• The canonical "blocking BitTorrent" question

  - by Aphex5

  How can one block, or severely slow down, BitTorrent and similar peer-to-peer (P2P) services on one's small home/office network? In searching Server Fault I wasn't able to find a question that served as a rallying point for the best technical ideas on this. The existing questions are all about specific situations, and the dominant answers are social/legal in nature. Those are valid approaches, but a purely technical discussion would be useful to a lot of people, I suspect. Let's assume that you don't have access to the machines on the network. With encryption use increasing in P2P traffic, it seems like stateful packet inspection is becoming a less workable solution. One idea that seems to make sense to me is simply throttling down heavy users by IP, regardless of what they're sending or receiving -- but it doesn't seem many routers support that functionality at the moment. What's your preferred method to throttle P2P/BitTorrent traffic? My apologies if this is a dupe.

• Limit maximum incoming connections to a port using iptables

  - by Harley

  I have a server that has apache listening on a number of ports. Some ports are used for configuring the server, and another is used to download large files. My problem is that when I have a large number of clients downloading files, the web interface is uncontactable. I would like to limit the number of clients connecting on the "large file" port so that apache always has available connections to configure the server. A REJECT is fine, the client trying to download the file will back off and retry later. Each client only has one connection open to the server at a time, so limiting by IP won't work. I know I could put something in front of apache to manage this, but I'd really like to do it in iptables, without adding more software.

• Postfix how to triggering my script when outgoing email status is sent?

  - by Laszlo Malina

  I want to run a program when postfix has successfully sent out a mail (local or remote). I would like to pass the headers to program and if possible also the destination ip or address (exclude spam filter delivery). I just have an idea: Delivery Status Notification processing via uniqe transport program, but I'd prefer the above. My goal is to be recorded lifetime (events) of email: it came, it went out (from, to, subject, datetime, message id, message status: bounce, sent). I would only need the state of the outgoing mail, because incoming and bounce program is working. It is possible to trigger a program (similar to a transport pipe/spawn) or DSN "cheat" stay? Thanks in advance for any reply!

• access VPN machine macosx same subnet

  - by matheszabi

  I would like to access the office machine, which has a fixed IP, and is available only in its local LAN. Let say 192.168.1.100. I have a VPN with username/password connection and I am trying to access the office machine from another location, i.e., another LAN, which has the same subnet: 192.168.1.50. I am using MacOSX 10.8. I have checked the "send all trafic over VPN connection, but I think it looks like it doesn't care and is searching in Local. I do not have admin privileges and can't request to make changes to the network settings in both LANs. Is there any way to connect to the desired remote machine?

• how to limit upload bandwidth per user in linux?

  - by Gihan Lasita

  Can anyone provide the tc command to limit upload bandwidth per user in Debian Lenny? I found that to mark packets per user with iptables I can use the following command iptables -t mangle -A OUTPUT -p tcp -m owner --uid-owner testuser -j MARK --set-mark 500 but I have no idea how to use tc update by running following commands, i managed to limit testuser upload bandwidth to 10Mbit iptables -t mangle -N HTB_OUT iptables -t mangle -I POSTROUTING -j HTB_OUT iptables -t mangle -A HTB_OUT -j MARK --set-mark 30 iptables -t mangle -A HTB_OUT -m owner --uid-owner testuser -j MARK --set-mark 10 tc qdisc replace dev eth0 root handle 1: htb default 30 tc class replace dev eth0 parent 1: classid 1:1 htb rate 10Mbit burst 5k tc class replace dev eth0 parent 1:1 classid 1:10 htb rate 10Mbit ceil 10Mbit tc qdisc replace dev eth0 parent 1:10 handle 10: sfq perturb 10 tc filter add dev eth0 parent 1:0 prio 0 protocol ip handle 10 fw flowid 1:10 now the problem is, i do not want to limit testuser's FTP bandwidth but by running above commands FTP speed also limited to 10Mbit.

• Grant relay to servers based on AD security group membership

  - by john

  We're moving our relay from an Exchange 2003 server to an Exchange 2010 server. I was hoping the "Grant or deny relay permissions to specific users or groups" option would still be available in some form, but I can't find out how to do it. I've read up on recieve connectors and so far I can't get it to work. I have edited the security on the Recieve Connector to allow the following extended rights to the group and added computer accounts to that group: Accept Routing Headers Bypass Anti-spam Submit to Server Accept any Sender Accept any Recipient Then I suddenly realised while testing... How would the receive connector resolve the permission to a particular AD object, maybe a reverse DNS lookup? What I'd like to know is if what I'm trying to achieve is possible, and how it would be possible. I would rather not revert to an IP-based list as this is not as manageable, and I'm trying to avoid creating static IPs/reservations for a number of workstations that would otherwise not need them.

• My site was recently attacked. What do I do?

  - by ChrisH

  This is a first for me. One of the sites I run was recently attacked. Not at all an intelligent attack - pure brute force - hit every page and every non-page with every extension possible. Posted with garbage data to every form and tried to post to some random urls too. All tod, 16000 requests in one hour. What should I do to prevent/alert this kind of behavior? Is there a way to limit the request/hr for a given ip/client? Is there a place I should be reporting the user to? They appear to be from China and did leave what seems like a valid e-mail.

