So, I have a few experimental Freebsd 5.4 cpanel machines. One just started acting very funny. For a while we couldnt login remotely because it was reporting errors with /etc/spwd.db.
After logging in via single user mode, i started investigating:
ls -l /etc/spwd.db
ls: /etc/spwd.db: Bad file descriptor
ooooook, what the hell. Anyway, I wasn't able to write to it, rm it, etc, but I was able to rename it to spwd.db.BAD
I regenerated the file with pwd_mkdb /etc/master.passwd .
Now, 2 days later, I'm getting oddball errors, and a bunch of my files in that folder are messed up as well..!
[email protected]# for i in /etc/*; do ls -l $i >/dev/null; done
ls: /etc/bleh: Bad file descriptor
ls: /etc/bleh2: Bad file descriptor
ls: /etc/master.passwd,v: Bad file descriptor
ls: /etc/pwd.db: Bad file descriptor
ls: /etc/quota.conf,v: Bad file descriptor
ls: /etc/relayhosts: Bad file descriptor
ls: /etc/relayhosts.bad: Bad file descriptor
ls: /etc/relayhostsusers: Bad file descriptor
ls: /etc/relayhostsusers.bad: Bad file descriptor
ls: /etc/spwd.db.BACKUP20061103: Bad file descriptor
ls: /etc/trueuserdomains: Bad file descriptor
ls: /etc/trueuserowners: Bad file descriptor
Trussed it, nothing useful:
stat("/etc/pwd.db",0xbfbfe5a0) ERR#9 'Bad file descriptor'
lstat("/etc/pwd.db",0xbfbfe5a0) ERR#9 'Bad file descriptor'
open(".",0x0,00) = 3 (0x3)
ls: write(2,0xbfbfd9b0,4) = 4 (0x4)
/etc/pwd.db: Bad file descriptorwrite(2,0xbfbfd9d0,32)
Tried it in perl, no dice:
[email protected]#perl -e'
open(FILE, "/etc/relayhosts.bad") or die("$!");
close(FILE);'
Bad file descriptor at -e line 2.
I tried fsck'ing the / partition, and it did NOTHING. Anyone have some insight into this? It's a bit odd that only cpanel-related files stuff are being affected here...
