GnuTLS and GLib, Part 2: Socket layer

A description of how to let GnuTLS use a GSocket as transport layer.

First steps with libnl

How to find out the IP addresses associated with an interface via libnl, and some GLib stuff I learned in the process.

SCTP sockets can operate in two modes: SOCK_SEQPACKET or SOCK_STREAM. When migrating my server from UDP to SCTP, I initially used the sequential packet mode. However, changing to stream mode offered me two significant advantages: I use threads to process data from different clients. With sequential packet mode, the callback for new data has toContinue reading “SCTP socket in stream mode”

Using SCTP in GLib

A while ago, I wrote about using a UDP socket as event source in GLib. Now, I’m migrating my program to SCTP. The main reason is that SCTP provides reliability for sequential messages, but some of the advanced features might become useful later. Surprisingly few changes were necessary in my program: Create the socket withContinue reading “Using SCTP in GLib”

Using a UDP socket as event source in GLib main loop

I found out how to get an event in the GLib main loop when a UDP socket receives data (with code snippets).
