[Go-essp-tech] Report on wget behavior

[Karl Taylor]

Hi all,

I know everyone is working hard on things and that ESGis  evolving 
hourly, but here are some problems I encountered in trying to get the 
wget script to work:

1. For the Mac, you must use "snow leopard" OS 10.6 in order to run Java 
1.6.  Earlier operating systems (e.g., "leopard": 10.5.8) can only run 
Java 1.5, which is incompatible with what ESG needs to run MyProxy.  We 
need to warn users about this.

2.  For the Mac, even when I was able to download the certificates, when 
I tried to run the wget script, I got the errors copied at the bottom of 
this email.  [Also I've attached the wget script.]  I think Bob has 
already reported this error.

3.  I was unable to understand how to try the "other options" to run 
wget.  I read the following under "trouble shooting" after clicking on 
"Other options" to "obtain security credentials":

"Run the following two commands on your Unix system to launch MyProxyLogon:
wget 
http://cmip-gw.badc.rl.ac.uk/webstart/myProxyLogon/MyProxyLogon-ESG.jar 
-O $HOME/.esg/MyProxyLogon.jar
java -jar $HOME/.esg/MyProxyLogon.jar -u <username> -h <myproxy-server>  "

I presume that <username> is my ESGF username, but I have no idea what 
<myproxy-server> is.
Can I run this on a mac (terminal window)?  -- that's not what it says, 
but I wondered.
Don't you have to first download MyProxy something before executing 
these two commands?

4.  Somewhere we should indicate what the requirements are for 
successfully downloading and executing wget using the Web Start method 
of launching MYProxyLogon.  I think they include:
a) installation of java 1.6 (and if running on a mac, Mac 10.6 or higher).
b) Elimination of firewall protections against opening "non-standard" ports.
c) Web Start software installed and enabled on your browser.
d) wget installed.

We also need to indicate where one can get the required software.

On systems easily accessible by me only c) and d) were satisfied.  On a 
Linux system I successfully downloaded data after addressing b)  (The 
other requirements were aleady met.)

Note that perhaps a majority of mac users are still using Mac 10.5, so 
they will have a very difficult time.  [Of course pc folks running 
windows will be shut out.]  This is o.k. for now, I suppose.

Best regards,
Karl
