32     <body>
33 neysx 1.19
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.

44     <body>
45 neysx 1.19
46     <p>
47     The space requirements depend on whether you choose to run a "Full" mirror or a
48 klieber 1.22 "Distfiles only" mirror. Full mirrors require 90 gigabytes of disk space.
49     Distfiles only mirrors require 40 gigabytes of space.

57 neysx 1.19
58     <p>
59     We ask that you support a minimum of 15 and preferrably 30 concurrent user
60     connections.

68 neysx 1.19
69     <p>
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.

82 neysx 1.19
83     <p>
84     For new source mirror requests, the procedure will be as follows:
85     </p>
86    
87     <p>
88 jforman 1.20 Set up your server to rsync with ftp.ussg.iu.edu::gentoo-distfiles. Once you have a
89 neysx 1.19 complete mirror of that server, please file a bug report on bugs.gentoo.org
90     under the "rsync" category stating that you have a new mirror and wish it to be
91     added to the list of official mirrors. Please specify whether you wish to be a
92     "Full" mirror or "Distfiles only" mirror. Distfiles only mirrors will be
93     designated as such on the website.
94     </p>
95    
96     <p>
97     Full mirrors must carry the following directories (plus any directories that
98     get added in the future):
99     </p>
100    
101 cshields 1.16 <ul>
102     <li>/releases</li>
103     <li>/experimental</li>
104     <li>/distfiles</li>
105     <li>/snapshots</li>
106     <li>/grp</li>
107     </ul>
108 neysx 1.19
109     <p>
110     Distfiles only mirrors need to carry the following directories:
111     </p>
112    
113 cshields 1.16 <ul>
114     <li>/distfiles</li>
115     <li>/snapshots</li>
116     </ul>
117    
118 neysx 1.19 <p>
119     We will then verify that the mirror exists and we can connect to it properly.
120     Then, in the next 48-72 hours, we will determine if your mirror is syncing
121     correctly and in accordance with this policy.
122     </p>
123 klieber 1.1
124 neysx 1.19 <p>
125     If all steps went smoothly, we will then add you to our list of <uri
126     link="http://www.gentoo.org/main/en/mirrors.xml">download mirrors</uri> on the
127     main web site. We will also send you the login information for our private
128     master distfile mirror which is only available to official Gentoo Linux source
129     mirrors.
130     </p>
131    
132     <p>
133     Additionally, you, the mirror admin, will be requested to subscribe to the
134     gentoo-mirrors mailing list (low traffic) so that you can follow all issues
135     associated with source mirrors.

154     <section>
155     <title>Q: Who should I contact regarding new mirrors or to get my mirror added to the Gentoo web site?</title>
156     <body>
157 neysx 1.19
158     <p>
159     A: Please file a bug on bugs.gentoo.org under the rsync category.

165     <title>Q: Who should I contact regarding mirror issues and maintenance?</title>
166     <body>
167 neysx 1.19
168     <p>
169     A: Please file a bug on bugs.gentoo.org under the rsync category.

174 klieber 1.9 <section>
175     <title>Q: I run a private source mirror for my company. Can I still access the private master source mirror?</title>
176     <body>
177 neysx 1.19
178     <p>
179     A: Because our resources are limited, we need to ensure we allocate them in
180     such a way to provide the maximum amount of benefit to our users. As such, we
181     limit connections to our master rsync and distfile mirrors to public mirrors
182     only. Users are welcome to use our regular mirror system to establish a
183     private source mirror.

190 klieber 1.9 <title>Q: How do I find the mirror nearest to me?</title>
191 klieber 1.1 <body>
192 neysx 1.19
193     <p>
194     A: mirrorselect was designed to do this for you. If you haven't already run
195     <c>emerge mirrorselect</c>, then please do so. Then run: <c>mirrorselect</c>.
196     An ncurses-based menu will display allowing you to select a mirror close to
197     you.

203 klieber 1.11 <title>Q: I don't have that much disk space. Can I mirror part of the sources?</title>
204     <body>
205 neysx 1.19
206     <p>
207     A: Yes, if you are unable to mirror our full sources, you can elect to mirror
208     the following two directories only:
209     </p>
210    
211 klieber 1.11 <ul>
212     <li>/distfiles</li>
213     <li>/snapshots</li>
214     </ul>
215 neysx 1.19
216     <p>
217 klieber 1.22 These two directories will require approximately 40GB of space and you will be
218 neysx 1.19 listed on our site as a distfiles-only mirror.

230     /distfiles) if you wish.
