[mrtg] Re: Round trip time between distant routers

Wed Sep 4 01:11:19 MEST 2002

That's true, but I only use this on internal WAN routers, and I use SNMP
access lists restricting only the management stations IP address from having
SNMP access. If this isn't secure enough, then it may be better placing
management PC's at each site and have them use something like ping-probe.

All that is fine. But if you are slightly conscious about security of the
whole thing then perhaps enabling of snmp rw on devices are probably not
advisable. For instance if someone does grab hold of the snmp rw (which gets
sent in clear in any case), then more configs can be changed then just the
welcome message without logging onto the router. just through snmp sets.

*shrug*, depends how security conscious the whole setup is.

If you need some help, email me off line. 

I've been able to get this to work across various platforms and IOS
versions, but you need to be aware that some IOS versions suffer from memory
leaks due when rapid snmp sets and gets are processed. I've got this working
nicely now, but sing out if you need a hand.
