01 Security

Is port 1498 dangerous?

We have no specific security note for port 1498. Its risk depends on the program actually listening on it. General advice for databases & caches services:

  • Bind the service to localhost or a private network, never to a public address.
  • Enable authentication, use per-application accounts and require TLS.
  • Watch for exposed Docker ports: publish them on 127.0.0.1 only.

03 Check it

Which program uses port 1498, and is it reachable?

Linux

sudo ss -ltnup 'sport = :1498'      # process listening on 1498
sudo lsof -nP -i :1498

macOS

sudo lsof -nP -i :1498

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 1498 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 1498
netstat -ano | findstr :1498

From another machine

nmap -p 1498 -sV <host>
sudo nmap -sU -p 1498 <host>
nc -zv <host> 1498

Block it in the firewall

sudo ufw deny 1498/tcp                                         # Linux (ufw)

04 FAQ
What is port 1498 used for?

Port 1498 is assigned by IANA to sybase-sqlany (Sybase SQL Any).

Is port 1498 TCP or UDP?

Port 1498 is registered for TCP and UDP.

Is it safe to open port 1498?

It depends on the program that listens on it. Open it only for a service you know and only to the networks that need it. Bind the service to localhost or a private network, never to a public address.

How do I check if port 1498 is open?

On Linux run "ss -ltnup 'sport = :1498'", on macOS "lsof -nP -i :1498", and on Windows "netstat -ano | findstr :1498" to see the local process. From another machine, "nmap -p 1498 <host>" shows whether it is reachable.
