I know everyone is working hard on things and that ESG is evolving hourly, but here are some problems I encountered in trying to get the wget script to work:<br>
<br>
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.<br>
<br>
</font></span></blockquote><span style="font-size:11pt"><font face="Calibri, Verdana, Helvetica, Arial"> Assuming there are no 1.6 specific features, this is mostly likely just recompiling for 1.5. This should be really easy to solve.<br>
</font></span></blockquote><span style="font-size:11pt"><font face="Calibri, Verdana, Helvetica, Arial"><br>
Agreed. Neill indicated that 1.5 was what he used to compile this, so we shouldn't see any 1.6 dependencies. I just suggested on a separate thread that he verify this. Please let me know if you see any issues with using 1.5.<br>

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.<br>
<br>
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": <br>
<br>
"Run the following two commands on your Unix system to launch MyProxyLogon:<br>
wget <a href="http://cmip-gw.badc.rl.ac.uk/webstart/myProxyLogon/MyProxyLogon-ESG.jar">http://cmip-gw.badc.rl.ac.uk/webstart/myProxyLogon/MyProxyLogon-ESG.jar</a> -O $HOME/.esg/MyProxyLogon.jar<br>
java -jar $HOME/.esg/MyProxyLogon.jar -u <username> -h <myproxy-server> "<br>
<br>
I presume that <username> is my ESGF username, but I have no idea what <myproxy-server> is. <br>
Can I run this on a mac (terminal window)? -- that's not what it says, but I wondered.<br>
Don't you have to first download MyProxy something before executing these two commands?<br>
</font></span></blockquote></blockquote><span style="font-size:11pt"><font face="Calibri, Verdana, Helvetica, Arial"><br>
The first wget command you pasted above downloads the executable for the MyProxy client. This is the same as what the WebStart executes.<br>
<br>
On the <myproxy-server> value, it maybe worth displaying this on the Gateway for a user to copy/paste. It is auto-populated when WebStart works, so that information should be available.<br>
<br>

<br>
</font></span><blockquote><blockquote><span style="font-size:11pt"><font face="Times New Roman"><br>
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:<br>
a) installation of java 1.6 (and if running on a mac, Mac 10.6 or higher).<br>
b) Elimination of firewall protections against opening "non-standard" ports.<br>
c) Web Start software installed and enabled on your browser.<br>
d) wget installed.<br>
<br>
We also need to indicate where one can get the required software.<br>
<br>
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.)<br>
<br>
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.<br>
<br>
