Re: NT_Create: Anything special I need to know?
Hi The field 'FileType' in the NT_Create_ANDX is very sensitive. I have observed NT cliens crashing if that field was set to a value 1. I refered the SNIA document, and the description is missing :) Generally I have observed that if the create response is not correct, NT client will crash ( BSOD ). W2K handles the same packet without crashing. Hope this helps. Yogesh.
NT_Create: Anything special I need to know?
I'm going to do a very brief writeup of NT_CREATE_ANDX, but I remember hearing rumors dark lurking daemons. What do I need to know? What is there about this command that should be documented?

Re: Bizarre limit alert.
My first response was vague. Now that I've reviewed code I'll try again... I saw the same "packet drop" with an overlong WRITE_ANDX. The maximum buffer size an NT SP6 claims on the NEGOTIATE respone is 0x1104 (4356). This limit is not on the data, the limit includes the SMB header (32 bytes) and the SMB command. Based upon the size of an ECHO command I'd expect you could send 4319 bytes, not 4323, so on this topic you'll have to have the last word... sorry.

trouble with rpcclient setdriver using Samba 2.2.7a on RH Linux 7.3
Using Samba version 2.2.7a on a Red Had Linux 7.3 system (named ream, as in paper), I gave this command: rpcclient ream -c 'setdriver hp_233 "HP LaserJet 4050 Series PS"' and got the following printed on my screen: session setup ok Domain=[CS] OS=[Unix] Server=[Samba 2.2.7a] cmd = setdriver hp_233 "HP LaserJet 4050 Series PS" setdriver hp_233 "HP LaserJet 4050 Series PS" SetPrinter call failed! result was NT_STATUS_ACCESS_DENIED Here is what showed up in the log.smbd file: [2003/02/25 17:49:38, 0, pid=10207] rpc_parse/parse_spoolss.c:spoolss_io_devmod e(606) spoolss_io_devmode: Unknown specversion in devicemode [0x0] [2003/02/25 17:49:38, 0, pid=10207] rpc_parse/parse_spoolss.c:spoolss_io_devmod e(608) spoolss_io_devmode: please report to [EMAIL PROTECTED] [2003/02/25 17:49:38, 0, pid=10207] rpc_parse/parse_spoolss.c:spoolss_io_devmod e(704) spoolss_io_devmode: I've parsed all I know and there is still stuff left| [2003/02/25 17:49:38, 0, pid=10207] rpc_parse/parse_spoolss.c:spoolss_io_devmod e(705) spoolss_io_devmode: available_space = [-220], devmode_size = [0]!

Re: smbd load of large numbers of client
well here's the thing. Samba does a great job of managing the PC's and their romaing profiles. Two things you need to consider that I've found in our 800 machine environment. We had a problem with the number of small files and server performance. This is not Samba's fault in any way. We have 5300 users and they are spread over 8 filesystems with symlinks from /home. Some things you can do is mod the uid by 8 and that's the filesystem they fall into. anyway we had 8 million total student files. i just finished removing 2.4 million in IE and NS cache. Now things are much much smoother than the last few weeks at login time. that's number one. number two is build a fast i/o infrastructure. that means both network and disk. we use 10k 36GB SSA disks from IBM. they're *fast*. Microsofts use of roaming profiles is interesting in theory, but the practical application of having one server do everything is an issue especially when users cannot manage their profiles properly. roaming profiles can reduce a $125,000 RS/6000 to a doorstop if you're not careful. We are branching out and having one server for served software, one for H: (homes) space and one for profiles (on order). The new 630 with 4-Power4+ cpus at 1.45GHz each and 8GB memory for $40,000 is going to do nicely for us. (of course i have a really nice director who like to give me money) I'm in *NO* way indicating you will need to do this. We *need* to because of what we call the "top of the hour" effect where students log off to go to another class and login someplace else. this creates a tremendous amount of i/o for about 20 minutes - 10 of to 10 past the hour. our current server IBM-RS/6000-6H1 with 6 cpus and 6 GB memory can handle the punishment of 550 workstations all logging in at the same time. I cannot say for 800 since not all classrooms are full. Hope that helps. BTW, we are a community college with 11,000 students and 5300 of which actively use our 800 XP based PCs.

smbd load of large numbers of client
Hi, Is anyone running larges numbers of clients against Samba servers? Here I am thinking of 1000+ clients, and wanting to get a feel for the load of 1000+ smbds. I already know that at least with the 2.2.x base, smbd maintains 29 open file descriptors before it opens any files for users, but am wondering about the memory load (which should not be too bad with copy-on-write on modern UNIXen) and context switch load?

Re: [PATCH] Re: 3.0a21: "net ads lookup" for a child domain gotmessy output
How about this new patch (as in the attachment). The change I made from your
patch, is to add the while loop in pull_c_zero_string which was adopted from
pull_dotted_string. Now my domains are all happy. Otherwise, a grandchild
domain complains.
I am posting this to samba-technical list, since I though it was what you
intended to do, and we might get more testing of this.

vfs_recycle and create mode 770
@List I'd like to use the recycle as a per machine recycler using the option 'name = .recycle/%m' (because we have just some usernames without passwords) Works fine, but if a directory is created it uses the rights 700, therefor if a subdirectory should be created by antother user it doesn't get the permissions and the files will be purged. Any suggestions how i can change the create mode to 770.

Re: Bizarre limit alert.
I don't use ECHO yet, but I debugged much the same symptom on a WRITE. I recall the conclusion was that maximum buffer size includes the NB wrapper, but I'd have to revisit the code changed to be sure. NT dropping the WRITE had bad consequences of course :( I've been testing the SMB Echo message and found a very odd thing. If I send an echo request message to NT4 SP6 with a payload of 4323 bytes NT4 responds just fine. If the payload is 4324 bytes NT4 does not reply. Of interest, the payload of 4323 bytes generates one ECHO Request and two continuation messages on the (Ethernet) wire. The ECHO Request and first continuation message are 1514 bytes in (total) length. The last continuation message is 1498 bytes...16 bytes less than 1514. Hmmm... I like weird stuff like this.
