How to open a port?
 
I am running lmgrd on CentOS5, but it returns

Failed to open the TCP port number in the license.

The port is 27000, how can I open that port?

make sure the service is running, and listen on port 27000
open the port in the firewall.

How to check if it is running? I use system montor, I didn't found lmgrd in the list of process. But when I run 'lmgrd.rc start' it didn't return any error.

So do you think it is the problem of lmgrd? How and where I can upgrade/reinstall it?

repo 06-21-2009 12:02 AM
Code:
ps ax | grep lmgrd
to see if the service is running
Code:
telnet 127.0.0.1 27000
to see if the port is open

What can I tell from the following result?


8018 pts/1 S+ 0:00 grep lmgrd


Trying 127.0.0.1...
telnet: connect to address 127.0.0.1: Connection refused
telnet: Unable to connect to remote host: Connection refused

repo 06-21-2009 12:12 AM
that the service isn't running
Perhaps you can take a look at the config file from lmgrd
