cannot accept ftp from Linux

[Tonatiuh]

My HP-UX 11.11 server does not accept FTP logins from Red Hat Enterprise Linux 4. It shows the next error:

421 Service not available, remote server has closed connection
No control connection for command: Illegal seek

It can accept FTP logins from Red Hat Enterprise Linux 3 and from Windows.

Any idea?

That smells like a client-side bug. Have you checked for an update from RH?

[Tonatiuh]

Client is Red Hat Enterprise Linux 4 Update 2. This is the latest update.

[Vincent Fleming]

All the more reason to believe that it's a client-side problem... I would try an earlier version.

Good luck,

Vince

Software I am running on the Client requires RHEL4U2. I cannot try a lower version.

[Vincent Fleming]

Now that I think about it...

The Open Source community sometimes introduces new features, and then enable them by default...

You might want to check the release notes for that version of the FTP client, to see if there's anything "new" that's been added as a default. You should be able to disable features that are incompatible with older versions of FTPD.

You can try to find out what it's doing with the -d command-line parameter (debug mode) and/or the "debug", "verbose", and "trace" commands.

Good luck,

Vince

I meant you should try an older version of the FTP client, not the OS.

You should be able to download either source code or binaries from somewhere.

What is the RPM for the FTP client? I just know the RPM for the FPT server (VSFTPD).

in my linux box (Red Hat Enterprise Linux ES (v. 4 for 32-bit x86)) the ftp packages are :
gftp-2.0.17-5.i386.rpm (graphical client)
vsftpd-2.0.1-5.EL4.3.i386.rpm Very Secure Ftp Daemon
ftp-0.17-22.i386.rpm standard UNIX command-line FTP
sftp : openssh-clients-3.9p1-8.RHEL4.9.i386.rpm and openssh-server-3.9p1-8.RHEL4.9.i386.rpm

Do you have some firewalls between your hp-ux and linux boxes ? routeur/firewall ? on red hat sellinux active ? iptables rules ?
/etc/hosts.allow /etc/hosts.deny files ?
