[Putty] How to Increase Scroll Log Buffer for Default Config Putty

Posted on by

Everytime you open Putty with default config.
Default buffer window : 200 raw only
Tracking the history of Putty Activities is not possible as line over 200 will be override.

For me it’s really important to have at least 32000 raw buffer window.
Even you can set 50000

Here how to change
a. Right click and change setting
b. Click Window edit value to 32000 for e.g on line scrollback
c. Click Session
d. Just click default setting
e. Click Save

There you buddy !

[Recommendation] Use Different Block IP for Name Server – DNS (Primary and Secondary) Mail Exchange – MX (Primary and Secondary)

Posted on by

Use Different IP Blocks for Your Primary and Secondary Server (DNS and MX)
Not in the same Class C at least
Purpose :

- Avoiding a Totally DNS Blocking if Third parties filtered your /24
- Avoiding a Totally Mail Blocking if Third parties filtered your /24
- Avoiding Unreachable DNS Primary/Secondary if one BGP path problem
Impact : Timed Out Domain Query and rest Impact of unavailable domain
- Avoiding Unreachable MX Primary/Secondary if one BGP path problem
Impact : Bounched Mail to Sender

Unless you have only /24 :) from a RIR/LIR

[Recommendation] Use Domain and Different Domain for Server POP, IMAP and SMTP

Posted on by

Use Domain for your POP, IMAP and SMTP
Purpose:
- It’s easy to remember domain rather than IP
- It’s easy to change IP address record in DNS if your server had been listed on RBL
or blocked by others for any reason
- There’s no change on user Mail Client Setting
- Using same Domain for POP,SMTP and IMAP in the same mailserver
may not a good choice once you need to move (balance load)
just either SMTP, POP or IMAPto another server (let say the server is overloading).

Use Different Domain for your POP, IMAP and SMTP
Purpose:
- It’s easy to change / move IP Address record in DNS
- It’s easy to move IP from one machines to another machines
and change record without re-socializing the new IP to your customer

[MSOffice 2010] How to Find Hidden PowerPoint Animations in Animation Pane ?

Posted on by

Running Animation for any Icon in a Power Point Presentation would explain more clear about a process to the audience.
Anyway, you might have found that when trying to play the animation you have created..
You see more animation rows on animation pane which you believe that you didn’t even created.

Why this is happened ?

Your master slide already have animation applied.
Go to Master Slide and remove the Animation
So will see now the normal/right number of animation rows.

Sample of what I have in master slide.

Sample of normal slide

Before removing animations in Master slide, I saw there many rows while playing (test) the animation

[Office 2010] Microsoft Office Excel 2010 Not Automatically Calculate the Cell Formula Until File Saved

Posted on by

Last few weeks till today I have a weird thing happened on my XLS cell formula.
I’m running Office 2010 XLS and used to calculate with formula.

Weird thing was : the cell formula not even calculating after I changed some of values on other cell that correlated with the formula. Googling somewhere I found an idea from tech republic which alse experience similar thing but on Excel 2007.

Anyway, it must be same solution but in another how to on Office 2010.
Just go to File and Options, then to Formulas.
The calculation option has to be set to “automatic” to have the cell formula automatic calculating.

Just curious how could I get in to this issue before :) ?
