Are you sending the CR after your FTP commands? I don't see them in

kevin... looks like i about go this going...

here is my script...

#!/usr/local/bin/expect -f
set timeout 20
spawn sftp -vvv -oport=22 LSAMSSO@10.110.4.99 expect {
default {exit 2}
"continue connecting (yes/no)?" {send "yes\n"; exp_continue}

"password:"

[send "*********\n"; exp_continue} "sftp>"
}
send "lcd /lsams/sftp/export"
expect "sftp>"
send "cd /put/lsams/sftp/export"
expect "sftp>"
send "PUT srvbill.ZIP"
expect "sftp>"
send "lcd /tmp"
expect "sftp>"
send "cd /put/lsams/sftp/export"
expect "sftp>"
send "GET srvbill.ZIP"
expect "sftp>"
expect {
default {exit 2}
"not found" {exit 3}
"sftp>"
}
send "quit\n"
exit 0


so looks like i'm getting through the password authentication
however

my

sftp command do not seem to be working.

last few lines in log show...

debug3: Sent message fd 5 T:16 I:1
debug3: SSH_FXP_REALPATH . -> /home/lsamsso
sftp> lcd /lsams/sftp/exportcd /put/lsams/sftp/exportPUT

srvbill.ZIPlcd

/tmpcd /put/lsams/sftp/exportGET srvbill.ZIP


obviously i'm not doing something right with the "send" and

"expect

"sftp>"

commands... but can you see what the issue is?

All of the sftp commands will need to be in expect script. Spawn
starts the sftp connection inside of the expect script. Expect
waits for certain text, and then when it sees it, sends the
response. The script below is very basic, but there plenty of
examples of complex scripts out there. Ours starts the sftp
session and waits for the other side to send "password:" When

it

sees that, it sends our password (I see I striped out a " when I
was sanitizing that

script).

It then waits for it come back to command prompt "sftp>" When it

sends

that, it sent our put command and a carriage return. "mput *\n"

It

waits for the command prompt again, and then sends quit to

disconnect.

kevin...

we have key auth working for sftp but want to allow user
password

also...

so obviously why i'm pursuing expect...

using EXPECT, can I simply spawn the same sftp command I use

for

key

auth...??

l_sftpCommand = 'PATH=$PATH:/QOpenSys/usr/bin && sftp '

+

'-vvv '

+

'-oport=' + %trim(l_port) + ' '

+

'-b /tmp/sftpBatchFile.BCH '

+

%trim(l_userName) + '@' + %trim(l_host);

so basically in my EXPECT script, i say "spawn" and then

specify

the

same sftp

command above and it will utilize the batch file? or do my

sftp

get/put

commands need to be built into the EXPECT script?

also, by using EXPECT (instead of SFTP), is there a way

to

specify

the

port to

use?

It looks to me like if you follow those instructions

it

be

need

to

either

copy/move it, or create a symbolic link (the better

option)

Hopefully someone can help...

I'm following the short instructions in this link...

https://www.scottklement.com/expect/

however, when I am done and check for the expect
command

using

the

following command, I do not see it...

WRKLNK OBJ('/qopensys/usr/bin/expect')

It appears i am not doing the install correctly.

What

am

I

missing?
