• Relation between TCP/IP Keep Alive and HTTP Keep Alive timeout values

  - by Suresh Kumar

  I am trying to understand the relation between TCP/IP and HTTP timeout values. Are these two timeout values different or same? Most Web servers allow users to set the HTTP Keep Alive timeout value through some configuration. How is this value used by the Web servers? is this value just set on the underlying TCP/IP socket i.e is the HTTP Keep Alive timeout and TCP/IP Keep Alive Timeout same? or are they treated differently? My understanding is (maybe incorrect): The Web server uses the default timeout on the underlying TCP socket (i.e. indefinite) and creates Worker thread that counts down the specified HTTP timeout interval. When the Worker thread hits zero, it closes the connection.

• Determining the hostname/IP address from the MX record in PHP

  - by pmmenneg

  Hi there, have a basic email domain validation script that takes a user's email domain, resolves the IP address from that and then checks that against various published blacklists. Here is how I am determining the IP: $domain = substr(strchr($email, '@'), 1); $ip = gethostbyname($domain); The problem is that some email address domains, such as [email protected], use an MX record rather than an A record, so using gethostbyname('alumni.example.net') will fail to resolve. I know when a user's email is using an MX in the email itself by using the PHP checkdnsrr function, but once at that stage am a little stuck as to how to proceed. In theory, I could parse out the 'root' domain, i.e. 'example.net' and check it, but I've not found reliable regex that can handle this task when the user could easily have an email the format of [email protected]... So, any suggestions on how to best tackle this??

• Why GPRS modem provides embedded TCP/IP stack

  - by Christian Madsen

  My colleague and I are mining the GPRS MODEM market for a module suitable for use with embedded Linux. During the market scan, we see that several vendors highlight that their MODEMs include an embedded TCP/IP stack. This makes me wonder: when we are using embedded Linux which already contains a TCP/IP stack and connects using PPP, will it make use of the stack included in the GPRS MODEM at all? My current assumption is that the stack is included for use with tiny microcontroller OS that do not supply their own stack. Also some of the MODEMs allow for running small applications IN the MODEM baseband processor which could explain the embedded stack... So: is the TCP/IP stack supplied by the GPRS MODEM superfluous when using it with an HL OS or did I overlook something?

• How determine database server IP via UDP in Java

  - by Wolfgang Lenhard

  Hi, I am writing clients in Java that store the data on a database server. So far, the IP and Port of the server has to be specified in the client's settings manually. I have heard, that it is possible to automatically determine the IP of database servers via broadcast / multicast / UDP (I am not familiar with these concepts). Question: Is there a way to retrieve the IP adresses of all available database-servers in the local network? I am working with the h2 database system so far. Bye, Wolfgang

• Store IPv6 in database

  - by poru

  What's the best practise to store IP's with PHP in MySQL database? There's a function called ip2long - but this is just for IPv4. But what about IPv6? I know a php function that is for IPv6 IP's, but it doesn't work on Windows with PHP < Version 5.3

• Red Hat cluster: Failure of one of two services sharing the same virtual IP tears down IP

  - by js.

  I'm creating a 2+1 failover cluster under Red Hat 5.5 with 4 services of which 2 have to run on the same node, sharing the same virtual IP address. One of the services on each node needs a (SAN) disk, the other doesn't. I'm using HA-LVM. When I shut down (via ifdown) the two interfaces connected to the SAN to simulate SAN failure, the service needing the disk is disabled, the other keeps running, as expected. Surprisingly (and unfortunately), the virtual IP address shared by the two services on the same machine is also removed, rendering the still-running service useless. How can I configure the cluster to keep the IP address up?

• Need to change ip address in app.config in runtime without runnning as admin

  - by djerry

  Hey guys, There's a lot of post saying how to change info in the app.config and there are posts that say you shouldn't edit info in the app.config but store info in user folders. I understand these topics. But what i want is a combination of both. I have a wcf setup for my client in an app.config, which contains the endpoint address to which it should connect. When The server changes ip, or when a client is installed on a computer in another company, the user should be able to insert another ip-address which should be stored in the app.config. This cannot be stored in a file in appdata or something like that, as the client reads the info in the app.config on startup. How can i write (so remember the new ip-address) in the app.config when the client is installed in program files, the UAC is enabled and the program isn't run as an admin? Thanks in advance.

• List of IP addresses/hostnames from local network in Python

  - by joshhunt

  How can I get a list of the IP addresses or host names from a local network easily in Python? It would be best if it was multi-platform, but it needs to work on Mac OS X first, then others follow. Edit: By local I mean all active addresses within a local network, such as 192.168.xxx.xxx. So, if the IP address of my computer (within the local network) is 192.168.1.1, and I have three other connected computers, I would want it to return the IP addresses 192.168.1.2, 192.168.1.3, 192.168.1.4, and possibly their hostnames.

