I'm new to PostgreSQL. I just installed the Postgres.app on my Mac and wanted to use the psql command in the terminal. However, when I type psql in the terminal, I'm asked to input the password. I was never asked to set a password during installation so I'm confused what the password is. I've looked at other similar questions but none of them worked for my case.
$ psql
$ Password for user kaili:
$ psql: error: connection to server on socket "/tmp/.s.PGSQL.5432" failed:
FATAL: password authentication failed for user "kaili"
Could anyone give me some hints on how to access the database as the user kaili? Thank you!

hi am following the following tutorial
https://www.youtube.com/watch?v=qw--VYLpxG4&t=2224s
and when i add psql into my path and then type it into the terminal it asks for my administrator datails of which i give then it shows this
psql: error: FATAL: password authentication failed for user "aarushsharma"
how do i find out the password for aarushsharma?
try to change METHOD in pg_hba.conf file from md5 to trust, restart postgresql server and change your user password
ALTER USER aarushsharma WITH PASSWORD 'your_password';
and set METHOD to md5 again
hello I'm trying out Tectia 6.4 via cmd but I'm having trouble login in with password as argument. I always get the error "too many argument"
I tried
sftpg3.exe host password
sftpg3.exe host --password=password
sftpg3.exe host -p password
If i just enter host-name i get the prompt for the password in order to login. there no way to use password as argument in order to log in via cmd? I look into help and they have option for password but it does not seems to be working for me
Thanks
sftp3.exe --password=yourpassword username#host
Make sure your options are first and you are including your username#host in the command also.
optional -B file.txt where file.txt includes your FTP command to execute after connecting.
NOTE: Having your password in cleartext is considered a security risk.
From workstation (Windows) trying to execute
knife ssh 'name:*' 'sudo chef-client'
But it shows error message of
WARNING: Failed to connect to ******** – Net::SSH::AuthenticationFailed: Authentication failed for user ************
How do I solve this error?
Another question is how to execute 'sudo chef-client' on all nodes from workstation without using any passwords?
If you run knife ssh --help you'll get a list of available options. Try adding -VV for verbose output. That's usually helpful as it should tell you what user knife is trying to connect as.
My guess is you'll have to incorporate one or more of the ssh options (a few listed here):
-x, --ssh-user USERNAME
-i, --identity-file IDENTITY_FILE
-P, --ssh-password [PASSWORD] (will prompt if flag specified but no password is given)
The docs (https://docs.getchef.com/knife_ssh.html) also have some helpful examples
Your SSH authentication isn't working, fix that. Key-based authentication is something I'm sure you can look up on Google, but in general set your public key in .ssh/authorized_keys and setup your agent on your workstation.
I just installed postgresql 9.0 on my pc.
When it ask for password during install, I entered password.
after install I went to command prompt to import a SQL file.
I use the command psql -f filename.sql. This prompts me for a password to which I enter password.
It then complains that authentication failed for user Morne Nel. I dont exist as a user yet.
I then tried psql -h localhost -U postgres to which I enter the password password.
Only to get this message:
FATAL: Password authentication failed for user "postgres"
What Can I do to resolve this madness?
# Could it be that Jasper Reports server might have something to do with it, is also installs prostgres does iet not?
So is seems that Jasper Reports Server was the culprit here.
Jasper was running on port 5432 and Postgres 9.3 was running on port 5433
I knew that it was on port 5433 from install, but I just assumed that if you try and run command prompt commands that it would use the correct port.
So after uninstalling Jasper Reports Server and changing the port number for Posgres 9.3 in the config file to 5432, I restarted my PC and it worked.
I have an application (APP1) which can only be executed by a user with root privileges but not by root.
Hence I have created another user root1 :
adduser -u 0 -o -g 0 -G 0,1,2,3,4,6,10 -M root1
And then when I am trying to assign a password to this user I get an authentication failure.
[root]# passwd root1
Changing password for user root1.
New UNIX password:
BAD PASSWORD: it is based on a dictionary word
Retype new UNIX password:
passwd: Authentication failure
I looked up a lot on google and tried lot of things suggested but none of them resolved this error.
Could you please help me in resolving the above error, so that I can login to the system using root1 to execute the application(APP1).
Thanks,
The problem is your password. You cannot change the super user password to something really easy and guessable like "qwerty".
Also, Red Hat has a nice article about password security.
