  • Use /etc/aliases to send to a mailing-list using sendmail

    - by Pixoo
    I'm trying to configure my Debian (6.0) server to forward emails sent to root to a mailing-list. I set the ML address in /etc/aliases this way: root: [email protected] I then called newaliases. It doesn't work but when I call mail from the command line it works :/ echo "test" | mail -s"test message" [email protected] If I set my own email address in /etc/aliases it's working too. Any idea where it could come from ? Thanks

  • Apache shuts down from time to time

    - by Dugi
    I'm having trouble with my VPS as it keeps shutting apache down at least twice a day. The server is running on CentOS 6 with the latest apache. By shutting down I mean I have to go into SSH and type in this command in order to bring it up again: /sbin/service httpd start I'm not very good with servers and my host doesn't seem to have a nice customer service. Any help would be appreciated as these unexpected downtimes really know to kill one's mood.

    - by Alexander
    Hi I want to use Yahoo's compressor for compressing js and css files. Which can be found here: http://developer.yahoo.com/yui/compressor/ My only problem is that i have never used Java before. I have no idea how to execute or use this command line. I only have experience with js, jquery and php. It simply says: Usage: java -jar yuicompressor-x.y.z.jar [options] [input file] How should I proceed?

  • How do you disable an upstart service in ubuntu 10.10?

    - by Doug
    In 10.10 upstart is being used instead of sysvinit. It's possible to remove annoying upstart services which you do not want by removing the appropriate file in /etc/init/blah.conf However, this seems a heavy handed approach. How do you correctly configure upstart to be able to selectively turn these services on and off via the command line? As a practical example, the answers listed here to turn gdm off using rcconf no longer work: How do I prevent GDM from running at boot on Ubuntu?

  • Can't boot from CD

    - by Jason Swett
    I installed Ubuntu on a PowerBook G4 and it only works about 10% of the time. For this reason I decided to re-install OS X, but my machine won't boot from CD. It also won't boot Ubuntu the vast majority of the time, so I'm kind of screwed. After a ton of tries, I finally got my machine to boot a Linux command line. Is there anything I can do at this point to make my machine more runnable, just for the sake of installing OS X?

  • Fail2ban memory usage

    - by ltsstar
    Since my server is under a sustain DNS amplification attack (DDOS), I configured fail2ban and initially my outgoing traffic dropped markedly. Anyway, after a few hours (mostly +10), fail2ban uses about 75% ram and seems to be crashed in some way, because the outgoing traffic raises imediatly after. When I searched the web for the memory problem, I found some people complaining about high fail2ban memory usages as well. But the recommended solution, to insert an ulimit command into a fail2ban config file, did not change that much for me.

  • Can I compile mutt under cygwin?

    - by openist
    I've been trying to compile mutt under cygwin for a few days. I always get the message: "configure: error: no curses library found" I have all the curses + devel stuff installed + termpcap, which I heard might be related. I've tried re-installing, i've tried specifying the location on the configure command line, but i'm not sure i'm doing it right: "--with-curses=/usr/lib/libncurses.a --with-curses=/usr/lib/libncurses.dll.a --with-curses=/usr/include/ncurses" Here's my config.log: http://floatsolutions.net/docs/config.log Any ideas?

  • How to display hidden Mac OS programs?

    - by LikeToCode
    Every time I minimize an application on my new MacBook, it minimizes, but when I switch to it, all i see is a menu on top saying that I am currently using that program, but it's still hidden. There is no menu command to "unhide" it, only to hide it. Is there a way to unhide it? Is there is a way to unhide it by default when I switch to the app?

  • Ubuntu display warning before shutdown over ssh

    - by gshankar
    Ok I admit it... I stupidly shutdown my remote server via ssh instead of restarting it like I wanted to do :( To prevent me doing a silly again, is there a way to display a warning / confirmation on a shutdown command? (like "Are you sure you want to shut down this server?" yes/no ) OR, can I not allow shutting down (but not restarting because I still might need to do that from time to time) over ssh?

  • Change the title of a terminal (Gnome)

    - by Kevin
    I would like to customize the name of the tab in Tilda (I guess that it doesn't change anything from the Gnome-terminal's behavior), but I can't find the exact sequence ... so far, I figured out that Bash does it when displaying my PS1 prompt: echo $PS1 \[\e]0;HELLO\a\]\[\033[01;32m\]\u\[\033[00m\]@\[\033[1;35m\]\h\[\033[00m\]:\[\033[01;34m\]\[\033[00m\] I guess that \[\e]0;HELLO\a\] is responsible for the title to be set to 'HELLO', but when I start echo -ne "\[\e]0;HELLO WORLD\a\]" only writes '[]' what's wrong with my command ?

  • How to avoid keyboard layout automatically changing on windows

    - by andrecarlucci
    I have two input languages in my language bar (windows xp). The problem is that windows likes changing between them without any intervention. That's really annoying! I know about the shortcuts and already turned off Word language detection, but the problem is everywhere (specially command prompt). I use both languages and I want to change between them only manually. How to turn off this automatic change?

  • Executing git post-receive hook on windows server

    - by zulkamal
    I trying to execute a post-receive hook on a windows server git(msysgit) installation - to sync the repo to codebasehq. The script does nothing more than just wget "url" but it doesn't seem to be executing. I've renamed the "post-receive.sample" to "post-receive" and installed wget to windows path which works fine via the command prompt. Is there something I'm not doing here? I would appreciate any insights on how to get this working. Thanks.

If this approach is not correct are there any other ways to automate hardware raid config ?

  • mysqldump is not dumping my data

    - by oompahloompah
    I am running mysqldump on Ubuntu Linux (10.0.4 LTS) my mySQL version info is: mysql Ver 14.14 Distrib 5.1.41, for debian-linux-gnu (i486) using readline 6.1 I used the following command: mysql -u username -p dbname dbname_backup.sql However when I opened the generated .sql file, I saw that most of the tables had only the schema dumped and in the few cases where the actual data was dumped, only 1 or two records were dumped (there are ATLEAST several tens of records in each table). Does anyone know what maybe going on?

  • md5sum or sha1sum of legitmate microsoft system files

    - by martyvis
    Is there a database or repository of the legitimate checksums for Microsoft system files? We think we have a 0day on DNS for Windows 2003 SP2 using IRC for command and control. (Latest McAfee does not see an issue). I want to compare our customer's dns.exe and associated DLLs with the real ones. (I will grab a fresh SP2 and hotfixed system to do this, but wonder how to do this in future without needed to do this.)

  • Copy an existing OS X install from another drive

    - by Kevin Burke
    I just bought a new solid state drive, and I'd like to copy all of the files and setup from my current Mac OS X hard drive onto it. What is the best way to do this? I have a 1TB external hard drive, my drive backed up on Time Machine, and Snow Leopard on a DMG, but no external mount for the SSD, and no install DVD (it's at my parents house, promise). I'm familiar with the command line and booting up Mac OS X from a hard drive.
