It's a nuisance having to change folders and I can't configure wastebin to empty on exit.And I can't get kmail to import from evolution. Do I have to go to the evolution storage and do it manually, and if so, how do I do that?

Programming :: Launching Interactive Gnome-terminal With A Command (and Not Exiting)

Oct 13, 2010

I want to have a script (tcsh/bash/python) that launches a bunch of gnome-terminals (or 1 with multiple tabs). And I want it to execute a command, but keep the shell interactive. Currently, if you type gnome-terminal then it launches a new interactive shell, but if you give it the execute flag, then it executes the command and quits (or stays open, but non-interactive depending on the users gnome-terminal settings).

I have this command which I want to run automatically before I start working. What the command does is dynamic and different for each shell. It takes arguments. So it's not something I can take care of in a .cshrc type file.

Security :: When To Give Write Access To Folders On A Web Server

Feb 3, 2011

on the following link [URL] section 2 says

Quote:

The following directories need to be readable, writeable and executable for everyone:

* dokeos/main/inc/conf/
* dokeos/main/upload/users/
* dokeos/main/default_course_document/
* dokeos/archive/

[Code].....

I am not at all convinced by the idea of giving permissions to read,write and execute as these Learning Management Systems say. Let me know what you people have to say? What is the best practise in such situations? I have to get all these LMS run on same web server.

Ubuntu :: Give A User Sudo Privilege From Command Line?

Mar 14, 2011

I adjusted some settings in the desktop settings folder in KDE. I had only one user account on the machine. Next time I rebooted I could not log into KDE (it kept bombing out). I had to log into the console. Finally I managed to create a new account with useradd but this user cannot sudo

My problem is that my home directory is encrypted, so I need a new user with sudo privileges to delete all the kde files and folders in my original users home directory so that I can start with a new KDE setup (which won�t be a bad thing since I tinkered a lot).

How can I add sudo privileges to the new account (I presume I can do it by logging in with my sudo account in a terminal login?

Programming :: Perl - Directories Given To Opendir Via Foreach Give "No Such File Or Directory" Error

Feb 19, 2009

I'm writing a perl script to remove a test database and part of that is of course getting rid of all files. So I wrote this to do the job:

Code:

This always results in an "Could not open /u00/app/oracle/product/10.2.0/rdbms/dbs for reading: No such file or directory" (that directory is the one ending with the $spfile_dir variable) message, although that directory exists and the executing user has writing rights on it.

The same behaviour if I create the directory array like this:

Code:

The problem does not occur when one of the directories is the only element in the array though. Of course I could copy and paste that part of the script for the second directory, but I don't like that workaround.

Programming :: Write A Small Perl Script To Collect Some Info From Mysql?

Oct 10, 2010

am running Centos 5.4 and would like to write a small perl script to collect some info from mysql.

so I went
yum install perl-DBI
yum install perl-DBD-mysql

then

nano perl.pl
---
#!/bin/perl
use Mysql;

[Code].....

Why can't perl find Mysql.pm? I guess because it doesn't exist as I ran find / -name Mysql.pm, and also could not find it.

shouldn't that file have been created and thus exist after I install perl-DBD-mysql?

Programming :: Effect Of Using Eval To Execute A Command As Opposed To Writing It On The Command-line?

Jun 18, 2010

Code: cmd='date | wc'

$cmd If this script is executed, an error is generated. The reason written was that "The execution fails because the pipe is not expanded and is passed to date as an argument".What is meant by expansion of pipe. When we execute date | wc on the command line, it goes fine.then | is not treated as an argument. Why?

Ubuntu Servers :: Restrict User Session Numbers And Allow Resuming Previous User Session?

Jun 30, 2010

I am currently in a project to set up an LTSP server with 10 thin clients. I am using Ubuntu 9.10 (Karmic).

Installing server and booting clients are working fine. Now, according to the need, I have to restrict user session numbers and allow resuming previous user session.

I have achieved to do the first one, but still could not able to setup the second one. As per requirement, if some thin can have power failure, the same session should be restored back. I am confused here, if I need to focus on saving xsessions or saving gnome sessions. I am looking for a concrete solution as I am running out of time.

General :: Interactive Ssh Session Through Gateway Machine

Sep 6, 2010

Possible Duplicate:Forward SSH traffic through a middle machine.I am looking to get an interactive ssh session on a remote machine, but must login via a gateway.For example, right now I do the following:

@local % ssh <user>@<gateway>
@gateway % ssh <user>@<remote>

Is it possible to achieve the same thing in a single command from my local machine? I have tried:

@local % ssh <user>@<gateway> 'ssh <user>@<remote>`

From the output i am indeed able to login, but do not get an interactive session. I took inspiration for this attempt from using ssh to run a command remotely.
