Today, I would be explaining the way to maintain the DB with data persistent when connecting to docker.

System Status

Postgresql DB container is in Docker
Windows 10 PC
Linux containers

Issue

Whenever I restart docker/PC the database wiped off due to container is stopped.

Solution

Create a docker volume

Capture localhost (127.0.0.1) system packets using RawCap

Hi friends,

Today I am going to share the knowledge of capturing network packets in local system i.e. localhost.

Using RawCap utility, you can capture the loopback adapter packets which are our localhost packets.

Procedure

Download the RawCap.exe from Netresec website url
http://www.netresec.com/?page=RawCap
Once you download it
Open command prompt with administrator privileges
You have the following options while running the RawCap.exe

Syntax

RawCap.exe
-c <-> Stop capturing after the specified packet count reached
-f <-> Flush each packet without buffering
-s <-> Stop capturing after the specified time limit

Example 1:
RawCap.exe 127.0.0.1 dump.pcap
Note: Ctrl + C to stop the capturing

Example 2:
RawCap.exe -c 1000 127.0.0.1 dump.pcap
After 1000 packets, the capturing will stop

Convert windows drive or disk file system from FAT32 to NTFS without losing data

Hi all,

I had a problem with my external hard disk when copying some 25GB file.

I had troubleshoot the problem and understand that, my hard disk file system is FAT32, which can only copy max 4GB single file size

 

I was thinking without losing my data, how can I change the file system, so that, I copy more than 4GB sized single files

Then I come across the following commands in Windows

1) chkdsk : Check disk

2) convert : Convert disk file system

 

chkdsk command

Syntax

cmd> chkdsk volume_letter: [options]

Example

Checks for disk errors and fix it

cmd> chkdsk I: /f

 

convert command

Syntax

cmd> convert volume_letter: FS:NTFS [options]

Example

Convert volume from FAT to NTFS in verbose

cmd> convert I: /FS:NTFS /V

 

Possible Errors with solutions

Insufficient Memory

Reason

Nearly 4 GB files in existing FAT32 system

Solution

Move the files to local drive, do chkdsk and then convert

Firefox 7 Preferences Files has been changed

Hi everyone,

The developers who want to customise their latest Firefox 7, there is no pref.js (preferences file, which we used to configure the firefox) and user.js (user preferences file).

We can use one and only one preferences file named syspref.js to configure the default firefox.

In Ubuntu it is located under /usr/lib/firefox-7.0.x/defaults/pref/syspref.js

Here we can configure our default homepage and proxies etc.

We can do the same by typing about:config in the browser address bar.

Update your browser and set up according to your convenience.

Please reach me @ psrdotcom@gmail.com @ for queries.
