I run into a funny case I went to see some friends in another City and used their Samsung Tablet for some Skype Chatting and few Skype Calls.
When logging in I forgot to untick the "Save password" tick and when I left the city and travelled to my home I saw on my wife's Skype (who has my username) logged in that still my Skype keeps logged in. In other words Skype shows I'm online even though I was not really connected.
I remembered I forgot to logoff Skype from the Tablet, so any time the tablet was connected to the internet or restarted Skype started I was automatically logged in Skype. This was pretty annoying because many people write me when I'm in fact offline and the messages end up in the tablet and I'm not answering making truly a bad impression (many friends and relatives, think I'm rude for not answering and even started being angry with me without me knowing why …)
To solve the situation, I had to use /remotelogout Skype Chat Windows command which is not visible as standard commands:
/remotelogout
This command logout all users logged in any device ( Android / iPhones Mobile Phones etc.) so afterwards, one can be sure you're logged in just from one device (the current one from where you execute the command)
To be absolutely sure, there are no other devices logged in with your credentials there is also /showplaces command:
/showplaces
You have 1 online endpoints:
{6934eadb-3eec-e001-4bc6-064e0552018f} 'WINDOWSVM' (Windows Skype)
The standard commadns shown in Skype help with /help typed in on any userchat opened Window are:
/help
Available commands:
/me [text]
/add [skypename+]
/alertson [text]
/alertsoff
/help
However there is another less known Complete list of supported Skype (Hidden) commands you can use to imitiate most of GUI Skype motions + a lot of info you can get only via those commands, here it is:
| Command | Description |
| /add [Skype Name] | Adds a contact to the chat. For instance:/add alex_cooper1 will add that member to the chat. |

If you are logged in to Oracle SQL server with sqlplus and you're not sure to which Database, Tables, Object instances you have permissions to below 2 queries will be of use:
SQL> SELECT DISTINCT OWNER, OBJECT_NAME FROM ALL_OBJECTS WHERE OBJECT_TYPE = 'TABLE';
Query lists all queries in a Oracle table schema. Alternavite shorter way to do the query is via:
SQL> SELECT table_name FROM user_tables;
SQL> SELECT * FROM TAB;
Shows your own schema's all tables and views.
Other oracle useful query is the Oracle equivalent of MySQL SHOW TABLES;
SQL> SELECT table_name FROM user_tables;
It will also output info only for logged in user credentials, if you're logged in as oracle database administrator (DBA role) account and you would like to check what Instances are owned by any user lets say user GEORGI query should be;
SQL> SELECT DISTINCT OWNER, OBJECT_NAME FROM ALL_OBJECTS WHERE OBJECT_TYPE = 'TABLE' AND OWNER = 'GEORGI;
Other way to do it is via:
SQL> SELECT Table_Name from All_Tables WHERE OWNER = 'YOURSCHEMA';

Whether you tried running simultaneously more than 1 Skype clients by clicking twice on Skype Desktop icon or invoking Skype via Windows Start menu; You already have figured out that Skype on Windows is set-up by defaykt to only support one logged in Skype user.
In case you wonder why on earth someone might need to run in parallel few Skype accounts on one Windows PC, possible scenario is;;;
You work for a company and just for clarity you have to communicate with clients from one skype name and with another skype name to communicate to company management.
In Linux in Skype version this is not so and thus for people like me who come from Linux it is rather uneasy to not be able to login in second Skype instance, whether you go to a friend who already keeps logged in with his Skype user …
Thus this triggered me to research a bit if simulatenous user login is possible?
Yes it is possible and very easy, to do so the user has to run manually Skype from command line like so:
On 32bit PC hardware with 32 bit of Microsoft Windows issue in win cmd.exe (command prompt) from:
START -> RUN -> cmd.exe
cd C:\\Program Files\\Skype\Phone\\
C:\\Program Files\\Skype\\Skype /secondary
or to directly paste in command prompt:
“C:\\Program Files\\Skype\\Phone\\Skype.exe” /secondary
If you are on a 64bit machine run in cmd prompt:
“C:\\Program Files (x86)\\Skype\Phone\\Skype.exe” /secondary
To easily run few instances of Skype in parallel, you can make shortcuts on Desktop. pointing to any of both above commands.
That's all now you can login as many skype users as you like on 1 Win PC. All parallel logged in users can receive and write messages. However you should bear in mind that situation with answering Skype calls is a bit complicated as you cannot speak in parallel through different logged in skype users. Anyhow whether you have to react on Skype voice / video calls incoming in similar or same time from 2 skype accounts, you can use – Set Skype Call on Hold functionality and hence keep voice video in parallel with different skype accounts.

