I also can't right now remember buying QoS from company which didn't by default map PREC 5/CS5 to high-priorioty/low-delay (it's used often by default in phones and conferencing systems). So if you're not going for DSCP 0x0, you should go with 0x28, i.e. CS5, and it would work in vast majority of networks which implement QoS, out of the box. -- ++ytti _______________________________________________ openssh-unix-dev mailing list openssh-unix-dev@xxxxxxxxxxx https://lists.mindrot.org/mailman/listinfo/openssh-unix-dev
