 =head1 NAME
 cssh - Cluster administration tool
 =head1 SYNOPSIS
 S<< cssh [options] [[user@]<server>[:port]|<tag>] [...] >>
 =head1 DESCRIPTION
 The command opens an administration console and an xterm to all specified 
 hosts.  Any text typed into the administration console is replicated to 
 all windows.  All windows may also be typed into directly.
 This tool is intended for (but not limited to) cluster administration where
 the same configuration or commands must be run on each node within the
 cluster.  Performing these commands all at once via this tool ensures all
 nodes are kept in sync.
 Connections are opened via ssh, so a correctly installed and configured
 ssh installation is required.  If, however, the program is called by "crsh"
 then the rsh protocol is used (and the communications channel is insecure),
 or by "ctel" then telnet is used, or by "ccon" then console is used.
 Extra caution should be taken when editing system files such as
 /etc/inet/hosts as lines may not necessarily be in the same order.  Assuming
 line 5 is the same across all servers and modifying that is dangerous.
 It's better to search for the specific line to be changed and double-check
 before changes are committed.
 =head2 Further Notes
 Please also see L</KNOWN BUGS>.
 =over
 =item *
 The dotted line on any sub-menu is a tear-off, i.e. click on it
 and the sub-menu is turned into its own window.
 =item *
 Unchecking a hostname on the Hosts sub-menu will unplug the host from the
 cluster control window, so any text typed into the console is not sent to
 that host.  Re-selecting it will plug it back in.
 =item *
 If your window manager menu bars are obscured by terminal windows see
 the C<screen_reserve_XXXXX> options in the F<$HOME/.clusterssh/config> file (see L</"FILES">).
 =item *
 If the terminals overlap too much see the C<terminal_reserve_XXXXX> 
 options in the F<$HOME/.clusterssh/config> file (see L</"FILES">).
 =item *
 When using cssh on a large number of systems to connect back to a single
 system (e.g. you issue a command to the cluster to scp a file from a given
 location) and when these connections require authentication (i.e. you are
 going to authenticate with a password), the sshd daemon at that location 
 may refuse connects after the number specified by MaxStartups in 
 sshd_config is exceeded.  (If this value is not set, it defaults to 10.)
 This is expected behavior; sshd uses this mechanism to prevent DoS attacks
 from unauthenticated sources.  Please tune sshd_config and reload the SSH
 daemon, or consider using the F<~/.ssh/authorized_keys> mechanism for 
 authentication if you encounter this problem.
 =item *
 If client windows fail to open, try running:
 C<< cssh -e {single host name} >>
 This will test the mechanisms used to open windows to hosts.  This could 
 be due to either the C<-xrm> terminal option which enables C<AllowSendEvents> 
 (some terminals do not require this option, other terminals have another 
 method for enabling it - see your terminal documentation) or the 
 C<ConnectTimeout> ssh option (see the configuration option C<-o> or file 
 C<$HOME/.clusterssh/config> below to resolve this).
 =back
 =head1 OPTIONS
 Some of these options may also be defined within the configuration file. 
 Default options are shown as appropriate.
 =over

 repeated multiple times.  Maximum level is 4.
 =item --evaluate '<[user@]<host>[:port]>', -e '<[user@]<host>[:port]>'
 Display and evaluate the terminal and connection arguments to display any
 potential errors.  The <hostname> is required to aid the evaluation.

 =back
 =head1 ARGUMENTS
 The following arguments are supported:
 =over
 =item [user@]<hostname>[:port] ...
 Open an xterm to the given hostname and connect to the administration
 console.  An optional port number can be used if sshd is not listening
 on the standard port (i.e., not listening on port 22) and ssh_config cannot
 be used.
 =item <tag> ...
 Open a series of xterms defined by <tag> in one of the supplementary
 configuration files (see L</"FILES">).
 B<Note:> specifying a username on a cluster tag will override any usernames
 defined in the cluster.
 =back
 =head1 KEY SHORTCUTS
 The following key shortcuts are available within the console window, and all
 of them may be changed via the configuration files.
 =over
 =item Control-q
 Quit the program and close all connections and windows.
 =item Control-+
 Open the 'Add Host(s) or Cluster(s)' dialogue box.  Multiple host or cluster 
 names can be entered, separated by spaces.
 =item Alt-n
 Paste in the hostname part of the specific connection string to each 
 client, minus any username or port, e.g.
