I have bought from eBay a second hand Sun Fire V210 server and I'm really stumped at the lack of complete instructions on how to connect to it.
I don't have a Windows machine, I've only got Ubuntu and OS X computers. None of them have an old RS-232 port on them either.
In saying that, I have... (12 Replies)

Hey,
I have a V210 with a failed CPU fan.
The temperature is currently at 84C and I've been asked to wait a few weeks before replacing as its a production system and it cant be shut down yet.
Is it too hot? Do I risk killing the CPU at this temp?
Its been like this for a few weeks now... (5 Replies)

First post here!
I have a Sun V210 that I use occasionally for build testing things big-endian. I switched it on the other day, at it aint comin' up. I was wondering if anyone on this fine forum knows if it can be brought back from the dead.

arp
ARP(4) BSD Kernel Interfaces Manual ARP(4)NAME
arp -- Address Resolution Protocol
SYNOPSIS
pseudo-device ether
DESCRIPTION
The Address Resolution Protocol (ARP) is a protocol used to dynamically map between Internet host addresses and 10Mb/s Ethernet addresses.
It is used by all the 10Mb/s Ethernet interface drivers. It is not specific to Internet protocols or to 10Mb/s Ethernet, but this implemen-
tation currently supports only that combination.
ARP caches Internet-Ethernet address mappings. When an interface requests a mapping for an address not in the cache, ARP queues the message
which requires the mapping and broadcasts a message on the associated network requesting the address mapping. If a response is provided, the
new mapping is cached and any pending message is transmitted. ARP will queue at most one packet while waiting for a response to a mapping
request; only the most recently ``transmitted'' packet is kept. If the target host does not respond after several requests, the host is con-
sidered to be down for a short period (normally 20 seconds), allowing an error to be returned to transmission attempts during this interval.
The error is EHOSTDOWN for a non-responding destination host, and EHOSTUNREACH for a non-responding router.
The ARP cache is stored in the system routing table as dynamically-created host routes. The route to a directly-attached Ethernet network is
installed as a ``cloning'' route (one with the RTF_CLONING flag set), causing routes to individual hosts on that network to be created on
demand. These routes time out periodically (normally 20 minutes after validated; entries are not validated when not in use). An entry for a
host which is not responding is a ``reject'' route (one with the RTF_REJECT flag set).
ARP entries may be added, deleted or changed with the arp(8) utility. Manually-added entries may be temporary or permanent, and may be
``published'', in which case the system will respond to ARP requests for that host as if it were the target of the request.
In the past, ARP was used to negotiate the use of a trailer encapsulation. This is no longer supported.
ARP watches passively for hosts impersonating the local host (i.e. a host which responds to an ARP mapping request for the local host's
address).
DIAGNOSTICS
duplicate IP address %x!! sent from ethernet address: %x:%x:%x:%x:%x:%x. ARP has discovered another host on the local network which responds
to mapping requests for its own Internet address with a different Ethernet address, generally indicating that two hosts are attempting to use
the same Internet address.
