Hello All I am setting up a new samba server. It is a stand alone server and just needs a simple file share. Some info first: Harware: HP ML 570 O/S: Fedora Core 5 with all updates uname -a = Linux "hostname removed" 2.6.18-1.2200.fc5smp #1 SMP Sat Oct 14 17:15:35 EDT 2006 i686 i686 i386 GNU/Linux rpm -qa | grep samba system-config-samba-1.2.34-1 samba-common-3.0.23c-1.fc5 samba-client-3.0.23c-1.fc5 samba-3.0.23c-1.fc5 I add a group groupadd mygroup I add my users to linux: useradd -g mygroup -s /bin/false -d /dev/null user1 smbpasswd -a user1 Standard config file with this added that works: [myshare] comment = myshare path = /myshare valid users = user user1 user2 public = no writable = yes printable = no create mask = 0765 testparm smb.conf gives no errors and i can connect to share this does not work [myshare] comment = myshare path = /myshare valid users = @mygroup # valid users = user user1 user2 public = no writable = yes printable = no create mask = 0765 testparm smb.conf gives no errors, but when I try to connect I get the error \\nameofserver\myshare is not accessible You might not have permission to use this network resource The specified network name is no longer avaiable from the log file in /var/log/samba: From: http://www.samba.org/samba/docs/Samba3-HOWTO.pdf [2006/10/18 10:37:31, 0] lib/fault.c:fault_report(45) ==============================================================[2006/10/18 10:37:31, 0] lib/util.c:smb_panic(1614) PANIC (pid 3215): internal error [2006/10/18 10:37:31, 0] lib/util.c:log_stack_trace(1721) BACKTRACE: 19 stack frames: #0 smbd(log_stack_trace+0x2d) [0x63c8ad] #1 smbd(smb_panic+0x5d) [0x63c9dd] #2 smbd [0x62851a] #3 [0x110420] #4 /lib/libc.so.6(__strdup+0x1f) [0x83a893] #5 /lib/libnsl.so.1(nis_list+0x5d2) [0x2e8b5f] #6 /lib/libnss_nisplus.so.2(_nss_nisplus_setnetgrent+0x8f) [0x2bc62e] #7 /lib/libc.so.6(innetgr+0xb2) [0x8b5d05] #8 smbd(user_in_netgroup+0x65) [0x4731e5] #9 smbd(token_contains_name_in_list+0x23d) [0x475bdd] #10 smbd(user_ok_token+0x8f) [0x47600f] #11 smbd [0x4d388f] #12 smbd(make_connection+0x194) [0x4d4fa4] #13 smbd(reply_tcon_and_X+0x21d) [0x4988ed] #14 smbd [0x4d00e0] #15 smbd(smbd_process+0x7ab) [0x4d121b] #16 smbd(main+0xbd0) [0x6eaf90] #17 /lib/libc.so.6(__libc_start_main+0xdc) [0x7e64e4] #18 smbd [0x45b701] [2006/10/18 10:37:31, 0] lib/fault.c:dump_core(173) dumping core in /var/log/samba/cores/smbd The same exact setup works on another server, and I am not sure what I have done.
