Funk) Newsgroups: comp.sys.apollo Subject: tcp/ip question Message-ID: <8812090847.AA15551@umaxc.weeg.uiowa.edu> Date: 9 Dec 88 08:46:43 GMT Sender: usenet@ucbvax.BERKELEY.EDU Organization: Iowa Computer Aided Engineering Network, University of Iowa Lines: 19 Does the Apollo version of /etc/ping use a non-standard icmp packet? There are various machines on the internet that will not respond to a ping from an Apollo but will respond to pings from other types of machines on our campus (such as bsd VAXes, Suns, Encore, etc). I know it is not a routing or connectivity problem because the remote hosts will respond to a ftp or telnet connect request from the Apollos. I don't think that it is a filtering problem in our gateway because other remote hosts will respond to pings from the Apollos. I would appreciate any suggestions as to what is going on or how to fix it. Specifics: OS: SR9.7.x tcp/ip v3.1 non-responding remote host: eddie.mit.edu (18.62.0.6) responding remote host: umix.cc.umich.edu (35.1.1.10) Dave Funk University of Iowa
