• How do I deliver mail for wildcard addresses to a particular user/alias/program?

  - by David M

  I need to configure sendmail so that mail delivered for wildcard addresses is accepted for delivery and then delivered to a user, alias, or directly to a script. I can rewrite the envelope/headers any number of ways, but I don't know how to accept the wildcard address when it's provided in RCPT TO: Everything I've tried so far winds up with a 550 user unknown error. So here's a specific example: I want to be able to handle any address that consists of a series of digits followed by a dot followed by a word, then pipe that to a script. If the headers get rewritten, that's OK, but I need the envelope to contain the actual Delivered-To address. Here's the sort of SMTP session I need: 220 blah.foo.com ESMTP server ready; Thu, 22 Apr 2010 20:41:08 -0700 (PDT) HELO blort.foo.com 250 blah.foo.com Hello blort.foo.com [10.1.2.3], pleased to meet you MAIL FROM: <[email protected]> 250 2.1.0 <[email protected]>... Sender ok RCPT TO: <[email protected]> 250 2.1.5 <[email protected]>... Recipient ok I tried some stuff with regex maps, but I never got past 550 user unknown.

• Sending mail through local MTA while domain MX records point to Google Apps

  - by Assaf

  My domain's email is managed by Google Apps, so that domain users get Gmail and Calendar, etc. But I also want to be able to send applicative notifications to users outside the domain via email (e.g. "some commented on your post", and so on). However, if I try to send email through code I get blocked by Gmail after a few emails. I send marketing email through MailChimp, to minimize the risk of appearing as spam to my users (one-click unsubscribe, etc.). But I can't send applicative message in this way. I want to install a local MTA (my server runs Ubuntu), but I'm not sure what anti-spam measures I need to implement so that receiving MTAs don't think it's a spam server. What's stopping anyone from setting up a mail server and sending emails using my domain name? AFAIK it's the DNS records that show the MTA's address actually belongs to the domain. But my understanding of this is rather superficial, so someone please correct me if I'm wrong. But what sort of DNS configuration do I need to put in place so that I don't get blacklisted (assuming I don't actually spam anyone)? The MX records already point to Google, and I'd like to keep it this way. So do I just need to define an A record for my internal mail server? Should it show email as coming from a sub-domain, so as not to conflict with the bare domain being managed by google? Edit: Does the following SPF record make sense if I want email from my domain name to be sent by either google's servers or any server with a dns name ending with mydomain.com? "v=spf1 ptr mx:google.com mx:googlemail.com ~all" How should I set up reverse DNS for my server? If I have an A record that points mailsender.mydomain.com to my MTA's ip address, does it mean that reverse lookup will only allow emails sent from [email protected]?

• fedora, dhcpd fails to start

  - by soxs060389

  History: I got a tiny shiny plugserver which I want to plug to my ADSL router (or however you want to call it) on one end (eth0), and the other end (eth1) I want to run a dhcp server for my LAN. ATM I am stuck with getting LAN to work. OS is fedora 12. I configured my /etc/dhcp/dhcpd.conf like this: # # DHCP Server Configuration file. # see /usr/share/doc/dhcp*/dhcpd.conf.sample # see 'man 5 dhcpd.conf' # option domain-name "unknown.org"; option domain-name-servers 192.168.44.1; option subnet-mask 255.255.255.0; option broadcast-address 192.168.44.255; default-lease-time 86400; max-lease-time 172800; subnet 192.168.44.0 netmask 255.255.255.0 { host fedorabigbox { hardware ethernet 00:19:66:8E:61:74; fixed-address 192.168.44.21; } #host mobile #{ # hardware ethernet ***; # fixed-address 192.168.44.22; #} range 192.168.44.100 192.168.44.110; option routers 192.168.44.1; } # this is just dummy, as read many howtos, some suggesting to add a subnet blah netmask blah for each interface subnet 192.168.33.0 netmask 255.255.255.0 { range 192.168.33.100 192.168.33.110; option routers 192.168.33.1; } But the server fails to start when trying to start it via /etc/init.d/dhcpd start In general it would be nice if someone can point me to a in detail explanation of how network works, I am pretty new to this stuff. More concrete question: How to point the subnets to eth1 and the other to eth0, how can this be achieved? Does someone see any errors or flaws? Syntax should be correct, allready checked that with the dhcpd syntax check. Thanks for any help

• How to unblacklist an IP at Google?

