Nextcloud Owncloud Calling Home

I did a deeper firewall test on my fresh installed OpenWRT Router and activated a „Ads Blacklist“ after this my owncloud Share Login loops! Result: Seems that some IP’s of the „Update Check Tool“ Servers, which is installed inside the PHP-Kit is blacklisted. So it seems the Code calls home!  With this option its possible to count and collect IPs of Setups! Perhaps checkout unpatched Versions! I didn’t check deeper, but the behavior was clear without viewing the codes. After publish this Info via Twitter:   REMARKS: No Company / Developer works for „free“ After Setup of PHP-Kits do a […]

Rsync: Performance NFS Boost

If you use two Linux Servers with NFS Shares connect over Gigabit Interfaces for Backups, you perhaps remark performance problems on using rsync. It does often pause transmissions or reach only a rate of 32Mb/s. That’s bad and waste time and energy. Background: After some Tests of running Backups with single files and compressed big archives, the scans of my tools like iftop, systat, iptraf found out that the used Option „rsync -avz“ was the bottle neck, cause the Data Rate break down at intervals. The „z“ compress option was described on howtos as must have for slower networks did […]
