-Description: High performance ADC p2p hub
- uhub is a high performance peer-to-peer hub for the ADC network.
- Its low memory footprint allows it to handle several thousand users on
- high-end servers, or a small private hub on embedded hardware.
- .
- Key features:
-  - High performance and low memory usage
-  - IPv4 and IPv6 support
-  - Experimental SSL support (optional)
-  - Advanced access control support
-  - Easy configuration

 Simply, run:

-If you are planning to more than 1024 users on hub, you must increase the max number of file descriptors allowed.
-This limit needs to be higher than the configured max_users in uhub.conf.
-
-In linux can add the following lines to /etc/security/limits.conf (allows for ~4000 users)

-%description
-uhub is a high performance peer-to-peer hub for the ADC network.
-Its low memory footprint allows it to handle several thousand users on
-high-end servers, or a small private hub on embedded hardware.
-
-Key features:
-- High performance and low memory usage
-- IPv4 and IPv6 support
-- Experimental SSL support (optional)
-- Advanced access control support
-- Easy configuration
