UNIX for Dummies Questions & Answers

I want to change the IPsetting and the broadcast setting.
With ipconfig I get this:
hme0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
inet xx.17x.18x.xx netmask fffffff0 broadcast xx.17x.18x.xx
ether yy:0:yy:b6:yy:xx

What command(squence) do I use to change the inet and broadcast? Or where do I find that sequence?

Does changing this automatcally change the telnet IP as well?

Yes, it does.

The command you need is ifconfig. Depending on the OS you are using, there may a startup script or file that will set this information for you. You need to find that script and make your changes there.

Based on the interface (hme0) I am assuming Solaris.

To do this command line:
# ifconfig hme0 xx.17x.18x.xx netmask 255.255.255.0 broadcast xxx.xxx.xxx.xxx up

Under Solaris I am not sure where you set the broadcast (and no longer have a Solaris box at home to check). I *think* it is simply the highest IP is the subnet as defined by the netmask. If the netmask is wrong, it can be changed in /ete/netmasks

The sledge hammer way to do this is with sysunconfig
BE warned that this puts the system back to "as new" with regards to network info, root password, etc., and will reboot the box. If the box is using NIS, NIS+, LDAP, and assuming you are not familiar with configuring these, I would suggest not using sysunconfig.

OK thanks.

It's Solaris 8.

Where do I find the mentioned script?

I'll have a look in the Solaris guide monday to see whether I cann get everything straight.

well, it's not done by a script in solaris... just edit your /etc/hostname.hme0, and make sure there is the right entry in your /etc/hosts
# cat /etc/hostname.hme0
server
# grep server /etc/hosts
10.0.x.x server server.unix.com

gP

Thanks.

I'll have a look first.
