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.
telnet command
successful?
NO
YES
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 83)
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 83)
for
more information.
Connection
stays up?
NO
YES
If the connection terminates abnormally or a network application
appears to hang, complete the following steps:
1.
Confirm that the NIC is properly configured.
Make sure the cabling from the local host to the network is intact
and properly connected.
2.
3.
Test the network connectivity between the link aggregate and
other hosts on the same subnet using the
ping
command.
4.
Verify the link aggregate membership. See the steps for Link
aggregate enabled?.
5.
Verify that there is an IP address configured on the link aggregate
and that the IP interface is up with the
ifconfig
command. If it
is not up, bring it up with the following command:
# ifconfig interface-name up
Test the connection with the
ping
command.
6.
Test the network connectivity between another interface on the
server and other hosts on the same subnet. If this fails, there is a
network problem.
7.
Examine the traffic over the link aggregate. Heavy traffic might
cause the LACP system to lose communication, which can cause
the link aggregate to lose connection with other ports or cause the
LACP link aggregate to go down temporarily. Reduce the traffic
on the link aggregate.
