We currently run a public mirror (mirror.csclub.uwaterloo.ca) on sodium-benzoate. We are listed on the ResNet "don't count" list so downloading from our mirror will not count against one's ResNet quota. Requests to mirror a particular distribution or archive should be made to syscom@csclub.uwaterloo.ca.

Implementation Details
The mirroring is done by one of two scripts. Both are based on anonftpsync. Various cronjobs are scheduled to call one of these scripts.
csc-sync-debian
This is used to sync debian-style repositories. It's usage is:
csc-sync-debian local_dir rsync_host rsync_dir [trace_host [trace_dir]]
If trace_host is specified, then $rsync_dir/project/trace/$trace_host is checked to see if it has changed. If it has, a normal debian-style (two-pass) rsync is done.
csc-sync-standard
This is used to sync a tree in a general way. Like anonftpsync, it supports locking and logging. It's usage is:
csc-sync-standard local_dir rsync_host rsync_dir
Crontab
All cronjobs are listed in mirror's crontab. If csc-sync-debian is used, the cronjob is typically run bi-hourly. When using csc-sync-standard, the frequency of the cronjob is typically 12 hours. The crontab currently looks like this:

HTTP
We use Apache as our web server. Here's a snippet of the worker configuration:
<IfModule mpm_worker_module>
ServerLimit 32
ThreadLimit 64
StartServers 2
MaxClients 2048
MinSpareThreads 16
MaxSpareThreads 48
ThreadsPerChild 64
MaxRequestsPerChild 0
</IfModule>
We use the bwbar application to display current bandwidth in the footer of mirror pages.
We use mod_bw to ensure every connection is at least 100 KiB/s.
FTP
We use proftpd (standalone daemon) as our ftp server. To increase performance we disable DNS lookups in proftpd.conf:
UseReverseDNS off IdentLookups off
We also limit the amount of CPU/memory resources used (e.g. to minimize Globbing resources):
RLimitCPU session 10 RLimitMemory session 4096K
We allow a maximum of 200 concurrent ftp sessions:
MaxInstances 500 MaxClients 500
Rsync
We use rsyncd (standalone daemon). We disable compression and checksumming in rsyncd.conf:
dont compress = * refuse options = c delete
For ftp and rsync, the contents of /mirror/root/include/motd.msg are displayed when users connect.
