1. What is this

This is a fork of bashacks by Fernando Mercês, mainly to do some development.

2. Additional Requirements

The additional requirements listed here are Debian/Ubuntu packages. They might be named differently on different distros.

  • passwdqc
  • whois

3. Additional Functions

  • bh_asinfo: Look up AS information in Team Cymru's whois for a given AS. (The string AS is prepended to the argument if it is not included.) Examples:

    tdussa@flattop ~ $ bh_asinfo 32868        
AS      | CC | Registry | Allocated  | AS Name
32868   | US | arin     | 2004-08-10 | FLEX-DATASIDE-AS01, US

    tdussa@flattop ~ $ bh_asinfo AS1  
AS      | CC | Registry | Allocated  | AS Name
1       | US | arin     | 2001-09-20 | LVLT-1, US

  • bh_dwpwd: Generate a diceware password with only letters and digits. Example:

    tdussa@flattop ~ $ bh_dwpwd
ornate7run7rude8mighty6Brine

  • bh_dwpwx: Generate a diceware password, potentially containing special characters as well. Example:

    tdussa@flattop ~ $ bh_dwpwx
Bitch6snap*Dune9Red$humane

  • bh_ip2as: Look up AS information in Team Cymru's whois for a given IP. Example:

    tdussa@flattop ~ $ bh_ip2as 129.13.64.5
AS      | IP               | AS Name
34878   | 129.13.64.5      | KIT Karlsruhe Institute of Technology, DE

  • bh_ip2cymru: Look up all information provided by Team Cymru for a given IP. Example:

    tdussa@flattop ~ $ bh_ip2cymru 129.13.64.5
AS      | IP               | BGP Prefix          | CC | Registry | Allocated  | AS Name
34878   | 129.13.64.5      | 129.13.0.0/16       | DE | ripencc  | 1987-06-29 | KIT Karlsruhe Institute of Technology, DE

  • bh_ip2irt: Look up abuse contact information and the relevant IRT object in whois for a given IP. Example:

    tdussa@flattop ~ $ bh_ip2irt 129.13.64.5
% Abuse contact for '129.13.0.0 - 129.13.255.255' is 'cert@kit.edu'

  • bh_mac2vendor: Takes a MAC address as input and retrieves the associated vendor. Uses your own MAC addresses (as returned by bh_mymac) if no MAC is specified. The last line in the example shows a MAC address with no associated vendor. Examples:

    tdussa@flattop ~ $ bh_mac2vendor
c8:5b:76:12:ab:c5: LCFC(HeFei) Electronics Technology co., ltd
f0:d5:bf:34:cd:5d: Intel Corporate
26:2c:dc:56:ef:73: {"errors":{"detail":"Not Found"}}

    tdussa@flattop ~ $ bh_mac2vendor b8:69:f4:ab:cd:97
b8:69:f4:ab:cd:97: Routerboard.com

  • bh_myip6: Like bh_myip does for IPv4, this function retrieves your externally-used IPv6 address.

  • bh_mymac: Similar to bh_myip or bh_myip6, this function retrieves your local MAC address(es). It optionally takes a network device as argument; if empty, it will query and output the MAC addresses of all local devices. Examples:

    tdussa@flattop ~ $ bh_mymac
c8:5b:76:12:ab:c5
f0:d5:bf:34:cd:5d
26:2c:dc:56:ef:73

    tdussa@flattop ~ $ bh_mymac enp0s31f6
c8:5b:76:12:ab:c5

  • bh_prefix: Prepends all STDOUT and STDERR lines with given prefixes, potentially different ones for STDOUT and STDERR. If the environment variable PREFIX is set, then that is used for STDOUT; if PREFIX2 is set, that is used for STDERR. If neither is set, the first argument is taken and used for both. Beware: This function may cause relative reordering of STDOUT and STDERR output. Examples:

    tdussa@flattop ~ $ bh_prefix "ALLOUT:\t" ssh localhost "echo OK; echo ERROR > /dev/stderr"
ALLOUT:	OK
ALLOUT:	ERROR

    tdussa@flattop ~ $ PREFIX="STDOUT:\t" bh_prefix ssh localhost "echo OK; echo ERROR > /dev/stderr"
STDOUT:	OK
ERROR

    tdussa@flattop ~ $ PREFIX2="STDERR:\t" bh_prefix ssh localhost "echo OK; echo ERROR > /dev/stderr"
OK
STDERR:	ERROR

    tdussa@flattop ~ $ PREFIX="STDOUT:\t" PREFIX2="STDERR:\t" bh_prefix ssh localhost "echo OK; echo ERROR > /dev/stderr" 
STDERR:	ERROR
STDOUT:	OK
