FW: [USR-TC] RE: Dial-In Problem!!!!
by Kirti S. Bajwa 30 Jan '06

Hello: For the last few days I have posted the following question: ============ Please help. This problem is going on for the last 7 weeks without fixing. TC1000 1-HiPer NMC 2-HiPerARC 10-Hiper DSP We are a small ISP (400 customers). We have 2-ISDN-PRI lines for our customers to dial in. Our entire system looks like this: / / T1 to External Internet / CISCO 26XX Router | HUB 10/100 | ---------------------------------------------------------------| | | | | | NMC ARC1 ARC2 Web Authentication ----------- 3Com ------------ Server/Email | | | | | | | | | Customer Dial-In Our customers can dial-in, are authenticated and can access the internal web site (www.tibonline.net) and retrieve their email. But when they try to connect to any web site (outside our network) on the external net (such as www.yahoo.com) they time out with a message saying that "this page can't be displayed". We have changed the HUBs, RJ45 cables. We have the CISCO Router tested fine. Finally, I replaced the 3COM box with a backup box and the problem continues. Interestingly, we can access any Internet web site (www.msn.com, www.yahoo.com, etc.) from our internal network (over LAN) without problem. ============ Since posting the above message, we have received a number of responses. Charles suggested to see how the CISCO 2600 was assigning the IP addresses (or something similar!!). For the last two days, AT&T technicians has been working with me to look into the router. They have setup static address and have done number of settings without success. I have switched 3COM to a backup 3COM box. Following are new the IP address: NMC (Port 17) 12.21.237.240 ARC1(Port 15) 12.21.237.241 IP Pool: 12.21.237.48/31 ARC2(Port 16) 12.21.237.242 IP Pool: 12.21.237.96/31 The problem is that out Dial-In customers can dial-in, access the internal network (email, authentication, DNS, Web Servers) but can not access the external Network (www.msn.com) etc. I have setup a dial-up PC (Win XP Pro) to test. The first time I connected, the IP address assigned was 12.21.237.98. I could not access the external network. I tried to do a external trace from www.traceroute.org. Following are the results of the trace. -------- Call this TRACE-1 Testing the network route from EASYNEWS.COM to 12.21.237.98...

In TRACE-2 (outside network is connected & the dial-in connection works), the trace gets to my dial-in terminal (12.21.237.99). I have noticed couple of things in the above traces. In both traces, ARC1[Kirti S. Bajwa] (12.21.237.241) is first traced even though the IP address of my terminal (12.21.237.98 or 12.21.237.99) is on ARC2 (12.21.237.242)!! Can someone explain why trace is always first going to ARC1 IP? Can someone explain what is going on? Why sometime the dial-in wotks (access the external network) and other times it does not? AT&T is going to call back around 3:00PM (EST) to help. Is 3COM needs some settings changed? Thanks in advance. Kirti

Logging Question
by Brandon Lehmann 31 Oct '05

31 Oct '05

Hello List, We've been having some problems with failed calls to our TC. The calls are failing before PPP can be negotiated. After much testing we seemed to have narrowed it down to one Hiper DSP. What we are wondering is: Is there any way to have the TC log (via syslog, snmp trap, or something similar) all incoming call events and why the call was "cancelled" or hung up? I'm well aware that the TC will report to my radius server a disconnect reason once the call has connected and authenticated; however, the calls are failing before any radius requests can be sent. I would love to have the log contain which slot and channel the call came in on and why the call was terminated (if before successful authentication). Any help would be very appreciated. Thank you in advance, Brandon Lehmann Network Administrator Great Lakes Internet Service, LLC. 218 Justice St. Fremont, OH 43420 blehmann(a)glis.cc 419.334.4551

UP 2.0
by Adam Barnhill 24 Oct '05

24 Oct '05

I realize most of this list has moved on to Wholesale business models but does anyone have any experience with the new UP 2.0 code? Have they improved the V.92/V.44 features? Perhaps they have added partitioning abilities? What are the big changes/fixes in UP2? -- Adam Barnhill Support Engineer, TotallyFabricated.com Information Technology Engineer, Poplar Bluff Internet, Inc. / Semo.net P.O.

We had two of these that wouldn't sell on Ebay for $20 that ended up in the dumpster when we moved.

session id
by Sherwin T 05 Oct '05

05 Oct '05

Hi! I would like to know if the session id/connection id once connected is a unique id meaning the number assigned once connected nevertheless can't get by other user anymore although it was already disconnected. Also, does any one knows how the TC assigned the session id. User Name Conn ID IP Addr Interface 281194 * 65670 * 192.210.10.23 <http://192.210.10.23> slot:1/mod:2 347263 * 393351* 192.210.10.75 <http://192.210.10.75> slot:1/mod:7 Thanks,
