Connecting to sftp using lftp get operation not permitted

[hasandjamil]

I can't list the home directory at remote server by using lftp. The error is below.

[user@clientserver ~]$ lftp

lftp :~> lftp -u user,password sftp://remoteserver

lftp user@remoteserver:~> ls

ls: Fatal error: pseudo-tty allocation failed: Operation not permitted


It is not only ls, but also the other commands as well.

While I'm using sftp user@remoteaddress, it's working properly and all the command like ls, cd, pwd, put, etc. is working.

What is the output from uname -a ?

However, if I used sudo before lftp, it works! I think lftp doesn't need privileges, but somehow in my case, lftp asked privilege.
