[. . . ] Therefore, you may have to experiment with various options to achieve a functional configuration. IMPORTANT: Remote Access Settings By default, the cupsd only listens on internal network interfaces (localhost). When setting up a CUPS network server you need to adjust the Listen directive in /etc/cups/cupsd. conf to listen to the outer network. CUPS supports the socket, LPD, IPP, and smb protocols. Printer Operation 447 socket Socket refers to a connection in which the data is sent to an Internet socket without first performing a data handshake. Some of the socket port numbers that are commonly used are 9100 or 35. The device URI (uniform resource identifier) syntax is socket://IP. of. the. printer:port, for example, socket://192. 168. 2. 202:9100/. LPD (Line Printer Daemon) The proven LPD protocol is described in RFC 1179. Under this protocol, some job-related data, such as the ID of the printer queue, is sent before the actual print data is sent. Therefore, a printer queue must be specified when configuring the LPD protocol for the data transmission. The implementations of diverse printer manufacturers are flexible enough to accept any name as the printer queue. If necessary, the printer manual should indicate what name to use. LPT, LPT1, LP1, or similar names are often used. An LPD queue can also be configured on a different Linux or Unix host in the CUPS system. The port number for an LPD service is 515. An example device URI is lpd://192. 168. 2. 202/LPT1. IPP (Internet Printing Protocol) IPP is a relatively new (1999) protocol based on the HTTP protocol. With IPP, more job-related data is transmitted than with the other protocols. CUPS uses IPP for internal data transmission. This is the preferred protocol for a forwarding queue between two CUPS servers. The name of the print queue is necessary to configure IPP correctly. Example device URIs are ipp://192. 168. 2. 202/ps and ipp://192. 168. 2. 202/printers/ps. SMB (Windows Share) CUPS also supports printing on printers connected to Windows shares. [. . . ] The directory /usr/bin contains the vi editor, find, less, and ssh. To see the system messages, either use the command dmesg or view the file /var/ log/messages. Checking and Manipulating Configuration Files As an example for a configuration that might be fixed using the rescue system, imagine you have a broken configuration file that prevents the system from booting properly. You can fix this using the rescue system. To manipulate a configuration file, proceed as follows: 1 Start the rescue system using one of the methods described above. [. . . ]
