Not able to connect to redhat server using filezilla and new test user

rgundabhat · 03-07-2012, 03:59 PM

I have created a new test user on the redhat server and I am using this user in filezilla to connect to the server.

error@var/log/secure
moodletest sshd[8066]: fatal: Read from socket failed: Connection reset by peer

Also, I am able to connect using root account but not with this new account. I created this account using useradd command. No password has been assigned to this acocunt.

Please help

untill and unless you give a password to your account it is not activated and cannot be used

I realized about the passwrd and assigned one.
Here is the story now,
1. Created a user using below command so that user should get access to the shell but only to a folder to drop files.
useradd -s /sbin/nologin -d /var/www/html webuser
2. assigned a password to the user
3. made user the owner of the folder to which he needs the access.
4. in the file zilla when I try to connect FTP (selected FTP in the protocol drop down of the site manager). I get the below error in the filezilla. No other error is displayed on the server at tail -f /var/log/secure

Status: Connecting to xxxxxxxx.111...
Status: Connecting to xxxxxxxxx:21...
Status: Connection established, waiting for welcome message...
Response: 220 (vsFTPd 2.0.5)
Command: USER webuser
Response: 331 Please specify the password.
Command: PASS *******
Response: 530 Login incorrect.
Error: Critical error
Error: Could not connect to server

5. In the filezilla when I user SFTP protocaol (selected FTP in the protocol drop down of the site manager)I get the below errors

@ file zilla

Status: Connecting to 192.xxxxxx...
Response: fzSftp started
Command: open "webuser@xxxxxxxx" 22
Command: Pass: *******

@ linux server tail -f /var/log/secure

Suggestions please. All I want to to create a user and provide FTP access to a certain folder on the linux server.

why have you assigned a nologin shell for the user instead of /bin/bash?

Hi,

no need to assign bash shell, there's trouble with your vsftpd PAM module.

Check your PAM authorization file if you're doing with LDAP I'm sorry I don't know how to help.
How does your /etc/pam.d/vsftpd PAM config file look like:

Code:

auth       required     pam_listfile.so item=user sense=deny file=/etc/vsftpd/ftpusers onerr=succeed
auth       required     pam_shells.so
auth       include      system-auth
account    include      system-auth
session    include      system-auth
session    required     pam_loginuid.so

good luck
