Important vShell path

There are a few things you need to know since everything above are quiet abstract.

/etc/httpd/conf.d/vshell.conf  #apache vshell setup
/etc/vshell.conf #vshell configuration

Now make sure that the vshell.conf file has the same as your nagios htpasswd.users or else you might not be able to login to vshell!

Troubleshooting

Once you done above, you might face a few problem like

Unable to login to vshell

Open up /etc/httpd/conf.d/vshell.conf and /etc/httpd/conf.d/nagios.conf
change your vshell.conf AuthUserFile to nagios.conf one
from

AuthUserFile /user/local/nagios/passwd

to

AuthUserFile /etc/nagios/passwd

above might vary but keep that in mind.

Unable to open '/usr/local/nagios/var/objects.cache' file!

Once you login you see the above error and you might want to open up the file /etc/vshell.conf and /etc/nagios/nagios.cfg and change vshell.conf from

; Full filesystem path to the Nagios object cache file
OBJECTSFILE = "/usr/local/nagios/var/objects.cache"

to

; Full filesystem path to the Nagios object cache file
OBJECTSFILE = "/var/log/nagios/objects.cache"

where the correct value should be the same as nagios one
