Run from "make check" if "t_client.rc" is found in workdir or srcdir
(copy t_client.rc-sample, fill in specifics for your test server)
How does it work?
- you run "sudo make check" (needs root access to configure tun if!)
- t_client.sh reads t_client.rc from current dir or ${srcdir}
- t_client.rc defines a number of "test suffixes" to run (could be
"1" "2" "3" or "p2m", "p2p", "special" or whatever you like), and
for each suffix, there's config variables to specify
- how to call OpenVPN
- which hosts to ping for IPv4 and IPv6 when OpenVPN is up
(and actually before starting OpenVPN - to make the test more
meaningful, I have decided that the test hosts must not ping
before the tests starts)
- which addresses must show up in the output of "ifconfig" after
OpenVPN has started
- all variables except OPENVPN_CONF_<x> are optional
(this should all be fairly obvious from looking at t_client.rc-sample)
- the script wants to connect to a well-defined OpenVPN server that
will assign well-known IPv4 (and IPv6) addresses, have well-defined
pingable addresse, etc. - so you need to setup the test server before
the script is useful for you. (Whether you use certificates or
username/password is up to you, you could even mix and match - run
one test with certs, and one with user/pass against different target
ports... :-) )
[we *could* run a "reference server" somewhere and ship a sample
t_client.rc + cert so that users could use this right away, but I
do not currently have the resources to run such a public server]
- whatever the script does is logged to a newly created directory
below the current directory (openvpn output, ifconfig+route before
starting OpenVPN, while running it, after ending it)
- important: at least on NetBSD and OpenBSD, the script will print
one failure, because the tun0 interface created is not destroyed
after openvpn ends. For OpenBSD, I have changed close_tun() to
do so ("ifconfig tun0 destroy"), for NetBSD I have not yet changed
anything - but I strongly believe that the output of "ifconfig+route"
should be reverted to exactly how it looked like before OpenVPN
was started, so I consider this a bug in the NetBSD-specific bits
of OpenVPN (and will look into this).
- the test framework has been tested on Linux, NetBSD and OpenBSD.
It *should* work fine on FreeBSD and Solaris.
It works on MacOS X (but the output looks funny, because /bin/sh
does not implement "echo -e" - need to add configure trickery)
It will *not* work on Windows yet - I haven't looked into what's
needed to make it work (background processes and signals in mingw
bash?), maybe it's as easy as adding the necessary "ipconfig" and
"netsh" commands to print interface + routing config...
- I have only tested "connect via IPv4 transport, use IPv4+IPv6 payload",
but the framework is generic enough that "connect via IPv6 transport"
should work just fine (just setup OPENVPN_CONF_x accordingly in the
t_client.rc).
- this is neither finished nor pretty, but it helps me a *lot* in
quickly testing whether I broke anything when fiddling system-dependent
code (tun.c, route.c) across multiple build hosts - so I hope this
is going to be fairly useful to Samuli and the buildbot :-)

which was started in the sf.net bug tracker:
<http://sourceforge.net/tracker/?func=detail&aid=2078470&group_id=48978&atid=454719>
The implemented solution is to give a warning for each of the different script hooks
available. The last configured script will override any earlier configured scripts,
to ensure that the command line can override the configuration file.

