hi!

i´ve just finished the installation of litespeed and i have some problems:
when i want to start the helloworld script on the demopage, nothing happens. the same thing in the admin-space: when i click on a "edit"-link, a new window pops up, but there is no content.

these messages are from the server-log:
2004-02-18 21:56:29.376
INFO
Start FCGI [phpFcgi]: failed to bind to uds://tmp/lshttpd/php.sock, fast cgi might be running,
2004-02-18 22:03:06.384
INFO
Start FCGI [fcgiAdminPHP]: failed to bind to UDS://tmp/lshttpd/admin_php.sock, fast cgi might be running,

this is one of the many errors in /opt/lsws/logs/stderr.log after browsing the admin-space:

PHP Warning: Unknown(): open(/tmp/sess_a38ee2b0cfe006ff4d3da9ef2ad02ea3, O_RDWR) failed: Permission denied (13) in Unknown on line 0
PHP Warning: Unknown(): Failed to write session data (files). Please verify that the current setting of session.save_path is correct (/tmp) in Unknown on line 0
PHP Warning: session_start(): open(/tmp/sess_a38ee2b0cfe006ff4d3da9ef2ad02ea3, O_RDWR) failed: Permission denied (13) in /opt/lsws/admin/html/admin/authHeader.php on line 6

the tmp directory is mounted with the following parameters:
/dev/sda7 on /tmp type ext3 (rw,nodev,noatime)

it looks like a problem with the rights and i dont know anyway how to solve it...
can you tell me what lib´s and programs should be installed before using litespeed? i run lsws on a gentoo-linux machine and there is nothing preinstalled.


thx for helping!

Thank you for trying our product.
looks like your /dev/sda7 is full, make sure there are enough free space left. Make sure the user who the web server running as can write to /tmp/.

thx! parts of the problem are now solved; after chmod -R 0777 /tmp , the admin-space works!

I could not think of any thing that could cause helloworld script stop working.
Please turn on the debug log by changing "Debug level" to "high", and check lsws/logs/error.log or just use the log viewer, see if you can figure some thing out.
Please send the debug log to bug@litespeedtech.com if necessory.

Thanks.

this line was added in stderr.log after the click:
/opt/lsws/DEFAULT/cgi-bin/helloworld: line 5: cannot create temp file for here document: Permission denied


where does the script want to create a temp file?

Looks like some thing wrong with the CGI written in shell scipt.
Please try the CGI script on command line as "root" user and the user who the web server process is running as.

Code: 
cd lsws/DEFAULT/cgi-bin/
./helloworld
sudo -u <username> ./helloworld
I think the last command will fail and produce the same output as the line in stderr.log, you need to figure out why the shell script does not work, maybe it is just a permission issue.

when i start the helloworld with user root in a shell, then it works.
when i start with sudo -u webserver ./helloworld in a shell, the error appears.

after that i set the writing permissions for tmp:
chmod 0777 /tmp
now sudo -u webserver ./helloworld worked fine in the shell, but not in the browser.
what else should i change?

The previous result might be cached by the browser, just restart the web server, do a no-cache refresh from your browser (press "shift" or "ctrl" key) when you click the refresh button.
Should work now.

something changed! the "permission denied" error disappeared, but a new error was created.
this is from /opt/lsws/logs/stderr.log:
/var/web/DEFAULT/cgi-bin/helloworld: fork: Resource temporarily unavailable


but with sudo, the script was correctly executed ?!

Are you running other daemon server like Apache with user name webserver? You need to increase the resouce limit for CGI from web admin interface, under server's "security" tab, set "Process Soft/Hard Limit" to higher than the total number of processes running as "webserver".
