7. Verify that the local host's address-to-name translation for the remote
host is correct by using the nslookup command.
8. Inspect the routers along the path to the remote host to determine
whether they have security features enabled that prevent you from
reaching the remote host.
If a file cannot be accessed using the rcp or rsh command, the
following message is displayed:
permission denied
Complete the following steps:
1. Verify that the user is intended to have access to the remote host.
The remote host might be intentionally preventing remote access.
2. Verify that the correct host and user definitions exist in the user's
.rhosts file on the remote host.
3. Verify that the /etc/hosts.equiv file is set up correctly.
4. Verify that the directory and file protection on the files to be copied
or the .rhosts file on the remote system are correct.
5. If you are using NFS, see the appropriate NFS documentation.
If the telnet command is not successful, there is a problem with the
Transport Layer (OSI Layer 4). Do the following:
1. Verify whether you have a problem with a pseudoterminal driver
(pty) on your system by issuing the ftp command to the remote
host. If the command is successful, there is a problem with a pty on
your system. Contact your HP representative. See “Reporting
problems ” (page 71) for more information.
2. Check the /etc/protocols file on both hosts to ensure that TCP
is installed and configured. Neither telnet nor ftp will work if
TCP is not configured on both sides of the connection.
If it is not, install TCP and issue the telnet command again.
3. Transfer a file to a different remote host on the network. Use the
netstat command to check for lost packets.
If network congestion does not appear to be the cause, contact
your HP representative. See “Reporting problems ” (page 71) for
more information.
If the connection terminates abnormally or a network application appears
to hang, complete the following steps:
1. Test the network to determine whether the problem is on the local
host, remote host, or a host on the path between the two.
