I have a problem with network adapter (I think), look I trying to ping my self and got a error sometimes, how this can be? First time in my life I see this.# ping 127.0.0.1PING 127.0.0.1 (127.0.0.1) 56(84) bytes of data.64 bytes from 127.0.0.1: icmp_seq=32 ttl=64 time=0.019 ms64 bytes from 127.0.0.1: icmp_seq=33 ttl=64 time=0.017 ms64 bytes from 127.0.0.1: icmp_seq=34 ttl=64 time=0.023 ms64 bytes from 127.0.0.1: icmp_seq=35 ttl=64 time=0.019 ms64 bytes from 127.0.0.1: icmp_seq=36 ttl=64 time=0.020 ms64 bytes from 127.0.0.1: icmp_seq=37 ttl=64 time=0.017 ms64 bytes from 127.0.0.1: icmp_seq=38 ttl=64 time=0.019 ms64 bytes from 127.0.0.1: icmp_seq=39 ttl=64 time=0.021 ms64 bytes from 127.0.0.1: icmp_seq=40 ttl=64 time=0.021 ms64 bytes from 127.0.0.1: icmp_seq=41 ttl=64 time=0.023 msping: sendmsg: Operation not permitted64 bytes from 127.0.0.1: icmp_seq=43 ttl=64 time=0.021 msping: sendmsg: Operation not permittedping: sendmsg: Operation not permittedping: sendmsg: Operation not permitted64 bytes from 127.0.0.1: icmp_seq=47 ttl=64 time=0.022 msping: sendmsg: Operation not permittedping: sendmsg: Operation not permittedping: sendmsg: Operation not permittedping: sendmsg: Operation not permittedping: sendmsg: Operation not permittedping: sendmsg: Operation not permitted--- 127.0.0.1 ping statistics ---213 packets transmitted, 118 received, 44% packet loss, time 212114msrtt min/avg/max/mdev = 0.017/0.021/0.029/0.005 msYou have mail in /var/mail/rootI have no iptables rules, server worked fine last months# iptables -LChain INPUT (policy ACCEPT)target     prot opt source               destinationChain FORWARD (policy ACCEPT)target     prot opt source               destinationChain OUTPUT (policy ACCEPT)target     prot opt source               destinationif I have a luck and a connection established by ssh with server, this connection will be live and working fine, but after some minutes server stops accepting new connections and stops sending data to new ips.
