I've read everything I've found on tcpdump-smb, and still can't get it to work right. I downloaded the binary from samba.org, and executed the command like so: (The command belowis directly from the README.smb that comes with tcpdump-3.4a5.tar.gz) ./tcpdump -i eth0 port 139 host 192.168.0.1 tcpdump: parse error How do I use it to get the decoded smb output?

I want to capture all my Asterisk traffic (including RTP) and then analyse it. My plan was to use tcpdump and then analyse with Wireshark. The following works: tcpdump -i eth0 -s 0 -w /tmp/tcpdump.1 But I want to be a bit more selective: tcpdump -C 100 -W 10 -w /tmp/tcpdump -i eth1 -s 0 udp and dst port >= 5060 This doesn't capture the RTP traffic. Could anyone advise what I'm

On my debian woody (kernel 2.4.31) the tcpdump doesn''t work with imq0 devices. If I try to tcpdump imq devices there is no packet seen: [...] rt1:~# tcpdump -n -i imq0 Warning: arptype 65535 not supported by libpcap - falling back to cooked socket tcpdump: WARNING: imq0: no IPv4 address assigned tcpdump: verbose output suppressed, use -v or -vv for full protocol decode listening on

...er, start over and do the following: [ntp ~]# tcpdump -i any host 172.24.102.20 and port 123 -n ## Listen for packets filtering host 172.24.102.20 and port 123 [foo ~]# tcpdump -i any host 172.24.102.10 and port 123 -n ## Listen for packets filtering host 172.24.102.10 and port 123 While both tcpdumps are running, execute the following: [foo ~]# ntpdate 172.24.102.10 Now, on the tcpdump of VM foo, you will see outgoing packets: 19:45:26.644630 IP 172.24.102.20.ntp > 172.24.102.10.ntp: NTPv4, Client, length 48 As you can see, packets are exiting the server, but there is no response....

Hi list! I have a problem where SIP packets sent by Asterisk do not hit the wire, and I don't know what could cause this. I'm running Asterisk 1.8.28_cert5 with full SIP debug. At the same time, I'm doing a tcpdump of the traffic on the network interface. I can see in the SIP debug log that asterisk is sending packets. Most of the time, I can see those packets in the tcpdump,

I''ve got 2.0.7 running on a machine with 1 physical interface and two bridges, like so -- bridge name bridge id STP enabled interfaces xen-br0 8000.0040f4ce392f no eth1 vif5.0 vif9.0 xenbr1 8000.feffffffffff no

Hi! I have a strange problem with shorewall on one of our routers. When i configure a rule like ACCEPT loc:192.x.x.x net tcp 80 this rules will only work if i do a tcpdump -i all port 80 After doing the tcpdump the clientrules works. When i don''t use tcpdump before the connection will be refused. Best regards, Kai.

That would be very handy,

Dear list, About a week ago, right after 5.4-RELEASE was released, I received a mail from Gentoo Linux's security announcement list about a flaw in tcpdump and gzip. Since none of them are operating system related, I assumed a -p1 and -p2 of the 5.4-RELEASE. Instead, we got a patch for the HTT security issue so I wonder, is the FreeBSD version of tcpdump and/or gzip are secured or simply

Hi, I have a FreeBSD 4.8 box connected to the net which until recently hasn't had any problems. Today DNS lookups mysteriously stopped working (the box has tinydns & dnscache installed to handle dns requests). I noticed some strange things while checking the problem with tcpdump. Tcpdump appears not to show any traffic whatsoever on either my external interface or internal lan interface,
