[Openswan Users] pluto failure

[Marco Berizzi]

Hello.
I'm running OpenSWAN 2.3.1 on Slackware 10.1
I have manually patched (make kpatch) linux
vanilla 2.4.30
Gcc is 3.3.5, glibc 2.3.4
Today, after about 10 uptime days pluto has
been crashed.
Here is syslog:

Hi, folks,

I'm trying to configure a IPSec/L2TP linux client, but I'm facing some
little troubles.

Basically, the IPSec tunnel is stablished successfully, but the L2TP/PPP
authentication fails.

The first problem is that, looking at /var/log/messages in my VPN Server, it
says that the user is my client's hostname and not a real user that I want.

Then, I configure my options.l2tpd file on the VPN Server to not perform
authentication (noauth). Then, the ppp0 appears on both sides, but the
server can't determine the Ethernet address of my client with the "proxyarp"
option.

Anybody could help me, please?

Regards,

Alan Tamer Vasques

You can specify the 'user' option in options.l2tpd.
See 'man pppd'.

Both sides run Linux? I would not recommend L2TP for such a setup.
IPsec without L2TP is easier to use.

Sorry for interrupting the topic but I think it's right time to ask, how
do you handle issues with MTU when using plain IPSec?
If you had L2TP/PPP, you could set an MTU in ppp to some lower value to
balance the overhead added by IPSec protocol encapsulation. I noticed
that xp native (L2TP/PPP) clients had no MTU problem. Correct me if I am
wrong.

I configured a tunnel between two linux hosts running OpenSwan 2.2.0
with plain IPSec, and no other layer 2 protocols, and I had big troubles
to make rdp/vnc/smb connections work, while other light connections
(example: telnet, ssh) worked fine.

I finally used the MSS target in the iptables script, and it all worked
fine.
Unfortunatelly I am not able to check if Path-MTU (as I remember it is
icmp [type 3, code 4]) would also work.
If you open a firewall for this icmp traffic, would it be enough?

I'd like to ask how you handle such problems.

Sorry, you're asking the wrong guy. I have not had MTU problems
(fortunately) so I can't really help.

so you are the lucky one :)

How about using 'ifconfig eth0 mtu 1400' or some other value?

that's not an option; there is a lot of other traffic on the IPSec link

I just want to know how it should be solved best - establish
PPP/L2TP/IPSec connections like xp clients do, or would be enough to let
icmp [3,4] packets go through, so Path-MTU would be used, or... what else?

I used the MSS target in the iptables script, and it worked, but I think
it isn't the right way, bacause it does not solve all problems, just TCP
sessions.

So, who else had the problem, and would like to share the knowledge of
solving it?

I have a similar setup (difference is in dist. used) and Paul Wouters told
me that this problem is solved in CVS HEAD. It will be corrected in Openswan
2.3.2.
I have not tested yet but I'll do the tests very soon.

Done.

Hi folks,

I've compiled a new kernel (2.6.12-rc3) from source on a FC3 system.
Everything went well,.but when I try to compile the openswan KLIPS module
against the new kernel source, I get the following error:

/tmp/mod26/pfkey_v2.c: In function `pfkey_create':
/tmp/mod26/pfkey_v2.c:654: warning: passing arg 3 of `sk_alloc' makes
pointer from integer without a cast
/tmp/mod26/pfkey_v2.c:654: warning: passing arg 4 of `sk_alloc' makes

/tmp/mod26/pfkey_v2.c: In function `pfkey_get_info':
/tmp/mod26/pfkey_v2.c:1486: error: structure has no member named `sk_zapped'

Has anyone seen an error like this? Is that something I've done wrong at the
kernel compilation? Or is that just my incredible stupidity at work?


Giovani

[Giovani Moda - MR Informática]

Hey,

I've found this in a forum. I don't really know if it has something to do
with this error, but it appears to me that has been some changes in how
sk_alloc works in these new kernels.

Take a look:

-----------------------------------------------------------------------------------------------------------------------------------------------------------------
Hi everybody,

the 26th of March 2005 Arnaldo Carvalho de Melo commited a quite big change
to
sk_alloc:

ChangeSet 1.2181.42.2 2005/03/26 20:04:49 ***@xxxxxxxxxxxxxxxxxxxxxx
[NET] make all protos partially use sk_prot

sk_alloc_slab becomes proto_register, that receives a struct proto not
necessarily
completely filled, but at least with the proto name, owner and obj_size
(aka proto
specific sock size), with this we can remove the struct sock sk_owner and
sk_slab,
using sk->sk_prot->{owner,slab} instead.

This patch also makes sk_set_owner not necessary anymore, as at sk_alloc
time we
have now access to the struct proto onwer and slab members, so we can bump
the
module refcount exactly at sock allocation time.

Another nice "side effect" is that this patch removes the generic
sk_cachep slab
cache, making the only last two protocols that used it use just kmalloc,
informing
a struct proto obj_size equal to sizeof(struct sock).

Ah, almost forgot that with this patch it is very easy to use a slab
cache, as it is
now created at proto_register time, and all protocols need to use
proto_register,
so its just a matter of switching the second parameter of proto_register
to '1', heck,
this can be done even at module load time with some small additional
patch.

Another optimization that will be possible in the future is to move the
sk_protocol
and sk_type struct sock members to struct proto, but this has to wait for
all protocols
to move completely to sk_prot.

This changeset also introduces /proc/net/protocols, that lists the
registered protocols
details, some may seem excessive, but I'd like to keep them while working
on further
struct sock hierarchy work and also to realize which protocols are old
ones, i.e. that
still use struct proto_ops, etc, yeah, this is a bit of an exaggeration,
as all protos
still use struct proto_ops, but in time the idea is to move all to use
sk->sk_prot and
make the proto_ops infrastructure be shared among all protos, reducing one
level of
indirection.

The same change needs to be propagated to cman-kernel (probably more,
but i am working on one module at a time).
Here is a preliminary patch that works for me.

Please review before applying.

You will need to use CVS HEAD for that kernel, and perhaps it is currently
even still broken in cvs too.

Hi. This morning my OpenS/WAN gateway has
been crashed.
OpenS/WAN doesn't start anymore.
(I haven't rebooted this system, I have replaced
with another one).
This is the message starting OpenS/WAN:

I'm running OpenSWAN 2.3.1 on Slackware 10.1
I have manually patched (make kpatch) linux
vanilla 2.4.30
Gcc is 3.3.5, glibc 2.3.4
Today, after about 10 uptime days pluto has
been crashed.

Please add dumpdir=/tmp to config setup and restart openswan. When the
failire happens again, you should have a core file. Use gdb on it to give
us a backtrace.

Can you add dumpdir=/tmp in ipsec.conf's config setup section, and produce
a core file and run gdb on it to get a backtrace?

Thanks,
