$Id: README.linux,v 1.4 2000/02/01 21:21:47 guy Exp $ The standard libpcap compiled for Linux has a timeout problem; it doesn't support the timeout argument to "pcap_open_live()". The current version of Ethereal attempts to work around this, so its GUI shouldn't freeze when capturing on a not-so-busy network. If its GUI does freeze when that happens, please send a note about this, indicating which version of which distribution of Linux you're using, and which version of libpcap you're using, to ethereal-dev@zing.org. The current version of Ethereal should work with versions of libpcap that have been patched to fix the timeout problem, as well as working with unpatched versions. An additional problem, on Linux, with current versions of libpcap is that capture filters do not work when snooping loopback devices; if you're capturing on a Linux loopback device, do not use a capture filter, as it will probably reject most if not all packets, including the packets it's intended to accept - instead, capture all packets and use a display filter to select the packets you want to see.
