Hello,

We are trying to implement ssh passwordless access in a small cluster
running Scientific Linux 5.2 on i386. However, it is only working (ssh no

password prompt) from the nodes to the server.

The /etc/hosts.equiv includes both the name of the server and the computi
ng
nodes.

The /etc/ssh/sshd_config was configured as follows:

HostbasedAuthentication yes
IgnoreUserKnownHosts yes
IgnoreRhosts yes


The outputs from the node n07 to the server meyer:

[rialzuga@meyer ssh]$ ssh n07 date
get_socket_address: getnameinfo 8 failed: Name or service not known
userauth_hostbased: cannot get local ipaddr/name
rialzuga@n07's password:
Mon Apr 27 13:06:22 CEST 2009
[rialzuga@meyer ssh]$


[rialzuga@meyer ssh]$ ssh [log in to unmask] date
get_socket_address: getnameinfo 8 failed: Name or service not known
userauth_hostbased: cannot get local ipaddr/name
[log in to unmask] password:
Mon Apr 27 13:07:01 CEST 2009
[rialzuga@meyer ssh]$


The output from the server to the client:

[rialzuga@localhost ssh]$ ssh meyer date
Mon Apr 27 14:40:41 CEST 2009
[rialzuga@localhost ssh]$


Any suggestion will be greatly appreciated

Ricardo
