• Enable/disable wireless interface in a bat file

  - by Herms

  Is there a way to enable/disable a wireless network interface via the command line (so I can put it in a bat file)? When I'm in the office I use a wired connection, but Windows still occasionally bugs me about my wireless connection not being connected (even though I turned off the option for notifying me when there's no connectivity). I'm guessing the only way to stop it from bugging me is to disable the interface, but I'd rather not have to go into the network settings every time I need to do so. I'd like to set up a bat file or a shortcut that I can use to enable/disable the wireless (preferably a single one that toggles the current state), and then just set up a keyboard shortcut for that. I just have no idea how to do so from the command line.

• emacs not load (.emacs) configuration file

  - by ant2009

  I am using emacs on ubuntu 9.04. I have my emacs configuration file in ~/.emacs.d directory. My emacs file is called .emacs I have some basic configuration. However, everytime I start emacs it never loads my configuration and I have to keep doing it manually using i.e. M-X Transient-mark-mode My emacs file is listed below: ;; Emac customization file path (add-to-list 'load-path "~/emacs.d") ;; Use font lock mode (global-font-lock-mode t) ;; Highlight cursor line (global-hl-line-mode t) ;; Highlight selected region (transient-mark-mode t) I want to add to this configuration instead of manually added entries. Many thanks for any advice,

• How do I create a Windows Batch file that does not show the Command Prompt when executed?

  - by Jake

  I have installed a ruby gem called Redcar, which is launched from the command line. When it runs, it steals the shell until it terminates, so I have to create a new shell window to continue doing command line work. The shell I'm using is the GITBash shell from MySysGit. I found a Redcar.bat file which is meant to launch Redcar as a shortcut, I presume, but I don't want the extra command prompt window to open whenever I launch the BAT file. How do I just run the BAT without seeing the prompt?

• Imagemagick apparently correctly configured, still won't work under IIS 7.5 + PHP 5.3.2

  - by Razor

  I have managed to get imagemagick working (tested using the command line example on their website) It also appears that the php extension is correctly installed: I can see it listed in my phpinfo(); list. However, when I try to run the following code: $im = new imagick( 'examples.jpg' ); $im->thumbnailImage( 200, 0); $im->writeImage( 'a_thumbnail.jpg' ); The execution stops at the second line, because it cannot find the thumbnailImage method. What I can think of is that some user doesn't have enough privileges to access/run something else, but I obviously cannot give user access to everything. Another possibility is that the PHP extension I'm using is not the suitable one for the latest imagemagick distribution.

• HAProxy and Intermediate SSL Certificate Issue

  - by Sam K

  We are currently experiencing an issue with verifying a Comodo SSL certificate on an Ubuntu AWS cluster. Browsers are displaying the site/content fine and showing all the relevant certificate information (at least, all the ones we've checked), but certain network proxies and the online SSL checkers are showing we have an incomplete chain. We have tried the following to try to resolve this: Upgraded haproxy to the latest 1.5.3 Created a concatenated ".pem" file containing all the certificate (site, intermediate, w/ and w/out root) Added an explicit "ca-file" attribute to the "bind" line in our haproxy.cfg file. The ".pem" file verifies OK using openssl. The various intermediate and root certificates are installed and showing in /etc/ssl/certs. But the checks still come back with an incomplete chain. Can anyone advise about anything else we can check or any other changes we can make to try to fix this? Many thanks in advance... UPDATE: The only relevant line from the haproxy.cfg (I believe), is this one: bind *:443 ssl crt /etc/ssl/domainaname.com.pem

• How to get the pid of a running process using a single command that parse the output of ps?

  - by Sorin Sbarnea

  I am looking for a single line that does return the pid of a running process. Currently I have: ps -A -o pid,cmd|grep xxx|head -n 1 And this returns the fist pid, command. I need only the first number from the output and ignore the rest. I suppose sed or awk would help here but my experience with them is limited. Also, this has another problem, it will return the pid of grep if the xxx is not running. It's really important to have a single line, as I want to reuse the output for doing something else, like killing that process.

