Hi,
is there any reliable way to determine if a script is run in the toolserver cluster, i. e. can make use of the database servers & Co., without checking for hostname being wolfs- bane, nightshade or names-to-come?
TIA, Tim

Check if it can connect to the database server?

No, as:
a) the database servers may be down, and b) running the script on another box somewhere on the net would require waiting for the timeout/rejection of the connection *on* *every* *run* :-).

Given that you need to give it server-specific database login details anyway, you can presumably just check to see if those are available.

Hostnames will change over time. Domainname (toolserver.org) should stay the same.

I use this in my shell scripties:
if [ "`hostname --domain 2>/dev/null`" = "toolserver.org" ]; then echo on cluster else echo off cluster fi

there is no --fqdn option either. hostname on Solaris does not accept any options.

I ended up using this in my .bash_aliases:
if ([ `uname` = 'Linux' ] && (hostname --fqdn | grep toolserver &>/dev/null)) \ || ([ `uname` = 'SunOS' ] && (check-hostname | grep toolserver &>/dev/null))
Clearly, users of non-bash shells should use >/dev/null 2>&1 instead of &>/dev/null. It's probably cleaner to do `which check-hostname
/dev/null` instead of the explicit OS check. So you could do
if ! `which check-hostname >/dev/null`; then alias check-hostname='hostname --fqdn' fi
Then use check-hostname as you like. Of course, from the man page, it looks like check-hostname is part of sendmail, so I don't know how reliably available it is, but it's worked for me so far. :P

In PHP:
$DEBUG=(preg_match("/\btoolserver.org$/", $_SERVER['SERVER_NAME']) ? false : true); if($DEBUG) // Not on TS. else // ON TS
