Management

Fabric - Python library

https://github.com/fabric/fabric Fabric is a high level Python (2.7, 3.4+) library designed to execute shell commands remotely over SSH, yielding useful Python objects in return.

Fabric (1.x and earlier) was a hybrid project implementing two feature sets: task execution (organization of task functions, execution of them via CLI, and local shell commands) and high level SSH actions (organization of servers/hosts, remote shell commands, and file transfer).

invoke - Python library

https://github.com/pyinvoke/invoke When planning Fabric 2.x, having the “local” feature set as a standalone library made sense, and it seemed plausible to design the SSH component as a separate layer above. Thus, Invoke was created to focus exclusively on local and abstract concerns, leaving Fabric 2.x concerned only with servers and network commands.

Ansible - Python

https://github.com/ansible/ansible using SSH, with no agents to install on remote systems.

docker run -d -p 8089:8080 -p 50000:50000 jenkins/jenkins:lts
docker exec jenkins cat /var/jenkins_home/secrets/initialAdminPassword
docker run jenkins/jnlp-slave -url http://jenkins-server:port <secret> <agent name>

https://wiki.jenkins.io/pages/viewpage.action?pageId=75893612

Open a browser on the slave machine and go to the Jenkins master server url (http://yourjenkinsmaster:8080).
Go to Manage Jenkins > Manage Nodes, Click on the newly created slave machine. You will need to login as someone that has the "Connect" Slave permission if you have configured global security.
Click on the Launch button to launch agent from browser on slave.

SNMP

https://en.wikipedia.org/wiki/Simple_Network_Management_Protocol

v1: Authentication of clients is performed only by a "community string", in effect a type of password, which is transmitted in cleartext. v2c comprises SNMPv2 without the controversial new SNMP v2 security model, using instead the simple community-based security scheme of SNMPv1. incompatible with SNMPv1 in two key areas: message formats and protocol operations. v2u: greater security than SNMPv1, but without incurring the high complexity of SNMPv2. v3 primarily added security and remote configuration enhancements to SNMP.

the agent connects to the server on port 162 port 161 on the agent side is used for queries
