Circuit QNA-0, Adjacent node = 7.80 (BITXT1) The TOPS-20 one is connected to the same virtual bridge and it is running in the same virtual machine, but it runs OK. Any idea? (My suspect is the NI configuration in the KHL ini file...) Jordi Guillaumes i Pons jg at jordi.guillaumes.name HECnet: BITXOV::JGUILLAUMES
