DNS configuration

Adding the following two sentences before the / etc/resolv.conf file will only add 172.17.205.28 DNS to parse the failed nameserver 127.0.0.1 # required nameserver 172.17.205.28 # required [main local network card].

test

The configuration of this machine, like other machines, must be added before it will take effect, because DNS parsing will parse root@center ~ # ping h2PING H2 (172.17.205.32) 56 (84) bytes of data.64 bytes from 172.17.205.32 (172.17.205.32): icmp_seq=1 ttl=64 time=0.155 ms64 bytes from 172.17.205.32 (172.17.205.32): icmp_seq=2 ttl=64 time=0.203 Ms ^ C-- H2 ping statistics-- 2 packets transmitted, 2 received 0% packet loss, time 1000msrtt min/avg/max/mdev = 0.155 ms, 0.179 ms, 0.203 ms

Add parsing

Click Save, and it will take effect automatically in a few seconds.

Be careful

It is recommended to keep the hostname of other machines the same as above, otherwise the following problems may occur: root@asdf ~ # ping h0ping: H0: Name or service not known
