  • Cron: job starts but doesn't complete

    - by Guandalino
    I have a problem with a cron job which starts but doesn't complete. Running the command manually works fine. I already read the page about cron issues and solutions here on AskUbuntu, tried the proposed solutions but didn't find an answer working in my case. I'm using Ubuntu 12.04. $ crontab -e SHELL=/bin/bash # otherwise it would be /bin/sh 59 16 * * * /bin/duply calendar backup > /tmp/duply.log Btw, the cron file ends with an empty line, as someone pointed out. Once the job has "finished"...: $ cat /tmp/duply.log Start duply v1.5.7, time is 2012-06-22 16:59:01. Instead, running manually the script it works correctly and gives this output: Start duply v1.5.7, time is 2012-06-22 17:06:39. [cut] ... here is a long output generated by duply. ... and yes, files have been backed up. [cut] --- Finished state OK at 17:06:42.581 - Runtime 00:00:03.170 --- I also tried to restart the cron daemon (sudo service cron restart) but nothing changed. Do you have any suggestion to fix the issue?

  • plesk 9 spamassassin server wide blacklist via cron?

    - by Kqk
    hi, we're running ubuntu 8.04 LTS and plesk 9.2 our simple task is to set up a periodic black list for spamassassin, e.g. using this script .. #!/bin/sh #! Script by AJR to update local spamassassin rules cd /tmp wget -c http://www.stearns.org/sa-blacklist/sa-blacklist.current mv sa-blacklist.current local.cf -f mv local.cf /etc/mail/spamassassin -f rm local.cf -f /etc/init.d/psa-spamassassin restart now, this script runs fine, but plesk doesn't seem to recognize the blacklist in its GUI. which is annoying, especially because plesk itself writes to /etc/mail/spamassassin/local.cf. i wasn't able to find out the secret place, where plesk distinguishes between entries in local.cf added via GUI and command line. any help is appreciated! thanks.

  • cannot mount root filesystem on 10.04

    I tried to apply the recommendation of question: Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0) After running that command: sudo mount --bind /dev /mnt/dev I get this error message: mount: mount point /mnt/dev does not exist fdisk -l returns /dev/sda1 /dev/sda2 /dev/sda5 do I need to mount sda2 and sda5?

  • Raspberry Pi stuck at splash screen

    - by Matthew
    I have a raspberry pi and I am stuck at the splash screen. In the top right of the screen there is an image of a Raspberry. When I first power on the device, I get the colored screen, and then I get the image of the raspberry followed by a white cursor which quickly freezes or disappears. I put on the debian version of wheezy that allows java. (the soft float version) Any assistance would be greatly appreciated. BTW I did have it working at one point in time and all I did was go to the terminal (logged out of the GUI) and did a shutdown -h now command. But since then I've even started with a brand new version of the image and it is still not working. Oh and I did try the same SD card with a version of arch linux and it worked fine.

  • Cut in excel doesn't work, and copying tables from one program to another returns text

    - by Kristina
    My excel 2007 on Windows 7 operating system seems to have a probelm with regular cut function. when I highlight cells I want to cut and press cut (either on keyboard shortcut Ctrl+x, Home menu cut command, or from the right-click menu) cells start flashing for a split second and after that they only turn normal. When I want to paste them, they past as if copy function was used. If I try to rightclick to use function "insert cut cells" it is not one of the offered options at all. On my home computer I have same combination, Excel 2007 on windows 7 and it works just fine. COuld the problem be due to 64-bit win7 version at my job, and 32-bit version at home? Another problem is when I copy table from excel to word, in word pasting results in unformatted text instead of table as it was in excel. Did someone have such problems and can offer a solution? Thanx a lot.

  • Why aren't Heroku syslog drains logging to rsyslogd?

    - by Benjamin Oakes
    I'm having a problem using syslog drains as described in https://devcenter.heroku.com/articles/logging. To summarize, I have an Ubuntu 10.04 instance on EC2 that is running rsyslogd. I've also set up the security groups as they describe, and added a syslog drain using a command like heroku drains:add syslog://host1.example.com:514. I can send messages from the Heroku console to my rsyslogd instance via nc. I see them appear in the log file, so I know there isn't a firewall/security group issue.  However, Heroku does not seem to be forwarding log messages to the server that heroku drains lists. I would expect to see HTTP requests, Rails messages, etc. Is there something else I can try to figure this out? I'm new to rsyslogd, so I could easily be missing something.

