  • Unable to add IPv6 address to sendmail access list

    - by David M. Syzdek
    I am running Sendmail 8.14.4 on Slackware 13.37. I have the following in my /etc/mail/access file and it works without any errors: Connect:127 OK Connect:10.0.1 RELAY # Net: office Connect:50.116.6.8 RELAY # Host: glider Connect:96.126.127.87 RELAY # Host: kite The above configuration also allows me to send an e-mail via IPv6 to a local user on the mail server. However, it does not allow my office to relay via IPv6. I have tried two ways of adding IPv6 networks to my access file. Method 1: Connect:127 OK Connect:10.0.1 RELAY # Net: office Connect:IPv6:2001:470:b:84a RELAY # Net: office Connect:50.116.6.8 RELAY # Host: glider Connect:96.126.127.87 RELAY # Host: kite Method 2: Connect:127 OK Connect:10.0.1 RELAY # Net: office Connect:[IPv6:2001:470:b:84a] RELAY # Net: office Connect:50.116.6.8 RELAY # Host: glider Connect:96.126.127.87 RELAY # Host: kite However whenever I try using either method 1 or 2, I am unable to relay e-mail messages through the host. /var/log/maillog entry: May 31 11:57:15 freshsalmon sm-mta[25500]: ruleset=check_relay, arg1=[IPv6:2001:470:b:84a:223:6cff:fe80:35dc], arg2=IPv6:2001:470:b:84a:223:6cff:fe80:35dc, relay=[IPv6:2001:470:b:84a:223:6cff:fe80:35dc], reject=553 5.3.0 RELAY # Net:office Test session from telnet: syzdek@blackenhawk$ telnet -6 freshsalmon.office.example.com 25 Trying 2001:470:b:84a::69...

  • CentOS 5.8 dig is not resolving ip-address

    - by travisbotello
    I'm running centos 5.8 on a local machine at home. Today I was trying to analyze the DNS-Lookup via dig. $ dig +trace -t A www.heise.de. This is giving me something like this as a response de. 172800 IN NS f.nic.de. de. 172800 IN NS z.nic.de. de. 172800 IN NS s.de.net. de. 172800 IN NS n.de.net. de. 172800 IN NS a.nic.de. de. 172800 IN NS l.de.net. ;; Received 344 bytes from 192.58.128.30#53(192.58.128.30) in 49 ms In contrast my dedicated CentOS machine is returning the following de. 172800 IN NS a.nic.de. de. 172800 IN NS n.de.net. de. 172800 IN NS f.nic.de. de. 172800 IN NS z.nic.de. de. 172800 IN NS l.de.net. de. 172800 IN NS s.de.net. ;; Received 344 bytes from 192.58.128.30#53(j.root-servers.net) in 32 ms As you can see, the last line is different. Any idea why my dedicated machine is giving me the host name of the responding DNS-Server and my local machine is only returning the ip-address? Thanks in advance UPDATE The reverse DNS-Lookup is working without any problems. Also, I just checked this on my local mac and...exactly the same problem occurs. Is it possible that this has to do with the local router/modem/ISP?

  • IP address reuse on macvlan devices

    - by Alex Bubnoff
    I'm trying to create easy to use and possibly simple testing environment for some product and got some strange behaviour of macvlan's. What I'm trying to achieve: make a toolset for one-line start/stop of lxc containers(via docker) bound to external ip(I have enough of it on host machine). So, I'm doing something like this: docker run -d -name=container_name container_image pipework eth1 container_name ip/prefix_len@gateway and pipework here does this: GUEST_IFNAME=ph$NSPID$eth1 ip link add link eth1 dev $GUEST_IFNAME type macvlan mode bridge ip link set eth1 up ip link set $GUEST_IFNAME netns $NSPID ip netns exec $NSPID ip link set $GUEST_IFNAME name eth1 ip netns exec $NSPID ip addr add $IPADDR dev eth1 ip netns exec $NSPID ip route delete default ip netns exec $NSPID ip link set eth1 up ip netns exec $NSPID ip route replace default via $GATEWAY ip netns exec $NSPID arping -c 1 -A -I eth1 $IPADDR And it works for first time per IP. But for second time and later packets for containers IP isn't getting into container, while all configuration seem fine. So it looks like this: External machine ? ping 212.76.131.212 ....silence....

