lftp file configuration and stored password - lftp

I am connecting to some ftp server with lftp.
lftp -u login,password -e "ls /someFolderOnTheServer" bla.node.org"
Does someone know how I can setup things such that the login and the
password are read from some configuration file instead ?
many thanks for your valuable help.

Yes, it's possible. Use ~/.netrc file.

How to use PGPASS file in Powershell to avoid password prompt?

I had to automate my postgre database backup. As instructed by my software vendor I am trying to use pg_dump.exe (see below) file to take a backup but that prompts me for password.
.\pg_dump.exe -h localhost -p 4432 -U postgres -v -b -F t -f "C:\Backup\Backup.tar" Repo
So googled and found that as per "https://www.postgresql.org/docs/9.6/libpq-pgpass.html" I can create a pgpass.conf file within 'C:\Users\User1\AppData\Roaming\postgresql\pgpass.conf" which I did.
Then I tried to pass data of pgpass.conf file to env variable before executing my pg_dump command. But it is not working. Still I am getting prompt to enter password. This is the content of pgpass.conf file: *:*:*:postgres:password
Below is the code I am trying in PowerShell,
$Env:PGPASSFILE="C:\Users\User1\AppData\Roaming\postgresql\pgpass.conf"
cd "C:\Program Files\Qlik\Sense\Repository\PostgreSQL\9.6\bin"
.\pg_dump.exe -h localhost -p 4432 -U postgres -v -b -F t -f "C:\Backup\Backup.tar" Repo
Why am I still being asked for password?
When I type following code $Env:AppData I get following response "C:\Users\User1\AppData\Roaming"
Everywhere there are guidance on how to use it in UNIX or command prompt but not in powershell. Any help is appreciated. Also if you could direct me how to secure this password file then it will be great.
With password prompt I cannot automate it with windows task scheduler.
I suspect you have a suitable solution, however, as a quick (and not secure) workaround via the command prompt, you can use the variable PGPASSWORD to hold the password then run the backup script.
A sample might be something like:
SET PGPASSWORD=password
cd "C:\Program Files\Qlik\Sense\Repository\PostgreSQL\9.6\bin" pg_dump.exe -h localhost -p 4432 -U postgres -b -F t -f "d:\qs_backup\QSR_backup.tar" QSR

I have yet to get the damned thing to work yet, but I did find this:
-w
--no-password Never issue a password prompt. If the server requires password authentication and a password is not available by other means
such as a .pgpass file, the connection attempt will fail. This option
can be useful in batch jobs and scripts where no user is present to
enter a password.
I don't see a -w parameter in your call to pg_dump
I used pg_hba file to allow connection "trust" this is riskier method but I had to get things done ASAP. Thank you for your time and effort

Upload file from local to sftp based remote server using shell/bash script

I'm looking for a shell/bash script that can be used to transfer a file from my local to a remote serve using sftp protocol.
I have the one for ftp but can't figure out for sftp.
Any help here would be greatly appreciated.
You could use lftp:
lftp -u USER,PASS -e "put LOCAL_FILE;quit" sftp://SERVER_ADDRESS

pass password to sftp in a bash script

I would like to automate a bash script, that connects to server using sftp and does a file transfer. I have the password for this, and initially I tried for this
sftp $acc#$host << EOF
<passwd_here>
cd $dir
get $file
quit
EOF
but it still prompted for password, and I had to enter it manually at the prompt.
After searching SO, I found this post which had a solution with expect, which I tried and I got the following error:
Script:
sftp -b cmdfile.txt $acc#$host
expect "Password:"
send "<passwd>\n";
interact
Error:
Permission denied (publickey,keyboard-interactive).
cmdfile.txt
cd $dir
get $file
quit
Please let me know, How to connect using the password in a bash script?
Please try the below steps
lftp -u $user,$pass sftp://$host << --EOF--
cd $directory
put $srcfile
quit
--EOF--
With scp/sftp you should use key-based authentication. Public key from the user you want to authenticate copy into ~/.ssh/authorized_keys file on the server, into home directory of user on which you want log on. Storing password in clear text on client side is not a good practice, you know :) That way you "workaround" problem of reading password from the prompt too.
Yes key-based auth is the way to go.

Batch script connect to ftp sever?

I am trying to connect to my ftp server by running a batch script. I can log into it fine by typing the following:
ftp home.ptd.net
USERNAME
PASSWORD
cd Public
put FILENAME.txt
bye
But if I put this into a script in this order, it connects to the server, but still asks for a username. Can anyone point me in the right direction on how to make it login? Thanks.
please see the following msdn article:
ftp reference from msdn
i think you need to place the commands in a text file and pass it to the ftp command with the -s parameter

How do you connect to FTP server via a shell-script

I am writing my first shell-script ever and I am trying to connect to an FTP server. However, I am utterly at a loss for how to do this. I tried a google search, but I am still stumped.
I am trying to connect with a username and password (not a ssh id).
Thanks for your help. Again this is my first shell-script ever.
The command man ftp should give you the necessary pointers.
This being said, this page might help you build a complete shell script
Here how you connect to FTP server via a shell-script :
nano MyConnectFTPScript.sh
#!/bin/sh
$HOST='hostAdresss'
$USER='NameOfUser'
$PASSWD='YourPass'
$FILEtoPut='myFile1'
$FILEtoGet='myFile2'
$FILEtoDelete='myFile3'
ftp -n $HOST <<END_SCRIPT
quote USER $USER
quote PASS $PASSWD
put $FILEtoPut
get $FILEtoGet
delete $FILEtoDelete
quit
END_SCRIPT
exit 0
chmod +x MyConnectFTPScript.sh
and execute :
./MyConnectFTPScript.sh
I hope these will be helpful.
