Hi,
When running RStudio Desktop on Linux Ubuntu it opens port.
I assume it is for communication between IDE and R processes.
lsof -n -P | grep LISTEN
rsession 7114 jan 14u IPv4 60661 0t0 TCP 127.0.0.1:16132 (LISTEN)
rsession 7114 7116 jan 14u IPv4 60661 0t0 TCP 127.0.0.1:16132 (LISTEN)
rsession 7114 7117 jan 14u IPv4 60661 0t0 TCP 127.0.0.1:16132 (LISTEN)
rsession 7114 7118 jan 14u IPv4 60661 0t0 TCP 127.0.0.1:16132 (LISTEN)
rsession 7114 7131 jan 14u IPv4 60661 0t0 TCP 127.0.0.1:16132 (LISTEN)
rsession 7114 7132 jan 14u IPv4 60661 0t0 TCP 127.0.0.1:16132 (LISTEN)
In Ubuntu OS firewall is disabled by default.
Any there any extra risks added by those open ports? I sometimes use public unprotected networks in cafe or airport.
Is there anything I can do to mitigate this risk (if any)? other than enabling firewall. For example switching RStudio to single R process execution model?
