Re: isectpd & isecespd process restart remotelly from ePO ?
From my own experience I generally access a server through SSH, then copy / paste the command-line value's you mentioned.
Something my team has started doing more is working with the ePO API, I would bet there might be some useful methods which may be of help. Unfortunately just as you have, I've had to make those same calls manually. The Linux Support team at my office has used Ansible to do a mass / scripted install of products and I'm sure it might can be adjusted for an agent wake-up call. Haven't tested it myself.
Hopefully we can get some more insight on this, I'm curious to see how others administrate their Linux environments.
