Hi.
I patched with 76 and 77 both crash and oops.
That problem is fixed, but now I got other error with same setup:
crash # conntest-client-gai testlin4b tcp 1111
GAI ERROR -3: Temporary failure in name resolution
...but, trying it the other way around (adding for crash
/etc/hip/hosts -file, crash starts conntest-server and oops
conntest-client-gai), it works fine. Weird...
After these I deleted from /etc/hosts -files extra hostname lines
commented out with # -characters (sorry, I didn't put these # -lines
in my last message) and started everything from start (also did
'hipconf new hi default'). Problems disappeared and chapter 6. test
case seems to work.
