Why does i3status need to listen for udp connections?

Wed, 10 Dec 2014 14:49:44 +0000

I have used sockstat to check my opened ports and services which were using them and I have noticed i3status is listening for udp connections. Could the reason for doing that be explained?

I does not do so on my machine, at least `sockstat` does not show anything. Could you please add the relevant output of `sockstat`? Also, a bit of information about your system could help: which distribution, version of *i3* and where from did you get it?

Hi, In my machine (FreeBSD 10.1-RELEASE amd64) there is a listening socket: Output of sockstat:

  $ sockstat -4 | grep i3status

    user i3status   966   3  udp4   *:*                   *:*

and the output of fstat (lsof equivalent):

  
 $ fstat -n -p 966 | grep internet

   user i3status     966    3* internet dgram udp xxxxxxxxxxxxxxxxx

PS: The **xxxxxxxxxxxxxxxxx** represents the HW address of the network card.

i3status does not open a listening socket: sudo netstat -np | grep i3status | wc -l 0 However, it indeed creates a UDP socket: $ sudo lsof -n -p $(pidof i3status) | grep sock i3status 26396 michael 3u sock 0,7 0t0 268864 protocol: UDP The places in the code where sockets are created are http://code.stapelberg.de/git/i3status/tree/src/print_ipv6_addr.c?id=3818dabcebea7f98e3dfdfbe5be42374bb60cf88#n24 and http://code.stapelberg.de/git/i3status/tree/i3status.c?id=3818dabcebea7f98e3dfdfbe5be42374bb60cf88#n542 (which is used in http://code.stapelberg.de/git/i3status/tree/src/print_eth_info.c?id=3818dabcebea7f98e3dfdfbe5be42374bb60cf88#n35) But as I said, those are not listening sockets, so it shouldn’t pose a security problem.