• Can only bring up one of two interfaces

  - by mstaessen

  I'm having a bizarre issue with my HP Proliant DL 360 G4p server. It has two gigabit ethernet interfaces but I can bring up only one of them. This is starting to freak me out and that's why I turned here. I'm running the x64 ubuntu 11.10 server edition. lshw -c network shows that the second interface is disabled. I have no idea why ans how to enable it. $ sudo lshw -c network *-network:0 description: Ethernet interface product: NetXtreme BCM5704 Gigabit Ethernet vendor: Broadcom Corporation physical id: 2 bus info: pci@0000:02:02.0 logical name: eth0 version: 10 serial: 00:18:71:e3:6d:26 size: 100Mbit/s capacity: 1Gbit/s width: 64 bits clock: 66MHz capabilities: pcix pm vpd msi bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=tg3 driverversion=3.119 duplex=full firmware=5704-v3.27b, ASFIPMIc v2.36 ip=10.48.8.x latency=64 link=yes mingnt=64 multicast=yes port=twisted pair speed=100Mbit/s resources: irq:25 memory:fdf70000-fdf7ffff *-network:1 DISABLED description: Ethernet interface product: NetXtreme BCM5704 Gigabit Ethernet vendor: Broadcom Corporation physical id: 2.1 bus info: pci@0000:02:02.1 logical name: eth1 version: 10 serial: 00:18:71:e3:6d:25 capacity: 1Gbit/s width: 64 bits clock: 66MHz capabilities: pcix pm vpd msi bus_master cap_list ethernet physical tp 10bt 10bt-fd 100bt 100bt-fd 1000bt 1000bt-fd autonegotiation configuration: autonegotiation=on broadcast=yes driver=tg3 driverversion=3.119 firmware=5704-v3.27b latency=64 link=no mingnt=64 multicast=yes port=twisted pair resources: irq:26 memory:fdf60000-fdf6ffff If I try to ifup eth1, then I get $ sudo ifup eth1 Ignoring unknown interface eth1=eth1.

• rsync : Read input from a file and sync accordingly

  - by Dheeraj

  I have a text file which contains the list of files and directories that I want to copy (one on a line). Now I want rsync to take this input from my text file and sync it to the destination that I provide. I've tried playing around with "--include-from=FILE" and "--file-from=FILE" options of rsync but is is just not working I also tried pre-fixing "+" on each line in my file but still it is not working. I have tried coming with various filter PATTERNs as outlined in the rsync man page but it is not working. Could someone provide me correct syntax for this use case. I've tried above things on Fedora 15, RHEL 6.2 and Ubuntu 10.04 and none worked. So i am definitely missing something. Many thanks.

• Software for browsing/searching SQL Server transaction logs

  - by CodeByMoonlight

  I'd like to know whether there is any piece of software that will allow the browsing/searching of SQL Server transaction logs (any version). We've previously used Lumigent Log Explorer against SQL Server 2000 which fulfilled our need, but the product no longer exists and Lumigent's closest replacement doesn't appear to support SQL 2008 (according to the data sheet). I've discovered something called ApexSQL Audit which may fit the bill, but I'm wondering if anyone has any experience of it, how it compares with Log Explorer, and whether there are any good alternatives out there. Thanks :)

• Server downtime - are these APC warnings the cause?

  - by DisgruntledGoat

  Yesterday I had a problem with my dedicated server (Ubuntu 10.04, LAMP). It wasn't down per se, but running incredibly slowly as if we had a massive overload of visitors (though I don't think we did). It's running smoothly again now. I've been checking through log files etc to see if I can find any issues, the only strange thing is a bunch of these errors, occurring at about the same time as the downtime: [apc-warning] Unable to allocate memory for pool. in [file] on line 49. And a bit later on: [apc-warning] GC cache entry '[file1]' (dev=2056 ino=8988092) was on gc-list for 3601 seconds in [file2] on line 746. Could these errors indicate the cause of the server slowdown, or are they simply a result of the server being slow in the first place? What would be the solution?

• How do I read multiple lines from STDIN into a variable?

  - by The Wicked Flea

  I've been googling this question to no avail. I'm automating a build process here at work, and all I'm trying to do is get version numbers and a tiny description of the build which may be multi-line. The system this runs on is OSX 10.6.8. I've seen everything from using CAT to processing each line as necessary. I can't figure out what I should use and why. Attempts read -d '' versionNotes Results in garbled input if the user has to use the backspace key. Also there's no good way to terminate the input as ^D doesn't terminate and ^C just exits the process. read -d 'END' versionNotes Works... but still garbles the input if the backspace key is needed. while read versionNotes do echo " $versionNotes" >> "source/application.yml" done Doesn't properly end the input (because I'm too late to look up matching against an empty string).

• emacs AucTeX:Turn off auto-fill-mode inside a particular LaTeX environment

  - by Seamus

  I like using auto-fill-mode for hard line wrapping. However, when I'm making a big tabular in a .tex file, I like using align-current to have the table look somewhat like it would when printed. The difficulty is that if I have a table that is longer than the line width, auto-fill-mode breaks it, and then align-current can't put things to rights and gets confused. Is there a way to tell emacs that when I'm between the \begin and \end tags of a particular kind of environment (in this case, tabular), don't word wrap...

• Are there any USB flash drives or SD cards which use RAID or redundant storage for additional reliability?

  - by Luke Dennis

  I'm looking to get a fault-tolerant USB flash drive, which saves data to multiple independent locations, whether using RAID or some other means to back up data. Has a product like this ever been created, or are my only options to hack something together? (By the way: I'm aware that RAID doesn't prevent data corruption from software or the file system. I'm just looking for something that can handle one of the memory sticks going dead.)

• Adding text to the beginning and end of a number of files?

