Monitoring masq'd hosts

Monitoring masq'd hosts

Post by fuh » Mon, 10 Jul 2000 04:00:00



I have a linux box connected to net via cable.
Several win PC's are masq'd behind it.

I would like to:
(i) Monitor how much each win host has downloaded/uploaded.
(ii) And be able to limit the bandwidth available to each host.
(iii) If possible set a quota for each host.

Any suggestions?

iptraf or nacctd, according to taste.

Quote:> (ii) And be able to limit the bandwidth available to each host.

/usr/src/linux/Documentation/networking/shaper.txt

Quote:> (iii) If possible set a quota for each host.

Can't think of an easy way around that.

You might be able to wangle it by writing a script that checks what each
host has used with nacctd, then ipchains them until they pay up, or
something :)

1. IP Masq'd Workstation to connect to IP Masq'd Workstation

I have setup my Linux Box with IPMasq. Everything runs fine from my win box
behind the proxy. Now I just encountered a problem. I have tried to connect
to an ftp server that is behind NAT server which are both on winboxs

| Win workstation |
| Win         |---------|    Linux      |------------|    Sygate

|                 |             |   Proxy      |   Internet    |    Win box
|              | server                |
------------              -------------                   -------------

I can't seem to connect to the FTP even when the FTP Client is set to
passive mode. Does anyone know whether there is anything I can do on my side
of the connection such as reconfiguring my Linux Box to fwd properly?
