I installed nightly snapshot hrev43696 on my real mchine Lenovo ThinkPad T400. System worked amazing but from time to time he had some mistakes. I found some problems with ping command and gethostbyname function. Ping after installation works perfectly. But I have, in my local network, hosts that has only local names. I found information in this forum about how to setup local hosts names in file "/etc/host" by set configuration in file "/boot/common/settings/network/irs.conf". Observed that empty or filled file "irs.conf" generates following results:
~> ping 127.0.0.1 error: unknown protocol icmp: error 0 [No error] ~> ping localhost error: unknown protocol icmp: error 0 [No error]
I have written small console program, that only call the function gethostbyname and print her results:
/Home/Projekty/Testy>./ghbn 127.0.0.1 Host in "127.0.0.1"
h_name == "127.0.0.1" h_addrtype == 1 h_length == 4 h_addr_list == 127.0.0.1
/Home/Projekty/Testy>./ghbn localhost Host in "localhost"
gethostbyname( "localhost" ): Error, errno == 0, h_errno == 1.
And h_errnp == 1 this is error HOST_NOT_FOUND.
My /etc/host has values "127.0.0.1 localhost" and irs.conf is empty or has values "hosts local dns".
After removed file irs.conf, ping and gethostbyname working correctly but only with dns.
On Linux the test program works perfectly.
