113 | the chroot setting affects rsync's ability to look up the names of the |
114 | users and groups and what you can do about it. | |
115 | ||
116 | +dit(bf(--usermap=STRING, --groupmap=STRING)) These options allow you to | |
409bd73e WD |
117 | +specify users and groups that should be mapped to other values by the |
118 | +receiving side. The bf(STRING) is one or more bf(FROM):bf(TO) pairs of | |
119 | +values separated by commas. Any matching bf(FROM) value from the sender is | |
120 | +replaced with a bf(TO) value from the receiver. You may specify usernames | |
121 | +or user IDs for the bf(FROM) and bf(TO) values, and the bf(FROM) value may | |
122 | +also be a wild-card string, which will be matched against the sender's | |
f62e6e48 | 123 | +names (wild-cards do NOT match against ID numbers). For example: |
409bd73e | 124 | + |
f62e6e48 | 125 | +verb( --usermap=0:bin,wayne:admin,*:nobody --groupmap=usr:1,1:usr) |
409bd73e WD |
126 | + |
127 | +The first match in the list is the one that is used. You should not use | |
128 | +multiple options of the same type, but instead include all the user | |
129 | +mappings you need separated by commas to a single bf(--usermap) option, | |
130 | +and likewise for groups with the bf(--groupmap) option. | |
4122278d | 131 | + |
9405aad3 | 132 | +Note that the sender's name for the 0 user and group are not transmitted |
409bd73e WD |
133 | +to the receiver, so you should either match these values using a 0, or use |
134 | +the names in effect on the receiving side. All other bf(FROM) names match | |
9405aad3 WD |
135 | +those in use on the sending side. All bf(TO) names match those in use on |
136 | +the receiving side. | |
4122278d | 137 | + |
9405aad3 WD |
138 | +Any IDs that do not have name on the sending side are treaded as having an |
139 | +empty name for the purpose of matching. This allows them to be matched via | |
140 | +a "*" as well as an empty name mapping. For instance: | |
141 | + | |
142 | +verb( --usermap=:nobody --groupmap=*:nobody) | |
143 | + | |
144 | +When the bf(--numeric-ids) option is used,the sender does not send any | |
145 | +names, so all the IDs are treaded as having an empty name. This means that | |
146 | +you will need to specify numeric bf(FROM) values if you want to map these | |
147 | +nameless IDs to different values. | |
4122278d | 148 | + |
409bd73e WD |
149 | +For the bf(--usermap) option to have any effect, the bf(-o) (bf(--owner)) |
150 | +option must be used (or implied), and the receiver will need to be running | |
9405aad3 | 151 | +as a super-user (see also the bf(--fake-super) option). For the bf(--groupmap) |
409bd73e WD |
152 | +option to have any effect, the bf(-g) (bf(--groups)) option must be used |
153 | +(or implied), and the receiver will need to have permissions to set that | |
154 | +group. | |
4122278d WD |
155 | + |
156 | dit(bf(--timeout=TIMEOUT)) This option allows you to set a maximum I/O | |
157 | timeout in seconds. If no data is transferred for the specified time | |
158 | then rsync will exit. The default is 0, which means no timeout. | |
