Re: Monitoring bandwidth behind a router
 

The biggiest problem is if you are in an EX cable and Wireless area then you haven't got access to use MRTG. you can't eve ping it and do a docsis... NTL have it blocked due to security problems.

Re: Monitoring bandwidth behind a router
 

Has anyone found a program that will monitor Internet traffic with a LAN (Linksys Wireless-G router)?

I am in a ex-C&W area, with a STB, and a LAN. I've always used DUMeter which is nice, but it includes 'inside' LAN traffic as well as traffic going 'outside', which is going to screw up my log.

Has anyone found a good app that will monitor traffic going outside from my computer (and preferably the others, but i'll tolerate it from my desktop only), but ignore the general LAN traffic? I use RealVNC which is really bandwidth heavy so that does have a big impact on my log. I've poked around and searched, but I can't seem to see a solution for STB/ex-C&W people. I might be getting a SACM soon (providing they don't hit me with a new contract) for the speed upgrade, is it any easier with that?

Thanx.

Re: Monitoring bandwidth behind a router
 

It's probably been said before but your best bet might be to get an old 486 (mine from from the tip) and use that as a router. Try IPCop, that has MRTG built in.

One nice thing about this solution is that you can use it to get around all the NTL related cock-ups. With a Linksys router, very often the DHCP would run out and not automatically renew, killing overnight downloads or online games. I set up a cron script to automatically renew the lease if it was less than 6 hours, repeatedly every 10 seconds until it's over 6 hours again. You can also run a transparent web proxy and dns cache, which reduces your bandwidth use.

Compared to the Linksys, it can cope with things like eMule which opens 500 connections at a time. The Linksys tends to drop them randomly after a while.

I reckon the 486 costs about £2/month to run, and cost me nothing. I modded the PSU fan to run on 5V so now it's nice and quiet too. I'd look for a low end Pentium or Cyrix though, as the web interface is a bit slow on a 486.

Tip: If you are already using a Linksys or other router, try changing the routers MAC address to the same one as the WAN side NIC in your 486 and registering it with NTL first. Then, when you swap over to the 486, you won't have to register and everything will just work.

If you're using a WRT54g, why consider a 3rd party firmware? www.sveasoft.com it adds a load of features:

Local DNS Server
Static DHCP (thanks for Wumpus and Sveasoft forum for this patch)
Autorun Bash Shell Script (ABSS)
Restored Ping hack functionality
Transmit Power Hack Built-In (!!)
Antenna Diversity Selection
Support for DYNDNS Custom
Remote Wake On Lan Support
Added Support for 255.255.0.0 and 255.0.0.0 Lan Net Mask
Working Multi PPTP Passthrough
SNMP support
Latest BusyBOX installed
Worldwide Channel support 1-14 even in US release
Added Status page with uptime and CPU load info
Added more Server Profiles (Ident, MSN, VNC, et cetera) for Port Forwarding
Added Reboot Router/Service button (Administration) for soft reboot router OR manual reboot all Service
Fixed Linksys' problem with FTP Passive mode
Added support for ZoneEdit.com
Added Server Profiles for easy port forwarding w/ 20 templates

VPN features
------------
VPN (PPTP) server (Up to 1024 clients but max 5 due to RAM limit)
Support for WAN connect to Local PC behide WRT54G VPN
Support for VPN to WAN, using like a router VPN
Full Compress and Crypto mode, Faster/Better with full M.S 64/128 Bits Crypto
Full support for Windows 9x/2K/XP and Linux with PPTP Client

Added Telnet access to router- features:
-------------
Password protection (logon: root & password: same as router)
Turn on/off Telnetd service (Under Administration->Management)
Auto block telnet access from WAN to LAN

Including native SNMP and firewall monitoring via WallWatcher http://www.sonic.net/wallwatcher/

It works really well.

Re: Monitoring bandwidth behind a router
 

Ahh, cheers for that. I'm a bit worried though, if I change the firmware to a third party one, and something goes wrong (only half transfers/gets corrupted or something), is there a way to reset it (without going into the admin page, like a button) so if anything goes wrong I can go back to the original firmware instead of permanantly damaging my router?

Re: Monitoring bandwidth behind a router
 

Hmm, the reset button on the router. The base firmware is encoded into permanent ram and cannot be removed.

Re: Monitoring bandwidth behind a router
 

Ahh cheers for that guys :tu: :)

Re: Monitoring bandwidth behind a router
 

I've tried a number of the 3rd party firmwares on my 54g but always seem to keep coming back to the ligit one! - PRTG did work though I do remember - I think I was having some wireless (MAC Address) problems which is why I resorted to the offical linksys one again!

Re: Monitoring bandwidth behind a router
 

SNMP it's dead jim :(

Re: Monitoring bandwidth behind a router
 

So I noticed from the 207 emails today reporting snmp timeouts :-(

*sigh*
