Unhappy Problem connecting to RedHat Linux7.3 using FTP

Hi gurus,

2 days back we installed Red Hat Linux 7.3 on a Intel Xeon machine (multi processor).


When i try to ftp to the server from any client iam getting the following error :
530 Must perform authentication before identifying the USER.
Login Failed.

If FTP from the same machine the following error msg. appears :
Connected to <machine IP>.
220 <machine name> FTP server (Version 5.60) ready.
334 Using authentication type GSSAPI; ADAT must follow
GSSAPI accepted as authentication type
GSSAPI error major: Miscellaneous failure
GSSAPI error minor: No credentials cache found
GSSAPI error: initializing context
GSSAPI authentication failed
334 Using authentication type KERBEROS_V4; ADAT must follow
KERBEROS_V4 accepted as authentication type
Kerberos V4 krb_mk_req failed: You have no tickets cached

The server accepts login from users FTP, GUEST, ANONYMOUS but not from any other user.

Telnet is working.

We are struggling hard on this issue.
Thanks in advance for all the help.

Check for the path for ftp. I had same problem RH9 and make sure the path is /usr/bin/ftp , not /usr/bin/kerberos/ftp. Hope this helps.

2 things.

1. DO NOT use telnet, everytime a remote user logs in via telnet, their username and password get sent across the network in plain text and any downloadable packet sniffer can display that information in an easy-to-read format. Even linux comes with Ethereal and I've tested this before with Ethereal and it does display that information plain as day. USE ssh instead.

2. If you have sshd running (which is like default these days) you can then use sftp (secure ftp). Try to ftp to port 22 on the server machine using the SSH protocol. Windows machines dont come with SSH clients by default so may have to find a free download. If i recall correctly, FTP also send usernames and passwords across the network in plain text.

just my 2 thoughts. always be as secure as possible.
