Question

.

• TWiki version: Dec 2001 version
• Web server: apache 1.3.12 (Unix)
• Server OS: Solaris 8
• Web browser: IE 5.1
• Client OS:

I have configured TWiki, I can run commands such as edit, preview but not view. running http://myserver:port#/cgibin/view tries to find http://myserver:port#/cgibin/view/Main/WebHome and it returns Internal Server Error.

The error log has these messages:

[Fri Apr  5 16:05:29 2002] [error] [client xxx.xxx.xxx.xx] File does not exist:/usr/local/apache/htdocs/pub/wikiHome.gif
[Fri Apr  5 16:05:31 2002] [error] (8)Exec format error: exec of /usr/local/apache/cgi-bin/view failed
[Fri Apr  5 16:05:31 2002] [error] [client ....] Premature end of script headers: /usr/local/apache/cgi-bin/view
[Fri Apr  5 16:05:39 2002] [error] (8)Exec format error: exec of /usr/local/apache/cgi-bin/view failed
[Fri Apr  5 16:05:39 2002] [error] [client ....] Premature end of script headers: /usr/local/apache/cgi-bin/view

The gif file does exist in the correct location. Have set the permission to 666.

TWIki.cfg is something like this (This is not the complete file just posting the initial setup)

#                   /cgi-bin/view/Main/WebHome : link of TWiki icon in upper left corner :
$wikiHomeUrl      = "http://twiki.org/";
#                   Host of TWiki URL :    (Example "http://myhost.com:123")
#$defaultUrlHost   = "http://your.domain.com";
$defaultUrlHost="http://snow:8080";
#                   /cgi-bin : cgi-bin path of TWiki URL:
#$scriptUrlPath    = "/twiki/bin";
$scriptUrlPath = "/cgi-bin";
#                   /p/pub : Public data path of TWiki URL (root of attach
ments) :
#$pubUrlPath       = "/snow/pub";
$pubUrlPath        ="/pub";
#                   Public data directory, must match $pubUrlPath :
$pubDir =           "/usr/local/apache/htdocs/pub";
#                   Template directory :
#$templateDir      = "/home/httpd/twiki/templates";
$templateDir =      "/export/home/twiki/templates";
#                   Data (topic files) root directory :
#$dataDir          = "/home/httpd/twiki/data";
$dataDir =         "/export/home/twiki/data";

testenv results into no error messages.

Answer

Are you sure that your shebang line is correct in the view script? Apache seems to be saying that it can't exec the view script at all, so it may also be an Apache misconfiguration - see this email.

Try running ./view >/tmp/foo.html from the TWiki bin directory - if this works, it's probably Apache.

Also, download the latest testenv from CVSget:bin/testenv, and try the PATH_INFO test to see if that's something to do with this (unlikely, but it may help).

You should also check that the pub dir and the GIF are readable by 'nobody' (in fact, the directory also needs to be writeable for attachments to work.)

Thanks for the help. I was able to move further in this. The #!/usr/bin/perl line had to do with the problem. I had changed the path in all of these. Somehow the files got corrupt or what I am not sure, I copied new set "view" file to twiki/bin and it worked.

But not the problem is I cannot save any thing. I can create/preview, but when I try to save I get the following error message: Topic save error During save of file Main an error was found by the version control system. Please notify your TWiki administrator. /usr/local/bin/ci -q -l -m'none' -t-none -w'guest' /export/home/twiki/data/Main/WebHome.txt 2>&1 1>/dev/null ci: /export/home/twiki/data/Main/RCS/WebHome.txt,v: Permission denied

Go back in your browser and save your changes locally.

Topic WebHome . { OK? }

RCS works fine on my system, the permissions are correct (666) but there is no directory called RCS unser Main. Even if I remove RCS from the URL the error does not go away.

Problem is solved!

Sounds like there is still a problem - check that you have this setting in TWiki.cfg, which stops the use of the RCS subdirectory:

$useRcsDir        = "0";

Also, see TWikiDebugging and update Store.pm as mentioned there so that you can trace the exact RCS commands executed.
