nufw - NUFW User filtering gateway server

nufw [ -h ] [ -V ] [ -D ] [ -m ] [ -U ] [ -v[v...] ] [ -k keyfile ] [ -c certfile ] [ -a cafile ] [ -d address ] [ -p (remote) port ] [ -t timeout ] [ -T track_size ] [ -I ServerID ]

This manual page documents the nufw command.

nufw is the minimalist server, designed to run on the gateway(s) of the network. nufw is designed to run in conjunction with nuauth, the authenticating server. nufw receives network packets from the local firewall (on Linux 2.4 and 2.6, this is set up with the help of '-j QUEUE' netfilter target), and synchronizes with a nuauth server to check packet is authorized to travel through the gateway.

The design of the NUFW package lets administrator filter network trafic per user, not only per IP. This means you can now deal with different permissions for user A and user B, even if they work at the same moment, on the same multiuser machine. In other words, this extends firewalling criterias to userID, at the network scale.

Original packaging and informations and help can be found from http://www.nufw.org/

-h

Issues usage details and exits.

-V

Issues version and exits.

-D

Run as a daemon.

-U

Use UDP, unencrypted protocol for communication with the nuauth server. This is NOT recommended.

-m

Mark packets with UserID. This requires the wvmark POM patch applied to netfilter, and is necessary for per user QoS or routing.

-v

Increases debug level. Multiple switches are accepted and each of them increases the debug level by one. Default debug level is 2, max is 10.

-k keyfile

Use specified file as SSL (private) key file.

-c certfile

Use specified file as SSL (public) certificate file.

-a cafile

Use specified file as SSL certificate authority file. This parameter is optional.

-d address

Network address of the nuauth server.

-p port

Specifies TCP port to send data to when addressing the nuauth server. Nuauth server must be setup to listen on that port. Default value : 4128

-t seconds

Specifies timeout to forget packets not answered for by nuauth. Default value : 15 s.

-T track_size

Ask regit :) Default value : 1000.

-I ServerID

Ask regit :) Default value : 12345.

Nufw was designed and coded by Eric Leblond, aka Regit (<eric@regit.org>) , and Vincent Deffontaines, aka gryzor (<vincent@gryzor.com>). Original idea in 2001, while working on NSM Ldap support.
