Problem with Ad-hoc wireless network Windows to Linux (no ping)

Hello All,

Sorry for the verbosity of this post...

I am trying to set up an ad-hoc wireless network between two
computers; one runing Windows XP and the other Linux (2.6.x,
Slackware).
After I have set them up I cannot ping the Linux machine from the
Windows machine.

This is what I have done so far:

* Made sure that the Wlan card is running on the Linux machine
(it is; it's a RT61 based D-Link DWL-G510). It works fine when in
"managed" mode (connecting to an access-point); I'm using the latest
firmware/drivers I could find.
* Made sure that the Wlan card is running on the Windows machine
(it is; Intel something-something built into a Dell laptop).

Then I try to set things up.

** On the Linux machine:

$ modprobe rt61  (load module, card is recognized)
$ iwconfig ra0 essid box   (ra0 is my RT61, set SSID)
$ iwconfig ra0 channel 11  (we are in Europe)
$ iwconfig mode Ad-Hoc     (this is what I want; no encryption)
$ ifconfig eth0 down       (just in case; remember ra0 is the WLan
card)
$ ifconfig ra0 10.0.0.1 netmask 255.255.255.0 up  (interface comes up)

$ ifconfig ra0
ra0       Link encap:Ethernet  HWaddr 00:19:5B:70:2D:D2

0 lo

From what I can see the "ra0" interface is up and running and it's
wating for an "Ad-hoc Handshake" or similar. We also have a
rudimentary routing table.

** Now I configure the Windows machine

* Enable Wireless (OK)
* In the network list I can see the "box" station configured on the
Linux machine.
* Tell the Wireless card to start an ad-hoc network with SSID "box"
on channel 11 with no encryption (it's "open")
* Set properties for the "wireless network connection" in the control
panel so it reads:

   IP-address ........ 10.0.0.2
   Netmask    ........ 255.255.255.0
   Standard gateway .. 10.0.0.1

After a few seconds I get a "green light" and Windows tells me I am
connected to the "box" network. Now the Windows machine has IP
10.0.0.2 with netmask 255.255.255.0 (ipconfig.exe confirms this).

Now: I still cannot ping the Linux machine (10.0.0.1 [255.255.255.0]).

I get no reports of connection problems. Still every ping times out.
Of course, when connected to an "ordinary" lan I can ping the Linux
machine from Windows without problems.

I suspect that I am doing something stupid with the routing
thingamajig
but I can't figure out what.

Any ideas? Has anyone else managed to set up a simple ad-hoc
connection in this fashion? What am I doing wrong here?

Regards,

Tobias Andersson

It looks like you didn't setup the routing on the linux box.

# route add default ra0
or
# route add default gw 10.0.0.2

There should be two ra0 entries.  The second should be similar with the
Destination / Gateway entries swapped.

# route -n
# netstat -r

Beyond that it looks like you're setup/connected.  Just that any pings
don't have a route to travel to return to the windows box.  A ping from
the linux box to the windows box will likely give a no route to host
error.  Or destination host unreachable.  Assuming the firewall isn't
dropping them altogether.

Thank you for your suggestion:

I did add a default gateway but the problem persists.
The machine simply won't talk to each other over the ad-hoc link.

This is not limited to simply pingning the machines. I started proftpd
on the linux box and
tried to connect to it from windows:

> ftp 10.0.0.1

but it won't (no response from server).

> Beyond that it looks like you're setup/connected. [...]

I know. Windows says the machines are connected (point-to-point) and
it's interface has
good values; still no packets from the Winbox arrives at the Linux
box.

Is there some special "thing" you have to do in Linux when setting up
an ad-hoc link in this fassion?

I haven't followed this thread,
but it might be worth setting one end - preferably the laptop -
to Managed, and the other to Ad-Hoc.

Thanks:

but it did not help. Besides, the only way I could connect in this way
(managed to ad-hoc)
is by setting the ad-hoc card in "master" mode (so the card basically
pretends to be an
access-point device); but the linux software doest not support this.

I should mention that the network settings as such are sane. When I
"wire" the machines
to a small switch they behave perfectly (same settings as in original
post but substitute
ra0 for eth0).

The problem persists. Both machines say that the ad-hoc link is up but
no machine will talk to the other.

I wouldn't say special thing.  But obviously something you're missing. 
Make sure the windows box is setup for TCP/IP and not just NetBeui(sp?). 
And too little information has been provided.

Need outputs for linux from:

ifconfig -a

iwconfig

route -n

netstat -r

And depending on disto, contents of /etc/network/interfaces or other file.

For windows output for:

ipconfig /ALL

route PRINT

Something is missing in there.  Or it might just be the firewall dropping
everything.  I'm not sure why your wireless is ra0 though.  Normally
that'd be wlan0, or eth# if your distro didn't account for wireless.  I had
to change the udev rules to get mine to be wlan0.  It was just too much
headache to try and remember which was wireless and which was ethernet,
eth0 or eth1.

