Linux
Passive FTP
Als passive FTP niet werkt, dan moeten er modules geactiveerd worden. In /etc/modules toevoegen ip_conntrack_ftp en ip_nat_ftp.
Disable periodical fsck check's
The backup disk on jukebox was forcing a periocal fsck. This can be turned off with tune2fs.
tune2fs -c 0 -i 0d /dev/disk/by-id/usb-WD_My_Book_575532553130303331333730-part1
This should stop this message from syslog:
May 11 11:20:23 localhost automount[18777]: >> /dev/disk/by-id/usb-WD_My_Book_575532553130303331333730-part1 has been mounted 35 times without being checked, check forced.
SFTP chroot
We needed a user account to be able to receive files through SFTP. Since our port is opened at 2222 for the outside world. It seems that there is a CHROOT option in OpenSSH server nowadays. This needs to be changed in /etc/ssh/sshd_config:
Subsystem sftp internal-sftp
Match group sftponly
ChrootDirectory /home/%u
X11Forwarding no
AllowTcpForwarding no
ForceCommand internal-sftpThen create a user like this:
adduser --ingroup sftponly --shell /bin/false <username>
Linux trics
Create snoop file of a port:
tcpdump -nvv -s 0 -w snoopport10295.snoop port 10295Check the number of hits per IP, in the Apache access logs:
cat logs/access_log|grep 05/Feb/2007:14|awk '{print $1}'|sort|uniq -cSee what a process is doing:
lsof -p #PIDLast file in a directory:
ls -ltr|tail -n1Partially extract a tarbal:
tar xvfz backup.tar.gz home/www/login.mobilebridges.com --exclude=*.log --exclude=*.xmlUse the t parameter instead of x to test tar.
tar tvfz backup.tar.gz home/www/login.mobilebridges.com --exclude=*.log --exclude=*.xmlFormat your server:
dd if=/dev/zero of=/dev/hda bs=1MThis writes zero's to /dev/hda, so it will erase all data.
Format disk, using fat32:
1. Use fdisk to create the filesystem: fdisk /dev/hda - follow the prompts 2. Format it using mkfs.vfat -F 32 /dev/hda6 3. Add it to fstab
Add user:
adduser --gid 1010 --shell /usr/bin/false --home /home/www/peru charlyThe GID should be the same for dutch and peru users. The home directory is different though.
Delete files older than 5 days:
find /home/www/login.mobilebridges.com/htdocs/Delivery/Error/ -mtime +5 -exec rm {} \;Rename *.11.csv to *.csv:
rename 's/\.11\.csv$/\.csv/' *.csvThe ereg takes care of the rename action... the *.csv after that just selects the files that need to be renamed with this ereg.
Check projectsize Peru on developement:
/home/www/peru# du --max-depth=1 -hCheck if PING's are reaching the server:
tcpdump host 85.146.37.248 and icmp85.146.37.248 is the source address.
See the number of connections to port 80 by ip:
netstat -pan|grep :80|sed 's/:/ /g'|awk '{print $6}'|sort|uniq -c
Rsync on an other port:
rsync -av --rsh='ssh -p2222' source destination
