Help on these two needed ...!!

Folks

I need help on following two.

Say i am getting two values like this

::1:953 and :::8005

I need to replace "::" (first two colons with a * ).I can get these values in a variable.How to tweak this variable to separate out the way i want? Anything after third ":" should be set to new variable.Anything before third ":" should be checked for "::" and if yes,replaced (or echoed by *).

abhi@myhost:/home/abhi> /bin/netstat -anee --tcp -udp |egrep -v "Active|Proto"
(No info could be read for "-p": geteuid()=24616 but you should be root.)

.

I am unable to get rid of line starting with "(No.....".
How do i remove this line from comamnd's output?

some thing like this :

/bin/netstat -anee --tcp -udp |egrep -v "Active|Proto|^  \(No"

or

/bin/netstat -anee --tcp -udp |egrep -v "Active|Proto" | sed -n '2,$p'

or

/bin/netstat -anee --tcp -udp |egrep -v "Active|Proto" |  awk '$0 ~ ! /No/ {print }'

yeah...it worked coz 'f1' is a file....

i can't use file here... i need o/p directly and once from the command line....

As i can't use the command , i saved the output in a file and tested.

The same will work fine from command line also once you piped your output to this.

i had hoped so...but it isn't....
