Ubuntu :: File Commander With Queue Function?
Nov 25, 2010Im running Ubuntu/Gnome and have been using Wine to run Total Commander, an App that a truly love but has its limitations under Wine. So Im looking for a native replacement for it, but it has to have the queue function of Total Commander. I have tried Tux commander and Gnome Commander and neigther of them seam to have it?
Krusader supposedly has it but needs about 300MB of KDE librarys and such. Are there any other alternatives?
OpenSUSE Hardware :: Printer Seizes To Function Since 11.4 - "There Is No Print Queue"
Mar 27, 2011Since I changed my System from openSUSE 11.3 x86_64 to openSUSE 11.4 x86_64 my printer (Samsung ML-2850 via USB) seizes to function (clean installation). The printer connects to two machines via a KVM-switch. On the other machine (Windows 7 x64/Windows XP x64) the printer is working fine. This did not change when I switched the Cables/KVM-ports. In addition, when I was using openSUSE 11.3 x86_64 the printer also worked fine. All necessary CUPS-packages are installed:

Programming :: Get Length Of Run Queue And Swap Queue?
Nov 3, 2010is it possible to get the length or even the items of both queues, the run queue and the swap queue? I've googled a lot but had no luck. Maybe I havn't used the correct search words...
Is there any header and/or code example to use structures or any API to get these information from the kernel or the scheduler?

Feb 12, 2010I am a windows programmer. There I wrote a firewall and VPN System. It was easy. Simply, I USED WINPKFilter by ntkernel.com.What I need is to GET, Edit, and Send the raw Layer 2 packet before reaching to IP Stack.My friends were saying that linux is Ideal for Networking purposes. But for now I say that Linux is very bad in this field and I should say that windows is much better (I beg your pardon)After tens of hours for searching I got nothing good. The hook system of IPtables is not GOOD for me because it has not Ethernet header and also the packets are defragmented when I caught them.
I tried ebtables but it has no user space queue like IPTABLES. What I exactly need is to be able to reach to the chain of raw Ethernet packets and be able to modify them and resend or inject some ethernet packet packet. I Dont Want to go inside the KERNEL. (As windows I want a userspcae library). Dear linux expert I beg your help. Do not let me turn back to windows.
Networking :: Using SFQ Queue To Divide Bandwidth Per Connection / Computer
Feb 4, 2010Can the SFQ queue be used to divide bandwidth not only per connections but also per computer? E.g. if two computers download something each computer gets half of the bandwidth. I'm trying to do my own script based on wondershaper and would want to divide the bandwidth between all devices so that one device can't saturate the uplink.

Networking :: See The Number Of Packets Dropped By Kernel Due To Insufficient Queue Size?
Sep 15, 2010As is known, there is a queue lies between the kernel subsystem and the network driver for incoming data. And if data come when this queue has no space for it, the data got dropped by kernel. Is there some way to see how many packets are dropped due to this buff penury? I tried netstat -s but could not find something useful. On the other hand, I found this 12176 packets collapsed in receive queue due to low socket buffer from netstat -s. I think this is something related to the per-socket buffer, but not the incoming queue between the network driver and kernel. Is this right?

Programming :: Passing Data From Interrupt Handler Function To Tasklet Function?
May 18, 2010I am doing some Linux kernel programming for my research project. I need to record the timestamp (by using cpuid and rdtsc) when an interrupt handler (top half) is first invoked. Due to the time critical nature of the problem itself, I have to do the timestamping inside the interrupt handler itself (the first operation when the handler is called). However, I understand that tasks that are not so time critical should be deferred to a tasklet function (bottom half) for processing because other interrupts are disabled in a (top-half) interrupt handler. I am currently out of idea on how I can pass the timestamp information that I have obtained in the interrupt handler to the corresponding tasklet function.

General :: Write Script To Use Function And Still Keep Function Active?
Feb 21, 2010the function terminates if no key is pressed for 10 consecutive seconds. I tried using the -t option as suggested in some forums, but my version of showkey doesn't have the option of changing the timeout. The options I get are:
-h --helpdisplay this help text
-a --asciidisplay the decimal/octal/hex values of the keys
-s --scancodesdisplay only the raw scan-codes
-k --keycodesdisplay only the interpreted keycodes (default).
Is it possible to write a script to use this function and still keep the function active until an interrupt is recieved?

