If I do setenv DISPLAY other_machine:0 and launch a gui application I can send this application to my other_machine Is there any mean (utility or whatever) to send an OPEN application to another machine (by its pid eventually) So if I have an nedit open, and its pid is 13245, I could do something like send_to_display pid=13245 machine=other_machine:0

View 1 Replies View RelatedI was wondering how to change the xterm font size and may be the font itself. Also we go to tty1 when we press Ctrl+Alt+f1 , f3 and so on. Is there any way I can change that too and maybe change the colour of the font and the size of it. I did change the resolution once in ubuntu with startup manager. I'm using fedora 14.

I want to change parameters of a RED queue during the simulation but it seems that some parameters can be modified only before starting the simulation, not dynamically, while the simulation is in progress.

I am running hummingbird exceed on Workstation with an ip address of a.b.c.d, and connecting to a sun machine with IP address x.y.z.w running Solaris with XDMCP. From the sun machine, we commonly telnet to other sun and linux machines and run X applications.
We have just installed ubuntu 10.04, and I can telnet into that machine no problem.
However, running xterm on the ubuntu machine fails:
xterm Xt error: cannot open display a.b.c.d:0.0
When I run xterm from the command line, there seems to be some errors:

I'm having a problem with vim and xterm. When I open a file and press any key, the colour scheme changes slightly. This doesn't happen if I run a 256-colour xterm (export TERM='xterm-256color') but if TERM is set to 'xterm' (the default) I see the colour change. Setting TERM='xterm-256color' in my ~/.bashrc is a "solution", but I'd rather not have to do that since it's never been necessary in the past (e.g., on 13.1) and I don't use any 256-color schemes for vim (usually just the default or possibly "delek"). It doesn't happen with rxvt or with Xfce's terminal. I've tried compiling some other versions of xterm but they either exhibit the same behaviour or don't build. I have tried running without any ~/.vimrc file just to be sure it wasn't one of my settings and I've also tried the sample file at /usr/share/vim/vimrc; the effect is the same.

View 1 Replies View RelatedI'm using OpenSUSE as a guest OS in VMware. Display settings are 1400x1050@60Hz but I want to change them for 1440x900. Using root account I go to Configure Desktop -> Display -> 1440x900. The first problem is that I can't choose 60Hz, only "Auto" or "0.0". I click Apply and the resolution changes, but if I reboot the computer or just logoff... resolution goes back to 1400x1050. My card and monitor properties: [URL]. Another strange thing is that if I click Ok on the Card and Monitor properties (changing from one resolution to another), I can choose to "Test" it, and xfine2 appears but... it ALWAYS says "1400x1050".

I know this is somewhat lame, but I remember back in college the MOTD on some of the systems was a random quote. I always wanted to do that. It seemed really trivial, but still neat and clever.
I searched a bit and don't see anything built-in for CentOS, so I was considering writing a Perl script to parse the RSS feed from a quotes site, then update /etc/motd with a random quote from the feed. This would nearly guarantee I could have this on any distro with identical results. Does anyone know of anything that already exists? Is anyone interested in using a script that I write to have the MOTD updated with random quotes themselves, or am I the only one? I'm perfectly willing to share the result when I'm finished.
I'm looking for a way to dynamically modify a fied in the SQL file.
Example,
INSERT INTO `TABLE` VALUES(1AADFDF,DFF33D,10023,SOMEDATA, SOMEDATA);
INSERT INTO `TABLE` VALUES(1AADFDF,DFF33D,10098,SOMEDATA, SOMEDATA);
[code]....
The third field in this SQL file is what needs to change to n+1
"10023" needs to change to "1"
"10098" needs to change to "2"
"10123" needs to change to "3"
"10983" needs to change to "4"
etc...
I tried with awk and sed, but since both require the usage of ' (single quote), my variable fails to get updated. I know i can use cut and recreate the sql statememnt, but i believe there should be easier way using sed or awk. Would anyone know of any creative way to get this to work in one-liner? This needs to be a part of the script preferable without making call to external file.
Libraries have always been ambiguous to me. I would love to have a clear understanding of them. Here's what I know so far... Ok I know that libraries are a bunch of functions and definitions in C that binaries use. I also understand that static libraries are used by the binaries in /sbin:/usr/sbin:/usr/local/sbin and dynamically linked libraries are used by the binaries in /bin:/usr/bin:/usr/local/bin So why have statically linked and dynamically linked libraries? I know that dynamically linked libraries are used to save space. Otherwise each binary would need its own private copy of a library. So dynamically libraries are used to save space.
1. Where are the static libraries and the dynamically linked libraries located in the file structure?
2. Where does ldconfig fit into all of this?
3. Would a rootkit affect both statically and dynamically linked libraries? I would think yes unless the libraries only have read permissions.
4. If the above is true, is there any reason for your libraries to have write permission other than when you want to edit them?
