Ubuntu Networking :: Verifying (and Installing) Mac80211 In 8.04?
Mar 1, 2010
I am reasonably technical but new to Linux. I almost guarantee there will be simple things that I don't understand. I am trying to get a USB wireless adaptor working with aircrack-ng and have managed to find that I should have the mac80211 drivers installed and active to support the rtl8187L and B chips. (I also need to patch them apparently, but first things first).
I am working with Ubuntu 8.04LT (I am fairly sure) and do not seem at the moment to be able to update to a more recent version on the target machine. The kernel is 2.6.24-27. I followed instructions to blacklist the r8187 and ieee80211 modules, which seemed to go quite smoothly.
I now need to get the mac80211 module loaded, but can't find out how. The information at Aircrack-ng and related sites seems to indicate that I expect the drivers to be already in my build of Ubuntu but they do not seem to be loading. The suggestion seems to be that they will load automatically. I have found some stuff in /lib/modules/2.6.22-14 and /lib/modules/2.6.22-27, and also in /usr/src/linux-headers-2.6.24-27 which is probably relevant but I don't know what if anything to do with it. If anyone needs more detailed information, just tell me what you need to know, and how to get it.

I tried installing the mac80211 framework on ubuntu 10.10 but after i install it and restart my system , none of my network connections work.
i found a solution to that problem which is a very weird solution. because none of the network connections are working . i try to activate the wireless driver from the System->Administration->Additional Drivers. But it fails , but after it fails my wired network connection comes back online. and then i have acccess to the internet . After that i activate the wireless driver again and it works.
This is obviously the worst possible solution ever. So what i don't understand is why the mac80211 framework is causing these problems. after applying my "solution" i thought of checking the modules installed on my system using lsmod and i see mac80211 there. i don't understand why it is still there after i executed the "sudo make uninstall" command . code...

I need with some iptables rules. I've done all I can, Googling all over, to cover as many exploits as possible and the following script is what I've come up with. The current set up works and I've checked with NMAP. I just need some sort of confirmation that this is pretty much what I can do.
Code:
LAN="eth0 eth1"
RANGE=10.1.0.0/17
WAN=eth2
# Delete all existing rules
[code]....
Also, if I wanted a broadcast to be relayed to all subnets within a defined range, how would such a iptables rule look like? I need this in order to find a networked Canon MP640 printer.

I need to update my mac80211, but I don't know how can I do that. In the update manager there's is no update for it, but I know that there is a newest version. At least, at development branch.

I have set up an ubuntu server running PPTP Server for VPN connections. I can successfully connect from a laptop within the LAN, but taking that same machine to an internet connection and trying to connect back in does not work. The only difference is that when I connect from within the network, I am obviously using the server's LAN (non-routable) address, and when I am connecting from outside the network (from Verizon Business DSL ), I am using the Comcast connection's static IP address.
I have a static IP address on a Comcast Business Class internet connection. Router is set to forward pptp and GRE ports.
Works:
VPN Server <- Laptop
iPhone -> Internet -> Router -> VPN Server
Does not work:
Laptop -> Internet -> Router -> VPN Server
Here is the weird thing. I have an iPhone that connects flawlessly every time through it's AT&T data connection. The laptop however, gets to "verifying username and password", and then returns error 619. It seems that there is an issue only when going through the router using the PPTP client built into MS windows.

I just started dual booting Ubuntu 10.10 on my mini 10v with OS X a couple days ago, so I'm still pretty new to Linux.
But anyhow, I was attempting to change my User ID number so I could access the files in my User folder on my OS X partition. So, I tried entering the following commands:
sudo usermod -u 501 yourusername
sudo chown -R 501 /home/yourusername
Of course, smart me should've realized I should've been logged out and on a different administrative account to do this. But I didn't, and I believe the second command didn't work. So, whatever, I thought I'd try logging out and logging in as root.
So, I logged out, tried logging in as root, and of course, no dice because I didn't know the password. So then I tried logging onto my account and upon logging in, I got two errors. One was about ".ICEauthority" and I didn't keep track of what the other one was.
Great. So I did a quick google for the error, then tried entering these codes:
$ sudo chown user:user home/user/.ICEauthority
$ sudo chmod 664 /home/user/.ICEautority
$ exit
[Code].....
And again, I think the last one didn't work. So, I looked up how to login as root, changed the password and logged in as root successfully. Then, whilst in root, I entered:
/usr/sbin/usermod -u 12345 joeuser
/usr/bin/find / -user 701 -print | xargs -t chown joeuser
/usr/bin/find / -user 701 -exec chown joeuser {} ;
Upon entering those, I logged out and logged back into my account and everything was a complete success. No error messages anywheres AND I could access the files in my Mac user folder.
So, here's my question. How can I make sure I have all the right permissions I need? Or do I already have the all of the permissions I had before changing my user id?
Did those last three lines of code I entered "override" all of the codes I had entered previously? I just want to make sure verify I have all the correct permissions necessary so I don't run into any issues later on.

