[Samba] Auth prompt if access share by machine name
I have a AD domain running fine, and I want to add my first linux server. To keep things simple, I do NOT want to integrate it into my domain. I just want to create a share that anyone can read/write to. I've created the setup below which works fine only if I access the linux share box by ip address from windows; eg: \\1.2.3.4 This gives me full r/w permission without any authentication prompts. However, if I access the box using the name (eg: \\server) then I get an authentication prompt I can't get past. I've read the online docs but can' find a solution. Can someone help? thanks, MD results of my testparm are below. I've replaced my real netbios domain name with MYDOMAIN, and hidden the wins IP. I've also disabled print sharing which explains the printcap stuff. Load smb config files from /etc/samba/smb.conf Processing section "[movies]" Loaded services file OK.

RE: [Samba] Connection dropped when copying large files to a SambaServer
I'm not sure how best to proceed with this one either...short of generating a huge amount of debug info. One clue (should someone be reviewing the nearby code), is that the failure appears to occur around the time of file close! In my tests, I can write out 65GB of data no problem, but around the time of file close smb hangs up. I don't think it's an underlying filesystem issue since an equivalent write using NFS to the same server works great.

We would need much more information. I know it's difficult to do higher debug levels for this data rate, but without more info we just can't diagnose this remotely.

I can see h/w being a cause in many cases. We've reproduced this on 2 different servers with 2 different storage technologies. And once using Backup Exec and once using Ghost.

RE: [Samba] Connection dropped when copying large files toa SambaServer
But SAMBA showed in the stack dump during the crash (and this system was running stable for months - and crashed during our first big samba transfer).

RE: [Samba] Connection dropped when copying large files toa SambaServer
Just another clue for you: The samba crash/lockup appears to happen at the END of a large file write. I can write 2gb or 65gb files across the lan to the samba share, but when the file is (or is about to be) closed, samba locks up the share.

RE: [Samba] Connection dropped when copying large files to a SambaServer
Not hijacking the thread here...just adding more info as I have the same issue. I run Samba 3.0.23c (on FC6 64 bit), and am backing up from a Windows box to my Samba share. Sometimes it works great; other times the samba share locks up (I need to restart the smb service); and last week samba caused a kernel panic. I can sometimes get 65GB onto the share before it locks up. I can backup to the share using NFS (using Windows Services for Unix) without issue, but not to Samba. My relevant smb.conf settings are: reset on zero vc = yes read raw = yes socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 Strangely, smb logs NO errors!

[Samba] Samba behaving badly with quotas
I have successfully added disk quotas to my FC6 system, so that the user "backup" cannot create files more than 1 block on / The reason I implemented this was because I backup my system to a USB drive mounted to /media/drivebay/backup1. However, if the drive is not mounted, then my root drive fills up (writing to the /media/drivebay/backup1 folder) and linux hangs. The problem is, that the user quota applied to / is also applying to my /media/drivebay/backup1 device too -only when accessed remotely as a SAMBA share! (I don't think that it should; although /media/drivebay is on the same partition as / the backup1 subdir is my mountpoint). In other words, the user "backup" cannot write more than 1 block to /media/drivebay/backup1 when accessing via SAMBA. Why is this - and how do I fix it? My goal is to prevent the user backup from writing more than 1 block to / , but as much as he wants to /media/drivebay/backup - when copying data from remote machines. What do I have to change? (I know that I could do something similar in a script, but I want to learn about quotas). the usrquota program does not exist in my distro (FC6), but "repquota /media/drivebay/backup1" shows: repquota: Mountpoint (or device) /media/drivebay/backup1 not found. repquota: Not all specified mountpoints are using quota. This suggests that quotas are not applied to that mount point. HoweverI can r/w just fine as user "backup" with quotas off, and not with quotas on.