 C<< scp /etc/hosts server:files/<Alt-n>.hosts >>
 would replace the <Alt-n> with the client's name in each window.
 =item Alt-r
 Retile all the client windows.
 =back
 =head1 EXAMPLES
 =over
 =item Open up a session to 3 servers
 S<$ cssh server1 server2 server3>
 =item Open up a session to a cluster of servers identified by the tag 'farm1' 
 and give the controlling window a specific title, where the cluster is defined 
 in one of the default configuration files
 S<$ cssh -T 'Web Farm Cluster 1' farm1>
 =item Connect to different servers using different login names.  NOTE: this can 
 also be achieved by setting up appropriate options in the F<.ssh/config> 
 file.  Do not close cssh when the last terminal exits.
 S<$ cssh -Q user1@server1 admin@server2>
 =item Open up a cluster defined in a non-default configuration file
 S<$ cssh -c $HOME/cssh.config db_cluster>
 =item Use telnet on port 2022 instead of ssh
 S<$ ctel -p 2022 server1 server2>
 =item Use rsh instead of ssh
 S<$ crsh server1 server2>
 =item Use console with master as the primary server instead of ssh
 S<$ ccon -M master server1 server2>
 =back
 =head1 FILES
 =over
 =item F</etc/clusters>, F<$HOME/.clusterssh/clusters>
 These files contain a list of tags to server names mappings.  When any name
 is used on the command line it is checked to see if it is a tag. 
 If it is a tag, then the tag is replaced with the list of servers.  The 
 format is as follows:
 S<< <tag> [user@]<server> [user@]<server> [...] >>
 e.g.
    # List of servers in live
    live admin1@server1 admin2@server2 server3 server4 
 All comments (marked by a #) and blank lines are ignored.  Tags may be 
 nested, but be aware of using recursive tags as they are not checked for.
 Extra cluster files may also be specified either as an option on the 
 command line (see C<cluster-file>) or in the user's F<$HOME/.clusterssh/config> 
 file (see C<extra_cluster_file> configuration option).
 B<NOTE:> the last tag read overwrites any pre-existing tag of that name.
 B<NOTE:> there is a special cluster tag called C<default> - any tags or hosts
 included within this tag will be automatically opened if no other tags
 are specified on the command line.
 =item F</etc/tags>, F<$HOME/.clusterssh/tags>
 Very similar to F<clusters> files but the definition is reversed.  The 
 format is:
 S<< <host> <tag> [...] >>
 This allows one host to be specified as a member of a number of tags.  This
 format can be clearer than using F<clusters> files.
 Extra tag files may be specified either as an option (see C<tag-file>) or within
 the user's F<$HOME/.clusterssh/config> file (see C<extra_tag_file> 
 configuration option).
 B<NOTE:> All tags are added together
 =item F</etc/csshrc> & F<$HOME/.clusterssh/config>
 This file contains configuration overrides - the defaults are as marked.
 Default options are overwritten first by the global file, and then by the
 user file.
 B<NOTE:> values for entries do not need to be quoted unless it is required 
 for passing arguments, e.g.
 C<< terminal_allow_send_events="-xrm '*.VT100.allowSendEvents:true'" >>
 should be written as 
 C<< terminal_allow_send_events=-xrm '*.VT100.allowSendEvents:true' >>
 =over
 =item auto_close = 5
 Close terminal window after this many seconds.  If set to 0 will instead wait 
 on input from the user in each window before closing. See also L<--autoclose> and L<--no-autoclose>
 =item auto_quit = yes
 Automatically quit after the last client window closes.  Set to anything
 other than "yes" to disable.  See also L<--autoquit> and L<--no-autoquit>
 =item clusters = <blank>
 Define a number of cluster tags in addition to (or to replace) tags defined
 in the F<clusters> file.  The format is:
 C<< clusters = <tag1> <tag2> <tag3> >>
 C<< <tag1> = host1 host2 host3 >>
 C<< <tag2> = user@host4 user@host5 host6 >>
 C<< <tag3> = <tag1> <tag2> >>
 As with the F<clusters> file, be sure not to create recursively nested tags.
 =item comms = ssh
 Sets the default communication method (initially taken from the name of the
 program, but can be overridden here).
 =item console_position = <null>
 Set the initial position of the console - if empty then let the window manager 
 decide.  Format is '+<x>+<y>', i.e. '+0+0' is top left hand corner of the screen,
 '+0-70' is bottom left hand side of screen (more or less).
