Agent Install Error: "Unknown host" |
Problem: NetDirector agent does not install, giving an "Unknown host" error.
When running the installer in text mode, the output is:
[root@RHEL4-AS ~]# ./netdirector-2.8.d-agent-linux-installer.bin --mode text
Error: Error running script hostname : hostname: Unknown host
Press [Enter] to continue :
[root@RHEL4-AS ~]#
When run in graphical mode, the same error is shown in a popup:
Cause:This error occurs when the hostname of the system (output of the "hostname" command) is not included in the /etc/hosts file.
Solution:Add the current system hostname to the /etc/hosts file. You can display what is currently in the file by running "cat /etc/hosts":
[root@RHEL4-AS ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 rhel4as.emusoftware.com localhost
[root@RHEL4-AS ~]#
You need to edit the /etc/hosts file to include the output of the "hostname" commnand:
[root@RHEL4-AS ~]# hostname
RHEL4-AS
You can do this in your favorite file editor (vi, Emacs, kedit, kwrite) as the superuser (root, sudo, etc). In this example, the above file was modified to:
[root@RHEL4-AS ~]# cat /etc/hosts
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 RHEL4-AS localhost
[root@RHEL4-AS ~]#
Once this change is made, the agent installer should install the NetDirector Agent. |
