Have you tried a network capture with something like WireShark to compare the
CIFS mount with smbclient and Windows 7?

Have you tried a network capture with something like WireShark to compare the
CIFS mount with smbclient and Windows 7?
No, i have not try that. But what can i see in wireshark traffic ? I see the logic -
when i reboot to windows - files transfer ok in both directions
windows 7 on another computers work with server nice
NFS mount from my Linux work nice (but i don’t use it because wrong security settings on server-side) - (this is about LAN device driver - looks like all ok with driver)
smbclient files transfer between my computer and Server - work nice (and this again is about LAN device driver - all ok with driver)
CIFS mount - writing - excellent speed.
CIFS mount - reading - is ugly slow.
All this things looks like cifs.ko module, or something wrong in kernel.
i have updated kernels and cifs-utils and smbclient rpm-s, but all results is the same.
What can i do with sniffer like wireshark ? (of course - i’m on work, and i can tune linux not all time) - what i can to see in TCP headers ? How can i use it ?
Primary question: How can i mount share with smbclient ? This is possible ? I have not SMBFS fs support in system.
How can i mount this share ? (NFS is wrong way - i can’t change server security parms, and i don’t want start debating about that)
I feel myself very strange, because in 2011 year, i need analyze old as s**t CIFS protocol, instead of just working with graphics as all others. This is a time killing. And our Server is not windows server - but Solaris. All systems - windows 7, XP and OSX work nice with it. Only linux is killing time for tuning and recompiling, instead of just work. As always.
==== venzkep, sorry, but what i need to catch from traffic? And where i can find guide with…With steps about analyze CIFS protocol problems using wireshark?

I’m not sure just what you’ll find. Smaller frames? Resent packets? Un
needed traffic? Something is different between the different methods. What
happens in a browser if you use:
smb://<servername>/<sharename>

Thanks… Last driver compiled and installed (autoinstall.sh ) - but same result with speed… I also try it with kernel-vanilla and compile last realtek driver - same… i don’t know what i can do more. Firewall is down. Apparmor uninstalled.
But Same machine - reboot to windows and nice speed in all directions. Reboot to linux - slow reading from cifs mounted share. But writing is roket-fast.

Thanks you. Only konqueror can do smb:\
Wireshark… i can’t understand frames and packets, because learning TCP headers is really not my target skill… I’m graphics designer. I can do some compiling, some tune, but comparing difference between TCP headers - is more than i can give for OS. Really. I understand when steps like that is needed for some beta-software, or, for example, testing new protocol plugin for messenger…
But i have problem with oldest thing - mount.cifs. Peoples ask me - “why you working so slow?? what you doing??” i say “i rebuild linux drivers kernel…reinstall…etc”
I’m really looking forward to the time when Linux will be easy to install and work on it, without brain fracturing. I spend a lot of time for reading articles and huge manuals about the simplest things - connect remote CIFS shares.
Instead of working. I have tried all possible options in the fstab, and /ets/modprobe.d… smbclient work nice and fast - read and write. NFS work nice - read and write. CIFS work slow. i need to stop that time killing i don’t want connect with CIFS developers or any. This is too many than i can do for this OS.
I’m happy to see that. And of course i read some prefs from Ubuntu:

i need some opinions from all who can help:
Hou do you think, can this solve my problem:
I want get the same kernel what i have seen in Ubuntu - and compile it and use in OpenSUSE 11.4.
Can this help me ?
p.s. i have nice writing speed to mounted CIFS, and slow reading from. Can i solve my problem with using Ubuntu’s kernel source Linux ubuntu 2.6.32-21-generic ? Ubuntu show me great reading and nice writing speed.
All right. I’m very impressed with the hurricane-productivity of this discussion.
The last question (if there even anyone still alive here)
It’s simple. Ubuntu passes the data well. Windows - too. Network equipment properly. How and where can I send a bug-report about OpenSUSE 11.4 CIFS problems ?

Yes it might help but it’s very hard to tell for sure if You’re not a kernel developer.
You can check this for the latest kernels : openSUSE News
Or compile the kernel from kernel.org the same way You would do that on any other linux. There’s literally tons of tutorials out there.
Here are some other kernel packages You might want to try out : Index of /repositories/Kernel:/openSUSE-11.4
Be advised that messing with the kernel can render your system unbootable and it’s not that easy to fix. If You’re as careless as me You can even delete all the kernels on your system.
Also check out kernel multiversion zypper config option if You will be installing different kernels from .rpm packages. There are a lot of threads on the forum about this.
I honestly don’t know. I guess it’s a samba client/kernel version combination but that’s just a wild guess. It might be that only certain kernel mixed with certain samba version will work as expected. It might be also a bug on the Solaris side which does not affect the Windows implementation or the one that You’ve got on Ubuntu. I think You will never know for sure.