  - by DJRayon

  I own a small business with two servers for webhosting. When setting up the primary (CentOS 5.5 + WHM, secondary is WHM DNS Only) server I kinda messed up the firewall, so the hackers could send stuff from my server. My primary IP is x.y.29.218. Anyway - I got blacklisted in several places, but now those blacklistings are gone. For a week or so, but Google still has my IP blacklisted. I handling serious damages because of that. Many clients want to switch from my hosting, etc. I've fixed the hole with CSF firewall SMTP_BLOCK option and enabled also the WHM SMTP TEAK Currently all I see from the Main Email View Mail Statistics (Errors section) in WHM is rows and rows of the following message removed-the-email-address-for-security R=lookuphost T=remote_smtp: SMTP error from remote mail server after end of data: host aspmx.l.google.com [a.b.39.27]: 550-5.7.1 [x.y.29.218 1] Our system has detected an unusual rate of\n550-5.7.1 unsolicited mail originating from your IP address.

I have one IP free. How can I configure Exim to send mail from that IP? My brain is like constantly blowing up because of this problem. Please someone, who has any knowledge how to deal with the current situation, please give me some kind of help - any help, suggestions, etc. I've tried everything I know, and I still don't know much, because this is the first time (I just started to webhost, etc) I deal with real physical servers not some kind of pre-setup VPS solution. Many - many thanks, whoever has time to offer some help.

• Website hosting from home - IIS6

  - by Paul

  I'm wanting to host a few websites from home, primarily because I'm using some BETA Microsoft software (.NET 4 and EF) and don't want to install it on my production server which is hosted at eukhost.com. Basically, I'm completely new to this sort of thing. So far, here is what I've done: Registered the domain name at namecheap.com (let's call it mydomain.com) Gone to "Nameserver Registration" in the panel and entered my IP address for the NS1 and NS2 records (let's say the IP is 0.0.0.0). Gone to "Domain Name Server Setup" and entered ns1.mydomain.com & ns2.mydomain.com Forwarded requests from port 80 to my internal IP (let's say 192.168.1.254) Created the website in IIS (I'm just testing with a single website so far, so have not created any host header values) Now, if I type in the IP address (http://0.0.0.0) I get the site as expected. However, if I enter http://www.mydomain.com I get an error saying "DNS Error - Cannot find server". I'm aware that there is a service from DynDNS that will automatically change the IP if I have a dynamic address, however my IP has remained static since I installed the ISP (since October) so I don't need this. Is there any way that I can get the DNS to work just by configuring IIS or something in Windows? I don't really want to have to pay for any 3rd party service. Thanks,

