• Suddenly blocked from a site

  - by Diego Romero

  Suddenly from a time to now I haven't been able to go to a site I used to go frequently for maintenance (Wordpress). I tried different browsers, restarting my laptop, clearing cache, history, cookies. Also did a ping to the site ip, go 4 packets send and 4 lost. This is a problem I think with only my laptop, since I've been able to go into the site…

• Are there any disadvantages of having a "free fall sensor" on a hard disk drive?

  - by therobyouknow

  This is a general question that came out of a specific comparison between the Western Digital Scorpio WD3200BEKT and Western Digital Scorpio WD3200BJKT (which is the same as the former but with a free fall sensor.) Note: I'm not asking for a review or appraisal of these specific drives, as the general question does apply on other brands as well.…

• Does a bad Internet connection increase bandwidth usage?

  - by Synetech

  My (Rogers) cable connection has been pretty bad recently (channels 3 and 10 are particularly fuzzy—it’s analog, not digital cable). Not surprisingly, this has caused my cable modem to drop out and have to reestablish a connection a couple of times since it started. The poor connection of course means higher corruption (not necessarily dropped…

• LVM vs RAID0 vs RAID "linear" - Combine 2 disks as one, data recovery?

  - by leto

  Hi there, given two 2TB USB external disks that have to be combined to one 4TB volume and formatted with one big Filesystem (XFS), I have a small question to ask. Does LVM provide better Data recovery, should one disk be unplugged/damaged by being able to recover the data of the still working disk or is everything lost? I would appreciate a…

• Configure server on network to analyze traffic

  - by Strajan Sebastian

  I have the following network: http://i.stack.imgur.com/rapkH.jpg I want to send all the traffic from the devices that connect to the 192.168.0.1 router to the 192.168.10.1 router(and eventually to the Internet), by passing through the server and an additional router. Almost 2 days have passed and I can't figure what is wrong. While…

• Entire folders deleted from My Documents periodically with remote logins

  - by darron

  I've got a customer who thinks our application is constantly deleting all it's data. It's really becoming a major problem for them. The problem is, there's no way it's us. They are losing not only our entire data folder (which we locate in the user's "My Documents" folder to make it easy to find), but some local settings files which…

• [C++] Adding a string or char array to a byte vector

  - by xeross

  I'm currently working on a class to create and read out packets send through the network, so far I have it working with 16bit and 8bit integers (Well unsigned but still). Now the problem is I've tried numerous ways of copying it over but somehow the _buffer got mangled, it segfaulted, or the result was wrong. I'd appreciate…

• Benefits of "Don't Fragment" on TCP Packets?

  - by taspeotis

  One of our customers is having trouble submitting data from our application (on their PC) to a server (different geographical location). When sending packets under 1100 bytes everything works fine, but above this we see TCP retransmitting the packet every few seconds and getting no response. The packets we are using for…

• Modify an MP3 slightly to change the data appearence

  I'm thinking about encrypting MP3s in a database, so that when user is downloading them with his software desktop player, only the software can decrypt them. This part is not a problem. The problem is I don't want a user to upload an mp3 to the database, then check which changes have been made to the file so he can…

• Is there a maximum delay an UDP packet can have?

  - by Jens Nolte

  I am currently implementing a real-time network protocol for a multiplayer game using UDP. I am not having any technical difficulties, but as I always have to care about late UDP packets I am wondering just how late they can arrive. I have researched the topic and have not found any mention of it, so I assume…

• can I read exactly one UDP packet off a socket?

  - by Brian Palmer

  Using UNIX socket APIs on Linux, is there any way to guarantee that I read one UDP packet, and only one UDP packet? I'm currently reading packets off a non-blocking socket using recvmsg, with a buffer size a little larger than the MTU of our internal network. This should ensure that I can always receive the…

• Usefulness of packets in wireshark? SSDP protocol, rather than HTTP?

  - by Chris

  I used to be able to filter my wireshark packets to get useful information from them. However, with my current configuration on OSX, all of the HTTP traffic is coming through as the SSDP protocol and is generally being unhelpful. Why is this? Actually, it seems that packets on my own system that should…

• Using tshark to generate traffic logs every X seconds

  - by Sridhar Iyer

  I'm trying to use tshark to maintain a running history of all the packets that are going through an interface, for say 30 seconds. I want it to be human readable. This is a linux machine, and without mucking too much into the netstack source (which I can do if push comes to shove), I was wondering if I…
