To change ports SSH ports, first edit as root, the sshd configuration file.
Then edit the line which states 'Port 22' and choose an appropriate port not already used on the system.
Doing this, you must be aware that some ports should NOT be used (0 through 1023) and better avoid those from 1024 through 49151. Pick up one from 49152 through 65535 and you'll be fine for now.
Last, restart SSH :
And then see if SSH is listening on the new port (Port number now needs to be declared).
Port redirection may also be an option (see in your router). I don't know what you're aiming at. Could you be more specific ?
I am trying to determing how long it will take to transfer 384 Gb of data across a 100 Mb full ethernet. If I am correct, I come up with 36 Gb per hour. Surely that is not correct. I assumed 100 megabit per second is 10 megabyte per second, which is 600 megabytes per minute and 36 GB per hour.... (3 Replies)

Data(4) Kernel Interfaces Manual Data(4)NAME
Data - Contains data to be sent to remote systems
SYNOPSIS
/usr/spool/uucp/LocalSystemName/D.SystemNamexxxx###
DESCRIPTION
Data (D.*) files contain the data to be sent to remote systems by the uucp uucico daemon. The full pathname of a data file is a form of
the following: /usr/spool/uucp/SystemName/D.SystemNamexxxx###
where the SystemName directory and the SystemName portion of the file name indicate the name of the remote system. The xxxx### notation is
the hexadecimal sequence number of the Command (C.*) file associated with that data file; for example, D.venus471afd8.
After a set period of time (specified by the uusched daemon), the uucico daemon transfers the data file to the designated system. It
places the original data file in a subdirectory of the uucp spooling directory named /usr/spool/uucp/SystemName, where the SystemName
directory is named for the computer that is transmitting the file, and creates a Temporary (TM.*) file to hold the original data file.
After receiving the entire file, the uucp program takes one of three actions: If the file was sent with the uucp command and there were no
transfer problems, the program immediately renames the TM.* file with the appropriate data filename, such as D.venus471afd8, and sends it
to the specified destination. If the file was sent with the uuto command, the uucp program also renames the temporary data file with the
appropriate D.* filename. It then places the data file in the public directory /usr/spool/uucppublic, where the user receives the data
file and handles it with one of the uupick command options. If there were transfer problems (such as a failed login or an unavailable
device), the temporary data file remains in the spooling subdirectory. The uudemon.cleanu command, a shell script, removes these files
automatically at specified intervals, or they can be removed manually.
FILES
