The only solution in your case seems to be long enough timeout (say several seconds) before printing interface name. - -andrey -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.3 (GNU/Linux) iD8DBQFEo/lVR6LMutpd94wRAn1dAKCJwVwyuH2Uw//Pp8GvI5oDTg/UWwCguCoO XFTtsYHa+pZ+QuvKBgk5dP0=XMql -----END PGP SIGNATURE----- Using Tomcat but need to do more?