• Laptop connects to other network but not to my home wireless

  - by Nilesh

  My home network's wireless SSID is say "XYZ" I also have an ethernet wire from the same router. I have two laptops A and B Earlier both A and B were able to connect to my home internet through the ethernet and wireless. Suddenly, the laptop B can no longer connect to XYZ or through ethernet. When I do plug the wire, i get the connection icon all green but when I try to access any web page it errors out (page not found) But strangely laptop B connects to my neighbours wireless SSID "ABC". I have also tested laptop B with other networks and it connects fine. Laptop A and many other devices still connect fine with my home wireless "XYZ" Strange thing is when my laptop B connects wireless through XYz, it gets the IP address but then none of the browsers (chrome,firefox, IE) can show any web pages. What settings should I be checking on laptop B that is preventing it to connect to my home internet. Thank you

• On RouterOS, how will transparent proxying (with DNAT) affect reporting of netflows?

  - by Tim

  I have a box running Mikrotik RouterOS, which is set up to do transparent web proxying, as described here. In short, this means that I have a firewall rule for destination NAT causing any port 80 traffic to get redirected to port 8080 on the router, which is received by the Mikrotik local web proxy. The local web proxy then makes the web request on the client's behalf, in this case to a parent web proxy server (which in turn does the real web request). My question is, how will this two-part process get reported in the logging of traffic flow information (netflows)? Looking at the logged information, what I seem to be seeing is this: One flow recorded from client machine (private IP) to remote proxy (8080) Another flow recorded from router to remote proxy (8080) The original request that the client made to port 80 isn't recorded. I want to write code to analyse traffic usage, so I want to be sure I'm not losing information if I discard the latter of these.

• Connected to internet but can't browse after trying to remove Covenant Eyes

  - by Joanna

  I recently got a MacBook Pro. It connects to ethernet\wifi and has internet but when I open Safari or Firefox, nothing happens. I get a timeout for all websites. I had Covenant Eyes on my Mac before and tried to remove it. My friends who work with computers have tried everything (ping, nslookup etc). Network diagnostics show no problems I can see I'm connected through ifconfig because I get an IP. I also get a response pinging www.google.gr. There are no proxies set in my Network preferences. Any ideas?

• Debugging Connection Issues Between Two Linux Servers

  - by clickfault

  I have two CentOS 5 servers running iptables and apf. I am having issues connecting with ssh from server 1 to server 2. I can connect from server 1 to a third server and from that third server to both 1 and 2. In all cases I am using the IP address and not a host name. I have stopped iptables and apf on all servers and it doesn't seem to change anything. What is the best way to debug this process?

• Apache Configuration Issue - website without www going to default site

  - by Brian

  I have included a copy of my virtual host file for apache below. (However I have hidden the ip address and domain name for now) My problem is that the following work: www.mydomainnamehere.org www.mydomainnamehere.com mydomainnamehere.com This one doesn't work: mydomainnamehere.org - instead of going to the document root listed below, it goes to the document root of the default site. What could be causing this? <VirtualHost [ipaddresshidden]:80> ServerAdmin [email protected] ServerName mydomainnamehere.org ServerAlias www.mydomainnamehere.org ServerAlias mydomainnamehere.com ServerAlias www.mydomainnamehere.com DocumentRoot /home/www/mydomainnamehere.org/html/ ErrorLog /home/www/mydomainnamehere.org/logs/error.log CustomLog /home/www/mydomainnamehere.org/logs/access.log combined </VirtualHost>

• Dual-WAN router

  - by aix

  I am looking for a router that would fit the following requirements: Two WAN interfaces: the primary is PPPoE, the secondary will link to a GigE port on another router (a 100Mbps link will suffice); Two (ideally four) GigE LAN ports; No requirement for a firewall; No requirement for Wi-Fi; Inexpensive. The plan for the two WAN interfaces is as follows. All outbound traffic will go to the primary, with exceptions based on destination IP/subnet or possibly on src+dest IPs/subnets. Such exceptions should be routed to the secondary. It would be very nice if, should the primary go down, the secondary would automatically take over for all outbound traffic. I am reasonably sure that I can put something together based on dd-wrt. However, I'd like to hear from you what alternatives are out there (especially something easier to set up for my use case, even if it means paying more for the hardware.)

• Windows 7 add printer, cancelled, but port still in use. How to remove?

  - by Jake

  I tried to add a network printer at www.xxx.yyy.zzz, but halfway it when it asked for a driver, I cancelled it because I do not have the driver at hand. Later when I try to add again, it tells me the port (www.xxx.yyy.zzz), which is automatically specified as the same as the IP for the printer, is already in use and then suggest www.xxx.yyy.zzz_1 Now, I cannot find the www.xxx.yyy.zzz printer anywhere such that I can remove it and use back the same port. How should I do it? Any ideas? Thanks.

