Package: openssh-client Version: 1:5.8p1-4 Severity: normal While openssh-client seems to properly switch between the lowdelay/throughput QoS classes depending on whether the session is interactive or not, the new IPQoS option seems to have absolutely no effect: % ssh -vvvo 'IPQoS ef' -4 -Snone vera 2>&1 >/dev/null | egrep tos || echo no match debug3: packet_set_tos: set IP_TOS 0x10 ^D % ssh -vvvo 'IPQoS ef' -4 -Snone vera true 2>&1 >/dev/null | egrep tos || echo no match debug3: packet_set_tos: set IP_TOS 0x08 In both cases, the TOS value should be 0x2e (class ef). Using the hex number does not work either: % ssh -vvvo 'IPQoS 0x2e' -4 -Snone vera 2>&1 >/dev/null | egrep tos || echo no match debug3: packet_set_tos: set IP_TOS 0x10 ^D % ssh -vvvo 'IPQoS 0x2e' -4 -Snone vera true 2>&1 >/dev/null | egrep tos || echo no match debug3: packet_set_tos: set IP_TOS 0x08 I have also verified the actual packets emitted using tcpdump on the next hop. Exactly the same behaviour can be observed with IPv6 after upgrading to 1:5.9p1-7 (see #643312). -- System Information: Debian Release: wheezy/sid APT prefers unstable APT policy: (500, 'unstable'), (1, 'experimental') Architecture: amd64 (x86_64) Kernel: Linux 3.1.0-1-amd64 (SMP w/8 CPU cores) Locale: LANG=en_NZ, LC_CTYPE=en_NZ.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages openssh-client depends on: ii adduser 3.113 ii debconf [debconf-2.0] 1.5.41 ii dpkg 1.16.1.1 ii libc6 2.13-21 ii libedit2 2.11-20080614-3 ii libgssapi-krb5-2 1.9.1+dfsg-3 ii libselinux1 2.1.0-4 ii libssl1.0.0 1.0.0e-2.1 ii passwd 1:4.1.4.2+svn3283-3 ii zlib1g 1:1.2.3.4.dfsg-3 Versions of packages openssh-client recommends: ii openssh-blacklist 0.4.1 ii openssh-blacklist-extra <none> ii xauth 1:1.0.6-1 Versions of packages openssh-client suggests: ii gtk-led-askpass [ssh-askpass] 0.11-1 ii keychain <none> ii libpam-ssh <none> ii monkeysphere 0.35-2 -- Configuration Files: /etc/ssh/ssh_config changed [not included] -- no debconf information -- .''`. martin f. krafft <madduck@d.o> Related projects: : :' : proud Debian developer http://debiansystem.info `. `'` http://people.debian.org/~madduck http://vcs-pkg.org `- Debian - when you have better things to do than fixing systems