  • Implementing Autocompletion in iPhone UITextField for contacts in address book

    - by nacho4d
    Hi, I would like to have a UITextField or UITextView in where as I do some input, alternatives will appear something similar to when you type an address in Mail Application, alternatives appear down and is possible tap them so get a better input user interface.(since there is no need to type the complete word or address or phone number) I do know how to fetch data from Address Book framework, also how to input text in UITextField/UITextView and its delegates but I don't know what kind of structure to use for fetching and showing data as the user do his/her input. I know basic CoreData if this matters, I hope I can get some help. UPDATE (2010/3/10): I don't have problem make a native-like GUI but I am asking about the algorithm, does any body knows what kind algorithm is best for this thing? maybe some binary tree? Or should I just fetch data from coredata everytime? Thanks Ignacio UPDATE (2010/03/28): I've been very busy these days, so I have not tried UISearchResults but it seems fine to me. BUT I wonder was there a necessity of deletion of the wining answer? I don't think is fair my reputation went down and couldn't see the winning answer. ;(

  • Encoding a email address that can be used as part of a URL in codeigniter

    - by freedayum
    Is there a way to encode a email address that can be used as a part of a url in codeigniter?. I need to decode back the email address from the url. What I am trying to do is just a -forgotten password recovery- thing. I send a confirmation link to the user's email address, the link needs to be like ../encodedEmail/forgottenPasswordCode (with the forgottenPasswordCode updated in the db for the user with the submitted email). When the user visits that link, I decode the email(if the email - forgottenPasswordCode pair is in the table), i allow them to reset their password (and i reset forgottenPasswordCode back to null). I could just do a loop -checking the table with a select query- (or) -set that forgottenPasswordCode column unique, so i keep generating on a insert failure(would that be a lot faster ?)- until I generate a forgottenPasswordCode that doesn't already exist in the table. But the guy I do this for would not accept it this way:). He wants the checking be done with the user's email, he thinks its much faster. I am working with codeigniter, I used its encode() function, it seems to produce characters like '-slashes-' at times that breaks the encoded-email-string. Any other ideas?

  • Generating %pc relative address of constant data

    - by Hudson
    Is there a way to have gcc generate %pc relative addresses of constants? Even when the string appears in the text segment, arm-elf-gcc will generate a constant pointer to the data, load the address of the pointer via a %pc relative address and then dereference it. For a variety of reasons, I need to skip the middle step. As an example, this simple function: const char * filename(void) { static const char _filename[] __attribute__((section(".text"))) = "logfile"; return _filename; } generates (when compiled with arm-elf-gcc-4.3.2 -nostdlib -c -O3 -W -Wall logfile.c): 00000000 <filename>: 0: e59f0000 ldr r0, [pc, #0] ; 8 <filename+0x8> 4: e12fff1e bx lr 8: 0000000c .word 0x0000000c 0000000c <_filename.1175>: c: 66676f6c .word 0x66676f6c 10: 00656c69 .word 0x00656c69 I would have expected it to generate something more like: filename: add r0, pc, #0 bx lr _filename.1175: .ascii "logfile\000" The code in question needs to be partially position independent since it will be relocated in memory at load time, but also integrate with code that was not compiled -fPIC, so there is no global offset table. My current work around is to call a non-inline function (which will be done via a %pc relative address) to find the offset from the compiled location in a technique similar to how -fPIC code works: static intptr_t __attribute__((noinline)) find_offset( void ) { uintptr_t pc; asm __volatile__ ( "mov %0, %%pc" : "=&r"(pc) ); return pc - 8 - (uintptr_t) find_offset; } But this technique requires that all data references be fixed up manually, so the filename() function in the above example would become: const char * filename(void) { static const char _filename[] __attribute__((section(".text"))) = "logfile"; return _filename + find_offset(); }

  • PHP Session Cookies fail with users changing IP

    - by Columbo
    Hello, I have a login script for a small application that works by storing session cookies and checking them on each page to make sure the user is logged in. One of the two users who uses the system keeps getting logged out randomly. This appears to be down to the session cookie that shows then authenticated no longer being present. After a lot of investigation the only thing I can see that is different about this user is that their IP address is changing (today it was changing every hour (their on Sky)). The only thing is the change of IP address has happened 5 times this morning and only once has the user been logged off. Has anyone had a similar issue? Are session cookies in someway tied to IP addresses? Any help or links much appreciated. Thanks C

