Please forgive me if this isn't the appropriate forum but I was unable to
locate a general daemontools forum.
I was exposed this week for the first time to both qmail and daemontools. I have a customer whose system was compromised and am trying desperately to get everything back in order. And no... they had no backup strategy. :-(
Qmail is nearly functional with mail being sent and received with minor caveats.
My sticking point is this... While going through the Life With Qmail HOWTO, I
get to the point of testing the start/stop of qmail via qmailctl. Qmailctl stat
returns the message:
/service/qmail-send/log: unable to open supervise/ok: file does not exist
I'm then instructed to do the following:
cd /service/qmail-smtpd/log
svc -d .
Which returns:
svc: warning: unable to control .: file does not exist
Here's what the files look like:
[root@monster-isp log]# ls -l /service/qmail-send
lrwxrwxrwx 1 root root 31 Jun 13 2005 /service/qmail-send ->
/var/qmail/supervise/qmail-send
[root@monster-isp log]# ls -lR /var/qmail/supervise/qmail-send

drwxr-xr-x 2 root root 4096 Mar 31 14:46 log

prw------- 1 root root 0 Jun 14 2005 ok
-rw-r--r-- 1 root root 18 Mar 31 01:45 status
I also performed an strace:

I hope that's not too much for one posting.
If anyone can steer me in the right direction, I would be forever in your debt. I'm extremely impressed with what I've seen thus far of both products and am anxious to learn and begin using both. Oh to finally say farewell to sendmail. :-)
