I wouldn't ordinarily recommend reinstallation, but it's probably quickest
for you);-((
The difficulty is thinking of some rectification you'll understand.
If you have an RHL 6.1 CD to hand, it's likely that updating will fix the
problem.
Almost no user's problems are fixed by deleting or even changing files in
/etc.
If you want to try to repair it, the solution's with the rpm command.
I'f you need to boot, at the lilo prompt enter something like
lilo vga=ask
When it asks you, choose a number that gives a decent amount of text on
your screen; you'll probably need it;-). I use 6 which gives me 80x60.
Login as root.
Try this command:
rpm --verify `rpm -qa` | less
The command "rpm --verify" checks that the specified package is installed
properly.
The "`rpm -qa`" bit uses rpm to get a list of installed packages and
inserts the list into the commandline. The quote marks are called
backticks and are the unshifted key to the left of my "1" key.
"| less" takes the output of the "rpm --verify" command and displays it in
a controlled manner on your screen. You can page up and down and search.
The man page of rpm suggests there could be quite a bit of output to read.
You should get a few rpms that have missing files.
You can reinstall them thus:
rpm --upgrade ...
and supply the full pathname of the rpm you need.
fwiw Here are the *.conf files I have.
/etc/host.conf
/etc/X11/gdm/gdm.conf
/etc/nsswitch.conf
/etc/httpd/conf/access.conf
/etc/httpd/conf/httpd.conf
/etc/httpd/conf/srm.conf
/etc/named.conf
/etc/dosemu.conf
/etc/gpm-root.conf
/etc/pwdb.conf
/etc/security/access.conf
/etc/security/group.conf
/etc/security/limits.conf
/etc/security/pam_env.conf
/etc/security/time.conf
/etc/ld.so.conf
/etc/logrotate.conf
/etc/ltrace.conf
/etc/mtools.conf
/etc/inetd.conf
/etc/nmh/mts.conf
/etc/pine.conf
/etc/smb.conf
/etc/syslog.conf
/etc/snmp/acl.conf
/etc/snmp/context.conf
/etc/snmp/party.conf
/etc/snmp/snmpd.conf
/etc/snmp/snmpd.local.conf
/etc/snmp/view.conf
/etc/ntp.conf
/etc/yp.conf
/etc/lilo.conf
/etc/resolv.conf
/etc/isapnp.conf
/etc/wine.conf
/etc/cdrecord.conf
[summer@possum summer]$
Not all are critical for my system's
operation. Some that are might not be fixed by the action I've outlined;
This comes to mind:
/etc/resolv.conf
Mine looks like this:
[summer@possum summer]$ cat /etc/resolv.conf
search os2.ami.com.au
nameserver 192.168.1.2
[summer@possum summer]$
but yours must have different values. I expect tha some fiddling with
linuxconf will fix that problem
Have fun.
