    server is not reachable


    Hi at all. I've got a VPS that has Centos 7 64 bit like OS
    Few days ago, after a reboot, server has been unreachable then when i ping it from my computer it give me the error

    Pinging x.x.2.123 with 32 bytes of data:
    Reply from x.x.2.123: Destination host unreachable.
    Reply from x.x.2.123: Destination host unreachable.
    Reply from x.x.2.123: Destination host unreachable.

    then i've ask to my host what could i do and they said me to enter in rescue mode and to read the operative system's logs. Then i've read more logs but, because this is the first time that i find this problem, i don't know neither what logs are important in this case neither what logs'said means and this is why i need your help

    Sorry for my bad english but im italian. Can you help me please? I re-need my server for scholastic and private use :(

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.

    How does the VPS get its IP address? Is is DHCP, or does it have a static address? If DHCP, then the address will likely change on reboot. If that is the case, then you need to assign a static address to it so the address won't change between reboots.
    Sometimes, real fast is almost as good as real time.
    Just remember, Semper Gumbi - always be flexible!

    How long after rebooting do you try to ping it? Also, is the system fully up and running by then?

    Firewall?
    ARP table?
    Check services via Layer 7 (e.g. telnet IP port)?
    Tcpdump /snoop on the network path?

    Are you sure that you have network in the rescue mode?

    From CentOS instalation guide: 26.2. Booting into Rescue Mode

    "If you select a rescue image that does not require a network connection, you are asked whether or not you want to establish a network connection. A network connection is useful if you need to backup files to a different computer or install some RPM packages from a shared network location, for example. "
