Technical Details

what runs on :3112

KSysGuard's remote daemon, ksysguardd, normally communicates over TCP port 3112 using a line-oriented text protocol for requests and replies about system sensors and processes. Direct TCP mode is not encrypted; remote setups can instead start the daemon through SSH. IANA lists both TCP and UDP, but the usual KSysGuard service is TCP-based.

Security Information

6/ 10risk

treat as sensitive. widely scanned and regularly exploited when reachable — restrict it to known sources.

remote access averages 3.7 across 194 ports — this one sits 2.3 above.

tcp · udp

udp is connectionless — source addresses are trivially spoofed and it is a reflection favourite

security overview

A directly exposed listener can reveal system metrics and process information, and may allow process actions within the daemon's privileges. Avoid exposing it to the public internet; use SSH-based access or restrict direct connections to trusted hosts. Traffic in direct mode is not encrypted.
