Hello, I am running Samba 2.0.7 on linux Redhat 7 kernel 2.2.22 as shown below. [root@serv aviad]# uname -a Linux serv.mobilitec.com 2.2.22-7.0.3smp #1 SMP Thu Nov 14 11:51:44 EST 2002 i686 unknown [root@serv aviad]# /usr/sbin/smbd -V Version 2.0.7 I encounter a problem with excwll files on sharing point which somtimes opens as a read only files, but I'm sure that only one person is using them at the same time. I found an article which explains to add to the smb.conf the two lines: force security mode = 0200 dos filemode = yes which didn't solve my problem. when restarting the samba server I found in the /var/log/samba/log.smb: (samba log file) [2004/08/25 16:48:14, 0] param/loadparm.c:map_parameter(1681) Unknown parameter encountered: "dos filemode" [2004/08/25 16:48:14, 0] param/loadparm.c:lp_do_parameter(2223) Ignoring unknown parameter "dos filemode" So I guess this command is working on later versions, and I'm trying to find the command which will work with this samba version. or to find any other suggestions to solve this problem below is the global part from the smb.conf and the relevant share point: [global] workgroup = MOBILITEC server string = Samba Server interfaces = eth0 eth0:0 encrypt passwords = Yes log file = /var/log/samba/log.%m max log size = 100 socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192 domain master = No dns proxy = No [morel work] path = /home/morel/work force directory mode = 0770 writeable = yes create mode = 0770 force create mode = 0770 directory mode = 0770 force group = Finance valid users = @Finance comment = morel work write list = @Finance force security mode = 0200 dos filemode = yes I would appriciate any help, Thanks in advance Aviad.
