#13 No Frame.html generated

[Leandro Dardini]

I run the latest svn on a simple pcap and get the following warning. Tshark version is 1.8.10

TShark 1.8.10 (SVN Rev Unknown from unknown)

No /tmp/call/frames/Frame.html was generated

# callflow /tmp/call.pcap

Run it once more as a regular user, not as root.
What's the result.

tshark: -o flag "gui.column.format: "No.", "%m", "Time", %t, "Protocol", "%p", "srcport", %S, "dstport", %D, "Info", "%i"" specifies unknown preference

Edit bin/callflow and change gui.column.format to column.format, I have the same issue.

Code updated to prevent to run as user root: https://sourceforge.net/p/callflow/code/227/

' # callflow 4126839.pcap
callflow: error: do not run as user 'root'

Update to svn version 227.

Hi Robert,

I believe the issue being reported by Leandro is the message from tshark, not the warning about running as root.

tshark: -o flag "gui.column.format: ..." specifies unknown preference

Older versions of tshark do not have the gui.column.format preference. I experienced the same issue on CentOS 6.5 with TShark 1.8.10.

More recent versions of tshark warn:

Preference "column.format" has been converted to "gui.column.format"

I haven't determined at which version number this behavior changes. It would be nice if callflow could check "tshark -v" and use the version appropriate option, or just use column.format and ignore the warning.

Replacing gui.column.format with column.format resolved the issue. This was going to be part of the patch in bug #11 but I didn't have a newer version of tshark to see if the older preference was forward compatible. Looks like it is.

If you're reading this on the mailing list please ignore the last diff. I
forgot that I had backed out the 'gui.column.format' change before posting
it.
