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 Patrik Kis 2014-06-05 12:28:39 UTC 
Description of problem:
Part of the content of openssh-server package moved to openssh-keycat in RHEL-7.0. I can see two possible solutions for this:
1/ openssh-keycat should be installed by upgrade tool automatically if openssh-server is installed on RHEL-6.O
 + we can be sure that nothing will be missing after the upgrade
 - if customer did not use keycat in RHEL-6 there will be an extra package installed 
2/ warn customer about the risk
 + no extra package installed if not used
 - customer may overlook the warning

I'm personally inclined to the first solution.

Version-Release number of selected component (if applicable):
preupgrade-assistant-contents-users-0.5.9-1.el6.noarch
preupgrade-assistant-1.0.2-24.el6.x86_64

How reproducible:
always

Steps to Reproduce:

RHEL-6:
# rpm -q openssh-server
openssh-server-5.3p1-94.el6.x86_64
# rpm -ql openssh-server |grep keycat
/etc/pam.d/ssh-keycat
/usr/libexec/openssh/ssh-keycat
/usr/share/doc/openssh-server-5.3p1/HOWTO.ssh-keycat


RHEL-7.0:
[root@rhel7 ~ ]# rpm -q openssh-keycat
openssh-keycat-6.4p1-8.el7.x86_64
[root@rhel7 ~ ]# rpm -ql openssh-keycat
/etc/pam.d/ssh-keycat
/usr/libexec/openssh/ssh-keycat
/usr/share/doc/openssh-keycat-6.4p1
/usr/share/doc/openssh-keycat-6.4p1/HOWTO.ssh-keycat
[root@rhel7 ~ ]#
Comment 1 Ondrej Vasik 2014-06-05 12:45:19 UTC 
Adding Petr to cc... Petr, what do you think? Should we create module for it? If so, I tend to option 2, with medium risk informing user about the package split - so he can install it after upgrade, if keycat was in use on his system.
Comment 2 Petr Lautrbach 2014-06-05 12:58:56 UTC 
If users followed HOWTO.ssh-keycat, they would be also affected by the change of AuthorizedKeysCommandRunAs from rhel-6 to AuthorizedKeysCommandUser in rhel-7 which is already covered by the content. So I personally would use option 2 - warn users about the change and let them install openssh-keycat package after upgrade, or maybe there can be a check if there's 'AuthorizedKeysCommand /usr/libexec/openssh/ssh-keycat' in the original sshd_config, install openssh-keycat during postupgrade phase.

IMHO this is a good idea. Why don't automate if we can.
And if there is no AuthorizedKeysCommand in sshd_config, we could warn. Although, I don't know where else ssh-keycat can be used.
Comment 8 Petr Stodulka 2014-10-27 11:52:36 UTC 
For application of this content you need install openssh-server..
When you have set "AuthorizedKeysCommand /usr/libexec/openssh/ssh-keycat" inside /etc/ssh/sshd_config, openssh-keycat should be installed automatically on rhel-7 system by postupgrade script and content should be marked as "FIXED" with slight risk with message. In other case warning message will be printed with medium risk and openssh-keycat shouldn't be installed on RHEL-7 system.
