I'm also using the supergoogle script and I'm having the same prob. It appears that google have banned the "Tcl http client package"
I logged all packets sent and recieved when searching google through the bot and I did the same with my windows machine...
When you connect to a website your browser gives the server a client agent id the one used with the super google script is: "Tcl http client package..." and the one used in IE 6 and other versions is: "Mozilla/4.0 (compatible; MS IE 6.0; Windows 98)"
once google is told that the browser your using is "Tcl http client package..." it tells you to read the terms and conditions etc and refuses to do your search.
The agent ID is stored within the tcl libs so I guess unless we can change the id within those files and re-compile them we're stuffed
uhm im in no way a l337 hax0r or anything i just tried this to see if it worked out:
i edited the http.tcl file in /usr/local/lib/tcl83 and search for 'agent' in the top of the file. i replaced the 'tcl http package.....somehting" with jamman's suggestion:
'"Mozilla/4.0 (compatible; MS IE 6.0; Windows 98)"' and now it works for me. dunno if it will work for others without destroying something in their setups, as i know very little about everything etc. etc.
Indeed google.com changed something to there webserver so it will only reply to 'real' browsers that give legit useragent replies.
I have posted a 1.2fix version on this site but way too many bugs were present in that version, so i have asked slennox to take it down for now... you can apply the above hack to the supergoogle.tcl ofcourse to make a temporary fix, for now.
I have allready begun work on a 1.3 version and will continue this over the weekend, when i am happy with the result and it is tested on some different configurations i shall post it, should be done by beginning next week.
The 1.3 version will feature google groups search (as suggested by BarkerJr) and some bugfixes (such as the # sign-bug in a request). As I had little time last few months i could not look into it sooner; well i have some spare time at hand now so i should be able to deliver it on time.
Anyway, i am happy there are so many users allready; just a post to let you know i am not gonna let you people down.
