Question Pure-FTPd 421 Connection closed by remote host


I'm really baffled by this one...

I'm running openSuSE 11.0 on a 10-year old machine. I recently setup Pure-FTPd, primarily so I could have friends & family members send me large files, without having to use a third-party service.

When I first setup Pure-FTPd, I am using PAM authentication (in addition to UNIX authentication), which was what I thought was the source of the problems I was experiencing. However, the problem even happens with "virtual" users.

I can log onto the server without an issue & obtain directory listings, create folders, and download without any issues.

When I try to upload a file, I get a "Connection closed by remote host".

This is also happening from any PC on my home network, as well as the physical machine itself that is hosting Pure-FTPd (ftp localhost).

When I ftp to localhost, the error message has error code 421, followed by the "Connection closed" message.

If I was not having this issue with localhost, I would say that it was a network configuration issue.

Doing a netstat -tan shows the following for port 21
tcp 0 0 0.0.0.0:21 0.0.0.0:* LISTEN

As I mentioned, it is ONLY when uploading... I could understand if I couldn't issue any commands (what is really baffling is the creation of folders/directories works), but it is just on an upload.

I made myself a member of the ftp group, and that is the only group that the virtual users are set for.

Thoughts?

Thanks

Looking in the log, I think I found the problem, but don't know how to fix it.

"kernal: pure-ftpd[port]: segfault at [address1] ip [address2] sp [address3] error 6 in pure-ftpd[8048000+22000]"

Examples:
port: 9931
address1: bf784c80
address2: 0805423d
address2: bf784c80

port: 8710
address1: bf597aa0
address2: 0805423d
address3: bf597aa0

Thoughts?

Ok, so after some more digging, it turns out that it isn't just me who is having this problem... someone messed up the build that is in the OSS repo.

http://forums.opensuse.org/network-i...ml#post1835456

The link that Ben posted is now out-of-date. Here is the directory of the SUSE_Factory:
http://download.opensuse.org/reposit..._Factory/i586/

I just downloaded & installed using "Install Software" -- note: do NOT install with the "Install with YAST" option, as it'll go out & get the Repo version 9since it is newer).

Uninstall the Repo version before installing this one.
