RAR support
Since Dune does not handle talking to llink (over HTTP) in any form [1], I found myself missing the unrar streaming support that llink provides. So I started considering a solution for this problem. I have assumed that Dune developers are not approachable, nor particularly interested in helping someone on the outside, so it would have to be a solution I could do myself.
I started on the idea of using LD_PRELOAD to point to my glue code, which intercepts the calls open64/read/lseek/close/opendir/readdir64/closedir/lstat64/stat64.
I have now reached a point where this appears to work. To test the libc replacement library, assuming you already have telnet access, download the binary and setup like:
# cd /tmp # wget http://lundman.net/ftp/librarcy/librarcy.so.1.0.1 # wget http://lundman.net/ftp/librarcy/unrar # killall shell root # env LD_PRELOAD=/tmp/librarcy.so.1.0.1 /etc/init.d/S99local start
If someone has a better way to start "root" again than to run the whole init.d script, let me know.
You can watch the content of "/tmp/librarcy.log" for signs of success.
[1] I note the SMP Libraries handles HTTP:// URLs internally, so possible could exploit this to play remote media.
