This article describes how to configure a Virtual Machine (VM) running on XenServer to behave promiscuously on the network, that is, allow it to see all network traffic on the Physical Network Interface (PIF).
These commands disconnect and reconnect the VIF to the VM, and it returns with promiscuous mode active. Note: Running the unplug command makes the VM VIF offline, and brings down the interface to the VM until you run the vif-plug command.
Recent research is calling conventional wisdom about monogamous women and promiscuous men into question. One recent study, for example, found that women were more aroused by fantasies involving sex with strangers, and a second showed that women favored pornographic images that were novel over those that were familiar.
The term promiscous binder in a Screening context refers to small molecule ligands which display unspecfific effects toward the Target molecule. These binders can show up in screenings as a Hit, while being in fact false-positives. Promiscous binders can be identified by TRIC, based on several observations: First, promiscous binders can induce target Aggregation, which is indicated by the appearance of irregular TRIC-trace and Well-Scan Quality issues at higher ligand concentrations. This can either result from aggregation of the Ligand itself or an induction of target aggregation. Second, over-stoichiometric (unspecific) binding of a promiscuous binder to the target molecule can be identified based on dose response curves which do not reflect a 1:1 stoichiometry. In this case, fitting of the data with the Hill Model yields Hill coefficients > 1.
If not, this may just be a problem with promiscuous sniffing, eitherdue to running on a switched network or a dual-speed hub, or due toproblems with the interface not supporting promiscuous mode; see theresponse to this earlier question.
the form of promiscuous mode that libpcap (the library that programssuch as tcpdump, Wireshark, etc. use to do packet capture) turns on willnot necessarily be shown if you run ifconfig on the interface on aUNIX system;
Also, some drivers for Windows (especially some wireless networkinterface drivers) apparently do not, when running in promiscuous mode,arrange that outgoing packets are delivered to the software thatrequested that the interface run promiscuously; try turning promiscuousmode off.
In order to capture 802.11 traffic other than Unicast traffic to and from the host on which you're running Wireshark, Multicast traffic, and Broadcast traffic, the adapter will have to be put into monitor mode, so that the filter mentioned above is switched off and all packets received are delivered to the host. Promiscuous mode is, in theory, possible on many 802.11 adapters, but often does not work in practice; if you specify promiscuous mode, the attempt to enable promiscuous mode may fail, the adapter might only capture traffic to and from your machine, or the adapter might not capture any packets.
Even in promiscuous mode, an 802.11 adapter will only supply to the host packets of the SSID the adapter has joined, assuming promiscuous mode works at all; even if it "works", it might only supply to the host the same packets that would be seen in non-promiscuous mode. Although it can receive, at the radio level, packets on other SSID's, it will not forward them to the host.
In promiscuous mode the MAC address filter mentioned above is disabled and all packets of the currently joined 802.11 network (with a specific SSID and channel) are captured, just as in traditional Ethernet. However, on a "protected" network, packets from or to other hosts will not be able to be decrypted by the adapter, and will not be captured, so that promiscuous mode works the same as non-promiscuous mode.
In Mac OS X releases prior to 10.4.0 (Panther and earlier), neither monitor mode, nor seeing 802.11 headers when capturing data, nor capturing non-data frames are supported - although promiscuous mode is supported.
You might have some success capturing non-data frames in promiscuous mode with at least some Centrino interfaces. As these interfaces encapsulate the 802.11 header in a fake Ethernet packet in a non-standard fashion, you will need Wireshark 0.10.6 or later in order to have the non-data packets recognized and properly dissected.
Promiscuous mode is a mode for a network interface controller thatcauses it to pass all traffic it receives to the application rather thanpassing only the frames that the controller is specifically programmedto receive. This mode is normally used for packet sniffing as usedto diagnose network connectivity issues by showing an applicationall the data being transferred over the network. (See theWikipedia article on promiscuous mode for more information.)
The network promiscuous APIs are used to enable and disable this mode,and to wait for and receive a network data to arrive. Not all networktechnologies or network device drivers support promiscuous mode.
Can anyone shed light on what exactly is meant by the last statement. I'm working with an IDS server that has many interfaces and when I use tcpdump -i any, it clearly shows traffic not sourced/destined for the IDS server. However there is another service that already puts all the interfaces into promiscuous mode. Do they maybe just mean that if you use -i any that tcpdump won't put the interfaces into PROMISC mode?
Don't put the interface into promiscuous mode. If you have a small network or cluster, seeing all the packets may be interesting. Otherwise, with promiscuous mode enabled, the network could easily overwhelm your computer.
This, frankly, is a mess. Whilst it's relatively easy to implement via frameworks such as ASP.NET, it leaves you wondering - do cookies really need to be that promiscuous? Do they need to accompany every single request regardless of the origin? No, they don't, which is why if you look in Chrome's dev tools on this very blog at the time of writing, you'll see the following:
Promiscuity is the act of engaging in sexual relationships with numerous people or of being indiscriminate about who you have sexual relationships with. A person who participates in promiscuity is known as promiscuous or behaving promiscuously.
But now scientists have discovered that the tiny bones may actually play a huge role in whale reproduction. Whales belong to a group of sea-dwelling mammals called cetaceans, which also includes dolphins. Comparing hundreds of whale and dolphin pelvic bones to their genitalia and mating style, researchers found that males from more promiscuous species had larger penises and larger pelvic bones. A larger bone would theoretically give a whale more maneuverability while tackling the logistically difficult task of mating in the water, the team writes in a study accepted for publication in the journal Evolution. 350c69d7ab