View 4 Replies View RelatedUbuntu Networking :: The Enable Wireless Function Is Grayed Out?
Dec 1, 2010I'm using Ubuntu desktop 10.10 on an Hp Pavilion dv2700 laptop. Most of the time I have had no issues, however on two separate occasions the wifi and bluetooth have been disabled, the switch on the front of the computer has no effect.the enable wireless function is grayed out, so I was not able to enable it. The first time it happened, (I didn't have an Ethernet cord at the time), I booted into windows Vista, thinking I could connect to the internet and find an answer. Low and behold I had the same problem in windows, however I was able to enable the wifi and blue tooth in windows. Now, rebooting into Ubuntu, the problem was resolved. The second time around the same thing happened, and I booted into Windows to fix the problem. I have done a search for known bugs on this issue, but none seem to relate to my exact problem. Is there a way to enable the wifi when it is grayed out? like in windows?Like I said this has only happened twice, but I had to boot into windows to fix the problem. I really want to delete windows all together, but if I have to keep it around awhile to fix this issue I guess I will.

Feb 8, 2011How do I get internet connection through mobile broadband (internet stick Nokia CS 15) for my laptop (Fujitsu Siemens) with encrypted hard disc (LVM)? I have set up LVM using Ubuntu 10.04 Alternate install.
Earlier when I installed the ordinary desktop version (Ubuntu 10.04 desktop) using no encrypted disc the internet connection worked fine. Before I installed the software from the internet stick an image appeared (Nokia Modem) on the desktop. I dubbel clicked the image and through the files that appeared I installed the software. After that I clicked the Eject Volume and after some input I had my connection.
But now I dont get that image on my desktop when the stick is plugged in. I can imagine that I have to mount the stick some how. I can further imagine that the encrypted hard disc through its protection now stop me from this action.

Ubuntu Networking :: Samsung R580 - Native Drivers Do Not Function And Having Identified The Driver Used By Win7 (net819xp.inf)
Oct 31, 2010I've recently bought a Samsung R580 laptop. It is now configured as a dual boot system with Ubuntu 10.10 and Windows 7 (64bit). The wireless network functions correctly under Win7, but I have encountered problems with Ubuntu. The native drivers do not function and having identified the driver used by Win7 (net819xp.inf) that works, I have tried to install it using ndisgtk, but get the message "incorrect hardware". I have followed the ndiswrapper howto carefully without being able to get the wireless network going.
View 4 Replies View RelatedServer :: CPU Queue Vs CPU % Busy
Dec 29, 2010Am wondering if looking at the CPU process queues, vs CPU% busy, are a better indication of whether an upgrade is needed.
Afterall, processes can still queue up to be processed even if "top" doesn't shown CPU 100%. Say if it's indicating 50% busy within the top output, it's only saying that 5 out of 10 times sampled, the CPU was busy. But a process may arrive to be processed at any time, and if it arrives just when the CPU is processing something it needs to wait in the queue. Am I making senses?
How many processes queued up would suggest an upgrade is required of the CPU? I've read online (believe it's Microsoft) that 2 is the figure.

Debian :: How To Flush Printer Queue
Mar 16, 2011I have an HP printer for my Lenny which has worked for some year. But I don't remember what method I used to install it. So this is one piece of the puzzle that I can't see. But like I said the printer works. One day I accidentally printed more than I had papers in the printer-machine. Then I kind of stacked a lot of print jobs in the queue out of frustration. So whenever I reboot the PC/Lenny then it waste some paper by printing things that got stuck in the printer queue. It's not very environmental this weird behavior.
So next time this happens how do I flush the Printer queue so Lenny doesn't remember what happened before the reboot? I followed these instructions earlier but it only switched one weird behavior with another weird behavior. So it didn't work for my Lenny, and I couldn't find any better solutions on the Internet.

View 3 Replies View RelatedUbuntu :: Can't Delete Job From Queue - Can't Print XP
Aug 23, 2010The Gnome Print Manager found the printer with no problems. The correct driver was available - so I installed it. The printer shows up when called by a print job I want to send. The queue pretends to process it. The queue states "completed." Then Nothing comes out of the printer. XP shows the print job as pending. Still nothing comes out of the printer. And I can't delete the job from the Ubuntu queue (because that lying SOB tells me the job is completed). I can't print from XP to that printer until I delete or cancel the Ubuntu job (from the XP queue) - or clear the XP print queue (by deleting spool files). Permissions on that printer are not an issue. Printing from Ubuntu to that printer worked OK on earlier versions of Ubuntu.
