How not to install fibre links between data centres!
Hi Folks,
A couple of years ago we had to replace the core switches between two of our data centres, a simple task for the most part - these new switches would be state of the art Cisco Catalyst units.
The link between the two sites was a dark fibre, with 8Gb bandwidth running full duplex over a redundant cable pair. It was quite a surprise when we started to tidy up the cables to find this - see the attached images.
The cables comprised two male to male cables, with the ends joined with Bluetack. I'm amazed that it worked for so long. - Actually I'm amazed it worked at all!
hi. I am newbie in Unix. I wanted to install Free BSD 5.2.1 to my computer which winXp was already installed. But i couldn't.
I chose Standard. Then it said you are going to use dos style fdisk partitioning. Then a window displayed begining like this.

Hello,
I have two systems that are being prepared to be SAN attached ..
can anyone tell me any specific checks I should perform prior to the cards being installed...
I am aware of firmware / OS level and relevant drivers, is there anything else?
thanks

We will be buying new Xeon E5-based servers for our datacenter and were wondering which Fibre Channel host bus adapters we should select for these. The choices are Emulex or QLogic (8Gb FC HBAs). Anybody have any recommendations on which is the better choice?
Thanks in advance. (1 Reply)
Hi guys,
I've been trying to tackle this issue for days and I'm stumped. Hopefully someone can give more light on what else I can do.
I have a p7 series box, with dual VIOS and 10 lpars and everything was working fine until I had to move the box to another location in the data centre. Ensured... (16 Replies)

rancid(1) General Commands Manual rancid(1)NAME
rancid - Cisco configuration filter
SYNOPSIS
rancid [-dlV] (-f filename | hostname)
DESCRIPTION
rancid is a perl(1) script which uses the login scripts (see clogin(1)) to login to a device, execute commands to display the
configuration, etc, then filters the output for formatting, security, and so on. rancid's product is a file with the name of it's last
argument plus the suffix .new. For example, hostname.new.
There are complementary scripts for other platforms and/or manufacturers that are supported by rancid(1). Briefly, these are:
agmrancid Cisco Anomaly Guard Module (AGM)
arancid Alteon WebOS switches
arrancid Arista Networks devices
brancid Bay Networks (nortel)

cssrancid Cisco content services switches

rrancid Redback
srancid SMC switch (some Dell OEMs)
trancid Netopia sDSL/T1 routers
tntrancid Lucent TNT
xrancid Extreme switches
xrrancid Cisco IOS-XR boxes
zrancid Zebra routing software
The command-line options are as follows:
-V Prints package name and version strings.
-d Display debugging information.
-l Display somewhat less debugging information.
-f rancid should interpret the next argument as a filename which contains the output it would normally collect from the device (
hostname) with clogin(1).

Cisco IOS offers a DHCP server that maintains a text database which can be stored remotely or on local storage. If stored locally, the
file changes constantly and causes constant diffs from rancid. If this file's name ('ip dhcp database') matches the regex
dhcp_[^[:space:].].txt, it will be filtered.
For Catalyst switches running CatOS, type cat5, the prompt must end with '>'. clogin(1) looks for '>' to determine when a login is
successful. For example:
cat5k>
cat5k> enable
Password:
cat5k> (enable)
rancid works on Cisco Catalyst 1900 series switches that are running Enterprise Edition software. This software provides a menu at
connection time that allows a command line interface to be used by entering 'K' at the prompt.
