• Bash vs. Gnu screen : Replace Ctrl-A with Ctrl-Shift-A

  - by Stefan Lasiewski

  I'm a new user to GNU Screen. I've been using Bash for a very long time, and I want to give GNU Screen a try. As you know, GNU Screen uses 'C-a' (Control-A) as as the command character. Trouble is, this interferes with the Line Editing feature in Bash (and GNU Readline), because Control-A in Bash will Move to the start of the line." I know I can set the Command Character to another key sequence, like "^Q" or "``" (Backtick), but I have trouble finding another key sequence which isn't already in use (^Q is used by the terminal, backtick is used when writing shell scripts). It appears that the Command Character may only be one or two characters in length. Can I set the GNU Screen control character to be something like "Control-Shift-A"? (I can't use more then one hyperlink yet, so I cannot link to the Bash documentation)

• award phoenix bios not recognizing my sata hdd.

  - by josh

  What am I doing wrong? I have a custom built comp with a Fatal1ty AA8XE mobo. It has 4 SATA ports and one IDE port. When i first got it, I had a really hard time putting in more than one hard drive. Right now i have one 120gb IDE HDD on master and my DVD+-RW on slave connected to the one IDE spot on the mobo. I ripped a bunch of movies and filled up my HDD, so I got a WD 80gb SATA drive. I plugged it into SATA1 and hooked up the power, turned on comp, went into bios. The only thing in any option in any of the menues in this crazy lookin bios is a thing that says "SATA mode". i put it on IDE, set it so PATA is primary, SATA is secondary. booted up my comp, nothin. Not recognizing the SATA. I went back into the bios and checked it all again. I saw that it says SATA2 and SATA4 are the secondaries so i put it on SATA2, booted, nothing, same with SATA4, same with SATA3, all same as SATA1. Bios and wt os are not recognizing the drive as being there at all. I even downloaded and printed the almost 100 page manual for the mobo, read the entire thing, and still can't figure it out. I know there are a lot of people out there smarter than me when it comes to computers. So please, somebody, anybody, please tell me something that I'm not seeing. Some setting somewhere that I didn't configure right. There is something, obviously, but I can't find it. As far as i can tell, everything is set perfectly fine for my 120gb to be the master and the SATA to be the slave. I don't know what I'm doing wrong but I'm seriously about to throw this computer out the window. thankyou in advance to whoever attempts to help.

• Windows 8 Start Screen very slow after Guest Additions

  - by Renan

  I installed Windows 8 Release Preview on a VirtualBox VM, and it worked correctly. Then I installed the Guest Additions to get the correct resolutions. Now, the Start screen is very slow, takes a long time to scroll and doesn't respond well to clicks. I believe it's not my host, as it's a good machine (i7 CPU, 6 GB of RAM) and this specifically starts to happen after installing the Guest Additions. The task manager doesn't show anything wrong (i.e. no processes pegging the CPU). Any suggestions?

• Beep code for Dell Poweredge T105

  - by Thomas

  I can't start my Poweredge T-105 just after two years. It does not display any on monitor but blue lights on 3 & 4 of system case. And it repeatedly beeps. At first, it beeps 1-3-3 and then repeats 1-1-3-4. As far as I can search on the net, Dell's beep code is 3 digit. So do I have to consider the beep code for my error is 1-3-3? Unfortunately, my warranty expired last year so any hint will be appreciated.

• Windows Media Player - Display JPEG cover art for FLAC files

  - by pelms

  I got WMP 12 (on Windows 7 RC1) to play FLAC files by installing the Ogg Vorbis/FLAC, Direct Show filters, but WMP does not display the embedded cover artwork. After experimenting I found that it will display the cover art if it is embedded in PNG format, but up to now I've used JPEG for all my FLAC files. Rather than re-tagging all my files, does anyone know a way to get WMP 12 to display JPEG embedded cover art?

• Protect Section in Word without limiting formatting in unprotected sections

  - by grom

  Steps to create protected section (in Word 2003): Insert - Break... Choose Section break, Continuous Tools - Protect Document... Enable 'Allow only this type of editing in the document' in editing restrictions In the drop down select 'Filling in forms' Click on 'Select sections...' and uncheck the unprotected sections (eg. Section 2) Click 'Yes, Start Enforcing Protection' and optionally set a password. Now go to the unprotected section and in the Format menu options like 'Bullets and Numbering...' and 'Borders and Shading...' are greyed out. How can you protect a section without limiting the features that can be used in the unprotected section?