  • "Recipient address rejected" when sending an email to an external address with sendgrid

    - by WJB
    In postfix, I'm using relay_host to send an email to an external address using sendgrid, but I get an error about local ricipient table when sending an email from my PHP code. This is my main.cf in /postfix/ ## -- Sendgrid smtp_sasl_auth_enable = yes smtp_sasl_password_maps = static:username:password smtp_sasl_security_options = noanonymous smtp_tls_security_level = may header_size_limit = 4096000 relayhost = [smtp.sendgrid.net]:587 This is the error message from the log: postfix/smtpd[53598]: [ID 197553 mail.info] NOQUEUE: reject: RCPT from localhost[127.0.0.1]: 550 5.1.1 Recipient address rejected: User unknown in local recipient table; from=<[email protected]> to=<[email protected]> proto=ESMTP helo=<localhost.localdomain> One interesting thing is when I use "sendmail [email protected]" from the command line, the email is delivered successfully using SendGrid. I think it's because this uses postfix/smtp instead of postfix/smtpD the log for this says, postfix/smtp[18670]: [ID 197553 mail.info] AAF7313A7E: to=, relay=smtp.sendgrid.net[50.97.69.148]:587, delay=4.1, delays=3.5/0.02/0.44/0.18, dsn=2.0.0, status=sent (250 Delivery in progress) Thank you

  • Speed up loading of test results from builds in Visual Studio

    - by Jakob Ehn
    I still see people complaining about the long time it takes to load test results from a TFS build in Visual Studio. And they make a valid point, it does take a very long time to load the test results, even for a small number of tests. The reason for this is that the test results is not just the result of the test run but also all the binaries that were part of the test run. This often also means that the debug symbols (*.pdb) will be downloaded to your local machine. This reason for this behaviour is that it letsyou re-run the tests locally. However, most of the times this is not what the developer will do, they just want to know which tests failed and why. They can then fix the tests and rerun them locally. It turns out there is a way to load only the test results, which is much faster. The only tricky bit is to find the location of the .trx file that is generated during the build. Particularly in TFS 2010 where you often have multiple build agents, which of corse results in different paths to the trx file. Note: To use this you must have read permission to the build folder on the build agent where the build was executed. Open the build result for the build Click View Log Locate the part where MSTest is invoked. When using test containers, it looks like this:   Note: You can actually search in the log window, press Ctrl+F and you will get a little search box at the bottom. Nice! On the MSTest command line call, locate the /resultsfileroot parameter, which points to the folder where the test results are stored Note that this path is local for the build server, so you need to replace the drive letter with the server name: D:\Builds\Project\TestResults to \Project\TestResults">\\<BuildServer>\Project\TestResults Double-click on the .trx file and you will notice that it loads much faster compared to opening it from the build log window

  • Xubuntu 14.04 with Compton, strange screen tearing, only when playing videos though (advice needed)

    - by LinuxDudester
    Hello beloved community, Yet again I am in need of your great expertise. I ran into a very strange issue and just can't wrap my mind around it. I'm running Xubuntu 14.04 exclusively, with Compton installed. The OS runs great and I have absolutely no screen tearing when I move my windows around, scroll in my web browser, work in Gimp or Photoshop (wine) or even when I play very graphic demanding games, like Metro Last Light, Euro Truck Driver 2 and so on. There's not a tiny bit of tearing to see, but as soon as I play videos, in xbmc, vlc or parole media player the tearing begins (strangely enough this does not apply to youtube videos). I followed all available workarounds on askubuntu and the ubuntu forum,like the 50-xserver-command.conf, startx /etc/X11/Xsession /usr/bin/xbmc-standalone -- -bs or libsdl1.2debian fix and many more, but to no avail. I also tried the Open Source Nouveau display drivers as well, but for some odd reason they don't work so great on my system or at least with my graphics card. Even with Compton installed and configured, I have an extreme amount of screen tearing, as soon as I switch to the proprietary Nvidia drives the screen tearing is gone completely, except for the video playback with xbmc, vlc or parole media player. System info for your reference: OS: Xubuntu 14.04 Linux-x86_64 - Processor: Intel Core i7-4770S CPU @ 3.10GHz - Ram: 16 GB - GeForce GT 750M 1024 MB - Nvidia Driver: 331.38 Has anyone experienced such an odd issue or do you have any advice on how I could fix this? I would appreciate any help! Have a nice day!

  • Unable to connect to mysql through JDBC connector through Tomcat or externally

    - by Stefan Kendall
    I've installed a stock mysql 5.5 installation, and while I can connect to the mysql service via the mysql command, and the service seems to be running, I cannot connect to it through spring+tomcat or from an external jdbc connector. I'm using the following URL: jdbc:mysql://myserver.com:myport/mydb with proper username/password, but I receive the following message: server.com: Communications link failure The last packet sent successfully to the server was 0 milliseconds ago. the driver has not received any packets from the server. and tomcat throws: com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: Communications link failure The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server. sun.reflect.NativeConstructorAccessorImpl.newInstance0(Native Method) sun.reflect.NativeConstructorAccessorImpl.newInstance(NativeConstructorAccessorImpl.java:57) Which seems to be the same issue as if I try to connect externally.

