Its really annoying, when some Anti-Virus software or application updates itself and requires a Windows restart. It is even more annoying when you have 50 windows opened and suddenly they start closing one by one. In such cases it is precious to know there is way to Cancel Windows Shutdown using command line:
Just press Windows (button) + R: type in;
shutdown /a
and press enter.
That's it a quick cmd prompt will flash through the screen and Windows will stop shutdowning 🙂 Enjoy
Its probably not so common problem among new-comer Linux users / admins but sooner or later even those who haven't will cat by mistake (or on purpose) some binary file end result will be physical console / terminal / SSH Client (lets say PuTTY) will display some non-sense characters and whether typing you will type in some "alien language" characters this continues until you close up console and re-login. Of course its not such a big problem to re-login or (kill active SSH session).
But there is no sense to do that and loose time and most importantly loose your logged in session (especially if you have hopped to 4 ssh sessions and you forgot to run GNU / screen). Thus its handy to know about
command. Once issued in most cases TTY messed up characters gets fixed up. However if even reset doesn't fix it, there is another "hack" to resolve it with no need for relogin. This is an old hack from my old Linux days and not so popular among admins, here is how:
Type
cat
press Enter
and then press
then press Enter
and then again press
Nice hack isn't it ? 🙂
Almost no sane person and security aware person uses Internet Explorer still. However still in huge American companies it is heavily used. If you install Firefox or Google Chrome and by mistake you change default browser to one of them then it is worthy revert back default browser to Internet Explorer.
Here is how to do it;
Open Internet Explorer and navigate to:
Tools -> Interent Options -> Programs -> click on (Make Default)
Done
In general Linux has fame for being Virus Free Operating System. During the 13 last years as dedicated GNU / Linux user, I've seen Linux servers with binaries infected with Viruses, however the hosts, were severely messed hosts because noone updated them on time and script kiddy crackers has "hacked" multiple times. In lifetime one of my old testing computers got infected with Virus because of my mistake of running "suspicious" pre-compiled "cracker" software binaries with no MD5 verification and "questionable" websites…
I share this story because, I want to beat-up the Myth that Linux cannot have Viruses. It CAN but not very likely to happen 🙂
As a Desktop user over the last 10 years, even though I installed plenty of packages from third party sources and never happened to infect my computer with Virus – or at least if I infected I never knew it. A lot of popular MS-Windows Anti-Virus programs, has already ports for Linux. Just to mention few non-free Linux AV software providing install binaries;
Though risk of Viruses on Linux is so tiny, it is useful to have ANTI-Virus Software to check files received from Skype, E-mails and onse downloaded with Browser. I always prefer so until now I used Clamav Antivirus to keep an eye periodically on my Desktop Linux host and servers running mail servers (those who run Mail Servers know how useful is Clamav in stopping tons of E-mail attached Malware Viruses and Trojans).
I use mostly Debian Linux, so on every new server or Desktop one of first things I did was to install it, i.e.:
# apt-get --yes install clamav
...
Before I knew Clamav AV for Windows has GUI, anyways till recently I didn't know if there is some kind of free software AV Graphical frontend for Linux. I just found out about ClamTK
ClamTK is available in most Linux distributions from default package repositories
On Debian and Ubuntu to install it run common:
debian:~# apt-get --yes clamtk
...
On Fedora and CentOS Linux to install:
[root@fedora ~]# yum -y install clamtk
...
