There are several players in the X2 server-side beta and AOL has announced an "X2 field trial" for their customers in 4 or 5 selected cities. Prepare yourself for 'less-than' 56k performance (gee, no surprise here). USR was under enormous pressure to release something as people were getting tired of all the ad hype and were demanding product. The Client product which released is an all new flash rom based external Sportster. Nothing else released (no upgrades yet).

--IMA.Boundary.603247758 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Content-Description: cc:Mail note part Yesterday in anticipation of the x2 chassis released, we moved the TOTALservice servers to another network with a faster internet link. Because of this, the ip addresses changed. Your DNS servers may still have the old ip address which of course will prevent you from being able to access the server by name. The new ip address is 207.24.160.20. You can point your web browser there or ftp directly using your TOTALservice username/password. -John >Subject: (usr-tc) X2?? Anyone?

I can't seem to find a good way to restrict ISDN via RADIUS. That is, anyone who can use the analog ports can use the ISDN ports. What am I missing? -- Pete XMission

Pete Ashdown <pashdown@xmission.com> writes: > I can't seem to find a good way to restrict ISDN via RADIUS. That is, > anyone who can use the analog ports can use the ISDN ports. What am I > missing? One way would be to restrict what ports that user is allowed to authenticate from. The ISDN Ports (I0->) show up in the RADIUS requests as high port numbers (I believe they start at 67), so you could disallow a user based on the port range. Or, you should also find a NAS-Port-Type attribute in the request, which can be used to distinguish the ISDN calls (values ISDN-Sync, ISDN-Async-V120 or ISDN-Async-V110) from analog calls. -- David

Hi All, Hoping that someone might be able to help me. We're installing several USR TC racks at present and I'm having a problem getting the modems to speak to the NETServer. I've got the modem DTE source set for 'packetBus', I've got the port enabled in the NETServer (set modem s60 active), and generally got all the other settings right (as far as I can tell). I can dial up OK, but never get a login prompt from the NETServer. 'show s56' shows the port as idle, even though there is a call on it. The port configuration is below. If I adapt the configuration I can telnet to the modem and configure it (although I normally use TCM for that). Any ideas? ----------------------- Current Status - Port S60 --------------------------- Status: IDLE Input: 0 Parity Errors: 0 Output: 0 Framing Errors: 0 Pending: 0 Overrun Errors: 0 Active Configuration Default Configuration (* = Host -------------------- --------------------- Can Override) Port Type: Login/Netwrk Login/Netwrk (Dial In) (Security) Login Service: PortMux PortMux Device Service: Telnet@6060 Telnet@6060 Modem Stat: READY ACTIVE Databits: 8 8 Stopbits: 1 1 Parity: none none Flow Control: None None Modem Control: on on HDLC Framing: PPP in modem PPP in modem SLIP Framing: SLIP in modem SLIP in modem Modem Presence: Modem is present Init Script: (None) Init When?: Never Hosts: default Terminal Type: vt100 Login Prompt: $hostname login: Login Message: Southern Internet Services - Hobart^ Dial Group: 0 TAP type: OFF OFF Regards, Bob Purdon, System Administrator, Southern Internet Services.

I'm running Radius 1.6/shadow on a Linux Box, and have my Quad modems configured for Login/Network (dialin). Radius is configured with a single Default (PPP) entry which uses the UNIX password file. When security is OFF, the TC Hub does what I call 'AutoPPP', it automatically differentiates between PPP and shell logins, without the need for any 'prefixes' or 'suffixes' to the username. (Which I am aware would require a patch to Radius 1.6) When security is ON, users can ONLY connect with PPP. Is there any way to get the TC-Hub (Netserver Card) to do the AutoPPP with security set on so I can get shell logins listed in the Radius Log Files? The userbase is about 700 users, and requiring users to use prefixes or suffixes will be a big headache. On another point, I'm going to the USR TC classes in Seattle, WA next week. Anyone have any comments about the classes? Thanks, Paul Schuh Paul@new-era.com

I do not understand your Framed-Route line--you are routing a single address with a metric of 2?? I use the following (with Livingston RADIUS) with no problem to route to a /27: username Password = "UNIX" User-Service-Type = Framed-User, Framed-Protocol = PPP, Framed-Address = <IP address in class-C that Netserver is on>, Framed-Netmask = 255.255.255.224, Framed-Route = "<IP of client's network> <same as Framed-Address> 1" This works well for modem routers (eg NT) that need to have an IP address for their modem port that is not on the same network as their Ethernet. Other routers (and Linux or FreeBSD) can be assigned an address within the client's network.

Lazlo, What is the rest of your setup like? Are you using Auto Response? How have you activated idle-timeout? Strictly by modem setting? As an alternative usually whatever Communications Server or whatever you are using behind the modem also should have this capability and you might find it works better or more reliably.

