ftp taking too long for login prompt

K.C. Chan — Wed, 27 Mar 2002 23:00:01 GMT

Gurus I am trying to ftp to oscar.cdnow.com form my rehdat 7.x box, but I am having to wait for a very long time. I am guessing from the below message that it's to long because it's trying to authenticate with kerberos failed, "ftp -vd oscar.cdnow.com
Connected to oscar.cdnow.com.
220 oscar.cdnow.com FTP server ready.
---> AUTH GSSAPI
530 Please login with USER and PASS.
---> AUTH KERBEROS_V4
530 Please login with USER and PASS.
KERBEROS_V4 rejected as an authentication type
Name (oscar.cdnow.com:guessxxx):"

does any one have any ideas? Thanks.

I suppose you've already tried using:

ftp -u oscar.cdnow.com

? According to the MAN page, it disables the auto-authentication negotiation. It should speed the login up.

Stuart I've already tried that and it's the same resort. Is there a way to tell ftp to use the regular way of authenticating since the other end doesn't support kerberos_v4? Thanks.

Michael, follows the screen output from my casual attempt to login, first without any
arguements and then with the -u ((note I have RH 7.2 -- I think you are using 7.1, no?))

Note after the ftp> prompt in the second session, I had to type in "user" to send my username. During the second session my box did not attempt Kerberos authentication (verified by re-running with ftp -uvd ....)

Could you have been experiencing a transient routing problem?
