Revision as of 18:07, 24 February 2010

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.

Proposed Archives to Mirror

  • Mandriva (774 GiB)
  • OpenBSD (209 GiB)
  • NetBSD (340 GiB)
  • PCLinuxOS

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:

# m  h     dom mon dow command

# make torrents
  */10 *  *   *   *     /home/mirror/bin/make-torrents > /dev/null 2> /dev/null

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.
