Wireshark · Ethereal-users: Re: [Ethereal-users] Calculate Time Difference for each SYN-SYN/ACK pairs

[Lim Boon Ping <syseeker@xxxxxxxxx>]

Hi Luis,

 

Thanks for you reply. :).

 

This link http://www.ethereal.com/distribution/buildbot-builds/ethereal-setup-0.10.9-SVN-13430.exe  at http://wiki.ethereal.com/Mate_2fGettingStarted seems to be broken, I couldnt manage to download.

 

Due to the above obstacle, I downloaded Windows version of ethereal-setup-0.10.10.exe.  Unfortunately, ethereal quit immediately i hit 'Apply' after setting configuration filename at Preferences->mate. And subsequently I am never able to open ethereal. I tried to reinstall ethereal,  and the same error occurs.

 

Next, I tried to run from command prompt by entering

 

tethereal -o 'mate.config_filename:tcp.mate' -r mylogfile.pcap -z proto,colinfo,'mate.tcp_ses.Duration',mate.tcp.synack

 

However, it returns ---> tethereal: -o flag "'mate.config_filename:e:\tcp.mate'" specifies unknown preferences.

 

Refer to the ethereal's preferences log file, i found the below:

 

# The name of the file containing the mate module's configuration
# A string.
mate.config: e:\tcp.mate

 

Well, changing from  mate.config_filename to mate.config still yield the same error. And ethereal works properly after commenting this line. :|

 

I am rather interested to try out this experimental version, looking forward your reply. :)

 

Regards,

Jocelyn
