Port 601Reliable Syslog

Reliable Syslog transports log messages between clients and collectors, typically over a persistent TCP connection.

Technical Details

what runs on :601

The registry assigns this service to both TCP and UDP, although the standardized Reliable Syslog deployment uses a persistent TCP connection with BEEP session negotiation and framed messages. BEEP provides channel management and message framing around syslog records; encryption is not enabled by default. Traditional UDP syslog commonly uses port 514, while Syslog over TLS uses TCP port 6514.

Security Information

3/ 10caution

worth attention. how exposed you are depends on configuration — don't leave it reachable from the internet without a reason.

network services averages 3.2 across 870 ports — this one sits 0.2 below.

tcp · udp

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

security overview

Reliable Syslog is normally cleartext unless protected by an additional TLS tunnel or equivalent control, so exposed traffic can disclose log contents and permit message spoofing or injection. Internet-facing collectors may also be abused for log flooding and resource exhaustion; restrict access to known senders and prefer port 6514 for encrypted transport.

usage: This port is used for Reliable Syslog, most notably the BEEP-based transport defined by RFC 3195, between logging agents and collectors. It is much less common than UDP syslog on port 514 or Syslog over TLS on port 6514.
