The attached patch makes xenconsole send and receive console messages over a remote connection, instead of via stdin/stdout - if given the --remote switch. It is useful for proxy''ing real console message or other protocol messages (such as gdb) between dom0 and a remote host. We''re currently using it for proxying gdb between gdbstub in a partition that talks gdb over the console

Hi, One feature missing from rsync, and requested on this list before, is on-the-fly conversion of filename character encoding. For example, I often need to sync files having Hebrew filenames from a UTF-8 system (Linux) to an ISO8859-8 system (Cygwin on Windows 2000 using the non-Unicode Win32 interface). Other circumstances surely abound. Attached is a patch against rsync 2.6.2 that adds an

Improve readability of commandrvf() by replacing bare int values for file descriptors with their symbolic names STD{IN,OUT,ERR}_FILENO. Also add PIPE_READ and PIPE_WRITE for referencing relevant ends of a pipe. --- daemon/guestfsd.c | 79 +++++++++++++++++++++++++++++-------------------------- 1 file changed, 42 insertions(+), 37 deletions(-) diff --git a/daemon/guestfsd.c b/daemon/guestfsd.c

select() has a maximum value for the FDs it can monitor, and since the libguestfs library can be used in other applications, this limit may be hit by users in case lots of FDs are opened. As solution, switch to poll(): it has a slightly better interface to check what changed and for which FD, and it does not have a limit in the value of the FDs monitored. poll() is supported on the platforms we

Hi, As using a blocking socket for a virtio device channel leads to be blocked if nobody has opened the corresponding /dev/virtio-ports within the Guest , I tried to use a non-blocking socket and to check whether the socket is writeable via FD_ISSET(). I'm wondering why a virtio device channel is always seen as writeable by the Host even if nobody has opened the corresponding

on systems that has separate IPv4/v6 socket layer (i.e. IPv4 packet does not get routed to AF_INET6 socket) rsync --daemon would accept IPv6 sessions only. open_socket_in() tries to deal with the situation, but it was not enough. here's the patch. (it is required on all *BSDs to accept both IPv4 and IPv6 connections with --daemon mode) itojun --- ? configure.lineno ? lib/dummy

The original implementation utilies select(). In Linux select() typically supports up to 1024 file descriptors. This can be a problem when user tries to boot up many guests. Switching to poll() has minimum impact on existing code and has better scalibility. Up to 8192 file descriptors are supported in the current implementation.

Hello all, This is a problem and patch reported to Red Hat Bugzilla by Jonathan Kamens <jik at kamens.brookline.ma.us>. I'm just acting as a relay :-) jik has experienced some weird crashes relating to window size changes or some similar activity. These are rather hard to trace. Problem was fixed by patching clientloop, where fd_set structures appear to be improperly zeroed (bytes vs

Hello, I use hosts that are dual stack configured (IPv4 and IPv6) and it happens that connectivity through one or the other is broken and timeouts. In these case connection to the SSH server can take quite some time as ssh waits for the first address to timeout before trying the next. So I gave a stab at implementing RFC 8305. This patch implements part of it in sshconnect.c. * It does not do
