Ping (and I think traceroute, also) use snmp.  The default snmp ports are 161 and 162.

I hope this is what you were looking for.  If not, just reject this answer with a clarifying comment.

 

by: bbaoPosted on 1998-08-18 at 12:20:42ID: 1560489

I don't think so. Ping uses ICMP echo to request remote machine, not SNMP.

 

by: mrboboPosted on 1998-08-19 at 01:23:22ID: 1560490

Unfortunately I am not looking for the snmp ports, I am trying to find out what socket ICMP is on.....

You cannot ping outside your LAN through a MS Proxy Server.

MS Proxy Server will only pass TCP/IP and UDP.  It will not pass ICMP.

Go to

Here is an excerpt from MS Knowledge Base:

Application Issues (Browsers, RealAudio, etc.)

Does PING work through the Proxy Server?

No, ping uses the ICMP protocol to communicate. Proxy only supports TCP and UDP packets. Ping will resolve the DNS name but go no further. For example:

D:\>ping www.microsoft.com
Pinging www.microsoft.com [207.68.137.36] with 32 bytes of data:

Reply from 157.58.96.1: Destination net unreachable.
Reply from 157.58.96.1: Destination net unreachable.
