Hi, +-From: Usha Ladkani <uladk...@in.ibm.com> -- |_Date: Fri, 5 Apr 2013 12:46:04 +0530 ______ |
|I tried connecting to OpenSSH 6.2p1. But the algorithm negotiation failed |as matching HMAC algorithms were not found. I am pasting the log |statements below. hmac-sha2-256 is not supported in OpenSSH 6.2p1. So |possibly it is not supported in OpenSSH 6.0p1 also, with which you have |tested. ... |INFO: kex: server: |hmac-md5-...@openssh.com,hmac-sha1-...@openssh.com,umac-64-...@openssh.com,umac-128-...@openssh.com,hmac-sha2-256-...@openssh.com,hmac-sha2-512-...@openssh.com,hmac-ripemd160-...@openssh.com,hmac-sha1-96-...@openssh.com,hmac-md5-96-...@openssh.com,hmac-md5,hmac-sha1,umac...@openssh.com,umac-...@openssh.com,hmac-ripemd160,hmac-ripemd...@openssh.com,hmac-sha1-96,hmac-md5-96 ... |com.jcraft.jsch.JSchException: Algorithm negotiation fail OpenSSH has supported "hmac-sha2-256" since its 5.9. Refer to http://www.openssh.com/txt/release-5.9 and http://www.openbsd.org/cgi-bin/cvsweb/src/usr.bin/ssh/mac.c.diff?r1=1.15;r2=1.16;f=h I suggest you to check the config of that remote sshd. I guess an admin of that sshd has disabled it, because "hmac-sha2-256-...@openssh.com" is available. Sincerely, -- Atsuhiko Yamanaka JCraft,Inc. 1-14-20 HONCHO AOBA-KU, SENDAI, MIYAGI 980-0014 Japan.
