Hello, Just curious if there is anything like this software for Linux, that will play back not only the video, but show recorded GPS data too? http://www.registratorviewer.com/index_en.html As far as I can tell, maybe not. Or at least Google isn't telling me anything. However just wondering. Thanks

Host denied: sshd from 43.255.189.72(unknown)-43.255.189.72

by Jobst Schmalenbach

Hi This is a strange problem as it is on a machine behind a DMZ and "chained" FIREWALL (CentOS). I have a "/etc/hosts.deny" that has following line: ALL : ALL : spawn ( /usr/sbin/safe_finger -l @%h | /usr/bin/Mail -s "THE_HOSTNAME\: Host denied\: %d from %c(%u)-%h" some(a)domain.com) & which delivers following email every random minutes: THE_HOSTNAME: Host denied: sshd from 43.255.189.72(unknown)-43.255.189.72 Normally it would not bother me, but the fact this machine is behind a DMZ and a FIREWALL makes this "interesting". I, too, know the machine (and network) in question are quite wellknown ;-) Now the thing is that "hosts.deny" sits before I can see the traffic with tcpdump/ngrep/iptraf, so this makes it a little harder to debug. This is what I know: - only I have shell access (passwd file is full of /bin/false and /bin/nologin) and it's ONLY via keys. - rkhunter, chkrootkit and so on have no warnings - the machines sendmail has clamav attached - external firewall disallows access to that machine (only from internal network) - external firewall blocks the entire network of 43.0.0.0/24 - the machine is my Samba Server - the machine is fully up to date and rebooted - it is my webdevelopment server for some domains - it has some internal webserver tasks - I have turned off ALL internal devices that could be hacked (nas drives, wifi, etc) - the messages come up even if NO workstation is on - external ssh is firewalled I have tried all the standard utils (tcpump,lsof,fuser,netstat and so on) but this one has me baffled. Any ideas anyone?