• Fastest SFTP client

  - by Stan

  Protocol: SFTP (port 22) I've tested CuteFtp, FileZilla, SecureCRT and several others. Looks like CuteFTP has the best throughput, usually 200%-400% than others. I've read something about SecureFtp may have slower rate from here. Can anyone explain why CuteFtp has better throughput? And, is there any other FTP client even faster than CuteFtp? Thanks a lot!

• Can't view other computers on Network

  - by Darkart

  Systems: My Machine: Windows 7 Ultimate connected through ethernet into router Her Machine--Other Machine: Windows 7 Ultimate connected through wireless Router:F5D8236-4 N Wireless Router Version 1 Firmware: 2.01.03 (Apr 28 2009) ISP: Comcast Problem: I can not view the "Other Machine" on the network at all. I opened command prompt and ran net view and saw the pc name. I tried pinging the pc and it times out. Went inside the router and tried viewing the computer on the DHCP list and it can not be seen. I restored the router back to default settings and firmware and completely reset the modem and router, and created home group. I went to the other machine to configure home group settings and made sure that both PC's had identical settings. She was able to see my machine but I could not see hers. I restarted both machines and now we cant see each other at all. Also her PC ("Other Machine") had exclamation mark in the wireless icon but was connected just fine. There is no firewalls on currently or anti-virus enabled, and still can not see each other. Right now I am checking for updated drivers for the wireless card, but my question is could it be the router or something hardware related? I have went through all the settings in the Home group and visited most FAQ's and still no luck. Also as it stands I can not view her machine inside the router DHCP Client List :(

• sudo apt-get moo and other easter eggs in Linux

  - by Arkapravo

  I came across this command while dabbling in Ubuntu 9.10: sudo get-apt moo acer@acer:~$ sudo apt-get moo (__) (oo) /------\/ / | || * /\---/\ ~~ ~~ ...."Have you mooed today?"... Which most surprisingly "made a MOO". (How unfortunate for the cows). Does anyone else know of funny command line easter eggs in their flavour of Linux (Fedora, Slackwire, Mandriva, Solaris, Suse, etc)?

• Does the Win XP/7 dual boot "missing restore points" problem apply to systems with separate hard disks for each O/S?

  - by Robert Oschler

  I'm in the process of installing Windows 7/64 on a system with Windows XP/32 on it. During my research, I read about a problem that occurs in the dual boot scenario where Windows XP deletes Windows 7's restore points when it accesses the Windows 7 volume: http://support.microsoft.com/kb/926185 I found a workaround but it seems pretty painful since it appears to involve using the registry to make the Windows 7 volume appear invisible or "offline" to Windows XP, making sharing disk data between the two O/S annoying since you have to use something like an external storage device to get it done: http://www.vistax64.com/tutorials/127417-system-restore-points-stop-xp-dual-boot-delete.html I was wondering if this problem only occurs with systems that have both O/S installed on the same physical hard drive (in different partitions)? In my case, I will have each O/S on a completely separate physical hard drive. Any other tips would be appreciated. -- roschler

• screen resume works on top of VPN

  - by michael

  I connect to my network using VPN. I have screen running and 'ssh' to a server. I then kill my shell and I was able to 'resume' by 'screen -r'. This works as expect. But when I disconnect VPN and re-connect VPN, and type 'screen -r' again. I was not able to get my last screen again. And I see "Write failed: Connection reset by peer46.11 MiB | 642 KiB/s" in the screen. Can you please tell me if it possible to reconnect 'screen' if my VPN is disconnect. Thank you.

• mplayer audio desync

  - by geek

  I have and avi file and an ac3 file that contains an alternate audio stream. I run mplayer like: mplayer -audiofile foo.ac3 bar.avi mplayer takes the audio stream from the ac3 file as expected, but when I try to scroll the video using arrows or pgup/pgdown keys, the audio gets desynced: mplayer just starts playing the audio stream from the beginning. Do I have to pass any additional command line arguments in order to make it scroll properly without desyncing audio?

