If you have doubts about that then you need to take steps to make sure that it doesn't happen - you could run it under `screen` for example so if you lose your connection then you haven't lost your session, or you could run a script using `nohup scriptname &`. Whichever way you do it you need to know that you are not about to lock yourself out permanently! If you have services running on this machine that are listening on particular ports then you need an INPUT rule for each one. Your rules only allow for port 1234 at the moment - didn't you say you had webmin on port 10000 too? You seem to have added that to the output rules instead. Unless you are making outbound connection attempts to other servers that are running ssh on port 1234 then the output rule you have for that is useless too. |
