Try traceroute to your machine from other machines and see the path it follows, /bin/traceroute <your IP> Also, try /usr/sbin/tcpdump -n (add -i <interface> also to listen to a particular interface ) on your machine while the other machine ping to your machine. You will see repetitive messages like the following in your machine when ping works. 14:14:37.116336 IP 192.168.5.1 > 192.168.5.3: icmp 64: echo request seq 5 14:14:37.116473 IP 192.168.5.3 > 192.168.5.1: icmp 64: echo reply seq 5 try whether you get any hints from the output, especially from the IP address. -- regards, Ashok. -- redhat-list mailing list unsubscribe mailto:redhat-list-request@xxxxxxxxxx?subjecthttps://www.redhat.com/mailman/listinfo/redhat-list
