Hi,

The maximum number of characters for the hostname is system dependent. HP-UX on the S800 has a limit of 8 characters. This is defined in the C language as 9 characters - 8 ASCII characters followed by an ASCII zero (null). If a remote system tries to call a S800 machine and has a hostname of more than 8 characters, it will fail to communicate with that system - reporting that the system is unknown.

Suggest you keep the hostname to 8 characters or less.

Hope this helps.

Hi,

In HPUX 11.00,

If we make the system hostname to be more than 8 characters it will accept that but after when we reboot at the startup screens it will display "setting hostname [FAIL]" and the Xwindows will not work.We can't login into CDE.

But in the file "/usr/include/sys/param.h" value for the parameter "MAXHOSTNAMELEN" is by default set to 64.

Better to use 8 character name if required you can use alias with more characters.