• Obtaining the server IP address in WCF?

  - by chris

  How can I obtain the server IP address that was used to connect to a service? The server has multiple IP addresses and I need to know which one the client is connected to. So far I only found that OperationContext.Current.EndpointDispatcher.EndpointAddress and OperationContext.Current.Channel.LocalAddress contain the address from .config (e.g. localhost) OperationContext.Current.IncomingMessageProperties.Via contains the Url that the client used to connect to the server (but this might just be a name from the clients hosts file). EDIT - Sorry, I wasn't being clear enough: The server needs to know which of its IP addresses were used by the client. E.g. the server has the addresses 10.0.0.1 and 10.0.0.2. when processing the request the server service needs to know if 10.0.0.1 or 10.0.0.2 was used by the client to connect to it.

• precise geolocalization via IP

  - by meo

  I tied the iPad the other day, and was amazed about the precision of the geolocalization by ip. Actually there is this action against hunger in the world that shows you very precisely where the persons are located that have took part to this petition: http://www.1billionhungry.org/meodai/impact/ I would like to integrate that in one of my projects. I took a look at the source but i could not figure out how they did it. Can someone help me out? is there a web service for that? Is the google map api doing this or are they using an other service? PS: Its not just the country/region of your IP/ISP IP that the service gives back, its a pretty precise positioning.

• What is the total amount of public IPv4 addresses?

  - by Earlz

  Yes, I am needing to know what the total number possible IPs in the public IPv4 space. I'm not sure where to even get a neat list of all the IP address ranges, so could someone point me to a resource to calculate this myself or calculate the total number of IPs for me? Also, by Public IPs I mean not counting reserved or private-range IP addresses.. Only the ones that can be access through the internet.

• TCP/IP and UDP Questions and very small application for interview

  - by Shantanu Gupta

  I am going for an interview day after tomorrow where i will be asked vaious questions related to TCP/IP and UDP. As of now i have prepared theoritical knowledge about it. But now I am looking up for gaining some practicle knowledge related to how it works in a network. What all is going in vaious .NET classes. I want to create a very small application like a chat or something that can make me all these concepts very much clear. Could you please suggest some questions related to TCP/IP that you generally ask or that you might have faced. How communication is going from server to client. Right now I am studying TcpClient, TcpListener and UdpClient Class but I want to implement all of them so as to get aware about its working. Is Chat application a Tcp/IP application ? I would appreciate your help.

• converting ip to long string in mysql command !

  - by Mac Taylor

  hey guys I'm trying to use ip2country technique to show my users'flags simple thing to do is to write a sql statement and show users from session table and then query to see if their ip is in what range and show their flags it simple but dengerous becuase when showing 300 users online and fetching from session table and then query once again ip2country table to get the flags there will be surelly memory overusage problem now i wrote a query to make it in one query : SELECT s.session_ip,ipc.* FROM session s left join ip2country ipc ON ipc.ip_lo<=s.session_ip AND ipc.ip_hi>=s.session_ip WHERE s.session_time > '".( time() - 60) )."' now its clear above query is wrong cause ips saved in ip2country table is long string 1000013824 and ips saved in session table are real ip e.g. 193.169.0.0 now i know how to convert from ip to long in php ip2long() but is there any command in mysql to do it with out building another query !?

• Capture IP packets on Dialup connection - Windows 7

  - by Assaf Levy

  Our product utilizes (the wonderful) Winpcap to capture ip packets from all devices with an IP address and analyze them in real time. Unfortunately, we discovered that it does NOT capture any packets on dialup (e.g. PPP) connections on Windows 7, and that there are no near-term plans for enabling this (1). So we need something else. Microsoft Network Monitor and Windows Packet Filter are two options that surfaced during a bit of googling, but before delving into research I wanted to ask the experienced: what are out options, given the following requirements: Capture all in/outbound IP packets on the machine. Complete background processing - no UI should be involved. Support Windows Vista / 7. Performance (user should not feel the difference). Thanks in advance.

