NMBD crashing in 2.2.7a (and 2.2.6, 2.2.5)
Hi all,
I've been having a problem with nmbd crashing multiple times per day.
I suspect that the problem is caused by a shell script that tries to
lookup the name for ws to ws4000 to build a DNS reverse table.
It look something like this:
#!/bin/ksh
typeset -Z4 i=0
while (( $i 4000 )); do
host=ws$i
nmblookup $host | awk -v host=$host '
/^[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+/ {
printf(%s IN A %s\n, host, $1)
}
'
(( i = i + 1 ))
done
I have a level 10 debug log which I could send if it would be useful.
Let me know if there is any more information I can provide.
Bob

RE: NMBD crashing in 2.2.7a (and 2.2.6, 2.2.5)
Sorry, I forgot to include smb.conf. I am building the 2.2.8 release now
and will install it in the next couple of hours (assuming all builds
cleanly)
so any testing can be done against that release.
The current (2.2.7a) release we built with the following:
CC=/opt/SUNWspro/bin/cc ../../configure \
--with-automount \
--with-msdfs \
--with-nisplus-home \
--with-readline \
--with-pam \
--with-syslog \
--with-utmp \
--with-tdbsam \
--with-libsmbclient \
--with-configdir=/etc/samba \
--with-privatedir=/etc/samba/private \
--with-codepagedir='${prefix}/codepages' \
--with-lockdir=/var/samba/locks \
--localstatedir=/var/samba \
--mandir=/usr/local/share/man

Hi all,
I've been having a problem with nmbd crashing multiple times per day.
I suspect that the problem is caused by a shell script that tries to
lookup the name for ws to ws4000 to build a DNS reverse table.
It look something like this:

/^[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+/ {
printf(%s IN A %s\n, host, $1)
}
'
(( i = i + 1 ))
done
I have a level 10 debug log which I could send if it would be useful.
Let me know if there is any more information I can provide.

I think this is a bug we fixed for 2.2.8. Can you please

Thanks, I've built and installed the 2.2.8 version. I'll give feedback on
Monday.
