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the product is no longer active in Red Hat Bugzilla.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.

A grab bag of thoughts on the OpenSSH chapter of the RHEL 6.5 Deployment Guide. Ignore as you wish.
* Intro: In addition to telnet and rsh, I might mention rlogin as something ssh can replace -- lots of people will be familiar with rlogin.
* Intro: Claims that openSSH requires openSSL. Really? I don't see that dependency if I run "rpm -q --whatrequires openssl". Are you sure about this?
* Is there any point mentioning "slogin", which is simply a symlink to ssh?
* Section 13.2.2:
"chkconfig sshd on
This will enable the service for all runlevels."
I'm sure you know that's not true. :-) Levels 2,3,4,5. Not 1.
* Section 13.3, "To connect to an OpenSSH server from a client machine, you must have the openssh-clients and openssh packages installed." Since openssh is a package dependency of openssh-clients, it seems unnecessary to tell the reader to install it.
* Section 13.4.1, X11 Forwarding, doesn't distinguish between trusted and untrusted forwarding, which might confuse some readers.
I think that's all.
