Outgoing SMTP Servers
by Dennis Burgess 01 Nov '11

01 Nov '11

I am curious about what network operators are doing with outbound SMTP traffic. In the past few weeks we have ran into over 10 providers, mostly local providers, which block outbound SMTP and require the users to go THOUGH their mail servers even though those servers are not responsible for the domains in question! I know other mail servers are blocking non-reversible mail, however, is this common? And more importantly, is this an acceptable practice? Most of our smaller ISPs that we support; we allow any outbound SMTP connection, however we do watch residential users for 5+ outbound SMTP connections at the same time. But if the ISP has their own mail servers, and users wish to relay though them, we basically tell them to use their mail server that they contract with. What is the best practice? ----------------------------------------------------------- Dennis Burgess, Mikrotik Certified Trainer Link Technologies, Inc -- Mikrotik & WISP Support Services Office: 314-735-0270 <tel:314-735-0270> Website: http://www.linktechs.net <http://www.linktechs.net/> LIVE On-Line Mikrotik Training <http://www.onlinemikrotiktraining.com/> - Author of "Learn RouterOS" <http://routerosbook.com/>

Random five character string added to URLs?
by Christopher J. Pilkington 01 Nov '11

01 Nov '11

This might be off-topic, my apologies if so. I seeing requests against a server with initial GET requests in the form: GET /[a-zA-Z]{5}/pagename.html pagename.html being optional. The 5 character string seems to be random. This GET always results in a 404, as our servers don't have these paths. The second request seems to always the same without the modified path, which results in a 20. I initially suspected this was something from an attack or DOS tool, but the traffic doesn't fit such a pattern. Is anyone familiar with what device/service behaves in this fashion? Clearly something layer 7 is between the clients and the server. Provider is without clue regarding this. Google results in many GoDaddy users complaining of same; the server in question is not hosted with them, but I suspect they may be doing something similar. Thanks, -cjp

consumer DSL problems
by Mike Reed 01 Nov '11

01 Nov '11

Hi folks, It would seem that my home broadband provider (Orange, formerly known as Wanadoo/Freeserve) have made some networking changes at the weekend. The first I knew of it was when my DSL router refused to connect. It's a vendor-supplied Siemens Gigaset SE572. While it's probably not the best router in the world (most consumer routers are risible), it was generally fine. On complaint, they tell me it's 'old'. Closer inspection reveals it's picking up the DSL carrier signal fine, but failing during LCP negotation Is there a common policy on rendering vendor-supplied CPEs unusable? As a network operator to residential users, would you notify any potentially affected users before making such a change? I am grateful for any insight. Kind regards, Mike

Manage an enterprise network? Please fill out my survey - for Science! :-)
by Justine Sherry 01 Nov '11

Hello! My name is Justine and I am a graduate student at UC Berkeley (http://cs.berkeley.edu/~justine) I'm doing a research project on middlebox appliances such as proxies, WAN optimizers, and firewalls. Middlebox appliances are any networking-related hardware other than routers and switches. I'd like to learn a little bit about how middleboxes are used in real world deployments in enterprises. Vendors often engage in surveys of this type - but the research community knows less than we'd like to about typical concerns in an enterprise network. If you work on network management in an enterprise, I'd love to hear about your experiences through this survey: https://docs.google.com/spreadsheet/viewform?hl=en_US&formkey=dHo1NGZ3eU04S… Some promises: (1) If you give me your email address, I will not give it to anyone else, nor will I add you to any annoying mailing lists. (2) If you mention the name of your organization, I will not share it with anyone else. (3) If I publish any data from this, statistics will be reported in aggregate. (4) I will not share the raw data from this survey with anyone other than my advisor, Professor Sylvia Ratnasamy (sylvia(a)eecs.berkeley.edu) Feel free to skip questions and please provide approximate answers if you have them. Finally, to thank you for your time, we'll enter you in to a lottery for a $100 Amazon gift card; we'll select two people to win and contact them on November 16. Thank you! If you have any questions or concerns, please contact me. Justine PS: The survey is here! Don't miss it! https://docs.google.com/spreadsheet/viewform?hl=en_US&formkey=dHo1NGZ3eU04S…
