I updated my SSH port from 22 to 6433 and now I can't SSH into my machine. I updated this line in /etc/ssh/sshd_config:



# If you want to change the port on a SELinux system, you have to tell
# SELinux about this change.
# semanage port -a -t ssh_port_t -p tcp #PORTNUMBER
#
Port 22


to



# If you want to change the port on a SELinux system, you have to tell
# SELinux about this change.
# semanage port -a -t ssh_port_t -p tcp #PORTNUMBER
#
Port 6433


I restarted my ssh service using 



$ service sshd restart


no errors were returned. Open up a new Terminal tab and run:



$ ssh user@ip.address -p6433


which returns:




ssh: connect to host ip.address port 6433: No route to host




Not sure how to go about fixing?



update -



SELinux is not enabled






centos ssh

  • You may have selinux turn on and as the comment right above Port line on the text you copied says you may need to update selinux with semanage.

    If the SSH server wasn't listening on that port, you would have gotten Connection refused. Now you're getting No route to host which means that the client can't even see the host on the network.

    Check if iptables/firewall-cmd is configured to allow your new port. If that is not the cause, check if you are accessing the ip address through another network device. In that case the new port must be opened there as well.

Thanks to @Vinod I got on the right track, achieved by doing:



$ firewall-cmd --zone=permanent --add-port=6433/tcp
$ firewall-cmd --reload


now I can SSH into my server.

            How many registers does an x86_64 CPU actually have?

            Image
            Clash Royale CLAN TAG #URR8PPP up vote 2 down vote favorite I am currently learning reverse engineering and am studying the flags register. I had in my mind that rflags was just another name for one of the 16 general purpose registers, for example rax or rbx . But it looks like rflags is actually an additional register. So that makes 17 registers in total... how many more could there be? I have spent at least an hour on this and found numerous different answers. The best answer so far is this, which says that there are 40 registers in total. 16 General Purpose Registers 2 Status Registers 6 Code Segment Registers 16 SSE Registers 8 FPU/MMX Registers But if I add that up, I get 48. Could anybody provide an official answer on how many registers an x86_64 CPU has (e.g. an Intel i7). Additionally, I have seen references to 'hardware' and 'architectural' registers.
