Thanks for the initial replies, but this is a guru-to-linux_learner question. I need specifics.

I spent 5 hours spelunking the internet and reading man pages, before posting here.

I tried everything I could think of and I came close once, but crashed and burned.

You will note that these copying tools never have a place for password and usually no port reference.

My conclusion is that all these tools/utilities require some setup of SSH – otherwise I get “connection refused” or maybe nothing at all. There is also the option to run a daemon, something I would like to avoid.

I went into /etc/ssh/ssh_config and changed the port number that user-programs use - to 200 - for both machines. That does work, since the error message now has port 200 in it instead of 22.

ssh: connect to host 192.168.1.110 port 200: Connection refused

But ssh_config has a lot of other stuff in it (# indicates the default):

# Host *

# ForwardAgent no

# ForwardX11 no

# RhostsRSAAuthentication no

# RSAAuthentication yes

# PasswordAuthentication yes

# HostbasedAuthentication no

# BatchMode no

# CheckHostIP yes

# AddressFamily any

# ConnectTimeout 0

# StrictHostKeyChecking ask

# IdentityFile ~/.ssh/identity

# IdentityFile ~/.ssh/id_rsa

# IdentityFile ~/.ssh/id_dsa

Port 200

# Protocol 2,1

# Cipher 3des

# Ciphers aes128-cbc,3des-cbc,blowfish-cbc,cast128-cbc,arcfour,aes192-cbc,aes256-cbc

# EscapeChar ~

# Tunnel no

# TunnelDevice any:any

# PermitLocalCommand no

That’s why I need to hear from somebody who has actually done this (or a variation on it) and actually gotten it to work.

Thanks!

Can some guru help me out with a command line instruction that will copy a file from one box to another, in a standard ACID installation?

The boxes are behind a common router and have different port numbers for SSH (of course). If any config files changes are required, please show what is needed.

Secondly

If possible, is there a way to direct the output of this transfer to “stdin“ so that it can go directly into another program?

Thanks

Ken

Hi Ken,

Did you change your SSH port on the ACID systems from their default of 222 to 200? Port 222 is the default port set by ACID. Assuming you can get SSH working between the boxes, you can use SCP (secure copy) to copy between them. 73's, Keith

Yes, you use ssh for this (not scp). Here's how:

http://gnuru.org/article/1522/copying-with-scp-stdin

Yes OK - but I want it to go the stdin of the program running on the remote box. This is the box that is fetching the data/file. That means scp needs to send its file data to STDOUT (which would then be piped into the next program) Ken

No, you can't do that with scp, but you can do it with ssh, as described in the article. Like this: echo "some text" | ssh user@remote.host "cat > /remote/file" In this case, echo is writing to stdout. It is piped to ssh, which establishes a connection to remotehost. The other end of the pipe becomes stdout on remotehost, which connects to stdin of cat which dumps *its* stdout to a file. So, replace echo with your program on localhost which is producing data to stdout, and cat with your program on remotehost which is consuming data on stdin. Are you transferring a stream of data, or just a file? It's been I while since I had to do this, but I seem to remember it is a little counterintuitive. HTH, A

Andrew, apparently I still have not communicated this last part correctly.

Sorry. It was either not clear or I didn't understand.

My program - running on local host - is consuming data, not producing data. The data is an mp3 file on remote host. (We are going to turn that into a stream, but remote host doesn't know about that).

You have forced me to think about things differently however (outside the box, in fact). One alternate approach would be install my streaming program on remote host. Then the file it needs would be found locally.

Tnx Ken

How about an ssh tunnel? http://www.revsys.com/writings/quicktips/ssh-tunnel.html Does this stream really need to be encrypted? 73, Andrew

Hey Ken, KI6PSP did all the work for the ARRL news feed. http://ki6psp.blogspot.com/ David On Sun, Apr 10, 2011 at 10:32 AM, Ken <ke2n@cs.com> wrote:

73,

No it does not - but the local program needs to log into the remote system and, unless you do something special, that requires a password. I am learning that SSH provides a way to do that without flogging the password around in plain text. That's the bit where encryption is involved/needed. 73 Ken
