 This is critical for the security to restrict the number of people allowed access to the VOBOX. By default, only people with the VO SW manager role can log into the VO box. To change this configuration, refer to section on [#MappingofVOMSgroupsrolesintogrid-mapfile VOMS groups/roles mapping], but be sure you really need to allow other roles as it can give unwanted users access to privilege services.
 
-The configuration templates for the VOBOX enforce there is only one VO configured for acess to VOBOX specific services. This VO is declared using the `VOS` variable, as for other machine types. If you want to give other VOs access to the VOBOX for the management and operation of the VOBOX, you need to explicitly allow them using the variable `VOBOX_OPERATION_VOS`. This variable is a list of VOs considered as operation VOs. By default, this list is only VO `ops`. If the VOs listed in this variable are not listed in  `VOS`, they are automatically added.

+There are some other variables available to tune the VOBOX configuration but the default should generally be appropriate. The main ones are:
+ * `VOBOX_TCP_MAX_BUFFER_SIZE`: the maximum TCP buffer size to use. This is critical to reach good performances on high speed network. Default: 8388608.
+ * `VOBOX_TCP_MAX_BACKLOG`: another critical TCP congestion control parameter to reach high throughput and good performances. Default: 250000.
 
 In addition, most of the configuration variables available for the UI, in particular those related to gsissh server, apply for VOBOX too. In particular, it is generally necessary to [#CustomizingDefaultEnvironment define] the default MyProxy server (`MYPROXY_DEFAULT_SERVER`).
