Anonymous FTP Account

January 4, 2006 Posted in FTP

Several months ago, I switched to pure-ftpd from proftpd for my Linux VPS and FreeBSD server, but I didn’t test the anonymous login on Linux, just found it’s enabled by default!! Fortunately, it wasn’t abused. If someone used it for video download, I could face a big bill for bandwidth usage. Very lucky. Read More

Change FTP Port

December 31, 2005 Posted in FTP, Security

After I changed the ssh port, combined with the changes of net.inet.tcp.blackhole and net.inet.udp.blackhole, now the server is completely free of ssh login attempts. I realized these two changes should be made together, it doesn’t make much sense to change only one of them. For example, if only change the port, the server will still respond to the port scan, it very probably gets more scan activity. What if only changed the system varibles? Since the ports of common services are the main target, the evil people still can easily find the ports to attack. Read More

Switch to pure-ftpd

WebHost Manager on my Linux VPS displayed the following message:

At this time, it is recommended that all customers using proftpd Switch to pure-ftpd as soon as possible to eliminate a potential security hole. It is important to consider that this security hole has not been verified. Multiple reports of compromised machines which have Trojans horse binaries installed with the proftpd group have been received. We wish acknowledge that there is only circumstantial evidence pointing to proftpd as the culprit, however we feel it is best to err on the side of caution.
