Oracle Linux 5.11 cannot access network
by pavel.v.abramov from LinuxQuestions.org on (#6FKGH)
Hi,
Iim experiencing an issue with configuring network on Oracle Linux 5.11
The system is pingable during reboot for a short time, then itis neither pinging the hosts in the same subnet no receiving pings.
The config is pretty basic i one interface eth0, connected to virtual Hyper-V switch. VLAN is specified in the adapter properties of the VM. (Other VMs on the same subnet connected to the same switch are pingable and accessible)
This is the if-cfg-eth0 content and route-n, ip neighbor outputi

[root@ALNDELX003 i]# I
Still, when I try to ping a neighbor host in the same subnet: iDestination Host Unreachablei, while pinging this Linux server from outside: iRequest timed outi
It doesnit make sense if arp fails to resolve ip into mac (as it looks like), but firewall, ip tables, were turned off (or icmp permitting rules were created).
Pretty sure that something very basic is wrong, but still canit get iti
