Thanks for the follow-up. Found the tutorial you mentioned and tried exactly that. It seems that as soon as is set the text for the column, I cannot change it any more. I tried a number of permutations and still the result is I can set it COL_INFO only once.
This a plugin dissector and everything else seems to work just fine. I would like to add some more info to the COL_INFO for various message types that I dissect. Any idea what changes were made to the plugin API?

If it's a plugin, it seems you're not the only one experiencing this problem, although I highly doubt that it's a Wireshark bug. There have been some changes to the plugin API somewhat recently and I think your problem may be related to that. You might try first to re-read the most recent README.plugins and possibly even reviewing the following tutorial: http://www.codeproject.com/KB/IP/custom_dissector.aspx. In addition, it's probably a good idea to compare your plugin files with the Wireshark built-in plugin files. - Chris -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Jason Dick Sent: Sunday, March 02, 2008 3:01 PM To: [email protected] Subject: [Wireshark-dev] 0.99.8 col_append_str fails I am writing a dissector for a custom protocol and found that I am unable to add additional information to the INFO column. See the following code: if (check_col(pinfo->cinfo, COL_INFO)) { col_append_str(pinfo->cinfo, COL_INFO, " more info"); } It appears that after the initial setting of the column, pinfo->cinfo is no longer writable. That is col_get_writable(pinfo->cinfo) always returns false. It still returns false even after I run: col_set_writable(pinfo->cinfo, 1); Has anyone else run across this? I thought I had this working for another dissector on 0.99.6 but I don't have that code with me right now.
