java.net.UnknownHostException: 192.168.0.34:54323: Name or service not known

There are no available Samebug tips for this exception. Do you have an idea how to solve this issue? A short tip would help users who saw this issue last week.

  • I'm just filing this to document that it's an existing way to cause an UnknownHostException. I may fix it, but wanted to make sure I wasn't misinterpreting. I have a multitude of bridges on my home machine. My "local ip" is attached to a bridge br0, not eth0. in this snapshot, vpn is also active (tun0) The lxcbr0 (10.0.3.1) is unused If I specify -ip 192.168.0.34:54323 to h2o (a typo, I shouldn't have specified port with the ip) then H2O.java has this existing code. Is this because the ip can be a name so it's resolving it? In any case, since it's so easy to typo it, maybe a better error message for the user would help direct him. I at first thought I must have messed up some other code I was playing with, but this was existing. I fatfingered the -ip arg. if (OPT_ARGS.ip != null) { try{ arg = InetAddress.getByName(OPT_ARGS.ip); } catch( UnknownHostException e ) { Log.err(e); H2O.exit(-1); } which causes this, because the UnknownHostException isn't caught (on the bad address) 20:12:13.071 main INFO WATER: Possible IP Address: eth0 (eth0), fe80:0:0:0:d63d:7eff:fe18:db22%2 20:12:13.071 main INFO WATER: Possible IP Address: tun0 (tun0), 172.16.0.229 20:12:13.071 main INFO WATER: Possible IP Address: lxcbr0 (lxcbr0), fe80:0:0:0:e000:36ff:fe8b:17c1%4 20:12:13.071 main INFO WATER: Possible IP Address: lxcbr0 (lxcbr0), 10.0.3.1 20:12:13.071 main INFO WATER: Possible IP Address: br0 (br0), 1234:5678:9abc:def0:0:0:0:2%3 20:12:13.071 main INFO WATER: Possible IP Address: br0 (br0), fe80:0:0:0:d63d:7eff:fe18:db22%3 20:12:13.071 main INFO WATER: Possible IP Address: br0 (br0), 192.168.0.34 20:12:13.071 main INFO WATER: Possible IP Address: lo (lo), 0:0:0:0:0:0:0:1%1 20:12:13.072 main INFO WATER: Possible IP Address: lo (lo), 127.0.0.1 20:12:13.072 main INFO WATER: Possible IP Address: Kevin-Ubuntu3 (Kevin-Ubuntu3), 127.0.1.1 20:12:14.390 main ERRR WATER: + java.net.UnknownHostException: 192.168.0.34:54323: Name or service not known + at java.net.Inet6AddressImpl.lookupAllHostAddr(Native Method) + at java.net.InetAddress$1.lookupAllHostAddr(InetAddress.java:901) + at java.net.InetAddress.getAddressesFromNameService(InetAddress.java:1293) + at java.net.InetAddress.getAllByName0(InetAddress.java:1246) + at java.net.InetAddress.getAllByName(InetAddress.java:1162) + at java.net.InetAddress.getAllByName(InetAddress.java:1098) + at java.net.InetAddress.getByName(InetAddress.java:1048) + at water.H2O.findInetAddressForSelf(H2O.java:354) + at water.H2O.main(H2O.java:913) + at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) + at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) + at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) + at java.lang.reflect.Method.invoke(Method.java:606) + at water.Boot.run(Boot.java:307) + at water.Boot.boot2(Boot.java:283) + at water.Boot.boot(Boot.java:150) + at water.Boot.main(Boot.java:122)