Its best to run it as root superuser (or via sudo) to make ClamTK able read all files or mounts on system:
hipo@debian:~$ sudo clamtk
ClamTK is very simple to use and there are only few configuration options;
ClamTK is very useful when used with mounted Samba Shared (Mapped) Windows drives to scan for Viruses and malware, i.e, after mounting share using cmd like:
# smbmount //192.168.2.28/projects /mnt/projects -o user=USERNAME
Yesterday I was on a birthday of a one girl Krisi she is 18 already. It was a standard teen party. Awful place, I drunk 3 beers and smoked a lot of cigaretes in general we discussed with some ppl Does the Lord exist things. Is evolution real is it possible at all things like this. There was one boy who was keen on Free Software GPL etc. I realized I’m a real psycho after I started to convince him Windows and M$ products are much better than free software :]. After 3 hours speaking like a 15 years m$ user. When walking back for home. I asked my self what the heck? What I did I’m real psycho ;]. Zuio and I broke 1 flowerpot when doing POGO on a Hipodil song. I eat some strange salad with hands ( I pretended to be a Bangla person ) :]. Nomen drunk a lot and got angry at a guy and proposed to start a fight:]. In 5:30 a.m. we were already at home. Our mood got fucked up a little when going back to home. In the morning Papi wake me up and suggested to go to a coffee, I aggreed as usual but I did misunderstood about the place where we decided to see, and waited on other place after that I realized I did a mistake and he meant we have to see each other in the Winter Theather not the Summer One (silly me). After that normal day I eat. I did some server descriptions, played mame in Nomen (I went his home). I was able to start gxmame to work in fullscreen in the end (my integrated video card is doing alot of problems about the games) but I found out the xmame -ef 1 option. That one rules.END—–
It was quite a peaceful day, I didn’t have a lot of work. Plamenko come home at 4:30. I went to see my grandmo.My grandmo said that there was some mistake and she has to pay for the last month much higher bill than avarageand somebody have to go to report this to the Local Electricity Office, so I take Plamenko’s bike and rided.I like riding bicycle, maybe I have to buy one after that I worked a little ( currently I have to move a dozenof websites sites from one server to another ). In 6:30 I have a walk with Mitko and we drinked coffee on the Chineese Restaurant. After from 08:00 to 10:30 I was home, and then I went out. I and Plamenko went to the Old Dobrich City to Mino’s coffee. I took Plamenko’s bike and used it to ride to a common places where Mitko and the other guys would probably be. I found them in the Central Park and we stayed there for some time. Sasho ( Saketo ), come and stayed with us and explained he’s trying to stop drugs until February. And he doesn’t take drugs since then, not much of the people believed him, but I really hope what he says is truth and God would help him to stop using drugs. Everything seems clear because The Lord is probably taking an eye on me :] So I Bless the Lord for his mercy! Blessed be Lord of Hosts!END—–
The last 3 days in the college we used to have a guest from the Arnhem Business Scholl: Job Thinke.He is a teacher in HRQM (Human Resource and Quality Management). We played a simulator. We choose abusiness to be in. Job, Bozhidar, and two graduating students from Arnhem ( one black girl and one guy from South Africa )were the teachers. We choose an industry (our group was some Open cars producing company). Every peson of the teamhad to participate in taking decisions and writting down the decisions in a decision forms every form was aboutmoney we would invest in things which would lead to accomplish a specific goals we had setted in the beginning of the game,things like hiring more employees promoting some of them etc. etc. were our work. The game was played 3 days and it waslike if we had run a 2 years long business. Our group mistake was that we always thought about things in short terms.In the end of the 2nd year of the game we had a discussion meetings with our higher level employees and it turns outthat we are the poorest team because we always thought about the company in short term instead of long term.During this 3 days there was also some funny games for developing concentration and thinking and improvingcommunication skills. In general I think the whole think was a great loss of time, but I’m a strange person …Most of the ppl liked involved from IBMS and Hotel Management liked the game very much.END—–
Nothing special. Last week went just fine thanks to the Lord ! Of Course :). It was mostly peaceful. What was interesting was a method our teacher at management choose to use to make us better understand ourselves. She said I want all of you to draw me a picture of how do you foresee yourself ten years from now :). We all was surprised but just as she requested we did draw the pictures. My picture had 4 possibly futures. In one of them I was with my wife and a kid in front of our house, on the other I was owning and leading an IT company. On one of them I was helping to get out of the terrible pit of depression, addiction to drug, alcoholism, telling them “Stop there is a reason to live, God Loves you!”. In the other case I was a Senior SysAdmin in a middle size/big company managing servers/clusters. Now we had to make a report explaining our picture. I just did make my report hope the teacher would like it. Yesterday, Bino came home and proposed to go out, we went out we saw Stoyan (who btw is a Brother in Christ). Later we saw Dancho a friend of mine (a communist). First we started a normal talk later the talk just transformed into a terrible and useless argue I did a mistake not stopping whenever I had to. And in the end we decided not to see each other because it’s bad for both of us. Later Alex (an ex class-mate) called me and we went we had a walk in the central park and talked ’bout if I can say it like this “the life, the universe, and everything else” :). The next few weeks outline to be a tough one. We are going to have a lot of exams 8 or 9 ! We had a lot of projects and assignments but still I trust on the Holy one to help me make all of them and do just fine on the exams just like he helped me the last semester and the previous year.END—–
