It seems you need to restart the backup server after you add new unix
hosts. I added some hosts at the start of the week and after that all the
backups started failing with

"The connection to the data backup has been lost"

This happened for both existing (and working unix agents) and the new ones
I defined.

It took a little while to figure this out. At first I thought it might be
firewall related but looking at the network traffic showed that wasn't the
case. The debug output of agent.be (see agent.be -help) wasn't all that
useful and seemed to indicate normal operation.

After installing the new free VMware Server product I couldn't get the
vmware-mui-distrib tarball to install. It kept aborting with the message
"Failure" after saying it detected an previous install of vmware. Duh!, I
had put it there.

The previous install wasn't actually the problem though. I found the
[limited instrux for the new release|http://www.vmware.com/support/server/doc/releasenotes_server_beta.html#install]
and the said make sure libdb.so.3 is installed, which comes in the
compat-db rpm, btw. I installed it, still no luck.

Looking at the perl code it seemed to be looking for a previous install of

Need a server cert that has no password. Commands are:

(1) change directory into the grid-security directory: cd /etc/grid-security

(2) Generate the server key (with password): openssl genrsa -des3 -out server.key 1024

(3) Generate certificate *without a password*: openssl rsa -in server.key -out server.pem

(4) Create CSR (Certificate Signing Request) to affirm that the server key is valid. The server.pem is used in place of server.key as we don’t require a password:
openssl req -new -key server.pem -out server.csr

The information you are about to be asked to enter information will be incorporated into your certificate request as the Distinguished Name or a DN of the signed cert. [ If you enter ‘.’, the field will be left blank ]

This demos starts at the myVocs homepage: http://myvocs.org.

The point of starting here is to approach use of the tools from the perspective of a current and active VO participant. While you may not be that kind of user today, you can quickly become that user.

In essence, this is the type of user most of us are today, when it comes to the Internet. If we are interested in finding something, we rarely expect to be able to browse to the data from a directory of Internet catagories, like we did in the early days of the Internet with Yahoo!. For a new Internet user that doesn't know what's out there, Yahoo!'s catagories are useful. For an experienced user, you just want the search bar. Google figured that out and simplied their UI accordingly. You go to Google's search site expecting to type in your search and access the content of interest by browsing off the results our your search command.

!UPDATE: May 17, 2006
Two recent presentations have been given that provide an overview of myVocs and the scope of the technology and project. The first as at the [Spring 2006 Interent2 Member Meeting|http://grid.ncsa.uiuc.edu/presentations/i2mm-myvocs-gridshib-april06.ppt] in April and discussed our collaboration with the GridShib project and the second was given at the [TERENA 2006 conference in May|http://www.terena.nl/events/tnc2006/programme/presentations/show.php?pres_id=206]. This latter presentation is a good overview of the goals and architecture of myVocs. More updates to come.

answers to technical issues. we'll try to bring clarity to the developer
by focusing on the issues that are within our control and not getting
distracted with organizational issues. it's not that this issues are
unimportant in a deploy it's just that we want to look at the technology
and identify what is possible. it will be easiest to do this by
controlling the namespace of attributes in a way that is common in
homogenous system environments.

while i'm thinking about this. it's best not to use a javascript post to
enable webiso on a legacy app. this makes it hard to go directly to
specific urls in the legacy app. for webiso/vosp to work well it is best
to present a uniform namespace to the world and simply have restricted
areas in the namespace trigger the permissions checks. while the "touch
this java script page to generate a post to log the user in" works ok it
doesn't supply this type of namespace. all access to that subtree will
need to be through that javascript login post. this will prevent direct

You might come across this error while installing Trac:
