BASH Script Help Please :)

[azdaspaz]

Hey Guys,

Wondering if you can help me here.

Have a little script that will run as a cron job on my NAS that uploads a configuration file to a remote SFTP.

server.

The code has no trouble getting the file and uploading it. All i need for it to work as planned is automatically insert the password so that i can run it unattended.

I've added comments for clarification

Issue is on line 13 & 14 i believe.

 

Background about systems:
Local NAS = Freenas(FreeBSD)

Remote NAS = Synology DiskStation

#!/bin/sh#Store password in varPASS=myPassword#Local Path of file to uploadcd /mnt/DATA/confback#The File to uploadupload_file=$(ls | grep `date +%Y%m%d`.db)echo "${upload_file} Will now be uploaded"#initiate SFTP sftp -P 801 sftpAddress:/remote/path <<EOF# Auto enter password# Having issue with auto entering the passwordexpect "password"send "$PASS"# Upload the fileput $upload_file 

Cheers for the help.

Hi, I believe you just need a colon after password in line 13

 

expect "password:"

expect "password:"

 

Just gave that a go.

Still no result.

I also tried copying the entire line that would show up e.g "user @ domain 's password:" but did not succeed

Paste the output you are getting

[na_victo]

Also, make sure you add a newline \n after your password (I think haha...), haven't dont this in a while...

[azdaspaz]

I put the \n new line after the $PASS

expect "password:"send "$PASS\n"put $upload_file

Any it still asks for a password:

[root@[member='Adam']-nas] /mnt/DATA/scripts# sh ./script.sh20141127.db Will now be uploadeduser @ domain's password: 

If I type the password manually it continues through the script as follows:

[root@[member='Adam']-nas] /mnt/DATA/scripts# sh ./script.sh20141127.db Will now be uploadeduser @ DOMAIN password:Connected to remote.server.Changing to: /Adam FreeNAS/configssftp> expect "password:"Invalid command.sftp> send "myPassword\n"Invalid command.sftp> put 20141127.dbUploading 20141127.db to /Adam FreeNAS/configs/20141127.db20141127.db                                   100%  287KB 143.5KB/s   00:02sftp>sftp>[root@[member='Adam']-nas] /mnt/DATA/scripts#

Hope that's enough information. 

Bash scripting is still new to me, getting all the syntax correct is super fun. 

 

EDIT:

It seems that after it connects it tries to use the expect and send commands. 

They possibly might not be the correct commands for freebsd ? 

[na_victo]

Mmmmmmmmmmm, I think the problem may be related (corrections so far aside) to the script header

I'm not experienced with the expect package, but looking around I see that you may need to use this:

#!/usr/local/bin/expect

 

Try to create a short script just to connect to it: I found this short example:

#!/usr/bin/expect

spawn sftp username@hostname.com
expect "password:"
send "yourpasswordhere\n"
expect "sftp>"
send "cd logdirectory\n"
expect "sftp>"
send "put /var/log/file.log\n"
expect "sftp>"
send "exit\n"
interact

You could create a short script just to connect and try to invoke it from your bash script. First make sure you are able to connect with an Expect script, using that header.

 

I don't have a unix environment at home, so I can't try myself. I'll install a virtual machine and try later.

 

Hope it helps

Yeah from doing some more research I saw the expect env and gave that ago before...

Seems that FreeNAS(freeBSD) doesn't have that installed by default so I'll have to get that on there.

When ever you use those you just get:

./test.sh: spawn: not found./test.sh: expect: not found./test.sh: send: not found

The search continues  

[na_victo]

Oh, yes, make sure expect is installed on wherever you plan on running it . expect and send are not bash commands.

Yeah, looking for a port now for freeBSD... Will report back when I fix it

I put the \n new line after the $PASS

expect "password:"send "$PASS\n"put $upload_file

Any it still asks for a password:

[root@[member='Adam']-nas] /mnt/DATA/scripts# sh ./script.sh20141127.db Will now be uploadeduser @ domain's password: 

If I type the password manually it continues through the script as follows:

I know this is completely off topic. But i received a ltt "notification" saying that you mentioned me in a post. huh

was probably when I put in the host name for my server: root @ adam - nas.

I'd say that's it 

[TheGuyNL]

Shouldn't the connection string be in this format:

user:pass@hostname

EDIT:

 

To add a little bit more info, just do something like this:

#!/bin/sh#Store password in varUSER=myUserPASS=myPassword#Local Path of file to uploadcd /mnt/DATA/confback#The File to uploadupload_file=$(ls | grep `date +%Y%m%d`.db)echo "${upload_file} Will now be uploaded"#initiate SFTP sftp -P 801 $USER:$PASS@sftpAddress:/remote/path <<EOF# Upload the fileput $upload_file 

[azdaspaz]

#initiate SFTP sftp -P 801 $USER:$PASS@sftpAddress:/remote/path <<EOF

 

Gave that a go, Still is asking me for the password . 

The variables are passing fine it's just automatically filling in the password that's the issue  

[root @ adam-nas] /mnt/DATA/scripts# ./script.sh Will now be uploadedmyUser:myPassword @ domain's password:
