Hi folks, Today I had some really serious problems with my Gentoo router. I could ping it, and all the network connections were in place and functional, but no outside access. I looked into it and found that the syslog was flooded with this:
Mar 22 21:25:55 localhost kernel: nf_conntrack: table full, dropping packet. Mar 22 21:26:00 localhost kernel: printk: 11 messages suppressed. Mar 22 21:26:00 localhost kernel: nf_conntrack: table full, dropping packet. Mar 22 21:26:05 localhost kernel: printk: 16 messages suppressed. These messages spanned a full 20 hours of the log. I understand that conntrack is the connection tracking system that iptables uses. I also understand that its maximum is something on the order of 65000 simultaneous connections. For a simple home network, I think we can agree that I would probably never approach this number of connections with normal use. So my question is this: what could have caused the router's connection tracker to overflow? -- Dan Cowsill http://www.danthehat.net -- gentoo-user@lists.gentoo.org mailing list