Tuesday, January 10th, 2012I've experienced plenty of problems with Pulseaudio and Skype output sound hell crappy. This stupid proprietary program Skype is a total crap … Anyways again thanks to ArchLinux's wiki, I've used the two mentioned steps to fix all this Skype in / out problems …
1. Fix problems with Glitches, voice skips and crackling In file /etc/pulse/default.pa its necessery to substitute the line;
load-module module-udev-detect
with
load-module module-udev-detect tsched=0
2. Resolve Choppy sound in (Pulseaudio) -> Skype
In /etc/pulse/daemon.conf two lines has to be also substituted:
; default-sample-rate = 44100
Should become;
default-sample-rate = 48000
3. Change /etc/default/pulseaudio to allow dynamic module loading
It is a good idea to the default settings from DISALLOW_MODULE_LOADING=1 to DISALLOW_MODULE_LOADING=0 .This step is not required and I'm not sure if it has some influence on solving sound in / out problems with Skype but I believe it can be helpful in some cases..
So in /etc/default/pulseaudio Substitute:
DISALLOW_MODULE_LOADING=1
to;
DISALLOW_MODULE_LOADING=0
4. Restart PulseAudio server
After the line is changed and substituted a restart of PulseAudio is required. For PulseAudio server restart a gnome session logout is necessery. Just LogOff logged Gnome user and issue cmd:
debian:~# pkill pulseaudio
This will kill any left pulseaudio server previous instances.

Friday, August 5th, 2011One of the servers running Cpanel has been suspended today and the Data Center decided to completely bring down our server and gave us access to it only through rescue mode running linux livecd.
Thus I had no way to access the Cpanel web interface to suspend the “hacker” who by the way was running a number of instances of this old Romanian script kiddies brute force ssh scanner called sshscan .
Thanksfully Cpanel is equipped with a number of handy scripts for emergency situations in /scripts directory. These shell management scripts are awesome for situations like this one, where no web access is not avaiable.
To suspend the abuser / (abusive user ) I had to issue the command:
root@rescue [/]# /scripts/suspendacct abuse_user
Changing Shell to /bin/false...chsh: Unknown user context is not authorized to change the shell of abuse_user
Done
Locking Password...Locking password for user abuse_user.
passwd: Success
Done
Suspending mysql users
warn [suspendmysqlusers] abuse_user has no databases.
Notification => reports@santrex.net via EMAIL [level => 3]
Account previously suspended (password was locked).
/bin/df: `/proc/sys/fs/binfmt_misc': No such file or directory
Using Universal Quota Support (quota=0)
Suspended document root /home/abuse_user/public_html
Suspended document root /home/abuse_user/public_html/updateverificationonline.com
Using Universal Quota Support (quota=0)
Updating ftp passwords for abuse_user
Ftp password files updated.
Ftp vhost passwords synced
abuse_user's account has been suspended
That’s all now the user is suspended, so hopefully the DC will bring the server online in few minutes.

Wednesday, September 30th, 2009Some time ago, I asked myself if there is a SSH/Telnet supporting Terminal program
for Windows which enables you to have a tabs with the opened connections to a number
of servers. Well after some time spent looking, I’ve came across the solution
which concludes to a nice PuTTy wrapper program called Putty Connection Manager .
Putty Connection Manager requires you to have PuTTY installed all it does it runs a multiple putty instances
each one opening in a nice multi tab windows, like the good old linux gnome-terminal.
Cheers!END—–
