################# Mobatake openssh server install ##########

Try un-installing and then installing openssh-server:

sudo apt-get remove openssh-client openssh-server
and then

sudo apt-get install openssh-client openssh-server
This worked for me. If you still can not connect, try
#############################################################

At least for 14.04, apt-file says:

[romano:~] % apt-file search netinet/sctp.h
libsctp-dev: /usr/include/netinet/sctp.h
so to compile any code that 

#includes the file sctp.h you need to install the package libsctp-dev and its dependences via
sudo apt-get install libsctp-dev

If you want to do this at low level (kernel direct syscall access etc.) 
you should probably replicate all the boilerplate code of the library --- 
why would you do that? You don't do that with sys_open() and friend, you use libc to get these nicely wrapped up.
