One-liner for adding veto files to samba

for SHARE in $(net conf listshares); do net conf setparm "$SHARE" 'veto files' '/.DS_Store/'; done;

Good to have when you have lots of shares, and lots of Mac users creating .DS_Store files everywhere they go …

Cisco Meraki running in low power mode

Hooked up a bunch of Cisco Meraki MR34 to a HP Procurve zl5412 switch. They kept reporting ”PoE 802.3af (running in low power mode)”. The switch is capable of delivering over 30 watts per port, so PoE+ (802.3at) should’t be a problem.

Solution? Turns out just raising Maximum Watts to 33 don’t cut it. The Meraki starts using all them watts but still reports low power mode. One also has to enable PoE LLDP-MED (can be done via the Procurve switch web interface) to get Meraki running with full power.

(Without the full power the Meraki won't use some of it extra nifty scanning capabilities.)

Disable Quick View/Quick Look for network volumes

Quick View in Mac OS X can cause a lot of trouble on network volumes. Users get ”access denied”, are unable to copy files and so on. Of course you can delete Quick View completely, but another way to do it is to deny access by path:

sudo nano /usr/share/sandbox/quicklook-satellite.sb

and add the following line at the end:

(deny file-read*

     (subpath ”/Volumes/the-name-of-your-network-volume”))

And there you go. No more pesky file locks, at least not caused by quicklook.

Async replication with V7000 Unified

When replication back and forth between to V7000 Unified systems you risk replicating back the replicated data.

Check the file /etc/async_repl/gpfs.filter to see that the replication destination really is excluded. Seems like the gpfs.filter file is overwritten sometimes when upgrading ...

Cleanup /boot in Ubuntu

sudo apt-get remove --purge $(dpkg -l 'linux-*' | sed '/^ii/!d;/'"$(uname -r | sed "s/\(.*\)-\([^0-9]\+\)/\1/")"'/d;s/^[^ ]* [^ ]* \([^ ]*\).*/\1/;/[0-9]/!d')

Good to have when /boot is almost filled up …

Route all traffic via OpenVPN on Iphone

The OpenVPN app on Iphone seems to ignore all extra routes, so when wanting to access other internal networks then the default one, put this in your IOS ovpn config:

redirect-gateway x.x.x.x

Better then doing it server-side and forcing all traffic for all clients via the vpn …

One-liner for removing umlauts

Quick ’n dirty one-liner for removing those pesky umlauts (å, ä, ö, et al) and other utf-8 stuff from your filenames:

find ./ | while read -r FILE; do mv -v "$FILE" "`echo $FILE | iconv -c -f utf-8 -t us-ascii//TRANSLIT`"; done;
