[vtysh] Never skip authentication, and add support for multiple -c commands
2006-07-27 Andrew J. Schorr <ajschorr@alumni.princeton.edu> * vtysh.1: Document new options -d and -E, and note that now multiple -c options may be supplied, with embedded linefeed now supported. In BUGS section, remove warning about vtysh causing a daemon to freeze, since this has been fixed. * vtysh_main.c: (usage) Add new -d and -E options. And note that -c can be used multiple times, possibly with embedded linefeeds. (longopts) Add new -d and -E options. (main) Add new -d and -E options, and create a linked list to support multiple -c options. Do not call vtysh_connect_all until after vtysh_read_config(config_default) and vtysh_auth have succeeded. This prevents the vtysh.conf file from configuring any daemons, and it ensures that authentication has been passed before we send any commands to any daemons. Call vtysh_connect_all with any daemon name supplied with -d. If it is unable to connect to any daemons, issue an error message and exit immediately. When used in -c mode, call vtysh_execute("enable") before executing the commands in order to match interactive behavior. And detect embedded linefeed chars in -c commands and break them up appropriately. * vtysh.h: (vtysh_connect_all) Fix proto to reflect new daemon_name argument, and that it now returns an integer -- the number of daemons to which we were able to connect. * vtysh.c: (vtysh_connect_all) Add a new daemon_name argument. If supplied, connect only to that daemon. And return the number of daemons to which we were able to connect. (vtysh_prompt): Performance enhancement -- make struct utsname static so we call uname to get the hostname only once.
