Copy various Unix socket handling techniques from nbdkit's nbd plugin: Silently truncating a socket name rather than issuing an error message can confuse users. No need to do an explicit memset if the compiler does it for us via an initializer. No need to use strncpy() which does wasted effort on short names, when we can use memcpy() given that we already checked length in order to detect

Hi, I' trying to read datas sent by my KVM host within the Guest. Host send these datas trough a channel UNIX type , by using AF_UNIX socket stuff. If i try to retrive the datas by using such type of thing in the Guest : #define NAME "/dev/virtio-ports/agent" sock = socket(AF_UNIX, SOCK_STREAM, 0); 12 if (sock < 0) { 13 perror("opening stream socket");

Just forwarding this changelog from yesterday. xcs now uses Unix domain sockets in unstable. This was a hot thread a couple months back with strong opinions on both sides and no clear resolution on the list, so I thought some people might like to know the developers'' resolution. This should be good news for those seeking tighter dom0''s, particularly those who

The attached patch should solve the following problem: ssh-agent creates a temporary directory under /tmp with '600' permissions. The actual socket file is created in that dir using the default umask. That's no problem in U*X systems since nobody but the owner of the directory can read the socket file. Unfortunately, Windows has a user privilege called "Bypass traverse

This approach is more complex than I'd like, but it works even on Solaris, which has neither credential passing nor permissions on the socket itself. --- src/control.c | 82 +++++++++++++++++++++++++++++++++++++++----------- src/control_common.h | 1 + src/tincctl.c | 67 +++++++++++++++++++++++++++++++++-------- src/tincd.c | 2 +- 4 files changed, 120

Hi there, I already asked the list about the problems with sockets on FreeBSD (see here: http://www.mail-archive.com/rsync@lists.samba.org/msg08121.html). I adopted Andrew Flury's patch to the recent CVS version of rsync: Index: rsync.h =================================================================== RCS file: /cvsroot/rsync/rsync.h,v retrieving revision 1.155 diff -r1.155 rsync.h

The idea behind this change is to add support for different "ssh-agents" being able to run at the same time. It does not change the current behaviour of the ssh-agent (which will set SSH_AUTH_SOCK just for itself). Neither does it change the behaviour of SSH_AGENT_PID (which still supports only one pid). The new implementation will go through the list of sockets (which are separated by a

There is a race in the setup of the ControlMaster socket in auto mode, as illustrated by the following command line: ssh -oControlMaster=auto -oControlPath=sock localhost 'sleep 1; echo 1' & ssh -oControlMaster=auto -oControlPath=sock localhost 'sleep 2; echo 2' & Both of the commands will try to start up as a control client, find that sock does not exist, and switch into

The following patch (adapted to rsync 2.5.5 from the one posted in Dec. 2000, http://lists.samba.org/pipermail/rsync/2000-December/003349.html) is necessary to prevent rsync from failing on creating FIFOs or UNIX sockets on FreeBSD.

Hi, when running OpenSSH with EGD as entropy source, the sshd server connects to the EGD socket and leaves it open to re-seed on the fly. Unfortunately the connection is not checked when re-seeding, so that a failure or restart of EGD will lead to a "fatal()" abort of the sshd server process. Since a dying server process can not be accepted, I would recommend to not have sshd call it
