    How to check whether NIM server ports are open or not. Actually from one of the NIM client I checked:

    telnet ip 69(tftp) I got connection refused.

    telnet ip 2049(nfs) it worked

    telnet ip 67(bootp) Connection refused :(

    Does this means that these ports are blocked?????????Firewalled?????

    Thanks & Regards,

    Hi, you can not telnet to UDP port, because it's not session oriented.
    Do netstat -an | grep -E '69|67' on your NIM server and if the ports are listening then you have firewall blocking these ports.
    Also, you have lsof -i udp or lsof -i tcp commands to check which process ID is openning what network connection.

    Check for nimsh/nimaux port entries are commented in /etc/services file...Normally these port numbers are 1508/1509 and 3901/3902. restart inetd after enabling them

    You can test this port functionality from nim master as below

    nim -o lslpp <nim client name> - this lists the lpp's installed on the client.
