Hope this works ...................................


worked for me in FC7


I resolved the problem using percent encoding. As my FULL email address is my username, the above format would expand as below, with two '@'s, so yum would treat as password, which would fail.


I encoded the first '@' as '%40', which worked. I specified the http_proxy and ftp_proxy variables in /etc/bashrc and exported them as follows:

http_proxy= r

Yum works fine. But Yumex doesnt, as it relies on /etc/yum.conf, which does NOT have the proxy information. If proxy is mentioned in /etc/yum.conf, it gives non-numeric port error. And Yumex probably doesnt handle either two '@'s or percent encoding in URL, when declared in it's own configuration.

If someone's proxy username or password contains any special characters, percent encoding might work.

hi infoplateform,

I did not understand your explanation and was not able to correlate this to ISA 2006.
can you try creating new firewall access policy that allow the access from your computer ip address to external with all outbound traffic and see if that resolve your issue, also make sure when you test the rule that your using the correct rule while trying to access the website.
