Bring back option to configure target SNMP port

[amotl]

Hi,

A custom port can be specified by using -p. The default value is 161.

I just discovered that the refactoring coming from #4/#19 dropped that feature to specify the target SNMP port number (#2), so we will have to bring it back when there is demand.

Also, after integrating #21, the Icinga configuration snippets will provide access to almost all parameters this program has to offer. However, the -p option is still missing there. Also depending on community demand, this can be added every time.

With kind regards,
Andreas.

Good catch, I would like to have this functionality back in the script (still with default so that one does not have to use it). Adding it to the example files is a good idea, too 👍🏻

I will try to take care about it within one of the next iterations.

Current README also lists setting the port as an option. Should remove the part from the README in the meantime to not confuse new users?

As #31 now got merged i would like to publish a new release. But as the option to configure a target port is still a regression it would be a major version. So i am drafting a feature version bump as a pre release and release "normal" one as soon as this regression is solved.

EDIT: published pre-release v0.4.0-beta.1

Dear Frederic,

I will re-add this option in the course of the next iterations. That's why I wanted to add #39 ff. beforehand.

In the meanwhile, as I found out just yesterday, everyone can use a composite host syntax like appliance.example.net:1161, just adding the port number to the host name. Easy SNMP accepts that as well.

With kind regards,
Andreas.

Braindump (for future me or others): The corresponding option for the easysnmp Session should be remote_port.

I added the missing port definition to easysnmp.Session in #46
