After having fresh install of selks 7 desktop and no-desktop, executing selks-first-time-setup_stamus command resulting command not found. In desktop version there's no FirstTimeSetup app, only the .txt file. Please help. Thanks.

Without -L appears an error:

When I try to run /opt/selks/Scripts/Setup/selks-first-time-setup_stamus.sh on an already set up SELKS5 - there is very long hang on the Moloch init par tof the script. But if I execute the scripts in /opt/selks/Scripts/Setup/selks-first-time-setup_stamus.sh one by one - it works fine no issue.

@Jeroen0494 - have you experienced something similar ?

Hi,

It is recommended to maximize the buffers for both rx and tx to prevent packet drops. The script currently only sets a fixed buffer size of 4096 for rx. Line 26 should look like this:
/sbin/ethtool -G $IFACE rx 4096 tx 4096 >/dev/null 2>&1 ;

See here (network card config): https://github.com/aol/moloch/wiki/FAQ#why-am-i-dropping-packets

It would be even better to probe the network card compatibility and dynamically alter the buffer size accordingly (a bit ugly but it works):

RXBUFSIZE=$(ethtool -g $IFACE | grep -m1 RX: | grep -o '[[:digit:]]')
TXBUFSIZE=$(ethtool -g $IFACE | grep -m1 TX: | grep -o '[[:digit:]]')
/sbin/ethtool -G $IFACE rx $RXBUFSIZE tx $TXBUFSIZE >/dev/null 2>&1 ;

Cheers,
