Crossroads Load Balancer 2.00 (Default branch)
08-08-2008
Crossroads is a daemon running in user space, and features extensive configurability, polling of back ends using wake up calls, status reporting, many algorithms to select the 'right' back end for a request (and user-defined algorithms for very special cases), and much more. Crossroads is service-independent: it is usable for any TCP service, such as HTTP(S), SSH, SMTP, and database connections. In the case of HTTP balancing, Crossroads can provide session stickiness for back end processes that need sessions, but aren't session-aware of other back ends. Crossroads can be run as a stand-alone daemon or via inetd.License: GNU General Public License v3Changes:|

uucico(8) System Manager's Manual uucico(8) Name uucico - uucp file transfer daemon Syntax /usr/lib/uucp/uucico [ -f ] [ -r1 ] [ -s system ] [ -x# ] [ -X# ] Description The program is the daemon associated with the utility. The daemon is automatically run when requests are made or when polling occurs as specified in It performs the actual file transfer over the network. The program first calls up the destination system and login. After a successful login, a handshake takes place between the destination daemon process and the local daemon. The handshake determines if each daemon has permission to use the other's local resources. Both daemons then select the protocol that will be used to send and receive raw data. The local daemon searches the spool directories for job requests, builds a list of files to transfer, then begins transmitting files. The file transfer protocol ensures that each file is transmitted only once and also notifies the user if a file cannot be transferred. After the program transfers all the files, the destination site transfers files back to the local system. When both systems have completed their file transfers, the connection through the network is terminated. The output of follows the progress of the conversation. Debugging output from the slave is placed in the file in the spool directory at the remote site. The output is less meaningful than the unless the source code is available to help interpret the messages. Options -f Forces to start a conversation with a specified system, regardless of any previous connection status as provided by the files (system status). -r1 Puts into the master role. The slave mode is the default. -s system Designates the system to be contacted. -x# Sets the debugging level. The number sign (#) can have a value of 0 to 9. The higher the number, the more debugging output. No packet level debugging is printed. -X# Sets packet level debugging output. The number sign (#) can have a value of 0 to 9. The higher the number, the more packet level debugging output. Files See Also uucp(1c), uux(1c) Guide to the uucp Utility uucico(8)
