Programming :: Write A Script For Work For Provisioning Servers?
May 20, 2010
trying to write a script for work for provisioning servers. It has a few questions and what not. What is the network IP and another is What is the block /29, /28 etc. If they provide the network and the block you can figure out the gateway, and usable IPs Is there a way to have /bin/sh configure the IPs with just that information? So if they provide 127.0.0.1/29 it will calculate 127.0.0.1 is the network 127.0.0.2 is the gateway and 127.0.0.3-127.0.0.7 are usable. However, it can't use the ipcfg-eth0-range0 method because Plesk doesn't like it.

I'm at ES5. Anyone have a method for roll out or backing a single RPM or set of RPMs. In other words, I install the security errata (several packages) and it breaks something. I need to back it out, and restore the original. Also, anyone have experience using Red Hat provisioning for patch management?

8.04 64bit LTS no gui loaded Only the root user can write to /tmp. I tried to create a cron job for a user and received an error
Code:
crontab -e
no crontab file for ed - using an empty one
/tmp/crontab.SCQ30O: Permission denied
Creation of temporary crontab file failed - aborting
Then I tried a simple touch /tmp/test1 and it failed with a 'touch: cannot touch `/tmp/test1': Permission denied I tried the Windows fix and rebooted, no change. Only root can write to tmp. This may sound lame but... using ls /tmp show reversed video (highlighted blue on green) on the servers the the users have access to, just plain blue on the 'broke' one. I did a sudo chmod a+w /tmp but do not know if that was a smart thing to do or not...

I'm setting up my fedora 10 server. I am currently working on samba. I have added users and created their home directories with their own html directories. I have changed their html directories to 777. However, it appears to be read-only since I cannot create files or folders within it. Can anyone please give me some ideas as to what may be causing this? Probably some extra configurations I may have overlooked? Any help would be kindly appreciated. I also created a general wshare (writable share) directory for all users within home directory but I am encountering the same problem and cannot write to it.

This is (I suspect) a Mac OS issue but they've given no help (or replies!) on Mac forums so I'll ask here.I've just got a Mac and I can connect to shares on my Ubuntu (10.04) server, read files and create directories but I cannot write. I get this error:"The operation cannot be completed because you do not have sufficient privileges for some of the items."I can connect from the command line with smbclinet and write fine. I have tried several different users on both the Mac (cannot write) and Ubuntu clients (can write).Is this something to do with the ._filename files that finder creates? Or is there something wrong with the way I've set up my server? This is the first time I've used it with a Mac client.

From a Win 7 client, I can copy/create/delete any files on any share on the Ubuntu Samba server so long that is part of my nix file system which is all ext4.This box also has and NTFS partition on it primarily for storage. I can copy/create/delete anything on this partition form the same Win 7 client with the exception of Quickbook save files.I have scoured the web looking for anything close to this but have yet to find anything that looks similar. Not lloking for a direct answer but if there is anyone else that has issues copying specific types of files to a Samba NTFS partition.

I just started messing around in Linux programming, and I wanted to create a simple test program to open a file, read to it, and write to it. I can open and read it, but write always gives errno = EBADF. I've messed with file creation permissions and I can figure out why write() thinks it's a bad file descriptor but not read().Here is my code:
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>

I need to write a GUI for the web to gather the following info:
Username
Password
SomePlainText
Path1
PathN
Of course, I then need an 'submit' button. I then want to have the user upload all paths supplied from their machine to my server. I hope to work with this data as arguments for a bash script. Also, I need to work with all possible client OSes consistently. What language should be used?

I've been working at learning how to write makefiles and I'm a bit stuck.
I've got a fairly simple project that will eventually be a framework for TCP/IP Communications in evolutionary algorithms that I've been using Eclipse to develop.
For personal development I want to learn how to write makefiles by hand but have gotten kind of stuck
Here is the makefile as it stands now:
Code:
Port and Mailbox are a virtual class and a template class respectively.
I get these errors when I run make:
Code:
So for some reason every single function in the Connection class has been defined multiple times. I assume because it's included as a dependency for multiple targets, but I've seen this in numerous examples that apparently work.
Everything in libpthread is undefined because I'm not linking in the library. I've tried adding the library options to the LDFLAGS variable but that doesn't seem to work either.