• Bridging my laptop's wireless and wired adaptors

  - by stacey.richards

  I would like to be able to connect a desktop computer that does not have a wireless adapter to my wireless network. I could just run a network cable from my ADSL/wireless router to the desktop computer but sometimes this is not practical. What I would really like to do is bridge my laptop's wireless and wired adapters in such a way that I can run a network cable from my laptop to a switch and another network cable from the switch to a desktop computer so that the desktop computer can access the Internet through my ADSL/wireless router via my latop: +--------------------+ |ADSL/wireless router| +--------------------+ | +-------------------------+ |laptop's wireless adaptor| | | |laptop's wired adaptor | +-------------------------+ | +------+ |switch| +------+ | +-----------------------+ |desktop's wired adapter| +-----------------------+ A bit of Googling suggests that I can do this by bridging my laptop's wireless and wired adapters. In Windows XP's Network Connections I select both the Local Area Connection and the Wireless Network Connection, right click and select Bridge Connections. From what I gather, this (layer 2?) bridge will examine the MAC address of traffic coming from the wireless network and pass it through to the wired network if it suspects that a network adapter with that MAC address may be on the wired side, and vice-versa. If this is the case, I would assume that when the desktop computer attempts to get an IP address from a DHCP server (which is running on the ADSL/wireless router), it would send a DHCP broadcast packet which would pass through the laptop's bridge to the router and the reply would return through the laptop's bridge back to the desktop. This doesn't happen. With some more Googling I find some instruction how this can be done with Linux. I reboot to Ubuntu 9.10 and type the following: sudo apt-get install bridge-utils sudo brctl addbr br0 sudo brctl addif br0 wlan0 sudo brctl addif br0 eth0 sudo ipconfig wlan0 0.0.0.0 sudo ipconfig eth0 0.0.0.0 Once again, the desktop cannot reach the ADSL/wireless router. I suspect that I'm missing some simple important step. Can anyone shed some light on this for me?

• Cluster Core Resource state of Exchange 2010 DAG

  - by Christoph

  I have two Exchange 2010 servers in a DAG and a witness server to implement mailbox resiliency. The two Exchange servers are in two subnets and the Windows failover cluster therefore has two IP address resources. I now that Exchange uses "core functionality" of Windows Server failover clustering, but it does not use all features. My setup also seems to work, but if I run the validation in the Windows Failover Cluster Manager, it complains about one of the IP address resources being offline. However, I cannot bring this resource online, because the server complains that "the specified cluster node is not the owner of the resource, or the node is not a possible owner of the resource". If I "Simulate failure of this resource", it becomes offline and the other IP becomes online. I have the vague idea that Exchange might use the state of the IP resource to identify the Primary Active Manager, but I am not sure. As it is obviously important that failover really works, I would like to be sure. Therefore, my question is: Is it normal that only one IP address resource in a Exchange 2010 DAG failover cluster is active at a time? If not, how do I bring both resources online at the same time given the error described above?

• ports only available from the outside network

  - by ChrisJ

  This is a counter-intuitive problem for me. I have a new Win 2003 server on a static IP address w.x.y.z. Tomcat 7, PostgreSQL 9.1, and Subversion are installed. All of it appears to be working fine from the server itself. We can also access the Tomcat manager, web applications, and run "svn ls svn://w.x.y.z/" from outside our network. However, when I try from another machine in the office, phpPgAdmin and svn cannot establish connections with the server. http://w.x.y.z:5432/phppgadmin cannot connect. The svn command from above returns: svn: E730061: Unable to connect to a repository at URL 'svn://w.x.y.z/' svn: E730061: Can't connect to host 'w.x.y.z': No connection could be made because the target machine actively refused it. Tomcat manager and the other web apps we have deployed work fine. Netstat -a from the server shows this: Proto Local Address Foreign Address State TCP SERVERNAME:3690 SERVERNAME:0 LISTENING TCP SERVERNAME:5432 SERVERNAME:0 LISTENING Windows Firewall was off, but just in case I also tried to enable it and open ports 3690 (svn) and 5432 (postgres). No change. I don't have access to the router/switch because it just doesn't work that way in Port-au-Prince and our sysadmin is on R&R. Is there anything that might be causing the problem from the server side?

