  • Error with procmail script to use Maildir format

    - by bradlis7
    I have this code in /etc/procmailrc: DROPPRIVS=yes DEFAULT=$HOME/Maildir/ :0 * ? /usr/bin/test -d $DEFAULT || /bin/mkdir $DEFAULT { } :0 E { # Bail out if directory could not be created EXITCODE=127 HOST=bail.out } MAILDIR=$HOME/Maildir/ But, when the directory already exists, sometimes it will send a return email with this error: 554 5.3.0 unknown mailer error 127. The email still gets delivered, mind you, but it sends back an error code to the sending user as well. I fixed this temporarily by commenting out the EXITCODE and HOST lines, but I'd like to know if there is a better solution. I found this block of code in multiple places across the net, but couldn't really find why this error was coming back to me. It seems to happen when I send an email to a local user. Sometimes the user has a .forward file to send it on to other users, sometimes not, but the result has been the same. I also tried removing DROPPRIVS, just in case it was messing up the forwarding, but it did not seem to affect it. Is the line starting with * ? /usr/bin/test a problem? The * signifies a regex, but the ? makes it return an integer value, correct? What is the integer being matched against? Or is it just comparing the integer return value? Do I need a space between the two blocks? Thanks for the help.

  • Find all duplicate files by md5 hash

    - by Jamie Curran
    I'm trying to find all duplicate files based upon md5 hash and ordered by file size. So far I have this: find . -type f -print0 | xargs -0 -I "{}" sh -c 'md5sum "{}" | cut -f1 -d " " | tr "\n" " "; du -h "{}"' | sort -h -k2 -r | uniq -w32 --all-repeated=separate The output of this is: 1832348bb0c3b0b8a637a3eaf13d9f22 4.0K ./picture.sh 1832348bb0c3b0b8a637a3eaf13d9f22 4.0K ./picture2.sh 1832348bb0c3b0b8a637a3eaf13d9f22 4.0K ./picture2.s d41d8cd98f00b204e9800998ecf8427e 0 ./test(1).log Is this the most efficient way?

  • Change XRDP keyboard layout to en-gb Ubuntu 12.04

    - by Earl Sven
    Does anybody know how to change the keyboard layout to en-gb in an XRDP session on Ubuntu 12.04? I am using mstsc.exe to connect to an XRDP server hosting an XVNC session, however I cannot work out how to apply the UK keyboard layout. A bit of googling has yeilded these instructions which allow me to change the keymap, however using the keymap file I downloaded from here I loose the ability to use the arrow keys, home/end etc. Comparing the file with the standard one there are substantially more differences than I would expect considering the similarity between the layouts. I only have RDP access to the box so i don't seem to be able to actually generate a new layout per the instructions above, maybe it's a local console thing? Also I can't change either the RDP client used or the RDP server as they are my only access to the system, I don't have local console access. I do have root priveleges on the OS however. Any thoughts? Edit: I have found http:// xrdp.sourceforge.net/documents/keymap/newkeymap.html (apologies for not typing the link properly but the antispam filter won't let me post more than 2 links) this documentation on the XRDP sourceforge page which describes keymap file format. It indicates the values in the keymap files are unicode 0x64 etc, however the files I have already on my system seem to use a different format 0:0 or 65307:27 etc, does anybody know what the difference is?

  • How to redirect logs from Cisco firewall to a specific file ?

    - by nitins
    We need to redirect the logs from our Cisco firewall(SA520-K9) to syslogd server(it's a CentOS server). The settings are done on the firewall. But the messages from firewall are going to /var/log/messages and console instead of /var/log/firewall.log which is our requirent. *.info;mail.none;authpriv.none;cron.none /var/log/messages authpriv.* /var/log/secure mail.* -/var/log/maillog cron.* /var/log/cron *.emerg * uucp,news.crit /var/log/spooler local7.* /var/log/firewall.log This is our syslog config file. Any advices ?

  • Google Play Music Not Adding MP3s On-Demand

    - by J0e3gan
    My recent attempts to add music on-demand to Google Play Music have yielded nothing - no "Processing music..." or "Added __ of __" messages, just nothing. Previously I could add music on-demand; and nothing has changed on the machine from which I successfully added music previously, from which I have tried to add music on-demand recently. What could be hampering my ability to add music on-demand? WHAT I'VE TRIED: Right after I started using GPM, I briefly found that I could not add music (on-demand), but the problem went away after a logout/login. This time a logout/login has not helped. Dragging & dropping or browsing to folders or files to add has made no difference either. Nor has waiting ridiculously long for GPM to show signs of life after adding music on-demand seemed to work. Digging deeper, I read a related Google Play Help article and followed its suggestions... ran the Google Play Music Manager troubleshooter = no errors or warnings double checked my available storage = 8 GB free double checked supported file types = MP3 is still supported (of course) ..., but the problem remains. UPDATE: I found that if I configure GPM to automatically upload music added to specific folders, it strangely does add automatically what it will not add on-demand.

