CIFS VFS: Send error in read = -13
Any ideas what this means? This happens from my FC5 box. My FC4 box does this just fine.
I get this in /var/log/messages any time that I attempt to read, copy or cat a file on my Windows 2003 server.
I've mounted the volume with
mount.cifs //server/share /mountpoint -o username=domain_admin_account
I can go into /mountpoint and touch a file. I can then run vi and save data into the file. However, when I try to cat the file I get permission denied and then CIFS VFS: Send error in read = -13 in my /var/log/messages. However, from Win2003, or FC4, I can see the contents of the file just fine and I mount with the same username/password.
I'm stumped.

Did you disable the numeric options in the 2003 server ?

I'm not sure what your question is asking? What are the "numeric options" in the 2003 server?

I have duplicated this problem at work.
Here is the deal, this appears to happen when the 2003 Server happens to ALSO be a domain controller.
I'm not yet sure how to fix it, but at least I know the scenario and can make it happen.

Hmmm, sorry, i can't find the correct word in english...
Ooops, i think i'd better sleep a little more... it is something like numeric signature which must be disable...
i use this one and it works great :
mount -t cifs -o username=windowsuser,workgroup=MYWORKGROUP "\\\\server\\share" /mount/point/

Ahh I'm also having this problem. The server is a win2003 small business server acting as a domain controller with active directory stuff running on it.
Previously until my upgrade to FC5, the following mount in fstab was working fine..
//10.10.10.90/preview /mnt/preview cifs defaults,uid=rus,gid=users,user=USER,password=PASS WORD,dom=monaco 0 0
Now, although they mount ok, I can list files and directories, but reading files gives me the dreaded "CIFS VFS: Send error in read = -13"
I've tried playing with the various sec= options as detailed in the cifs man page, but they don't seem to make any difference.

Try with smbfs instead of cifs to see !?

mount: unknown filesystem type 'smbfs'
and there's no kernel module for smbfs either. Looks like it's been completely recplaced by cifs in FC5

Arg, yeah, CIFS is the way to go now...
try this one now :
sudo mount -t cifs -o user=name,setuids,noperm,uid=500,gid=500 //server/share /mnt/windows-share
tell me what...

Same thing happens I'm afraid! It mounts OK, I can cd in to it, ls lists the files in there.. but doing 'less readme.txt' produces the CIFS error in /var/log/messages
Just to confirm, this is happening with the latest 2.6.16-1.2080_FC5 aswell as the initial 2.6.15-1.2054_FC5 kernel. I was hoping the kernel upgrade would solve the issue, but it seems not!
Using Nautilus to access the shares via smb:// urls works fine, but is not ideal because that only works for a sub-set of gnome applications that use gnome-vfs
I notice there's a few things in /proc/fs/cifs/ - I wonder if something in there needs to be 'tweaked'?

This is a problem with 2003 domain controllers and FC5. I filed a Bugzilla report on this in a prior post. Still waiting to hear anything
http://forums.fedoraforum.org/forum/...ight=2003+cifs
Personally, I must be able to mount the share using fstab because I have many scripts which backup my network. Until they get this corrected, I can't even consider using FC5.

I get this message:
CIFS VFS: Send error in read = -13
after doing this:
Packages Installed:
kernel.i686 2.6.16-1.2122_FC5
I think the problem is either not solved or was re-introduced.
What should I do?

Try booting to the old kernel (hopefully you kept it around) and see if the problem goes away.
I haven't had the problem again, but I also exclude kernel updates unless necessary. Right now, I am running on 2.6.16-1.2107
