Hello All, I am thinking about using a linux server as a T1 router. I have searched the list, but have not found a discussion about what I''m trying to do. I have a situation where the Cisco router I''m using will not handle the additional bandwidth I added recently. Unfortunately, I cannot afford the Cisco unit that will. I would like to know if anyone has successfully done this. I have been looking at the Sangoma T1 cards. Would anyone be so kind as to share their experience in this area. Any advice would be much appreciated. Thanks, -G _______________________________________________ LARTC mailing list LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/cgi-bin/mailman/listinfo/lartc

Consider if you will that there are people using Linux to filter / bridge / rate limit / you name it with gigabit network interfaces, so I don''t think the 1.5 Mbps that a T1 will present will be a problem at all. My only concern would be in which card you choose and what sort of interface it presents to the system in addition to what sort of management tools you have available. I would recommend that you try to stay away from proprietary vendor provided drivers. Not that they will not work, but how many different kernel versions will they support? Will you be able to do what you want to do with it down the road, or will you be locked in to a specific configuration? Just my $.02 worth. Grant. . . .
Hi, I do not have experience with running a linux router with a T-1 card in it, but I _do_ run a linux box which serves as an egress device and provides policy based routing across three different ISPs using source addresses.... This network has about 1200 workstations and uses around 30 different Class C networks.. iproute2 provides a nice way of allocating Internet traffic generated by all these machines across two different T-1s and a 3 Meg connection depending on where the traffic originates... and it runs on a standard desktop PC (i.e., cheap) with a couple of NIC cards in it... iproute2 also provides the ability to ''blackhole'' a particular host (or hosts) and deny access to the Internet for those who misbehave or become infected with one scanning virus or another... I am looking for a nice command line tool that I could run on this policy based router that would allow me to more easily identify misbehavers and machines with viruses... I have tried a few tools such as jnettop, iftop, iptraf, pktstat and darkstat, but while each does what it was designed to do fairly nicely, I haven''t yet found the tool I am looking for... Any suggestions out there??

Any advice would be much : appreciated. I can recommend the Sangoma T1 cards. I have been using the S508 (ISA) and S514 (PCI) models since 1999. These cards and the (open source) drivers and management software are easy to use. The company is responsive and supportive of their product. The Sangoma crew have worked over the years to contribute their drivers into the stock kernel, so it is likely (unless the card you choose is a newly released card) that your card will be supported by your default distribution of choice. The software management tools are provided by a separate package, including tools for configuring the (optional) onboard CSU/DSU and diagnosing the frames received by the unit. Best of all, I can report that I have only ever found one bug in working with their software and drivers, and this was a corner-case bug that they had identified before I reported it to them (several years ago). In short, the software and hardware is very reliable. -Martin -- Martin A. Brown http://linux-ip.net/
