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...

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:

About a week ago a customer hooked up a wireless router backwards to our network, causing it to serve incorrect DHCP addresses to some of them. Our networks are mostly statically assigned so this didn't cause as much damage as it might have, but now, over a week later, I still have incomplete... (1 Reply)
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)
A customer appears to have drastically misunderstood our instructions for connecting to our WAN. He set his PC IP address to the same as one of the bridges. :mad: :wall: This caused much confusion on the network, to put it mildly. He called to complain about the poor performance of the network... (13 Replies)
Hello,
I am setting up a new RedHat server with two network interfaces.
These interfaces are on different subnets, and connected to the same firewall.
I'm trying to reach a remote IP.
It works fine from the first interface.
The second interface however, is making ARP requests instead of... (0 Replies)

arp
arp(1M) System Administration Commands arp(1M)NAME
arp - address resolution display and control
SYNOPSIS
arp hostname
arp -a [-n]
arp -d hostname
arp -f filename
arp -s hostname ether_address [temp] [pub] [trail]
DESCRIPTION
The arp program displays and modifies the Internet-to-MAC address translation tables used by the address resolution protocol (see arp(7P)).
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.
OPTIONS -a Display all of the current ARP entries. The definition for the flags in the table are:
M Mapping; only used for the multicast entry for 224.0.0.0
P Publish; includes IP address for the machine and the addresses that have explicitly been added by the -s option. ARP will
respond to ARP requests for this address.
S Static; not learned for the ARP protocol.
U Unresolved; waiting for ARP response.
You can use the -n option with the -a option to disable the automatic numeric IP address-to-name translation. Use arp -an or arp
-na to display numeric IP addresses.
-d Delete an entry for the host called hostname. This option may only be used by the super-user.
-f Read the file named filename and set multiple entries in the ARP tables. Entries in the file should be of the form:
hostname MACaddress [temp] [pub] [trail]
See the -s option for argument definitions.
-s Create an ARP entry for the host called hostname with the MAC address MACaddress. For example, an Ethernet address is given as
six hexadecimal 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. For instance, this system will respond to ARP requests for hostname even though the
hostname is not its own. The word trail indicates that trailer encapsulations may be sent to this host. arp -s can be used for a
limited form of proxy ARP when a host on one of the directly attached networks is not physically present on the subnet. Another
machine can then be configured to respond to ARP requests using arp -s. This is useful in certain SLIP configurations.
