Welcome to LQ.

Best with ns2 : Depends what you want to do.
Different versions / different patching behaves different.

Some versions works perfectly on CentOS 6, Fedora, Slackware, etc.

Some old versions prefer old Ubuntu / Debian versions for best test results.

Post # 9 :

You should probably type ns instead of n5 !

Or use one of the examples found in ns-2.xx/tcl/ex/ ; I.e. $ grep -n color *.tcl
Example : web-traffic.tcl , lines 28..44 ( ns-2.34/tcl/ex/web-traffic.tcl )

Code:

# set up colors for nam 
for {set i 1} {$i <= 30} {incr i} {
    set color [expr $i % 6]
    if {$color == 0} {
	$ns color $i blue
    } elseif {$color == 1} {
	$ns color $i red
    } elseif {$color == 2} {
	$ns color $i green
    } elseif {$color == 3} {
	$ns color $i yellow
    } elseif {$color == 4} {
	$ns color $i brown
    } elseif {$color == 5} {
	$ns color $i black
    }
}
