I wrote a Perl script which will serve as a daemon, so I'd like to let the OS (in my case, Ubuntu Linux) automatically run my Perl script after it has booted up.
How can I do that?
Can a Mac Mini, Server edition, be booted off either of its two disks?
I'm interested in having one disk with OSX Server on it, and the other a dual boot Linux/Windows, to get around OSX's fussiness about boot loaders.

I need to check RAM on a server located in a data center several hundred miles away. So, I can't just walk over and boot to CD to run memtest86. Is it safe to run this while booted into the OS? Does anyone know of a knoppix pxe boot image? I can network boot to something...I just don't know what to network boot to.

View 7 Replies View RelatedI am in the process of creating a kickstart configuration file for some RedHat 5.5 and Centos 5.5 servers (Production and test respectively).I have googled about a bit but I cannot find a good list of the bare minimum packages required for a command-line system.If anyone knows how I can trim this list down anymore it would be much appreciated. The aim of this kickstart.cfg is to get the system booted to a bare minimum required to install Chef (Server management software). Chef will then setup Apache, Ruby on rails environment etc.
All this server will need to do is, from a static IP, Host a Ruby on rails app, send emails, send data to a server on the web, accept ssh and occasionally and connect to a SMB/CIFS share This list was taken from the anaconda-ks.cfg file after a RedHat install of what I thought was a pretty minimal system onto a VM but I noticed that cups, the avahi daemonsand gam_server are installed and running which I do not believe are needed for a pure web server.I know that these types of questions are hard to answer without a complete knowledge of the operating environment and what "minimum" is in this case ("@core only? but I wanted yum damnit!")

View 4 Replies View RelatedI just booted ubuntu from a disk that I burned to try and salvage some files off a hard drive with a failed boot sector (maybe. not sure what the problem is,). Anyway, I can see the files, and I have a large portable hard drive that I can use (a MyPassport 320gig, if I recall correctly). I'm having trouble accessing the drive, and I think it might be because there's something popping up in the task bar that I can't see. Unfortunately, I can't see the task bar! My screen's resolution is off, and I'm having trouble adjusting it. I browsed the various settings and I couldn't figure out any way to change it.
Is there anything I can do? EDIT: Oops! I didn't look into the Monitors options... how embarrassing.
EDIT2: Okay, looks like I can mess about with the resolutions, but all of them still deny me access to the full screen - still can't see the task bar.
Since 10.10 is not out yet, I think I'm going to try Mint. (or possibly Lubuntu - I have both ISOs copied to CD already)
Question is: Is it possible to install the new OS on the partition that now contains Ubuntu, without disturbing my Windows Vista partition? (I just need Vista for occasional use of MagicJack- otherwise I'd gladly just wipe the whole disk)
Can I just boot my Ubuntu live CD and run Disk Utility and delete the Ubuntu partition? (I prefer to use GUI rather than CLI).

View 1 Replies View RelatedI have been dual booting my XP and Ubuntu for a while now. However, my pc monitor does not turn on until I am booted into windows/linux. This means I have to 'guess' to a certain extent which OS to select on boot (using GRUB). I expect I will have to change a setting in the BIOS but I am not too sure what to look out for.
After turning on my pc I have to restart it for it too do anything, it appears to just hang!However as I cannot see what is happening due to the monitor problem I am completely in the dark as to why it would do this/what is going on! I have XP installed at the front of my hard drive and Ubuntu at the back. It worked ok the first time I tried it after install (still had the monitor problem but was able to guess) then after that this random problem!
I have a Fedora 12 system. Having some boot problems here and I booted up my Fedora 12 live CD to troubleshoot it. My boot problem is I get to this message: Registering binary handler for windows applications: Then the screen flashes a few times and enternal hang begins. I installed wine before the reboot. I cannot figure out where my HD (which is sata btw) is after liveCD bootup. I figured I could turn wine off some how. Is it in rc.d or init.d? Anyhow here is my mount info from terminal.

View 14 Replies View RelatedI have a small problem with Perl and Apache.
If I use "#!/usr/bin/perl" in the beginning of a perl script the script won't work if the script is at all complicated. Simple scripts like "Hello World" works.
But if I use "#!/usr/bin/perl -w" in the beginning all scripts work?
If I don't use the -w this is whats in the logs:
(2)No such file or directory: exec of '/home/test.net/html/cgi-bin/uh/meny.pl' failed
Premature end of script headers: meny.pl
When I use the -w in the script the error-log shows me this.
meny.pl: Name "main::http_path_cgi" used only once: possible typo at /home/test.net/html/cgi-bin/uh/meny.pl line 24.

View 3 Replies View RelatedI recently reinstalled the B module for perl. Now I found out it didn't just do that, it installed a whole new copy of perl into /usr/local/bin/perl. When I type 'which perl' at the terminal, it says '/usr/local/bin/perl' instead of '/usr/bin/perl'. Normally, this wouldn't bother me. But I installed the one in local/bin without threading support. The one that comes with the system already is build with threading support, which is why I want to switch back to the system perl, and possibly remove the one in /usr/local/bin.
So how do I change it so that the result of 'which perl' returns as '/usr/bin/perl'? And what do I have to do to remove /usr/local/bin/perl?
The reason I need threading support is because I'm designing a file copier that copies several chunks of a file simultaneously to speed up the copying process. Guaranteed a useful script if it works.