Problem: using --ping and --inactive together partially defeats the
point of using --inactive as periodic ping packets are counted as
activity. Here is the original discussion:
http://article.gmane.org/gmane.network.openvpn.devel/3676
It turns out that "activity" is detected and recorded in two places
in the code, both in forward.c: in process_outgoing_tun() for received
packets, after they've been decrypted and sent to the TUN device; and
in process_outgoing_link(), after they've been encrypted and written
to the network socket.
In the first case we can be sure that packets that get so far are
really due to user activity, whereas in the second case there can be
non-user packets (like OpenVPN's internal ping packets, and TLS control
packets), and those should not be counted as activity as they are not
coming from the user.
So a need arises to detect those control packets and not count them as
activity for the purposes of --inactive. Unfortunately, at that stage
packets are already compressed and encrypted, so it's not possible to
look into them to see what they are. However, there seems to be a
convention in the code that packets whose buffer length in the context_2
structure is 0 should be ignored for certain purposes. TLS control
packets follow that convention already, so this patch makes a small
change in the code that generates the ping packets to set their buffer
length to 0 as well.
Finally, the call to register_activity() in process_outgoing_link() is
made conditional to the buffer length being > 0.
According to my tests, now --inactive behaves correctly according to
the configured parameters (time or time+bytes) even when --ping is
being used.
forward.c:
Call register_activity() in process_outgoing_link() only if the
packet is not a ping or TLS control packet.
openvpn.8:
Updated the description of --inactive to describe the new semantics.
ping.c:
Set c->c2.buf.len = 0 after the ping packet has been generated and
encrypted.
Test routine is described here:

Solves bug ticket 13
<https://community.openvpn.net/openvpn/ticket/13>
When the client sends PUSH_REQUESTS, it waits until the server sends PUSH_REPLY.
If the server do not have anything to push to the client nothing happens. The
client will then regularly send new PUSH_REQUESTS until it gets an answer, which
results in not completing the connection negotiation.
This patch makes the server send an empty PUSH_REPLY when it has nothing to more
to push to the client.

contrib/OCSP_check/OCSP_check.sh:
I discovered that, quite surprisingly, the exit status of "openssl ocsp"
is 0 even if the certificate status is "revoked". This means that the
logic of the script needs to be rewritten so that it parses the output
returned by the query and explicitly looks for a
"0x<serial number>: good"
line, and exit if either the command has a non-zero exit status, or the
above line is not found.
Doing that portably without bashisms requires some juggling around, so
perhaps the code is slightly less clean now, but it does have many
comments.

Patch arrived from Davide Brini:
- No more bashisms (AFAICT). Should work with any POSIX-compatible shell
(which means "almost all reasonably recent shells"), though I've only tested
with bash and dash.
- Unnecessary calls to external tools (sed) removed
- Manages multiple DNS and DOMAIN options. Each DNS option becomes a
"nameserver" line in the new resolv.conf (up to a maximum of 3). If there's a
single DOMAIN option, it becomes a "domain" line in resolv.conf; otherwise,
all the domains are listed in a "search" line in resolv.conf (eg "search
foo.com example.net").
- Client.up renames the existing resolv.conf and creates a brand new one;
client.down restores it from the saved copy when the VPN terminates (the usual
rules about running as root apply). This is how Gentoo does that; the old
scripts instead added/removed some lines at the beginning of the file, which
looks a less clean approach to me. The rename approach also dramatically
simplifies and shortens client.down, as you'll see.
- Uses resolvconf if it's available (detected by the presence of
/sbin/resolvconf) rather than writing to resolv.conf directly. Not sure
whether this is a Linux-only thing or other systems use it though.
Script has been smoke tested on Fedora 12 with OpenVPN 2.1.1 without
the resolvconf package , and in addition Debian Lenny with
OpenVPN 2.1_rc11 according to the patch.

By hardening the create_temp_filename() function to check if the generated

files set before calling the script, it should become even more difficult to
exploit such a scenario.
After a discussion on the mailing list, Fabian Knittel provided an enhanced

This patch also renames create_temp_filename() to create_temp_file(), as this

There was a debian bugreport which was filed in 2005 . It was patched but
it seems that nobody forwarded the patch to the openvpn project itself.
The problem is quite simple:
The dashes for options (the double dashes) are not escaped. This causes
trouble in relationship with utf-8 .
Since the bugreport was closed it was patched within the debian/ubuntu
packages itself. I've attached the patch to get it atleast reviewed by the
openvpn project itself.

