Hi, I run my own ftp server with vsftpd with slackware 10.0. Anyways I am currently having problems with users using the syst command to find out which OS I am running. The output of the syst command is:
215 UNIX Type: L8
Can someone please tell me how I can disable the syst command in slackware 10.0? so users who connect to my ftp server cannot use this command?
thanks in advance
Heres a log from my packet sniffer, as you can see someone is really hammering my machine....anyone have any ideas what this person is trying to do exactly:
ok then in that case I won't disable syst if it hurts some ftp clients... but what do you guys think about my log above? I tried blocking the IP in /etc/hosts.deny but he's still hammering me....
thanks for helping me by the way
how can I stop 22.214.171.124 from abusing the server(as you can see in my log above) any ideas?
I've disabled ssh and have a firewall im really interested to know what this "CHECKSUM INCORRECT" means
I guess i'm paranoid this guy is trying to hack me(and I think he is) this is all going on right now as I type this
Yes this is a anonymous only FTP server. I recently had to take all my mp3 files of my FTP due to certain reason's.... actually I did so just today. So thats probably why he's changing to directorys that don't exist. Glad to hear I don't have to worry but at the same time this experience has made me up my firewall policies and my awareness which I guess is a good thing. I guess im just paranoid thanks again ilikejam
