Hello! I have some trouble trying to configure a VPN with two gateways. One of them uses IPSec [FreeSwan/Linux] with a single key, 256bits length, specified in /etc/ipsec.secrets. As FreeSwan manual page says, if i put esp=3des-md5-96, will be used a "64bit IV key (internally generated), a 192bit 3des ekey and a 128bit hmac-md5 akey (RFC2451, RFC2403). The part I miss is: how can i split this key to be able to set up the other gateway with OpenBSD/FreeBSD? Or what must be done to use this single key for encryption and authentication on the xBSD gw? Here is a part from ipsec.conf:
and from ipsec.secrets:
Thanks,
I'm facing a problem interpreting the shared memory key on an AIX machine.
(1) I go to a property file and I see the following:
shm_key = "119112066"
(2) So I now go the command prompt and do this:
ipcs -m | grep 119112066
And, I do not find it. So what I do is to run the... (2 Replies)
Hello,
I'm trying to setup a gateway VPN between two routers across an unsecured network between two local networks. The routers are both linux and I'm using the ipsec tools, racoon and setkey. So far hosts from either local net can successfully ping hosts on the other local net without issue.

Hi, I've used the following way to set ssh public key authentication and it is working fine on Solaris 10, RedHat Linux and SuSE Linux servers without any problem. But I got error 'Server refused our key' on Solaris 8 system. Solaris 8 uses SSH2 too. Why? Please help. Thanks.

Hello.
I am new to this forum and I would like to ask for advice about low level POSIX programming.
I have to implement a POSIX compliant C shared library.
A file will have some variables and the shared library will have some functions which need those variables.
There is one special... (5 Replies)
Hi all,
I have installed Openswan and configured IPSec and works perfect, but for some unknown reasons it stop working. I see that the tunnels are up and established. The route to the destination are added. Everything by the book seems to be ok. But somehow when i start to ping the other side (... (4 Replies)

IPSEC_KLIPSDEBUG(8) [FIXME: manual] IPSEC_KLIPSDEBUG(8)NAME
ipsec_klipsdebug - set KLIPS and MAST debug features and level. Other stacks are not supported.
SYNOPSIS
ipsec klipsdebug
ipsec klipsdebug --set flagname
ipsec klipsdebug --clear flagname
ipsec klipsdebug --all
ipsec klipsdebug --none
ipsec klipsdebug --help
ipsec klipsdebug --version
DESCRIPTION
Klipsdebug sets and clears flags that control various parts of the debugging output of Klips (the kernel portion of FreeS/WAN IPSEC). The
form with no additional arguments lists the present contents of /proc/net/ipsec_klipsdebug. The --set form turns the specified flag on,
while the --clear form turns the specified flag off. The --all form turns all flags on except verbose, while the --none form turns all
flags off.
The current flag names are:
tunnel
tunnelling code
tunnel-xmit
tunnelling transmit only code
pfkey
userspace communication code
xform
transform selection and manipulation code
eroute
eroute table manipulation code
spi
SA table manipulation code
radij
radij tree manipulation code
esp
encryptions transforms code
ah
authentication transforms code rcv receive code
ipcomp
ip compression transforms code
verbose
give even more information, BEWARE: a)this will print authentication and encryption keys in the logs b)this will probably trample the
4k kernel printk buffer giving inaccurate output
All Klips debug output appears as kernel.info messages to syslogd(8). Most systems are set up to log these messages to /var/log/messages.
Beware that klipsdebug --all produces a lot of output and the log file will grow quickly.
The file format for /proc/net/ipsec_klipsdebug is discussed in ipsec_klipsdebug(5).
EXAMPLES
klipsdebug --all
turns on all KLIPS debugging except verbose.
klipsdebug --clear tunnel
turns off only the tunnel debugging messages.
FILES
/proc/net/ipsec_klipsdebug, /usr/local/bin/ipsec

BUGS
It really ought to be possible to set or unset selective combinations of flags.
