  • Conference networking for the socially awkward

    - by Melanie Townsend
    Do you approach a room full of strangers with excitement at all the new people you’re going to chat to over coffee and a muffin as you swap tales of how you convinced your manager to give you the day “off”? Or, do you find rooms full of strangers intimidating and begin by scouting out a place you can stand quietly and not be in someone’s way until the next session begins? If you’re on the train to extrovert city, that’s great, well done, move along. If, on the other hand, a room full of strangers who all seem to inexplicably know each other already is more challenge than opportunity, then making those connections with other professionals can be more difficult. So, here’s some advice, some gleaned from other things I’ve read online when trying to overcome my own discomfort in large groups (hopefully minus the infuriating condescension), others are just things I’ve found helpful over the years. Start small Smaller groups are less intimidating, and, now that you’ve taken the plunge to show up, it’s harder to remain inconspicuous. I find it’s easier to speak to new people once the option NOT to has been taken away. You’re there now, smile through the awkward and you’ll be forever grateful when the three people you’ve met and gotten to know here are also at that gigantic conference later on (ideally, introducing you to other people). Smile, or at the very least, stop scowling You probably don’t even know you’re doing it. If your resting face doesn’t come across as manically happy, tinge that with some social anxiety and you become one great ball of unapproachable. Normally, I wouldn’t suggest this as a problem that needs fixing, I have personally honed this face to use while travelling alone all the time. However, if you are indeed hoping to meet some useful people and get the most out of this conference, you may need to remind yourself to smile. Prepare some ice breakers This is going to sound stupid, like “no one does this right?” stupid, but, just, trust me a minute. It’s okay to prepare. You don’t need to write word-for-word questions to ask people and practice them in a mirror – that would be strange. I’m suggesting to just have an arsenal of questions to ask people if you get stuck, what session has been your favorite, which ones are you most looking forward to, have you heard X presenter speak before, what did you think of them? Even just thinking about these things in advance can help, and, as a bonus, while the other person is answering it gives you a moment to tamp down that panic, I mean breathe, I mean get to know them. You’re not alone (in the least creepy way possible) See that person in the corner clutching their phone with a mild deer in the headlights look?  That is potentially your new conference buddy. Starting with something along the lines of: I don’t know about you, the sessions here are great but I find the crowds a little tough to deal with. Mind if I park here for a second? is a decent opener. Just walking around and looking at exhibitors (if applicable) is fine, but it’s a little too easy to wander about and not actually speak to anyone if that’s all you’re doing. If joining a group of people talking is too much to start with, one-on-one can be easier. Have goals Are there people in particular you wanted to speak to? Did you have a personal goal of speaking to at least “x” new people? Are you trying to get a contact in a specific company because you want to work with them on something? Does the business have vague goals as well that you may or may not be judged on later? Making specific goals you can accomplish lets you know whether you’ve actually succeeded in your “networking pursuits” or what you need to work on more for next time. Everyone’s got their own coping technique. Some people are able to remind themselves that “humans are fundamentally social creatures” and somehow that helps them, others drink which is not really something I recommend for professional conferences but to each their own, and some focus on the fact that networking can play a big role in their career path. Just do what works for you, and if there’re any tricks you’ve found helpful over the years, please share em.

  • setting up a WGR614v7 behind a linux box

    - by commodore fancypants
    Here's the setup, I have an openSUSE box with 2 NICs, one goes to my home network router, the other has DHCP running and it attached to a wireless router. I'm trying to get this setup to work before I switch to the linux box as my home network router. My DHCP will offer the wireless router (a WGR614v7) an address, but anything that connects to the wireless router ends up with a APIPA address. I have all the firewalls on the wireless network turned off as well as the wireless router's own DHCP. The linux box isn't offering addresses to anything past the wireless router. Is this a problem with the router or my DHCP setup? For testing purposes, I have both NICs set in the internal zone and I've tried wireless and wired connections to the WGR614v7 both to no avail.

  • Why is my ipad's wireless so flakey?

    - by Mark
    I'm the proud owner of a new IPad here in the UK. All is good, except for the wifi, which is a bit flakey. It connects fine to my Draytek router which is set for WPA/WPA2 and 56g only, displaying full signal strength. Then, after a few minutes, it goes down to minimum strength... And sometimes it goes back up again. A few times, it seems to loose connection completely, and needs to be turned off and on again. I've looked at the Apple support site, and have tried their recommendations (which are not really very relevant), but still nothing. I've tried setting the router to wpa2 only, and setting long-preamble. Right now, I guess I want to know if it's a hardware problem with my device and should be returned, or if it's a problem with all ipads which will be resolved. Guess I could take it back to the Mac genius bar, but I find those guys so incredibly pretentious and, frankly, rather useless, that i'd rather wait until I've exercised other options!