I guess one should ask, not that you have the resources to check (multiple
machines multiple OS's).  Can the windows box connect to other windows
box's?  Can the linux box connect with other linux box's?

As far as AdHoc or Managed.  Doesn't really matter.  AdHoc is generally
for smaller networks and computer to computer connections.  But it
can/will handle multiple connections.  Managed just has a lot less
overhead on larger networks.  In general if the connection is AdHoc, then
both machines should be set to that.

As far as default gateway.  Try the default interface first.  There can be
only one.  One default that is.  And unless the other box is setup with
NAT or ICS (windows), then it's not likely a gateway anyway.  Not to
mention that 10.0.0.2 might not be it's address.  With only 256x256x256x256
addresses to choose from.  Technically 254 since 0 and 255 are special.

Does iwconfig say that ra0 has wireless extensions?  If not, then you
probably need a wireless device driver.  atmel, prism54, ndiswrapper,
wlan-ng, ???

The winbox is set up to use TCP/IP.

The RT61 driver assigns ra0 as the wireless device. The name should
not make a difference. I have connected to an access point earlier
with this device (in managed mode) without problems.

I haven't tried this yet. I will.

It does. See output of iwconfig above.

Thanks.

I don't really understand your response.
Why can you not set your laptop card to Managed? eg with
        sudo iwconfig ra0 mode Managed
Are there WiFi cards that don't support this mode?

I don't have great confidence that this will work -
but I don't see why it is not possible.

I used to run WiFi this way - 
with a PCI WiFi card on my desktop in Ad-Hoc mode.
I found I had to set my laptop Orinoco PCMCIA card to Managed
for the connection to work.

However, I have used a LinkSys WR54GL access point for some years,
so the issue no longer arises for me.

Other suggestions: is there a firewall running on your Linux box?
Or on the Windows box?
Are you running NetworkManager?
What are the relevant entries in /var/log/messages on your laptop?

There are drivers and driver version(s) that only let you change a value
once.  My broadcom cards used to have to have the essid set first,
otherwise you couldn't change it.  Using the ndiswrapper driver of course.
But that was a long time ago.  Things are better now, but I wouldn't say
perfect.  I still have to set mode/rate/key off/essid with iwconfig before
running dhclient3 to connect to some wifi hotspots(McDonalds / Texas Rest
Stops). Especially those still on 802.11b.  Sometimes I even have to set an
IP for myself before it'll let me connect using dhclient3(Texas Library).

Perhaps I should clarify. The wlan card on the Linuxbox can be set to
managed
mode yes but then the windows laptop refuse to make an ad-hoc
connection
to it. I must set both cards to "ad-hoc mode".

The problem persists. I'm thinking of getting a couple of cheap USB
bluetooth
adapters and setting up a network that way instead.

I don't follow you.
I thought you didn't have a connection any time.

I doubt if that is wise.
I haven't read of many people setting up a Bluetooth LAN
and being happy with it.

I'm pretty sure your problem is solvable,
if you go through the possibilities.

Also, the fault may lie with the Windows machine.

1) Is there a Windows firewall running?

2? What relevant messages do you get in /var/log/messages
on your Linux machine?

3) Is NetworkManager running?
If it is, try turning it off.
If it isn't, try turning it on.

4) What does "iwlist ra0 scan" say?

iwlist ra0 scanning

And various other wireless-tools options to ID what the linux box does
see.  I still think it's a routing issue.  Windows or linux.  A netmask of
255.255.255.255 means it can only talk to itself.  A netmask of
255.255.255.0 means it can talk to any box with the first three numbers
matching.  As long as that box is listening.

when you ping, what are you getting?  no route to host?  host unreachable?
 or just 100% packet loss?

linux ad-hoc and managed mode wireless networking
I was wondering how to setup a wireless card under linux to be able to connect ad-hoc as well as managed mode to a wireless network. I have a mobile computer and a mobile printer that can communicate in ad-hoc mode when they are together in the field. When I bring the mobile computer back to my stationary managed mode wireless network I want to be able to connect and download info that was gathered in the field from the mobile. How do I connect from the ad-hoc mode wireless mobile card to the managed mode stationary card? Do I have to disable and re-enable the mobile card every time?

Strange problem: no problem with Linux, when I boot windows 2K network is down...
Guys: This is very strange problem, looklike this problem is not going to leave me for months. I have a computer with Windows2K and Linux. I have Netgear 4-port Switch/Router (connected to DSL modem). If I boot with Linux, everything is OK, I can be on-line, also two of my other computers works fine. If I boot my PC with Win2K, then immediately all computers are down. None of the computer connected to network. I thought some problem with LAN card, so I went for early bird sale on day after Thanksgiving and I got one LinkSys PCI LAN card and one Router and I plugged new LAN card into my machine, then I booted with Windows, same problem. No problem on Linux side, then I changed my Router with new Router, samething. CAN SOME EXPERT SUGGEST ME, WHAT IS HAPPENING with my Win2K machine. But if I bypass Router and connect directly from DSL modem to my Win2K PC, then it is working. Why win2K pc is not working with Router. I have two more XP machines connected top 4-port switch (one is with cable and other one is with 802.11), they are working fine. Can somebody suggest me, how can I fix this.

