ping 192.30.253.112 PING 192.30.253.112 (192.30.253.112) 56(84) bytes of data. 64 bytes from 192.30.253.112: icmp_req=1 ttl=52 time=121 ms git clone git://github.com/lmsgit/lms.git lms Cloning into 'lms'... fatal: unable to connect to github.com: github.com[0: 192.30.253.112]: errno=Connection refused

git nie pracuje via icmp. raczej: ssh -T git@github.com telnet 192.30.253.112 22 ssh -T -p 443 git@ssh.github.com

spróbuj po prostu: git clone https://github.com/lmsgit/lms.git lms

być moze http_proxy czy https_proxy trzeba ustawic abys mial na tym hoscie internet.
