MyProxy? Changes

Overview

• To move myproxy hostname from apac to arcs domain.
• This can be done without any change to the clients, although it would be nice to set everyone up using the ARCS domain in their clients.
• Successfully tested creating a proxy on old myproxy, copying it to new one and downloading - 10/6

Plan

Stage 1

• Set up myproxy2.arcs.org.au - DONE
• Test - DONE, ready to go live
• Change ARCS DNS records to point myproxy.arcs.org.au, myproxy1.arcs.org.au, myproxy2.arcs.org.au all to ->myproxy2.arcs.org.au
• Change APAC DNS records shown below
• Test

Stage 2

• set up myproxy1.arcs.org.au at Queensland
• Test
• Set up unison to sync the data dirs
• Test
• Change ARCS DNS records as shown below

DNS Changes

INITIAL ARCS RECORDS (Stage 1)

myproxy        A          IP ADDRESS 2

myproxy1       A          IP ADDRESS 2

myproxy2       A          IP ADDRESS 2

Final ARCS DNS RECORDS (stage 2)

myproxy        A          IP ADDRESS 1
               A          IP ADDRESS 2

myproxy1       A          IP ADDRESS 1

myproxy2       A          IP ADDRESS 2

APAC DNS RECORDS

myproxy      CNAME    myproxy.arcs.org.au
myproxy1     CNAME    myproxy1.arcs.org.au
myproxy2     CNAME    myproxy2.arcs.org.au

Things that Grid Admins need to do

Command line clients

Command line client - myproxy-logon etc. uses an enviroment variable to determine the server to speak to You can check this by doing

env | grep MYPROXY

This needs to be myproxy.arcs.org.au. To change this you need to change where this is being set. This can be changed now.

Other tools that use MyProxy?

Need to change the host in their code. This has already been done on grisu and can be done now.

If it breaks?

• Leave the old myproxy machines running after the change
• Change the DNS records back
