Hello Experts, my problem is about a ppp-chat connection which I manually to connect to a remote machine. The is a mgetty/callback running. I get the callback and establish a connection. That worked fine with version 8.0 but after the upgrade to 8.1 - it seems as if I get the connection but then I am blocked. I have added some statements which may help to show what happens. I am lost since I am a novice dealing with firewalls. And I only guess that it call be the firewall. Since the machines are uncritical, I can run tests without a firewall. How can I make sure that everything works, without a firewall? = How do I switch all this stuff down. I tried it but something seems to bolck me recieving data, though emailing works fine. Thanks a lot Michael tamboti:~ # ping 196.168.55.1 PING 196.168.55.1 (196.168.55.1) from 196.168.55.200 : 56(84) bytes of data. <CTRL-C> --- 196.168.55.1 ping statistics --- 15 packets transmitted, 0 received, 100% loss, time 14016ms tamboti:~ # ssh 196.168.55.1 <CTRL-C> tamboti:~ # SuSEfirewall2 stop Removing filter rules and disabling IP forwarding ...
