  • Sorry, No more free nodes.

    From Jeff Smith@1:14/6 to All on Fri Oct 18 13:22:47 2019

    Hello everybody!

    I seem to have an ongoing problem. A problem that looks to occur on a daily basis
    of late. BBBS presents me with:

    "400 Sorry, No more free nodes, Try again later."

    I have been using Iptables to try to manage the "Bot" connection attempts and it
    has helped. But lately by the end of the day BBBS here is unreachable. I have started to restart the BBBS PC on a daily basis which has made BBBS available again. But sadly only for the day as by days end BBBS is out of free nodes again.

    This has been a problem for BBBS for awhile now. I have tried several things to try to eliminate or at least reduce the problem. But sadly the issue remains.
    I currently have 22 nodes available to BBBS. and the problem looks to exist regardless of service/port used. As http, Telnet, and BinkP are all effected.

    So.. A couple questions. Is there a way to instruct BBBS to flush/close all open
    connections without restarting the PC? (I know, not a solution)

    Is there a more effective way to manage and eliminate spam/bot connections?

    Hi Jeff,

    So.. A couple questions. Is there a way to instruct BBBS to flush/close all open
    connections without restarting the PC? (I know, not a solution)

    I rarely have to reboot my linux system... I do have to take _bbbsd_ down now and then and restart it.. Have you tried that rather than rebooting?

    Is there a more effective way to manage and eliminate spam/bot connections?

    I check my logs often and when I see a particular obnoxious bot type connection, I use this IPTables line:

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

    Works over here... you would of course replace yandex.com with the nasty bot hitting you :) Hope this helps..

    Take care,
    Janis