    Hello all, I'm trying to setup Ubuntu on an old PC. I ran the following command, lspci, in order to get info on the wireless card installed. 00:0a.0 Ethernet controller: Marvell Technology Group Ltd. 88w8335 [Libertas] 802.11b/g Wireless (rev 03) Does anyone know where I can get drivers for this card/chip? And also, how to install (I'm rather new to linux). Also, I'm sure the card is working because I just formatted over xp, and everything was working well. Thanks in advanced!

  • How can I limit the upload/download bandwidth on my CentOS server?

    - by Dan Nestor
    How can I limit the upload and download bandwidth on my CentOS server? This is a box with a single interface, eth0. Ideally, I would like a command-line solution (I've been trying to use tc), something that I could easily switch on and off in a script. So far I've been trying to do something like tc filter add dev eth0 protocol ip prio 50 u32 police rate 100kbit burst 10240 drop but I'm obviously missing a lot of knowledge and information. Can somebody help with a quick one-liner? Many thanks, Dan

  • Python multithreading not working on VPS server

    - by Sabirul Mostofa
    I am running an python multithreaded application with multiple processes which scrapes data from some websites. While running on my localhost It works great, but on the vps server I am using( Centos 5.8, 2.6 GHZ with 4 cores) performs very slow. From the nethogs command I get the network usage too low. I get around 8KBps with 15 threads. On other hand, in my PC I get the usage around 100-120KBPS. I have read about the Python GIL and threading limitations. It seems GIL never releases the lock on the VPS though it should while doing I/0 Is there any configuration in the VPS that I need to change for the threading to work properly?

  • Forgot to unmount/eject external hard drive, lost moved files. Mac OS X

    - by balupton
    So I was using my Mac with my external hard drive connected via USB. I moved about 10 GB of data to it (via drag and drop while holding down the Command key to move the files rather than to copy them). They moved to the drive all right, but as I was having some issues and the Finder crashed after the transfer, I was unable to eject the volume and later everything froze so I had to do a hard restart (hold the power button). When I remounted the volume (plugged the external hard drive back in) it no longer had any of the files which I moved onto it. As it was a lot of data, how can I recover these files?

  • How to maintain symlinks in linux file manager?

    - by MountainX
    I want to use symlinks extensively. However, if I move the target file, the symlink becomes broken (unlike on Windows). That's not acceptable to me, so I either need a solution or I won't be able to use symlinks the way I wish to. Is there a solution that will work with Dolphin file manager? A command line solution is described on commandlinefu. In summary, it is something like one of these: lmv(){for a in ${@:1:$(expr $#-1)};do [ -e "$a" -a -e "${@:$#:1}" ] && mv "$a";"${@:$#:1}" && ln -s "${@:$#:1}"/"$(basename "$a")";"$(dirname "$a")";done} lmv(){for a in ${@:1:$(expr $#-1)};do [ -e "$a" -a -e "${@:$#}" ] && mv "$a";"${@:$#}" && ln -s "${@:$#}"/"$(basename "$a")";"$(dirname "$a")";done} But about half the time I'm using a file manager (Dolphin), so I need a complete solution to this problem. Is a solution available for a GUI file manager? EDIT: The context of this question is that I'm searching for an alternative to hardlinks. I previously asked this question about the pitfalls of hardlinks.

  • Is there a tool to copy a folder using shadow copy?

    - by Borek
    Is there a tool similar to Robocopy or TeraCopy that would do a "shadow copy" of a folder? I'm not sure if this is technically possible on Windows 7 but what I'd like to find a utility that, when I execute the "copy" command, would create a fixed copy of that folder at that given time and then copy the result over to another location. What I'd like to achieve are consistent copies of folders that might be currently in use. Is this possible on Windows? Is there any user friendly utility to help with this?

  • How can I allow a linux subversion user to only execute svnserve?

