    How to ignore RST flag from Kernel

    Hi,

    I am facing one issue. The issue is nothing but kernel RST flags closed ideal sockets.
    It happened every 5 minutes. Can anybody tell how to ignore the RST flag command from the kernel.?

    Re: How to ignore RST flag from Kernel

    To ignore RST flags in the Linux kernel and prevent closed ideal sockets from being reset, you can adjust the TCP settings using the sysctl command. Specifically, you can set the tcp_retries2 parameter to a higher value to increase the number of retransmissions before a connection is considered failed. Use the following command: vn mod apk

    sudo sysctl -w net.ipv4.tcp_retries2=15

    This will allow for more retries before dropping the connection. You may also consider adjusting the tcp_fin_timeout to a longer duration to help mitigate the issue. To make these changes persistent across reboots, add them to your /etc/sysctl.conf file.
