I am having an issue with lftp where it gets stuck on `ls' at 0 [Connecting...] for an SFTP connection.
Versions:
- Linux 3.10.0-1160.108.1.el7.x86_64 #1 SMP Thu Jan 4 14:55:32 EST 2024 x86_64 x86_64 x86_64 GNU/Linux
- LFTP | Version 4.4.8
Here how I am running it:
user@server:~$ lftp -d
lftp :~> open -u Uname,Passwd -p 22 sftp://test.host.com
lftp Uname@test.host.com:~> ls
---- Running connect program (ssh -a -x -s -l Uname -p 22 test.host.com sftp)
---> sending a packet, length=5, type=1(INIT), id=0
<--- Password authentication
`ls' at 0 [Connecting...]
I tried using the various lftp "set" commands with no luck.
I then tried connecting using the "sftp" client on Linux and it works.
user@server:~$ sftp -oPort=22 Uname@test.host.com
Password authentication
Uname's password
Connected to test.host.com.
sftp> ls
In Out Received
sftp>
I had already done the host key fingerprint verification and it exists in the /home/user/.ssh/known_hosts file.
Not sure why it is not working when using lftp. Any ideas?
Thanks
Edit 1:
user@server:~$ lftp sftp://test.host.com
lftp test.host.com:~>
Edit 2 (using ssh):
user@server:~$ ssh Uname@test.host.com
Password authentication
Uname's password
PTY allocation request failed on channel 0
Sorry, SFTP Only - pty-req not allowed.
Connection to test.host.com closed.
Edit 3 (using sftp -vvv):
user@server:~$ sftp -vvv -oPort=22 uname@test.host.com
