We are trying to acquire some numbers that are in XO's Inventory but none of
the aggregators we work with resell XO Services. Thought I would ask here.
This would be a one-time deal I suspect so you'd probably make a quick fee off
me for your efforts.
The issue is lame ? the provider we worked with who sold us these numbers went
bankrupt without telling us, and now the numbers (which were active) went back
into inventory. We need to grab them back before they disappear.
Please email me off-list.
Thanks,
Darren

Sorry I have not seen something similar. I personally was able to use the
below steps and get a working pcap for wirewhark. Can you see SIP messaging
when you run a normal debug on the Adtran in the CLI?
*Thanks?*

Blast from the past!
I have tried to follow something very similar to this (didn?t use an
access-list) on some Adtrans I have in the field. Some are 908Es, some
Netvantas 6300. When I do this, I can certainly see tons of data, can
convert it with text2pcap but not much I could identify as SIP when I know
there is SIP running through the box. Am using the Adtrans SIP proxy ? not
sure if this has anything to do with it?
Anyone seen anything similar?

Hi Zak,
The following is the whole procedure on how to obtain and convert a packet
capture to a pcap file.
>From the command line, we have the ability to look at every packet coming
in and out of the router, along with the ability to limit that debug with
an access-list. This is best done from a telnet or SSH session, as the
console can drop some of the output due to a limited buffer size.
It is preferable to not have any other messages pop up that may interfere
with the capture text. The events and any other debugs should be turned off
before performing this debug. This can be done with the following commands:
Router# no events
Router# undebug all
The general command is:
<> = optional
Router# debug ip packet <access-list name> <detail / dump>
NOTE: It is not recommended to run this command without referencing an
access-list.
---------------------------------------------------
To limit the traffic to and from a particular peer:
ip access-list extended test
permit ip any host <IP in question>
permit ip host <IP in question> any
For example:
ip access-list extended test
permit udp host 192.168.40.22 any eq 5060
debug ip packet test detail
debug ip packet test dump
---------------------------------------------------
If you desire to see more than what 'detail' provides, choosing 'dump' will
output the entire packet in text form. This can be copied to a text
document and converted to an actual packet capture.
The program Wireshark (www.wireshark.org) comes with a utility known as
Text2Pcap. Copy (text2pcap.exe) from the Wireshark folder to a root drive,
as well as the text file. Run the following command from a DOS prompt:
text2pcap.exe -e 0x800 <Text Filename> <Capture Filename to Create
(extension .pcap)>
The capture file can then be opened in Wireshark. If the unit is running a
firewall, you will probably see every packet twice (once entering the
firewall & once leaving, depending on the ACL you are using); the second
may be after a NAT process if NAT is enabled.
If the traffic is across a VPN, the second packet will not be seen since it
enters/leaves the router encapsulated in VPN.

Does anyone know the TCP Dump commands for the Adtran TA908e CLI?
*Thanks-*
