Hi, I'm a developer of a static analysis tool canalyze. Recently I applied it to Openssh-6.2p1. It seems some reports are real after by manually checking: 1.

Hello All, Im using OpenSSH 4.3p2 and tyring to scan a list of 40 machines in my network with ssh-keyscan utility. I used the following command, ssh-keyscan -t rsa -f hosts.txt The man page says that this utility displays the host keys irrespective of ssh or host is up/down and its working great. But in case if the scan stops at 30th host due to some protocol problems, the utility exits and

...CountMax value after ServerAliveInterval seconds to see if keep_alive_timeouts > ServerAliveCountMax, if so , ssh will close the connection and give the "connection timeout" information, else it will increment the keep_alive_timeouts by 1. After Checking, ssh will jump into the "packet_read_poll_seqnr(u_int32_t *seqnr_p)" function, and there it will reset the keep_alive_timeouts variable to "0" again which actually caused the problem. Can you check if it is a bug with openssh50's code or not?Thanks very much. _________________________________________________________________...

...ignores the hosts if they are not up or sshd is not running when used with -f <file> option. But when it encounters any error while retrieving the host key from the machine which is up and have sshd running,it simply exits. This may happen due to transport layer implementation in packet.c at packet_read_poll_seqnr() which results in exiting. My guess is that as packet.c is utilised by all OpenSSH utilities including ssh-keyscan, we can't make ssh-keyscan to continue with remaining hosts as specified in -f <files> in case of an error. But I also vote for atleast documenting this one. Detailed debu...
