The prompt format is controlled by the environment variable PS1. What is its value? Here's mine on CentOS box, having a prompt similar to what you require:

Code:

[root@linux ~]# echo $PS1
[\u@\h \W]\$

Everything's probably depending on how PS1 is generated by your profile/boot scripts with respect to bash. Also, sometimes like in Gentoo and Slackware, a normal user has a different prompt compared to a root user. If you can, you may check and read /etc/profile and ~/.bashrc.
This is very dependent on your distro's implementation though. Sometimes more scripts are related to the variable like /etc/env.d/*.

If you're using a Red Hat like distro (RHEL, CentOS, Fedora etc) you would need your hostname configured in /etc/hosts and /etc/sysconfig/network:

Code:

# more /etc/hosts
127.0.0.1       myhostname localhost.localdomain   localhost

# more /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=myhostname
