Thank you for fast respond. Sorry, I experimented a lot, but posted just part of information.
Explanations: My goal is capture "endless" traffic and save it to pcaps. As it is endless traffic, I want to have multiple pcaps (for example, minutely or hourly saved). Yes you right "$(date +'%Y%m%d_%H%M')" works, however netsniff with it don't create multiple files with -F: sudo netsniff-ng -i ethx -o /destination/"$(date +'%Y%m%d_%H%M')".pcap -s -F 10s ....just one file, or multiple files (with prefix option) but without changing time variable: sudo netsniff-ng -i ethx -o /destination/ -P "$(date +'%Y%m%d_%H%M')"_ -s -F 10s For tcpdump works: tcpdump -i ethx -w /destination/tcpd_'%Y%m%d_%H%M'.pcap -n -G 3600 2016 m. vasaris 18 d., ketvirtadienis 12:58:10 UTC+2, Vadim Kochan rašė: > > Hi, > > On Wed, Feb 17, 2016 at 9:55 AM, <[email protected] <javascript:>> > wrote: > > Hi everyone, > > > > I have a questions about netsniff-ng and maybe you could help me: > > is there any possibility to format output file name by date & time? > > > > I tried, but didn't work: > > > > netsniff-ng -i ethx -o /destination/"$(date +'%Y%m%d_%H%M')".pcap > > > > (I use netsniff-ng 0.5.7) > > > > PS. for tcpdump it works. > > > > Thanks. > > > > Best regards, > > and > > > > -- > > You received this message because you are subscribed to the Google > Groups "netsniff-ng" group. > > To unsubscribe from this group and stop receiving emails from it, send > an email to [email protected] <javascript:>. > > For more options, visit https://groups.google.com/d/optout. > > I just tried it on Debian (in VBox) : > > sudo netsniff-ng/netsniff-ng -i enp0s3 -o /tmp/"$(date > +'%Y%m%d_%H%M')".pcap -n 100 > > And I got the pcap file under /tmp: > > /tmp/20160218_1251.pcap > > May be I did not understand your problem ? > > Regards, > Vadim Kochan > -- You received this message because you are subscribed to the Google Groups "netsniff-ng" group.
