tcpserver / queue cleaning
Hello, I got too questions about qmail and tcpserver. If the tcpserver program is off topic here, please advise me to the right list. 1. How can I delete every message existing in the queue? 2. I'm using tcpserver to start qmail and it seems to work. But there is a little thing I don't understand. On my FreeBSD 4.2 RELEASE machine I added the follwing configuration file into /etc/rc: /usr/local/bin/tcpserver -p -x /etc/tcp.smtp.cdb -u 82 -g 81 0 smtp \ /var/qmail/bin/smtpd After I added this line I rebooted the machine and it stopped right at the point where it was supposed to excute the line above. It didn't crash and I was able to talk to my server on port 25 it just didn't proccess the rest of the startup scripts. Because it looked the way that /var/qmail/bin/qmail-smtpd was waiting on stdin I added an ampersand at the and of the line so /bin/sh would start it as a background process. It seems to work that way but I'm confused because I read twice in two different docs that no ampersand is needed. At least it wasn't printed there. Can anyone enlighten me? -Moritz

On my FreeBSD 4.2 RELEASE machine I added the follwing configuration file into /etc/rc: That's not the right place to start services, but that's beyond the scope of this list. /usr/local/bin/tcpserver -p -x /etc/tcp.smtp.cdb -u 82 -g 81 0 smtp \ /var/qmail/bin/smtpd After I added this line I rebooted the machine and it stopped right at the point where it was supposed to excute the line above.

In this case you do need the ampersand, but again this is not a qmail question, but a general Unix question. I'd suggest you read http://www.lifewithqmail.org. Set things up as outlined there, and start svscan from a script in /usr/local/etc/rc.d Chris PGP signature

[OT] RE: tcpserver / queue cleaning
I'm using /etc/rc to start the tcpserver process because I read it in Running qmail; Richard Blum. To quote him on that: Once the qmail-smtpd boot script is created, it must be run from a system boot script. On a FreeBSD system this can be the /etc/rc script. Because the qmail-smtpd script just contained the tcpserver line I thought it's no big deal to write it directly into /etc/rc. Anyways, I or the book, one of us sucks. Maybe both. But thanks for the hint I'm going to read Life with qmail and I'm removing my entries from /etc/rc. -Moritz -Original Message- From: Greg White [mailto:[EMAIL PROTECTED]] Sent: Wednesday, July 04, 2001 8:47 PM To: qmail Subject: Re: tcpserver / queue cleaning On Wed, Jul 04, 2001 at 08:26:45PM +0200, Moritz Schmitt wrote: Hello, I got too questions about qmail and tcpserver.

The advice you quote above is further evidence of this. But thanks for the hint I'm going to read Life with qmail and I'm removing my entries from /etc/rc. Yes, Life with qmail is definitely the way to go for most novices. Charles -- --- Charles Cazabon[EMAIL PROTECTED] GPL'ed software available at: http://www.qcc.sk.ca/~charlesc/software/ ---
