UNIX for Dummies Questions & Answers

On a Solaris 9 system I had something happen to some of my interfaces; for some reason half of them went down. Since I have over 30 different Virtual IP's (or logical IP's) up on ce10 I don't want to take the time to find out which ones are up and which ones are down or even run the addif command 30+ different times to up the interface.

I just want to down them all, then up them all while on the console.

Anyone know of a command to accomplish this all in one easy step or a start-up script I could run?

for instance my /etc/hostname.ce10 has over 30 entries that look like this
addif <hostname> netmask + broadcast + up

wc -l /etc/hostname.ce10
35

Code:

$ ifconfig -a | egrep "ce[0-9]*" | awk '{ print $[/B]<#> }'

where <#> represents the column number (in order from left-to-right starting at 1) containing the unique interface id, it's prolly $1 for first column, if memory serves me proper!

if the above command statement works (or whatever you get to work), then store it to a variable and run a for-loop on it

e.g. if the above worked perfectly...

Code:

$ TEMPLIST=`ifconfig -a | egrep "ce[0-9]*" | awk '{ print $

Code:

<#>[B] }'`

#note that the commandstatement is enclosed in back-quotes (key next to number-1 and usually on same key with ~

Then run whatever set of commands you want done for each interface

Code:

$ for i in $TEMPLIST
do
command1 $i
done

where $i will represent the interface name in each iteration of the for-loop; you can substitute i with any expression, but when writing the command statement to be performed for each interface (after the do statement), represent interface name with whatever subsitute for i you use, precede with $ (like any normal variable)

for-loop uses i as a variable to represent each entry in the $TEMPLIST

hope that makes sense
should work like a charm

anyone had any luck in running the /etc/init.d/network command on Solaris 9?
