qmail-popup
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, A question about qmail-popup. Here is a part of the qmail-popup manual. qmail-popup expects descriptor 0 to read from the network and descriptor 1 to write to the network. It reads a username and password from descriptor 0 in POP's USER-PASS style or APOP style. It invokes subprogram, with the same descriptors 0 and 1; descriptor 2 writing to the network; and descriptor 3 reading the username, What use is it to give descriptor 2 as writing to the network i'v checked the source for qmail-pop3d and did not find anything that wrote to descriptor 2. Are there any programs out there that do use it? I know descriptor 2 is stderr so it could be that when an error msg is send to stderr it is send to the network, but how can you do logging in this case. My patch for pop3d loggin disables this feature and send the error msgs from qmail-pop3d to stdout(1) and stderr(2) so that the error is send to the network and also to any logging program that is used. Any comments on this.

Hi all,
I wrote a small patch to do some logging of POP account usage.
I only wanted to have some loggin of users loggin in and the message

facilitate incorrect login attempts and other errors. NO PASSWORD are
written to the logfile.

qmail-popup syslog messages
Hi, Several people asked this on the list before, but I have not found any reply. I hope to have better luck... :-) Every time the mailbox is checked with POP3, syslog reports: Mar 7 15:40:48 net1 inetd[26701]: pid 26937: exit status 1 Other than the annoying message, everything seems fine. This is what I have in inetd.conf: pop3 stream tcp nowait root /usr/sbin/tcpd /opt/qmail/bin/qmail-popup net1.alma.ch /opt/qmail/bin/checkpassword /opt/qmail/bin/qmail-pop3d Maildir (on 1 line of course) Adding "qmail-popup" before the hostname doesn't solve it. (If I remember correctly, it breaks the service) Changing "pop3" to "pop-3" breaks it as well, with another error I don't understand: Mar 7 14:41:36 net1 inetd[418]: pop-3/tcp: bind: Address already in use The system is a redhat 6.2, in case it matters. Thank you, Milivoj
qmail-popup process not starting successfully at boot
Still trying with this one - but maybe it's obvious to someone . When our SUN box reboots pop3d does not start. The when you check mail you get "An error occurred while sending your username to the mail server ..." All other qmail services appear to start - and when you re-run /etc/init.d/qmaild stop/start qmail-popup starts OK. I think that this is an environment/path problem In /nohup.out is the line 'env: No such file or directory' caused by the 'nohup /var/qmail/start-pop3d' command. Any pointers as to the possible cause of this problem would be appreciated. Many thanks The following 4 diagnostics represent two outputs of ps -ef and the two files that 'do the work'. = 1).

qmail-popup question
From the qmail-popup man page: qmail-popup expects descriptor 0 to read from the network and descriptor 1 to write to the network. It reads a username and password from descriptor 0 in POP's USER-PASS style or APOP style. It invokes subprogram, with the same descriptors 0 and 1; descriptor 2 writing to the network; ^^^ I'm curious as to why this is done. In particular, stderr output from the subprogram is being fed back to the client, which is probably expecting a pop3 +OK/-ERR response, rather than whatever happens to be sent down stderr at the time. Wouldn't it be better to leave stderr alone, so that it could be fed to logger/splogger/multilog? -- Chris Mikkelson | "I have yet to see any problem, however complicated, [EMAIL PROTECTED] | which, when you looked at it the right way, did not | become still more complicated." -- Poul Anderson

I The answer (i believe) is simple: 'no'. am trying to use $HOME/Mailbox for mail and gather my remotely via POP-3, but I keep getting the message: [boring error message cutted out] I think that is more safe and reliable use the Maildir format and make some wrappers arround your MUA's to convert the maildir to mailbox on-the-fly. In a general line: Using pine as a MUA, built a shell script like this: #!/bin/sh # see more details in the maildir2mbox manpage. MAILDIR=~/Maildir/ MAIL=~/Mailbox MAILTMP=~/Temp_mailbox /var/qmail/bin/maildir2mailbox exec pine This will convert maildir format to mailbox (and let pine read it). This also solve your problem with the qmail-popup. It's obvious that if you have only pop/Imap clents you *must* convert to Maildir. It's easy and painless. :-) Keep trying.

