from my baseline; sorry it's in Dutch: Bij het compileren van de software verdient het aanbeveling het versienummer en bijbehorende tekst in de file version.h ‘#define SSH_VERSION "OpenSSH_3.0.2p1"’ te veranderen voor een bogus-tekst. Hierdoor kunnen hackers niet meer de gebruikte ssh-versie achterhalen om daar misbruik van te maken. So, change versiontext in string ‘#define SSH_VERSION "OpenSSH_3.0.2p1" in sourcefile version.h to a bogus text you should upgrade your ssh anyhow, so just change the source and then compile ;-) cheers. ----- Original Message ----- From: "Michael Appeldorn" <appeldorn@codixx.de> To: <suse-security@suse.com> Sent: Sunday, February 03, 2002 9:51 AM Subject: [suse-security] How2 getting sshd quiete

Hi list,

if i telnet against a sshd like this

telnet 192.168.1.2 22

i'll get e.g. that:

Trying 192.168.1.2... Connected to 192.168.1.2. Escape character is '^]'.

SSH-2.0-OpenSSH_2.99.99p5 ^^^^^^^^^^^^^^^^^^^^^^^^

How2 suppress this output. Hopefully without any recompile?

echo "1" > \proc\sys\net\SECURITY_THROUGH_OBSCURITY
