I preparation for this.I have bought a new motherboard, AMD Phenom X4 3.6, and 2 more 2TB 7200rpm (Currently, I have a 2TB 7200rpm not used much)Been digging around this forum for posts with raid setup but still not sure how to seamlessly moving the some 10Gig of data from my current running prod environment once I have RAID5 installed on this new machine via the LIVE Ubuntu Server CD.
Running Red Hat (not sure of the build atm) and I need to be able to put all of the IP blocking in a separate file. It will eventually be uploaded to a large number of hosting accounts, and modified from time to time...so it isn't feasible to modify that many httpd.conf files each time we need to add an IP to be blocked. In httpd.conf I can add the "Deny from" line to the following directive and blocks it just fine:
Code:
<Directory "/var/www/html">
#
# Possible values for the Options directive are "None", "All",
# or any combination of:
# Indexes Includes FollowSymLinks SymLinksifOwnerMatch ExecCGI MultiViews
[code]....
There is an include to pick up all *conf files in ../conf.d, and everything else in there is working just fine. I created a file called robots.conf; it currently has a set of mod_rewrite rules which work. So I added this to that file:
Code:
<Directory "/var/www/html">
Order allow,deny
Allow from all
Deny from 123.456.789.098
</Directory>
It is not blocking access from the IP with it in there.I've done all of the usual things; restarted Apache, cleared browser cache etc. I can also block it using that same directive in a local .htaccess.
I am having problem with the root disk / fill up. So now that i have the disk information provided from SAN team Id 0:3, how would i do to add this device to / to increase space on Redhat Enterprise server 4?

I have recently converted to Linux after taking a system architecture course which exposed me to OpenSuse. I have my main desktop up and running with OpenSuse and now I'm determined to dust off my old pc's at home and get them up and running again. I might need some guidance or tips along the way so thats why I'm here.I have four old pc's running on Windows Home XP with 512mb or less of ram. I am planning on upgrading them to at least 1 or 2gb of ram to get as much as I can out of OpenSuse. Should I install the ram before I before or after switching them all to OpenSuse? What network adapter do you guys recommend?
View 9 Replies View RelatedHere's a trick I'd like to be able to do. You know how on Windows systems, you can copy the contents of the install disk to a folder, then point the system at it and when it would normally ask you to insert your Windows CD, it just reads that folder?
That's pretty much what I want to do. I want to put the contents of the Ubuntu CD-ROM on the HDD such that if I ever need to refer to the CD, it thinks it's already inserted and just reads from there.
This may sound like an odd request, but I'm asking because my Linux server is an old cheapo computer that doesn't have an internal CD-ROM drive. I have one that I can hook up, but it's a pain in the butt to open the case, set the jumpers, attach the drive, reboot, etc.
This would be a lot simpler for me. This way, if I ever need to access something that was on the Ubuntu Server CD-ROM, I want to be able to just get it from right on the hard disk. (I've got the drive space, after all.)
Whenever I put a few files into a blank CD or DVD, wether it's pictures, music, documents, whatever, and then I use it another day and try to put a few more files into it, Ubuntu won't let me. I used to be able to continue adding files to my CDs in XP, so I'm not sure if there's any way to do that with Ubuntu? It just shows the DVD as (for example) 1.4 GB used, 0 GB free.

The HDD's will sleep with out issue. Ive looked around my log files and cant seem to find anything to do with hdparm, or the HDD's sleeping. Have I make a mistake in the .conf file? Is there some place hdparm logs, or if I can activate some sort of verbose mode? Or does hdparm need to be activated on boot?

So I copied grub files into boot section, but now I need to "root and setup" it - and that's what I can't do, because I don't use Grub1 normally, since I am on Ubuntu which uses Grub2.
(I decided to use Grub1 instead of Grub2 because Sabayon could have some special params, and I am not that much experienced to copy them in new format to grub2 configuration file). So my question is - is there a way to copy grub1 to MBR without having it installed? (using some utility or something like that).
I'm using Debian Jessie (with YunoHost v2). Recently the PC on which I had installed it stopped working (power supply dead) so I put the hard disk in another PC. The system seems to start up correctly but I cannot see the ethernet and wlan interfaces in ifconfig (only lo).
The old PC was an Asus EeePC 1001 HA. The new one is an Acer 5920G. I ran Linux (Mandriva) on it in the past with no difficulty.
lspci shows this:

