Example 6-7 A DNS traceroute |
The code in the book as below:
res, unans = sr(IP(dst=TARGET, ttl=(1,30)/UDP(sport=RandShort())/DNS(qd=DNSQR(qname="www.test.com"))), timeout=4)
res.make_table(lambda (s,r): (s.dst, s.ttl, r.sprintf("{ICMP:%IP.src%#%ICMP.type%}{UDP:%IP.src% %DNSRR.rname%}"))
and it has two right parenthesis with wrong place.
this should correct as follow:
res, unans = sr(IP(dst=TARGET, ttl=(1,30))/UDP(sport=RandShort())/DNS(qd=DNSQR(qname="www.test.com")), timeout=4)
res.make_table(lambda (s,r): (s.dst, s.ttl, r.sprintf("{ICMP:%IP.src%#%ICMP.type%}{UDP:%IP.src% %DNSRR.rname%}")))
the first stament change the parenthesis after "www.test.com"))) to ttl=(1,30))
the second stament miss one right parenthesis in the end

Figure 13-1 |
On the lower right of the "Packet Flow through netfilter" figure the output blocks should read "mangle
POSTROUTING" and "nat POSTROUTING", not "mangle PREROUTING" and "nat PREROUTING".
The blocks on the lower right are correct however.
