For more pattern replacements see Changer-Configuration-File (18)."`
helps__26=`TN_ "If you don't have a cartridge handling system (robot), a human maintainer must put the appropriate cartridge into the tape device. If you supply a mail program, an e-mail is sent to the user given here, which informs him, that and which cartridge (by number) must be put into the tape device. If a timespan is configured, after that an automatic e-mail should be sent due to an unaccessible tape device, it is directed to this user."`
helps__27=`TN_ "The mail program used to send messages to a human maintainer. This is done, whenever another cartridge must be put into the tape device and it can't be done automatically (by a robot or whatever). If you don't want to type the username again here, you can instead write %u . The pattern %U will be replaced with the login name of a current user on the client side, %H with the name of the client host. If none could be figured out, the entire word containing %U or %H is deleted from the command. For more pattern replacements see Changer-Configuration-File (18). If you don't want mails to be sent, you may instead supply any other command, that reads the standard input and does something reasonable with it, e.g. redirects it to the console:  cat > /dev/console"`

If the first word of this entry is starting with @, then logging is directed to the syslog as well. If there are characters immediately following the @, this word is used as the syslog identifier, otherwise the identifier is afbackup. If writing to the syslog is configured, the rest of the entry is used as additional logging file, if present. For pattern replacements see Changer-Configuration-File (18)."`
helps__31=`TN_ "The current status of the server is written to this file. If it starts with >>, then the file is created and status messages will be appended to it. Otherwise the file is removed before writing. For pattern replacements see Changer-Configuration-File (18)."`
helps__32=`TN_ "To prevent the server program from being started several times a lock file is created and this is it's name. For pattern replacements see Changer-Configuration-File (18)."`
helps__33=`TN_ "The name of a file, that a lock is set on, when a media changer is accessed. This is to prevent concurrent access, what might result in inconsistencies in the cartridge database. For pattern replacements see Changer-Configuration-File (18)."`
helps__34=`TN_ "Entries specifying files, that contain encryption keys for authenticating backup clients to the server. Each entry consists of a filename, optionally followed by a colon : and a specifier for client selection. If an entry lacks a client selector, this one will apply for all clients, that are not matched by any other entry. The client selector is either a list of comma-separated hostnames, a filename starting with a slash / containing hostnames one per line, or a command starting with a bar, that is stripped off before starting the command. The command gets the current client name as input on stdin, aside from arguments containing patterns (see below). If the command returns an exit status of 0, the client name will match the entry. Entries are separated by whitespace. If an entry must contain whitespace, it must be enclosed by double quotes. If colons are needed within the filenames, they must be escaped using a backslash. Each key file must contain at least 5 characters and must not have read permission for group or world. The pattern %H is replaced with the client name resolved from the IP-address. %h is similar to %H, but everything from and including the first dot is stripped off. For more pattern replacements see Changer-Configuration-File (18)."`
helps__35=`TN_ "If you are using the remote start option for backing up clients, this is the directory, where programs must reside, that can be started remotely. No other programs can be started remotely (for security reasons). For pattern replacements see Changer-Configuration-File (18)."`
helps__36=`TN_ "Here you may supply a (shell-) command to be run, when the backup server side wakes up, i.e. the server process starts. A %p appearing in this command is replaced with the name of the client, that connected the backup service. For more pattern replacements see Changer-Configuration-File (18)."`
helps__37=`TN_ "Here you may supply a (shell-) command to be run, when the backup server side goes to sleep, i.e. the server process ends. A %p appearing in this command is replaced with the name of the client, that connected the backup service. For more pattern replacements see Changer-Configuration-File (18)."`
