launchd listening on port 4444 the lsof command tells me launchd is listening on port 4444:

$ sudo lsof -i tcp:4444

COMMAND PID USER   FD   TYPE           DEVICE SIZE/OFF NODE NAME
launchd   1 root   32u  IPv4 0xfe4e7e9bb5c1a5      0t0  TCP localhost:krb524 (LISTEN)
launchd   1 root   46u  IPv4 0xfe4e7e9bb5c1a5      0t0  TCP localhost:krb524 (LISTEN)


I'm trying to set up a Selenium (https://www.seleniumhq.org/) Server whose default port is 4444 - I realise I could change Selenium's port, but I don't recall having this clash on Macs previously (I guess prior to Tiger)

Is it possible/viable to have launchd run on a different port?

EDIT:
I found the following info by searching which plist files refer to port 4444 - it shows that it's part of the Server configuration.  The Wiki feature of Server is currently turned OFF.  Is it safe to edit this file to change the port setting?

I suggesting noting which files you change and exactly how you change them, as updates to the Server app will very likely undo all of the changes you made. You may even want to make a shell script that looks for these files and automatically changes them at boot time, every time. I have to do something similar so my brew-installed apache doesn't get disrupted by the system's apache.
