvious mistake..

unsure about /etc/hosts
Hi, I am at the moment unsure about the localhost entries in my /etc/hosts. From /usr/src/etc/hosts I have found this one: # Host Database # # This file should contain the addresses and aliases for local hosts that # share this file. Replace 'my.domain' below with the domainname of your # machine. # # ::1 localhost localhost.my.domain 127.0.0.1 localhost localhost.my.domain So my hostname is I.and.I so the /etc/hosts entry must be: ::1 localhost localhost.and.I 127.0.0.1 localhost localhost.and.I Now regarding some programs (e.g. mutt) this option is not able to deliver mail locally instead putting it in /var/spool/mqueue or /var/spool/clientmqueue. If I use this: ::1 localhost I.and.I 127.0.0.1 localhost I.and.I I have no problems with sending the mail locally. So I am a little bit confused about what is the correct way to define the localhost in /etc/hosts.
