globus-ws is on now (ng2.auckland.ac.nz)

To install hostcert I used a procedure from:
http://www.vpac.org/twiki/bin/view/APACgrid/HostCertRequestAPAC

globus-ws requires /etc/grid-cequirity/containercert.pem
I've created copies:
cp /etc/grid-cequirity/hostcert.pem /etc/grid-cequirity/containercert.pem
cp /etc/grid-cequirity/hostcert_request.pem /etc/grid-cequirity/containercert_request.pem
cp /etc/grid-cequirity/hostkey.pem /etc/grid-cequirity/containerkey.pem

Owner of those files is daemon:

-rw-r--r-- 1 daemon daemon 2630 May 21 00:02 containercert.pem
-rw-r--r-- 1 daemon daemon 1770 May 21 00:03 containercert_request.pem
-r-------- 1 daemon daemon 1679 May 21 00:03 containerkey.pem

To check the certificate use a command:

openssl verify -CApath /etc/grid-security/certificates /etc/grid-security/containercert.pem

services.bestgrid.org

Established services on this host are:
  1. rsync
  2. mail server (under construction)
Planned services are:
  1. Subversion server

tar: Removing leading '/' from member names

To eliminate this message while creating an archive file with tar use the following syntax:

> tar cj -C / var/www > backup.tar.bz2

instead of

> tar cjf backup.tar.bz2 /var/www

Xen's VMs and IPs

In case to provide separate physical network interfaces for each BestGrid VM we need two IPs for each VM. One IP is for a bridge between NIC and VM and another one is for VM itself.

So to provide low IPs (189.2,3,4,5,6) for BeSTGrid GateWay VMs I need to swap NIC IPs to 189.38-42 range.

Unfortunately I have to state that our IP pool is over now. There are only two spare IPs - 189.37 and 189.43.

I'm going to start swap today after lunch.

Is it better than paper and simple notebook?

I try to follow my colleague Anton Gerdelan to keep a blog about my problems and achievements instead of to write then into a paper notebook. May be it's better... The bad thing is I can't keep here passwords for my stuff :)

But it's possible to keep it private... Hm... Anyway that's unsecured way to keep passwords here even in a private blog.
