Yes, I am very familiar with them: http://ifctfvax.Harhan.ORG/OpenSDSL/existing_cpe/netopia/dsu.html As that page explains, they are only pseudo-DSUs though. I much much prefer a true bit-transparent DSU: http://ifctfvax.Harhan.ORG/OpenSDSL/existing_cpe/xsb2000.html I have also designed and built an SDSL to EIA-530 DSU of my very own: http://ifctfvax.Harhan.ORG/OpenSDSL/OSDCU/ On the latter I have the hardware (the page above has a photo of the board), but the operational software (or firmware if you will) remains to be finished. > Though, I'm not sure they'd work these days, Only in the very limited geographic footpring of what used to be DSL.net - they are the last remaining semi-major operator of CM DSLAMs: http://ifctfvax.Harhan.ORG/OpenSDSL/megapath.html My big goal is to make my own DSU which I have just mentioned function as a Layer 2 converter (FRF.8 and friends) from Nokia SDSL/ATM served by Covad to HDLC. > nor do I think > they came in ADSL models either. I don't think anyone have *ever* used V.35 & friends with ADSL - probably because those who would want V.35 (i.e., people like me) would find ADSL morally offensive. :-) MS

Ethernet should be for LANs only; using Ethernet for WANs and PTP links is the vilest invention in the entire history of data networking in my opinion. My medium of choice for PTP links (WAN) is HDLC over a synchronous serial bit stream, with a V.35 or EIA-530 interface between the router and the modem/DSU. Over HDLC I then run either RFC 1490 routed mode or straight PPP (RFC 1662); in the past I used Cisco HDLC (0F 00 08 00 IP header follows...). My 4.3BSD router (or I should better say gateway as that's the proper 80s/90s term) then sees a PTP interface which has no netmask at all, hence the near and far end IP addresses don't have to have any numerical relationship between them at all. No netmask, no MAC addresses, no ARP, none of that crap, just a PTP IP link. </soapbox> MS

Using /31 for router links
by Seth Mattinen 23 Jan '10

23 Jan '10

In the past I've always used /30's for PTP connection subnets out of old habit (i.e. Ethernet that won't take unnumbered) but now I'm considering switching to /31's in order to stretch my IPv4 space further. Has anyone else does this? Good? Bad? Based on the bit of testing I've done this shouldn't be a problem since it's only between routers. ~Seth

Network Bandwidth Reporting Tool
by Isaac Conway 23 Jan '10

23 Jan '10

Oh mighty list, I am curious what tools you use to generate monthly usage and billing reports for your execs? I am not really looking for a RRD type solution, rather a page I can pull up and gives me the numbers (95p, cost, overage, etc.) for the past month. Copy and paste into a spreadsheet, job complete.... We are getting to the point where we have multiple datacenters and numerous uplinks and circuits for each, I find I am spending too many hours each month compiling data. I was thinking about writing some quick scripts to poll the router interfaces and put it to database, but I figured I would ask before re-inventing the wheel. Thanks in advance! Isaac

Anybody know a contractor that could quote on building out a quality server room in a facility in the Toronto area? Our executive want to know what it would cost to build a room for our expansion as opposed to putting the hardware into a co-lo facility. Off-line response would be fine. Thanks, Erik
