I'm trying to write shell script to use etc/init.d In fact, my application has written by java and I have made the fat.jar (etest.jar)file as executable one and after I wrote the small script to run it background (etestruner.sh) that is,
I am a final year student doign Computer systems engineering and just been introduced to linux. While still strugling to catch up with the commands, I am now given an assignment under shell scripting.I seriously am strugling to understand this question, can you please assist me.Here follows the assignment:

Does anybody know why isn�t anything on the /var/log/boot.log file. After the boot I saw some services that fail to load and looking for more detail data on the boot.log file I couldn�t found anything this file is empty. This is My syslog.conf file:

I'm trying to install postgresql 8.3 on Ubuntu 8.04 LTS server and I'm running into problems starting it. Commands I've done # apt-get install postgresql postgresql-common Things I've tried Starting it manually
# /etc/init.d/postgrsql-8.3 start
Nothing appears in my /var/run/postgresql When I try and start psql as the postgres user I get the following error psql: could not connect to server: No such file or directory Is the server running locally and accepting connections on Unix domain socket "/var/run/postgresql/.s.PGSQL.5432"? I've been following the docs at: https://help.ubuntu.com/community/PostgreSQL
cups does not start with the server. When I try to start from the terminal I get the error message
cupsd: Unable to read configuration file '/etc/cups/cupsd.conf' - exiting! cupsd: Child exited with status 1!
The log files show nothing. cupsd.conf exists. It is user - root and group - root with permissions set at 0644.
My interpretation of this is that the program is not launching from either boot or terminal for a fundamental reason. I do not quite see what that reason is .
I have installed vnc-server on my CentOS 5.6 virtual machine. I can connect to it with a java web browser so it seems to be working. However, I get the following error message when I start, stop or restart the vnc-server process. Quote: Starting VNC server: 1:ken xauth: timeout in locking authority file /root/.xauthkk661q
I have a large file that a process writes to. I would like to empty that file. If I delete it the process will stop writing to it. Just flush the content but keep the file.
I was copying an .avi file to an external hard drive and half way through the copy the drive reset and required remounting. Consequently I have an empty .avi file on the hard drive. I tried to recopy the file and overwrite, but I keep getting 'Could not write to media/harddrive/filename.avi'. I tried to rename to file to be copied but got the same response, I cannot delete the empty file either, as I get an error telling I cannot delete it. I have tried to do this as the user and root with the same result.Any other file I tried to copy onto the external hard drive is fine, just this one zero length file and the file I was trying to copy, the original of the file. I also tried to delete the file on another computer but couldn'tExternal hard drive is a WD elements ntfs, which works great except for this glitch.
I am using embedded Linux. File open is successful. The file has all the permissions. It is present in current directory too. The size is about 27KB. But s.st_size says it is zero.
Brand new to Linux. Sort of got thrown in front of the bus if you know what I mean. The company I work for has a Linux server running CentOS 5.4 Company uses Linux for their Email, FTP and Web Server. Have been here a few years dabbling in and out of Linux and now that the old Admin has left the company.....I need to learn it ASAP. The server has run pretty solid until today.
The email server runs SendMail and SpamAssasin. Received lots of complaints today regarding extra SPAM. Noticed that SpamAssassin was not running. Tried to restart it through the WebMin tools and got the following error: Starting spamd: child process [3956] exited or timed out without signaling production of a PID file: exit 255 at /usr/bin/spamd line 2588.
I have setup a local repository containing several .rpm files. I created a comps.xml file outlining the category and groups for the local repository. However, when I issue the yum grouplist command, I get the following error:
Failed to add groups file for repository: localRepo - comps file is empty/damaged
However, if I try to install one of the the packages in the repository, it works just fine.
Here are the steps I took to create the repodata:
The comps.xml and repository are stored in the directory: /var/www/html/myrepo/x86_64 cd /var/www/html/myrepo/x86_64 createrepo -g comps.xml .
I having been searching for a way to create an empty or blank iso file, so that I can mount it, and have a backup application think it's a blank CD. I am tired of wasting CD's by having the application write a recovery CD, just for me to turn around and export it to an iso image to be stored in a online archive, and then throw away the physical CD.
