       clogin is an expect(1) script to automate the process of logging into a
       Cisco  router,  catalyst  switch, Extreme switch, Juniper ERX/E-series,
       Procket Networks, or Redback router.  There are  complementary  scripts
       for  Alteon, Avocent (Cyclades), Bay Networks (nortel), ADC-kentrox EZ-
       T3 mux, Foundry, HP Procurve switches and Cisco AGMs, Hitachi  routers,
       Juniper  Networks,  MRV  optical  switch,  Mikrotik  routers, Netscreen
       firewalls,  Netscaler,  Riverstone,  Netopia,  and  Lucent  TNT,  named
       alogin,  avologin,  blogin,  elogin,  flogin, fnlogin, hlogin, htlogin,
       jlogin, mrvlogin,  mtlogin,  nlogin,  nslogin,  rivlogin,  tlogin,  and
       tntlogin, respectively.

       clogin  reads  the  .cloginrc file for its configuration, then connects
       and logs into each of the routers specified on the command line in  the
       order  listed.   Command-line  options  exist  to  override some of the
       directives found in the .cloginrc configuration file.

       The command-line options are as follows:

       -S     Save the configuration on exit, if the device prompts at  logout
              time.  This only has affect when used with -s.

       -V     Prints package name and version strings.

       -c     Command  to  be  run  on  each  router list on the command-line.
              Multiple commands maybe listed by  separating  them  with  semi-
              colons  (;).   The  argument  should  be  quoted  to avoid shell

       -d     Enable expect debugging.

       -E     Specifies a variable to  pass  through  to  scripts  (-s).   For
              example, the command-line option -Efoo=bar will produce a global
              variable by the name Efoo with the initial value "bar".

       -e     Specify a password to be supplied when gaining enable privileges
              on  the  router(s).   Also  see  the  password  directive of the
              .cloginrc file.

       -f     Specifies an  alternate  configuration  file.   The  default  is

       -p     Specifies  a  password associated with the user specified by the
              -u option, user directive of the .cloginrc  file,  or  the  Unix
              username of the user.

       -v     Specifies  a  vty  password,  that  which  is  prompted for upon
              connection to the router.  This overrides the  vty  password  of
              the .cloginrc file's password directive.

       -w     Specifies  the  username  used  if  prompted when gaining enable
              privileges.  The  command-line  option  overrides  any  user  or
              enauser  directives  found  in  .cloginrc.   The  default is the
              current Unix username.

       -x     Similar to the -c option; -x specifies a file with  commands  to
              run  on  each  of  the  routers.   The  commands must not expect
              additional input, such as 'copy rcp startup-config'  does.   For

                 show version
                 show logging

       -y     Specifies  the  encryption  algorithm for use with the ssh(1) -c
              option.  The default encryption type  is  often  not  supported.
              See the ssh(1) man page for details.  The default is 3des.


       If  the  login script fails for any of the devices on the command-line,
       the exit value of the script will be non-zero and the value will be the
       number of failures.


       clogin recognizes the following environment variables.

              Overrides  the  user  directive found in the .cloginrc file, but
              may be overridden by the -u option.

       CLOGIN clogin will not change the banner on your xterm window  if  this
              includes the character 'x'.

              Specifies  an  alternative location for the .cloginrc file, like
              the -f option.

       HOME   Normally set by login(1) to the user's home directory,  HOME  is
              used by clogin to locate the .cloginrc configuration file.


       $HOME/.cloginrc   Configuration file.


       cloginrc(5), expect(1)


       clogin  expects  CatOS  devices  to have a prompt which includes a '>',
       Do not use greater than (>) or pound sign  (#)  in  device  banners  or
       hostnames  or  prompts.  These are the normal terminating characters of
       device prompts and the login scripts need to locate the initial prompt.
       Afterward,  the full prompt is collected and makes a more precise match
       so that the scripts know when the device is ready for the next command.

       All these login scripts for separate devices should be rolled into one.
       This goal is exceedingly difficult.

       The HP Procurve switch, Motorola BSR, and Cisco AGM CLIs  rely  heavily
       upon terminal escape codes for cursor/screen manipulation and assumes a
       vt100 terminal type.  They do not provide a  way  to  set  a  different
       terminal type or adjust this behavior.  The resulting escape codes make
       automating interaction with these devices very difficult or impossible.
       Thus bin/hpuifilter, which must be found in the user's PATH, is used by
       hlogin to filter these escape sequences.  While this works for rancid's
       collection,  there  are side effects for interactive logins via hlogin;
       most of which are formatting annoyances that may be remedied by  typing
       CTRL-R to reprint the current line.

       WARNING: repeated ssh login failures to HP Procurves cause the switch's
       management  interface  to  lock-up  (this  includes  snmp,  ping)   and
       sometimes it will crash.  This is with the latest firmware; 5.33 at the
       time of this writing.
