Hallo suse-security, every time a client (running NT4) issues the command "net time \<linuxserver>" the Linuxserver (SuSE8.2) reports an error in /var/log/messages Aug 6 16:09:16 <linuxserver> kernel: martian source 192.168.80.1 from 10.68.26.117, on dev eth2 Aug 6 16:09:16 <linuxserver> kernel: ll header: 00:50:04:45:33:f5:00:01:02:e2:39:4e:08:00 In this example 10.68.26.117 is the client ip adress. eth0 is the internal interface to the clients, eth1 external eth2 another internal network to which the client has no direct access 192.168.80.1 is <linuxserver>´s ip adress on eth2 The time synchronization attempt times out after some time on client side. If I stop SuSEfirewall2 'net time' works without problems. What has to be configured in SuSEfirwall2 to get 'net time' working? -- Mit freundlichen Grüßen, André Sänger