  - by John Feminella

  I have a number of files in a directory hierarchy. For each file, I'd like to add "abcdef" to the beginning, on its own line, and "ghijkl" to the end, on its own line. For example, if the files initially contained: # one/foo.txt apples bananas # two/three/bar.txt coconuts Then afterwards, I'd expect them to contain: # one/foo.txt abcdef apples bananas ghijkl # two/three/bar.txt abcdef coconuts ghijkl What's the best way to do this? I've gotten as far as: # put stuff at start of file find . -type f -print0 | xargs -0 sed -i 's/.../abcdef/g' # put stuff at end of file find . -type f -print0 | xargs -0 sed -i 's/.../ghijkl/g' but I can't seem to figure out how what to put in the ellipses.

• Exported csv file is not in right lining with pgadmin

  - by user938363

  We exported a pg 9.3 table to csv file in pgadmin. The problem is that from about 10th line, the lining of the columns were messed up and did not line up correctly with the columns above. We tried a few times and every output has the same problem. We follow the instruction on http://www.question-defense.com/2010/10/15/how-to-export-from-pgadmin-export-pgadmin-data-to-csv for export. The only difference that UTF8 is selected instead of localcharset. What's the right way to export csv in pg?

• What are the small details Windows and Linux users will trip on when using OSX for the first time?

  - by badp

  Like any other Apple product, OS X prides itself on the little details. When, earlier last week, I used my professor's Mac briefly to give a quick project presentation (mine decided to do a chkdsk at the wrong time, heh), I got the distinct feeling some were put intentionally to make the uninitiated look stupid. What are the small usability details that Windows and Linux users will trip on when their Mac using friend lend them their beloved Mac for some quick web browsing?

• Dropbox.py on RHEL 6

  - by Timothy R. Butler

  I'm trying to run a headless install of Dropbox on RHEL 6. The daemon seems to be running, but when I try to use Dropbox's associated dropbox.py tool to control the daemon, it fails to run with the following error: Traceback (most recent call last): File "./dropbox.py", line 26, in <module> import locale File "/usr/lib64/python2.6/locale.py", line 202, in <module> import re, operator ImportError: /home/dropbox/.dropbox-dist/operator.so: undefined symbol: _PyUnicodeUCS2_AsDefaultEncodedString I'm running the current RHEL build of Python 2.6: root@cedar [/home/dropbox/.dropbox-dist]# rpm -qv python python-2.6.6-29.el6_3.3.x86_64 (I'm not sure if this would be better suited to Stack Overflow since it is on the verge of being a programming issue, but since I'm trying to use a program straight from Dropbox, I placed it here.)

• Proccess of carrying out a BER Test

  - by data

  I am subscribed to an ISP supplying a 3meg ADSL line. Lately (for the last 4 weeks) speeds have dropped from the usual average downstream speed of ~250kbps to just 0.14Mbps (according to speedtest.net) and employees are complaining about lack of access to the server. I have been calling customer support and logging calls for the last 3 weeks, but they have been unable to determine the source of the problem other carrying out a few bitstream tests and checking the DHCP renewal times. I am going to call back and suggest carrying out a BER test. What type of equipment is needed to carry out this test? I have access to a wide range of Cisco networking equipment. Other: We dont need a leased line as there are less than ten employees.

• Setting http_proxy for Chromium in shell

  - by iceboal

  In order to set proxy in Chromium browser, one needs to go to Settings ? Under the Hood ? Change Proxy Settings ? Network Proxy. It's too complicated. How do I set http_proxy in shell? I've tried export http_proxy=http://127.0.0.1:8080/ But it doesn't seem to work. Also, if you only want to set the proxy on the Chromium browser -- not your entire network -- the command line is the only way to set the proxy just for the browser. How can one set the proxy on Chromium -- using the command line -- to solve this problem?

• How can I make the NetworkManager work?

  - by Yang Jy

  I am running a version of RHCE6 on my laptop, and lately I've been trying various stuff about network configuration through command line. Last night, I tried removing the NetworkManager using "yum remove NetworkManager" from the system, so that I could have more control of the network through the command line. But the result is, I didn't manage to configure the wireless connection through wpa_supplicant, and I need wireless connection during my travel to another place. So I need the wireless function back as soon as possible. I typed " yum install NetworkManager", some version installed, but I don't get to have an icon on the taskbar, and of course, the network doesn't work. The package I previously removed(about 24MB) was much larger that the one I just installed(about 2MB), so I think some dependencies must be missing. How could I install all these dependencies? Please help!

• Creating a Scheduled Task that runs forever on Windows XP

  - by Mike Fiedler

  When I create a scheduled task, I do so via command line: schtasks.exe /Create /TN "startup-script" /TR "C:\startup.bat" /RU taskuser /RP taskpasswd /SC ONLOGON The idea is that this task run forever. The batch opens a java process that is never meant to end. I've used ONLOGON, as the machine auto-logs in as taskuser. All this works fine, for about 72 hours, after which the Duration flag kicks in and ends the process. Windows XP doesn't have the /DU flag on command line - is there an alternative method to creating a task that is meant to run from a system startup (doesn't even require logon) and runs forever, without touching a GUI?
