Cannot rsh/rlogin on woody through NIS
Hi,
What's the deal with the woody versions of rlogin / rsh?
Although nis is working wonderfully, that's
node01:~# ypcat netgroup
(borg,,) (node01,,) (node03,,) (node04,,) (node05,,) (node06,,) (node07,,) (node08,,)(node09,,) (node10,,) (node11,,) (node12,,) (node13,,) (node15,,)(node16,,)
(node18,,) (node19,,) (node20,,) (node21,,) (node22,,)(node23,,) (node24,,) (node25,,) (node27,,) (node28,,) (node29,,) (node30,,) (node31,,) (node32,,)
(node33,,) (node34,,) (node35,,) (node36,,) node01:~# ypcat passwd
[passwd dump]
....
works, I can't login to nis slave machines. Is this because of login?
or because of rsh itself or perhaps even PAM, do you have any idea?
:(
The same setup used to work on potato, so might this be related
to the wonderful new glibc?
The setup is very simple. This is a beowulf comprised of 1 master and
32 slave nodes. rsh/rlogin works across nodes, each node has others
listed in .rhosts
exa@borg:~$ cat .rhosts
+@faiclients
Now, the following happens when I try to do it
exa@borg:~/public_html$ rlogin node01
Password:
Login incorrect
login: rlogin: connection closed.
exa@borg:~/public_html$ rsh node01
Password:
Login incorrect
login: rlogin: connection closed.
exa@borg:~/public_html$
The authentication log on node01 (/var/log/auth.log) is as follows:
Nov 18 17:49:09 node01 pam_rhosts_auth[9285]: allowed to exa@borg as exa
Nov 18 17:49:09 node01 in.rlogind[9285]: PAM authentication failed for in.rlogind
Nov 18 17:49:10 node01 PAM_unix[9286]: check pass; user unknown
Nov 18 17:49:10 node01 PAM_unix[9286]: authentication failure; (uid=0) -> exa for login service
Nov 18 17:49:13 node01 login[9286]: FAILED LOGIN (1) on `pts/1' from `borg' FOR `exa', Authentication service cannot retrieve authentication info.
Nov 18 17:49:18 node01 pam_rhosts_auth[9287]: allowed to exa@borg as exa
Nov 18 17:49:18 node01 in.rlogind[9287]: PAM authentication failed for in.rlogind
Nov 18 17:49:19 node01 PAM_unix[9288]: check pass; user unknown
Nov 18 17:49:19 node01 PAM_unix[9288]: authentication failure; (uid=0) -> exa for login service
Nov 18 17:49:22 node01 login[9288]: FAILED LOGIN (1) on `pts/1' from `borg' FOR `exa', Authentication service cannot retrieve authentication info.
What the heck is this supposed to mean?
I'd really like to remove this PAM thing from my cluster :(
Thanks,