Brian, We use USR's Total Control Product but strictly in a management/configuration scope. I've note tried to bring in any of the accounting etc. Many of our measuring systems are done on unix with in house scripts. For our modem usage statistics we use unix scripts which go out and do a finger against our Cisco 2511s (Communications Servers) which the modems attach to. We do this once every so many minutes. Currently I think we look about 1 time per 10 minutes. Our modems have a 1 hour limit for usage on them also. We wrote perl scripts which condense and calculate the stats and then output them to some kind of a format that we can graph. It was quite a job and unfortunatly we are constantly being questioned about the validity of our stats. But my argument is that almost any measurement system works this way, periodically looking at the lines, either through SNMp queries or through some other method and basically they see how many lines are in use. Most all lose some kind of issue. Ours for instance cannot always tell when a line gets screwed up and either won't answer or gets inadvertently busied out. So we're trying to build safes into our system to let us know when modems may be screwed up and then either manuallly or automatically reduce the max available to account for that. Stats seem to be a tough issue for us. We've looked at alot of methods. USR's accounting package, I would have to see work for a while before I would depend on it. Their AutoResponse package I've not been overly happy with. I've seen cases where because so many events are taking place the response scripts appear to get lost, leaving modems in strange (unrecoverable) states and I'm not convinced that this wouldn't happen with their accounting packages either. Time will tell I guess. Our office is next to the Network Computing Magazine's lab and one kid that works for me works there, so he's trying to get it for an eval and if so I'll be looking over his shoulder on it. We also use tacacs authentication logs as a basis of use also. Once again this is unix based with home built scripts (usually perl) to condense the stats it collects.

I'm having trouble upgrading the modem firmware in my Netserver/16s. If for some reason an upload doesn't work, but the unit never responds FAILS or COMPLETE or similar...is there a way to reset whatever flag tells the nsmgr software that an upload is still "in progress"? Short of rebooting the box? It's in production, with ten users on it, and I don't want to kick them off....but even when I start a new Netserver Manager session, it seems to know that a previous upload hadn't completed.

With small subnets, like 29bits, I just map a 32bit entry for each of the individual routes.. at least that seems to be the only solution at the moment. Also, an entry of Idle-Timeout in the radius config (I'm speaking of the unix radiusd) does not seem to work at all.. this is needed because I need the average user to have a timeout of 15 minutes in the DEFAULT entry, and certain static users to have a timeout of zero.

--IMA.Boundary.705888858 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Content-Description: cc:Mail note part Pete, Correction on Todd's message. There are TWO ways of identifying ISDN vs. Analog. Method #1: Using the NAS-Port attribute (attribute #5 in RADIUS IETF spec), the RADIUS server can parse the value and identify the port source. All numbers 0-64 indicate an analog port, 65-66 indicate the Frame Relay ports, all numbers 67-131 indicate ISDN ports. This method works on all NETServers using v3.1 code or later. Method #2: Using the NAS-Port-Type attribute (#61 in the RADIUS IETF spec), the NETServer will send a field with one of five values, which include (0)Async, (1)Sync, (2)ISDN Sync, (3)ISDN Async V.120, (4)ISDN Async V.110, and (5)Virtual. The RADIUS server can then key off this field to determine if the caller is using either (0, 1, or 5)analog or using (2, 3, or 4)ISDN service. This method works on all NETServers using v3.3 code or later. Hope this helps.

It would be very useful to have a test or sample account created, either in radius or netserver configuration, such that dialup users would be able to log in for a PPP session but be limited to only the local network, or better yet, a specific IP or range of IP's. In this way they could test out their connection, and read up on information provided by a local webserver. How would this be implemented in (unix) radius configuration, or on the netserver card? - Lester

We are considering purchasing a Total Control MP/16 I-modem box and attaching it to the 16 async lines of a Cisco 2511 access server. I would be interested in corresponding with anyone who already has this type of setup. Especially helpful would be someone using TACACS+ for authentication. Thank you. tom blauvelt Thomas Blauvelt North Country Reference & Research Resources Council blauvelt@northnet.org 7 Commerce Lane Canton NY 13617 USA (315) 386-4569

We have recently purchased a basic Total Control System comprising Basic Chassis and 4 x 4 modem cards (total 16 ports) We are planning to use 2 x 8 port digiboards in a Windows NT 4.0 Server and RAS. Can anyone enlighten me as to which modem I should select from the various modems selectable under NT 4.0 ? e.g. A Basic courier or what? There does not appear to be a direct 33.6K driver for this particular modem and USR Tech Support are not returning e-mails. Any help would be appreciated. Regards

