|0002631||Kali Linux||[All Projects] General Bug||public||2015-09-08 23:54||2020-12-01 10:48|
|Target Version||Fixed in Version||2016.1|
|Summary||0002631: dnsspoof issues|
|Description||dnsspoof no longer working independently or within ettercap (CLi) as a plugin. It used to work fine within Kali v1.x but not in Kali 2.x.|
This is because dnsspoof in Kali 2.x has response times of up to 500ms. So it is impossible to win the race against the real DNS server.
I tried linking dnsspoof against an older libpcap.so.1.3.0 - and the response times became extremly fast again (<=1ms) \o/
So my workaround is LD_PRELOAD=/usr/lib/x86_64-linux-gnu/libpcap.so.1.3.0 dnsspoof ...
Can you try to install http://http.kali.org/pool/main/libp/libpcap/libpcap0.8_1.7.4-2_amd64.deb (or the same package for "i386" if you use a 32 bit system) and see if the issue persists ?
Or better, can you reproduce the issue with kali-rolling ? You can grab a kali-rolling ISO here:
||After download you can use "dpkg -i libpcap0.8_1.7.4-2_amd64.deb" to install the package.|
|I installed libpcap0.8_1.7.4-2_i386, but not working.|
Hmmm ... http://archive.kali.org/kali-daily-images/kali-linux-rolling-amd64.iso:
||raimund, URL should be working now.|
||Unfortunately with the rolling.iso and/or with libpcap0.8_1.7.4-2_amd64.deb the problem still exists.|
A proper fix for dnsspoof might be to call pcap_set_immediate_mode() which will force fallback to the TPACKET_V2 interface which does not delay sending packets like the default TPACKET_V3 interface. I would like to submit this suggestion to the upstream developers but it looks like that the dsniff package is no longer maintained...
In the mean time, I have modified libpcap to use TPACKET_V2 by default. raimund, can you install this package and report back if it fixes the issue?
||Hi! Newbee here and with Kali. I tried your package (i386) en it worked for me. Thanks!|
||Fixed in libpcap 1.7.4-2kali1|
