Perl CPANでOpenSSHインストールメモ

Net::OpenSSHを入れるまでの手順。

```:Dockerfile
FROM             centos:centos7.4.1708

RUN              yum -y install epel-release freerdp git nkf tmux telnet telnet-server vsftpd ftp tftp-server xinetd xrdp tigervnc-server expect* *expect* cpan *YAML* libyaml-devel iptables-services dovecot cyrus-sasl cyrus-sasl-* gmp-devel
RUN              yum -y groupinstall 'Development tools'
RUN              yum -y install "perl(Math::GMP)"
RUN              yum -y install "perl(File::HomeDir)"

##### Add
RUN              rm -f /root/.cpan/CPAN/MyConfig.pm
ADD              MyConfig.pm /root/.cpan/CPAN/MyConfig.pm
RUN              cat /root/.cpan/CPAN/MyConfig.pm

##### cpan
RUN              cpan install Net::Telnet
RUN              cpan install Expect
RUN              cpan install Net::SSH
RUN              cpan install Net::SSH::Perl
RUN              cpan install Net::OpenSSH
```

一旦、手動で設定して作成したものをコピーした
