I'm running an arp -an on a Solaris 10 box. We're using IPMP. One of the systems is not able to see a host on the same network. The only difference between the two systems (one is having a problem, the other isn't) at least so far is the output of arp:
# arp -an | grep 224.55
e1000g5 10.109.224.55 255.255.255.255 o 00:01:d7:58:02:86
e1000g7 10.109.224.55 255.255.255.255 o 00:01:d7:58:02:86
The issue we're having is that 10.109.224.55 is the local DNS server. For some reason the first system is not seeing this IP and dropping to the backup DNS server.
Anyone have any ideas what the 'o' indicates? I did a "man arp" and it doesn't mention that flag.
e1000g7 is the standby interface so if traffic is trying to go that way, it'll time out (as it is) and go to the backup DNS.
Hi folks.

Dear all,
We are testing two of our servers for mq series connectivity. The scenario is, when one machine is shutting down it's services there are some scripts that do a dns update, which removes the ip address and relates it to the ip address of the other node on our dns server, and the update...

Hello,
I have 2 clients with Unix installed.
host1: eth0 (192.168.5.10) & eth1 (192.168.10.10)
host2: eth0 (192.168.10.20)
I've connected host1-eth1 to host2-eth0. host1-eth0 isn't connected.
I started 'tcpdump' on wonder that host2 got ARP requests for 192.168.5.10.
Any idea why host1... (2 Replies)

arp
ARP(8) BSD System Manager's Manual ARP(8)NAME
arp -- address resolution display and control
SYNOPSIS
arp [-n] hostname
arp [-nv] -a
arp [-v] -d -a
arp [-v] -d hostname [proxy]
arp -s hostname ether_addr [temp] [pub [proxy]]
arp -f filename
DESCRIPTION
The arp program displays and modifies the Internet-to-Ethernet address translation tables used by the address resolution protocol (arp(4)).
With no flags, the program displays the current ARP entry for hostname. The host may be specified by name or by number, using Internet dot
notation.
Available options:
-a The program displays all of the current ARP entries.
-d A super-user may delete an entry for the host called hostname with the -d flag. If the proxy keyword is specified, only the pub-
lished ``proxy only'' ARP entry for this host will be deleted. If used with -a instead of a hostname, it will delete all arp
entries.
-f Causes the file filename to be read and multiple entries to be set in the ARP tables. Entries in the file should be of the form
hostname ether_addr [temp] [pub]
with argument meanings as described below.
-n Show network addresses as numbers (normally arp attempts to display addresses symbolically).
-s hostname ether_addr
Create an ARP entry for the host called hostname with the Ethernet address ether_addr. The Ethernet address is given as six hex
bytes separated by colons. The entry will be permanent unless the word temp is given in the command. If the word pub is given, the
entry will be "published"; i.e., this system will act as an ARP server, responding to requests for hostname even though the host
address is not its own. If the word proxy is also given, the published entry will be a ``proxy only'' entry.
-v Display verbose information when adding or deleting ARP entries.

The arp command appeared in 4.3BSD.
