Hello,
I have installed Wireshark on CentOS 6.5 from the official CentOS base
repository.
====
Wireshark cannot fully decode NAS field on S1AP protocol.
Error: Unknown-aborting dissection on last NAS fields (these should be
dissected as e.g. EPS Mobility Identity, UE Network Capabilities, ESM
Message Container).
FYI: Windows 7 WS 1.10.7 and OSX 1.6.2 Wireshark latest versions can both
decode the whole S1AP NAS correctly.
Trace attached.
