SNMP on Wireless Access Point Linksys WRT54G

Hi, I'm new to linux networking, so sorry if a don't understand something.

I have a Linksys WRT54G Wireless Access Point. It has a linux firmware
(Satori 4.0 from www.sveasoft.com). Well, it support SNMP, and I read
that this is a protocol to monitorize network conection.

I want to monitorize users bandwidth, displaying "current bandwidth",
"total bandwith", and others. Can I get this with SNMP?.

Firmware support SNMP, but I will have to install a SNMP client in my PC
that really is who get me all data?

By other way, we (wifi comunity) have problems with routers routing.
They (linksys) loss routes and have to set it manually. We thing Wifi
conection fail and then "set" the route as no valid, delete it and don't
try it again. Can SNMP help me to detect this kind of problem?.

Thanks for replies. I hope can learn a lot of in this forum. I always
use linux, but only as desktop without network/internet conection.

Bye

SNMP is most likely already setup on the Linksys, but you should configure a
different community name, for security sake. If you want to monitor this
from a WinBlows machine, use PRTG - it's by far the BEST SNMP client out
there and is free for stuff like this. http://www.paessler.com/prtg
As far as your routing is concerned, I'm not sure what you mean, but SNMP
has nothing to do with routing.

I don't think you can pull the stats down to individual users. Also, I
thought Alchemy was the first release with SNMP support?

Correct.

Best place to ask these questions are at:

You can use SNMP to pull back the routes but you will need something
else to check those routes.

SNMP is propably not started by default on the router (not safe). So try to
scan port 161 to see if it is up.

Yes, use an MIB browser. An snmp-walk through the MIB-2 should give you a
feeling, what parameters are stored here. Bandwidth is for sure.

Yes

You can configure SNMP traps, that can inform you, when there are changes in
the routing table.
I think you can even configure the routing table with SNMP, but you
definetly should not. The SNMP communitiy string (password) is always sent
in plain text, so it is no problem for people in your network to figure it
out. Don't forget to change the community strings, they are always set to
'public' for read access and 'private' for write access.

I have a Linux client, Suse 9.1. Which client should I use?

Yes I usuallly ask here. But can write in WRT54G forum, cause it is not
free. I wrote in Spanish forum.

Hi,

in package "net-snmp", you have a command line tool. You will sure find a
front end for it, if you need it. On my system, it is installed by default.
