The keyboard and everything appears to be dead as the three finger salute

I was under the impression that OpenBSD, a derivative of NetBSD, ran on
almost every platform. I have read about the reputation of OpenBSD
security, so naturally chose it over FreeBSD and Slackware (which I am a
lot more familiar with). Is my platform supported ? If not, should I try
FreeBSD 5.3 Release ?
Thanks.

I'm very surprised. I've run openbsd on various platforms and the basic
install works.
I always boot openbsd from a CD. You could try that.

I could not find any ISO images for OpenBSD. I imagine that this is done to
encourage people to buy the software.
At present, I am not certain I will stick to OpenBSD (just finished
installing FreeBSD on the server), so I wish to try it out first. I have
heard that OpenBSD is a lot more secure than FreeBSD, so I do want to try
it out. |

these is when the

different shared

the application
itself should use the shared libgcc.
Therefore, the G++ and GCJ drivers automatically add
-shared-libgcc whenever
you build a shared library or a main executable, because
C++ and Java programs
typically use exceptions, so this is the right thing to do.

So even if I compile libstdc++ statically and forget about exceptions
what about libgcc_s?
I think this is the biggest nightmare for C++ developers. Worse can be
only
100 miles GNOME library chain. May be switch to Tcl and Ruby :)

I do not doubt that, but I have to get the installation program working
first :)
I thought I could install over ftp. The server in question has a DHCP
connection over ethernet. As soon as the OS is installed and I configure
apache and plone, I will move it to a static IP setup with a dedicated
FQDN.
I hope it is easy to change from a DHCP setup to a fixed IP setup.

Re: Any non-GNU compilers? sick of GNU copylefts

Thanks but it doesn't tell me anything new.
It says if you use C++ you must use the C++ related linker. In my case g++
as ld frontend driver. Also you need compatible compiler versions.
Lets say you have a C program compiled with gcc v2.95.x. Can you assume it
will link with other code compiled with gcc or g++ v3.3?
I assume not because I think the ABI was changed between 2.9.x and 3.x.
So how about C code compiled with gcc 3.1 and linked with 3.4?
Likewise what would happen if you used 3.1 and 3.4 of g++ for C++ code?
Yes I have lots of questions (unfortionatly) because some pieces of
information is still missing in my mind.

Thank you for the suggestion. As soon as my library gets it I hope to become

Well, thanks for the hint. I burnt this ISO (from the ftp server at
openbsd.org) and booted off it. Same results as before. install hangs at
precisely the same point.
Someone on the misc mailing list at openbsd.org thinks that it might be due
to the display switching to the serial port mid-boot and advised me to test
this with a serial cable. Or use a snapshot.
If I am to use a snapshot, there are no guarantees that it would be as
secure / stable as the release. So the entire point of using OpenBSD is
lost.
I have never had a boot process conk out on me like this. Especially on a
contemporary i386 platform server from a major vendor (Dell PowerEdge
SC420).
Any other ideas ?
This is a trifle pointless if I cannot even get the darn thing to boot into
an install. |

Can your C and C++ code be divided into components with clear interfaces?
How do you think about to separate the functionality into shared libraries to minimize
compiler dependencies?

The reason 'the connection goes down' might simply be that the backup
assumes that its master and starts to advertise itself to the clients,
and the clients start using it. If the backup then doesn't forward the
client packets, connections stall.
The master will ignore CARP packets with incorrect hash values (after
logging a message), but of course it can't stop a rogue backup from
advertising, attracting clients, and dropping their packets. If you
consider this a problem, consider an ordinary ARP spoof attack, where
the same thing happens.

It is strange that after implemented PF rules to block unauthorized |

connection stall any more even with the third (rogue, unauthorized with
different password) CARP server turned on in the same subnet.
Now two authorized CARP servers communicate with each other with the
following PF rules:
pass in on {$ext_if} from $vrrp2_ext_ip to any keep state
pass in on {$int_if} from $vrrp2_int_ip to any keep state
Other hosts connected to the carp0/1 interfaces for ordinary network
connection.

Yup, this is exactly the original situiation.

If the password hash is incorrent, the receiver will log the error and
immediately drop the incoming CARP packet:
sys/netinet/ip_carp.c carp_proto_input_c(()
/* verify the hash */
if (carp_hmac_verify(sc, ch->carp_counter, ch->carp_md)) {
carpstats.carps_badauth++;
sc->sc_if.if_ierrors++;
CARP_LOG(sc, ("incorrect hash"));
m_freem(m);
return;
}
It does NOT honour the packet to go into backup state or any such
thing prior to the hash check. If you claim that you can affect
the master with CARP packets not carrying a valid hash, you haven't
provided any evidence yet. What you described so far could have a
number of other explanations.

Most likely you can, if the computers are the same architecture.
If the machines are not identical, you may need to adjust for things
like eg different brands of network cards or graphics if you run X, but
a GENERIC kernel will more likely than not Just Work enough at least to

Hey Dave,
My firewall works fine and I really like to use OBSD/PF for this setup.
In regard to your comment about my posting issue, I'm subscribed to
this newsgroup because I believe there is a lot of talent here and I
felt I could get my question answered. I feel my issue is relevant to
FreeBSD as well and if you knew enough about FreeBSD, you would have
picked up on that. So let's just pretend I configured a couple of
FreeBSD machines instead.
