I don’t know if this file comes from clam or amavis-new, but….
It contains the comment and command:
# Run as a selected user (clamd must be started by root)
Is this conf file for clam or amavis?
As in /etc/clamd.conf we have:
# Run as another user (clamd must be started by root for this option to work)
# Default: don’t drop privileges User clam
# Initialize supplementary group access (clamd must be started by root).
# Default: no AllowSupplementaryGroups yes
Then in /etc/amavisd.conf (the real? conf file for amavis-new) in the Clamav section are comments:
# # Note: run clamd under the same user as amavisd, or run it under its own
# # uid such as clamav, add user clamav to the amavis group, and then add
# # AllowSupplementaryGroups to clamd.conf;
So is clam running under its user or amavis? Why is this last comment pointing to the ‘old’ clamav userid?