 =item external_cluster_command = <null>
 Define the full path to an external command that can be used to resolve tags 
 to host names.  This command can be written in any language.  The script must 
 accept a list of tags to resolve and output a list of hosts on a single line.  
 Any tags that cannot be resolved should be returned unchanged.  
 A non-0 exit code will be counted as an error, a warning will be printed and 
 output ignored.
 =item extra_cluster_file = <null>
 Define an extra cluster file in the format of F</etc/clusters>.  Multiple
 files can be specified, separated by commas.  Both ~ and $HOME are acceptable
 as a reference to the user's home directory, e.g.
 C<< extra_cluster_file = ~/clusters, $HOME/clus >>
 =item key_addhost = Control-Shift-plus
 Default key sequence to open AddHost menu.  See L<KEY SHORTCUTS> for more information.
 =item key_clientname = Alt-n
 Default key sequence to send cssh client names to client.  See L<KEY SHORTCUTS> for more information.
 =item key_localname = Alt-l
 Default key sequence to send hostname of local server to client.  See L<KEY SHORTCUTS> for more information.
 =item key_paste = Control-v
 Default key sequence to paste text into the console window.  See L<KEY SHORTCUTS> for more information.
 =item key_quit = Control-q
 Default key sequence to quit the program (will terminate all open windows).  
 See L<KEY SHORTCUTS> for more information.
 =item key_retilehosts = Alt-r
 Default key sequence to retile host windows.  See L<KEY SHORTCUTS> for more information.
 =item key_username = Alt-u
 Default key sequence to send username to client.  See L<KEY SHORTCUTS> for more information.
 =item macro_servername = %s
 =item macro_hostname = %h
 =item macro_username = %u
 =item macro_newline = %n
 =item macro_version = %v
 Change the replacement macro used when either using a 'Send' menu item, or when 
 pasting text into the main console.  
 =item macros_enabled = yes
 Enable or disable macro replacement.  Note: this affects all the C<macro_*> variables above.
 =item max_addhost_menu_cluster_items = 6
 Maximum number of entries in the 'Add Host' menu cluster list before 
 scrollbars are used
 =item max_host_menu_items = 30
 Maximum number of hosts to put into the host menu before starting a new column
 =item menu_host_autotearoff = 0
 =item menu_send_autotearoff = 0
 When set to non-0 will automatically tear-off the host or send menu at 
 program start
 =item mouse_paste = Button-2 (middle mouse button)
 Default key sequence to paste text into the console window using the mouse.  
 See L<KEY SHORTCUTS> for more information.
 =item rsh = rsh
 =item ssh = ssh
 =item telnet = telnet
 Set the path to the specific binary to use for the communication method, else 
 uses the first match found in C<$PATH >
 =item rsh_args = <blank>
 =item ssh_args = "-x -o ConnectTimeout=10" 
 =item telnet_args = <blank>
 Sets any arguments to be used with the communication method (defaults to ssh
 arguments).  
 B<NOTE:> The given defaults are based on OpenSSH, not commercial ssh software.
 B<NOTE:> Any "generic" change to the method (e.g., specifying the ssh port to use)
 should be done in the medium's own config file (see C<ssh_config> and 
 F<$HOME/.ssh/config>).
 =item screen_reserve_top = 0
 =item screen_reserve_bottom = 60
 =item screen_reserve_left = 0
 =item screen_reserve_right = 0
 Number of pixels from the screen's side to reserve when calculating screen 
 geometry for tiling.  Setting this to something like 50 will help keep cssh 
 from positioning windows over your window manager's menu bar if it draws one 
 at that side of the screen.
 =item rsh = /path/to/rsh
 =item ssh = /path/to/ssh
 Depending on the value of comms, set the path of the communication binary.
 =item terminal = /path/to/xterm
 Path to the X-Windows terminal used for the client.
 =item terminal_args = <blank>
 Arguments to use when opening terminal windows.  Otherwise takes defaults
 from F<$HOME/.Xdefaults> or F<$HOME/.Xresources> file.
 =item terminal_font = 6x13
 Font to use in the terminal windows.  Use standard X font notation.
 =item terminal_reserve_top = 5
 =item terminal_reserve_bottom = 0
 =item terminal_reserve_left = 5
 =item terminal_reserve_right = 0
 Number of pixels from the terminal's side to reserve when calculating screen 
 geometry for tiling.  Setting these will help keep cssh from positioning 
 windows over your scroll and title bars or otherwise overlapping the windows
 too much.
