When I ssh into my CentOS 7 machine and try to use sudo, I'm unable to submit my password.
Example prompt:
$ sudo ls
[sudo] password for edwardloveall:
Then I type my password, hit Enter, and nothing happens. No, command is run (seemingly), no "Sorry, try again.", no nothing. I am forced to Ctrl+C out of the prompt and do something else. This failure also happens when entering an ssh key password.
Return is accepted for other non-sudo commands and prompts. This behavior used to work, and as far as I know the system was not updated.
How can I fix or troubleshoot this?
Edit: Some more output to debug with:
$ id
uid=1000(edwardloveall) gid=1000(edwardloveall) groups=1000(edwardloveall),10(wheel)
$ ls -l /etc/sudoers
-r--r-----. 1 root root 4188 Mar 31 2016 /etc/sudoers
Also tried su -c date, attempted to enter a password (not sure if I had the right one) but the same thing happened: no response at the prompt.
More debug info:
$ hostname
portfolio
$ cat /etc/hosts
... snip comments ...
127.0.0.1 portfolio portfolio
127.0.0.1 localhost.localdomain localhost
127.0.0.1 localhost4.localdomain4 localhost4
# The following lines are desirable for IPv6 capable hosts
::1 portfolio portfolio
::1 localhost.localdomain localhost
::1 localhost6.localdomain6 localhost6
Edit:
I did find a workaround, if i hit Ctrl+D after entering my password it seems to let sudo work. I'd rather have Enter work however.
Fix (sortof)
I found a better work around.
If I edit my /etc/sudoers configuration (via visudo) and change
Defaults env_reset
to
Defaults env_reset,pwfeedback
Then * appear when I'm typing my password, and enter works! Changing it back has the same enter-not-allowed effect as before. If anyone knows why this works, I'd love to know.

Could you post output of commands:idandls -l /etc/sudoers. Can you executesu -c date(it requires yourrootpassword if exists, not theedwardlovealluser)?

Have you changed your hostname recently? Check and post output of:hostnameandcat /etc/hosts.
– Bob
Jul 29 at 12:54
Sure thing. I'm pretty sure that hasn't changed recently. Certainly not by me.
