На тестовой виртуалке под vmware esx 5.5u2, гостевая ОС FreeBSD 10.1 x64 Установлен сетевой адаптер vmx3f0. Установлены vmaware tools. Сделано так, что при старте системы правила pf не загружаются, сквид не загружается (для теста).
Загружаю вручную такие правила (взял за основу https://calomel.org/pf_hfsc.html, пока только тест). pfctl -f /etc/pf.conf-test ext_if="vmx3f0" altq on $ext_if bandwidth 90Mb hfsc queue { ack, dns, ssh, web_high, web_low, bulk} queue ack bandwidth 30% priority 8 qlimit 500 hfsc (realtime 20%) queue dns bandwidth 5% priority 7 qlimit 500 hfsc (realtime 5%) queue ssh bandwidth 5% priority 6 qlimit 500 hfsc (realtime 5%) {ssh_login, ssh_bulk} queue ssh_login bandwidth 50% priority 6 qlimit 500 hfsc queue ssh_bulk bandwidth 50% priority 5 qlimit 500 hfsc queue bulk bandwidth 10% priority 5 qlimit 500 hfsc (realtime 10% default) queue web_high bandwidth 25% priority 4 qlimit 500 hfsc (realtime 20%) queue web_low bandwidth 25% priority 3 qlimit 500 hfsc (realtime 20%) pass out on $ext_if inet proto tcp from ($ext_if) to any flags S/SA modulate state queue (ack, bulk) pass out on $ext_if inet proto tcp from ($ext_if) to any port ssh flags S/SA modulate state queue (ssh_login, ssh_bulk) pass on $ext_if inet proto udp from any to any modulate state queue (dns) pass on $ext_if inet proto tcp from any to any port {80,443} tos 0x31 flags S/SA modulate state queue (web_high, ack) pass on $ext_if inet proto tcp from any to any port {80,443} tos 0x32 flags S/SA modulate state queue (web_low, ack) Запускаю сквид - service squid start Все работает ... До первого запроса к прокси. И тут получаю core.
