How to configure my EDA tool licenses under Linux O/S ??

Question 1)
How to find the host name of my PC. My login is " root " and I type in " uname -n " command, I got this message: localhost.localdomain. Is this my host name ?

Question 2)
How to modify my bash_profile. Below is my .bash_profile under ./root directory. Any thing wrong with this modification?

# .bash_profile
# Get the aliases and functions
if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin:/usr/local/concept/spicevision-2.1/linux21:$PATH
BASH_ENV=$HOME/.bashrc
USERNAME="root"
LM_LICENSE_FILE=1708@root

export USERNAME BASH_ENV PATH

Question 3)
my license is in the following location:
/usr/local/concept/license.dat

when I execute the following command:
/usr/local/concept/flexlm-8.4/linux21/lmutil lmstat

I got the following error message:
error getting status: Can't find licenses

The first 2 lines of my license are:

server root any 1708
daemon dconcept /usr/local/concept/flexlm-8.4/linux21/dconcept
feature ********
feature ********

Any thing wrong with my setting. My license work in windows 2000.

Question 5)
How to configure my license so that server will start whenever I power up my PC. In window 2000, I know I can select "start service at power up" & "use service" in lmtool. How to do this under Linux O/S ?

Any feedback is welcome

Q1...
A1:
you haven't set this hostname! you can execute ifconfig command to set it or by gui.
this is a good way, in /etc/sysconfig/network, chang the HOSTNAME's value that localhost.localdomain to your-hostname.localdomain.
Q2...
A2:
don't modify the that file that in your home directory, else, only this user can run this program.
in /etc/profile, add this line PATH=$PATHath_program_bin. note, you must place it ahead the export PATH line.
add this line export LM_LICENSE_FILE=port@hostname. this hostname that you set previous step.
Q3...
A3:
change hostname to you set prervious in server line of license file.
change daemon'path to that real path.
in /etc/rc.local, add this line path-lmgrd/lmgrd -c path-license/license.dat -l path-license/license.log.

now, you can run following command sequence to enjoy it:
export PATH=$PATHath_program_bin
export LM_LICENSE_FILE=port@hostname
path-lmgrd/lmgrd -c path-license/license.dat
while you see this license message is correct, you may enjoy it.