• Connecting to my home router web interface from work

  - by Joe

  Hi, I'm trying to connect to my home router web interface from work. I use dyndns, because I don't have a static IP at home, and it works perfectly from any other place except my workplace (update: I made a mistake, see edit below). When trying to access the web interface from work I get a "500 Server Error" with the code: SERVER_RESPONSE_RESET. I'm not trying to use any protocols such as remote desktop, I'm only trying to access the web interface. I can access any other web page from my workplace with no problems, and I think my router web interface is like any other web page, isn't it? I thought maybe my work place proxy blocks addresses of services like dyndns, so I also applied another trick. Since I have a web page on my own domain (say www.mydomain.com) which I can access from work, I tried adding a CNAME to my domain which is linked to the dyndns address (router.mydomain.com). This way if anyone enters the address router.mydomain.com from anywhere, they reach my home router web interface, and there's no way of knowing it's a dyndns address (or is there?). However, it still doesn't work from my workplace (I get the same error message). Any ides? Edit: I'm sorry to say I made a mistake earlier. I used to be able to access my home router web interface from my old workplace, and I thought it was still possible since I don't recall making any configuration changes. However, after reading the replies, I went over to my old workplace and checked, and it doesn't work from there either. I'm very sorry for giving out wrong and misleading information about my problem. So to summarize: my problem is that I can't access my home router web interface from anywhere.

• How do I reference the value of a constructed environment variable in a loop?

  - by Rob Spieldenner

  What I'm trying to do is loop over environment variables. I have a number of installs that change and each install has 3 IPs to push files to and run scripts on, and I want to automate this as much as possible (so that I only have to modify a file that I'll source with the environment variables). The following is a simplified version that once I figure out I can solve my problem. So given in my.props: COUNT=2 A_0=foo B_0=bar A_1=fizz B_1=buzz I want to fill in the for loop in the following script #!/bin/bash . <path>/my.props for ((i=0; i < COUNT; i++)) do <script here> done So that I can get the values from the environment variables. Like the following(but that actually work): echo $A_$i $B_$i or A=A_$i B=B_$i echo $A $B returns foo bar then fizz buzz

• Ubuntu 12.04 suddenly cannot connect to WPA2/WPA Personal protected connection. Windows 7 can

  - by d4ryl3

  I have a laptop with Windows 7 and Ubuntu 12.04. I have a Cisco E1200 and when I set it up, it created 2 SSIDs. Let's name them: MyConnection (WPA/WPA2 personal), and MyConnection-Guest (no authentication, guest password entered via web browser). I had no problem connecting to MyConnection before, either in Windows 7 and Ubuntu. But now, I can't access MyConnection on Ubuntu. It just says "connecting..." then disconnects after a while. But I'm able to access the internet (on Ubuntu) when I connect to MyConnection-Guest. MAC filtering is off (even if it's on its MAC address is in the white list). Any idea why I'm unable to connect to MyConnection in Ubuntu? Thanks. Update: My Ubuntu installation can connect to ANY WiFi connection (WPA/WEP/no auth), except for MyConnection.

• Excel - graphing mean and standard deviation

  - by joe_shmoe

  Hi all, I have measurements for multiple devices, and have their mean and sd values. I would like to produce a chart that would show these values, and I think the best would be if I could have something that looks like a bar chart(-ish) - the device names in x axis, values in y axis, and for each device to have a 'floating' bar that would represent values (mean - sd :: mean + sd), and some marker in the middle to show the actual mean value. is it doable? or would you suggest some other chart? Thanks a lot

