Bug#490530: libc6: gethostbyaddr() times out if reverse dns not found
Package: libc6
Version: 2.7-10
Severity: normal
I noticed that when I tried pinging kalus.dk (which does not have
reverse DNS at the time of writing), ping would only send a packet
every 5 seconds.
[EMAIL PROTECTED] ~ host kalus.dk
kalus.dk has address 89.233.27.15
kalus.dk mail is handled by 10 mail.kalus.dk.
[EMAIL PROTECTED] ~ host 89.233.27.15
Host 15.27.233.89.in-addr.arpa. not found: 3(NXDOMAIN)
[EMAIL PROTECTED] ~ ping kalus.dk
PING kalus.dk (89.233.27.15) 56(84) bytes of data.
[5 second pause]
64 bytes from 89.233.27.15: icmp_seq=1 ttl=56 time=6.21 ms
[5 second pause]
64 bytes from 89.233.27.15: icmp_seq=2 ttl=56 time=5.89 ms
[5 second pause]
64 bytes from 89.233.27.15: icmp_seq=3 ttl=56 time=5.98 ms
[5 second pause]
64 bytes from 89.233.27.15: icmp_seq=4 ttl=56 time=4.48 ms
I tracked it down to the function call char *pr_addr in ping.c, when calling
gethostbyaddr() :
/* pr_addr -- Return an ascii host address as a dotted quad and optionally
with a hostname. */
char *pr_addr(__u32 addr) {
struct hostent *hp;
[...]
hp = gethostbyaddr((char *)addr, 4, AF_INET);
[...]
}
I see no reason why it should take 5 seconds to find out that reverse DNS is
not available, when the host command returns the answer immediately.
Doing a strace I get (selected parts of trace):

I noted the

Which seems suspecious.