  • NFS inherit permissions from shared directory - Mac OS client

    - by devius
    Short question: Is there a way to have files on a NFS share on the client inherit the permissions of the shared directory? Scenario: Ubuntu 12.04 server Mac 10.7.4 client shared directory has 775 permissions created files on client have 644 permissions I tried setting ACLs with the setfacl command, as explained here, and it appears they are set on the server. getfacl returns this: # file: Documents/ # owner: someguy # group: somegroup # flags: -s- user::rwx group::rwx other::r-x default:user::rwx default:group::rwx default:group:somegroup:rwx default:mask::rwx default:other::r-x However, when I create a new file on the Mac OS client it still has 644 permissions and not the 664 I would expect. Files created on the server have the expected permissions. Files created with another Ubuntu client also have the expected permissions.

  • Good Free Ubuntu Server VMWare Image Needed

    - by Yaakov Ellis
    Can anyone recommend a good, free Ubuntu Server VMWare Image (or Virtual Appliance, as they call them)? I have looked on the VMWare VAM and there are literally hundreds to choose from. I am looking for something that can with very minimal effort serve as a development platform for LAMP applications (so it should have all of those installed, plus things like PhpMyAdmin). Bonus points if there is some way to create new Virtual Hosts (for developing and testing new sites) on Apache without having to go digging around conf files and guessing on the sytax.

  • x11vnc is slow, but using only 10% of available bandwidth

    - by mmm
    I am using x11vnc over 15Mbit/s network with 20ms latency. When the screen is changing a lot x11vnc is slow - for example when I switch a tab in a browser, it takes almost two seconds until the view is fully redrawn. The strange thing is that max connection speed of x11vnc is even during slow redrawing only about 10% of the available bandwidth. Why is x11vnc not using available bandwidth to speed the redrawing up? For example scp is using 100% of available bandwidth without problems. How can I identify what is the bottleneck for x11vnc on my system? So far I think: 10% network usage = network is not a bottleneck fb read rate: 601 MB/sec = reading fb is not a bottleneck Any ideas how can I further profile x11vnc and find out what is causing a slowdown? For example is there any switch for x11vnc to show how much data it is handling and how long it takes to grab a screen, process and compress it and send it over the network?

  • "postgres blocked for more than 120 seconds" - is my db still consistent?

    - by nn4l
    I am using an iscsi volume on an Open-E storage system for several virtual machines running on a XenServer host. Occasionally, when there is a very high disk I/O load on the virtual machines (and therefore also on the storage system), I got this error message on the vm consoles: [2594520.161701] INFO: task kjournald:117 blocked for more than 120 seconds. [2594520.161787] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. [2594520.162194] INFO: task flush-202:0:229 blocked for more than 120 seconds. [2594520.162274] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. [2594520.162801] INFO: task postgres:1567 blocked for more than 120 seconds. [2594520.162882] "echo 0 > /proc/sys/kernel/hung_task_timeout_secs" disables this message. I understand this error message is caused by the kernel to inform that these processes haven't been run for 120 seconds, most likely because a disk access to the storage system has not yet been processed. But what is the effect on the processes. For example, will the postgres process eventually write its data when the storage system is idle again after a few minutes, so that all data is still consistent? Or will it abort the write, leaving some tables in an inconsistent state? I certainly expect that the former should be the case - if the disk access is slow, postgres (or any other affected process) should just wait as long as it takes. I can live with the application hanging for a few minutes. But if there is a chance for data corruption then any of these errors is really bad news. Please advise what to do here.

  • Chmod 644 on /etc/ any way to fix?

    - by DazSlayer
    I tried to tab complete something and I guess it wasnt there. I know you are not supposed to set the permissions to /etc/ like that, but my permissions seem to be all messed up. whoami prints out cannot find name for user ID 1002 and I cannot cd into /etc/ anymore. passwd and shadow use 640 and 644 so I am not sure why this is a problem. Regardless, is there any way to fix this? The command run was sudo chmod 644 /etc/ I have no name!@vpn-server:/$ whoami whoami: cannot find name for user ID 1002 I have no name!@vpn-server:/$ cd etc bash: cd: etc: Permission denied I have no name!@vpn-server:/$ ls -al etc d????????? ? ? ? ? ? . d????????? ? ? ? ? ? .. d????????? ? ? ? ? ? acpi -????????? ? ? ? ? ? adduser.conf I have no name!@vpn-server:/$ sudo su sudo: can't open /etc/sudoers: Permission denied

