What does "arp -n" show? (In reply to comment #2) > What does "arp -n" show? "arp -n" shows the correct arp entry. Since the conversion of the raw IP address to the name is done in user-apce (libc), this is not a kernel issue. (In reply to comment #3) > (In reply to comment #2) > > What does "arp -n" show? > "arp -n" shows the correct arp entry. Can you please post full `arp -n` output? And then also please post output of `dig <ip_address_in_arp_output> PTR`. In my option this is DNS misconfiguration. I think you have following record in your 3.168.192.in-addr.arpa. zone: X.3.168.192.in-addr.arpa. IN PTR unused.

"arp -n " and "dig -x ip PTR" output file
# dig -x 192.168.5.1 PTR ;; ANSWER SECTION: 1.5.168.192.in-addr.arpa. 86134 IN PTR unused. means that 1.5.168.192.in-addr.arpa. is a PTR record pointing to DNS name "unused." Am I right Adam ?

Am I right Adam ? Right you are. Which means that arp behaves as expected... Thanks, closing per previous comment. |