• Acer Aspire 1360 Recovery CDs

  - by John

  I have replaced a dead hard disk in an out of warranty Acer Apire 1360 laptop. The two recovery CDs I have dont appear to be bootable, they just contain .hdd and .ghs (image?) files. On the original broken hard drive there was a hidden partition which could be invoked by pressing alt+f10 when booting. You would then be prompted for the 2 recovery CDs to perform the restore. Obviously the new hard drive does not contain the hidden Acer recovery partition. This being the case, how do I go about restoring Win XP? The 2 CDs are called Aspire 1360/1520 Serires Recovery CD Disk 1 of 2 and 2 of 2. Am I missing a futher bootable recovery CD? Can anyone confirm how many restore CDs originally came with the laptop.

• WAMP vhost issues with all vhost pointing to the first vhost statement

  - by Rick

  I am trying to setup vhosts in WAMPSERVER and I am running into an issue where all sites are pointing to the first vhosts and not delegating properly. Has anyone had this issue? Here is my setup. In windows hosts file: 127.0.0.1 siteabc.local 127.0.0.1 sitexyz.local In httpd-vhosts.conf: <VirtualHost 127.0.0.1> DocumentRoot "C:\Users\Rick\Documents\Projects\siteabc" ServerName siteabc.local ErrorLog "logs/siteabc-error.log" CustomLog "logs/siteabc-access.log" common <Directory "C:\Users\Rick\Documents\Projects\siteabc"> Options Indexes FollowSymLinks AllowOverride all Order Deny,Allow Allow from all </Directory> </VirtualHost> <VirtualHost 127.0.0.1> DocumentRoot "C:\Users\Rick\Documents\Projects\sitexyz" ServerName sitexyz.local ErrorLog "logs/sitexyz-error.log" CustomLog "logs/sitexyz-access.log" common <Directory "C:\Users\Rick\Documents\Projects\sitexyz"> Options Indexes FollowSymLinks AllowOverride all Order Deny,Allow Allow from all </Directory> </VirtualHost> <VirtualHost 127.0.0.1> DocumentRoot "C:\Users\Rick\Documents\Projects" ServerName localhost ErrorLog "logs/localhost-error.log" CustomLog "logs/localhost-access.log" common <Directory "C:\Users\Rick\Documents\Projects"> Options Indexes FollowSymLinks AllowOverride all Order Deny,Allow Allow from all </Directory> </VirtualHost> Ok so from this setup going to siteabc works...but going to sitexyz, it still goes to siteabc. Not sure what I did wrong here. Thanks for looking.

• How to go to a website on a shared server by its ip address?

  - by user1502776

  I have a few questions, please help: Fist, I can access google search just by typing http://74.125.224.211 because this is the ip address returned by nslookup. However, I could not do so with ip addresses returned from www.yahoo.com. How do I go to yahoo search page by its ip ? Another example, http://www.allaboutcircuits.com will resolve to 68.233.243.63 by DNS server, but if I go to http://68.233.243.63 I got "Hello world!" , lol ! Second, for some reason, there is something wrong with DNS resolvers with my web hosting service (it will not be fixed !!). So command like, get_file_contents("http://www.allaboutcircuits.com"); will return php_network_getaddresses: getaddrinfo failed: Name or service not known How do I get around this with IP address , 68.233.243.63 I mean somehow attach the HTTP hostname parameter to get_file_contents() ? I would like to solve this on my own side (in my code), no troubleshooting/adjustment will be done by server admin.

• Why does limiting my virtual memory to 512MB with ulimit -v crash the JVM?

