# udp\_driver\_envs(3)

The udp driver uses the following environment variables.

## NAME

Env Variables - The udp driver uses the following environment variables.

- •

  GLOBUS\_HOSTNAME Used when setting the hostname in the contact string

- •

  GLOBUS\_UDP\_PORT\_RANGE Used to restrict the port the udp socket binds to

- •

  GLOBUS\_XIO\_SYSTEM\_DEBUG Available if using a debug build. See globus\_debug.h for format. The UDP driver uses globus\_xio\_system (along with the File and TCP drivers) which defines the following levels: TRACE for all function call tracing, DATA for data read and written counts, INFO for some special events, and RAW which dumps the raw buffers actually read or written. This can contain binary data, so be careful when you enable it.
