Mirror

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. We also have a bandwidth graph you can look at.

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.
