Hey there all.
I was wondering if there is anyway to set TCP/IP settings in Bash, such as IP, Subnet Mask, and DNS server.
Thanks in advanced

[Also: is there anyway to scan for wifi networks and connect to one via Bash?]

It depends on what OS you use. In GNU/Linux, *BSD etc. you may change network settings with ifconfig (see man 8 ifconfig). route will help to setup routing table (gateway). DNS servers are typically listed in /etc/resolv.conf file.

However, you should refer to the documentation of your OS/distribution. It may happen to offer some distribution-specific tools to configure network (e.g. in Debian there is /etc/network/interfaces file to define all the networking settings in one place).

If your OS not windows you can do almost anything on the command line that can be done in a GUI, and often much more. You need to learn how to use the relevant commands manually first so then you can convert into a script.

Oh and on modern Linux systems you should use the "ip" command rather than "ifconfig", which is slowly being phased out

Well, I agree with you. But ifconfig is pretty much everywhere, and iproute2 (ip) only on modern Linux (ipfw in FreeBSD?).

P.S.


I tried this google search: is there any way to scan for wifi networks from command line in linux?

And found this list of: Wireless LAN Sniffer Applications and Scanners for Linux

hey jetxee... we really don't approve of the "RTFM" mentality. If you don't know an answer right off the top of your head, feel free not to comment (as it's not really helpful). If you know of a website that can help directly, feel free to post that instead. But posting a link to a google search? I think we can do better than that.

cynic - I happened to write a program that does much of what you are looking for I think. It's posted on our "Mother Site" at this location. If you have any questions about it, let me know.

Welcome to Bashscripts.org btw!

OK, I got it. But the answer was given the line below. Personally, I would prefer to have a link to the regularly updated list of similar tools rather than just one random name which came to mind.

I shall edit the previous post to make it clear that the first links points to google. The second one points to the answer.

Thanks for the replies guys. I'm trying to make a script to connect to a certain wifi network, but one that needs full TCP/IP settings.



Heh, I've been lurking this site for a while and am loving it. Thanks for the warm reception
