Проблема с подключением по SSH, почему подменяется пользователь?

Question

[trautw]

Привет.
На другом маке и в bash под виндой этот ключ с этой командой работают.
ssh зачем-то меняет пользователя ubuntu на slider. Пользователя slider в системе вообще нет.

oleg@mac:~/.keys$

Пользователь так же меняется при подключении к соседнему компу в домашней сетке

oleg@mac:~/.keys$ ssh admin@192.168.1.34
slider@192.168.1.34's password:

oleg@mac:~/.keys$ which ssh
/usr/bin/ssh
oleg@mac:~/.keys$ ls /usr/bin/ssh
-rwxr-xr-x  1 root  wheel  2099264 May  4 10:49 /usr/bin/ssh

[Arman]

в папке ~/.ssh если посмотреть файлы на наличие slider?

[trautw]

Arman, там пусто.
Подключиться получилось в итоге... но из под другого пользователя

su seconduser
...
bash-3.2$ ssh -i "oltr2.pem" [e-mail]
Welcome to Ubuntu 16.04.6 LTS (GNU/Linux 4.4.0-1088-aws x86_64)

ключ oltr2.pem тот же самый, скопировал из-за конфликта прав доступа (владелец другой)

[Arman]

trautw, вроде по разному делали: ubuntu ec2-18-215-187-173.compute-1.amazonaws.com первый вариант, второй вариант
[e-mail]

[trautw]

Arman, в первом варианте был -l ключ.
В общем, проблему нашел, в .bashrc было
alias ssh='ssh -l slider

Спасибо за помощь!
