Screen

Screen as you may already know is a tool to handle multiple sessions in one window... very useful to remove load from your personal laptop.. avoid having to connect everyday to all those sessions... and having the capability to left processes running =D ... 

well on Linux most of the time is already installed on AIX is never so install it... but there is a little issue on the code that need to be fixed to successfully install the tool on AIX... 

Download the tool from...
ftp ftp.software.ibm.com
anonymous
cd aix/freeSoftware/aixtoolbox/RPMS/ppc/wget
bin
prompt
get wget-1.9-2.aix5.1.ppc.rpm
quit
rpm -hUv wget-1.9-2.aix5.1.ppc.rpm
wget ftp://ftp.software.ibm.com/aix/freeSoftware/aixtoolbox/RPMS/ppc/screen/screen-3.9.10-2.aix4.3.ppc.rpm
rpm -hUv screen-3.9.10-2.aix4.3.ppc.rpm
wget ftp://ftp.gnu.org/gnu/screen/screen-4.0.3.tar.gz
gunzip screen-4.0.3.tar.gz
tar -xvf screen-4.0.3.tar
cd screen-4.0.3
vi misc.c

changed following part in order to get over it:

,----[ misc.c - original part ]
| #else /* USESETENV */
| # if defined(linux) || defined(__convex__) || (BSD >= 199103)
| )
| setenv(var, value, 1);
| # else
| setenv(var, value);
| # endif /* linux || convex || BSD >= 199103 */
| #endif /* USESETENV */
| }
`----

Then I used the dirty hack by adding ", 1" to the second setenv-statement directly.

,----[ misc.c - altered part ]
| #else /* USESETENV */
| # if defined(linux) || defined(__convex__) || (BSD >= 199103) ||
defined(__aix__)
| setenv(var, value, 1);
| # else
| setenv(var, value, 1);
| # endif /* linux || convex || BSD >= 199103 */
| #endif /* USESETENV */
| }
`----

That "solved" the error-message above.

./configure
make
make install



Now that the tool is installed here some useful commands

ctrl+a	Access to the screen command line...
p	previous
n	Next
0-9	Jump with ID
w	List open consoles
[	ScrollBack” (ESC to finish)
d	detached (will appear the word [detached])
r	retach (If there are many open session will appear the list, just select the ID to open Type "screen [-d] -r [pid.]tty.host" to resume one of them.”
X	Lock
:	set password
c	open new terminal
A	rename the current session
screen –x	share a screened session without detaching
k	kill session
\	Terminate session
:multiuser	enable multiuser mode

Now to have a very nice .screenrc just copy paste the following and add your servers

autodetach on # Autodetach session on hangup instead of terminating screen completely

startup_message off # Turn off the splash screen

defscrollback 30000 # Use a 30000-line scrollback buffer

scrollback 30000

termcapinfo xterm ti@:te@

vbell off # turn off visual bell

caption string "%?%F%{= Bk}%? %C%A %D %d-%m-%Y %{= kB} %t%= %?%F%{= Bk}%:%{= wk}%? %n "

hardstatus alwayslastline

#hardstatus string '%{= kG}[ %{G}%H %{g}][%= %{= kw}%?%-Lw%?%{r}(%{W}%n*%f%t%?(%u)%?%{r})%{w}%?%+Lw%?%?%= %{g}][%{B} %d/%m %{W}%c %{g}]'

hardstatus string '%{= kG}[ %{R}%t %{g}]%= %{g}[%{B} %d/%m %{W}%c %{g}]'

screen -t prod-a ssh prod-a

screen -t prod-b ssh prod-b

screen -t prod-c ssh prod-c

screen -t prod-d ssh prod-d

that will create a nice screen and launch all the servers and if you have SSH trusted keys automatically connect to all of them ;) and look sort of like this

 

 and if you hit [ ctrl+a "  ] you will be able to select your server from there
