<title>Minimum Bandwidth</title>

<p>

To properly host a source mirror, you should have a minimum of 5Mbps upstream
|
| 40 |
bandwidth. ADSL and cable connections do not generally make adequate
|
| 41 |
connections for distfile hosts due to their limited upstream performance.
|
| 42 |

<title>Minimum Disk Space</title>
|
| 48 |
<body>
|
| 49 |
|
| 50 |
<p>
|
| 51 |
The space requirements depend on whether you choose to run a "Full" mirror or a
|
| 52 |
"Distfiles only" mirror. Full mirrors require 90 GB of disk space. Distfiles
|
| 53 |
only mirrors require 40 GB of space.

<title>Minimum User Count</title>
|
| 60 |
<body>
|
| 61 |
|
| 62 |
<p>
|
| 63 |
We ask that you support a minimum of 15 and preferrably 30 concurrent user
|
| 64 |
connections.
|

<title>Update Frequency</title>
|

<body>
|
| 72 |
|
| 73 |
<p>
|
| 74 |
All mirrors must be synchronized every four hours, starting at midnight in your
|
| 75 |
local time zone. This helps distribute the load out over a period of time,
|
| 76 |
rather than having all mirrors synchronize at the same time.

|
| 85 |
<p>
|
| 86 |
Your mirror may not be added immediately to our listing and given access to the
|
| 87 |
private distribution point. We add mirrors on an as-needed basis so as not to
|
| 88 |
clutter up the listing, and to provide an adequate amount of high speed
|
| 89 |
mirrors. You are more than welcome to peek in #gentoo-mirrors on
|
| 90 |
irc.freenode.org and chat up to see the status of your mirror being added to
|
| 91 |
our official network.

<p>
|
| 104 |
For new source mirror requests, the procedure will be as follows:
|
| 105 |
</p>
|
| 106 |
|
| 107 |
<p>
|
| 108 |
Set up your server to rsync with ftp.ussg.iu.edu::gentoo-distfiles. Once you
|
| 109 |
have a complete mirror of that server, please file a bug report on <uri
|
| 110 |
link="http://bugs.gentoo.org/enter_bug.cgi?product=Mirrors">bugs.gentoo.org</uri>
|
| 111 |
under the <c>Mirrors</c> category stating that you have a new mirror and wish
|
| 112 |
it to be added to the list of official mirrors. Please specify whether you
|
| 113 |
wish to be a "Full" mirror or "Distfiles only" mirror. Distfiles
|
| 114 |
only mirrors will be designated as such on the website.
|
| 115 |
</p>
|
| 116 |
|
| 117 |
<p>
|
| 118 |
Full mirrors must carry the following directories (plus any directories that
|
| 119 |
get added in the future):
|
| 120 |
</p>
|
| 121 |
|
| 122 |
<ul>
|
| 123 |
<li>/releases</li>
|
| 124 |
<li>/experimental</li>
|
| 125 |
<li>/distfiles</li>
|
| 126 |
<li>/snapshots</li>
|
| 127 |
<li>/grp</li>
|
| 128 |
</ul>
|
| 129 |
|
| 130 |
<p>
|
| 131 |
Distfiles only mirrors need to carry the following directories:
|
| 132 |
</p>
|
| 133 |
|
| 134 |
<ul>
|
| 135 |
<li>/distfiles</li>
|
| 136 |
<li>/snapshots</li>
|
| 137 |
</ul>
|
| 138 |
|
| 139 |
<p>
|
| 140 |
We will then verify that the mirror exists and we can connect to it properly.
|
| 141 |
Then, in the next 48-72 hours, we will determine if your mirror is syncing
|
| 142 |
correctly and in accordance with this policy.
|
| 143 |
</p>
|
| 144 |
|
| 145 |
<p>
|
| 146 |
If all steps went smoothly, we will then add you to our list of <uri
|
| 147 |
link="/main/en/mirrors.xml">download mirrors</uri> on the main web site. We
|
| 148 |
will also send you the login information for our private master distfile mirror
|
| 149 |
which is only available to official Gentoo Linux source mirrors.
|
| 150 |
</p>
|
| 151 |
|
| 152 |
<p>
|
| 153 |
Additionally, you, the mirror admin, will be requested to subscribe to the
|
| 154 |
gentoo-mirrors mailing list (low traffic) so that you can follow all issues
|
| 155 |
associated with source mirrors.

Q: I run a private source mirror for my company. Can I still access the
|
| 201 |
private master source mirror?

</title>
|
| 203 |
<body>
|
| 204 |
|

<p>
|
| 206 |
A: Because our resources are limited, we need to ensure we allocate them in
|
| 207 |
such a way to provide the maximum amount of benefit to our users. As such, we
|
| 208 |
limit connections to our master rsync and distfile mirrors to public mirrors
|
| 209 |
only. Users are welcome to use our regular mirror system to establish a
|
| 210 |
private source mirror.

|
| 217 |
<body>
|

|

<p>
|
| 220 |
A: mirrorselect was designed to do this for you. If you haven't already run
|
| 221 |
<c>emerge mirrorselect</c>, then please do so. Then run: <c>mirrorselect</c>.
|
| 222 |
An ncurses-based menu will display allowing you to select a mirror close to
|
| 223 |
you.

Q: I don't have that much disk space. Can I mirror part of the sources?
|
| 231 |
</title>
|
| 232 |
<body>
|
| 233 |
|
| 234 |
<p>
|
| 235 |
A: Yes, if you are unable to mirror our full sources, you can elect to mirror
|
| 236 |
the following two directories only:
|
| 237 |
</p>
|
| 238 |
|
| 239 |
<ul>
|
| 240 |
<li>/distfiles</li>
|
| 241 |
<li>/snapshots</li>
|
| 242 |
</ul>
|
| 243 |
|
| 244 |
<p>
|
| 245 |
These two directories will require approximately 40GB of space and you will be
|
| 246 |
listed on our site as a distfiles-only mirror.

Q: Do I have to turn on Directory Indexing for directories served up via HTTP?
|
| 254 |
</title>
|
| 255 |
<body>
|
| 256 |
|
| 257 |
<p>
|
| 258 |
A: Directory Indexing is required for the /releases and /experimental
|
| 259 |
directories, but can be turned off for all other directories (including
|
| 260 |
/distfiles) if you wish.

<title>Q: Do I have to mirror historical? I mean, it is old releases.</title>
|
| 268 |
<body>
|
| 269 |
|
| 270 |
<p>
|
| 271 |
A: Of course not, it is quite a bit of data. In your rsync command, add
|
| 272 |
<path>--exclude=/releases/historical</path> to your rsync options. This will
|
| 273 |
exclude historical and save you quite a bit of space.
