I am still struggling with how to fix up Samba on our network. I'm running two samba servers. One with version 3.0.21b-1 on RH9, and another with version 3.0.10-1.4E.6 on RHEL 4. Neither are pdc's, and there is no pdc in the domain at all. The two networks are connected across the country via an IPsec tunnel. Users on one network access the other server have the same problem: after you go down about three levels, the response from the server gets very slow. Users on the same network have no problem. Does anyone have any ideas? Here are the smb.conf Server 1 3.021b-1 RH9 (turned off wins as a test to see if it would effect the slow response - it hasn't) [global] name resolve order = host lmhosts bcast #name resolve order = wins host lmhosts bcast #winbind enable local accounts = no hosts allow = 192.168.0.0/24 192.168.5.0/24 192.168.10.0/24 127.0.0.1 passwd program = /usr/bin/passwd %u dns proxy = no netbios name = KID logon script = netlogin.bat local master = yes workgroup = MOB debug level = 1 os level = 255 socket address = 192.168.0.153 hosts deny = 0.0.0.0/0 security = user add machine script = /usr/sbin/useradd -d /var/lib/nobody -g 100 -s /bin/false -M %u max log size = 50 log file = /var/log/samba/log.smbd socket options = IPTOS_THROUGHPUT TCP_NODELAY SO_SNDBUF=8192 SO_RCVBUF=8192 keepalive = 30 logon drive = H: interfaces = eth0 lo domain master = yes username map = /etc/samba/smbusers encrypt passwords = yes #wins proxy = no logon home = \\%L\profiles\%u\ #wins support = yes server string = DET - Kid #kernel oplocks = false unix password sync = yes logon path = \\%L\profiles\%u\ preferred master = yes bind interfaces only = yes domain logons = no Server 2 3.0.10-1.4E.6 RHEL 4 [global] log file = /var/log/samba/log.smbd name resolve order = host lmhosts bcast #name resolve order = wins host lmhosts bcast passwd chat = *New*UNIX*password* %n\n *ReType*new*UNIX*password* %n\n *passwd: *all*authentication*tokens*update d*successfully* socket options = TCP_NODELAY IPTOS_THROUGHPUT SO_SNDBUF=8192 SO_RCVBUF=8192 deny hosts = 0.0.0.0/0 prefered master = yes username map = /etc/samba/smbusers domain master = no interfaces = eth0 lo encrypt passwords = yes passwd program = /usr/bin/passwd %u wins proxy = no keepalive = 30 wins support = no #wins server = 192.168.0.153 #wins support = yes allow hosts = 192.168.0.0/24 192.168.5.0/24 192.168.10.0/24 127.0.0.1 dns proxy = no netbios name = ARN server string = SUN - Arn kernel oplocks = false unix password sync = yes local master = yes workgroup = MOB-SUN os level = 255 debug level = 1 socket address = 192.168.10.5 security = user bind interfaces only = yes max log size = 50 domain logons = no
