go2host

Presentation

The script allows to present a list of server (from config file) in order to connect in ssh
The script lets you jump quickly to a server.

You can use an argument to filter the given servers list.
If the filter gives you a single result, then automatic ssh connection to this unique host (see example Example 3).

Requirement

• SSH accessibility to your servers
• sshpass if you want to use login/password for the connection
• Need a conf file, it must be in the format below (id,ip,descr,login,password are optionals) :  

(id;)hostname;(ip;descr;login;password)
100;host1;(10.0.0.1;description_with_no_space;root;supersecurepassword)
101;host2;(10.8.0.5;description_with_no_space;newlogin;supersecurepassword)

ip is optionnal but hostname is compulsory, you can add the ip info that will be used preferably against the hostname

• Need to change inside the script go2host.pl about 2 variables :
  • $conf => your conf file with hostnames and @ip (respect specific file format)
  • $sshpass => path to the binary sshpass

Tested with

• Perl v5.22.1 and v5.16.3

Todo

• display information in right columns (instead of tabulations)
• possible to filter during the question : Choose an id (or filter)
• row id optional => the script provides an id that starts at 1.
• better managemnt of the first row of column names (not show when filter)
• if the filter gives you a single result, automatic ssh connection to this unique host
• add option --ping (tell if hostname is alive) ?

Utilization

Example1 (no filter) :

./go2host.pl 
id       hostname
101      host1
102      host2
103      host3
104      host4
401      web1
402      web2
403      web3
404      web4
Type id (or filter) : 101
You are redirected to :
Last login: Thu Oct  5 11:14:15 2017
[root@host1 ~]# 

Example2 (with filter) :

./go2host.pl web or ./go2host.pl ^4
id       hostname
401      web1
402      web2
403      web3
404      web4
Type id (or filter) : 404
You are redirected to :
Last login: Thu Oct  5 11:14:15 2017
[root@web4 ~]# 

Example3 (with filter for a single server) :

./go2host.pl 404 or ./go2host.pl web4
id       hostname
404      web4
