Try looking for a sniffer called Ethereal. It's under GNU license and works on windows and linux (100% free) If you have a small network, you can enable debugging on all ip traffic, but it's very risky... Arie

Hi there is no trouble adding as much secondary ip addresses - no need for subinterfaces... Arie

Hi You could try the rate-limit command (CAR): define an extended access-list for, let's say, http and ftp: access-list 150 permit tcp any any eq www access-list 150 permit tcp any any eq ftp access-list 150 permit tcp any any eq ftp-data then go to the interface: interface serial0...

Hi Try looking out for MRTG... although a bit more difficult to install, it's 100% free and gives you a lot of options Arie

Hi I have noticed the same thing... I think it some kind of a bug... I tried playing with the front panel where the small button is, and I don't know if it's related, but it stopped doing it... Also, I try not to use the console, but use telnet instead.. Arie

Did you check the speed/duplex settings? don't leave it on auto (switch & workstations)

I wouldn't take a 2500 instead of the 1600 - 2500 are very old routers, 2600's are much better - or maybe even you could get a 3620/3640 - they would be upgradable in the future (modular router) Arie

Hi A few comments on the example: add: service password-encryption enable secret <password> - would be used for enable mode line vty 0 4 password <telnet password> exec login end also, there is no use to use 4 DNS servers... I guess 2 are more than enough. another thing, why to buy a...

The last parameter is not a normal metric, but it is used to set something called &quot;administrative distance&quot; and should be used in 2 cases: 1. if you use only static routes, as a metric, to seperate 2 or more routes going to the same place, with different priorities (backup links...)...

Hi Visio has an additional CD for Networking support. I think it's a seperate package and works only with the enterprise edition of Visio... Arie