  • jQuery Address - redirect after form submit

    - by Stian
    Hello all, I use jQuery and AJAX to load content from links and forms into a content div. In addition I use the Address plugin to enable the back button and refresh. On the server side I use Java and Spring MVC. Since I'm using jQuery Address and AJAX the only page that is directly loaded is "index.html". Everything else is loaded into a content div, and what page to load is specified in the hash, ie. "index.html#/users/add.html" will load "users/add.html". Now, "users/add.html" contains a form for creating a new user. When the form is submitted and everything went OK, the controller redirects to "users/index.html". The problem is that jQuery Address doesn't know about the redirect, so the url will remain "index.html#/users/add.html". And this is a problem when you refresh the page and then get sent back to the form, instead of the index page. Is there a way to fix this problem? Thanks, Stian

  • Event ID 9331 MSExchangeSA & Event ID 9335 MSExchangeSA

    - by George
    I get this two Exchange 2010 Global Address book related event IDs: Event ID 9331 MSExchangeSA OABGen encountered error 80004005 (internal ID 50101f1) accessing the public folder database while generating the offline address list for address list '/'. -\Default Offline Address List and Event ID 9335 MSExchangeSA OABGen encountered error 80004005 while cleaning the offline address list public folders under /o=xxxxx xxxx/cn=addrlists/cn=oabs/cn=Default Offline Address List. Please make sure the public folder database is mounted and replicas exist of the offline address list folders. No offline address lists have been generated. Please check the event log for more information. -\Default Offline Address List It is Exchange 2010 SP2 sitting on Windows 2008 enterprise edition. Essentially the issue is that the global address book is not being updated on Outlook clients. We are using Outlook 2007 and 2010. So far I have tried running the following command: Update-FileDistributionService -Identity ExchangeServer -Type "OAB" And I tried this solution as well: 1) Make sure the Microsoft Exchange System Attendant is running. It will be set to start automatically by default, but it doesn't. This is a known issue. Start this service manually. When running, you will not get an error when trying to update the GAL. 2) "Apply" any changes made to any address lists before the GAL will update Outlook properly. In Organization Configuration - Mailbox in EMC, view the properties of the Default Global Address Book in the Offline Address Book tab. In the properties window, select the Address Lists tab. This shows which address lists makes up the GAL. 3) Close the properties window and select the Address Lists tab in the Organization Configuration - Mailbox. Right-click each address list used by the Def GAL and click "Apply" (make sure the "Immediately" radio button is checked). 4) Last, go back to the Offline Address Book tab, right-click the GAL and select "Update". After a few send/receives in the Outlook clients, their Glogal Address List should update to show the latest changes. Neither one of those solutions helped. So I am not really sure what to do here. Also, I am aware of changing registry on each local computers, but it would be close to impossible as we have 8 offices in 3 different countries. Any suggestions? EDIT 7.XII.2012 @ 10.35 I forgot to mention that we did rebuild the address book and that didn't help.

  • INET_ATON() and INET_NTOA() in PHP?

    - by blerh
    I want to store IP addresses in my database, but I also need to use them throughout my application. I read about using INET_ATON() and INET_NTOA() in my MySQL queries to get a 32-bit unsigned integer out of an IP address, which is exactly what I want as it will make searching through the database faster than using char(15). The thing is, I can't find a function that does the same sort of thing in PHP. The only thing I came across is: http://php.net/manual/en/function.ip2long.php So I tested it: $ip = $_SERVER['REMOTE_ADDR']; echo ip2long($ip); And it outputs nothing. In the example they gave it seems to work, but then again I'm not exactly sure if ip2long() does the same thing as INET_ATON(). Does someone know a PHP function that will do this? Or even a completely new solution to storing an IP address in a database? Thanks.

  • Communicating with all network computers regardless of IP address

    - by Stephen Jennings
    I'm interested in finding a way to enumerate all accessible devices on the local network, regardless of their IP address. For example, in a 192.168.1.X network, if there is a computer with a 10.0.0.X IP address plugged into the network, I want to be able to detect that rogue computer and preferrably communicate with it as well. Both computers will be running this custom software. I realize that's a vague description, and a full solution to the problem would be lengthy, so I'm really looking for help finding the right direction to go in ("Look into using class XYZ and ABC in this manner") rather than a full implementation. The reason I want this is that our company ships imaged computers to thousands of customers, each of which have different network settings (most use the same IP scheme, but a large percentage do not, and most do not have DHCP enabled on their networks). Once the hardware arrives, we have a hard time getting it up on the network, especially if the IP scheme doesn't match, since there is no one technically oriented on-site. Ideally, I want to design some kind of console to be used from their main workstation which looks out on the network, finds all computers running our software, displays their current IP address, and allows you to change the IP. I know it's possible to do this because we sell a couple pieces of custom hardware which have exactly this capability (plug the hardware in anywhere and view it from another computer regardless of IP), but I'm hoping it's possible to do in .NET 2.0, but I'm open to using .NET 3.5 or P/Invoke if I have to.

