Tectia 5.2 version
Hello everybody. First time I'm dealing with tectia. The problem is I'm not sure where to define key exchange algorithm. I don't want tectia use Diffie-Helman-group1-sha1 KEx. But where to configure it?
This is output from SSH with -vv: debug2: kex_parse_kexinit: diffie-hellman-group-exchange-sha256,diffie-hellman-group-exchange-sha1,diffie-hellman-group14-sha1,diffie-hellman-group1-sha1 debug2: kex_parse_kexinit: ssh-rsa-cert-v01@openssh.com,ssh-dss...00@openssh.com,ssh-rsa,ssh-dss I would assume because of KEx is not defined, it uses group14-sha1 and group-sha1 by default. How can I remove Diffie-Helman-group1-sha1? Thank you, Regards. PS: [root@]# rpm -qa | grep tectia ssh-tectia-server-5.2.0-364.i386 ssh-tectia-common-5.2.0-364.i386 |

https://www.ssh.com/products/support/ ...and the configuration options are listed in the documentation: https://www.ssh.com/manuals/ Since you're having problems with a particular piece of commercial software, the best thing to do would be to use the support you're paying for, and ask them. The stock SSH that comes with pretty much every distro of Linux is typically updated and secure. Any particular reason you're going with something else? |

Either use the stock SSH and contact Red Hat support for assistance with it, or call Tectia support, and ask them how to modify their product. However, before calling RHEL support, be aware that there is ample documentation on how to specify the key exchange method for openSSH. |
