how to install fonts on RHEL4?
 

I have this error why trying to run an application from HPUX(via ssh).

To install fonts in RHEL4, simply copy the font file(s) to the appropriate folders in /usr/share/fonts and then re-boot.
There are some commands to be run after installing fonts, but they seem to get run when you re-boot.

I don't know, however, how this relates to the problem described.

you mean my problem is not related to font?

From you post, I am not sure what your problem is--I GUESSED that you might need to install a font.
