Thank you for help, but problem still exists. Here is what have I done now: Chapter 6: crash and oops: # modprobe hipmod # tools/hipconf add hi default (addresses come up in /proc/net/hip/lhi -files) With oops: # test/conntest-server tcp 1111 crash: # test/conntest-client-gai oops tcp 1111 Text typed in crash appears to oops' console. After that I shut down conntest-xxs in oops and crash and: oops: # nc6 -l -p 12345 crash: # tools/hipconf add map <hit of crash> <ipv6 addr of crash> where <hit of crash> is from crash's /proc/net/hip/lhi and <ipv6 addr of crash> is 3ffe::1 it gives: action=1 optc=2 # nc6 <hit of oops> 12345 ipv6 address is 3ffe::1 as in examples and I took <hit of oops> from oops' /proc/net/hip/lhi, tried both, crash still says: nc6: unable to connect to address XXX, service 12345 where XXX is <hit of oops>. Do I need to use 'hipconf add map' also in oops? -Teemu Väisänen 2005/8/23, Miika Komu <miika@xxxxxx>: ... > You can use conntest-xx but they just connect, send a message and then > quit. nc6 is nicer because you can actually stream some data.