  - by Narinder Kumar

  I am trying to enforce maximum memory a program can consume on a Unix system. I thought ulimit -v should do the trick. Here is a sample Java program I have written for testing : import java.util.*; import java.io.*; public class EatMem { public static void main(String[] args) throws IOException, InterruptedException { System.out.println("Starting up..."); System.out.println("Allocating 128 MB of Memory"); List<byte[]> list = new LinkedList<byte[]>(); list.add(new byte[134217728]); //128 MB System.out.println("Done...."); } } By default, my ulimit settings are (output of ulimit -a) : core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 31398 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 31398 virtual memory (kbytes, -v) unlimited file locks (-x) unlimited When I execute my java program (java EatMem), it executes without any problems. Now I try to limit max memory available to any program launched in the current shell to 512MB by launching the following command : ulimit -v 524288 ulimit -a output shows the limit to be set correctly (I suppose): core file size (blocks, -c) 0 data seg size (kbytes, -d) unlimited scheduling priority (-e) 0 file size (blocks, -f) unlimited pending signals (-i) 31398 max locked memory (kbytes, -l) 64 max memory size (kbytes, -m) unlimited open files (-n) 1024 pipe size (512 bytes, -p) 8 POSIX message queues (bytes, -q) 819200 real-time priority (-r) 0 stack size (kbytes, -s) 8192 cpu time (seconds, -t) unlimited max user processes (-u) 31398 virtual memory (kbytes, -v) 524288 file locks (-x) unlimited If I now try to execute my java program, it gives me the following error: Error occurred during initialization of VM Could not reserve enough space for object heap Could not create the Java virtual machine. Ideally it should not happen as my Java program is only taking around 128MB of memory which is well within my specified ulimit parameters. If I change the arguments to my Java program as below: java -Xmx256m EatMem The program again works fine. While trying to give more memory than limited by ulimit like : java -Xmx800m EatMem results in expected error. Why the program fails to execute in the first case after setting ulimit ? I have tried the above test on Ubuntu 11.10 and 12.0.4 with Java 1.6 and Java 7

• How to fix corrupted filesystem (shows as RAW) in USB device?

  - by Erico Yan

  I would like to ask if you know how to fix a corrupted USB? I've tried the diskpart command but it didn't work. The media is write protected. Do you have any idea that is much better? I need to fix it because I have important files in my flash drive. I really need to retrieve it. I saw that the file system is seen as RAW and is unaccessible. I tried error checking, but it requires you to format it. I tried data recovery software but all files come out corrupted. My USB is Imation 4GB. Any suggestions?

• Making Windows Explorer to Search WebDAV Server using DASL

  - by user124209

  I am trying to setup search in a WebDAV repository in IIS 6 on Windows Server 2003 R2. I successfully configured WebDAV in IIS and enabled my repository indexing as described in Searching WebDAV Directories (IIS 6.0) I have verified that search is now supported by my WebDAV server, in OPTIONS request I can see DASL support: DASL: <DAV:sql> DAV: 1, 2 Public: OPTIONS, TRACE, GET, HEAD, DELETE, PUT, POST, COPY, MOVE, MKCOL, PROPFIND, PROPPATCH, LOCK, UNLOCK, SEARCH Allow: OPTIONS, TRACE, GET, HEAD, DELETE, COPY, MOVE, PROPFIND, PROPPATCH, SEARCH, MKCOL, LOCK, UNLOCK I connected to my WebDAV server from a client computer, which is Windows 8.1 and WebDAV is working well. I mounted a drive and connected using \\server@port\DawWWWRoot as described here. However my client computer, which is Windows 7, does not generate any search request. I have captured requests using Fiddler tool and found that Windows Explorer is not sending any search requests, instead it is sending a PROPFIND and downloading files. How do I make Windows Explorer to send SEARCH request to my WebDAV server?

• Different routing rules for a particular user using firewall mark and ip rule

  - by Paul Crowley

  Running Ubuntu 12.10 on amd64. I'm trying to set up different routing rules for a particular user. I understand that the right way to do this is to create a firewall rule that marks the packets for that user, and add a routing rule for that mark. Just to get testing going, I've added a rule that discards all packets as unreachable: # ip rule 0: from all lookup local 32765: from all fwmark 0x1 unreachable 32766: from all lookup main 32767: from all lookup default With this rule in place and all firewall chains in all tables empty and policy ACCEPT, I can still ping remote hosts just fine as any user. If I then add a rule to mark all packets and try to ping Google, it fails as expected # iptables -t mangle -F OUTPUT # iptables -t mangle -A OUTPUT -j MARK --set-mark 0x01 # ping www.google.com ping: unknown host www.google.com If I restrict this rule to the VPN user, it seems to have no effect. # iptables -t mangle -F OUTPUT # iptables -t mangle -A OUTPUT -j MARK --set-mark 0x01 -m owner --uid-owner vpn # sudo -u vpn ping www.google.com PING www.google.com (173.194.78.103) 56(84) bytes of data. 64 bytes from wg-in-f103.1e100.net (173.194.78.103): icmp_req=1 ttl=50 time=36.6 ms But it appears that the mark is being set, because if I add a rule to drop these packets in the firewall, it works: # iptables -t mangle -A OUTPUT -j DROP -m mark --mark 0x01 # sudo -u vpn ping www.google.com ping: unknown host www.google.com What am I missing? Thanks!