• Python access an object byref / Need tagging

  - by Aaron C. de Bruyn

  I need to suck data from stdin and create a object. The incoming data is between 5 and 10 lines long. Each line has a process number and either an IP address or a hash. For example: pid=123 ip=192.168.0.1 - some data pid=123 hash=ABCDEF0123 - more data hash=ABCDEF123 - More data ip=192.168.0.1 - even more data I need to put this data into a class like: class MyData(): pid = None hash = None ip = None lines = [] I need to be able to look up the object by IP, HASH, or PID. The tough part is that there are multiple streams of data intermixed coming from stdin. (There could be hundreds or thousands of processes writing data at the same time.) I have regular expressions pulling out the PID, IP, and HASH that I need, but how can I access the object by any of those values? My thought was to do something like this: myarray = {} for each line in sys.stdin.readlines(): if pid and ip: #If we can get a PID out of the line myarray[pid] = MyData().pid = pid #Create a new MyData object, assign the PID, and stick it in myarray accessible by PID. myarray[pid].ip = ip #Add the IP address to the new object myarray[pid].lines.append(data) #Append the data myarray[ip] = myarray[pid] #Take the object by PID and create a key from the IP. <snip>do something similar for pid and hash, hash and ip, etc...</snip> This gives my an array with two keys (a PID and an IP) and they both point to the same object. But on the next iteration of the loop, if I find (for example) an IP and HASH and do: myarray[hash] = myarray[ip] The following is False: myarray[hash] == myarray[ip] Hopefully that was clear. I hate to admit that waaay back in the VB days, I remember being able handle objects byref instead of byval. Is there something similar in Python? Or am I just approaching this wrong?

• No Internet access while being connected to VPN using Cisco VPN Client 5.

  - by szeldon

  Hi, I have an access to corporate VPN using Cisco VPN Client 5.0.00:0340, but when I'm connected to it, I don't have an Internet access. I'm using Windows XP SP3. As it was suggested here http://forums.speedguide.net/showthread.php?t=209167 , I tried to enable "Allow local LAN Access" but it doesn't work. I also tried a second solution - deleting entry using "route" command, but it didn't help. I used "route delete 192.168.100.222". It's a third day of my attempts to solve this issue and I don't have an idea what else to do. I'm not very experienced in VPN stuff, but I know something about networking. Basing on my knowledge, I think that it's theoretically possible to achieve Internet access using my local network and only corporate stuff to be routed using VPN connection. I think that theoretically this should look like this: every IP being inside by corporation - VPN interface IP every other IP - my ethernet interface I've tried many possibilities of how to change those routes, but neither of them work. I'd really appreciate any help.

• eth0 and eth1 both assigned same IP on boot

  - by Banjer

  I have a physical SLES 11 SP2 server on a Sun Fire x4140 that is giving me problems with networking upon reboot. The NICs are onboard. The networking appears successful during boot, but network services such as nfs fail hard. This is because eth0 and eth1 are both receiving the same configuration and are both ifup-ed. Once everything times out and I'm at the console, ifconfig shows that eth0 and eth1 are UP and running with the same IP. Attempting to ping anything in that subnet fails. Restarting the network service fixes the issue. eth0 is the correct NIC that should be configured as primary, per the MAC address. Question: Whats causing eth1 to be brought up with the same config as eth0?? I do not have a config script set up for eth1: banjer@harp:~> ls -la /etc/sysconfig/network/ total 104 drwxr-xr-x 6 root root 4096 Jun 11 12:21 . drwxr-xr-x 6 root root 4096 Apr 10 09:46 .. -rw-r--r-- 1 root root 13916 Apr 10 09:32 config -rw-r--r-- 1 root root 9952 Apr 10 09:36 dhcp -rw------- 1 root root 180 Jun 11 12:21 ifcfg-eth0 -rw------- 1 root root 180 Jun 11 12:21 ifcfg-eth3 -rw------- 1 root root 172 Feb 1 08:32 ifcfg-lo -rw-r--r-- 1 root root 29333 Feb 1 08:32 ifcfg.template drwxr-xr-x 2 root root 4096 Apr 10 09:32 if-down.d -rw-r--r-- 1 root root 239 Feb 1 08:32 ifroute-lo drwxr-xr-x 2 root root 4096 Apr 10 09:33 if-up.d drwx------ 2 root root 4096 May 5 2010 providers -rw-r--r-- 1 root root 25 Nov 16 2010 routes drwxr-xr-x 2 root root 4096 Apr 10 09:36 scripts On a side note, eth3 is also configured with an IP in a different subnet, but this has not posed any problems.

• IIS SSL is taking all IPs although it is told not to

  - by Martin Sall

  I have a testing system where IIS Express on Windows 7 SSL website has to live together with Cerberus FTP server SSL website (Cerberus FTP has a built-in web server for HTTP uploads). I have set up Windows to use two IPs from my router 192.168.1.128 (for IIS SSL Web Site, using a self-generated SSL certificate for now) 192.168.1.129 (for Cerberus FTP built-in SSL Web Site) In IIS I have set web site binding to use only the IP 192.168.1.128. But still when I launch Cerberus, it says - cannot bind 192.168.1.129:443. I tested in Firefox - indeed, when I go to 192.168.1.129 (or even localhost), I do not get “Unable to connect“ page as expected, but “The connection was reset” instead. IIS is still occupying those IPs, although it is not serving the website on those IPs. When I stop the IIS website, Cerberus FTP Website launches without problems. But then I cannot launch IIS web site, it tells - "The process cannot access the file because it is being used by another process". Why is IIS SSL web site still occupying all IPs?

