I have a tcpdump file created with:
tcpdump -s1500 -iem0 -w wnssl.dump port 443
Once I let it capture some packets and terminate it, the file is not really readable. I use the following to display the capture:
ssldump -nr wnssl.dump
It reads a couple packets (properly) and then prints
ERROR: Length mismatch
tcpdump -nr wnssl.dump displays all the packets.
The tcpdump file is attached.