 =item terminal_colorize = 1
 If set to 1 (the default), then "-bg" and "-fg" arguments will be added
 to the terminal invocation command-line.  The terminal will be colored
 in a pseudo-random way based on the host name; while the color of a terminal
 is not easily predicted, it will always be the same color for a given host
 name.  After a while, you will recognize hosts by their characteristic
 terminal color.
 =item terminal_bg_style = dark
 If set to C<dark>, the terminal background will be set to black and
 the foreground to the pseudo-random color.  If set to C<light>, then the
 foreground will be black and the background the pseudo-random color.  If
 terminal_colorize is C<zero>, then this option has no effect.
 =item terminal_size = 80x24
 Initial size of terminals to use. NOTE: the number of lines (24) will be 
 decreased when resizing terminals for tiling, not the number of characters (80).
 =item terminal_title_opt = -T
 Option used with C<terminal> to set the title of the window
 =item terminal_allow_send_events = -xrm '*.VT100.allowSendEvents:true'
 Option required by the terminal to allow XSendEvents to be received
 =item title = cssh
 Title of windows to use for both the console and terminals.
 =item unmap_on_redraw = no
 Tell Tk to use the UnmapWindow request before redrawing terminal windows.
 This defaults to "no" as it causes some problems with the FVWM window 
 manager.  If you are experiencing problems with redraws, you can set it to
 "yes" to allow the window to be unmapped before it is repositioned.
 =item use_all_a_records = no
 If a hostname resolves to multiple IP addresses, set to C<yes> to connect 
 to all of them, not just the first one found.
 =item use_hotkeys = yes
 Setting to anything other than C<yes> will disable all hotkeys.
 =item user = $LOGNAME
 Sets the default user for running commands on clients.
 =item window_tiling = yes
 Perform window tiling (set to C<no> to disable)
 =item window_tiling_direction = right
 Direction to tile windows, where "right" means starting top left and moving
 right and then down, and anything else means starting bottom right and moving 
 left and then up
 =back
 B<NOTE:> The key shortcut modifiers must be in the form C<Control>, C<Alt> or 
 C<Shift>, e.g. with the first letter capitalised and the rest lower case.  Keys
 may also be disabled individually by setting to the word C<null>.
 =item F<$HOME/.csshrc_send_menu>
 This (optional) file contains items to populate the send menu.  The
 default entry could be written as:
  <send_menu>
    <menu title="Use Macros">
        <toggle/>
        <accelerator>ALT-p</accelerator>
    </menu>
    <menu title="Remote Hostname">
        <command>%s</command>
        <accelerator>ALT-n</accelerator>
    </menu>
    <menu title="Local Hostname">
        <command>%s</command>
        <accelerator>ALT-l</accelerator>
    </menu>
    <menu title="Username">
        <command>%u</command>
        <accelerator>ALT-u</accelerator>
    </menu>
    <menu title="Test Text">
        <command>echo "ClusterSSH Version: %v%n</command>
    </menu>
  </send_menu>
 Submenus can also be specified as follows:
  <send_menu>
    <menu title="Default Entries">
      <detach>yes</detach>
      <menu title="Hostname">
          <command>%s</command>
          <accelerator>ALT-n</accelerator>
      </menu>
    </menu>
  </send_menu>

 =head1 KNOWN BUGS
 If you have any ideas about how to fix the below bugs, please get in touch
 and/or provide a patch.
 =over
 =item * 
 Swapping virtual desktops can cause a redraw of all the terminal windows.  This
 is due to a lack of distinction within Tk between switching desktops and 
 minimising/maximising windows.  Until Tk can tell the difference between the 
 two events, there is no fix (apart from rewriting everything directly in X).
 =back
 =head1 REPORTING BUGS

 =item *
 If you have issues running cssh, first try:
 C<< cssh -e [user@]<hostname>[:port] >>
 This performs two tests to confirm cssh is able to work properly with the
 settings provided within the F<$HOME/.clusterssh/config> file (or internal defaults).
 =over
 =item 1

 If you require support, please run the following commands
 and post it on the web site in the support/problems forum:

 Using the debug option (--debug) will turn on debugging output.  Repeat 
 the option to increase the amount of debug.  However, if possible please 
 only use this option with one host at a time, e.g. C<< cssh --debug <host> >> 
 due to the amount of output produced (in both main and child windows).