• Solaris 10 invalid ARP requests from 0.0.0.0? Link up/down every hour or 2

  - by JWD

  The guys at the data center where I'm hosting a server running Solaris 10 are telling me that my server is making a lot of invalid arp requests. This is an example of a portion of what was sent to me from the logs (with Mac addresses and IP addresses changed). [mymacaddress]/0.0.0.0/0000.0000.0000/[myipaddress]/[Datestamp]) It's being logged every hour. I don't see anything in the arp tables (arp -a) or routing tables (netstat -r) and I don't see anything relating to 0.0.0.0 when snoping the arp requests. The only place I see any reference to 0.0.0.0 is if I do netstat -a for the SCTP SCTP: Local Address Remote Address Swind Send-Q Rwind Recv-Q StrsI/O State ------------------------------- ------------------------------- ------ ------ ------ ------ ------- ----------- 0.0.0.0 0.0.0.0 0 0 102400 0 32/32 CLOSED But not really sure what that means. Doesn't seem like I can disable SCTP. There are some tunable SCTP parameters but it's not something I'm familiar with. Do I have to add changes to /etc/system? Looks like sctp_heartbeat_interval might be what I need to change? If it makes any difference, I have a few solaris zones running on this server, each with their own IP address on a virtual interface. eth0:0, eth0:1, etc. Does anyone have any idea what might be causing this and how to stop it? I think the switch I'm connected to doesn't like it and momentarily drops the connection. Is there anyway to at least block those requests using ipfilter or something else? Update: This was happening more frequently but now it seems to be happening roughly every hour or every two hours. It's not consistent. I tried setting setting the link speed and duplex to match the switch port and that seemed to make it stop happening for a few hours but then it started again.

• How to Launch Spotlight from the Terminal

  - by Jack7890

  I used this tip top hide my menu bar in a bunch of applications, which is a great way to get more free screen space. The one downside is that (for inexplicable reasons) it disables Spotlight when I'm in those applications--e.g. even if I hover over the menu bar to make it appear, clicking on the Spotlight icon does nothing. I have a plan to work around this: I'd like to launch Spotlight using QuicKeys, which lets you run terminal commands using keyboard shortcuts. But to do that, I need to know how to launch Spotlight with a terminal command. Does anyone know how to do this? I'm on OS X 10.6.

• Questions about Domains and DNS

  - by ShoX

  Hi, I am totally new to the DNS and server hosting world and not quite sure what I need. I want to get a domain, forward it to my own server, so that the user sees example.com in the url bar and example.com/foo/bar will work. Depending on what subdomain it is, it should do different things (another base-directory at webserver, ftp, etc). Also my email should be able to be sent to and received by that server. What irritates me, is the fact, that in the A-record I can only list IP-addresses and no ports. So do I have to set up a nameserver on my own server? Or do I accomplish this via vhosts on my webserver? I would appreciate any help or link to a tutorial. I know how DNS works, know some basic apache-stuff, etc... so no need to explain that. Thanks

• Customize side panel in Internet Explorer 9/Windows 7

  - by Kari

  I use Internet Explorer 9 with all the horizontal toolbars except the tab bar invisible to maximize vertical space. I have plenty of room at the side so I have the Favorites/Feeds/History panel open, usually on Favorites to replace the Favorites bar. I'd like to customize the shortcuts in this panel to display as large icons, similar to when you set the display in Windows Explorer to Large Icons and, long shot... change the backround color. The side panel does appear to be just a Windows Explorer window but it seems immune to any kind of tampering or customization, mainly because right clicking is disabled on the empty space. Changing browsers is not going to happen but can someone help out here?

• E-mail duplication problem

  - by Gavin Osborn

  I have taken out a hosting agreement with a well respected hosting provider for a couple of internet facing servers. We have deployed several applications to these servers which send various e-mails back to us for reporting purposes. Context: Each server runs Windows Server 2003 R2 with the IIS 6.0 SMTP service installed. Each application is configured to use the local instance of IIS to send e-mails. The external IP address of each server is mapped to a particular domain eg: server1.mydomain.com server2.mydomain.com These e-mails are sent from a company domain name and not the domain name of the hosted servers (eg: [email protected]) Symptoms: A small number (<1%) of e-mails sent from these applications appear to be duplicated. These are exact duplicate in terms of both content and message headers. The Fix: I contacted my hosting provider and they told me this was a common problem & instructed me to: Change the HELO response of your mail server service to a FQDN (server1.mydomain.com && server2.mydomain.com) Create a DNS A record that resolves the FQDN of your mail server to the primary IP address of your sending mail server. Create a PTR record that resolves your primary IP address back to your mail server's FQDN In the sending domain's (mycompanydomain.com) DNS zone file, add the appropriate SPF record for your hosted servers. eg: v=spf1 a mx include:mydomain -all The Problem Continues: I made all of the changes as prescribed above, I was a little hesitant because these steps seemed to suggest they were more for stopping your messages getting blocked than they were for stopping them from being duplicated - but I am certainly no expert in these matters. It has been 5 days since I applied this fix and the problem still persists. I am certain that these problems are not a bug in the software because they are 4 different applications installed on 2 different servers, all of whom are exhibiting this strange behaviour. This behaviour has also not been seen in our UAT environment. Were my hosts correct to suggest this fix? If not, does anyone know what could be the cause of this problem? Many Thanks

