TheLQ's questions

I am attempting to install boinc-client on a few Ubuntu Server machines. However there's one problem: With both depending on the same libraries (just different architectures), one requires X while the other one doesn't?

Both servers a fairly vanilla with not much installed besides the base image. Both are running Ubuntu Server 11.10. Command run was sudo apt-get install boinc-client

32 bit machine

The following NEW packages will be installed:
  boinc-client libcurl3

64 bit machine

The following NEW packages will be installed:
  boinc-client fontconfig:i386 ia32-libs ia32-libs-multiarch:i386 lib32asound2 lib32bz2-1.0 lib32ffi6 lib32gcc1 lib32ncurses5

Why is there such a difference between the 64 bit and 32 bit versions? Both use the same libraries, so adding other nonsense doesn't make sense

Ever since Ubuntu 8.10 when I first started I couldn't get my old Linksys WUSB54G wireless card to work. At least in 11.04 it somewhat works only when you set a static IP, and even then speeds are pitiful (The ping time to my router is 10ms(!), DNS takes a while, and bittorrent is painful). Yesterday I bought a Linksys WUSB100 only to have the same problems.

With these two devices not working, do Linksys wireless cards or the Ralink modules that power them in general work well in Ubuntu? Or is this pretty much the standard experience?

Note: I know I can use ndiswrapper but at least with the WUSB54G its very flaky and causes lots of kernel panics in both Ubuntu and Fedora. Its also a workaround that I'd prefer not to rely on

Note 2: I'm asking this since I'm returning the WUSB100 I just bought and needing to know if I can use Linksys products in Linux

I am looking for a multi-threaded file copy program. The reason I'm interested in mult-threading is that I have 240 GB of files (most being pretty small) I need to transfer.

In Windows land there is Robocopy, Richcopy, Teracopy, etc. In Linux I can't seem to find any tool that can do this.

Is there any tool you all are aware of that does multi-threaded file copying?

After a two year hiatus to Linux, I try it again out again. And then I run into to driver issues...

I have an old Linksys WUSB54G v4 Wireless USB Adapter. In previous versions I had to use a combination of Ndiswrapper and Wicd to hope of getting it working. In 10.10, apparently there are built in drivers for it.

Unfortunately they don't work. Fails to connect to my WPA network, fails to connect to my open unencrypted network. Wicd fails at "Obtaining IP address" or when using static IPs fails at verifying connectivity to network.

Getting fed up I tried the ndiswrapper approach. Installed and configured, but still not working, even when blacklisting the rt2570 module. So for some debugging I added some lines to my /etc/modprobe.d/blacklist.conf file

blacklist rt2570
blacklist prism54usb
blacklist rt2x00lib
blacklist rt2x00usb

Restart and find this:

lordquackstar@quackbeast:/etc/modprobe.d$ lsmod | grep rt2
rt2500usb              18049  0 
rt2x00usb               9779  1 rt2500usb
rt2x00lib              27275  2 rt2500usb,rt2x00usb
led_class               2633  1 rt2x00lib
mac80211              231541  2 rt2x00usb,rt2x00lib
cfg80211              144470  2 rt2x00lib,mac80211

Seems to be ignored... Tried this:

lordquackstar@quackbeast:/etc/modprobe.d$ sudo rmmod -f rt2x00usb
ERROR: Removing 'rt2x00usb': Resource temporarily unavailable
lordquackstar@quackbeast:/etc/modprobe.d$ sudo rmmod -f rt2x00lib
ERROR: Removing 'rt2x00lib': Resource temporarily unavailable

and couldn't connect. Restarted and was back to the same modules loading.

Maybe there's something in the log:

lordquackstar@quackbeast:/etc/modprobe.d$ tail -n100000 /var/log/syslog | grep rt2

Seems to be autoloading. So this means that even if I pull it out, remove the module, and get it working, it still won't work when its plugged in all the time.

Any suggestions on how to either fix the rt2x00usb driver or permanently block it from loading? Note that I already have ndiswrapper installed

Byobu looks very broken in PuTTY. I've already fixed the key mapping issue, but this issue isn't specified in the man page or even Google:

Notice the misplaced position of the list of windows, the broken selector position, the duplication of the last window, the random a in the top right, and the misplaced apply option. You can't see this, but the last option is not selectable.

Is there some option in PuTTY I need to use in order to see this correctly?
