Line Breaks / Carridge Returns in Config?

aidanhammond

Hello,

I have a 2511 access router and would like to set it up using an example config I found on these forums (posted by wildfire, thank you very much)... My only problem is the config posted has carridge returns in it, and when I send the file to the terminal via hyperterminal / teraterm it just doesn't compute with the router and throws up a load of errors.

Anyone know how to go about sending the config to the router with carrige returns / line breaks in things like the message of the day -- The config I'm using can be found here:

TIA,

Aidan.

I'm not sure if this is what you are running into, but I know it stumped me when uploading some configs to a PIX. If I used a config made in Vi or Wordpad it worked fine, but if I used notepad it did not. Like you mentioned, it has to do with the "return" key interpretation.

I forget which editor used what, but basically one used an EOL followed by CR (end of line/carriage return) while the other only used the EOL.

That'd make sense, anyone else able to shed a little more light?

Thanks for the reply.

After a lot of googling... I still can't find an answer to this one - anyone got any suggestions?

Did you copy/paste from wildfire's post directly to hyperterminal? Did you send as a text file? What method did you use, exactly? Thanks.

I didn't think wordpad/notepad would make a difference because Windows uses UTF encoding by default. You should use a text editor that can encode in ASCII (I've been using EditPad with no problems)

I've tried taking wildfire's post and sending to console by right clicking in hyperterminal / send to console... and also by sending a text file by copying from the post and pasting into notepad, then sending to the console... neither method works

Hope this answers your question,

aidanhammond,

Each line in either startup_config or running_config is the result of either default, manual configuration of each item, or a configuration download to the networking device. As you're learning, cut & paste configuration doesn't work.

Before you venture forth into "instantly configuring" a terminal server, I think you need to learn what the following modes are:

1. User EXEC Mode
2. Priviledged EXEC Mode

Post back when you've learned what those modes are.

... As this is a forum to share knowledge, and this question has stumped a few other users, maybe you'd be so kind to share the answer to the question and so assisting not just me, but other members of the forum.

I agree with tech-airman -- it sounds like you didn't go into config mode.

If that's not the case, copy and past your output from hyperterm showing the errors.

aidanhammond

I can assure you I was in config mode... it applys the config right up to the first line break in which case it cancels back to #, by that I mean IP addresses, interface names, hostname etc etc etc are all set... It follows the config until the first line break.

I'm afraid I'm not with the kit at the moment, once I am I'll record the session and post the result.

Have you tried copying and pasting the whole config into notepad and then modify the config so that it is only commands. Delete all the exclamation points and everything that is not a command. Then copy and paste little pieces of the config at a time. IF you try pasting 2 or 3 pages of config into the CLI, it's gonna screw it up.

We had a technician come in one day when we went live on frame-relay that was trying to do that. He was trying to copy and paste 2 and 3 pages at a time of all kinds of VOIP and DID numbers, and he was wondering why the config wasn't loading correctly.

When I copy and paste (which I try to never do because of problems like this) I always use notepad. Like Netstudent said to it piece by piece that way if there is a problem it won't mess up the whole config.

Also I hope you are not trying to put the whole thin in there, some of that is not a config!

aidanhammond

I am doing it bit by bit... for instance, the banner motd won't go in when there is a line break... how do you guys over come this - how do you put a line break in when trying to write a multi-line message?

Aidan.

networker050184

Did you put it in notepad?

wait2dominate

I think what he is running into is that the banner is to long for one line....

I.E.

banner motd % Authorized personel only. This is a secure system that you are not allowed to access without proper authorization from a network administrator. If you do not have this access, exit the system or you will be prosecuted %

Such that the word not is on an additional line in the config that has been posted from a sh run command.

In any situation, I would end up placing the config in notepad nad editing it into one line without a carrage return, as this should clear up the issue.

aidanhammond

What I'd like to do is put carridge returns in my config... so i can set the banner motd to say:

Hello this is my router
my very special router
this is on many lines.

rather than:

Hello this is my router my very special router this is on many lines.

Hope this clarifys what I am trying to do...

Aidan.

Netstudent

or you could always just do the banner manually.

aidanhammond

Netstudent... What a wonderful suggestion, but how do you do line breaks / carridge returns?

Either way, pasting or typing from scratch it'll still bring me back to my original question...

All right, maybe a long shot as I have not tested this, but I found here:

Changing the End-of-Line Character
The end of each line typed at the terminal is ended with a CR+LF (Carriage Return plus Line Feed) signal. The CR+LF signal is sent when a user presses Enter or Return. To cause the current terminal line to send a CR signal as a CR followed by a NULL instead of a CR followed by a line feed (LF), use the following command in EXEC mode:

Router> terminal telnet transparent

Causes the current terminal line to send a CR signal as a CR followed by a NULL instead of a CR followed by an LF.

This command ensures interoperability with different interpretations of end-of-line handling in the
Telnet protocol specification.
