Hi All, kex_reset_dispatch() function is called in kex_setup() function at the start of the key exchange. But kex_reset_dispatch() is called again in kex_finish(). Why is it needed ?

In sshconnect.c there are two global variables for server_version_string client_version_string. These are used just in a few functions and can easily be passed as parameters. Also, there is a strange construct, where their memory is allocated to the global pointers, then copies of these pointers are assigned to the kex structure. The kex_free finally frees them via cleanup of the kex

Hi, 1. I think you should apply the attached patch to openssh-2.9p1, otherwise ssh-keyscan on linux boxes with glibc-2.1 will experience enormous timeout delays. 2. Is there a program like ssh-keyscan for the Version2 (dsa and rsa) keys?? regards Peter Breitenlohner <peb at mppmu.mpg.de> -------------- next part -------------- diff -ur openssh-2.9p1.orig/ssh-keyscan.c