Is there a way in svn to verify if an already existing file tree that "should"be at a given revision is in fact correct at that revision?I had an earlier revision and obtains patches via svn diff for subsequent revisions, and applied them up to a given revision (or head). Now consider that perhaps some error happened during the application of these patches, or perhaps a file just got corrupted. What I would want to do is just verify if the tree I have now at this revision is the exactly tree I would get at this revision ... without actually pulling down the whole revision.Note, I want to do this for exports, not for checkouts. That may make it simpler since the result of svn diff seems to only be for the actual data files.

I've been having trouble writing to DVDs on one computer, and I am trying to figure out whetgher the problem is hardware or software related, or, perhaps, both. The brasero CD/DVD writer puts the md5 checksums of each of the original files in a hidden file on the DVD. I think it then calculates the sums of the copies and compares, but the last time I did it, it told me it had permission problems with the drive, and that failed. When I put the DVD in, udev finds it and mounts it in /media with me as its owner. Apparently, brasero mounted it some other way, and presumably that caused the problem.
Secondly, after I brought it up again, I went into the /media mount point and did md5sum on the files there. One of them a gzipped tar file, produced and input/output error. Yet if I use cmp to compare that file with the original it finds no difficulty. So what is going on? Finally, I have tried to write shell scripts which use cmp to compare the original files with the copies. The general form is
cd XXXX
find $* >> /tmp/X
for i in `cat /tmp/X`
do
cmp $i YYYY/$i
done
where XXX is the mount point in /media and YYY is the original directory containing the relevant files. This works fine except that if the file names have spaces in them, the shell script treats each word as a new file name. So I need some way to arrange things so that `cat /tmp/X` returns the complete file name. Nothing I've tried works.

Is there a command that can be run to verify that a users cron job has run successfully?
Platform is Ubuntu 8.04 LTS.
I have scripts in /home/useraccount/bin/
running
crontab -l
While logged in as user results in:
# m h dom mon dow command
@hourly /home/useraccount/bin/script_1
@hourly /home/locateruser/bin/script_2
I realize scripts could send email or write to a log with a timestamp, but wondering if there is just a way to verify it ran from the command line.
I ran
ps -ef|grep cron
... and it shows
root 4358 1 0 Mar12 ? 00:00:00 /usr/sbin/cron
Not sure if this indicates it is running the jobs though....

I was dual-booting Windows 7 and Ubuntu 10.10 till recently. Then I had to reinstall Windows. After re-installation of Windows I did not try to restore Grub and deleted Ubuntu partitions on disk thinking that I'll install newer Natty version. But now when I try to install Ubuntu 11.04 using pen drive it gets stuck in bios showing message "Verifying DMI pool data ....". I also tried to boot GParted, memtest and Windows 7 with the same pen drive. Same thing occurred with GParted and memtest but Windows 7 installation did not stuck and went as usual. So I guess it's not hardware.

I'm trying to create a torrent file via the command line. I used "transmisson-create", but since the .torrent file is binary I can't read it using "less" or "nano". Is there a way of verifying that the torrent I created was correctly done? I know I could probably upload the .torrent file to my public server and then use another torrent client to test, but I simply want to see what's inside the .torrent file to verify that it got all the files I wanted. I cd'd into the directory with the files that I want to torrent and ran the following command.
Code:
$ transmission-create -p -t http://tracker.openbittorrent.com/announce *

opensuse v11.3
linux 2.6.34.8-0.2-desktop x86_64
It took me 3 tries to get is ISO image that matched the md5 checksum on the download site. At 8 - 10 hours each it was a PITA. The first simply aborted 1/3 of the way through (HTTP direct link). The second used wget, got a full file but the checksums didi not match. The magic method was Bitorrent.
All this has left me with an uneasy feeling about the contents of the DVD created from the ISO. Is there a way to test the DVD contents?

I've been trying to burn Suse 11.2 to a DVD now for a couple of days but I keep running into trouble. When verifying a disk after burning Suse on it it keeps giving me errors. I've tried Nero and ImgBurn, different burners, different ISOs, different burning speeds (downloaded via torrent and http) but it keeps giving me the verification error.
The only thing I haven't tried is a different brand of DVDs but until now I've never had any problems with this brand.