Many of the scripts in the openvpn source have their shell set to
/bin/bash, but only two use bash features. The attached patch (against
openvpn-2.1_rc9) sets the shell on the rest of the scripts to /bin/sh for
better portability. The only scripts that actually require bash are
contrib/pull-resolv-conf/client.{up,down} ; they use the ${!var} variable
indirection feature.

I am running a multihomed host where 'local <extip>' must be specified
for proper operation. Unfortunately, this implies 'lport 1194' or
another static port.
This causes problems with stateful firewalls which register the host/port
pairs in the internal connection tracking table. On ungraceful reconnects,
the new TCP connection will have same the host/port pairs but unexpected
sequence numbers. The new connection will be assumed as invalid hence and
be dropped.
It would be nice when local port can be configured to be bound to a
random port number. After reading code,
| else if (streq (p[0], "lport") && p[1])
| ...
| port = atoi (p[1]);
|- if (!legal_ipv4_port (port))

With --verb 5, openvpn logs a single letter (rwRW) for each package
received or sent. I recently ran into a problem with the tun device on
Linux where the read from that device returned 0. Unfortunately this was
also logged as "r", which made me assume that openvpn had received
something, while it actually hadn't.
(See https://dev.openwrt.org/ticket/6650 for the bug that made me find out
about this problem with openvpn.)
I'm attaching a patch which prevents openvpn from logging "r" or "R" when
it didn't actually read anything. This is against openvpn 2.1-rc20, but
probably still applies to the most recent version.

This patch should be easy to process.
A resubmission of the patch sent to this list on 04/23/2009.
The patch changes the verify-cn script sample
to be used with --tls-verify so that instead of having
to hardcode a cn to verify in the OpenVPN configuration file
the allowed cns may be written into a separate file.
This makes the process of verifying cns a whole
lot more dynamic, to the point where it is useful
in the real world.
One problem with this patch is that it is backwards
incompatible. I did not bother keeping the original
calling interface as A) it's a sample script, and B) the
original's functionality seems useless
and equalivant functionality is easily available
with the new script.
The problem with the original is that there seems
little point in verifying a client's cn when all
the clients share one cn, as would have to be
the case when the cn is hardcoded into the openvpn
config file.
This patch applies against the testing allmiscs branch,
and should apply against any of the other testing
branches as well.

contrib/OCSP_check/OCSP_check.sh:
New barebone script to demonstrate how to use $tls_serial_{n}
to perform simple OCSP queries using OpenSSL command line
"openssl ocsp". Minimal sanity checks to fail if user tries to
use it without customizing.
openvpn.8:
Added some notes about $tls_serial_{n} format and usage to the
existing description.
ssl.c:
correctly manage and export serial numbers of any size (as
parsed by OpenSSL) into the environment. Set to empty string
in case of errors, as 0 and negative numbers are all possible
(although illegal) certificate serial numbers. Use an OpenSSL
BIO object to do the job. Conforms to coding style guidelines.

Patch arrived from Davide Brini:
- No more bashisms (AFAICT). Should work with any POSIX-compatible shell
(which means "almost all reasonably recent shells"), though I've only tested
with bash and dash.
- Unnecessary calls to external tools (sed) removed
- Manages multiple DNS and DOMAIN options. Each DNS option becomes a
"nameserver" line in the new resolv.conf (up to a maximum of 3). If there's a
single DOMAIN option, it becomes a "domain" line in resolv.conf; otherwise,
all the domains are listed in a "search" line in resolv.conf (eg "search
foo.com example.net").
- Client.up renames the existing resolv.conf and creates a brand new one;
client.down restores it from the saved copy when the VPN terminates (the usual
rules about running as root apply). This is how Gentoo does that; the old
scripts instead added/removed some lines at the beginning of the file, which
looks a less clean approach to me. The rename approach also dramatically
simplifies and shortens client.down, as you'll see.
- Uses resolvconf if it's available (detected by the presence of
/sbin/resolvconf) rather than writing to resolv.conf directly. Not sure
whether this is a Linux-only thing or other systems use it though.
Script has been smoke tested on Fedora 12 with OpenVPN 2.1.1 without
the resolvconf package , and in addition Debian Lenny with
OpenVPN 2.1_rc11 according to the patch.

