Mike,
I think the fix to your opd problem is to define an environmental
variable with the name "http_proxy" and set it to your web proxy, i.e.
export http_proxy=http://squid.my.place:3128/
and then it should work. Have a look at the man LWP::UserAgent in the
section on env_proxy for some more examples. Note, you define these
variable in your environment, not in the perl scripts. This is all
similar to what is used by lynx and a number of other command line
browsers.
As to how to install rpm updates, I haven't read the documentation
recently, but the easiest way I've found is to install them directly
onto the nodes, i.e. put them in a common place (e.g. my home directory)
and then as root do:
cexec rpm -Fvh ~frank/*.rpm
which will install them everywhere. Once I'm sure it is okay, then I
run a final step to update the image directory on the head node with:
rpm -Fvh --root /var/lib/systemimage/images/XXX/ ~frank/*.rpm
However, you as with other updates, you need to be very careful with
certain type of changes, especially kernel updates. If you do want to
update the kernel through rpm you also need to modify the
systemconfigurator scripts with the new names and the create initrd
files with the correct names. I've attached a little script I used last
time I did such changes.
