Android Question Receiving data on Syslog port 514

[janderkan]

Trying to interface to a system that sends log messages on port 514 using UDP.
Is there any way to open UDP port 514 for listening.

Android doesn't allow you to open port numbers smaller than 1024.

Does that mean you can't send from port 514? I need to send a message to a syslog server from an app @ 192.168.3.221 port 514.

I could tell them to change the port I guess.

No. It means that you cannot listen to a port number lower than 1024.

Ok, I tried sending packets to port 514 and it failed to compile or run.
I will try again and post the error here.

 

[merlin2049er]

Ok, it basically says 'bind failed' (Permission denied). I guess it can't bind to that port unless the Android OS has been rooted.

Can you post the relevant code? There is no problem with connecting to ports lower than 1024 (remember that the most used port is port 80 which is the standard http port).

Ok. I think the problem is, I was initalizing the port as 514 Instead of 0.
