REPOST: IP options
[reposted because original was sent in HTML by mistake]
I'm seeing something similar to bug 1179
(https://bugzilla.mindrot.org/show_bug.cgi?id=1179), even with the
reordered IP options check.
For some reason, getsockopt is returning an IP options of length 2,
value 00 00.
Would Mark Weindling's original patch

patch for openssh-1.2.2p1
Hi,
openssh-1.2.2p1 seems to have 2 problems on ipv6 (and
ipv4 mapped addresses).
1. "BREAKIN ATTEMPT" warnings from ipv4 node
2. X forwarding
The following patche fixes them.
Thanks.

OpenSSH -current fails regression on Solaris 8, sshd dumps core
Hi All.
While working on something I noticed a regression failure on Solaris 8.
It turned out to be present in -cvs and wasn't due to my changes.
One of the tests that fail is basically:
ssh -2 -F $build/regress/ssh_proxy 999.999.999.999 true
The server reports:
sshd[20529]: Disconnecting: Command terminated on signal 11.
The culprit seems to be session.c line 1019 or so:

Keyboard Interactive Attack?
I read an article today about keyboard interactive auth allowing bruteforcing.
I'm afraid I have minimal understanding of what keyboard-interactive really does. What does it do, and should I have my clients set it to off in sshd_config?

remote-remote scp
Hi everyone,
I know scp is kind of the red-headed stepchild of the suite, but I'd like to propose an extension to the syntax for remote-remote passthrough using the "-3" option.
Currently the syntax is essentially
scp -3 [ -P port ] [user@]host1:file [user@]host2:file
This is great, as long as both remotes are on the same port. It causes difficulties if host1 and host2 are not

Limit number of connections per user?
I'm working from modified 5.0p1 codebase.
What I'm looking for is a mechanism to limit the number of simultaneous
connections on a per-user/IP basis.
That is, disallow multiple simultaneous logins/authentication of the
same user from different IP addresses.
e.g.:
fred from 10.1.1.1 - accept
fred from 10.1.1.2 -- reject while fred is still connected from 10.1.1.1
fred from 10.1.1.1 - OK

Hi Iain. I haven't heard of this effort before. Can you give a few more details?
Thanks,

Equivalent ssh_config setting for "ssh -N"
Oops. That's -T. From the man page, it doesn't really look like there's an ssh_config option for -N.

mput/mget misbehavior
A couple of notes about mget/mput in SFTP (5.1p1).
1. They aren't documented in the SFTP man page
2 They misbehave --
"mput a.txt b.txt" copies a.txt to b.txt on the server
"mput *.txt b.txt" copies the first wildcard match to b.txt on
the server
"mput a.txt b.txt c.txt" copies a.txt to b.txt on the server

SCP
I'm using 5.0p1 (Yeah, yeah. I know.). For various reasons, I am unable
to upgrade to the latest and greatest, which probably would solve my
problem.
Here's my question.
When doing an scp from remote to local (e.g.: scp user at host:remote
localfile), is there any way to specify the path to the remote scp? Or
do I have to patch the code to allow it?

Port Knocking?
I haven't been keeping up with the internals, I'm afraid. Does OpenSSH have support for Port Knocking?
I might be interested in looking into that, as a way of reacquainting myself with the current code base.

Make tests on a cross compile?
I may have asked this before ... my memory is bad.
Is it possible to run "make tests" on a cross-compile build?

Keyboard Interactive Attack?
You need to disable ?ChallengeResponse? (aka keyboard-interactive) authentication, not password authentication, to protect against this attack.

AllowUsers not working under certain conditions
Hello,
I've trawled archives looking for changes in the "AllowUsers" option,
manuals, changes log, reported bugs and to my surprise I can't find anything
or anyone that has reported the issues that I am experiencing.
I am using the default installation sshd_config file as supplied by Redhat
and the only options I have changed are:

ibuf_empty delayed efd
I'm seeing something unusual in 5.0p1. Let me start by saying that I'm
on kind of an oddball
system (HP NonStop).
What I'm seeing is that at the end of an scp session, the server gets
stuck in a loop.
First I see a shutdown failure, followed by looping on an "ibuf_empty
delayed efd 9/(0)" condition.
This may have to do with some minor semantic differences in the way the

dynamic allocation in bsd-poll.c?
I'm wondering about the rationale behind the allocation of the fd_set
for the select() call in bsd-poll.c.
Is there a reason we're dynamically allocating the fd_sets using nmemb,
rather than simply putting three fd_set variables on the stack, followed
by FD_ZERO calls?
This seems to make life more difficult, as evidenced by the "goto out"
statement, needed to free the memory.
