Not
just a different version, but it appears to be a different codebase.
Debian's netcat doesn't support the (very useful) -U option, so this
code fails in src/remote_internal.c:
cmd_argv[j++] = strdup (command);
//.....
cmd_argv[j++] = strdup (server);
cmd_argv[j++] = strdup (netcat ? netcat : "nc");
cmd_argv[j++] = strdup ("-U");
cmd_argv[j++] = strdup (sockname ? sockname :
LIBVIRTD_PRIV_UNIX_SOCKET);
cmd_argv[j++] = 0;
As a result of this remote-over-ssh fails on Debian. I'm not completely
sure how to solve this at the moment. If anyone has any ideas ...
Since the remote system has to have the libvirt daemon installed already,
we could simply ship a mini 'nc' program of our own - libvirtd-cat ? The
main problem with this would be getting dealing with back-compat. Should
the client try 'nc' first, or ty 'libvirtd-cat' first. Or we could see
if Debian netcat maintainer is interested in a patch to add '-U' support
to their version
