repo for liferay plugins for eclipse

Please add
"Latest Stable Release URL (1.6.x) - http://releases.liferay.com/tools/ide/latest/stable/"
to the addons"

Compress and scp on the fly

tar cvfz - docs-dm  | ssh joseph@192.168.21.189 "tar zxvf -"

tar cfz - docs-dm  | ssh joseph@192.168.21.189 "tar zxvf -"

Step 1 :- Create a tar file that output to stdout
               tar cf -, the “-” is to output to stdout

Step 2 :- Pipe the output to an ssh connection that execute a command that read stdin and pass it to tar
          tar xvf -, where “-” is stdin.

------------------------------------------------------------------------------------------------
To change the directory and copy

tar cvf - portal-ho/  | ssh joseph@192.168.21.211 'cd /home/joseph/.  && tar xvf -';
 

Recursively find the latest modified file in a directory

find . -type f -printf '%T@ %p\n' | sort -n | tail -1 | cut -f2- -d" "

%T@ gives you the modification time like a unix timestamp,

sort -n sorts numerically, 

tail -1 takes the last line (highest timestamp), 

cut -f2 -d" " cuts away the first field (the timestamp) from the output. 

Using grep and Ignoring Case (Case Insensitive grep)

grep -i "ErRoR" /opt/alfresco/tomcat/logs/catalina.out > ErrorFile.txt

how to compress and scp files live

 tar zcvf - ho-dm   | ssh root@192.168.21.189 "cat > /home/joseph/test/ho-dm.tar.gz"

"WQS unable to connect to repository: Unauthorized"

Solved the issue of getting message "WQS unable to connect to repository: Unauthorized" for the Document Management
this happens when you change the admin password, the changed password is not getting reflected in some process.
Solution is to
edit "/opt/alfresco/tomcat/shared/classes/alfresco/extension/wqsapi-custom.properties"
and enter the  correct password

ie, if you forget the admin password for a running system with the log message "WQS unable to connect to repository: Unauthorized", then you can get it from "wqsapi-custom.properties"

Removing commented lines and display

grep -v '^#' samba.conf 

here -v is for inverse 

ie -v, --invert-match
              Invert the sense of matching, to select non-matching lines.

Will print all lines EXCEPT those that begin with a # char. 

you can change the comment char to whatever you wish.

egrep -v '^(;|#|//)' filelist 

If you have more than one comment char , use the above command 

In regex, ^ indicates the beginning of a line, and $ the end of a line,

So ^$ specifies lines where the start of line character and the end of line character are right next to each other.

SSH Automatic Login

SSH Automatic Login

Here are the steps:

    Create a public ssh key, if you haven’t one already.
    Look at ~/.ssh. If you see a file named id_dsa.pub then you obviously already have a public key. If not, simply create one. ssh-keygen -t dsa should do the trick.
    Please note that there are other types of keys, e.g. RSA instead of DSA. I simply recomend DSA, but keep that in mind if you run into errors.
    Make sure your .ssh dir is 700:
    chmod 700 ~/.ssh
    Get your public ssh key on the server you want to login automatically.
    A simple scp ~/.ssh/id_dsa.pub remoteuser@remoteserver.com: is ok.
    Append the contents of your public key to the ~/.ssh/authorized_keys and remove it.
    Important: This must be done on the server you just copied your public key to. Otherwise you wouldn’t have had to copy it on your server.
    Simply issue something like cat id_dsa.pub > .ssh/authorized_keys while at your home directory.
    Instead of steps 3 and 4, you can issue something like this:
    cat ~/.ssh/id_dsa.pub | ssh -l remoteuser remoteserver.com 'cat >  ~/.ssh/authorized_keys'
    Remove your public key from the home directory on the server.
    Done!
Also check the permission of .ssh/authorized_keys it should be "600", otherwise it will not work
    You can now login:
    ssh -l remoteuser remoteserver.com or ssh remoteuser@remoteserver.com without getting asked for a password.

