To connect to a machine with ip MACHINE, you simply need to enter the below at command-line:
See below for a list of commands you would typically use once you
ftp to a machine.
Basic FTP Commands #
|Get help on FTP commands|
|Exit the FTP session|
|Set the mode of file transfer to binary|
|(Provides less chance of transmission error)|
|Unix operations on remote machine|
|Copy 1 file from local to remote|
|Copy multiple files from local to remote|
|Copy 1 file from remote to local|
|Copy multiple files from remote to local|
Automating FTP logins for specific IPs #
If you find yourself logging into a specific MACHINE too frequently, and if you want to save yourself from having to enter the username and password each time, you can save those credentials to your
~/.netrc file. See the example at the end of this post.
If that file does not exist, then create it, and remember to set its permission to 600.
touch ~/.netrc chmod 600 ~/.netrc
If the permissions are not set so, you will get this ftp error:
Error - .netrc file not correct mode. Remove password or correct mode.
Ignore the credentials in
But at times, you might need to manually log into a machine with a different set of credentials than the one saved in the
~/.netrc. To do so, run
ftp with the
-n option. And then use the
quote USER and
quote PASS commands to pass in the username and password.
> ftp -n <machine> ftp> quote USER <username> ftp> quote PASS <password>
Commenting out stuff in
.netrc does not seem to have a comment syntax. But this hack works ..
# character quickly followed by an FTP command foo (no space, ex:
#foo) is one way to “comment out” lines with valid .netrc keywords.
You cannot have such ‘comments’ after valid .netrc keywords are used.
So if you need to comment out a set of logins and passwords, do that before the first valid set of uncommented login credentials. See below for an example of that.
#machine foo.bar.com #login username1 #password pAsSw0rd1 machine foo.bar.com login username2 password pAsSw0rd2
