Dear All,
I have recently been building a dissector for an 3GPP ASN.1 based
protocol which uses a tcp based transport.
I have followed the developer's guide (9.4) relating to the re-assembly
of fragments, and this seems to work fine.
However, after a tcp segment loss ( I have the preference analyse tcp
sequence no. switched on), the ASN.1 BER PDUs are no longer detected
and decoded as expected. Somehow, synchronisation is lost. I presume
this is due to the sequence of segments on the wire.
I am new to building wireshark dissectors and with the ASN.1 tools. I
presume there is some additional logic required in my dissector - would
be very grateful if someone could point me in the right direction?
Best regards,
Chris
