Cave 5

Supongamos que queremos migrar un ap de un controller a otra instalación nueva de un controller. Usamos el comando set-inform http//<controller ip>:8080/inform. Particularmente estoy migrando el controlador a un contenedor docker. No se si tiene que ver o no. Hay veces que el comando set-inform no aparece en bash despues de conectarnos por ssh al ap con ubnt@ubnt. Encontré este comando en un foro de home assistant que literalmente me solucionó el problema. ssh admin@<your_unifi_ap_ip> "/usr/bin/mca-cli-op set-inform http://<your_unifi_controller_ip>/inform ; exit" l ink ¡Gracias  JeremiahCornelius !

Just for Linux Remote host to localhost: username@remotehost.com:file /local_directory/  From localhost to Remote host scp file username@remotehost.com:/remote_directory/ 

Locally add the following to ~/.ssh/config ServerAliveInterval 120 # null packet every 120 seconds On the server side add the following: ClientAliveInterval 120 # null packet every 120 seconds ClientAliveCountMax 720 # 24hs Done!

To search all the ips that were banned we enter interactive mode: $ fail2ban-client -i Then we check a jail status, for example sshd : > status sshd the output: Status for the jail: sshd |- Filter |  |- Currently failed: 0 |  |- Total failed: 27 |  `- File list: /var/log/auth.log `- Actions    |- Currently banned: 37    |- Total banned: 38    `- Banned IP list: <a big list of banned ips> So, if we want to unban a particular ip address, let's say X Then, we execute: > set ssh unbanip (within interactive mode) Lastly, if you want to execute it directly from command line: $ fail2ban-client get <JAIL> actionunban <IP-ADDRESS> That's all.

Just run: cat / dev / null > ~/. bash_history && history - c && exit

Just run the following command: $ chmod -R -N mydoc

The easiest way to install memcached is to use homebrew package installer: $ brew install memcached This locates memcached in /usr/local/opt/memcached/bin/ Starting memcached (by default at port 11211 or with -p port_number): $ memcached -p 9000 To have launchd start memcached now and restart at login: $ brew services start memcached To change the default ram size (64mb) used by memcached use -m option: $ memcached -m 128  -p 9000 Lastly, run memcached as a daemon with -d: $ memcached -d -p 9000

Command CheatSheet h(elp) : Without argument, print the list of available commands. With a command name as argument, print help about that command. w(here) : Print a stack trace, with the most recent frame at the bottom. An arrow indicates the “current frame”, which determines the context of most commands. d(own) : Move the current frame one level down in the stack trace (to a newer frame). u(p) : Move the current frame one level up in the stack trace (to an older frame). b(reak) : [ ([filename:]lineno | function) [, condition] ] With a filename:line number argument, set a break there. If filename is omitted, use the current file. With a function name, set a break at the first executable line of that function. Without argument, list all breaks. Each breakpoint is assigned a number to which all the other breakpoint commands refer. The condition argument, if present, is a string which must evaluate to true in order for the breakpoint to be honored. tbreak : [ ([filenam...
