If you want to just what's changed in the log file since the last time you connected, look at the package logtail. For example you might run this command: while :; do nc -l -p 5558 -c "logtail /var/log/syslog"; done This would have nc exit when it's done dumping /var/log/syslog and the next time someone connects it should pick up where it left off.
