How old of a system did the original install come from? The reason I
mention is the thing I completely forgot about when upgrading my BackupPC
from Centos 8 Stream to Fedora Server 39 is the apache configuration:
# cat BackupPC.conf
<DirectoryMatch /usr/(share|libexec)/BackupPC/>
# BackupPC requires valid authentication in order for the web interface to
# function properly. One can view the web interface without authentication
# though all functionality is disabled.
#
# htpasswd -c /etc/BackupPC/apache.users yourusername
#
AuthType Basic
AuthUserFile /etc/BackupPC/apache.users
AuthName "BackupPC"
<IfModule mod_authz_core.c>
# Apache 2.4
<RequireAll>
Require valid-user
<RequireAny>
Require ip 192.168.1.0/255.255.255.0
</RequireAny>
</RequireAll>
</IfModule>
<IfModule !mod_authz_core.c>
# Apache 2.2
order deny,allow
deny from all
allow from 127.0.0.1
allow from ::1
require valid-user
</IfModule>
</DirectoryMatch>
Alias /BackupPC/images /usr/share/BackupPC/html/
ScriptAlias /BackupPC /usr/libexec/BackupPC/BackupPC_Admin
ScriptAlias /backuppc /usr/libexec/BackupPC/BackupPC_Admin
The key is I had to add Require ip xx.xxx.xxx.xxx/255.255.255.0 because by
default it only allows connections from the host.
Thanks,
Richard
