Some commands I commonly use

    df -h --total
    or
    System monitor > Filesystems tab
  2. Directory or space with their usage:
    du -a -d 1 /home/ | sort -n -r | head -n 5
  3. Find folder with specific name
    find /path/to/look/up -type d -name "folder name"
  4. Linux version:
    lsb_release -a
  5. Cisco IOS doesn’t accept ssh:
    ssh -oKexAlgorithms=+diffie-hellman-group1-sha1 username@target-hostname/IP
  6. Find specific word: (source: link)
    grep -rnw '/path/to/somewhere/' -e 'pattern'
    -r
    or -R is recursive,
    -n is line number, and

Say you are a fine Network Engineer, in a situation where you were asked work together with Server team to change the IP address of particular servers. During assessment, you found where the IP connected to which switchport by ARP and MAC address checking.

During execution (which already gone through…

What for: use this command in the interface configuration to prohibit broadcast packet forwarded to network subnet which is different from source packet.

Example:
- Source: 12.12.12.2/24
- Destination: 13.13.13.255/24 → broadcast address

Topology:

Configuration:

R1(config)#interface fa0/1
R1(config-if)#ip directed-broadcast

default: no ip directed-broadcast

Testing:

R2 is doing ping to 13.13.13.255

It always, always happens to me everytime I read either books or articles. Jump from one thing to another, just because I don’t understand about something, or maybe have been red about it and forgot again. Just now is the example. I started to read book of Nidhal Guessoum, where it tells about Averrous (Ibn Rushd). Then there’s a part mentioning about witch-hunt during Middle Ages. Jumped to witch-hunt article in Wikipedia. Not a long read the article, there’s Thirty-Years of War article, then there’s Hapsburg-French rivalry article, and the list still continue.

I think that’s why I rarely finished reading an article in short time.

I stared at cloud which moving slowly in the blue skies. I couldn’t help myself to sometimes felt asleep for minute or two. When awaked, I saw the cloud already change to blackish cloud, gloomy one. Stared again, and felt asleep again, woked up again, and change again to clearer cloud than before. Amusing scene.

Cloud doesn’t change I realized. It only moved and changed colour. Cloud never changed to rain, rainbow, nor sky. Each of them perform different roles. We could say, they are professional.

I don’t know how to share my minds
