Am intarziat putin cu raspunsul la strace pentru ca sistemul a luat un
reboot atunci si nu mai facea figurile descrise. Acum au aparut din nou.
Din ce spune strace-ul si din comparatia cu ping pe un sistem asemanator
se pare ca are un timeout in linia cu 'poll', dar nu stiu la ce se refera.
write(1, "64 bytes from localhost.localdom"..., 81) = 81
gettimeofday({1325863785, 204212}, NULL) = 0
poll([{fd=3, events=POLLIN|POLLERR}], 1, 999) = 0 (Timeout)
gettimeofday({1325863795, 845223}, NULL) = 0
gettimeofday({1325863795, 845281}, NULL) = 0
sendmsg(3, {msg_name(16)={sa_family=AF_INET, sin_port=htons(0),
sin_addr=inet_addr("127.0.0.1")}, msg_iov(1)=[{"\10\0h\220<\"\0\2s\23
\7O\341\345\f\0\10\t\n\v\f\r\16\17\20
\21\22\23\24\25\26\27"..., 64}], msg_controllen=0, msg_flags=0},
MSG_CONFIRM) = 64
setitimer(ITIMER_REAL, {it_interval={0, 0}, it_value={1, 0}}, NULL) = 0
recvmsg(3, {msg_name(16)={sa_family=AF_INET, sin_port=htons(0),
sin_addr=inet_addr("127.0.0.1")},
msg_iov(1)=[{"E\0\0T\242\221\0\0@\1\332\25\177\0\0\1\177\0\0\1\0\0p\220<
\"\0\2s\23\7O"..., 192}], msg_controllen=20, {cmsg_len=20,
cmsg_level=SOL_SOCKET, cmsg_type=0x1d /* SCM_??? */, ...}, msg_flags=0},
0) = 84
P.S. Secventa de mai sus e exact copiata intre 2 write-uri "64 bytes
from localhost.localdomain"
