Bug 75026 – Cannot log in in proftpd and after deleting all files in /var/run/proftpd/ everithing is OK for a while

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Ras Algeti 2004-12-20 02:31:50 UTC]

Sometimes when I try to login in proftp it closes connection as seen below:

> ftp XYZ.AB.CD.3
Connected to XYZ.AB.CD.3.
220 ProFTPD 1.2.10 Server (OrganizationName FTP Server) [XYZ.AB.CD.3]
User (XYZ.AB.CD.3:(none)): user
Connection closed by remote host.

It occurs once in one or two days. 
In /var/run/proftpd/ have some files, I've delete them and ... Yes! I can login again! ;)

# ls -l /var/run/proftpd/
total 8
-rw-r--r--  1 root root 2232 Dec 20 09:38 proftpd.delay
-rw-r--r--  1 root root 1492 Dec 20 12:04 proftpd.scoreboard
srwxrwxrwx  1 root root    0 Dec 20 12:04 proftpd.sock

Version of proftpd is:
# proftpd --version
 - ProFTPD Version 1.2.10

This problem is only in this version of ProFTPD. I have no problems with the previous version (1.2.9 I think...). And after emerge -uvd wolrd it starts. I updated one gentoo box two weeks ago, and the problem occurs there. A discover that when delete these files in /var/run/proftpd/ everything is fine for about one day. Last week I update (emerge -uvd wolrd) another gentoo box and problem occurs there too :)

Reproducible: Sometimes
Steps to Reproduce:
1.ftp some.host.tld
2.And if you recieve "Connection closed by remote host." (or similar) after typing username then you've already reproduced the problem :)
3.

Actual Results:  
What happened after you performed the steps above?
"Connection closed by remote host." happened...

Expected Results:  
I think it will be nice if I can type password too, and if it is possible to log
in proftpd server. :)

I'm seeing this same behaviour. Vitals:

The only file that I need to delete to make it work again is /var/run/proftpd/proftpd.delay - and restart the server. The file is recreated after restart, and the server works again for a little while - less than 12 hours, since I fixed it last night and it was broken again this morning.

I have no idea what the file is for. Its contents are binary.

[Comment 3 Eric Paynter 2005-01-23 19:37:24 UTC]

Workaround: a little digging found that the file I was deleting was a part of the delay engine. Adding "DelayEngine off" to my conf file has made the problem go away.

[Comment 4 FieldySnuts 2005-02-17 08:35:43 UTC]

Eric,

I am facing this same problem this very moment.

Where exactly did you add DelayEngine off? wherever I put it, mod_delay still tries to look for the Delay Table. Pointing it at /dev/null still has it looking for /var/run/proftpd/whatever , which it definatey should not be doing since DelayEngine is off!

Using 1.2.10-r1.

[Comment 5 FieldySnuts 2005-02-17 10:02:48 UTC]

This is likely related to this bug:

http://bugs.proftpd.org/show_bug.cgi?id=2540

I had to edit the 1.2.10-r2 ebuild to not attempt to build mod_delay to get around the problem. Disabling mod_delay according to the instructions will not work.

[Comment 6 Gustavo Felisberto (RETIRED) 2005-02-17 12:46:09 UTC]

Can you please look at my notes at http://bugs.gentoo.org/show_bug.cgi?id=75072#c11 and try the ebuild i provided to see if it works ok.

[Comment 7 Gustavo Felisberto (RETIRED) 2005-03-02 15:40:24 UTC]

Well, all seems ok now with 1.2.10-r3 with no mod_delay in portage, i'm closing this.