I switched to fedora to learn. I also purchased several vps (virtual private servers) so I could hack away and not destroy my pc. well I would like to do the following...let me call one server A and the other server B
Put to terminals on my top panel. when I click on A I will automatically via ssh be taken to the server A online and when I click on B (the second xterm icon) I would like to be taken to vps B. Ideally I would also like to bypass my password and just go in a root to both as again these are just things I got to learn on.. I don't know where to start but it sure seems like something that would be possible. Of course I don't care if I am clicking on the terminal icon or a program that just launches the appropriate terminal..
I am shortly getting a new computer, It will arrive with Windows 7 on one disk and will have a second disk, on which I will install Fedora. In the past, when I've set up a dual boot system, I always used the standard configuration with the first part of grub put in the MBR. But this time I would like to put grub entirely in the Linux disk and then use Windows 7's boot loader to boot. I set up another computer that way where the disk originally came with Vista. But in that case, I set it up the standard way and then changed it afterwards to use the Vista boot loader.
This time, I want to set it up when installing Linux so grub is entirely on the second Linux disk. So until I manage to figure out how to get the Windows boot loader to do the job, I need a separate way to boot Linux, say from a CD with grub on it. But that CD should have the appropriate grub configuration on it. The easiest way I know to create such a CD is from Fedora, but there is the problem that I first need to get into Fedora to do it. I can think of several ways to approach that problem, i.e., using the installation disc in rescue mode or using some raw grub booter created from my old system. But I would like to keep things as simple and direct as possible, since otherwise I'm sure there will be false starts and a lot of fiddling.
So could someone direct me to some simple instructions to do what I want as quickly as possible. In particular, are there any options to do it in the installation process?
I have a Tomato router and it has the capability to have its logs go to a external server. syslog is the obvious choice for this. So I enabled remote logging on my linux server's syslogd (syslogd -r) and I can see all of the logs in /var/log/syslog. What I want to do is take everything that comes from the IP of my router (10.0.0.1) and divert it to its own file like /var/log/tomato to avoid polluting my syslog with external logs.
I can't find any examples of someone doing this. My only solution is to get a script together that strips out any line in /var/log/syslog with 10.0.0.1 in it and puts the line into /var/log/tomato and have the script run as a cron job, but that seems unnecessarily messy.
Unless someone knows that there is a solution, I'm 95% sure that syslog doesn't support this after reading more in-depth of the man page. So I need to migrate to syslog-ng or make a crazy script that runs with cron.

I want to totally delete it, and put JUST xubuntu on these computers. I know nothing about Mac, except I got these, and they have pretty colored housings. I've tried using the 'c' and 'apple+c' commands to get this to boot from the xubuntu cd, but it doesn't have any effect. The thing just continues to load OS9.
I'm seeing from all these threads that everyone is pretty much dual booting, or multi-partitioning the hdd. I do NOT want to do this. Is it possible to format the drive completely, so that it is utterly blank, and then install xubuntu? Am I going to have to get new hdd's for them? They all work just fine, no problems except the software is so old that you can't do anything with it but use post it notes.
OK I have a simple script that does:
Code:

View 8 Replies View RelatedYears ago on AIX I used to create a file of key strokes, including function keys (mainly F3 and F12) into a file, and used that file as input to an INFORMIX program, to automated tasks, something like this:
fglgo myprogram.fgo <keystrokefile.txt
Now, I'm using Aubit language on GNU/Linux, and I'd like to do the same kind of thing, but I can't recall how I worked out the chars for the function keys, I'm using a different emulation (xterm), and I can't work out what characters to put in the key stroke file. My $TERM variable contains "xterm". If I type "infocmp", I get this:
Code:
# Reconstructed via infocmp from file: /usr/share/terminfo/x/xterm
xterm|xterm terminal emulator (X Window System),
am, bce, km, mc5i, mir, msgr, npc, xenl,
colors#8, cols#80, it#8, lines#24, pairs#64,
acsc=``aaffggiijjkkllmmnnooppqqrrssttuuvvwwxxyyzz{{||}}~~,
[Code]....
1. Is the above infocmp output the place I should get the information I need?
2. What chars do I need to put into my file to simulate me pressing F3 and F12?
3. Is there a way for me to put such chars in a file by just pressing those function keys (I tried a here document, but that doesn't work (it's as if the function keys are not even pressed)).
I have a problem with my script. The problem is the system keeps rebooting after I put the directory file in .bashrc. The intentional for putting the file in .bashrc is to run the script automatically after login as root, I don know why is this happen. It was working fine for the first time without putting the file in bashrc. I could break the loop after hitting the "ESC" key. would it be the script problems?
Here is my script
count=20
while [ $count -gt 0 ];do
sleep 1
echo Press ESC to break the operation
((count=count-1))
