This article applies to:

KnowledgeBox version: 1.5
Browser versions: all

The usual symptoms for this problem are getting a "Page cannot be displayed" error in the internet browser when trying to access the KnowledgeBox. And if you receive and "Connection refused" error when attempting to telnet into the KnowledgeBox (Refer to the following article for an explanation of telnet My_KnowledgeBox_is_not_working_what_do_I_do )

Rebooting the KnowledgeBox is also the first option to try. This will attempt to restart the KnowledgeBox's apache web server software. Try to telnet once again onto the KnowledgeBox. If it still fails then we will have to look on the KnowledgeBox itself i.e. log on to a terminal. Please refer to either How_do_I_connect_into_my_Knowledgebox_remotely_via_Putty or How_can_I_get_a_shell_on_an_Appliansys_Cachebox for an explanantion on logging on to your KnowledgeBox.

The command to try will be the following:

ps -auxwww | grep ^kb | grep httpd

You should receive an output to the screen that looks something like the following (a number of 'httpd' processes all started by the user 'kb'):

If there are no httpd processes, then it is possible KnowledgeBox itself is not running or the apache software is not running.

If you try the following command to see if there are any processes started by kb

ps -auxwww | grep ^kb

If you do not receive anything i.e. you just recieve the prompt again, then the KnowledgeBox has probably not started, this could be because the rc.knowledgebox is pointed to in the linux startup scripts. Other wise if you do receive something

 

 

Well what I'm trying to get to is, when attempting to start apache manually, if you get an error stating "non-numeric argument in /home/knowledgebox/apache/2.0.47/logs/httpd.pid" then just remove the file and restart the KnowledgeBox. On restarting the file will be recreated.
