Hello,
I am setting up a suse linux v9.1 host to provide file and print
services to a mix of os/2 and windows clients. In this case windows is not
a problem. I am running into difficulty getting the os/2 clients to see
the resources on the linux server.
The main problem is the firewall. Without the firewall os/2 hosts have
no problem with accessing resources. With the firewall the hosts cannot
access the server.
There seems to be some problem related to ARP. The os/2 hosts broadcast
a request to a nameserver (x.x.x.255) looking for the resource. Without
the firewall there is an exchange of arp data; with the firewall, the
packets are blocked.
What port is the firewall blocking? In the Suse firewall config file
there is:
FW_SERVICES_EXT_TCP="139 445 760 http https imap imaps nfs smtp ssh"
FW_SERVICES_EXT_UDP="137 138 760 788:799 nfs 111"
Yet when I attempt to access the linux server, I find this in the
messages log:
Oct 31 16:52:34 sma-server2 kernel: SFW2-DROP-BCASTe IN=eth1 OUT=
MAC=ff:ff:ff:ff:ff:ff:00:03:ff:29:24:34:08:00 SRC=192.168.69.201
DST=192.168.69.255 LEN=78 TOS=0x00 PREC=0x00 TTL=64 ID=140 PROTO=UDP
SPT=137 DPT=137 LEN=58
00:03:ff:29:24:34/192.168.69.201 is the MAC/IP of the host requesting
info. The firewall dropped the broadcast packet even though the firewall
is configured to allow it. Am I reading the logs correctly?
