Hello There,

Lately I have been getting "400 Sorry, no more free nodes. Try again later" rather frequently from BBBS. I currently run the 22 node version of BBBS. I am thinking I am just getting spambot'ed. Although, (It may not be related) I did
perform a recent BBBS upgrade. Short of restarting BBBS, is there a way to clear the nodes (I.E delete node busy files) without the necessity to restart BBBS?

I am using iptables to manage inbound connections and have for some time now. The free nodes issue has just been a recent occurrence I.E., the last couple three weeks. In checking I don't see a sudden increase in IP activity.

I have had four new BBS users create accounts in the last week. Something I am always happy to see. :-)

Hi Jeff,

Is it from someone like Yandex that fills up your nodes? That started happening here.. so I use this line to keep them off the bbs nodes:

iptables -A OUTPUT -p tcp -m string --string "block-me.com" --algo kmp -j REJECT

That is all one line, and of course you change "block-me.com" to the name of the site that is nailing your system... works well here. It returns "port unreachable" to the bot... You should see the site name somewhere in your main/inet.log ... that's how I found yandex.

New users is always very neat :)

Hello Janis,

That is all one line, and of course you change "block-me.com" to the name of the site that is nailing your system... works well here.

Here a domain name doesn't show up, just an IPv4 address. I have started to add the IP's to block them. I was looking for a way to limit x connection attempts from the same IP address within x seconds. And decided to use the command line:

iptables -A INPUT -p tcp --dport 23 -i eth0 -m state --state NEW -m recent --update --seconds 10 --hitcount 3 -j DROP

Which has seemed to help as my busy nodes issue isn't as bad as it was. At least BBBS looks to be freeing up the nodes quicker.

Hi Jeff,

Here a domain name doesn't show up, just an IPv4 address.

What does your system show when you type 'host <ipaddress>'? For instance, over
here I see this with the host command:

~host 213.180.204.62
62.204.180.213.in-addr.arpa domain name pointer yandex.com.

I have started to
add the IP's to block them. I was looking for a way to limit x connection attempts from the same IP address within x seconds. And decided to use the command line:

iptables -A INPUT -p tcp --dport 23 -i eth0 -m state --state NEW -m recent --update --seconds 10 --hitcount 3 -j DROP

Yes, I use that line as well. It obviously wasn't enought though yesterday. :(

I use that line above, and also this one (again, all on one line):

iptables -A OUTPUT -p tcp -m string --string "yandex.com" --algo kmp -j REJECT

Three times yesterday, one of my users tried to upload his replies and was unable to.. As I said that's when I went digging for a way to restart bbbs.

Take care,
