Red Hat Bugzilla – Bug 64293
RFE: allow an override of the /etc/nologin testing.
Last modified: 2016-09-28 16:56:43 EDT
Currently sshd tests for /etc/nologin *both* through the pam and on its own.
This is very annoying - one assumes that it's possible to override the tests by
modifying the /etc/pam.d/sshd, but then it turns out that the pam_nologin in
/etc/pam.d/sshd is redundant and that sshd does the testing itself and there is
no way to override it.
In short, this RFE is for:
1) Configuration option to override the /etc/nologin testing in sshd itself (see
also bug #47298).
2) Change in the default config shipped by RedHat to have the override turned on.
P.S. According to bug #54108, the pam_nologin needs to be moved from auth to
account in order to work properly even with the RSA authentication.
I concur this should be fixed. This is not how Red Hat Linux 9 behaved
and having upgraded to Fedora Core 2 from RHL9 I was bitten by this.
This also appears to be a problem in RHEL 3. In my opinion there
shouldn't be a toggle switch in sshd; the check should be done only in
Without solving bug 54108 the nologin processing shouldn't be removed. Also
note, that the contents of /etc/nologin should be dumped on client's terminal.
This isn't/cannot be the case of using pam for nologin processing.
Adding a new configuration option is also not good without having it in upstream
portable OpenSSH first so please report it to http://bugzilla.mindrot.org/.
OK, done that for you even with a patch.
If upstream accepts it we'll see.