• Exchange 2010 sends out spam.

  - by Magnus Gladh

  Hi. I have an Exchange Server 2010, that uses a smart host to send out mails. A day ago the owner of smart host contact us and told us that we send out spam. I have try different open relay test on the net and all of them come back saying that this server is secured and can not be used as relay server. But I can see in my Exchange Queue Viewer that it keeps coming in new messages. Here is an example of how it looks. Identity: mailserver\3874\13128 Subject: Olevererbart:: [email protected] Pfizer -75% now Internet Message ID: <[email protected]> From Address: <> Status: Ready Size (KB): 6 Message Source Name: DSN Source IP: 255.255.255.255 SCL: -1 Date Received: 2010-12-09 21:46:22 Expiration Time: 2010-12-11 21:46:22 Last Error: Queue ID: mailserver\3874 Recipients: [email protected] How can I secure our exchange server more, to stop this from happening? Could I have got an virus that hooks up to our exchange server and send mail throw that? As I can see the From Address is always <, is there someway that I can stop sending mails that don't have a from address that I describe? Pleas help

• How the heck is http://to./ a valid domain name?

  - by Chris

  Apparently it's a URL shortener. It resolves just fine in Chrome and Firefox. How is this a valid top-level domain? Update: for the people saying it's browser shenanigans, why is it that: http://com./ does not take me to: http://www.com/? And, do browsers ever send you a response from some place other than what's actually up in the address bar? Aside from framesets and things like that, I thought browsers tried really hard to send you content only from the site in the address bar, to help guard against phishing.

• Creating IIS Rewrite Rules

  - by Tom Bell

  I'm having a hard time converting old .htaccess rewrite rules to new IIS ones so I was wondering if anyone could point me in the right direction. Below are some example URLs I would like rewriting. http://example.org.uk/about/ Rewrites to http://example.org.uk/about/about.html ----------- http://example.org.uk/blog/events/ Rewrites to http://example.org.uk/blog/events.html ----------- http://example.org.uk/blog/2010/11/foo-bar Rewrites to http://example.org.uk/blog/2010/11/foo-bar.html The directories and file names are generic and could be anything. Any help would be greatly appreciated.

• Unable to access network resources through VPN

  - by fbueckert

  I'm currently attempting to connect one of our computers in the office to a client VPN. My development machine is running Windows 7, and can connect and see resources just fine. The problem computer is running Windows XP. They're both within the same network. Using the same credentials at both computers, the VPN connection (using the built in Windows network connections) works just fine. So far, so good. An IP address is assigned, and comparing both machines shows they're still in the same subnet. The problem is that the XP machine cannot see ANY of the computers in the client network. I tried a tracert to a target machine on the Windows 7 box, and the first item that comes up is the .0 address. Pinging it gives responses. Trying it on the Windows XP machine, however, comes up with just timeouts. Trying to trace to www.google.com allows the address to resolve (probably part of the cached resolutions), but results in just timeouts. I double-checked to make sure that the Windows firewall was not on, and trying to open the settings brings up a notification that the firewall service wasn't running, which leads me to believe that it's definitely not on. From my best guess, I've managed to connect the XP machine to a black hole of some sort. There's obviously something strange going on, but I'm not sure where I should be looking.
