9.4k 10 38 142. 2 Answers: 3. The nature of RTP transport over UDP is inherently unreliable. Unreliable for delivery and order. So, wrong sequence numbers are to be expected at the receiver side. For media playout the RTP packets have to be placed in order again in the jitter buffer and the payloads accessed in that order.
accept rate: 0%. 5 Answers: 2. The display filter to show only SYN packets is: tcp.flags.syn==1 && tcp.flags.ack==0. If you only want to capture TCP/SYN packets, the capture filter would be: tcp[0xd]&18=2. When you are not only interested in the SYN packets, but also the SYN/ACK packets this changes to:
Wireshark RTP analysis has no notion of profiles for the various transports. It basically only understands the transport of continues voice (G.711) and a bit of Comfort Noise and DTMF signalling. Since other profiles make use of similar methods they come out fairly well in these analysis, but certain details may cause problems, like you've seen.
I can't see (in this entry) content of the print job, version of IPP is 90.100, Operation-id: Unknown (0x656c) and Request ID: 1869894446. I have in Wireshark more then 20 entries like this (IPP request [Malformed Packet] entries with these wrong values).
accept rate: 0%. 3 Answers: 1. You can find wrong subnetmasks either by finding for ARP requests that are looking for MAC addresses of IP addresses they should not be able to reach directly (which is your case), or by finding ICMP redirect messages from default gateways that tell clients to talk to the target node directly (if the mask is too ...
The problem occurs after 30days when the password is due for renewal. Some of the pc's seem to have cached the login details thus giving the wrong passord after the 30days. Three tries of the wrong password and it's a lockout resulting in multiple phone calls to our LEA!!
The WireShark capture is attached. link: static-good-syn.pcap. When the system comes up in DHCP mode, the DHCP exchange works fine but then I cannot connect to the system from my Linux workstation. I send the SYN fine and the system responds with the SYN+ACK but the workstation just keeps resending the SYN. link: dhcp-bad-syn.pcap.
One Answer: 0. It means that wireshark detected that there was something in the data that it coulnd not make sense off. This either means there was something wrong in the received data or the T.38 dissector is not able to read the T.38 packet correctly (either because something was not implemented yet or correctly).
Some thing wrong when I was send a file with FTP . I captured the network card stream ,and found packet was Tagged retransmission by wireshark. client IP:123.160.53.111 sever IP:172.16.8.61was the server SIP and 221.181.100.222 was VIP. I saw that the packet whichTCP sequence number is 70529 retransmissed in the ftp client.
One Answer: 2. which only appeared when application data length exceed MSS. It is a misunderstanding. [TCP segment of a reassembled PDU] is shown in the Info column whenever the TCP packet in question contains just a part of the application layer PDU, except the final one, regardless the MSS. The sending side may not make use of the MSS and ...
