RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023.

Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit).

Remote ssh login fail with "Permission denied"
Version-Release number of selected component (if applicable):

How reproducible:
100%
Steps to Reproduce:
1. After the OS successfully installed, remote ssh login the system, it will fail with permission denied:
# ssh root.122.155
root.122.155's password:

root.122.155's password:
root.122.155: Permission denied (publickey,gssapi-keyex,gssapi-with-mic,password).
2. After logging in the system locally or by the console, check the sshd setting:
[root@localhost ~]# grep PermitRoot /etc/ssh/sshd_config
#PermitRootLogin prohibit-password
# the setting of "PermitRootLogin without-password".
[root@localhost ~]# rpm -qf /etc/ssh/sshd_config
openssh-server-8.6p1-5.el9.x86_64
[root@localhost ~]# rpm -V openssh-server
[root@localhost ~]# echo $?
0
3. Update the configure file, and try remote ssh login:
[root@localhost ~]# echo "PermitRootLogin yes" >> /etc/ssh/sshd_config
[root@localhost ~]# systemctl restart sshd
After this setting, we can login the system by ssh.

Check the man page, the default value is "prohibit-password", the result is as expected.
PermitRootLogin
Specifies whether root can log in using ssh(1). The argument must be yes, prohibit-password, forced-commands-only, or no. The default is prohibit-password.