That’s all you need to do.

#############
All in one step

ssh-keygen -t rsa

cat ~/.ssh/id_dsa.pub | ssh -l remoteuser remoteserver.com 'cat >> ~/.ssh/authorized_keys'

cat ~/.ssh/id_dsa.pub | ssh -l joseph 192.168.20.15 'cat >> ~/.ssh/authorized_keys'
cat ~/.ssh/id_dsa.pub | ssh -l joseph 192.168.21.164 'cat >> ~/.ssh/authorized_keys'
 
     or

cat ~/.ssh/id_rsa.pub | ssh -l joseph 192.168.20.15 'cat >> ~/.ssh/authorized_keys'

cat ~/.ssh/id_rsa.pub | ssh -l dmbackup 192.168.20.17 'cat >> ~/.ssh/authorized_keys'

cat ~/.ssh/id_rsa.pub | ssh -l dmbackup 128.52.1.15 'cat >> ~/.ssh/authorized_keys'

rsync notes

rsync
  commands to execute rsync is rsync -r -a Source/. /home/joseph/rsyncDesFold

Points to be careful with when using Rsync?

• Be careful with the --delete command. If your using a source dir that is not mounted (nfs,cifs,etc) but the mount for the dir is still there then you will sync your blank dir. All remote files will be deleted.
• Be careful with slashes after the dir names on the source. A slash after the dir name compared to no slash after the dir name will do 2 totally different things.

Difference in giving "/"
What if we  wanted to not just copy all of the files under /sourcedisk/, but also the /sourcedisk/ directory name. Just leave off the last "/" after the "/sourcedisk" directory name. This will tell rsync to copy the directory name and all files under that directory. On the remote server you will then see the directory structure /backups/sourcedisk/.

To reflect the deleted files to be removed from the destination

rsync -r -a -v -z --delete /opt/src/. /home/joseph/rsyncDesFold
-r => recurse into directories
-a => archive
-v => increase verbosity
-z => compress file during transfer

rsync -r -a -v -z --delete     /home/joseph/Projects joseph@192.168.21.78:/home/joseph/.
this will copy the "Project" Folder entirely to remote server /home/joseph


 rsync -r -a -v -z --delete     /home/joseph/Projects/. joseph@192.168.21.78:/home/joseph/.
This will copy the contents of "Project" to the remote server /home/joseph. ie you will not have folder "Project" in remote server, but you will see the contents of it in /home/joseph/

IPTABLES :- Open Up Remote Ports

iptables -A INPUT -i eth0 -p tcp --destination-port 3306 -j ACCEPT

# The above line accept connection to port 3306

To see which ports are being used

netstat -ntl

-n = Numeric 

-t = 

-l =  interface

Redirect to a different port using IPTABLES

 iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8080 

-t = table 

-A = Appending 

PREROUTING:- Is the chain which is responsible for packets that just arrived at the network interface
So far no routing decision has taken place, therefore it is not yet known whether the packet would be interpreted locally or whether it would be forwarded to another machine located at another network interface. After the packet has passed the PREROUTING chain the routing decision is made.


-p = protocol

--dport = destination port 

-j =  
 -j, --jump target
This specifies the target of the rule; i.e., what to do if the packet matches it.  The  target  can  be  a  user-defined  chain  (other than the one this rule is in).

--to-port
--to-ports port[-port]
              This specifies a destination port or range of ports to use: without this, the destination port is never altered.  This is  only valid if the rule also specifies -p tcp or -p udp.
 
Test it by 

iptables -t nat -L

to check which port is used

netstat -ntl

 

 
Note:-
The chains PREROUTING und POSTROUTING are the most important ones. As the name implies, the PREROUTING chain is responsible for packets that just arrived at the network interface. So far no routing decision has taken place, therefore it is not yet known whether the packet would be interpreted locally or whether it would be forwarded to another machine located at another network interface. After the packet has passed the PREROUTING chain the routing decision is made
