(usr-tc) SNMP limitations on NMC's
What's the plan on fixing the NMC's so they'll handle SNMP PDU's larger than 1500 bytes (or whatever it is around that number that is the actual limitation)? Now that I'm starting to write some SNMP scripting...I'm *quickly* running into this limitation, and its gonna really suck to have to code around it. Can the NMC's IP stack not reassemble or something? Isn't that terribly broken? -- Jeff McAdams Email: jeffm@iglou.com Head Network Administrator Voice: (502) 966-3848 IgLou Internet Services (800) 436-4456 - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

I thought they fixed this in NMC 6.x...? In 5.x and earlier it would actually kill the whole IP stack on the card and you had to reboot the NMC. I thought I tested 6.1.7 and it didn't kill the card anymore. (They finally fixed all those off-by-one Radius accounting bugs too.) Anyway, the reason I have that ma_snmp.pm wrapper around all my SNMP code is because there's a workaround for that bug in there, among other things... It takes the array of OIDs you're going to query and breaks them up into chunks small enough to make the card happy, then reassembles the responses.

Well...it is fixed so that it doesn't kill the Agent anymore. But they didn't fix it enough so that you can get responses to your large get. Your get still times out...but at least you don't have to go back and reboot the card (which is particularly difficult to do when you don't have an functional SNMP Agent on it) now. Oh...and it didn't seem to kill the whole IP stack for me...the card was still pingable...just no SNMP response from it...like it killed the agent.

Yeah...I've been writing code today to do essentially that...at least proof of concept code so I know how to do it...maybe now that I've worked out the details of what I have to do to work around this crazyness I can get back to actually writing useful code. :) -- Jeff McAdams Email: jeffm@iglou.com Head Network Administrator Voice: (502) 966-3848 IgLou Internet Services (800) 436-4456 - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.

Has anyone else tried to connect the new Dreamcast game machine to their TC hub? It seems to be similar to a web TV box, but it should work from the local mail server as well as dial-up. I have a new customer who is having trouble getting connected and the error messages on my end show garbled passwords or last letter dropped. It sounds similar to a previous problem, but I don't recall the solution. We are running 1.2.60 on the DSP, 5.9.9 on quads, 4.1.59-6 on ARC and 5.5.5 on NMC.

the Dreamcast uses and HCF modem ... whoopie! Wonder if it's upgradable to later drivers?? ----- Original Message ----- From: Wayne Barber <barberw@tidewater.net> To: <usr-tc@lists.xmission.com> Sent: Monday, October 11, 1999 4:01 PM Subject: (usr-tc) Sega Dreamcast

I would assume the drivers are on the Internet CD. I wonder if Sega will be upgrading the CDs, and at what price?

I had to add 1 comma at the end of the number. Wayne Barber wrote:

just curious as to why someone would attach this Dreamcast to a TC unit...

This issue was visited awhile back and, as I recall, the solution works for WebTV as well as Dreamcast units; set ppp authentication_preference PAP set ppp receive_authentication PAP change Framed-Compression in Radius from None to Van-Jacobsen-TCP-IP HTH, -- Kirk Mitchell-General Manager mitch@keyconn.net Keystone Connect Unlock Your World Altoona, PA 814-941-5000 http://www.keyconn.net - To unsubscribe to usr-tc, send an email to "majordomo@xmission.com" with "unsubscribe usr-tc" in the body of the message.
