Note: This bug is displayed in read-only format because the product is no longer active in Red Hat Bugzilla.

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 Martin Kosek 2013-06-12 16:21:26 UTC

This bug is created as a clone of upstream ticket:
https://fedorahosted.org/freeipa/ticket/3705

When running

{{{
ipa-client-install --ssh-trust-dns
}}}

it effectively prevents the

{{{
GlobalKnownHostsFile /var/lib/sss/pubconf/known_hosts
ProxyCommand /usr/bin/sss_ssh_knownhostsproxy -p %p %h
}}}

from being configured in {{{/etc/ssh/ssh_config}}}. The ipa-client-install man page could be amended to be clear about it, or the behaviour could be changed to always configure both (unless {{{--no-ssh}}} is used).

Comment 1 Namita Soman 2013-06-17 16:55:26 UTC

Will this be a man page change or a configuration update in /etc/ssh/ssh_config ? Please provide steps to verify

Comment 2 Martin Kosek 2013-06-18 08:59:01 UTC

There will be a configuration change in /etc/ssh/ssh_config. When ipa-client-install is run with --ssh-trust-dns, then /etc/ssh/ssh_config will contain both standard

GlobalKnownHostsFile /var/lib/sss/pubconf/known_hosts
ProxyCommand /usr/bin/sss_ssh_knownhostsproxy -p %p %h

but also

VerifyHostKeyDNS yes
