vim and PUTTY

Filed Under Command line, Fix, Linux, Unix | 1 Comment

Most of “ux” users and administrators use remote terminal to connect to administrared machine.

One of the popular choises, minly because of it’s portability is PuTTy only putty.exe is needed and no installation is required. In addition it is free.

Downside is that sometimes there are problems with terminal emulation – not necessary coming from putty, but still annoying.

One of my problems is that when vim is in insert mode arrow keys do not work. For long time I was no able to find solution to the problem, but finally i found one. Just type this in your home folder:

echo syntax enable > ~/.vimrc

This did the trick for me. Hope it helps to you too.

“UPS Virus” – UPDATE

Filed Under Fix, Windows | Leave a Comment

Today I was hit with a 0-day virus – ZBot/Backdoor.Paproxy or whatever antivirus companies call it.

It came as E-mail claiming to be from UPS (You guess now why UPS virus is in quotes) and was a zip file with executable inside. UPS_INVOICE_978172.zip to be exact, but there are several variants.

Usually the common is that they contain as subject line:”[RE] UPS Tracking Number” followed by random number.

Most of the e-mails were detected (as spam) by the antivirus scanner on mail gateway, but some reached end users.

To be honest this one was really good in attracting them (the users) to open it and some did….

This was no pleasant experience. Right away PC rebooted and trojan was installed.

Other problem was that there was only 2 companies who were able to detect it this morning (the number increased to 13 afternoon).

After updated virus definitions from Symantec were installed Backdoor was detected and removed.

Lesson learned: NEVER open executable from attachment.

Here you ca see if your antivirus is up to date with that particular virus.

Another  version…

UPDATE: There are new versions not recognized by Symantec yet. So follow above lesson.

[ERROR] /usr/libexec/mysqld: Incorrect key file for table

Filed Under Fix, Linux | 1 Comment

After I rebooted manually my database server I received following message in mysql log:

[ERROR] /usr/libexec/mysqld: Incorrect key file for table <name of the table>.MYI’; try to repair it

The fix is relatively simple

  1. Go to MySQL console – mysql
  2. Point to correct database – use <database name>
  3. Issue command to repair – repair table <name of the table>
  4. Sit back and wait – it will take some time

Clean your ThinkPad from beginning

Filed Under Fix, Howto, Windows | Leave a Comment

Lenovo is shipping new ThinkPads preinstalled with huge amount of software you do not really need.

This slows the boot process to the levels new computer should not be.

Here is the list of software I removed from T61:

  • All MS Office related (trial) – Later I’ll install the products we have license for
  • SQL server (yes it is installed) related
  • Windows Live toolbar
  • Norton Internet Security – Will replace it with Norton Endpoint Protection

Other option is to reinstall the system from scratch.

Excellent tutorial on how to do it

Tip: Do not connect the system to internet until you are ready to. It starts right away to download and install windows updates and will slow down the machine.

WordPress update…

Filed Under Announcements, Fix | 1 Comment

Upgrade to latest version.

As usual not without problems. This time maintenance plugin blocked the access to the site and I had to unblock it manually. Fortunately I was no the only one to have similar problem and quick search showed the solution.

How to fix Foxmarks:error 400

Filed Under error, Fix | Leave a Comment

Recently I remarked that my Foxmarks do not sync anymore…

After going to Log file I discovered that I have error 400 (unknown error) .

Quick search on Foxmarks site showed me that I’m not the only one.

Automatic fix did not work for me, so I was forced to do manual fix.

Be sure that you have latest version of your bookmarks on the PC you do the fix. Otherwise you may have problems with missing bookmarks.

Virtinstall error

Filed Under error, Fix, Linux | Leave a Comment

When trying to install CentOS 5 in Xen DomU via http I received following error:

“Could not find an installable distribution the install location”

The problem was that instead  pointing to root of folder containing mounted disk images I should point to disk1.

That solved my problem.

ftsata2 driver failed to load

Filed Under Fix, Windows | Leave a Comment

I’ve decided to check the logs on my Compaq system and I discovered following error:

Event Type:    Error
Event Source:    Service Control Manager
Event Category:    None
Event ID:    7026
Date:        16/12/2007
Time:        2:50:16 PM
User:        N/A
Computer:    COMPAQ
Description:
The following boot-start or system-start driver(s) failed to load:
ftsata2

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

It was little bit strange, because I have nvidia s-ata drivers installed, and this driver appear to be from promise. After searching on Internet I came to following solution posted on hp site:

Go to Start->Control Panel->System->Hardware->Device Manager->View->Show Hidden Devices->Non Plug and Play Drivers->ftsata2->Driver->Start up Type = Demand

Shortcut: just press Win key + Pause/Break -> and continue from Hardware

ThreatFire + Wget(windows) = False Positive

Filed Under error, Fix, Windows | Leave a Comment

New(old) PcTools tool detected my wget.exe as keylogger. After submitting the issue to tech support they concluded(surprisingly fast for free product) that most probably it is false positive and after further study they will update their rules.

For now just add wget.exe to safe processes.
