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: [rialz...@meyer ssh]$ ssh n07 date get_socket_address: getnameinfo 8 failed: Name or service not known userauth_hostbased: cannot get local ipaddr/name rialz...@n07's password: Mon Apr 27 13:06:22 CEST 2009 [rialz...@meyer ssh]$ [rialz...@meyer ssh]$ ssh rialz...@192.168.0.7 date get_socket_address: getnameinfo 8 failed: Name or service not known userauth_hostbased: cannot get local ipaddr/name rialz...@192.168.0.7's password: Mon Apr 27 13:07:01 CEST 2009 [rialz...@meyer ssh]$ The output from the server to the client: [rialz...@localhost ssh]$ ssh meyer date Mon Apr 27 14:40:41 CEST 2009 [rialz...@localhost ssh]$ Any suggestion will be greatly appreciated Ricardo
