also the server is not ping-able with other server.
As vbe already said this is perhaps because you have no network connection. This can have a lot of causes (on the client side as well as the servers), nobody can help you there without a lot more information.

If you regain the etwork connection and the problem still persists: every user has 2 attributes, "login" and "rlogin", which can be "true" or "false". See the output of the lsuser-command:

Code:
root@lpar # lsuser -a login rlogin foouser
foouser login=true rlogin=true

"login" allows the user to login at the console (or - which is the same - via the HMC). "rlogin" allows the user to connect to the system via the network. Many ssh-configurations are done in a way they do not honour this rlogin-setting, so you might be able to bypass this if your system is poorly configured, but if everything is set up correctly you should be unable to log on via network if "rlogin" is set to "false".

I hope this helps.

NAME
rlogin -- remote login SYNOPSIS
rlogin [-8EKLd] [-e char] [-i identity] [-l username] [-p port] host DESCRIPTION
Rlogin starts a terminal session on a remote host host. Rlogin first attempts to use the Kerberos authorization mechanism, described below. If the remote host does not supporting Kerberos the standard Berkeley rhosts authorization mechanism is used. The options are as follows: -8 The -8 option allows an eight-bit input data path at all times; otherwise parity bits are stripped except when the remote side's stop and start characters are other than ^S/^Q . -i The -i option specifies the local user name to use for authentication with the remote rlogind server. This overrides the default which is the name of the user invoking rlogin. -l The -l option specifies the name of the remote user to login as. This overrides the default which is the name of the user invoking rlogin. -E The -E option stops any character from being recognized as an escape character. When used with the -8 option, this provides a com- pletely transparent connection. -K The -K option turns off all Kerberos authentication. This option has no effect since Kerberos authentication is not available in this version. -L The -L option allows the rlogin session to be run in ``litout'' (see tty(4)) mode. -d The -d option turns on socket debugging (see setsockopt(2)) on the TCP sockets used for communication with the remote host. -e The -e option allows user specification of the escape character, which is ``~'' by default. This specification may be as a literal character, or as an octal value in the form nn. -p The -p option specifies the port to connect to. This overrides the default which is login. A line of the form ``<escape char>.'' disconnects from the remote host. Similarly, the line ``<escape char>^Z'' will suspend the rlogin ses- sion, and ``<escape char><delayed-suspend char>'' suspends the send portion of the rlogin, but allows output from the remote system. By default, the tilde (``~'') character is the escape character, and normally control-Y (``^Y'') is the delayed-suspend character. All echoing takes place at the remote site, so that (except for delays) the rlogin is transparent. Flow control via ^S/^Q and flushing of input and output on interrupts are handled properly. ENVIRONMENT
The following environment variable is utilized by rlogin: TERM Determines the user's terminal type. SEE ALSO
rsh(1) HISTORY
The rlogin command appeared in 4.2BSD. BUGS
Rlogin will be replaced by telnet(1) in the near future. More of the environment should be propagated. Linux NetKit (0.17) August 15, 1999 Linux NetKit (0.17)