I am trying to write a gui app with python2.6.4 and wx on win XP. I am attempting to resize an image with Imagemagick from within the program using os.popen and os.system in a thread.
Code:
os.popen("mogrify -resize " + str(x) + "x" + str(y) + "!" + " images/static/" + my_ref + ".gif")
orCode:
os.system("mogrify -resize " + str(x) + "x" + str(y) + "!" + " images/static/" + my_ref + ".gif")
they both work as far as resizing the image but when os.system is used a command shell opens during the mogrify and when os.popen is used the command shell does not show but the rest of the program freezes until mogrify is done.
I would prefer that the program did not freeze during this process and the command shell did not show.I have tried using wx to scale the image but the scaled image looks crappy.anyway is there a way to use os.system and not have the shell show?

I'm trying to write a toy linux shell. For starters this is what I'm trying to do:
1. Start a new process with fork.
2. Execute a program in the new process with execl().
3. Redirect the output from the new process from STDOUT to another file descriptor, using dup2(2).
4. In the parent process, read the output from the child process and write it to the screen.
Creating a new process and executing a program in it is no problems, the problem is that I can't seem to capture the output from it in the parent process.
Code:
//digenv
//C++arl 2011-03-24
#include <stdio.h>
#include <sys/types.h>

I'm currently experiencing some serious issues with WRITE performance on a RAID-1 array. I'm running Ubuntu 10.04 64 bit server with the latest updates. To evaluate the performance ran the following test: [URL]... (great article btw!) Using dd to measure, write performance is only at 8.7 MB/s. Read is great though at 74.5 MB/s. The tests were ran straight after rebooting and I have not (YET!) done any kernel tuning or customization, running the default server package of the Ubuntu kernel. Here's the motherboard in the server: [URL]... with a beta bios to support drives over 300GB.
[code]...
As you can see from the bo column there is definitely something stalling. As per top output, the %wa (waiting for i/o) is always around %75 however as per above, writes are stalling. CPU is basically idle all the time. Hard drives are quite new and smartctl (smartmontools) does not detect any faults.

I would like to set up three directories-
1) RW public directory
2) R-public, RW-me
3) Private dir (my /home/me)
BTW, I set all file permissions (recursively) to 777 until I can get this to work...
1) So far I have got 1 samba share working Read only with the following: [Music]
[Code]...
Guests can read it okay but user 'JoeBleaux' can't write to it...
2) I can't get the public read-write dir to work, again, it can be read by everyone but no one can write to it. Here's my broken config for this share: [Uploads]
[Code]...
3) I can't get the private dir to work. Here's my broken config for this share: [HomeDir]
[Code]...

I'm trying to write a .sh script that allows me to run multiple other .sh scripts at once.
My problem occurs within a Variable:
I have set
S1 to S7 to be the name of the .sh
A="7"
B="S$A"
C="$S$A" <- and this is where my problem is
I want C to be the content of S7 till S1 but if I run this line it will of course look for the content of S and link it with the content of A.
How can I correct this?
Edit:
WHERE="/home/X/Y/"
SH=".sh";
A="7";
B="S$A";
C="$B";

I know, I know..."How long is a piece of string"?
I have one of these devices:
[URL]
Of course, it's Windows only, and XP only at that. However, the data that needs transferred between the device and the computer should be fairly basic, unless it offloads a lot of processing to the computer. I'm not a programmer, nor do I play one on TV, but I have written some fairly complicated microcontroller programs and some basic Java GUIs. Besides writing the actual code, how hard is it to do whatever needs done to make a Linux device driver, apart from the code to make the device work?

I'm learning PHP and I was curious about this. I've learnt about cookies and sessions, and I'd like to know - which one do you use for a shopping cart? What's the actual mechanism behind it? As the user builds up a cart full of stuff, is the data for that maintained on the server-side in a MySQL database or something?
