Yum using proxy that requires authentication and a Password that contains the two characters \/ fails normally I can get yum to work with a proxy that requires authentication when required by doing something like http_proxy=http://<my username>:<my password>@<proxy server>:<proxy server port> export http_proxy or by filling in the appropriate information in yum.conf. But if the password contains the characters \/ this does not work. I have tried quoting the password in various ways none seem to work eg export http_proxy=\/alid at proxy.example.com:80 export http_proxy='\/alid at proxy.example.com:80' export http_proxy="\/alid at proxy.example.com:80" export http_proxy=\\\/alid at proxy.example.com:80 Anyone have any ideas for a work around to this that doesn't involve changing the password or modifying the proxy config ? I have tried reporting this as http://bugs.centos.org/view.php?id=4123 but mantisbt presents the information I submitted in a way I didn't expect. If anyone can tell me how to modify the bug report to look the way I expected please let me know.
