[CentOS] GnuPG 2.0.16?

[Kay Schenk]

Hello all --

Does anyone know where I can find GnuPG 2.0.16 for CentOS 6.9 32-bit? 
I've already looked in the normal repos.


I have 2.0.14 now and my Enigmail addon has stopped working.

Thanks.

A (192.168.1.10)
S (192.168.1.20)

I do not see tftp traffic is leaving from S

A:~$ tftp
(to) 192.168.1.20
tftp> get file
Transfer timed out.

As you can see no pkt is leaving. If it were leaving S, but A were not
receiving then I would think firewall
is dropping it.

[ S ~]$ sudo tcpdump -A -nniany host 192.168.1.10

A STATEFUL firewall with “ip any any” can and will still block asymmetric
communications due to the firewall keeping track of state (hence tha name
stateful firewall).

Tcpdump on your servers /other/ NICs and you’ll see the tftp traffic
leaving your server on some other NIC (probably on with the default route).

The upstream firewall will then block the tftp response if it never saw the
tftp request (due to asymmetry).

We are using the OpenLDAP + pam_ldap / sssd solution in
several smaller networks (up to ~40 Linux clients), but
I think it should scale well for larger networks, too.

The OpenLDAP solution can also support Samba as domain controller,
if you have to support windows clients, too.

- From that point on we usually integrate other services like
an IMAP server (we use Cyrus IMAP), groupware server (we use SOGo)
and many other services which suport LDAP authentication.
You can apply LDAP password policies, too.

We use GOSa (or it's successor FusionDirectory, see 
https://www.fusiondirectory.org/)
as web frontend, so the users can change their passwords, mail settings etc. on
their own (if they are given the rights to do so)

With all that you get a nice, easy to manage, well integrated and
secure network with a central authentication service all with open
source software!

It should run with almost all modern linux distributions, even mixed
together in the same network.

HTH

I'm planning to test this very soon, probably during the next week, and
I'll report back.

According to this:

it's still possibly.
