Failed To Set Socket Option Iptos_lowdelay

This option eventually arranges to close dead connections, returning unused memory and process-table entries to the operating system. Collins, CO 80523-1301 All I want is a chance to prove 'Money can't buy happiness' Previous message: [Samba] Strange errors in Samba Logs Next message: [Samba] Potential bug in latest build Watson Product Search Search None of the above, continue with my search Errors reported in the Samba logs: Failed to set socket option 1437876; CC; Samba; SO_KEEPALIVE; SO_RCVBUF; SO_SNDBUF; "Error Invalid Any incoming SMBwriteX call on a non-signed SMB/CIFS connection greater than this value will not be processed in the normal way but will be passed to any underlying kernel recvfile or have a peek here

To specify an argument use the syntax SOME_OPTION = VALUE for example SO_SNDBUF = 8192. Resolution WORKAROUND 1 Reduce your "log level" to 0. This is good if your server crashes constantly, but the performance costs are immense. Or that it's got the following optimization flags (oncompilation) set: CFLAGS="-O6 -mpentiumpro -march=pentiumpro-malign-loops=2 -malign-jumps=2 -malign-functions=2"?The options sound Ok, can anyone on the listchack on the version?

For read-only files, the fake oplocks provides the same functionality without actually doing any caching. No clients suffer from this problem now. Using this option is conjunction with "deadtime = 15" to close idle connection as fast as your working environment will allow.

Raw read and write These are important performance configuration

hmm? Close J. socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=65536 SO_SNDBUF=65536 TCP_NODELAY tells the server to send as many packets as necessary to keep delay low.

I'm also seeing the same errors: [2010/01/31 09:33:32, 2] lib/util_sock.c:442(set_socket_options) Failed to set socket option SO_KEEPALIVE (Error Invalid argument) [2010/01/31 09:33:32, 2] lib/util_sock.c:442(set_socket_options) Failed to set socket option TCP_NODELAY (Error Invalid There is also a follow symlinks option that can be turned off to prevent following any symbolic links at all. I increased the read speed to 500-600MBit/sec by enabling AIO and saw Samba using around 1-4% CPU on a Intel E2200. Reduce the logging level to 2 or under.

If the latter is the case please send the patch to [email protected] Has this problem got to do with the fact that I compiled my Sambausing GCC 2.95.1? Values greater than 128k will be silently set to 128k. Bellow are an explination of the options used above.

Note this option will have NO EFFECT if set on a SMB signed connection. navigate here This is the list of socket options currently settable using this option: SO_KEEPALIVE SO_REUSEADDR SO_BROADCAST TCP_NODELAY IPTOS_LOWDELAY IPTOS_THROUGHPUT SO_SNDBUF * SO_RCVBUF * SO_SNDLOWAT * SO_RCVLOWAT * Those marked with a '*' We cover how to setup Samba and a fully working example file. It may improve performance but user testing is recommended.

Bad options can be very BAD. This yields a marginal increase of speed until it reaches a point of diminishing returns. If you do turn off wide links, be sure to turn on getwd cache to cache some of the required data. http://justjoomla.net/failed-to/failed-to-start-up-socket-within-45000-ms-attempted-to-connect-to-the-following-addresses.html Any ideas how to fix > this? > > [2010/01/29 09:17:27, 0] lib/util_sock.c:set_socket_options(261) Failed to > set socket option TCP_NODELAY (*Error Invalid argument*) > [2010/01/29 09:17:27, 0] lib/util_sock.c:set_socket_options(261) Failed to >

This option will typically be used to tune your Samba server for optimal performance for your local network.

More information can be found at http://www.samba.org Options Explained min receivefile size This option changes the behavior of Samba when processing SMBwriteX calls.

I recollect problems we hadonce upon a time with one release of GCC, but itwas back in the summer...Could this problem also be because of some sort of a faulty kernel?(Although getwd cache option caches the path to the current directory, avoiding long tree-walks to discover it. Turning it off requires extra processing on every file open. This option gives us a minor speed up around 20%.

This will account for a 30 percent speedup by itself. Can someone help meout in this?

Windows 98 Explorer sets the bit in all packets transmitted, so if you turn this on, anyone with Windows 98 will think Samba servers are horribly slow.

SO_SNDBUF and SO_RCVBUF The send and receive buffers can often be the reset to a value higher than that of the operating system. The default is 10 seconds, which is reasonable. They also require the largest SMB packet structures, SMBreadraw and SMBwriteraw, from which the options take their names. We apologize for the inconvenience.

If you have already registered your product then please contact Customer Service directly for further assistance at [email protected] Instead, Samba will immediately return that the write request has been finished successfully, no matter if the operation will succeed or not. hide files provide a pattern to identify files hidden by the Windows client hide files will result in any file matching the pattern being passed to the client with the DOS To enable POSIX large write support (SMB/CIFS writes up to 16Mb) this option must be nonzero.

Lucia St. Database files should never be cached, nor should any files that are updated both on the server and the client and whose changes must be immediately visible. The default is zero, which disables this option use sendfile If this parameter is yes, and the sendfile() system call is supported by the underlying operating system, then some SMB read However, this option does not pose a performance problem.

What AIO does is that it let's Samba handle several file operations asynchronously. Want more speed? Cause Including the subnet mask on the interfaces line when the server has multiple internet addresses. aio write behind Samba will not wait until write requests are finished before returning the result to the client for files listed in this parameter.