If you're using a fixed IP address insread of DHCP, you have to tell it everything it would normally get from the DHCP server, including the IP address of your favorite DNS server (which your router gets from your ISP).

adding a linux box to a windows network
Im trying (legitimately) to add a gentoo linux server box to the windows NW at work. IT are happy for me to do it as long as it doesnt involve them in any more work .(they re overworked++++ Im sympathetic). I wall connection to the NW & 2 boxes on my desk Ive got this far currently linux box uses ntlmaps to authenticate at the MS poxy server and I can connect to the gentoo servers (for installs etc ) via the local proxy ie local request->127.0.0.1:5865 -> eth0->MSproxy->www linux box gives out IP address on eth1 to windows box and I can ping back and forth and ssh to it. next step is to get the windows box to connect to the rest of the world via the linux server and MS proxy. I was initially going to use shorewall (what im familiar with) to forward incoming eth1 TCP traffic to eth0 , but im not sure about how I negotiate the MS proxy. Do i have to go winbox->eth1 on server -> NTLM proxy(127.0.0.1:5865)->eth1 ->MSproxy->www is this easier with squid? anyone know how to configure squid? its easy to configure squid. 1st thing to decide whether you want a "transparent" proxy or an "authentication" enabled one ? in both the cases you can use squid. The configuration file squid.conf is well document. you will need a squid user and another squid group. squid -z to create the cache directories. "server squid start" to start the squid. By default it will run on port 3128. If you want it to be a transparent ...

Adding wireless ibook to linux network and printing
Hi, I am about to buy an ibook (first mac) and am wondering about using it with my existing linux computers and a HP 2410 printer/scanner/fax. The 2410 is attached (usb) to a computer running linux and set up in cups. It is not a "network/ethernet" printer. If I get a wireless router and network the computers I guess if I have cups broadcast from the linux box than the ibook should be able to be configured to see and use the printer. Is that correct? More impotently, If I install the mac software that HP provides, will I be able to use it in the ibook even though it is not ...

Hi, afaik cards with Prism chipset are recommendable (haven't tried one my self - kinda expensive and hard to get in my region). Look at http://prism54.org/ for more information. Another chipset I can recommend is Ralink RT2500, although the drivers (http://sourceforge.net/projects/rt2400/) are still kind of buggy in a few issues. What I can't recommend is Realtek R8180 chipset - the drivers work only on Kernels 2.4.20 and 2.4.21 and there are a few opensource attempts to produce better drivers, but i haven't found one for myself that worked properly.

Wireless networking under Linux
I have a small LAN that I would like to transform into a wireless one. The problem is, I still don't have a clear idea on how to do it. For instance, is it possible to plug some gadget into the usual NICs of my PCs, or do I need to buy specific, wireless NICs for each PC? Do I need to buy any specific hub, or just about any wireless hub will do? Are such devices (i.e. wireless NICs and hubs well supported under 2.4 kernels? Does one need drivers not already included with the kernel? Finally, how much can this exercise cost per PC? Any help will be much appreciated.

You don't tell us if you currently have a hub or switch. Let's assume you do. You need an access point that connects via an ethernet cable to your hub/switch. No drivers needed.

Ideally, what I'd like to do is the following: 1) Plug a WL-330 into the standard NIC in my PC. 2) Plug another WL-330 into one of the ports of my hub. With this, would my PC communicate wireless with my hub? That is; would, for all practical purposes, this allow me to successfully connect my PC to my hub wirelessly.

Problems with wireless card AirLink101-AWLC3026 on Linux (it shuts down sporadically and can't connect to protected networks)
I switched my friend's laptop from Windows into Linux (Gentoo). Kernel is 2.6.19-gentoo-rc5. Wireless card worked on Windows with no problems. But on Linux there are two problems: 1. Card connects ok to unprotected network (no password) but shuts down periodically (after ~15 mins) for no apparent reason. Power light stays up but signal light doesn't flash at all. Once it is shut down 'ifconfig' still shows it as 'UP' but no packets go through. 2. It somehow doesn't connect to encrypted wireless network. Key on Windows was 10 zeros (0000000000). But when I set this through iwconfig: iwconfig wlan0 essid <myessid> iwconfig wlan0 key s:0000000000 ifconfig wlan0 up dhcpcd wlan0 I tried to drop "s:' but still the same problem. Power light on the card begins flashing which means that it can't connect. My card is AirLink101 and I use binary blob driver with NDISwrapper. I solved the problem myself. When the problem was happening I used 2.6.19 kernel with ndiswrapper-1.51. 2.6.19 was released in the early 2007. And ndiswrapper-1.51 -- just recently in December 2007. Problem is gone once I upgraded the kernel to 2.6.23. ...
