Hi all, Hope somebody can help. I am obviously not a samba guru... I've installed a new server and tried to migrate my existing configuration and users.. I'm using FC6 and Version 3.0.24-7.fc6. Unfortunately when I performed the install on the new server, I didn't make sure my user UID and GID's where the same as the previous server which resulted in all sorts of odd behaviour particulary with the joining of the domains. I then manually altered all the user UID's and GID's (redoing groups almost entirely) to reflect the original configuration. Lo and behold it worked. After redoing all the 'Machine trust accounts' I'm now in a situation where Samba seems to be working HOWEVER..... After logon when I first try to access a share samba does a dump and I get an error message. On retrying all seems to work. Below is a copy of the dump messages and smb.conf .. Any help would be appreciated +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Sep 9 10:32:29 SOS14UF smbd[27889]: [2007/09/09 10:32:29, 0] lib/util_sec.c:assert_uid(101) Sep 9 10:32:29 SOS14UF smbd[27889]: Failed to set uid privileges to (-1,531) now set to (0,0) Sep 9 10:32:29 SOS14UF smbd[27889]: [2007/09/09 10:32:29, 0] lib/util.c:smb_panic(1621) Sep 9 10:32:29 SOS14UF smbd[27889]: PANIC (pid 27889): failed to set uid Sep 9 10:32:29 SOS14UF smbd[27889]: Sep 9 10:32:29 SOS14UF smbd[27889]: [2007/09/09 10:32:29, 0] lib/util.c:log_stack_trace(1728) Sep 9 10:32:29 SOS14UF smbd[27889]: BACKTRACE: 22 stack frames: Sep 9 10:32:29 SOS14UF smbd[27889]: #0 smbd(log_stack_trace+0x2d) [0x802253fd] Sep 9 10:32:29 SOS14UF smbd[27889]: #1 smbd(smb_panic+0x5d) [0x8022552d] Sep 9 10:32:29 SOS14UF smbd[27889]: #2 smbd [0x8022b63e] Sep 9 10:32:29 SOS14UF smbd[27889]: #3 smbd [0x800a692c] Sep 9 10:32:29 SOS14UF smbd[27889]: #4 smbd(pop_sec_ctx+0xa2) [0x800a6ac2] Sep 9 10:32:29 SOS14UF smbd[27889]: #5 smbd(unbecome_root+0x17) [0x8009bc97] Sep 9 10:32:29 SOS14UF smbd[27889]: #6 smbd(gid_to_sid+0x10e) [0x801dfcde] Sep 9 10:32:29 SOS14UF smbd[27889]: #7 smbd [0x800af1cc] Sep 9 10:32:29 SOS14UF smbd[27889]: #8 smbd(get_nt_acl+0x4c0) [0x800b5470] Sep 9 10:32:29 SOS14UF smbd[27889]: #9 smbd(vfswrap_fget_nt_acl+0x2b) [0x800aa45b] Sep 9 10:32:29 SOS14UF smbd[27889]: #10 smbd(is_visible_file+0x2ca) [0x8005910a] Sep 9 10:32:29 SOS14UF smbd[27889]: #11 smbd [0x8005966d] Sep 9 10:32:29 SOS14UF smbd[27889]: #12 smbd(dptr_ReadDirName+0x51) [0x800596d1] Sep 9 10:32:29 SOS14UF smbd[27889]: #13 smbd [0x8009150c] Sep 9 10:32:29 SOS14UF smbd[27889]: #14 smbd [0x800947e1] Sep 9 10:32:29 SOS14UF smbd[27889]: #15 smbd(handle_trans2+0x24b) [0x800950fb] Sep 9 10:32:29 SOS14UF smbd[27889]: #16 smbd(reply_trans2+0x6d7) [0x8009b4a7] Sep 9 10:32:29 SOS14UF smbd[27889]: #17 smbd [0x800b7f70] Sep 9 10:32:29 SOS14UF smbd[27889]: #18 smbd(smbd_process+0x7ab) [0x800b909b] Sep 9 10:32:29 SOS14UF smbd[27889]: #19 smbd(main+0xbd0) [0x802d4150] Sep 9 10:32:29 SOS14UF smbd[27889]: #20 /lib/libc.so.6(__libc_start_main+0xdc) [0x368dec] Sep 9 10:32:29 SOS14UF smbd[27889]: #21 smbd [0x80043051] Sep 9 10:32:29 SOS14UF smbd[27889]: [2007/09/09 10:32:29, 0] lib/fault.c:dump_core(173) Sep 9 10:32:29 SOS14UF smbd[27889]: dumping core in /var/log/samba/cores/smbd Sep 9 10:32:29 SOS14UF smbd[27889]: +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ My samba configuration file is +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ # Samba config file created using SWAT # from 192.168.99.200 (192.168.99.200) # Date: 2005/10/05 09:17:35 # Global parameters [global] workgroup = SOS14UF netbios name = SOS server string = SOS UFA interfaces = eth1 log file = /var/log/samba/log.smbd printcap name = /etc/printcap add machine script = /usr/sbin/useradd -d /dev/null -g 1000 -s /bin/false -M %u logon script = %u logon path = \\192.168.14.100\profiles\%u logon drive = H: logon home = \\192.168.14.100\home\%u domain logons = Yes preferred master = Yes domain master = Yes wins support = Yes create mask = 0777 force create mode = 0777 force security mode = 0777 directory mask = 0777 force directory mode = 0777 force directory security mode = 0777 [Homes] comment = Home Directories read only = No browseable = No [printers] comment = All Printers path = /var/spool/samba printable = Yes browseable = No [print$] comment = Printer Drivers path = /etc/samba/drivers write list = root guest ok = Yes [netlogon] comment = Login scripts path = /usr/SOS/netlogon browseable = No [profiles] comment = User profiles path = /usr/SOS/profiles read only = No create mask = 0600 force create mode = 0700 force security mode = 0700 directory mask = 0700 force directory mode = 0700 force directory security mode = 0700 [home] comment = This is private storage area path = /home/%u read only = No create mask = 0700 directory mask = 0700 [Public] comment = Public space to exchange file and share information path = /usr/SOS/clientdata/Ushare invalid users = timecard read only = No guest ok = Yes hide special files = no hide unreadable = Yes [f-prot] comment = F-Prot anti virus definitions path = /usr/local/f-prot/lan read only = Yes guest ok = Yes [Tosh1] comment = Toshiba Dinasore thingy path = /var/spool/samba printer admin = root read only = No guest ok = Yes printable = Yes printer name = Tosh1 use client driver = Yes [Gbake] comment = Global Bake Backup files path = /etc/SOS/SOSBackup/Backup read only = No guest ok = Yes [MYOB] comment = MYOB data path = /usr/SOS/clientdata/myob read only = No guest ok = Yes ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Regards Brad Horrocks -- Secure Office Services ABN 75 196 364 531 19 Burrendong Road COOMBABAH QLD 4216 Ph. +61 7 5537 4955 Fx. +61 7 5537 4966 Mob.+61 (0)404142690 web: http://www.secureoffice.com.au
