Why there is a difference in MaxAuthTries behavior ?
Hi,
I understand MaxAuthTries is a parameter used to restrict the maximum
number of authentication attempts. But I notice a difference in behavior
when run from different client versions.
The MaxAuthTries at the server side is 6. The server side is running
OpenSSH 6.6 version.
When wrong password is given from an opens...

Problems with openssh and pam_abl
I want to use sshd together with pam_abl to reduce
that logfile spamming with ssh attacks.
So the problem is as follows:
Setting maxAuthTries to 0 or any other values smaller than the default
of 6 changes the behaviour of pam_abl.
First, but this also happens with not using maxAuthTries option, is:
if the clientside closes connection after for example one failed
authentication try then the pam module is not being notified, so no

Implement MaxAuthTries, patch against OpenBSD.
Would something like this be accepted for OpenBSD? If so I'll do the man page
for it.

Yes, I know about MaxAuthTries and I used it as a workaround. Still,
I would imagine the remote server knows there's no point refusing the
slient offered keys one after the other, as none will work. Why then
not telling the client there's no point trying, use password instead?

I am extending that email to this community; where there is a larger

Some things that we will like to achieve are as follows:
SSH:
disable root (uncomment 'PermitRootLogin' and change to no)
enable 'strictMode'
modify 'MaxAuthTries'
modify 'ClientAliveInterval'
modify 'ClientAliveCountMax'
Gnome:
disable Gnome user list
Console:
Remove reboot, halt poweroff from /etc/security/console.app

[Spam] Any plans implement MaxAuthTriesLog?
I'll rephrase my question...
When a user gets their password wrong more than MaxAuthTries times why
isn't the message "Too many authentication failures for %.100s" written
to syslog? The user seems to get it (in a dialog in putty) but it
doesn't get logged. The usual "Failed password for..." messages are
logged.

Ordering of key offers with "ssh -i"
...ot;, the key specified in the
"-i" option is only sent to the server *after* trying all other keys in ~/.ssh
? I couldn't find anything about this in the manual, and it seems like
surprising behaviour to me. It can be the cause of unexpected failures in some
cases, if a server has MaxAuthTries set to a value which is less than the
number of keys that the client has available.
I'm using OpenSSH 5.2p1 on Fedora, although I've recompiled without
Fedora-specific patches to eliminate those as the cause.
Example output where I have "key1", "key2" and "key...

Problem with openssh-4.0p1 and tcp wrappers on RH7.2(Scyld)
...ht have had PAM included, but when I add -with-pam
to configure. I get some more warnings at compile and an error of
something like 'Unsupported option' when sshd is restarted and when
I have UsePAM yes in the sshd_config file.
Another issue I have found is that when enableing the
'MaxAuthTries 3' option in sssh_config (as I have seen recommended) and
restart sshd, I get the message 'Bad Configuration option' and sshd will
not start.
I would appreciate any help.
Thanks,

"PermitRootLogin no" should not proceed with root login
Steps to reproduce:
1) PermitRootLogin no in sshd_config
2) login with "root" user from other host
Present behaviour:
1) it asks for password 3 times and only then close the connection.
2) cpu consumption during bruteforce "attacks".
Expected behaviour:
Immediate disconnect/login fail
Workaround is to change ssh port, or ban IP after some login fails, or
limit IP that can

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?

Greetings,
I discovered an issue in the latest version of SSH, where the number of password prompts are doubled. If I specify 1, I get 2, and so on.

Feature request: FAIL_DELAY-support for sshd
Hello!
My Linux-server is every day attacked with brute-force password cracking
attacks. I use openssh-3.9p1 (SuSE Linux 9.2) with standard setup (PAM,
LoginGraceTime 2m, MaxAuthTries 6). Unfortunately, I see cracking
attempts with very short delays (1 second):

SSH scans vs connection ratelimiting
Gang,
For months now, we're all seeing repeated bruteforce attempts on SSH.
I've configured my pf install to ratelimit TCP connections to port 22
and to automatically add IP-addresses that connect too fast to a table
that's filtered:
table <lamers> { }
block quick from <lamers> to any
pass in quick on $ext_if inet proto tcp from any to ($ext_if) port 22
