It all depends on what you're running for an operating system.

I would suggest you get expect.

always a mess to log on

http://www.vandyke.com - get their SecureCRT product (if you are a CLI
admin, how can you survive without it)

It sends breaks, has built-in scripting, has ssh support, and lots of
goodies.

Use a scripting language like 'expect'.
Expect scripts work like thier name says:

expect 'this'
send 'that'

The expect home page is at:
http://expect.nist.gov/

And I believe there is a version for NT, should run fine on 2000.

Any telnet client worth it's salt will have scripting ability. I *HATE*
MS telnet as much as I *LOVE* vi as my editor. So I would suggest you
look at Tera Term (free telnet client w/ add on support for SSH) or ZOC
(www.emtec.com) shareware.

Van Dyke Technologies (www.vandyke.com) puts out a neat telnet program
called CRT. Extremely easy script setup. I do a lot of mass configuring
with mine.

set wshbin = createobject("wscript.shell")
output = wshbin.run("telnet 10.1.1.2")
wscript.sleep(400)
wshbin.Sendkeys "password~"
wscript.sleep(100)
wshbin.Sendkeys "enable~"
wscript.sleep(100)
wshbin.Sendkeys "enablepassword~"
set wshbin = nothing
wscript.sleep(100)
wscript.quit

Use notepad and save the above as xxx.vbs. ~ is a return, not part
of my passwords, so use it.

Install windows script host, I think that is available in "add
programs/windows setup".

I also did this:
Install Microsoft Scripting Engines Version 5.5
Here:
http://msdn.microsoft.com/scripting/default.htm?/scripting/windowshost
/download/default.htm

There is something wrong with win98. I get an error after using this
90% of the time, and no one knows why. So I run the script, error
returns, and enter closes error dialog, but I am immediately in the
telnet and can start typing.

If you have win2000 maybe this will run right. I use it to
extensively enter commands.

I have several scripts using another script host tst10.exe. To be
error free, where they just execute no problem, I can't use the built
in vbs. Here is what I do with this:

1 clear interf bri0
2 clear arp
3 disconnect interf bri0
4 clear ip nat tran
5 no debug all
6 reload (strange, i don't think I have the router set to reload from
a telnet, so maybe I never tested this one. Normally you have to
reload from com port control)

One click gets these standard things done, cool.

: hi,

[Unknown]

Although I wouldn't recommend having anything that logs in
automatically to routers, you can create a file of commands and cut
and paste it into your Telnet session (if your telnet client allows
it). The commands will be executed one at a time. I used this method
when updating a setting on 20 switches. All I did was initiate the
Telnet connection and then cut and pasted in series of commands whyich
included the login password, the ENABLE command, the Enable password,
the config t command and then all the configuration commands ending
with END and COPY RUN START.

Worked like a charm and cut down my update time significantly.

But I wouldn't take leaving a text file with passwords in it lying
around lightly. Seriously think about it before you do it. I
generate this text prior to a job like described above and never keep
the text permanently.
