Portslave stuff for Linux

Portslave 1.16

It has moved to: portslave @ sourceforge

The mailinglist archives used to be here

This is the OLD documentation:

I've written some software that enables us to use Linux boxes on the Cistron Network as RADIUS compatible terminal servers, so we don't need to buy those expensive Livingston boxes..

What it does:

Initializes the modem and waits for a RING. Your modems don't need to be in auto-answer mode. You also don't need a getty.
When a connection has been made, portslave sends "login: " and expects that someone logs in. This data is sent to a RADIUS server on the network to see what protocol to start.
Portslave autodetects PPP packets at the login prompt and switches to PPP mode if needed.
Auto-detect PPP mode uses PAP authentication, also through RADIUS.
Protocols that can be executed are SLIP (built in), rlogin, local (shell) login and PPP. A RADIUS accounting packet is sent to a RADIUS server at startup.
When the session ends, another RADIUS accounting packet is sent.
You can specify separate servers for Authentication and Accounting. You can also specify secondary servers for both. All of this can be specified on a per-port basis.

This software has been in production use for a couple of months on all our POPs now and works fine. If you want you can read the README file for portslave. The latest version of portslave can also be found on our FTP server .

ripd 0.02

This is old software - I wrote it in 1996 or so, and I don't think anyone has any use for it in the 21st century. It's old, unsupported, but I'm leaving it here for software archeologists

Since there is no good routing daemon for Linux (maybe gated - but it's big, buggy and hard to understand) I wrote a simple RIP announcer to announce routes to dialin IP numbers that are not in your ethernet network. We redistribute this info into OSPF on the nearest Cisco router, so that we can offers POP independant static IP numbers.

tacp2rad 0.1

This is old software - I wrote it in 1996 or so, and I don't think anyone has any use for it in the 21st century. It's old, unsupported, but I'm leaving it here for software archeologists

We bought a Cisco 4000M for ISDN30 (PRI) access, and what do you think - it didn't support RADIUS (well, the -p image does but it was $1000,- more expensive). It does support TACACS+, though. So I wrote tacp2rad. This daemon sits between a TACACS+ client (a Cisco access server) and a RADIUS server, translating Authentication, Authorization and Accounting requests.

Probably by now it's better to just the the -p image. I'm leaving this code around as sample RADIUS and TACACS+ code for anyone who's interested in such things.
