sngrep EEP send and listen not working #396

Closed sathiyaraman closed 2 years ago

sathiyaraman commented 2 years ago

Hi Kaiyan,

I have tried a scenario, where, Server A(A.A.A.A) act as an HOMER with "sngrep -L udp:A.A.A.A:9060" and, Client B(B.B.B.B) act as a capture with "sngrep -H udp:A.A.A.A:9060". Expecting the SIP packets which B captures should send to A and visible in the A's sngrep window, but Its not visible in A's sngrep. Kindly confirm whether I'm using the syntax correctly.

Thanks & Regards, Sathiya

sngrep - 1.4.7 in both A and B

Kaian commented 2 years ago

Hi!

The syntax is correct and this is how I usually test HEP listener, so the problem may be related with configuration.

Please provide the output of sngrep -D for both Server and Client.

Regards!

I will also recommend you to try the latest master version if you plan to also save the captured packets to pcap. That's a feature that have been recently added and may also contains fixes for the problem described in the issue.

Hi Kaian,

I have copied the config dump of both Server and client.

HEP_Server.txt HEP_Client.txt

Kaian,

I'm more interested in the Hep capturing feature. but, I have customized the sngrep to capture diameter packets too, had more changes in 1.4.10. instead of porting all changes to sngrep's 1.5.0 can I merge the updates in those 4 files listed for "hep: support saving HEP packets to PCAP #270" (with the commit id :3a63a0836c42231a52e595ecd678f946e13f82a1) such that i can save the captured packets to pcap right

From the config, it looks like the client is sending in HEPv2

SettingId: 43    SettingName: eep.send.version     Value: 2
SettingId: 44    SettingName: eep.send.address     Value: 192.168.151.134
SettingId: 45    SettingName: eep.send.port        Value: 9060
SettingId: 46    SettingName: eep.send.pass        Value: foo
SettingId: 47    SettingName: eep.send.id          Value: 2002

And the server is expecting HEPv3

SettingId: 48    SettingName: eep.listen           Value: on
SettingId: 49    SettingName: eep.listen.version   Value: 3
SettingId: 50    SettingName: eep.listen.address   Value: 192.168.151.144
SettingId: 51    SettingName: eep.listen.port      Value: 9060
SettingId: 52    SettingName: eep.listen.pass      Value: foo
SettingId: 53    SettingName: eep.listen.uuid      Value: off

That commit contains the required code to allow saving received packets from HEP using UI dialog (F2). But there are some limitations, because saving data while capturing from multiples sources is not supported.

Other commits in current master address those problems: they add support for just capturing HEP in listen mode without capturing from network interface. Changes are not too big, so consider also picking these ones:

after aligned the version as same in server and client, now HEP working as expected. Thanks for the great support Kaian.

Thanks for the additional commit references for the enhanced capture. have gone through those changes and looks good to integrate. will start working on those to integrate and test. will get back to you if found any blocks EOD.

Awesome, I will close this then, as the related problem has been solved.

Feel free to reopen if you need some light about the changes in the mentioned commits.
