I have a friend who has become totally reliant on an e-mail account, which was provided by an internet service provider which she has just left to go to a new ISP. She uses Outlook 2003 as her e-mail client program. Unfortunately, she is now finding that after moving to this new ISP that although she can receive e-mails absolutely fine, she cannot send e-mails.

How can I unlock an iphone tied to t-mobile in the UK? I have received as a Christmas present an iphone which is locked to t-mobile. I am currently on an 02 contract that ties me for a further 6 months. Clearly, I would like to use my 02 sim with this iphone, however, when I went to a shop who specialised in phone unlocking, to get it unlocked, I was told that he could not unlock it and that it would take atleast a month to get t-mobile to unlock it. It was also mentioned that the merger of t-mobile in to the new company everything everywhere will probably delay the unlocking further. I am getting the impression that I will be forced to take out a t-mobile contract as it stands. Anyone out there have any recent knowledge about t-mobile unlocking. Many thanks!
I would like some advice. I would like to send test data at intervals from a client to a cloud server and measure the time taken for it to arrive at the server. At the same time, pinging the cloud server at intervals and measuring the roundtrip latency. [more inside]
I would like to know what is the best approach for measuring a cloud provider's network latency and jitter e.g. Amazon EC2. While a single ping on the command line can achieve a round trip latency snapshot for that one moment, I was looking for something more comprehensive and thorough. Are there any software tools out there that are particularly recommended and hopefully easy to use for measuring at intervals, network latency & jitter, preferably in Windows? Is round trip latency or end to end latency the best metric to consider? Ping provides roundtrip although if the packet came back the same route it came, then end to end could be found by dividing by 2. Latency and jitter increases in proportion to server load. How could I ramp up server load to let's say a specified percentage? Many thanks!
I am learning in college about setting up and configuring Slackware Linux and I am looking for a newbie friendly book. Areas covered includes FTP, telnet, Samba, NFS, Email, port mappers/scanners. While there are certainly many books out there, Slackware appears to be a fair bit different from most other debian and redhat based distros so I am not sure about a) what would be a good book and b) a book that is relevant for Slackware Linux. Could anyone suggest an excellent book suitable for Slackware and covering these networking areas in newbie friendly terms. Many thanks!
I am looking to do a project on the effects of latency on cloud computing, specifically latency impacting on Amazon EC2 virtual machines and I am trying to get my head around it. EC2 is an Infrastructure As A Service cloud product. Unfortunately, I do not have much experience with it. I haven't found alot on the internet on this area; has anyone seen any information on this subject? Could anyone make suggestions about appropriate ways to do latency benchmarking in this area. What kind of things ought I be looking to include in any benchmark tests. How exactly do others go about measuring latency for Amazon EC2. Are there any software tools out there which will help.