  • Why does not my Windows XP connects to the wireless?

    - by Amitabh
    I have a dell machine with Windows XP. For the past two days its not connecting to the wireless network. I have another machine with Windows 7 and its connects with the same wireless. This started happening since yesterday when I found a Virus (spy-agent.bw.gen!mem) on my machine which I think I managed to remove using Avira.

  • What brand of wireless router would be compatible with many broadband modems and easy to use?

    - by Junior Mayhé
    Good afternoon I'm having too many intermittent problems with my DLINK DIR 400 router: Wireless connection is lost with no reason. Perhaps the current router is incompatible with this Scientific Atlanta cable modem DPC 2100R2. Scientific Atlanta is a Cisco company, but I'm really worried about this combination DLink - Cisco. Could anyone recommend me a good wireless router for Windows Vista / Windows 7? Thank you

  • What networking hardware do I need in this situation (Fairpoint [ISP] "E-DIA" connection)?

    - by Tegeril
    Right away you'd probably want to say, "Well just ask Fairpoint." I've done that, a number of times in as many different ways I can phrase it and just keep hitting a brick wall where they will not commit to giving any useful information and instead recommend contracting an outside firm and spending a pile of money. Anyway... I'm trying to help a family member out with an office connection that is being setup. I've managed to scrape tiny details here and there from our discussions with the ISP (Fairpoint in Maine) about what is going to be done and what is going to be needed. This is the connection that is being setup: http://www.fairpoint.com/enterprise/vantagepoint/e-dia/index.jsp Information I have been given: Via this connection I can get IPs across different C blocks if that were necessary (it is not) Fairpoint is bringing hardware with them that they claim simply does the conversion from whatever line is coming in the building to ethernet, they have referred to this as the "Fairpoint Netvanta" which I know suggests a line of products that I have looked up, but some (most? all?) of those seems to handle all the routing that I saw. Fairpoint says that I need to bring my own router to sit behind their device. They have literally declined to even suggest products that have worked for other clients in the past and fall back on "any business router works, not a home router." That alone makes my head spin. Detail and clarity hit a brick wall from there. At one moment I got them to cough up that the router I provide needs to be able to do VPN tunneling but they typically fall back to "not a home router" and I was even given "just a business router, Cisco or something, it'll be $500-$1000". Now I know that VPN tunneling routers exist well below that price point and since this connection is going to one machine, possibly two only via ethernet, my desire to purchase networking hardware that over-delivers what I need is not very high. They are literally setting all this up, have provided no configuration details for after they finish, and expect me to just plunk a $500+ router behind it and cross my fingers or contract out to a third party company. If there were other options available for the location, I would have dropped them in a second, but there aren't. The device that is connected requires a static IP and I'm honestly a bit hazy on the necessity of an additional router behind their device and generally a bit over my head. I presume that the router needs to be able to serve external static IPs to its clients, but I really don't know what is going to show up when they come to do the install. This was originally going to be run via an ADSL bridge modem with a range of static IPs (which is easy and is currently setup properly) but the location is too far from the telco to get speeds that we really want for upload and this is also a connection that needs high availability. Any suggestions would be greatly appreciated (I see a number of options in the Cisco Small Business line and other competitors that aren't going to break the bank…), especially if you've worked with Fairpoint before! Thanks for reading my wall of text.

  • I have a collection of dead consumer grade routers, should I buy a real one?

    - by Ex Networking Guy
    Am I crazy for considering purchasing a Cisco 2621 for the house? I am familiar enough with IOS to set up a simple gateway router, I don't really need the experience. At this point, I'm a developer so my days of crawling through CO's and under desks are long past me. But I am really sick of crappy consumer grade networking gear. Maybe I have lousy luck and this stack of WRTG54s is just because I have lousy power, or whatever.

  • From a Java programming perspective, what difference does multicast make to a networking program?

    - by pnut butter
    My manager has asked me to assess what changes would be required to add multicast support to a socket-based TCP/IP networking program that is part of a trading system. As far as I can tell, from the perspective of a Java program, it doesn't seem to matter too much whether the program is unicast or multicast. Doesn't the Java networking API make all of this transparent? By this I mean, wouldn't the change be a simple one of simply adding additional destinations for the outgoing connections?

  • Linux networking crash: best steps to find out the cause?

