synopsys dc install problem

[hover]

I have installed synopsys dc 2004 linux version on my RHEL AS3.0 OS. I modified my license file according to my hostname and my snpslmd path. Then I use lmgrd to start the license. But it reported "failure to open TCP port". So I try other TCP ports. However, it reported "TCP port already in use". I have tried several prots. The results are same. I don't how to solve it.

Try!!!
The variable SNPSLMD_LICENSE_FILE is point (path to license file).
Don't run lmgrd

Once you used lmgrd, shutdown the license server before you try it again.
