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 Anderson Sasaki 2020-04-06 15:35:02 UTC
Description of problem:
The libssh server configuration file (/etc/libssh/libssh_server.config) includes the OpenSSH server configuration file, meaning that changes made to the OpenSSH server configuration will affect the libssh based server applications.

It is not always true that changes in the OpenSSH server configuration file should affect libssh server applications, specially regarding the keys to be used. It is desired that keys are kept independent between different servers.

This bug is about removing the inclusion of the OpenSSH server configuration file from the libssh server configuration file.

Version-Release number of selected component (if applicable):
libssh-8.2.0

How reproducible:
100%

Steps to Reproduce:
1. $cat /etc/libssh/libssh_server.config

Actual results:
# Parse system-wide crypto configuration file
Include /etc/crypto-policies/back-ends/libssh.config
# Parse OpenSSH configuration file for consistency
Include /etc/ssh/sshd_config

Expected results:
File does not contain "Include /etc/ssh/sshd_config"
