conntrack_ftp: partial 227

Today I came across the following message in the kernel's log: conntrack_ftp: partial 227 4048680485+13 Fortunately this link helped:
The FTP conntrack helper has found a partial matching when parsing a request to start a connection in passive mode (ie. needs missing information to track that connection, malformed packets,...). In that case such packet is silently drop[ped].

snippets from da brain

Wanna clone a debian installation real quick? Try:
# dpkg --get-selections \* > ~/dpkg.selections
# dpkg --set-selections < ~/dpkg.selections
# apt-get install dselect-upgrade
Or how about installing Fedora in 3 steps?
# rpm --root /fc7/ --initdb
# rpm --root /fc7/ -ivh --nodeps ftp://ftp-stud.fht-esslingen.de/Mirrors/\
fedora.redhat.com/linux/core/development/ppc/os/Fedora/fedora-release-*.noarch.rpm
# yum --installroot=/fc7/ -y groupinstall Base
(the latter is from Arnd Bergmann in <200703190134.26030.arnd@arndb.de>)

learning sth. new every day

You sure noticed that this is not a diary, more a monthly(?) if at all. But now I decided to move my irregular braindumps to this place, so I and you can find even more (un)interesting stuff. Today: samba! Having used samba since 1.9.18 or so, I thought I've come across every configuration option mentioned in the ever growing smb.conf. Of course I was wrong:
  • With socket address I can finally restrict nmbd to a single IP address, so it does not listen on every freaking interface.
  • Using load printers = no printing = bsd printcap name = /dev/null disable spoolss = yes gets rid of the annoying Unable to open printcap file /etc/printcap messages in the syslog when printing NOT via smb.
  • And finally I found some time to play around with socket options, I guess I'll go with

    socket options = SO_KEEPALIVE TCP_NODELAY IPTOS_LOWDELAY IPTOS_THROUGHPUT SO_SNDBUF=8192 SO_RCVBUF=8192

    for a while and see what it gives.
  • When mount.cifs is missing, cifs.ko might complain: CIFS VFS: cifs_mount failed w/return code = -22. See this irclog why this might be OR use an IP address for the hostname when mounting the share OR just install smbfs and be done with it.
