By assigning specific port, I can open this port permenently on my firewall. Otherwise, I have to add the port every time on my firewall's trusted ports after ypserv is restarted. I tried the "-p port" option, but it failed to assign ypserv a specific port. When I run "rpcinfo -p localhost" to check, it seems ypserv always receives a random port from portmap. Version-Release number of selected component (if applicable): ypserv-2.13-5 How reproducible: Always Steps to Reproduce: 1. start ypserv with -p option at startup to specify the port: /etc/init.d/ypserv start -p 1000 or 1. edit /etc/init.d/ypserv file and add "-p 1000" in the "start" section. Actual Results: run "rpcinfo -p localhost" to check, it seems ypserv always receives a random port from portmap: #rpcinfo -p localhost |grep ypserv 100004 2 udp 798 ypserv 100004 1 udp 798 ypserv Expected Results: "rpcinfo -p localhost" should show ypserv with the port I started with (for example, in my case here, 1000). Additional info:
Can you provide the output of 'ps -eaf | grep ypserv' & 'netstat -tnlp'.

The problem you're having is that ypserv is not being run with the '-p 1000' option. Running '/etc/init.d/ypserv start -p 1000' will not run 'ypserv -p 1000' it will only run the ypserv init script (with the options specified there). The best thing to do is add the following line to /etc/sysconfig/network YPSERV_ARGS=-p 1000 Then run 'service ypserv stop', then 'service ypserv start'. Let me know how that works.

Yes, it is working now!!!! Two points 1. The line you give won't work until double quote is added to "-p 1000": YPSERV_ARGS="-p 1000" 2. So the man page of ypserv should be updated :) Thank you very much!!! You are great! This issue can be closed.

This issue can be closed. I would like to know the solution to "ypbind": how to bind ypbind to a specific port? I tried with this line in /etc/sysconfig/network (change your YPSERV variable to YPBIND), but it doesn't work: YPBIND_ARGS="-p 1001" On my NIS client machines, I also need to filter the ypbind port through my firewall to allow nis client connection to nis server, right? Correct me if I am wrong :) Thanks a lot.....
ypserv & ypbind use rpc (port 111), so there is no need to specify a port for ypbind.