Using awk I pull the first field of a random line from my datafile.myvar1=`awk -F" " 'NR=='$randline' {printf "%s", $1}' myfileThis works fine. The problem is there will be empty lines at the end of the file. Rather than using awkto filter out blank lines I would like to figure this out first.So I test $myvar1 for a blank string after setting $randline to one that I know is blank:test -z "$myvar1" && echo "true" || echo "false"But, this returns "false"? So the string is not zero length. Why? It's a tab-separated file. Is awk storing the tab with the $1 field or something.This is where I get headache. I try to echo my variable to see what it looks like.
echo "$myvar1" outputs: nothing echo "My variable is [$myvar1]" outputs: [y variable is [
Why is the closing bracket at the beginning? What character could be stored in $myvar1 that would do such a thing and how did it get there?
I just installed proftpd using webpin but when i tried to gonfigure it ,i figured out that the configuration file proftpd.conf is empty, is it about permission ?i just dont get it!
My cron job is executing the below mysqldump command but it produces an empty sql file. However, when I run from the command line, it works as expected.
I just installed FC10 and then used yumex to install the vsftpd FTP daemon package. I'm using the vsftpd.conf file that came with the distribution, and its almost identical to one I copied from my FC2 machine's working set-up. When I try to FTP in as a known system user I'm presented with my home directory /home/myusername/. The directory appears empty to the FTP program, but isn't in reality. I can't upload a file to the empty home directory. I can move up the directory hierarchy to /home/, but again that appears as an empty directory.
I don't think it's a vsftpd.conf file issue. I've tried everything I can there. Could it have something to do with permissions? I fiddled with those, but couldn't make an FTP directory listing work.
after update f12 to f13 geany stopped to work correctly on remote storage (sftp). Geany opens file correctly, but when I try to save, it saves empty file. I tried "notepad" and "gedit", they work good on f13. Geany on f12 worked correctly too.
Greetings, I have installed a VMware host on Windows 7 64bit and followed with a 10.04LTS 64 bit guest install. Everything went smooth. I have used VMware before, but the other way around.. Linux host and Windows guest.
So this time I am installing the VMWare tools on the guest, ubuntu 10.04, but it seems to be failing. The vmware tools install ran fine the first time with no errors, but I was getting the follwoing error after logging into the Ubuntu guest afterwards.
Could Not Apply the Start Configuration for Monitors Error Line 1: Char 1 Whitespace or empty file
So I re installed the VMware tools once again, but still the same.
I am hoping that someone here has come across this before and hs a workaround. I don't think the vmware tools was installed correctly.
Does anyone know why files in my /tmp directory are not able to rm even using root login? not only that, I can't even chmod or do anything to files in /tmp directory... it always saying "read only file system" warning
I'm installing Wordpress and I want Hosting Multiple Sites with them. For that I need modify the httpd.conf file but it's empty. Where I can make that changes? These are the changes:
1. Type: LoadModule rewrite_module /libexec/mod_rewrite.so 2. Find the <VirtualHost> section in the httpd.conf file. 3. Find a line in the <VirtualHost> section of the httpd.conf that looks like this: AllowOverride None 3. Replace that line with this line: AllowOverride FileInfo Options 4. On a new line, type ServerAlias *.[URL]. 5. Save the httpd.conf file and close it.
I installed MRTG some hours ago. Everything works fine (disk, cpu,..), except the network graph. For this graph, it's only work for ~3 cycles (15min), then... nothing.
This is the part of mrtg.cfg:
Code:
The number for eth0 is 3
Code:
SNMP is running:
Code:
Crontab is configured for mrtg (and seems it's not the problem because the other graphs works well):
Code:
In attachement is the graph for the memory (working!) and .. for the network, as you can see, only one small pic at the beginning.
I was checking my server and found a /net directory with nothing visible inside. The mysterious directory is /net and I checked to make sure nothing was mounted to it: [root@mysql /]# mount /dev/sda1 on / type ext3 (rw) proc on /proc type proc (rw) sysfs on /sys type sysfs (rw) devpts on /dev/pts type devpts (rw,gid=5,mode=620) tmpfs on /dev/shm type tmpfs (rw) none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw) sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
In our cluster, both the server and worker had been gone to swap and the performance is extremely slow. Although currently the memory is free but I don't know why the in the swap area is still being there and ubuntu doesn't move them to the memory and empty the swap.
On the other hand, when I run
Code: sudo swapoff -a on the server it says: Code: mahmood@server:~$ sudo swapoff -a
