send scp command with path .

[rleon]

How do I send an scp command?

I cant seem to be able to figure out how to do the characters after the host.

scp -p -r myfile root@host:/path/to/dir/

   crt.Screen.Send("ssh -oStrictHostKeyChecking=no root@" + host + '\r')

thanks

Hi rleon,

Sorry to appear dense, but I don't understand what you don't understand.

Also, your question is about scp, but then the example code is ssh?

I assume "/path/to/dir/" is a literal string, you would just treat it as such:

crt.Screen.Send("ssh -oStrictHostKeyChecking=no root@" + host + ":/DirA/DirB/DirC/etc" + '\r')

or

crt.Screen.Send("scp -p -r my file root@" + host + ":/DirA/DirB/DirC/etc" + '\r')

Hi Brenda

lol sorry I wasnt clear

crt.Screen.Send("scp -p -r -oStrictHostKeyChecking=no ssh_client.tar root@" + host + ":/root" + '\r')

I tried what you suggested but I get an error now.

For some reason its putting an extra character in there.

# scp -p -r -oStrictHostKeyChecking=no ssh_client.tar root@myhost
[rleon:/home/rleon]# :/root
-bash: :/root: No such file or directory

Hi rleon,

I would say then that the info read from the hosts file includes an extra end of line character that needs stripped!

hmmm I checked that ..

No extra characters.

The extra char(s) are there, you just won't be able to see them since they're non-printing.

This should demonstrate for you what's going on:

with open('/Users/rleon/Documents/hosts.5') as hosts_:
    for host in hosts_:
        crt.Dialog.MessageBox(host.replace("\r", "[CR]").replace("\n", "[LF]"))

The for-loop in python doesn't strip all end-of-line chars for you, so you have to be aware to remove them from variables so that you can use them in a command line. If the host variable has an LF or a CR in it, it will surely affect the way any command that you craft using the host variable.

It has an LF in the dialog box.

But I dont see any lines or characters returns.

# cat -vet hosts 
10.255.43.12$
10.255.43.13$
10.255.43.14$
10.255.43.15$

They're in there, rleon, otherwise there wouldn't be any lines in your file!
(your file would show up as a singular, long line)

Lines in a text file are terminated with special characters to signal where the end of the line is (EOL = End Of Line).

On UNIX-based systems, the EOL character is typically a \n (LF) character, which 'cat' displays as '$' (as described in the man page for 'cat').

Your output of 'cat -vet hosts' clearly shows '$' at the end of each line.

I've already shown you one way to use 'replace()' to make the \n char visible in the dialog as [LF]. All you need to do is use that same replace() call to replace any LF or CR with an empty string (e.g. remove them), as in:

host = host.replace("\n", "").replace("\r", "")
