I used the next perl script for changing references from one interface to

  #!/usr/local/bin/perl
  $|=1;
  while (<>) {
    s@http://search.nic.surfnet.nl@http://search-eth.nic.surfnet.nl@;
    s@http://search.surfnet.nl@http://search-eth.nic.surfnet.nl@;
    s@http://cache.nic.surfnet.nl@http://search-eth.nic.surfnet.nl@;
    s@http://cache.surfnet.nl@http://search-eth.nic.surfnet.nl@;
    s@http://192\.87\.4\.10@http://search-eth.nic.surfnet.nl@;
    print;
  }
