dtrace of a Samba nbench run shows
Hi folks, I have been using dtrace, and particularly procsystime, to measure Samba system call usage stuff. This is what I get: cs-cc1# ./procsystime -n smbd Tracing...

Re: FreeBSD as Samba Server and Windows as Client

Previously , I tried to make a FreeBSD 9.1 amd64 as Samba server and connect a Windows XP as a client computer . By using The FreeBSD Handbook , many documents from www.samba.org and Internet , I could not be able to access to the FreeBSD Samba server from Windows XP : Continuously I have received Access denied error message in Windows XP although in the server the related directory and files have mode rwx-rwx-rwx . The same message is produced even for Linux Samba Server . The examples given in the documents are partial statements without actually used files / statements in such a setting , and sometimes inconsistent or contradictory with each other because they are mostly written manually . If a working , applicable set of files / statements are supplied , it will be appreciated very much . After a successful implementation , I will send an e-mail about this set up as an example for the FreeBSD Handbook to share our information with other people in need . All I can tell you is that it is definitely possible using FreeBSD. The FreeNAS folks do exactly that as does the company I work for. I do not have the time to spend helping you get it going and I note that you do not tell us which version of Samba you are using, but it does work. Have you tried setting the permissions correctly on the directory you are sharing? Do you know if it is getting Access Denied trying to access the Share or trying to create a file. -- Regards, Richard Sharpe (何以解憂？唯有杜康。--曹操) ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Does anyone know how to install FreeBSD 8.3 under Virtual Box 4.2.6?
Hi, I booted the FreeBSD 8.3 DVD1 under Virtual Box, but it crashes in VB 4.2.6 under Win 7 and Linux. Seems to install OK on QEMU/VMM under Linux ... Does anyone know how to get it to run under Virtual Box? -- Regards, Richard Sharpe (何以解憂？唯有杜康。--曹操) ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

I assume you mean the host here. Since it has installed under QEMU/vmm on Linux, I guess that I have HW Virtualization enabled. Actually, I know that this is the case, since I have run OpenIndianna under Virtual Box as well as Windows Server 2008. You don't specify if you are attempting i386 or amd64. True. AMD64. Maybe I need to check that. VB needs to know if you're running a 32 bit or 64 bit guest OS. A higher degree of details would be nice. -- +---++ | Vennlig hilsen, | Best regards, | | Trond Endrestøl, | Trond Endrestøl, | | IT-ansvarlig, | System administrator, | | Fagskolen Innlandet, | Gjøvik Technical College, Norway, | | tlf. mob. 952 62 567, | Cellular...: +47 952 62 567, | | sentralbord 61 14 54 00. | Switchboard: +47 61 14 54 00. | +---++ -- Regards, Richard Sharpe (何以解憂？唯有杜康。--曹操) ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Have there been any fixes for long TCP delays with FreeBSD 8.3 or 9.x?
Hi folks, I am seeing a problem when copying large files via SMB/Samba from a FreeBSD 8.0-based system (with Samba 3.6.6 and ZFS etc) where eventually Windows drops the connection. However, it seems, based on three captures I have, that what has happened is that FreeBSD has not supplied any data on the connection for 50-60 seconds and the Windows 60-second timeout trips. In each case, what I see is a large number of 1500-byte frames go out. Then Windows ACKs a reasonable amount of data, 30+K or so, and then sends another ACK to ack everything so far received. Then in two cases, after about 52 seconds I see some more data in two of the captures I have but after a further few seconds, Windows disconnects. In the last capture, there was no further data for 60 seconds, so Windows disconnected. I know there should have been more data because: 1. The READ requests are for 64kiB and there is still data to come and the sequence numbers match up. 2. In my Samba traces I know that Samba has gone on to process the next SMB2 command in sequence and the time difference between these are of the order of 1mS and Samba in this case is operating in sync mode where it does not read the next command off the socket until it has finished writing the response for the previous command to the socket. The system is relatively idle. Only one smbd and some web traffic (inbound as a result of a get). I am hoping that this describes a known problem. I can provide captures on request. They will have to be cut-down as they are 300 to 500MB in length. -- Regards, Richard Sharpe (何以解憂？唯有杜康。--曹操) ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
