1. The network will be upgraded to Constantinople & Petersburg at block height of 7280000. L, Z, b show that it will be upgraded on March 1, 2019 Beijing time. I don't know if the upgrade is successful
2. It should be Linux that adds routing paths< The routing path added by route add - net 10.26.96.0/28
GW 10.62.26.113 must pass through the network card selected by this gateway
dev eth2
GW 10.62.26.113 must pass through the network card selected by this gateway
dev eth2
3. The main idea is:
add a default global routing record. The target network xx.xx.xx.xx (NextHop via xx.xx.xx.xx) is to be reached through the gateway (Ethernet card eth0), and the link weight is 1
add a default global routing record. The target network xx.xx.xx.xx (NextHop via xx.xx.xx.xx) is to be reached through the gateway (Ethernet card eth0), and the link weight is 1
4. The default route should not be added in the way of route-eth0. This should be adding gateway to ifcfg-eth0 file
route-eth0 should be a static route< br />192.168.55.0/24 via 192.168.234.1
route-eth0 should be a static route< br />192.168.55.0/24 via 192.168.234.1
5. IP route add 10.89.255.0/24 via 10.89.255.254 dev eth0
for all packets with destination address of 10.89.255.0/24, the next hop address (Gateway) is 10.89.255.254, which is sent out from the local eth0 interface.

6. 1. Use ifconfig eth0 up command to open the next network card< br />#ifconfig eth0 up
2、 Change eth0 configuration:
#vi / etc / sysconfig / network scripts / ifcfg-eth0 display:
device = eth0
onboot = no / / boot the network card
bootproto = static
IPADDR = 192.168.1.8 / / set your own valid IP address
netmask = 255.255.0 / / subnet mask
gateway = 192.168.1.1 / / valid gateway address
hwaddr = 00:0c: 29:96:38: F8
note the ONB in it OOT = no, change it to yes, and the network card is activated
3. Restart the service
? Service network restart
configuration takes effect after restart.

IPADDR = 192.168.1.8 / / set your own valid IP address

3. Restart the service
? Service network restart
configuration takes effect after restart.
7. You want a network card device, right
/ etc / network / interfaces
sudo VI / etc / network / interfaces
you can edit it and replace the line about eth0 with the following line:
? The primary network interface - use DHCP to find our address
auto eth0
Iface eth0 INET DHCP
use the following command to make the network settings effective:
sudo / etc / in It.d/networking restart
you can also directly enter the following command from the command line to get the address
/ etc / network / interfaces
sudo VI / etc / network / interfaces
you can edit it and replace the line about eth0 with the following line:
? The primary network interface - use DHCP to find our address
auto eth0
Iface eth0 INET DHCP
use the following command to make the network settings effective:
sudo / etc / in It.d/networking restart
you can also directly enter the following command from the command line to get the address
8. If you add a route, as long as the data leading to the IP starting with 61 goes from eth0, the network card will be executed directly in DOS or written as text, and it will be executed directly in bat format, and the restart will be invalid
9. Unknown_Error
10. Because bitcoin is the first digital currency with the longest history, and it can cope with inflation and store value, in general, it meets people's demand for digital currency in many aspects, so it naturally becomes everyone's favorite currency.