By hardening the create_temp_filename() function to check if the generated

files set before calling the script, it should become even more difficult to
exploit such a scenario.
After a discussion on the mailing list, Fabian Knittel provided an enhanced

Many of the scripts in the openvpn source have their shell set to
/bin/bash, but only two use bash features. The attached patch (against
openvpn-2.1_rc9) sets the shell on the rest of the scripts to /bin/sh for
better portability. The only scripts that actually require bash are
contrib/pull-resolv-conf/client.{up,down} ; they use the ${!var} variable
indirection feature.

I am running a multihomed host where 'local <extip>' must be specified
for proper operation. Unfortunately, this implies 'lport 1194' or
another static port.
This causes problems with stateful firewalls which register the host/port
pairs in the internal connection tracking table. On ungraceful reconnects,
the new TCP connection will have same the host/port pairs but unexpected
sequence numbers. The new connection will be assumed as invalid hence and
be dropped.
It would be nice when local port can be configured to be bound to a
random port number. After reading code,
| else if (streq (p[0], "lport") && p[1])
| ...
| port = atoi (p[1]);
|- if (!legal_ipv4_port (port))

With --verb 5, openvpn logs a single letter (rwRW) for each package
received or sent. I recently ran into a problem with the tun device on
Linux where the read from that device returned 0. Unfortunately this was
also logged as "r", which made me assume that openvpn had received
something, while it actually hadn't.
(See https://dev.openwrt.org/ticket/6650 for the bug that made me find out
about this problem with openvpn.)
I'm attaching a patch which prevents openvpn from logging "r" or "R" when
it didn't actually read anything. This is against openvpn 2.1-rc20, but
probably still applies to the most recent version.

This patch should be easy to process.
A resubmission of the patch sent to this list on 04/23/2009.
The patch changes the verify-cn script sample
to be used with --tls-verify so that instead of having
to hardcode a cn to verify in the OpenVPN configuration file
the allowed cns may be written into a separate file.
This makes the process of verifying cns a whole
lot more dynamic, to the point where it is useful
in the real world.
One problem with this patch is that it is backwards
incompatible. I did not bother keeping the original
calling interface as A) it's a sample script, and B) the
original's functionality seems useless
and equalivant functionality is easily available
with the new script.
The problem with the original is that there seems
little point in verifying a client's cn when all
the clients share one cn, as would have to be
the case when the cn is hardcoded into the openvpn
config file.
This patch applies against the testing allmiscs branch,
and should apply against any of the other testing
branches as well.
It works for me. I've tested it throughly but not
used it extensively in production.

This patch should be easy to process.
A resubmission of the patch sent to this list on 04/23/2009.
The patch changes the verify-cn script sample
to be used with --tls-verify so that instead of having
to hardcode a cn to verify in the OpenVPN configuration file
the allowed cns may be written into a separate file.
This makes the process of verifying cns a whole
lot more dynamic, to the point where it is useful
in the real world.
One problem with this patch is that it is backwards
incompatible. I did not bother keeping the original
calling interface as A) it's a sample script, and B) the
original's functionality seems useless
and equalivant functionality is easily available
with the new script.
The problem with the original is that there seems
little point in verifying a client's cn when all
the clients share one cn, as would have to be
the case when the cn is hardcoded into the openvpn
config file.
This patch applies against the testing allmiscs branch,
and should apply against any of the other testing
branches as well.
It works for me. I've tested it throughly but not
used it extensively in production.