    - by Aron Rotteveel
    One of our Linux (CentOS) servers was unreachable last night. The server was not reachable in any way except for the remote console. After logging in with the remote console, it turned out I could not ping any outside hosts either. A simple service network restart solved the issue, but I am still wondering what could have caused this. My log files seem to indicate no error at all (except for the various daemons that need a network connection and failed after the network failure). Are there any additional steps I can take to find out the cause of this problem? EDIT: this just happened again. The server was completely unresponsive until I issued a networking service restart. Any advise is welcome. Could this be caused by a faulty hardware component? As per Madhatters request, here are some excerpts from the log at the time (the network crashed at 20:13): /var/log/messages: Dec 2 20:01:05 graviton kernel: Firewall: *TCP_IN Blocked* IN=eth0 OUT= MAC=<stripped> SRC=<stripped> DST=<stripped> LEN=40 TOS=0x00 PREC=0x00 TTL=101 ID=256 PROTO=TCP SPT=6000 DPT=3306 WINDOW=16384 RES=0x00 SYN URGP=0 Dec 2 20:01:05 graviton kernel: Firewall: *TCP_IN Blocked* IN=eth0 OUT= MAC=<stripped> SRC=<stripped> DST=<stripped> LEN=40 TOS=0x00 PREC=0x00 TTL=100 ID=256 PROTO=TCP SPT=6000 DPT=3306 WINDOW=16384 RES=0x00 SYN URGP=0 Dec 2 20:01:05 graviton kernel: Firewall: *TCP_IN Blocked* IN=eth0 OUT= MAC=<stripped> SRC=<stripped> DST=<stripped> LEN=40 TOS=0x00 PREC=0x00 TTL=101 ID=256 PROTO=TCP SPT=6000 DPT=3306 WINDOW=16384 RES=0x00 SYN URGP=0 Dec 2 20:13:34 graviton junglediskserver: Connection to gateway failed: xGatewayTransport - Connection to gateway failed.

What I found out is that arp -an returns an incomplete MAC address for my gateway (which is not under my control; the server is in a shared rack): During failure: ? (xx.xx.xx.62) at <incomplete> on eth0 After service network restart: ? (xx.xx.xx.62) at 00:00:0C:9F:F0:30 [ether] on eth0 Is this something I can fix or is it time for me to contact the data centre?

  • Server Side Developer Prerequisites

    - by Jking
    I am new to server side development and am currently learning node.js. What sort of networking information should I be familiar with to allow for a smooth learning curve with server side development. Could anyone provide resources pertaining to the information required to get into server programming? To give you a better idea of my standpoint: I do not know how a server interacts with a database [Q: How does a NoSQL database, or database in general, communicate with a server?] I am unsure of how a web stack works [Q: I have heard of LAMP but do not know how Apache, MySQL, and PHP interact. Hopefully this applies to other stacks as well. How do the components of a stack work together? Also, is a MEAN stack an alternative, or is it completely irrelevant to this] I have trivial knowledge of internet protocol [however extremely inefficient][Q: What resources are beneficial when learning about networking, and how much/what knowledge should I acquire to program on the server side] I am unsure of what I am unsure of concerning networking information necessary to start development Information on how the client-server model works would be greatly appreciated

  • Ubuntu KVM Networking

    - by Guest
    I have two VMs ( linux based VM ) running on a UBUNTU/QEMU KVM. I am looking at a simple networking model, where in the VMs have public address and need to talk to the outside world and the outside world should be able to talk to the VMs as well. I did this Created a bridge with A.B.C.D/16 ( class B address ) eth2 is part of the brige with A.B.C.E /32 host address VM's interface ( through TAP ) has A.B.C.F / 16 address eth2 and VM interface are both part of the bridge. Now however, I am unable to ping these address from the outside world. If i remove eth2 from the bridge, I am able to ping the eth2. Please let me know what is going on. Guest

  • VMWare Player 5.0 Upgrade - Bridged Networking No Longer Works

    - by Syndog
    I've been using VMWare Player 4 on my Windows 7 PC, running my VMs under a bridged networking configuration without any problem. I settled on bridged networking two reasons... I often use VMs to host web applications for test purposes. I never could get NAT to work for me anyway, but no love lost, considering reason #1. Now that I've upgraded to VMWare Player 5, the situation has completely reversed. In other words, bridged networking no longer works at all, and NAT does. Has anyone else come across this? Any ideas on getting bridged networking to work again? This happens with both Windows and Linux guest OSes. VMWare Tools has been fully updated. I've tried the usual vmnetcfg.exe utility fix, to no avail.

  • What could cause a huge packet loss in Ubuntu 9.10, for both wired and wireless?

