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 of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. 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). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.
Description of problem:
When reset remote access(or reset password), the vmaccess.py do twice sshd_config backup executions:
1. Backup sshd_config then set "ChallengeResponseAuthentication no" in the sshd_config
2. Backup sshd_config then put a default sshd_config file into the VM
So there should be 2 backup files(named like sshd_config_2016-11-02T06:17:05Z) in the /etc/ssh/ folder. But there's only one backup file. Because the backup file name use the time string, and the twice backup execution are too close(in 1 second) that the time strings are the same, so the second backup file covers the first backup file.
Version-Release number of selected component (if applicable):
VMAccess-1.4.6.0
WALinuxAgent-2.2.0(Isn't about WALA)
RHEL Version: RHEL-7.3
How reproducible:
100%
Steps to Reproduce:
1. Prepare a VM. Modify the value in the /etc/ssh/sshd_config, set "ChallengeResponseAuthentication yes".
2. Run "reset remote access" from Azure portal.
3. Check the "ChallengeResponseAuthentication" item inside the sshd_config_* file
Actual Result:
The "ChallengeResponseAuthentication" is "no" inside the backup sshd_config_* file
Expect Result:
The "ChallengeResponseAuthentication" is "yes" inside the backup sshd_config_* file
Additional Info:
None
