Change of Subject line, things were getting confused....

It was worth a try, still didnt work though *sigh*
Just in case I'm missing something.
ls -la /usr/local/nagios/var/rw

chmod'ing with Terry Inzauro's suggestion - see below, default group perms
are rw-)

(lots, but all the same)
I'm not wrong in thinking that the httpd is running under the APACHE user,
am I?
Thanks

I think the nagios user,the apache user need to have write access rwx access
to that file. make sure that each of the respective users have the
necessary perms. or just add the nagios user to the group owner in the
/etc/group file.
worth a try?

I'm afraid its a case of been there, done that...
but just in case I did something wrong, I tried again...
Stopped Nagios and $INSTALLPATH/var/rw/nagios.cmd disappeared (as it should
- see I even tried reading the manual :-D )
Used the /etc/rc.d/init/nagios script to start it,
$INSTALLPATH/var/rw/nagios.cmd re-appears with the default permissions
prw-rw---- 1 nagios nagiocmd 0 Dec 6 17:20 nagios.cmd
CHMOD'd 777 it, still receiving the same error when attempting the command.
Have even tried restarting the httpd :( which runs under the 'apache' user,
which is part of the nagiocmd group.
Incidently the parent (rw) directory has the permissions,
drwxrwS--- 2 nagios nagiocmd 4096 Dec 6 17:20 rw
Maybe someone will spot where im going wrong.
Anyway, have a good weekend all.

I cam across the same error once. If there was a nagios process running,
kill it. If there is a $INSTALLPATH/var/rw/nagios.cmd file, delete it.
Next, start nagios with the /etc/rc.d/init/nagios script. Then try the
request again. If does the same thing. try chmodddddding the
$INSTALLPATH/var/rw/nagios.cmd file for something like 777, then work it
backwards from there.

FYI,
I have just built up a clean install of Redhat 8, and Nagios1.0
I have got Authentication setup and working ok (I can view cgi's), however I
am unable to send commands from the Web Pages to Nagios (Scheduling Checks
etc.)
I am recieving the error
Error: Could not stat() command file
'/usr/local/nagios/var/rw/nagios.cmd'!
The external command file may be missing, Nagios may not be running,
and/or Nagios may not be checking external commands.
An error occurred while attempting to commit your command for processing.
:(
If possible I would suggest you backup the config CGI's (hosts services etc)
and start over, it seems to be easier than troubleshooting.
Chris... yup another Chris.
Just for reference I've included the bits below so you can cross reference
your config files.

Another interesting tibit, I tired disabling use_authentication and
setting up a default user, but I still get the same issues.
Thanks

My httpasswd.users file and everything is setup totally correctly and
use_authentication=1 is set. I have also tried setting all the
authorized_for's = * but to no avail. From the sounds of it, it looks
like this might be an issue with RH8.0 or Apache 2.0.40 that ships
default with RH8.0. Is there anyone on this list that has Nagios
working on RH8.0?
Thanks,
Chris
