- (djm) Merge OpenBSD changes:
- markus@cvs.openbsd.org 2000/11/06 16:04:56
[channels.c channels.h clientloop.c nchan.c serverloop.c]
[session.c ssh.c]
agent forwarding and -R for ssh2, based on work from
jhuuskon@messi.uku.fi
- markus@cvs.openbsd.org 2000/11/06 16:13:27
[ssh.c sshconnect.c sshd.c]
do not disabled rhosts(rsa) if server port > 1024; from
pekkas@netcore.fi
- markus@cvs.openbsd.org 2000/11/06 16:16:35
[sshconnect.c]
downgrade client to 1.3 if server is 1.4; help from mdb@juniper.net
- markus@cvs.openbsd.org 2000/11/09 18:04:40
[auth1.c]
typo; from mouring@pconline.com
- markus@cvs.openbsd.org 2000/11/12 12:03:28
[ssh-agent.c]
off-by-one when removing a key from the agent
- markus@cvs.openbsd.org 2000/11/12 12:50:39
[auth-rh-rsa.c auth2.c authfd.c authfd.h]
[authfile.c hostfile.c kex.c kex.h key.c key.h myproposal.h]
[readconf.c readconf.h rsa.c rsa.h servconf.c servconf.h ssh-add.c]
[ssh-agent.c ssh-keygen.1 ssh-keygen.c ssh.1 ssh.c ssh_config]
[sshconnect1.c sshconnect2.c sshd.8 sshd.c sshd_config ssh-dss.c]
[ssh-dss.h ssh-rsa.c ssh-rsa.h dsa.c dsa.h]
add support for RSA to SSH2. please test.
there are now 3 types of keys: RSA1 is used by ssh-1 only,
RSA and DSA are used by SSH2.
you can use 'ssh-keygen -t rsa -f ssh2_rsa_file' to generate RSA
keys for SSH2 and use the RSA keys for hostkeys or for user keys.
SSH2 RSA or DSA keys are added to .ssh/authorised_keys2 as before.
- (djm) Fix up Makefile and Redhat init script to create RSA host keys
- (djm) Change to interim version