The machine was unreachable for a number of hours last night (I tried it probably from about midnight-4am EST). It wasn't a routing problem (at least not on a wide area) since traffic reached the local network where the machine is located. I expect it was just maintenance or some other problem with the machine. It appears to be reachable now. -- David

My TC ENH is reporting to radius that all session disconnects are lost-carrier when the are not. If I call in and hang up, then check the total control manager modem performance stats it shows that the sessions was lost because of a v42 disconnect command (the user asked to hang up) NOT a dropped carrier. Anyone else having this problem? Also, the TC is returning the property #26 and it isn't defined in the radius dictionary file. I even downloaded the latest radiusd and dictionary file. I tried adding it in myself and it didn't return anything that made sense to me. I tried changing the value to type string, ipaddr, integer and date. Thanks, Tom

If you have the capability I'd check for duplicate IP addresses. If that is not possible or is not a concern I'd check the setup information using the serial port. Chances are though USR is correct.

Dumb question (since you're probably right in front of chassis and would have noticed) but the hub status can also reflect a failure of one of the power supplies, which of course exist even if you don't have any other cards in slots 1-16. You could also check the self test status from the NMC - it might be that one of its own components (such as the UARTs used to drive the management bus to all the slots) has failed testing. Of course in such a case a swap is the right thing anyway. If you have an alternate NMC then swapping it in could help test chassis issues versus NMC card issues, prior to swapping the NMC via USR. -- David

Is there a netserver console command to show how many Sxx ports (quad modems) are available, or more accurately, online and prepared for a call? (The system might have more quad modems/ports than PRI lines to handle them) I'm finishing up a freeware utility that does a few different things, (disconnects duplicate logins, people over a certain idle or online time.. especially during prime time hours) and it would be helpful if the user wouldn't have to specify a maxport setting.. but instead it would be extracted from somewhere.

I did an AltaVista search on pmcom and pmwho.

We seem to be having rather poor UDP performance over a Netserver. The game players here are complaining. Could it be the "PPP in modem" command? Right now I have it set to "on". I couldn't help but wonder why the default is "off". Second, what packets count as activity with the Netserver? One nice thing I liked about the Annexes is that you could define activity with a filter. Any chance of this happening with USR? -- Pete XMission

Netserver - XLNT Switch - Cisco 7000 - XLNT Switch - Quake Server Not a lot of room for error in there. Especially since replacing the Netserver with Xylogics Annex fixes the problem.

In terms of latency you definitely want PPP framing in the modem to be on, since that let's the modem build up the entire PPP frame and then transmit it to the NETServer as a single unit. Otherwise, it has to come character by character and additional latency can be introduced in between the fragments. The default is off probably just for backwards compatibility I expect. One suggestion I would have is to be using the latest modem and NETServer code. Latency used to be quite poor through the modem<->packet bus<->NETServer path, particularly before PPP framing was supported in the modems. But even after that subsequent NETServer releases did offer improvements on that front. But beyond that there really aren't any tunable parameters. Also, for those players they may wish to disable (if they aren't already) compression in their modems since that adds significant latency at the modem level, perhaps more than at other parts of the system. Also, are you sure the performance issues are just between the player and the NETServer, or could they also be arising from elsewhere in the network path? I'm not sure about the packet activity question. -- David /-----------------------------------------------------------------------\ \ David Bolen \ Internet: db3l@ans.net / | ANS Communications \ Phone: (914) 789-5327 | / 100 Clearbrook Road, Elmsford, NY 10523 \ Fax: (914) 789-5310 \ \-----------------------------------------------------------------------/

Pete Ashdown <pashdown@xmission.com> writes: > Well, more latency than what was happening on my Xylogics Annexes and > external Couriers. Agreed, I think that combination will beat it currently. The NETServer packet bus path has gotten better over time, but it still adds more than I would like. However, I wouldn't expect it to deviate by a tremendous amount nowadays. I tend to get round-trip times for your average ping packet over a V.34 dialup through a NETServer to a locally attached Unix workstation of perhaps 125-150ms. That's with full modem compression and stuff. > Interesting, because since I switched it to off, performance seems to be > better. I haven't done any hard tests yet though. I'm going to try with > netperf tonight. That is interesting since I've normally gained 10-15ms at least by letting the modem handle the PPP frame. Unless something changed recently. Not sure. > Again, this is USR-TC vs Xylogics Annex, and it only seems to be affecting > UDP/ICMP traffic.

Especially since replacing the > Netserver with Xylogics Annex fixes the problem. Well, I do think the Annex will get you some gain over the NETServer, at least that's been my experience in the past, if latency is specifically what you are looking for. -- David

My understanding is that it does the PPP within the modem, thus freeing up the Netserver. Is this worth it? I mean do you actually notice a performance increase? What other advantages are there?
