Hostname change more then 8 char

[Enter]

Hi
I am using 11.11, the problem is this, I want to Change host name more then 8 character like 20.when i change the hostname by using set_parms command. the name change successfully and machine reboot successfully. But when i insert uname command the output is only 8 character. But the output of host name show compete name. Is there any method to view compete name in uname commad.
Thanks in advance

Hi Enter
please note that host name has to be 8 characters long, you can setit to more but node name will always be 8 characters, and if node name and host name are different, then some applications will not work,
some applications check the hostname some the nodename, and some need teh 2 to be the same

you will have a conflict and make problems for yourself


at least on 11.11 is what i know...i don't know if they changed in in 11.23 or above

the reason for that is some older apps still use the 8 character hostname/nodename

No.

See the man page for uname(1) and uname(2). The uname command reports the UUCP name, which is limited to 8 characters. The hostname command reports the Internet (or domain/host name) which is limited to MAXHOSTNAMELEN characters as defined in /usr/include/sys/param.h - usually 64. The uname man page also says "It is strongly recommended that sys be identical for all commands and locations".

Hi,

the man page (here it is 11.31) says:

"Setting a nodename of more than 8 bytes is possible only with the appropriate configuration options enabled. It is strongly recommended that all related documentation be completely understood before setting a larger node name. A node name larger than 8 bytes can cause anomalous or incorrect behavior in applications which use the uname command or the uname() system function to access the name."

Sounds to me like "Don't do this!"

On 11.31 there were a bunch of changes made to allow longer names in uname. But if you don't have your applications changed, this may cause problems for them.
