Kerberos

Tonatiuh — Tue, 08 Mar 2005 17:28:41 GMT

Red Hat Enterprise Linux 3.0.

I have two servers where I plan to install Oracle Database software.

How can I deactivate or deinstall kerberos so that it does not try to work when RCP?

[oracle@rac1 oracle]$ rcp /tmp/rcptest Nodo2:/tmp/rcptest-int
Trying krb4 rcp...
trying normal rcp (/usr/bin/rcp)

Additional comments:
1) This is a private LAN which only have the two servers that I need to perform RCP from one to each other. So that it is secure by its isolation.
2) The Oracle software I am using connot work with SSH.
3) This comunication (usnign RCP) must be as fast as possible to have a good performance of my Oracle Database installed in thiw pair of servers. This is the reason because this failed try with kerberos could be bad for my performance.

Check to see if the rsh rpm installed two binaries called rcp, one in /usr/bin/ and one some place else:

rpm -ql rsh rpm

I vaguely remember they put the kerberized binaries in the path before the non kerberos ones.

There may also be a switch according to the man page:

-K turns off all Kerberos authentication

I only see one:

/usr/bin/rcp

If you do a "type rcp" you will see that you are calling the Kerberised version. Try calling "/usr/bin/rcp" directly.
