• My cousin leaked my public ip address to someone

  They already had your IP. The whole internet (IPv4 adress space) can be scanned in less than one hour (see: https://zmap.io. Source: over 1 year ago

• The internet is a global village, not a metropolis

  The numbers above demonstrate that it is theoretically possible to mass scan the entire internet. Effective free-to-use tools can be used to perform mass scans, converting this academic opportunity into practice. ZMap, Masscan, and others promise to scan the entire public IPv4 address space in some ten minutes or so on a typical desktop computer with a gigabit Ethernet connection. Researchers proved that the time... - Source: dev.to / about 2 years ago

• Python Port Scanner: Faster than Nmap.

  Zmap (zmap.io) is probably the fastest port scanner. But afaik it's main usage is to scan 1 port on the whole internet instead of all ports on one IP (but you can, too). Source: over 2 years ago

• Awesome Penetration Testing

• Cisco switch backup/restore?

  A decade ago I worked for a shop that needed to routinely back up 100+ cisco switches and routers and refused to pay for solarwinds. I setup a light weight freebsd vm to run this open source software: https://shrubbery.net/rancid/ (Rancid: Really Awesome New Cisco config Differ) and set it to scrape all the equipment every 12 errors.

• Version control for network configs

  Anyways Rancid does support cvs, svn, and git. Though I have only used it with cvs. Basically what it does, is checks out the configuration, downloads the configuration with other information about the state of the device, commits the configurations(which only changed ones will be in the latest check-ins, and then it can send an email of the changes.

• Management Software for Cisco Devices?

  RANCID - Really Awesome New Cisco confIg Differ monitors a router's (or more generally a device's) configuration, including software and hardware (cards, serial numbers, etc) and uses CVS (Concurrent Version System), Subversion or Git to maintain history of changes. Source: about 2 years ago

• What all are you doing with Ansible?

  If you want to use this as an opportunity to learn Ansible, or you don't want to add another tool to the stack, this is a fine use case. Otherwise, I would consider using either RANCID or Oxidized for configuration backup. Source: about 2 years ago

• Starting with python at 30

  Before I knew about RANCiD (https://shrubbery.net/rancid), I wrote my own Perl application to telnet into a Foundry Networks switch and TFTP its configuration to my computer so I could back it up. At a future employer, I rewrote another coworkers Perl application that collected SNMP values from devices and did stuff with it (forget what all I did then). Source: over 2 years ago
