My collection of hints, tips and tricks
Mounting USB drives
- Slow USB drive performance?
- Mount with option 'noatime' or 'relatime'
- Mount without option sync (e.g. keep default async)
- Auto mount done by OpenElec:
/dev/sda1 on /var/media/Holyhead type fuseblk (rw,nosuid,nodev,relatime,user_id=0,group_id=0,default_permissions,allow_other,blksize=4096)
Samba server / NAS
- How to install?
- Raspberry Pi: Samba Server installieren (German)
- Low Budget NAS mit einem Raspberry PI (German)
- Slow performance?
- see 'Slow USB drives' above
- use Raspbian, etc without GUI to get as much CPU power for file-transfer as possible (OpenELEC or RaspBMC constantly result in about 10-20% CPU load when idle, use top to check!)
Misc Q&A
- Q: Does Raspberry support WOL?
- A: No: the Ethernet chip is connected via USB ([3])
- Q: The new password is to short.
- A: Try adjusting the PAM settings, see Google search for 'pam password minimum length'
- Q: Hot to configure static IP?
- A: In /etc/network/interfaces:
iface eth0 inet static address 192.168.0.31 netmask 255.255.255.0 gateway 192.168.0.1
Things I want to try
- bfq IO scheduler BFQ to increase throughput
- Samba: try adjusting 'socket options' in (/etc/samba/smb.conf) to increase NAS performance: some websites recommend to disable the 'socket options', some recommend to set:
socket options = TCP_NODELAY IPTOS_LOWDELAY SO_RCVBUF=65536 SO_SNDBUF=65536