• VirtualBox "Bridged Adapter" when host NIC is turned off

  - by chris_l

  Hi, I'm running Linux (Debian Etch) in a VirtualBox VM on my MacBook. I usually ssh from my Mac terminal to the guest machine. I also want to access the internet from my guest, so I set up my host's WLAN card (en1) as a bridged adapter for eth0 on the client. This works fine, but when I turn off the WLAN card (e.g. to reduce battery consumption), I'd still like to ssh from my host to the guest. This fails of course, because en1 loses its IP address. Is a bridged adapter the best option for what I want to do? How can I make it work? (A simple "ifconfig en1 add 10.0.0.4" didn't do the trick...) Thanks Chris

• Source of Unexplained Requests in Server Logs

  - by Synetech inc.

  Hi, I am baffled by some entries in my server logs, specifically the web-server logs. Other than normal, expected traffic, I have noticed three types of request errors (eg 404, etc.): Broken links, ie links from old, external pages that point to pages that are no longer here Sequences of probes, ie some jerk trying to hack in by scanning my server for a series of exploitable admin type pages and such What appear to be completely random requests for things that have never existed on the server or even have anything to do with the server, and appear by themselves (ie not a series of requests like the probes) Could it somehow be a mistyped URL or IP? That’s about the only thing that I can think of, but still, how could I get a request on say, foobar.dyndns.org (12.34.56.78) for something like www.wantsfly.com/prx2.php or /MNG/LIVE or http://ant.dsabuse.com/abc.php?auth=45V456b09m&strPassword=X%5BMTR__CBZ%40VA&nLoginId=43. (Those are a few actual requests from my logs.) Can someone please explain scenario three to me? Thanks.

• How to route traffic through a specific SOCKS proxy on a per-app basis?

  - by GJ.

  I'm running a certain desktop app (actually via AIR if it makes any difference) which doesn't have any built-in proxy configuration settings. I need to get all traffic just from this app directed through a secure SOCKS proxy. This implies I can't use the global network preferences, as these would affect many other apps. Is there any way to force all network communication through a given SOCKS proxy on a per-app basis? It would also be helpful to know if there's a way to perform such routing globally, based on specific IP addresses (as this could allow for some reasonable workaround).

• Hosting several domains on one server using IIS 7

  - by Øyvind Knobloch-Bråthen

  I have created several web sites inside IIS7 on my server. All of them use the same ip and port, but different host names. Currently I have set the host name to www.mydomain.com. Now my question is, how do I get my actual domains to target the different sites on my server. Second question. Can I set my host name to only mydomain.com to make sure that all requests to that domain is handeled by the same application? Primarily, I want both www.mydomain.com and mydomain.com to work when the user types the address in their browser.

• How to correctly set up iWARP? Preferably on loopback

  - by ajdecon

  iWARP is a protocol for doing remote direct memory access (RDMA) on top of TCP/IP, so that it can work with Ethernet and other network types as opposed to Infiniband. It works with many of the standard IB interfaces - the IB verbs, for example - so it's all pretty transparent. I'm doing some IB-verbs programming (mostly for the sake of learning about how they work better), and it'd be wonderfully convenient for me if I could use iWARP to do RDMA over my loopback interface, so that I could test some of my code without getting on our IB-connected cluster. :-) But I cannot figure out how to get a "local development environment" set up: there are no tutorials I'm aware of for even setting up iWARP from scratch on a server or a network interface. Can anyone give me a tutorial or point me in the right direction? Environment is Fedora 16 running in VirtualBox.

• dig and dig -x are answering different

  - by erdemkeren

  I don't want the name provider to manage my records. I want to handle it myself. So I installed bind9 and made some configurations reading some articles and following some examples. bind didn't show any error after I created/edited the required files but; When I write `dig www.foo.com, I see the IP of the advertisement page of my name provider. But when I write dig -x server_ip_address; I see the name I purchased. What am I doing wrong? Can't a server be the nameserver of it's own? Is it a must to configure the records from the company I bought the name from? By the way, I realised that, my previous question was not clear, I deleted it, and asking the same question in a different way.

• Do I need a VPN to secure communication over a T1 line?

  - by Seth

  I have a dedicated T1 line that runs between my office and my data center. Both ends have public IP addresses. On both ends, we have a T1 routers which connect to SonicWall firewalls. The SonicWalls do a site-to-site VPN and handle the network translation, so the computers on the office network (10.0.100.x) can access the servers in the rack (10.0.103.x). So the question: can I just add a static route to the SonicWalls so each network can access each other with out the VPN? Are there security problems (such as, someone else adding the appropriate static route and being able to access either the office or the datacenter)? Is there another / better way to do it? The reason I'm looking at this is because the T1 is already a pretty small pipe, and having the VPN overhead makes connectivity really slow.

• I just got a linode VPS a week ago and I've been flagged for SSH scanning...

  - by meder

  I got a 32-bit Debian VPS from http://linode.com and I really haven't done any sort of advanced configuration for securing it ( port 22; password enabled ). It seems somehow there is ssh scanning going on from my IP, I'm being flagged as this is against the TOS. I've been SSHing only from my home Comcast ISP which I run Linux on. Is this a common thing when getting a new vps? Are there any standard security configuration tips? I'm quite confused as to how my machine has been accused of this ssh scanning.
