I'm currently looking for an opensource web based inventory. I saw a few like GLPI and OCS Inventory NG but don't have much idea about it as I have not used one before. Please give your suggestions.
My requiremets:

I have a file which consists of a URL. I'm trying to get the URL from that file using a shell script.
In the file, the URL is like this:
('URL', 'http://url.com');
I tried to use the following:
cat file.php | grep 'URL' | awk '{ print $2 }'
It gives the output as:
'http://url.com');
But I need to get only url.com in a variable inside the shell script. How can I accomplish this?
I have been presented with a server running Ubuntu 12.04 LTS server edition.
This machine was in use earlier for a web application and also has many other applications configured in it. Now, I want to remove all the un necessary applications from it like apache2 etc. and do a fresh start for installation of the new application.
Now, the problem is how can I determine what applications i.e. packages are installed in it, and how can I disable/uninstall and optimize this server.
After uninstalling the packages I want to optimize it to disable Packages for Securing it much like point number 3 in the link here.
But it's not for Ubuntu.

I want to have a configuration in my Ubuntu system so that if the cpu processing exceeds 90%, it gives a beep sound. Is this possible?
Also, where else can this beep sound be used? Can it be used if the hard disk utilisation exceeds 80% ?
I have configured SNMP Agent in my system with ip address 192.168.1.1 I have configured SNMP Agent in it using the following tutorial
I have modified the lines as follows
In the file /etc/snmp/snmpd.conf
rocommunity public 127.0.0.1
rocommunity public 192.168.1.0/24
rocommunity public 192.168.2.0/24
In the file /etc/default/snmpd
SNMPDOPTS='-Lsd -Lf /dev/null -u snmp -g snmp -I -smux -p /var/run/snmpd.pid'
When I try to use the snmpwalk command from the system with ip address 192.168.1.1 it works fine.
Ex: A chunk of the commands output:
iso.3.6.1.2.1.1.1.0 = STRING: "Linux devenv 3.5.0-23-generic #35~precise1-Ubuntu SMP Fri Jan 25 17:13:26 UTC 2013 x86_64"
iso.3.6.1.2.1.1.2.0 = OID: iso.3.6.1.4.1.8072.3.2.10
iso.3.6.1.2.1.1.3.0 = Timeticks: (74328) 0:12:23.28
iso.3.6.1.2.1.1.4.0 = STRING: "Me <[email protected]>"
iso.3.6.1.2.1.1.5.0 = STRING: "devenv"
iso.3.6.1.2.1.1.6.0 = STRING: "Sitting on the Dock of the Bay"
iso.3.6.1.2.1.1.7.0 = INTEGER: 72
But when I try to use snmpwalk through a different system with ip 192.168.2.1 it gives No response from 192.168.1.1. Please Help.
snmpwalk -c public -v1 192.168.1.1 | less
PS I have configured the same steps on the machine with ip address 192.168.2.1. Or is there any other program that will be used.
EDIT 1.
Did netstat here is a screenshot
Im trying to use wireshark in my test enironment where I have two VM's with ip address 192.168.0.1 and 192.168.0.2
Im trying to monitor the data of the machine 192.168.0.2 from the machine at 192.168.0.1 using wireshark with tcpdump I got to know from the Tutorial Here.
Now, I made the pipe using the command
mkfifo /tmp/pipes/cap_fwd
It was created but when I try to do the second step that is ssh to the machine to run tcpdump and redirect its output to the pipe it doesn't work as the SSH doesn't gets completed the cursor keeps on blinking and doesn't gets executed. See the image below.
P.S. When I try to get the output of tcpdump on a normal file it does it easily so I believe the pipe is not working here. Please Help.
EDIT 1
1.I have checked the permission of the pipe and set it to full permissions for now.
2.I have created the pipe on my machine at ip 192.168.0.1 do I have to configure anything at the machine on 192.168.0.2
EDIT 2
Comment on the tutorial website by one of the user I'm having the same problem.
i tried to run it on my openwrt box, from ubuntu 10.10, but when i execute the command ssh [email protected] -p 443 “tcpdump -i eth0 -s 0 -U -w – not port 443″ > /tmp/pipes/cap_fw nothing happens (it should ask me the pw i suppose, but it doesn’t), it acts like if i didn’t press Return… the dropbear daemon is running on port 443 with pw login (no certificate)
Also he added later
it was only a problem of not using certificates with ssh, now it works correctly thanks!
Is this really the case of not using certificates as I too am not using any certificates for ssh.
My network uses static IP addresses and has a router. I used wireshark to detect a lot of arp requests from a single system, which seems to be running abnormally to me.
As I'm new to wireshark I don't know how to solve this problem. Please Help.
Here's a screenshot:
Is this behavior normal?
Its ip address is 10.0.0.6 and routers ip is 10.0.0.1
P.S. earlier rsyslog was configured on the system which sent logs to the system at the ip address 10.0.0.5
I'm trying to build a shell script which can automatically detect malware, backdoors and rootkits and I'm trying to research for it. I found some of the things like
find . -name “*.js” | xargs grep -l “eval(unescape”
find . -name “*.php” | xargs grep -l “eval(base64_decode”
But I dont find only these relevant to just find for .php and .js files and try to see if it consists of malware. Can anyone please help me to give a general idea that I can use for the script so that it can do the work of malware, backdoors and rootkits detection. More precisely to say how can one find these malwares, backdoors and rootkits on a ubuntu system. Thanks.
