uname and hostname diffrenet, any harm ?

Abdul Majeed Lardhi — Wed, 05 Jan 2005 09:54:38 GMT

Dears,

I have to have more than 8 characters the machine name (hpncbsrvunx1,hpncbsrvunx2,hpncbsrvunx3 etc.)

but the problem that uname -S (system name ) not supoorting this feature !!!

and first 8 char of our host is identical
i.e, hpncbsrv ....
when I do uname -a for all hosts :
HP-UX hpncbsrv ........

but the hosname are diffrent becuase its more than 8 : hpncbsrvunx1, hpncbsrvunx2,hpncbsrvunx3 etc.

Is any harm or problem I will face in future if I implement this approch ???

Regards

While this may well be possible, it is generally not recommended:

The harm you have is deviating from the standard 8 characters for a hostname.

I'm a firm believer in assigning simple, numeric type host names - then use DNS to create aliases for long ones..

IE:

Your hosts:

hp1000
hp1001
hp1002
etc

Then, in DNS, if needed, alias hpncbsrvunx2 to hp1002, etc...

One of these days we may actually remove that pesky 8 character limitation. Not sure if it made it into 11.23 or not.

Anyway, so long as you don't have any software that is mistakenly using uname when it should be using hostname you will probably be OK. Later releases being more likely to be OK than earlier ones.