I am trying to install Ubuntu 10.10 on a Dell Latitude 1001 laptop which has XP installed. I have selected the option for Ubuntu to run alongside Windows but, on selecting the Ubuntu option at boot up, the installation stalls at "Verifying the Installation Configuration". Before this window came up, a very brief text message flashed on the screen - something like "getpwuid failed" (it was on the screen for only a second or less, so I didn't have chance to note it down. Does anyone have any suggestions as to what may be wrong (I have never used Ubuntu so please make any suggestions very simple).

I had Fedora11 (default layout) running on a separate hard drive (winXP on the other drive). After the FC drive failure I replaced the drive and did a fresh install again. This time I tried a custom layout to keep the /home on a separate partition. The installation went without a hitch, but on first boot the system hangs with "Verifying DMI Pool Data......"
XP boots fine though. Looks like grub doesn't get loaded. I can boot with the installation cd and get into recovery mode, everything seems fine on the fedora disk. Fdisk result:

What I did to configure the network:
1) remove network manager
2) make ip address entries in /etc/network/interfaces and /etc/resolve.conf files.
when I do networking restart it is showing
"reconfiguring network" [OK].
However Google.com is an unknown host. I am getting the feeling I am missing something. The network adapter is showing green led . Does it have something to do with the microsoft networking that's running in my office?

Today I put in two brand new RAM sticks, same brand as the two I already have in there only difference is the new ones don't have the giant heatsinks that cover the stick. I have 4 slots for RAM, and I had 2 gigs in there, 1 gig in the first, and 1 in the 3rd. I put the two new ones in the empty slots. Everything worked fine, so it seemed. I was able to boot up, log into Ubuntu. It looked like everything worked, said I had internet access by the icon up on the top panel. The only thing that was curious was my weather app wasn't updating. So I went into a web browser, and the home page showed up fine. Which was the default, the ubuntu google search engine. I tried to go to another site though, and it kept looking for the site, for a while but never found it. I tried multiple sites, same thing. I tried to ping www.ubuntu.com, and www.yahoo.com and it just hung for a while, after a while it couldn't find it. I tried ifconfig eth0, and even just ifconfig. It showed that eth0 was connected, it had the ip address, the DNS address, the MAC, everythting. Only problem I could see was at the end it said something like Interupts: 18, I don't know if that's normal or not.
So I tried then to reset the router, no difference. I tried resetting the hub (at least I think it's a hub, could be a switch or something), which is connected to the router, and the hub connects to my computer. Now that, made it worse. Now the icon for my internet has disappeared, well it tried to reconnect but can't. ifconfig eth0 brings up no ip address anymore, no DNS, no nothing. I tried rebooting, didn't help.
So here I am, and I'm definatly in need of some help. I find it very hard to believe that adding new RAM would kill my ability to get online, that doesn't make any sense to me. I am using Ubuntu 9.10 64 bit, had 2 gigs in there, and now have 4. Edit: I tried rebooting once again, and this time when logging on Ubuntu it for some reason checked my filesystem for errors, found none as far as I can tell, then logged on. Once I logged in, it connected again to the internet, but it's doing the same thing it was before I restarted the hub. Says I'm connected, but can't visit any webpage, weather isn't updating, but homepage is showing up, etc.[URL].. Which is the same RAM I had in there, minus the one in there had a giant grey incasing/heatsink on them.

Just installed 10.04 but can't seem to get wireless working. Fry's brand USB device (FR-54USB). Device works when booted to Windows but light never comes on in Ubuntu so I'm guessing it's a driver issue.
It looks like this is a D-Link chipset but I can't tell which one. lsusb shows the following:

Everything was working fine today and for many days before today. (this is a pretty fresh install of 10.10 Maverick).
I installed a VPN connection (PPTP) to connect to work.
That worked fine. i connected, remoted into the machine I wanted and did what I had to do.
I was ABOUT to disconnect from the VPN and when I clicked on the network manager icon BAM it said DISCONNECTED. saved me another click or 2. But now I have no networking at all.
The network manager icon says "Networking disabled"
I tried: warm booting a couple times cold booting a couple times
I also tried:
Code:
service restart networking
and
Code:
sudo /etc/init.d/networking restart
[Code].....
I would really just like to delete/uninstall anything that has to do with VPN's and see if that works. Or maybe reinstall network manager. Are those reasonable places to start?
