Clear cache on SUSE Manager Proxy

This document (7018416) is provided subject to the disclaimer at the end of this document.

Environment

SUSE Manager 3
SUSE Manager 2.1

Situation

SUSE Manager Proxy is a way to:
- Work around DMZs
- Save bandwidth via RPM caching
- Alleviate a little bit of the computational load to the SUSE Manager server via XMLRPC API response caching.

In some situations (e.g. disk space problems, digest verification issues reported by zypper), it might be desired to flush the cache in the Proxy.

Resolution

Please follow the following procedure in the Proxy. Take into account that during the time the Proxy is stopped, the clients behind it won't have access to the SUSE Manager (and hence, neither to patches and remote commands). This should be a pretty fast procedure though:

spacewalk-proxy stop
rm -rf  /var/cache/squid/*
squid -z -N
spacewalk-proxy start

Additional Information

Repository digest verification issue reported by zypper:

Accepting packages with wrong checksums can lead to a corrupted system and in extreme cases even to a system compromise.

However if you made certain that the file with checksum 'bca6..' is secure, correct
and should be used within this operation, enter the first 4 characters of the checksum
to unblock using this file on your own risk. Empty input will discard the file.

Unblock or discard? [bca6/? shows all options] (discard):
