我正在尝试解决一些持久连接问题,并且我经常在使用dig或nslookup时收到以下错误消息.
bash$nslookup > www.google.com ;; Warning: ID mismatch: expected ID 36298,got 0 ;; Warning: ID mismatch: expected ID 36298,got 0 bash$dig www.google.com ;; Warning: ID mismatch: expected ID 34149,got 0 ;; Warning: ID mismatch: expected ID 34149,got 0 ; <<>> DiG 9.8.3-P1 <<>> www.capitalone360.com ;; global options: +cmd ;; connection timed out; no servers could be reached
任何人都可以了解这个错误信息的含义,特别是“得到0”部分?