"openvpn login OURDOMAIN+USERNAME password PASSWORD"
Finally I turned on more verbose logging and found that the plugin did
not recognize "USERNAME" as something to replace, because it expected
the string to be surrounded by whitespace. I wrote the following patch
to correct this. I hope you find it useful,

This is a modified version of a patch sent to the sf.net
patch tracker:
<http://sourceforge.net/tracker/?func=detail&aid=2491190&group_id=48978&atid=454721>
After having disucssed this patch on IRC (#openvpn-discussions)
March 4, 2010, it was decided to accept this patch when not modifying
TARGET_* defines through out the code. Further, in a mail comment
Alon Bar-Lev had some other comments of what would be needed to be done.
Mail reference:
<http://thread.gmane.org/gmane.network.openvpn.devel/3176>
This patch has been tested by bootstrapping the code on a RHEL4.6 box.
with the following autotools packages installed:
autoconf-2.59-5
automake-1.9.2-3
libtool-1.5.6-4.EL4.2
It builds cleanly and 'make check' passes.

There was a debian bugreport which was filed in 2005 . It was patched but
it seems that nobody forwarded the patch to the openvpn project itself.
The problem is quite simple:
The dashes for options (the double dashes) are not escaped. This causes
trouble in relationship with utf-8 .
Since the bugreport was closed it was patched within the debian/ubuntu
packages itself. I've attached the patch to get it atleast reviewed by the
openvpn project itself.
See <http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=296133> for details.

Many of the scripts in the openvpn source have their shell set to
/bin/bash, but only two use bash features. The attached patch (against
openvpn-2.1_rc9) sets the shell on the rest of the scripts to /bin/sh for
better portability. The only scripts that actually require bash are
contrib/pull-resolv-conf/client.{up,down} ; they use the ${!var} variable
indirection feature.

I am running a multihomed host where 'local <extip>' must be specified
for proper operation. Unfortunately, this implies 'lport 1194' or
another static port.
This causes problems with stateful firewalls which register the host/port
pairs in the internal connection tracking table. On ungraceful reconnects,
the new TCP connection will have same the host/port pairs but unexpected
sequence numbers. The new connection will be assumed as invalid hence and
be dropped.
It would be nice when local port can be configured to be bound to a
random port number. After reading code,

With --verb 5, openvpn logs a single letter (rwRW) for each package
received or sent. I recently ran into a problem with the tun device on
Linux where the read from that device returned 0. Unfortunately this was
also logged as "r", which made me assume that openvpn had received
something, while it actually hadn't.

or "dhcp-renew" options were combined with "route-gateway dhcp".
The problem is that the IP Helper functions for DHCP release and
renew are blocking, and so calling them from a single-threaded
client stops tunnel traffic forwarding, and hence breaks
"route-gateway dhcp" which requires an active tunnel. The fix is
to call the IP Helper functions for DHCP release and renew from
another process.

This feature is intended to make UDP clients respond the same as TCP
clients in the case where the server issues a RESTART message in
order to force the client to reconnect and pull a new options/route
list.

to clients, including routes. Previously, all pushed options needed
to fit within a 1024 byte options string.
Remember that to make use of this feature to allow many routes to
be pushed to clients, the client config file must specify the
max-routes option, and the number of pushed routes cannot exceed
this limit. Also, both server and client must include this commit.

file or pulled from a server) can now be configured via the new
"max-routes" directive.
Previously, the limit was set to 100 and fixed by a compile-time
constant. Now the limit is dynamic and can be modified by the
"max-routes" directive. If max-routes is not specified, the default
limit is 100.
Note that this change does not address the maximum size of the
pushed options string sent from server to client, which is still
controlled by the TLS_CHANNEL_BUF_SIZE compile-time constant.

after connection initiation rather than 0 seconds after.
Successive PUSH_REQUEST messages after the first will continue to be
sent at 5 second intervals until a response is received. This tends
to speed up the client connection sequence by 4 seconds because the
first PUSH_REQUEST message is usually sent too soon and is dropped,
causing a wait of 5 seconds until the next PUSH_REQUEST message is
sent.