  • time sync with ntpd

    - by guthrie
    I run Debian on several systems, and their times do not seem to stay in sync. I can run ntpdate manually, but I thought that I should have an ntpd running that would automate that. I did check with apt and apt-cache but don't find any ntpd (or associated ntpq), not any such names in my system (locate...), but ntp-doc does still describe them. Looking around I see that there is an ntpdate-debian command, and it uses /etc/default/ntpdate for servers (instead of the standard /etc/ntp.conf), but even thought that file is there and has "yes" indicated to use ntp.conf, it fails with "no servers can be used", although ntpdate works fine. Is this just a layer over ntpdate, any reason to use it instead? So, why are they missing, do I need them, how do I automate time updates? Associated, two of my machines are virtualized on a MSoft VM, how is it that their clocks drift, and both to different values? (The underlying Windows machine clock seems stable). I see a few old notes about time & ntp problems on VMware, didn't find anything either current or relating to MSoft VMs. Anything I did see says just to use ntpd, but as above, ...?!

  • Nginx error page with JSON response

    - by Waseem
    I'm trying to serve a maintenance page to clients making request to my application when it is under maintenance. Following is my nginx configuration for that purpose. server { recursive_error_pages on; listen 80; ... if (-f $document_root/maintenance.html) { return 503; } error_page 404 /404.html; error_page 500 502 504 /500.html; error_page 503 @503; location = /404.html { root $document_root; } location = /500.html { root $document_root; } location @503 { error_page 405 =/maintenance.html; if (-f $request_filename) { break; } rewrite ^(.*)$ /maintenance.html break; } } Lets say I have enabled maintenance of my site by creating a $document_root/maintenance.html.

Background: I have a directory containing a lot of different versions of a library and I'd like to do some cleanup work and delete the versions which weren't used in any projects. Thanks, Mathias

  • Read only bind-mount?

    - by depesz
    I use mount -o bind to mount directories inside chroots, which works really well. The problem is that I'd like some of these bind-mounted directories to be read only in chroot. Is it possible? If not - any other way to achieve it? I was thinking about using NFS for localhost mounts, but it looks like overkill.

  • Booting Fedora guest VBox on /dev/mapper/vg0-fc17-root

Or is there a better way? (Maybe grub on vg0-fc17-boot?)

  • What else is needed to get iptables to log into this file I created?

    - by anthony01
    I want to create the logging of iptables DROP's and intrusion attemps. First, I put --log-prefix "iptables: " at the end of every iptables rules in my iptables rules file. But this doesn't work, as it says there is a syntax error. So where should I put that command? (I would want to have it included in the saved rules file) Secondly, I created a file iptables.conf within /etc/rsyslog.d/, and I put the following inside of it: :msg, startswith, "iptables: " -/var/log/iptables.log & ~ I assume that at this stage, I'm supposed to restart the rsyslog daemon. What else is needed to do what I'm attempting? Thanks a lot

  • Moving from Ubuntu desktop to Ubuntu Server via SSH

    - by Daniel Elessedil Kjeserud
    So a little while ago I installed regular Ubuntu for a home server, but that gave me a lot of extra packages. What I should have done was to install Ubuntu Server, since I don't even own a screen to connect to it. Does anybody know of a way to convert my Ubuntu machine to a Ubuntu Server machine in one big swoop? It has to be done over SSH, since I don't have a screen to connect to it, like I said. It's currently running 9.10, about to be upgraded to 10.4.

  • Where to set catch-all address in Postfix (virtual mailboxes in affect)

    - by Cem
    I successfully configured Postfix to deliver messages to virtual mailboxes. I can set aliases and pipes inside /etc/postfix/virtual and mailboxes inside /etc/postfix/virtual_mailbox files. However, whenever I set a catch-all domain and point to a remote email address, it overrides all other virtual mailboxes and virtual aliases set in postfix. How can I set a catch-all forwarding to the remote email address when virtual mailbox is enabled? I set catch-all like this: @mydomain.com [email protected] Thanks for your help!

  • How can I sort out Xephyr's keyboard mapping?

    - by qedi
    When I start up Xephyr inside of X, my keyboard map becomes wonky mostly just for non-printing characters. I can't use arrow keys. According to xev, The down arrow gets mapped to Super_R. The up arrow is Print Screen. PgDown is mapped to "Menu". My keyboard works fine in the original X display (:0), but in the Xephyr subdisplay (:1), nothing else quite works right. I don't have any funky xmodmap things going on in my main X display that I'm aware of. All I really do is setxkbmap -option ctrl:swapcaps.
