TurnKey Linux Virtual Appliance Library

Wifi in turnkey linux

Hi,

 

I have  simple question: do turnkey linux servers come with wifi support?

I've installed the file server iso on a laptop (not as a VM) and wired networking works fine. When I want to use the wifi it can't find anything (meaning, in the admin utility the ntworking section finds eth0 and eth1, but neither can find a network or get an ip). I could not find the iwconfig tool either.

So - can I use a wireless network card in a turnkey fresh installation? If so, which tools do I have to set it up (select a network, set encription protocol and password?)

Thanks,

YF

Not supported out of the box, but supported

You'll need to install the following packages to get wireless support. You can configure everything on the cli, including connecting to encrypted networks. I have crib notes lying around somewhere, so if googling doesn't help, let me know and I'll try find them.

apt-get update
apt-get install wireless-tools wpasupplicant

OK, sounds simple,

OK, sounds simple, but...

First I made sure I am connected to the internet (wired) with a simple ping to google.

Then I issued the apt-get update command. I get a [waiting for headers] reply with 0% for a very very long time. I guess apt-get can't find the repositories?

How can I overcome this?

Thanks,

YF

Are you behind a proxy?

If so, you need to tell apt about it. It's quite simple to do, take a look here

Not behind a proxy.

No, I am not behind a proxy.

Here is the full output when I try to do it from the web-admin interface:

I tried pinging the server il.archive.ubuntu.com and could not get to it.

Any ideas?

I just tested it and it seems to load ok here

So my guess would be some sort of networking issue. The fact that you can ping google suggests that you are at least getting some network connectivity. In my experience ISP's default DNS service can be a bit flakey, so the first thing I'd do to eliminate that as a possible issue would be to set your nameserver to 8.8.8.8 (Google's own DNS) which I have never had problems with. The easiest way is to set it in the TKL Conf Console.

Also, even though it shouldn't be an issue, personally I'd do it from the commandline rather than Webmin.

Still no go.

I changed the nameserver and verified it:

root@fileserver ~# cat /etc/resolv.conf  
# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
# DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 8.8.8.8 

 

Then made sure I can ping something else in Israel:

root@fileserver ~# ping www.google.co.il 
PING www.l.google.com (74.125.39.105) 56(84) bytes of data.
64 bytes from fx-in-f105.1e100.net (74.125.39.105): icmp_seq=1 ttl=52 time=93.7 ms

3 packets transmitted, 3 received, 0% packet loss, time 2003ms
rtt min/avg/max/mdev = 87.831/90.160/93.701/2.568 ms

 

Then I tried pinging the repository but it can not be reached:

	root@fileserver ~# ping il.archive.ubuntu.com 
PING foss.isoc.org.il (192.115.211.70) 56(84) bytes of data.
^C
--- foss.isoc.org.il ping statistics ---
876 packets transmitted, 0 received, 100% packet loss, time 881999ms.

 

I can ping archive.ubuntu.com just fine.


When using the webshell I can not run

	apt-get update

either, it is stuck on [waiting for headers].

 

Anything else I can try? Changing the repositories maybe? I am afraid I will use the wrong ones though.

Thanks,

YF

Try using the default ubuntu archive

As Jeremy mentioned, you should update the nameserver in the configuration console, not manually in /etc/resolv.conf as any changes will be overwritten.

confconsole

Anyway, I confirmed that il.archive.ubuntu.com does not reply to pings, so that isn't the problem. I also confirmed that I can use the archive and it is working as expected, so something is strange.

Try using the default ubuntu archive: archive.ubuntu.com, by updating /etc/apt/sources.list.d/sources.list and security.sources.list

I am starting to think it is

I am starting to think it is some local networking problem outside the scope of turnkey linux issues.

I am not using my regualr network here, and looking a bit more into it I found that while my windows machines all connect to the internet just fine, none of my linux machine can access the web, though they can all ping servers.

All of the machines are using manual IP configuraitons, and similar ones, so I am still a bit puzzeled.

I will try it on another network later on and see what I get.

If you have any ideas about this behaviour I would appreciate the help, but it does not seem to be a  turnkey linux issue so I understand if we just close this thread for now.

Thanks for the help,

YF

Hmm strange...

[edit] In light of Alon's comment above, this post is no longer relevant. I'll leave it here anyway.

Just pinged it and not getting any response!?! Perhaps it's a bit flakey? Although that would strike me as strange seeing as it's the official Israel country mirror! Despite this there are other mirrors. The official list of Ubuntu archive mirrors can be found here. Or just use  archive.ubuntu.com (although it may be a little slow - even though the mirror you are using is a sub-domain, it's actually on a local server, or at least should be). For your convienience, here is the only one listed for Israel.

Perhaps check connectivity first though by pinging it. Then alter your sources.list file(s). To be on the safe side create backups of them before you do anything:

cd /etc/apt/sources.list.d
cp sources.list sources.list.backup
cp security.list security.list.backup

then edit the files with nano (nano source.list) replacing the url, save (<Ctrl><x>) then try again.
