When we are managing a remote system, we need a user that we can login with to perform this function, and we DO NOT want to use the root password as is traditional in a basic proxmox installation. 

First we need to install some prerequisites that we need to be able to function correctly: 

apt install -y sudo net-tools iotop sysstat iftop btop htop traceroute mtr lsof strace lshw

The default username is gensupport, so it will need adding to each node as follows: 

adduser --gecos "GENSupport,,," gensupport

** SELECT A STRONG PASSWORD **

usermod -aG sudo gensupport

Now we'll add the role to proxmox

pveum role add GEN --privs "Datastore.Allocate,Datastore.AllocateSpace,Datastore.AllocateTemplate,Datastore.Audit,Group.Allocate,Mapping.Audit,Mapping.Modify,Mapping.Use,Permissions.Modify,Pool.Allocate,Pool.Audit,Realm.Allocate,Realm.AllocateUser,SDN.Allocate,SDN.Audit,SDN.Use,Sys.AccessNetwork,Sys.Audit,Sys.Console,Sys.Incoming,Sys.Modify,Sys.PowerMgmt,Sys.Syslog,User.Modify,VM.Allocate,VM.Audit,VM.Backup,VM.Clone,VM.Config.CDROM,VM.Config.CPU,VM.Config.Cloudinit,VM.Config.Disk,VM.Config.HWType,VM.Config.Memory,VM.Config.Network,VM.Config.Options,VM.Console,VM.Migrate,VM.Monitor,VM.PowerMgmt,VM.Snapshot,VM.Snapshot.Rollback"
pveum user add gensupport@pam
pveum aclmod / --roles GEN --users gensupport@pam

This concludes the setup for a PAM user on proxmox for GEN HelpDesk use. Be sure to communicate the strong password you selected above to the HelpDesk securely and we recommend this is done through your Account Manager.