    - by sbleon
    I've got a user that I'd like to only be able to use subversion. We like to use svn+ssh:// URLs sometimes (for public keys and whatnot), so I need them to be able to connect over ssh and run only the svnserve command. When using a svn+ssh URL, svn ssh'es in and passes the arguments "-c svnserve -t". I wrote a custom shell as follows to filter the commands that can be run. This works, but it's not passing the input to svnserve, so when I try to "svn up" I get "svn: Connection closed unexpectedly". #!/bin/bash if [ "$1" == "-c" ] && [ "$2" == "svnserve" ] && [ "$3" == "-t" ] && [ "$4" == ""] ; then exec svnserve -t else echo "Access denied. User may only run svnserve." fi

  • Can't seem to install the correct version of PHP, using apt-get install

    - by Mark Tomlin
    I'm using Ubuntu 11.04 LTS server, it's a new install on a VPS box from MediaTemple (their ve server). I'm trying to install PHP 5.4.3 on this box, but I'm having a common problem not matter what version I get. I'm trying to get the php-cgi process, so I do the command apt-get install php-cgi and that installs, but does not provide me with the php-cgi executable. I need this so that I can run php-cgi -b 127.0.0.1:9000 and have it has a FastCGI process for my nginx install. Any idea what I can do to get this to work, bonus points if you can get this to work with PHP 5.4.3, because all I can seem to install is PHP 5.3.5.

  • Restoring GRUB2 on Software RAID 0 after Windows 7 wiped it using LiveCD

    - by unknownthreat
    I have installed Ubuntu 10.10 on my system. However, I need to install Windows 7 back, and I expect that it would alter GRUB and it did. Right now, my partition on my Software RAID 0 looks like this: nvidia_acajefec1 is Ubuntu 10.10 and nvidia_acajefec3 is Windows 7. I've been following some guides around and I am always stuck at GRUB not able to detect the usual RAID content. I've tried running: sudo grub > root (hd0,0) GRUB complains it couldn't find my hard disk. So I tried: find (hd0,0) And it complains that it couldn't find anything. So I tried: find /boot/grub/stage1 It said "file not found". Here's the text from the console: ubuntu@ubuntu:~$ grub Probing devices to guess BIOS drives. This may take a long time. [ Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists the possible completions of a device/filename. ] grub> root (hd0,0) root (hd0,0) Error 21: Selected disk does not exist grub> find /boot/grub/stage1 find /boot/grub/stage1 Error 15: File not found Fortunately, I got one person suggesting that what I've been trying to do is for GRUB Legacy, not GRUB2. So I went to the suggested website, ** (http://grub.enbug.org/Grub2LiveCdInstallGuide) **try to look around, and try: ubuntu@ubuntu:~$ sudo fdisk -l Unable to seek on /dev/sda This is just the step 2 of the instruction in the http://grub.enbug.org/Grub2LiveCdInstallGuide and I cannot proceed because it cannot seek /dev/sda. However, ubuntu@ubuntu:~$ sudo dmraid -r /dev/sdb: nvidia, "nvidia_acajefec", stripe, ok, 488397166 sectors, data@ 0 /dev/sda: nvidia, "nvidia_acajefec", stripe, ok, 488397166 sectors, data@ 0 So what now? Do you have an idea for how to make fdisk see my RAID array on live cd (Ubuntu 10.10)? Honestly, I am lost, very lost in trying to restore GRUB2 on this software RAID 0 system right now.

  • Vim lint check - only show message if there's an error

    - by GorillaSandwich
    I have this line in my .vimrc, which means "when I save a .rb file, run it through ruby -c" (the ruby interpreter's error checking). autocmd BufWritePost *.rb !ruby -c <afile> When I save that file, I always see output at the bottom of the screen, so I get used to it and start ignoring it. What I want is to only see output if there are errors. I can see that when there are errors, after it says what they are, at the bottom, it says "shell returned 1." How can I modify this line so that it only shows a message if the shell returns 1? Is there a way to conditionally surpress output from a shell command run in vim?

  • Be aware of the difference between CURRENT_DATE and SYSDATE

    - by Kevin Smith
    I was running some queries in SQL Developer against the WebCenter Content (WCC) schema that included date fields such as dInDate. I was comparing the dates against CURRENT_DATE. I was not getting the expected results. I did some googlng and didn’t find a solution, but I did run across a reference to SYSDATE. I tried SYSDATE in my queries and got the expected results. I did a TO_CHAR on the two date fields and found they returned different times. CURRENT_DATE returned the time from my laptop which was  in the EDT time zone. SYSDATE returned the time from the database server which happened to be in the PDT time zone. I guess if both the database server and my laptop were in the same time zone I would not have seen any problem. Here is the query I ran to display the two fields. select to_char(current_date,'DD-MON-YY HH:MI:SS'), to_char(sysdate,'DD-MON-YY HH:MI:SS') from dual; As you can see from the screen shot from SQL Developer they definitely returned different times. I’m sure there is some command or setting you can use to prevent this problem, but for me the take away is to use SYSDATE in your queries when you want to do any date comparison.
