failConfigFileError

Forums: 

Hi,

Does anybody have any idea how to fix: failConfigFileError? I am using Debian Linux with TOD, TFTP and DHCP. I have the option 122 settings in there and the file is OK. I'm using gupimacmta. I just can't seem to get rid of that error. In Progress Telephony-TFTP stuck there. It's only 9 MTAs on our network. The macs are in the DHCP server and everything. This error comes and goes periodically and I'd love to know how I fix it without trying 4,000,000 things.

thanks

Thomson TH520 not sending MAC Addr to Prov Server - Need MIB!

Forums: 

Hi All,

This is my first question on this board so please allow for mistakes:)

I am provisioning MTA's using Incognito Provisioning Server and in the MPS log I get an error when MTA sends provisioning request
The error: Ignoring Provisioning Enrollment Inform: incorrect length of MAC Address (0)
I believe that the MTA is NOT sending MAC Addr and therefore the ProvServer nacks the request. Does anyone out there know the SNMP MIB for sending MAC Addr?
Something like this: 1.3.6.1.4.1.7432.1.1.3.3.0

docsis_server 3.5 segfault

Forums: 

Im running docsis_server 3.5 on debian 5 (lenny) and have run into an issue.
The server normally runs fine and is provisioning about 50 modems. But when the cmts is reset and all the modems try to get an IP at once the dhcp daemon crashes. This is all I got from gdb the last time it happened:

Program received signal SIGSEGV, Segmentation fault.
[Switching to Thread 0xb7b9b6b0 (LWP 18113)]
Parse_Modem_Caps (message=0xbfebe001) at dhcpd-options.c:240

Trace provisionning

Forums: 

Hello,

Is there a way to trace all the provisionning sequence (dhcp,tftp, mta, etc..) from the CMTS ? or a tool to follow the differnt request from the cmts to the others device of the network and from the others device to the cmts (modem, mta, cpe ...).
How to do ?
And is there a document to be sure that anything is missing when a cmts configuration is finished ?

Thank you for your help !

Web Interface for docsis-server?

Forums: 

Have seen a few references to home grown php frontends for docsis-server here in the forum,
but no actual links to any resources for same. Anyone have anything worthwhile developed that
they would be willing to share? Webmin and phpMyAdmin just seem very klunky for simple tasks
like adding or modifying modems, etc. Many thanks in advance for any assistance.

Kind regards,

UBR10012 12.2SBC and EPC2203 SIP client - dynamic SF problem

Hi,

it seems I cannot make my eMTA to work. On cmts, I cannot create dynamic service flows, so the call is just dropped.

Can anyone help me, please!
