Dear all, In my system, two containers need to exchange data as quick as possible and the two containers are hosted by the same physical machine, I wonder if socket is the only method for communication between containers? Thank you. Cheng Wang

...have 256mb of ram and you''ve probably by now added up that the above comes to 320mbytes. so i started looking at ways to minimise the memory usage. first, reducing each machine to only having 32mb of ram, and secondly, on the host, creating a MASSIVE swap file (1gbyte), making a MASSIVE shmfs/tmpfs partition (1gbyte) and then creating swap files in the tmpfs partition!!! the reasoning behind doing this is quite straightforward: by placing the swapfiles in a tmpfs, presumably then when one of the guest OSes requires some memory, then RAM on the host OS will be used until such time as th...

...r communication between containers? If you have an area of filesystem that is shared + writable to both containers, they could create UNIX sockets in that filesystem, rather than TCP sockets. Also they could create named FIFO pipes. Another option would be to create a shared memory backed file in shmfs or hugepagefs and expose it to both containers.

-----BEGIN PGP SIGNED MESSAGE----- Hello samba team, hi there when I try to copy, move to the Samba server it generates a nice kernel bug. I'm currently running samba-2.0.7-pre3 but samba-2.0.6 also has this problem. Reading files off the vfat share works fine. Also writing small ascii and binary files works, but if the binary file is about 3 Mb or larger. I'm currently running
