interesting. i don't know how ssh can work togethor with dns, but other program fail with dns... what OS is auriga? one way to make sure this is only a local dns issue is to use ip addresses in your setting. if it work, you can be sure it's only a local dns issue. and if this is the case, could you share your experiences with us? thanks.
