31 <title>Minimum Bandwidth</title>
32 <body>
33
34 <p>
35 To properly host a source mirror, you should have a minimum of 5Mbps upstream
36 bandwidth. ADSL and cable connections do not generally make adequate
37 connections for distfile hosts due to their limited upstream performance.

43 <title>Minimum Disk Space</title>
44 <body>
45
46 <p>
47 The space requirements depend on whether you choose to run a "Full" mirror or a
48 "Distfiles only" mirror. Full mirrors require 90 GB of disk space. Distfiles
49 only mirrors require 40 GB of space.

55 <title>Minimum User Count</title>
56 <body>
57
58 <p>
59 We ask that you support a minimum of 15 and preferrably 30 concurrent user
60 connections.

70 All mirrors must be synchronized every four hours, starting at midnight in your
71 local time zone. This helps distribute the load out over a period of time,
72 rather than having all mirrors synchronize at the same time.

78 <title>Mirror Needs</title>
79 <body>
80 <p>
81 Your mirror may not be added immediately to our listing and given access to the private distribution point. We add mirrors
82 on an as-needed basis so as not to clutter up the listing, and to provide an adequate amount of high speed mirrors. You are more than
83 welcome to peek in #gentoo-mirrors on irc.freenode.org and chat up to see the status of your mirror being added to our official network.

93
94 <p>
95 For new source mirror requests, the procedure will be as follows:
96 </p>
97
98 <p>
99 Set up your server to rsync with ftp.ussg.iu.edu::gentoo-distfiles. Once you
100 have a complete mirror of that server, please file a bug report on
101 bugs.gentoo.org under the "rsync" category stating that you have a new mirror
102 and wish it to be added to the list of official mirrors. Please specify
103 whether you wish to be a "Full" mirror or "Distfiles only" mirror. Distfiles
104 only mirrors will be designated as such on the website.
105 </p>
106
107 <p>
108 Full mirrors must carry the following directories (plus any directories that
109 get added in the future):
110 </p>
111
112 <ul>
113 <li>/releases</li>
114 <li>/experimental</li>
115 <li>/distfiles</li>
116 <li>/snapshots</li>
117 <li>/grp</li>
118 </ul>
119
120 <p>
121 Distfiles only mirrors need to carry the following directories:
122 </p>
123
124 <ul>
125 <li>/distfiles</li>
126 <li>/snapshots</li>
127 </ul>
128
129 <p>
130 We will then verify that the mirror exists and we can connect to it properly.
131 Then, in the next 48-72 hours, we will determine if your mirror is syncing
132 correctly and in accordance with this policy.
133 </p>
134
135 <p>
136 If all steps went smoothly, we will then add you to our list of <uri
137 link="/main/en/mirrors.xml">download mirrors</uri> on the main web site. We
138 will also send you the login information for our private master distfile mirror
139 which is only available to official Gentoo Linux source mirrors.
140 </p>
141
142 <p>
143 Additionally, you, the mirror admin, will be requested to subscribe to the
144 gentoo-mirrors mailing list (low traffic) so that you can follow all issues
145 associated with source mirrors.
146 </p>
147
148 <note>
149 Thanks for helping out Gentoo Linux users and developers! :) For any mirror
150 administration issues or problems, please contact <mail
151 link="mirror-admin@gentoo.org">mirror-admin@gentoo.org</mail>.
152 </note>
153
154 <warn>
155 Do NOT email mirror-admin@gentoo.org for mirror requests, please file a bug. It makes mirror tracking easier on us.

164 <section>
165 <title>Q: Who should I contact regarding new mirrors or to get my mirror added to the Gentoo web site?</title>
166 <body>
167
168 <p>
169 A: Please file a bug on bugs.gentoo.org under the rsync category.

174 <section>
175 <title>Q: Who should I contact regarding mirror issues and maintenance?</title>
176 <body>
177
178 <p>
179 A: Please file a bug on bugs.gentoo.org under the rsync category.

184 <section>
185 <title>Q: I run a private source mirror for my company. Can I still access the private master source mirror?</title>
186 <body>
187
188 <p>
189 A: Because our resources are limited, we need to ensure we allocate them in
190 such a way to provide the maximum amount of benefit to our users. As such, we
191 limit connections to our master rsync and distfile mirrors to public mirrors
192 only. Users are welcome to use our regular mirror system to establish a
193 private source mirror.

199 <section>
200 <title>Q: How do I find the mirror nearest to me?</title>
201 <body>
202
203 <p>
204 A: mirrorselect was designed to do this for you. If you haven't already run
205 <c>emerge mirrorselect</c>, then please do so. Then run: <c>mirrorselect</c>.
206 An ncurses-based menu will display allowing you to select a mirror close to
207 you.
208 </p>
209
210 </body>
211 </section>
212 <section>
213 <title>Q: I don't have that much disk space. Can I mirror part of the sources?</title>
214 <body>
215
216 <p>
217 A: Yes, if you are unable to mirror our full sources, you can elect to mirror
218 the following two directories only:
219 </p>
220
221 <ul>
222 <li>/distfiles</li>
223 <li>/snapshots</li>
224 </ul>
225
226 <p>
227 These two directories will require approximately 40GB of space and you will be
228 listed on our site as a distfiles-only mirror.
229 </p>
230
231 </body>
232 </section>
233 <section>
234 <title>Q: Do I have to turn on Directory Indexing for directories served up via HTTP?</title>
235 <body>
236
237 <p>
238 A: Directory Indexing is required for the /releases and /experimental
239 directories, but can be turned off for all other directories (including
240 /distfiles) if you wish.
241 </p>
242 </body>
243 </section>
244
245 <section>
246 <title>Q: Do I have to mirror historical? I mean, it is old releases.</title>
247 <body>
248
249 <p>
250 A: Of course not, it is quite a bit of data. In your rsync command, add
251 <path>--exclude=/releases/historical</path> to your rsync options. This will
252 exclude historical and save you quite a bit of space.
