Hi, I run a Veritas cluster server with two different samba's 2.0.7 compiled with SUNWspro 4.0 (gcc 2.95 leads to the same results) on Solaris 7 UltraSPARC 60 server. One compiled with --prefix=/opt/samba-test the other with --prefix=/opt/samba-eng. To avoid using 127.0.0.1 or 0.0.0.0 when both smbd's running on the same cluster host I set this in both smbd.conf /opt/samba-test/lib/smb.conf: [global] workgroup = FORCE server string = Engineering Samba %v, Host: %h, your machine: %m netbios name = pollux interfaces = 10.254.1.22/16 bind interfaces only = true preserve case = yes short preserve case = yes encrypt passwords = yes update encrypted = no null passwords = yes username map = /opt/samba-test/private/users.map password server = md-deu-force01 sr-deu-gold01 sr-deu-gold02 sr-deu-data04 wins support = no wins server = 199.182.40.12 wins proxy = no name resolve order = wins host bcast domain master = no local master = no os level = 35 nt acl support = yes unix password sync = yes passwd program = /bin/passwd %u passwd chat = *New*password* %n\n *new*password* %n\n *changed* passwd chat debug = yes security = domain status = yes printing = sysv printcap name = lpstat load printers = yes guest account = samba map to guest = Bad User default service = reference log file = /opt/samba-test/var/log.%m max log size = 10 debug level = 1 syslog = 0 share modes = yes message command = csh -c 'cat %s > /dev/console;rm %s' & socket options = TCP_NODELAY dead time = 5 sync always = 1 config file = /opt/samba-test/lib/smb.conf.%m oplocks = yes fake oplocks = no read raw = yes write raw = yes read prediction = yes getwd cache = yes time server = yes /opt/samba-eng/lib/smb.conf with only difference to above smb.conf: netbios name = castor interfaces = 10.254.1.21/16 bind interfaces only = true socket address = 10.254.1.21 ... log file = /opt/samba-eng/var/log.%m ... config file = /opt/samba-eng/lib/smb.conf.%m ...
