.SH DESCRIPTION
.B clogin
is an
.BR expect (1)
script to automate the process of logging into a Cisco router,
catalyst switch, Extreme switch, or Redback router. There are
complementary scripts for
Alteon,
Bay Networks (nortel),
ADC-kentrox EZ-T3 mux,
Foundry,
HP Procurve Switches,
and Juniper,
named
.B alogin,
.B blogin,
.B elogin,
.B flogin,
.B hlogin,
and
.B jlogin,
respectively.
.PP
.B clogin
reads the
.IR .cloginrc
file for its configuration, then connects and logins into each of the
routers specified on the command line in the order listed. Some command-line
options exist to override directives found in the
.IR .cloginrc
configuration file.
.PP
The command-line options are as follows:
.PP
.TP
.B \-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 expansion.
.\"
.TP
.B \-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 "foo".
.\"
.TP
.B \-e
Specify a password to be supplied when gaining enable privileges on the
router(s). Also see the password directive of the
.IR .cloginrc
file.
.\"
.TP
.B \-f
Specifies an alternate configuration file. The default is
.IR "$HOME/.cloginrc" .
.\"
.TP
.B \-p
Specifies a password associated with the user specified by the
.B \-u
option, user directive of the
.IR .cloginrc
file, or the Unix username of the user.
.\"
.TP
.B \-s
The filename of an
.BR expect (1)
script which will be sourced after the login is successful and is expected
to return control to
.B clogin,
with the connection to the router intact, when it is done. Example script(s)
can be found in util/*.exp.
.\"
.TP
.B \-t
Alters the timeout interval; the period that
.B clogin
waits for an individual command to return a prompt or the login process to
produce a prompt or failure. The argument is in seconds.
.\"
.TP
.B \-u
Specifies the username used when prompted. The command-line option overrides
any user directive found in
.IR .cloginrc .
The default is the current Unix username.
.\"
.TP
.B \-v
Specifies a vty password, that which is prompted for upon connection
to the router. This overrides the vty password of the
.IR .cloginrc
file's password directive.
.\"
.TP
.B \-w
Specifies the username used if prompted when gaining enable privileges. The
command-line option overrides any user or enauser directives found in
.IR .cloginrc .
The default is the current Unix username.
.\"
.TP
.B \-x
Similar to the
.B \-c
option;
.B \-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 example:
.PP
.in +1i
.nf
show version
show logging
.fi
.in -1i
.\"
.TP
.B \-y
Specifies the encryption algorithm for use with the
.BR ssh (1)
\-c option. The default encryption type is often not supported. See the
.BR ssh (1)
man page for details. The default is 3des.
.El
.SH ENVIRONMENT
.B clogin
recognizes the following environment variables.
.PP
.TP
.B CISCO_USER
Overrides the user directive found in the
.IR .cloginrc
file, but may be overridden by the
.B \-u
option.
.\"
.TP
.B CLOGIN
.B clogin
will not change the banner on your xterm window if this includes the
character 'x'.
.\"
.TP
.B HOME
Normally set by
.BR login (1)
to the user's home directory,
HOME is used by
.B clogin
to locate the
.IR .cloginrc
configuration file.
.El
.SH FILES
.ta \w'xHOME/xcloginrc 'u
\fI$HOME/.cloginrc\fR Configuration file.
.SH "SEE ALSO"
.BR cloginrc (5),
.BR expect (1)
.SH CAVEATS
The HP Procurve switches that are Foundry OEMs use flogin, not hlogin.
.SH BUGS
All these login scripts for separate devices should be rolled into one.
.PP
The HP Procurve switch CLI relies heavily upon curses based 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. Therefore, bin/hpfilter is used by hlogin to filter these.
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 hitting CTRL-R to reprint the current line.