Im using Ubuntu server edition. In that it's configured to use ip address provided by DHCP. Now, I want to edit the resolv.conf file so that it points to the nameservers that I want to define. Obviously editing the resolv.conf file directly will not work as the changes will get overwritten. I also tried a different approch to edit /etc/resolvconf/resolv.conf.d/head and adding nameserver entries there that worked for me but it is said that it is not recommended. So I want to know how can I add nameserver entries if my machine is configured to use DHCP. I believe I will have to edit /etc/network/interfaces I tried a lot of tricks but nothing seems to work. Also is this possible to add nameserver if using DHCP?
I was having an issue in which the time my ubuntu machine was showing is 5 hours ahead of my standard time. So I installed ntpd for that using
apt-get install ntp
after that I restarted ntp but still my time is 5 hours ahead of my standard time in India. Please Help.
I want to configure rsyslog on a centralised server so that all the logs of clients are stored at one place now the problem I'm having is I dont know how to implement rsyslog so that it creates logs based on programmes on client machines i.e. like 'httpd' etc. and save them in different files i.e. '/var/log/httpd.log' and while it sends the log to the remote server the files should be saved like '/var/log/ip-address of host/httpd.log' I have these two problems
I hope I made my question clear. Please help.
For creating log based on programme I believe I will have to use something like on client side
if $programname == 'httpd' and $syslogseverity <= '6' then /var/log/httpd.log
if $programname == 'httpd' and $syslogseverity <= '6' then ~
I also found this question but it doesn't completely solves my problem
I want to create a custom table using iptables so that I can add my custom chains in it. But I doesn't see any option to do that. I tried to search for it but didnt found anything. Please Help.
I have some important documents that I need to protect from anyone else having access to my machine.
The problem being the other persons have access to my machine via root account so changing the file permissions is not a option for me. I have seen apps like cryptkeeper but I was wondering can I password protect my files/folder by command line mode in ubuntu.
Is it possible to determine the IP addresses of systems within a network using a bash script? And how?
While trying to install apache version 2.4.4 using the following method:
Source: http://zhuojun.info/?p=1121
Before installing Apache 2.4.4, you should install PCRE, otherwise it will not succeed. The process of installing PCRE is simple. After you downloaded it, run in terminal next commands:
sudo ./configure sudo make sudo make installDownload APR and APR-Util from http://apr.apache.org, unpack them to Apache directory,
/srclib/aprand/srclib/apr-util(no version numbers in the directory names) and type following commands to install Apache:sudo ./configure --with-included-apr sudo make sudo make installType following command to start Apache:
sudo /usr/local/apache2/bin/apachectl startThere may be something wrongs like:
/usr/local/apache2/bin/httpd: error while loading shared libraries: libpcre.so.1: cannot open shared object file: No such file or directoryType following command to see httpd’s shared library dependencies:
ldd httpdFound "libpcre.so.1 => not found", then type the following command to update links:
sudo ldconfigRestart Apache and should work.
Everything seemed fine but when I tried to start the apache service it gives error:
root@server1:/usr/local/apache2/bin# /etc/init.d/apache2 start
* Starting web server apache2 /usr/sbin/apache2: symbol lookup error: /usr/sbin/apache2: undefined symbol: apr_ldap_url_parse
Action 'start' failed.
The Apache error log may have more information.
[fail]
I tried to install the apr again but nothing seems to work. Please help.
The Apache log shows something like this:
[Mon Jun 17 10:31:08 2013] [notice] Apache/2.2.22 (Ubuntu) PHP/5.3.10-1ubuntu3.6 with Suhosin-Patch configured -- resuming normal operations

I need to install the latest versions of apache, php and mysql that are available on their websites, but the problem is that apt repositories don't have these updates versions yet.
Versions that I want: Apache 2.4.4, PHP 5.4.16 and MySQL 5.6.12.
Versions available via apt: Apache 2.2.22, PHP 5.4.15, MySQL 5.5.31.
Ubuntu doesn't support the above versions of packages. Please, I want help! Thanks!
P.S. Tasksel also doesn't have these versions of packages yet.
I want my system to act as the central system for the rest of my network of 10 PCs. I also want to monitor what's going on, and monitor the activity of other systems. So how can I do this? What are the tools I need to monitor; just using top or any bandwidth monitoring tool is the only thing required, and how can I use my system as a centralized server for rest of the systems?
I want to configure NAT for my network of 10 computers so that the data is transmitted via a single pc.
Can anyone give a good tutorial for it?
