Hi dear @sourav295

I dont think i have answer for you question, but can you tell me how you use this cmt tool. I am able to install runc and criu but cmt commands are not working? Thanks

go get github.com/marcosnils/cmt netcom1@cloudlet1:/cmt$ ls bin pkg src test netcom1@cloudlet1:/cmt/src/github.com/marcosnils/cmt$ ls cmd cmt.go iptables LICENSE magic_migrator.sh migrate README.md validate

netcom1@cloudlet1:~/cmt/src/github.com/marcosnils/cmt$ cmt --help No command 'cmt' found, but there are 18 similar ones cmt: command not found

Hello, I have the same issue here. Does anyone know how to solve this problem? in my situation, both machines can ssh with each other. I don't know what exactly this error from.

[updated] I found a way to fix this problem is that you can go into the cmd folder and edit the ssh.go file. Like this: func NewSSH(user, host string) *SSHCmd { c := SSHCmd{} c.config.User = user chunks := strings.Split(host, ":") c.host = chunks[0] c.config.HostKeyCallback=ssh.InsecureIgnoreHostKey() return &c }. add this c.config.HostKeyCallback=ssh.InsecureIgnoreHostKey() line in the NewSSh function. Then, recompile the whole project with the command go build -o cmt cmt.go then fix it.
