Hi all,
I have some issue with OEL 6.1 YUM proxy.

*[root@rac1 tmp]# uname -a*

In OEL5.7 this works fine without any problem. I think this related to OEL6.1, maybe YUM does not understand proxy, my password for proxy starting with @$ but I changed my password and
output is changed to

*[root@rac1 tmp]# yum update*
http://public-yum.oracle.com/repo/OracleLinux/OL6/0/base/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 407"
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: ol6_ga_base. Please verify its path and try again

If anyone can help me please reply.

./thanks
