Hi,
Well in Twisted checked out directly from GitHub, this seems to work:
ssh -vv -oKexAlgorithms=ecdh-sha2-nistp256 -oMACs=hmac-sha2-512
user@localhost
and these fail:
ssh -vv -oKexAlgorithms=diffie-hellman-group1-sha1 -oMACs=hmac-sha2-512
user@localhost
ssh -vv -oKexAlgorithms=diffie-hellman-
hi,
Yes, you are right. ssh -vv -oKexAlgorithms=diffie-hellman-group14-sha1
-oMACs=hmac-sha2-512 user@localhost
against a Twisted ssh server, and i saw the problem. The reason is that
twisted(16.6.0) is not supported the diffie-hellman-group14-sha1 and
ecdh-sha512-nistp512 key exchange a
Hi,
Is this what you are saying:
Twisted Server + OpenSSH client == WORKS
Twisted Server + Xshell client == WORKS
OpenSSH Server + SecureCRT client == WORKS
Twisted Server + SecureCRT client == FAIL
??
I don't have SecureCRT client, so don't know the solution to this problem.

hi:
Oh, I'm sorry, It is my server-side code has bugs with Twisted(16.6.0)
Conch, that i have fixed it . But 'Message Authentication Code did not verify
(packet #3)' error will occurs with the SecureCRT(8.0.0 or 7.3.4) client. If
I connect OpenSSH_5.3p1 (or OpenSSH_6.6.1p1 ) sshd serve
Jianchen,
Can you provide more details about the server you are writing?
I cannot reproduce your problem with the latest Twisted code in trunk.
Here is what I did:
git clone https://github.com/twisted/twisted twisted-test
cd twisted-test
python setup.py develop
cd docs/conch/examples
mkdir ssh
Sorry to have misdiagnosed your problem. I am glad that Adi Roiban could help!
Thank you very much for upgrading to the latest version - it helps us a lot
for users to try recent versions of the software. (And when a fix is
available, of course, you will have to upgrade to get it, so upgradin

Hi Jianchen,
As I said on stack overflow, you will need to upgrade to a more recent version
of Twisted to get a version with that bug fixed. If it's still a problem in a
current version, you'll need to provide more details, ideally a short SSCCE
