[vchkpw] POP not working.. am at a loss
Good afternoon, I have the following problem I am runing Qmail + VPopmail On Debian Sarge with kernel 2.4.27 When I do "telnet localhost 110" I get a prompt, but when I enter a correct username / password combination, i get: USER username OK PASS password Connection closed by foreign host. When I enter a false combination, I get an error message. I have enabled verbose logging in vpopmail and get all authentication attempts and can see they are succesful, so im assuming vpopmail is doing its job. When I look at my /service/qmail-pop3d/run script: #!/bin/shexec /usr/local/bin/softlimit -m 400 \ /usr/local/bin/tcpserver -v -R -H -l 0 0 110 /var/qmail/bin/qmail-popup \ `hostname` /home/vpopmail/bin/vchkpw /var/qmail/bin/qmail-pop3d Maildir 21 I'm guessing something is not passed correctly from vchkpw to qmail-pop3d but i have no idea what. The output of "netstat -ap | grep pop3" is: tcp 0 0 *:pop3 *:* LISTEN 5455/tcpserver which is, i think as it should be. The relevant section of pstree is svscanboot,1001 /command/svscanboot svscan,1004 /service supervise,1006 qmail-send qmail-send,5445,qmails qmail-clean,5463,qmailq qmail-lspawn,5459,root ./Maildir/ qmail-rspawn,5460,qmailr supervise,1007 log multilog,5446,qmaill t s250 n10 /var/log/qmail supervise,1014 qmail-smtpd tcpserver,5450,qmaild -v -R -l[MYHOSTNAME] -x /etc/tcp.smtp.cdb -c 20 ... supervise,1015 log multilog,5452,qmaill t s250 n10 /var/log/qmail/smtpd supervise,4332 qmail-pop3d tcpserver,5455 -v -R -H -l 0 0 110 /var/qmail/bin/qmail-popup ... supervise,4333 log multilog,5457,qmaill t s250 n10 /var/log/qmail/pop3d Where i also didnt see anything wrong. I have checked permissions with my production servers which are running the same installation and they all appear the same. Both hosts.deny and hosts.allow don't contain anythning Any ideas what i can do to get my pop working ? - Steven

Mine is the same as yours except I have no softlimit and I run it as user root, group root (-u 0 -g 0, because I have separate users for some domains with system quotas) Regards, Rick
Re: [vchkpw] POP not working.. am at a loss
I added a 0, making it 40mb for a softlimit, unfortunately it didn't make a difference. Removing it completely also didnt make a difference. I can execute other vpopmail commands, they wont return any error message so i know the database connection is working properly. - Original Message - From: Rick Macdougall [EMAIL PROTECTED] To: vchkpw@inter7.com Sent: Thursday, August 11, 2005 5:02 PM Subject: Re: [vchkpw] POP not working.. am at a loss Wouter van der Schagt wrote: Good afternoon, I have the following problem I am runing Qmail + VPopmail On Debian Sarge with kernel 2.4.27 When I do telnet localhost 110 I get a prompt, but when I enter a correct username / password combination, i get: USER username OK PASS password Connection closed by foreign host.

Hi, Try adding recordio before the qmail-popup and see if anything shows up in the logs. Regards, Rick PS. Try not to top post if possible.
Re: [vchkpw] POP not working.. am at a loss
I changed /service/qmail-pop3d/run to: #!/bin/sh exec /usr/local/bin/softlimit -m 4000 \ /usr/local/bin/tcpserver -v -R -H -l 0 0 110 \ recordio \ /usr/local/bin/recordio /var/qmail/bin/qmail-popup \ `hostname` /home/vpopmail/bin/vchkpw /var/qmail/bin/qmail-pop3d Maildir 21 And when i do telnet localhost 110 and enter username and password i dont see any output of recordio. I have also tried removing the 21 in the end, but to no avail. - Steven

The logs should show up in your pop3d log file, where ever you have that stored. Regards, Rick
Re: [vchkpw] POP not working.. am at a loss
I noticed it also, it was a mistake, a changed the run file, and ran the
trace
the recordio log is:
400042fb8f491ec572f4 6402 +OK
400042fb8f5413c04c1c 6402 pass test
@400042fb8f541557208c tcpserver: end 6402 status 256
@400042fb8f5415573414 tcpserver: status: 0/40
@400042fb8f5415585524 6402 [EOF]
TCPServer status 256, i think means exit, but i have no idea why.
The output from the strace is: (after the password)
