I'm trying to get Samba working, between Win95 and RH 7.1. I can't get the Win95 machine to see the Linux samba server, though. It is unable to "Browse the network neighbourhood".
Both machines are plugged into a firewall/4-port ethernet hub, and both can use see the internet, so I know TCP/IP is working okay. I went through the "Using Samba" troubleshooting guide step by step. Everything checks out up to the test on the Win95 machine that tries to do a "net use x: \\posh\public", which fails. Samba uses ports 137 and 139, and I gather that RH 7.1 has firewalling. So I applied some ipchains rules that I garnered from Jon Clarke's "firewall.sh" script he mailed a while back: #!/bin/sh INTERNAL_NET=192.168.1.0 DSL_IF=eth1 INTERNAL_IF=eth1 ipchains -A forward -p all -s $INTERNAL_NET -i $DSL_IF -j ACCEPT ipchains -A input -p all -s $INTERNAL_NET -i $INTERNAL_IF -j ACCEPT ipchains -A output -p all -d $INTERNAL_NET -i $INTERNAL_IF -j ACCEPT So now an ipchains -L -n shows: Chain input (policy ACCEPT): target prot opt source destination ports [...] REJECT tcp -y---- 0.0.0.0/0 0.0.0.0/0 * -> 7100 ACCEPT all ------ 192.168.1.0 0.0.0.0/0 n/a Chain forward (policy ACCEPT): target prot opt source destination ports ACCEPT all ------ 192.168.1.0 0.0.0.0/0 n/a Chain output (policy ACCEPT): target prot opt source destination ports ACCEPT all ------ 0.0.0.0/0 192.168.1.0 n/a I think the problem is that DNS can't resolve the 2 local machine names (Samba server "posh" and Win95 client "coo"). I believe this is because DNS is being provided by Optus, but posh and coo are are local 192.168.1.* network addresses, so you wouldn't expect them to be resolved by DNS. Consequently, I have no idea to fix the problem! Because /etc/host.conf says the order is: "hosts,bind", it appears that nslookup doesn't pay attention to /etc/host.conf?! So if I try to do an nmblookup on the Samba server (posh), I just get: $ nmblookup -S posh doing parameter workgroup = localdomain [...] doing parameter domain master = yes doing parameter preferred master = yes doing parameter domain logons = yes doing parameter wins support = yes doing parameter dns proxy = yes pm_process() returned Yes added interface ip=192.168.1.100 bcast=192.168.1.127 nmask=255.255.255.128 bind succeeded on port 0 Socket opened. querying posh on 192.168.1.127 name_query failed to find name posh posh (the Linux Samba server0 is 192.168.1.100, coo (the Win95 client), is 192.168.1.101 I can ping the Samba server by short name (maybe only because I created a c:\windows\lmhosts file). Everything is set up as per the "Using Samba" book, except for the fact that I *can't* enable WINS resolution on Win95. When I choose that, and specify the IP address of the Samba server, and reboot, I find upon rebooting that it's reconfigured itself to disable WINS. If I choose instead to enable WINS via DHCP, that sticks. (But I still can't browse the network.) Is this a symptom of the Samba server not providing WINS resolution correctly? With WINS provided by the DHCP server (which knows nothing about Samba), attempts to browse the network take about 30 seconds before they eventually give up and fail. The other way, WINS via my Linux machine running Samba, means the Win95 browse attempts fail straight away. Below, is what I see when I browse the network from Win95 while running tcpdump -i eth1 on the Linux machine - the "posh.localdomain tcp port netbios-ssn unreachable" looks bad, but I'm afraid I'm well out of my depth here.
