2003-01-07 Thread Thomas Gebhardt
Hi, as far as I can see, one can get at least 2 out of the following 3 items: * sshd Privilege Separation * /var/log/wtmp not world readable * users get a lastlog message at ssh login Am I right here? One could also enable the sshd UseLogin option to get the login lastlog message, but I'm

howto calculate fingerprints from ssh host keys?

2003-01-03 Thread Thomas Gebhardt
Hi, this might be a stupid question but I did not find a quick answer by a google search or by reading the ssh faq: At the first ssh login the user is presented a fingerprint, e.g. DSA key fingerprint is df:c2:72:01:ee:0d:05:f9:a1:4f:de:56:a7:48:bd:90 I tried to figure out how to gather these

Re: Fwd: RAZOR advisory: Linux util-linux chfn local root vulnerability

Hi, Debian doesn't use chfn friends from util-linux. wouldn't it make sense (in a case like this) to release a DSA, just stating we are not affected by this, since this fact is not obvious? Cheers, Thomas

Re: apache-ssl/woody cannot handle password protected keys?

Hi, One solution which I use is this... I have both my cert.pem and cert.key file in in a directory... I then run the following: openssl x509 -in cert.pem -out /etc/apache/ssl.crt/server.crt openssl rsa -in cert.key -out /etc/apache/ssl.key/server.key chown root:root
