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? BTW: I also

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

I have multiple VM's on the same KVM host. One of the VM's is running NTP. All VM's can reach eachother, no firewall in between. But the problem is, the VM's cannot communicate over port 123/udp to the NTP VM. Network: 172.24.100.0/22 KVM: 172.24.101.50 VM ntp: 172.24.102.10 VM foo: 172.24.102.20 1. On the NTP server, listen for any incoming packets from VM foo

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,