• need advice on data center move, communication with both facilities during transition

  - by Brian Roden

  We are beginning the process of moving to a new facility. Office and warehouse operations will both be moving, and we must get shipping operations up and running at the new location while continuing to ship from the old location. Our contract with some third-party warehouse tenants requires two business day turnaround (only weekends and holidays excluded), so we can't have major downtime during the move. We would like to keep our 172.16.60/61.xxx internal address space in use throughout the move. Is it possible to keep using this same internal range, and have our existing WatchGuard Firebox 520 and whatever router we get for the other location (preferably the same model) just treat both locations as one network, leaving our host IPs the same throughout the move? Renumbering the servers when they move isn't a big deal, but our wireless terminals for order picking in the warehouse have fixed IPs (and a fixed IP, non-DNS reference to the host they speak with) and would be a massive undertaking to reconfigure when the servers move (each device would have to be reconfigured at least 2 times -- some when we start using them in the new building and the host is still here, all of them in both locations when the host moves to the new building, and the rest when they finally make the move to the new building). We're trying to avoid that if possible.

• NTLM, Kerberos and F5 switch issues

  - by G33kKahuna

  I'm supporting an IIS based application that is scaled out into web and application servers. Both web and applications run behind IIS. The application is NTLM capable when IIS is configured to authenticate via Kerberos. It's been working so far without a glitch. Now, I'm trying to bring in 2 F5 switches, 1 in front of the web and another in front of the application servers. 2 F5 instances (say ips 185 & 186) are sitting on a LINUX host. F5 to F5 looks for a NAT IP (say ips 194, 195 and 196). Created a DNS entry for all IPs including NAT and ran a SETSPN command to register the IIS service account to be trusted at HTTP, HOST and domain level. With the Web F5 turned on and with eachweb server connecting to a cardinal app server, when the user connects to the Web F5 domain name, trust works and user authenticates without a problem. However, when app load balancer is turned on and web servers are pointed to the new F5 app domain name, user gets 401. IIS log shows no authenticated username and shows a 401 status. Wireshark does show negotiate ticket header passed into the system. Any ideas or suggestions are much appreciated. Please advice.

• Two hosts on same subnet can't see each other

  - by Joey Hewitt

  I've got two routers with two separate public IP addresses on the same subnet, but I can't get them to talk to each other. Both are connected to the internet (ISP-provided gateway) via Ethernet ports provided by the landlord, but I don't have access to or knowledge of how those are physically connected or the protocols used to get back to the ISP. I can ping either from the outside, but they can't ping each other. Traceroutes in and out look the same, and they receive the same gateway over DHCP. I can ping other IPs on the subnet, so I assume this is not any sort of intentional isolation for security/privacy. Since I'm in a setup where my landlord provides internet and we don't have contact with the ISP, I can't really ask the ISP for help (doubt the landlord would know much either.) The situation is similar to the diagram at this question, but instead of the two servers, there's another router coming off the (presumed) switch, and I don't have access to the switch. I've tried giving them static routes to each other with the ISP internet gateway as the gateway, but that's not working. One is a Linksys WRT54GL running DD-WRT, the other is a Netgear WGR614v7, although I could get something more capable if necessary. I'd like to keep them each connected directly to the ISP on their WAN ports, but I can have an ethernet cable between them if necessary - I'm wondering if there's a way without that, and if there isn't, I'd appreciate advice on how to get that working. Sorry this is so nitpicky; there are reasons for all the constraints, but they don't apply to the real question, so I left them out. ;) Thank you!

• hosting company blocking google bots and crawlers [closed]

  - by Jayapal Chandran

  Hi, I am having a site for the past three years and it is very active for the past two years. Until not the site is working well and also now but not after the hosting company blocked google bots. Many pages appeared in the first page of the google search. After they started blocking i couldn't see my links in the first page instead they appeared after 5 pages or they did not appear at all. Will hosting companies be so stupid that they block and dont mention it to their users. They want to protect themselves by making the websites at stake. I display google ads and not this month i got only half for this 10 days. I have made requests to other hosting companies like blue host and monster host that i wan to transfer my domain by making a condition that the will not block google bots which stops the business indirectly. so any kind of help will be helpful. how can i claim what i lost from the hosting company. what other hosting companies consider the users (by informing the events like changing the IP or blocking google bot.) It was really working hard to bring up my site but these people just crashed down my site in a few days. :-(
