Hi I upgrade from kernel 2-16 to 2-26. Now I have problems to config the pseuo port (for loopback) I issued the command: /usr/sbin/kissnetd /dev/ptyq1 /dev/ptyq2 I got kissnetd V 1.5 by Frederic RIBLE F1OAT - ATEPRA FPAC/Linux Project Then: /usr/sbin/kissattach /dev/ttyq1 loop1 10.0.0.3 kissattach: Cannot find serial device /dev/ttyq1, no such file or directory. What is the (new) opposite port for ptyq1? Peter PC2A
