I've monitored the status of the arp table using "arp -n" and "cat /proc/net/arp" at the same time (for a long time, every 1 second).
The strange thing that I have found is that sometimes, in the "arp -n", the publishing entry (P flag) is missing, while in the "cat /proc/net/arp" it is always present. I have no idea why it happens, but I suppose (and hope :)) that if the entry is present in the "cat /proc/net/arp" output then the arp proxy behavious is ok.
Is it right? Antonio Arkadiusz Binder wrote:
and what shows #ip ro sh cache? It might be that you have not arp of some host who respond for icmp and arp's in case of some recieved icmp redirect packet. -----Original Message----- From: "gypsy"<[EMAIL PROTECTED]> Sent: 05-05-18 05:27:02 To: "Antonio Pinizzotto"<[EMAIL PROTECTED]> Cc: "[email protected]"<[email protected]> Subject: Re: [LARTC] problem with the "arp" command (using the pub flag) Antonio Pinizzotto wrote: > ___PROBLEM___> > The problems is that, sometimes, the second line (the one with the P> Flag in the "arp -n" output) desappears for some time and then appears > again... !!?> > Note.> Do you know if it is normal or if it could be a bug in "arp"? > I didn't verify if, when the second line is not present, the host A > continues to answer to ARP Request for 192.168.30.130 on eth0. > In other words I didn't verify if it's just a problem in the output (of > "arp -n" command) and not in the behaviour.> > Antonio You got Trouble, Antonio! I've been running for 2+ months with no "disappearing" PUB arps. arp -nworks flawlessly.Wondering: Could it be a bad NIC or cable?-- gypsy
