01 Security

Is port 2262 dangerous?

We have no specific security note for port 2262. Its risk depends on the program actually listening on it. General advice for file transfer & sharing services:

  • Prefer encrypted protocols (SFTP, FTPS, SMB 3 with encryption).
  • Disable anonymous access and restrict shares or exports to known hosts.
  • Never publish file sharing protocols to the Internet.

03 Check it

Which program uses port 2262, and is it reachable?

Linux

sudo ss -ltnup 'sport = :2262'      # process listening on 2262
sudo lsof -nP -i :2262

macOS

sudo lsof -nP -i :2262

Windows (PowerShell)

Get-NetTCPConnection -LocalPort 2262 -State Listen | Select LocalAddress, OwningProcess
Get-NetUDPEndpoint -LocalPort 2262
netstat -ano | findstr :2262

From another machine

nmap -p 2262 -sV <host>
sudo nmap -sU -p 2262 <host>
nc -zv <host> 2262

Block it in the firewall

sudo ufw deny 2262/tcp                                         # Linux (ufw)
New-NetFirewallRule -DisplayName "Block 2262" -Direction Inbound -LocalPort 2262 -Protocol TCP -Action Block  # Windows
04 FAQ
What is port 2262 used for?

Port 2262 is assigned by IANA to comotionback (CoMotion Backup Server).

Is port 2262 TCP or UDP?

Port 2262 is registered for TCP and UDP.

Is it safe to open port 2262?

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. Prefer encrypted protocols (SFTP, FTPS, SMB 3 with encryption).

How do I check if port 2262 is open?

On Linux run "ss -ltnup 'sport = :2262'", on macOS "lsof -nP -i :2262", and on Windows "netstat -ano | findstr :2262" to see the local process. From another machine, "nmap -p 2262 <host>" shows whether it is reachable.