    - by xzenox
    I was previously using 9.04 fine (and in fact, I am posting this from my old 9.04 live cd). I tested the following install steps in a virtualbox vm prior to following the sames ones to upgrade my laptop: Download/burn ubuntu minimal cd (12mb one) Install ubuntu minimal sudo apt-get update sudo apt-get upgrade sudo apt-get ubuntu-desktop ubuntu-standard In the VM worked fine and I found myself with a working 9.10 ubuntu, network worked fine and I was able to test my backups and DropBox without a hitch (host was 9.04). When I followed the same steps on my laptop, everything worked up to after 9.10 being installed and working. As far as I can tell, everything besides eth0/wireless works. For some reason, I am unable to access the internet. Ping reports that over 99% of packets get lost (over an hour or so of pinging). This means for example that if I try hard enough, I can load a webpage but only at the cost of much patience... This happens both for a wired and wireless connection to my wrt310n (updated with latest firmware). At first I thought that it could be related to the ipv6 issues ppl have been experiencing however even after disabling ipv6 at the kernel level (through grub), I still get the issue. I do not think this is related to DNS issues or the likes since even when I ping my ISP's gateway IP, I have the same amount of packet loss. No DNS resolving should be required there. Access to my router works peachy with no packet loss there. I've tried different MTU values but to no avail. Note that this issue affects every web-enabled application: firefox, ping, synaptic, etc. The same hardware/router combo works with 9.04 but not with 9.10. In fact, when I did: sudo apt-get ubuntu-desktop ubuntu-standard after 9.10 minimal was installed, it downloaded over 400mb of packages without a hitch so my guess is that one of those packages either in ubuntu-desktop or ubuntu-standard is causing havok. Thoughts?

  • What Wireless Router/ADSL Modem to get? N-band a must!!

    - by JJarava
    I'm looking for a Dual-N band Router OR ADSL Gateway and I'd like some recommendations. Situation: I have a 802.11b/g ADSL gateway provided by my telco, but the WIFI signal won't cover all the house (especially the living-room, so my tv-connected Mac Mini has poor to no internet access). So I'm looking to either replace the DSL modem with a N-enabled one, or to add a Router to the mix. I've had a modem+router setup for many years, and I know the advantatges (double NAT, double FW = more security) and issues (more complex to troubleshoot, two possible points of failure), so I'd rather live with a single (ADSL Gateway) device, if possible. Requirements: Dual-N Band (300 Mbs WIFI) 1 GB Ethernet ports ADSL2+ support (if it's a ADSL gateway, which would be desirable) "Best" range and speed possible Nice to have: USB port to share disks/printers on the network Media streaming I've been a long time user of Linksys, so googling around I found the WRT610N (http://www.linksysbycisco.com/US/en/products/WRT610N) for a "Pure Router" perspective, and it's one of those that Linksys styles "N++" (http://www.linksysbycisco.com/US/en/promo/Promotion-Go-Wireless?stepname=Promotion-Step-Go-Wireless-High-Performance) But I haven't been able to find similar "ADSL" gateways. I've found the WAG320N, but there is little to no info in the Linksys site (i.e., i don't know if it's Dual Band, or if it has GB ethernet) Any opinions/recommendations of other products/suggestions are more than welcome.

  • How to set up multiple SSIDs with bandwidth limiting on a single wireless router?

    - by Rahul Narain
    I have an Asus WL-520GU wireless router connected to a cable modem that I use for wireless internet access in my apartment. I would like to set it up so that it provides two SSIDs: one secured and password-protected for my regular use, and a "guest" SSID that's unsecured but throttled to, say, 10% of the available bandwidth. What is the most straightforward way to do this? I've been looking into DD-WRT and Tomato, both of which support my router. DD-WRT supports setting up multiple SSIDs using the GUI, but I don't know if it's possible to limit the bandwidth of each SSID independently; point #12 in this FAQ thread says it's not possible to limit by day or by MAC address, which is discouraging but not conclusive. Tomato allows bandwidth limits in its QoS settings, going by the screenshot here, but multiple SSID support is still experimental and it doesn't look like it will work with the encryption settings or bandwidth limits in the GUI. I'd like to know a good way to do this which gives me the fewest opportunities for screwing up. I'm no stranger to the command line, if that turns out to be what's necessary, but if so, please explain what the commands are doing because I don't have a good mental model of what needs to happen to set this up.

  • Can I share my cable internet connection through my ADSL wireless router?

    - by Roaders
    Hi All Over the xmas period I am at my in-laws. They have Virgin Broadband (cable) and have a basic modem / router that is plugged directly into their computer using an ethernet cable. My wife and I arrived with 5 PCs! (ok, one is a gift and won't be used) 4 of which are laptops so I would like to be able to use their internet connection. At the moment I am working so have plugged the ethernet cable into my work laptop. Rebooting the router meant that my work laptop now has internet. I have my ADSL Netgear router which is wireless. I tried plugging it in between the router and the PC but I didn't seem to be able to share the internet connection wirelessly. The original PC still had internet despite ony being connected to my router but my wireless laptop didn't have a connection. My old cable router had an internet ethernet port on the back that the modem plugged into. My ADSL router doesn't, it has a phone connection socket. Is there a way of doing what I want with the equipment I have? Thanks