  • Saving an IP adddress to DB

    - by Mark
    I want to save a user's IP address to my database just in case any legal issues come up and we need to track down who performed what action. Since I highly doubt I will ever actually need to use this data (well, maybe for counting unique hits or something) do you think I can just dump the REMOTE_ADDR into a field? If so, what should the length of that field be? 39 chars should fit an IPv6 address, no? I don't know if I'll ever get any of those, but just in case...

  • Creating a circually linked list in C#?

    - by Dexter
    What would be the best way to create a circually linked list in C#. Should I derive it from the LinkedList< T collection? I'm planning on creating a simple address book using this Linked List to store my contacts (it's gonna be a suck-y address book, but I don't care cause I'll be the only one to use it). I mainly just want to create the crucially linked list so that I can use it again in other projects. If you don't think the Linked List is the right way to go let me know which way would be better.

  • Cannot bind to IPv6 address

    - by ereOn
    I am facing a strange problem on my Ubuntu Karmic system. When I call getaddrinfo() with AI_PASSIVE and AF_UNSPEC, for an empty host and the UDP 12000 port to get a bindable address, I only get back one IPv4 result (0.0.0.0:12000 for instance). If I change my call and specify AF_INET6 instead of AF_UNSPEC, then getaddrinfo() returns "Name or service not known". Shouldn't I get [::]:12000 as a result ? The same thing happens if I set the host to ::1. When I call getaddrinfo() without AI_PASSIVE (to get a "connectable" address) for the host "localhost" and the UDP 12000 port, I first get [::1]:12000 then 127.0.0.1:12000. So apparently, my system is IPv6 ready (I can ping to both IPv4 and IPv6 addresses, as well as DNS resolution). But how is it that I can't get an IPv6 address to bind to with getaddrinfo() ? Do you guys have any idea about what could be wrong ? My OS is Ubuntu Karmic, fresh install without any networking tweaking. Thank you.

  • Change IP settings using C++

    - by Chris
    How do I change the IP settings of a Windows CE 6 box Programatically via C++? Functions for Windows might also work. I found that I can change the hostname via sethostname but couldn't find how to change IP address settings such as: IP Address DHCP Subnet Gateway DNS1 / DNS2 WINS1 / WINS2 Any advice / pointers would be great. Thanks. P.s. How would you get the box to update to those settings - is a refresh or the programming equivalent of ipconfig /renew required?

  • Uniquely identifying mobile devices over a network for webforms

    - by Eric
    I'm designing a system for mobile devices that can be assigned only to one job at a time. So I need to be able to know which mobile device is being used by accessing it's own unique static IP address or its device ID. I don't want to assign an ID myself for every machine that comes in which is why a static IP would work great. However, in trying to retrieve the client ip address I'm retrieving the wireless router's ip or some other ip which is not the mobile device's ip. I want to store that ip in a table and control which jobs are assigned to it. How can I accomplish this? I've tried the following but I'm getting the wireless ip: var hostEntry = Dns.GetHostEntry(Dns.GetHostName()); var ip = ( from addr in hostEntry.AddressList where addr.AddressFamily.ToString() == "InterNetwork" select addr.ToString() ).FirstOrDefault(); I'd rather not set a cookie if there exists a better alternative. TIA!

  • STUN-server using AWS

    - by Yrlec
    We are about to hire some consultants to help us set up an AWS-based server environment that will enable us to handle NAT Traversal for our P2P application. One important part of the NAT Traversal infrastructure is the STUN-server (http://en.wikipedia.org/wiki/STUN). They just told us that in order for the STUN-server to work you must have two public static IP-addresses pointing to the same server. To more specific they said this: It appears that you need 2 static IPs for each server for the STUN to work. Please note, these IPs have to be put into the configuration file, therefore, each time you restart the instance you have to make sure you either use the same IPs or you have to update configuration. As you plan to use AWS for your installation, please confirm that you can have 2 static IP for each server. Our question is if this is possible using AWS and if so, how? If not, do you know any other way to set up a STUN-server using AWS?

  • VPS IP redirects to website instead of the IP directory? CentOs 6

    - by Travis
    So before I started putting websites on my VPS, I could access the IP directly and it would access the html folder in the /var/www/ area. But ever since I placed websites on the VPS, I can no longer access that HTML folder, it goes to the first domain I have listed on the httpd.conf file. Is there a way I can make the IP its self look like a website in the httpd conf file? I tried to construct it like the other websites but httpd would stop working.
