I'm trying to use snmpwalk to look at other machines, but I can't get a response. It keeps timing out. It can see itself, though. I haven't had this problem with other machines and I don't know what's different. Suggestions? -------------- next part -------------- An HTML attachment was scrubbed...

Maybe there is a firewall on one or more of the machiens involved? What does ethereal (or similar) tell you about the communications on this machine versus working machines? Regards, Greg

Make sure the one on the target machine allows it to respond. -- Les Mikesell lesmikesell at gmail.com
It will respond from another machine (WinXP). What port should I open on the box trying to do the snmpwalk? --Todd -----Original Message----- From: centos-bounces at centos.org [mailto:centos-bounces at centos.org] On Behalf Of Les Mikesell Sent: Friday, September 23, 2005 2:33 PM To: CentOS mailing list Subject: Re: [CentOS] Reading SNMP on other machine On Fri, 2005-09-23 at 09:15, Todd Reed wrote:> I'm trying to use snmpwalk to look at other machines, but I can't get > a response.