If you prefer to use mbox format mailboxes you can use qpopper and for imap you can use uw's or any number of other imapds.

I do have a logger patch but it's broken. AFAIK it's a waste of time to
talk about logging qmail-pop* until we cannot do logging with tcpserver.
The problem is:
supervise tcpserver qmail-popup 21 | {some logger}
This tcpserver opens stderr to print its log messages and opens a pipe to
stdin-stdout for qmail-popup's connection. In fact there isn't a way to do
logging right now.

Try commenting out line 91 in qmail-popup.c:
91 /* if (fd_copy(2,1) == -1) die_pipe(); */
92 close(3);
93 if (pipe(pi) == -1) die_pipe();
94 if (pi[0] != 3) die_pipe();
95 switch(child = fork()) {
96
Now checkpasswords and qmail-pop3d's SDTERR should go where tcpservers
STDERR
goes. Set a environment variable in qmail-popup, say LOGID to provide
a session wide unique tag to use in the popup - checkpassword - pop3d
pipeline.

If you run this program from command line, 0,1,2 are open. If you run from inetd, it dups 2 and 1 fom 0 (eg. 2 is alive). Tcpserver does a good emulation of command line.

If you will patch checkpassword/pop3d to log to STDERR, you will no longer be able to run them from inetd, because the log messages would be redirected to the mail client. The same with qmail-smtpd. I guess this is one reason qmail-smtpd does no logging at all. -- lars

But you should use tcp-env to run qmail-popup and you should open a pipe to a logger (esp. the stderr fd) which can be specified in command line.

Or, it can be called from a trivial wrapper that does the dup for it. actually, what about a syslog solution? i tried adding a syslog() call to checkpassword, but when i did that it stopped working for some reason (compiled fine, but authorization failed for everyone). i just want something similar to cucipop logging...for successful connects, it shows the username, how many messages they have (and size), and how many they downloaded during their POP session. that would be cool! -dan `--- dan peterson [ [EMAIL PROTECTED] ] http://erinyes.net `-- network engineer, digitaldune networks -- yuma, az `- (520) 344-1110 -- http://www.digitaldune.net
qmail-popup . Help me please
hi, I don't know from where to begin ? I even rewriten the checkpassword (Perl, based on auth against Radius server but with stripped Radius part). SO, I get the ".. $HOME/Maildir" error. If I substitute the "Maildir" in /etc/rc.d/init.d/qmail-pop3d.init with the real directory all is working fine, but the problem is that the dir must be different for every user that initiates POP connection, but I know his name only when the "tcpserver" executes "qmail-popup" i.e. impossible to be included in qmail-pop3d.init. The other tries I've made : with my changed script all is working fine if I execute it directly from console i.e. : [root]# qmail-popup myhostname passpass or [root]# qmail-popup myhostname passpass qmail-pop3d or [root]# qmail-popup myhostname passpass qmail-pop3d /mail/digicom-bg/xxx no matter (passpass is my variant of checkpassword) . but when the script is executed from "tcpserver" i.e. : [root]# telnet localhost 110 mostly I get ... "Connection closed by foreign host". And as it seems "passpass" is never executed (I have at the begining of the script writing to a test file, but nothing is written in it if passpass is executed via network i.e. passpass is not started but can track why) I can't use checkpassword 'cause I'm with shadow. Please help me I'm insane here, I know I'm missing something subtle. PS. Ooops another thing, when I start /etc/rc.d/init.d/qmail-pop3d.init start I get : hard error Starting qmail-pop3d .... done. and it is really started, when I make "telnet localhost 110" qmail-popup is invoked normaily, but after that "Connection closed by foregn host".. = [EMAIL PROTECTED] =
qmail-popup/checkpassword information
Where can I find out exactly what the gazintas/gazoutas are for checkpassword? I need to use a non-standard user/password file, and have to modify a login program to work for the pop logins.

Re: qmail-popup/checkpassword information
Look at the second paragraph of http://www.qmail.org/top.html#checkpassword I had hoped this was documented somewhere... I'm a microcontroller assembly language programmer, I have conceptual problems with a language that has no test-and-branch instructions and seems to consist mainly of the shifted top row of the keyboard. Oh well, time to dust off the trusty old KR book and go reinvent the wheel. Thanks for the pointers, I'll blunder through. Mark Bitting
