  • Mod_rewrite is ignoring the extension of a file

    - by ngl5000
    This is my entire mod_rewrite condition: <IfModule mod_rewrite.c> <Directory /var/www/> Options FollowSymLinks -Multiviews AllowOverride None Order allow,deny allow from all RewriteEngine On # force www. (also does the IP thing) RewriteCond %{HTTPS} !=on RewriteCond %{HTTP_HOST} !^mysite\.com [NC] RewriteRule ^(.*)$ http://mysite.com/$1 [R=301,L] RewriteCond %{REQUEST_URI} ^system.* RewriteRule ^(.*)$ /index.php?/$1 [L] RewriteCond %{REQUEST_URI} ^application.* RewriteRule ^(.*)$ /index.php?/$1 [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.+)\.(\d+)\.(js|css|png|jpg|gif)$ $1.$3 [L] RewriteCond %{THE_REQUEST} /index\.(php|html) RewriteRule (.*)index\.(php|html)(.*)$ /$1$3 [r=301,L] RewriteCond %{REQUEST_URI} !^(/index\.php|/assets|/robots\.txt|/sitemap\.xml|/favicon\.ico) RewriteRule ^(.*)$ /index.php/$1 [L] # Block access to "hidden" directories or files whose names begin with a period. This # includes directories used by version control systems such as Subversion or Git. RewriteCond %{SCRIPT_FILENAME} -d [OR] RewriteCond %{SCRIPT_FILENAME} -f RewriteRule "(^|/)\." - [F] </Directory> </IfModule> It is suppose to allow only access to mysite.com(/index.php|/assets|/robots.txt|/sitemap.xml|/favicon.ico) The error was noticed with: mysite.com/sitemap vs mysite.com/sitemap.xml Both of these addresses are resolving to the xml file while the first url should be resolving to mysite.com/index.php/sitemap * For some reason mod_rewrite is completely ignoring the lack of an extension. It sounded like a Multiviews problem to me so I disabled Multiviews and it is still going on. ***And then a different rule will eventually take the index.php out, I am having another problem with an extra '/' being left behind when this happens. This httpd file is setting up for my codeigniter php framework

  • Understanding mail failure notices, 554

    - by goran
    I'd like to confirm the meaining of a mail failure notice. Here's the message Hi. This is the qmail-send program at mydomain.com I'm afraid I wasn't able to deliver your message to the following addresses. This is a permanent error; I've given up. Sorry it didn't work out. <[email protected]>: 1.2.3.4 does not like recipient. Remote host said: 554 <[email protected]>: Relay access denied Giving up on 1.2.3.4 The way I understand this is, that 1.2.3.4 is not setup to receive mail for this domain. dig domain.com MX shows ;; ANSWER SECTION: domain.com. 6245 IN MX 10 mail.domain.com. domain.com. 6245 IN MX 20 mx.anotherdomain.com. (1.2.3.4 is mx.anotherdomain.com.). The puzzling part is that I have reports that messages sent from gmail get delivered to this address. P.S. Is this a proper question for serverfault?

  • Emails sent to outlook.com not being delivered

    - by imukcedup
    I'm having an issue that is a little strange. I have a cPanel webserver that I own and have root. I was testing out emailing and noticed some issues. When I send an email to outlook.com address the email sends ok but nothing is recieved at the outlook mailbox. I also dont get an 'email delivery failure notification' in any mailbox. 2014-06-12 09:53:47 SMTP connection from [127.0.0.1]:45334 (TCP/IP connection count = 1) 2014-06-12 09:53:47 1Wv5Rr-0003rA-2K <= [email protected] H=localhost (ourdomain.com) [127.0.0.1]:45334 P=esmtpa A=dovecot_login:joe S=667 [email protected] T="This is a test message" for [email protected] 2014-06-12 09:53:47 SMTP connection from localhost (ourdomain.com) [127.0.0.1]:45334 closed by QUIT 2014-06-12 09:53:50 cwd=/var/spool/MailScanner/incoming/1029481 5 args: /usr/sbin/exim -C /etc/exim_outgoing.conf -Mc 1Wv5Rr-0003rA-2K 2014-06-12 09:53:50 1Wv5Rr-0003rA-2K SMTP connection outbound 1402581230 1Wv5Rr-0003rA-2K ourdomain.com [email protected] 2014-06-12 09:53:50 1Wv5Rr-0003rA-2K => Test Account <[email protected]> R=archive_outgoing_email T=archiver_outgoing 2014-06-12 09:53:52 1Wv5Rr-0003rA-2K => [email protected] R=dkim_lookuphost T=dkim_remote_smtp H=mx1.hotmail.com [65.54.188.110] X=UNKNOWN:AES128-SHA256:128 C="250 <[email protected]> Queued mail for delivery" 2014-06-12 09:53:52 1Wv5Rr-0003rA-2K Completed I have checked the outlook.com's spam folders and its not in there either. This is a new IP address allocation from our ISP and there was a block on gmail addresses, so we know it was used for spam. But with gmail we got a notifaction of failure and I know outlook/microsoft also send out notification. Does anyone know what could be happening here? Thanks

  • Advance DNS - Redirecting Emails to new webhost

    - by Martin
    I am not to sure if this question belongs here but I will surely find out soon enough. I have two web hosts (Not sure why it has been setup this way but it has). I do not want to use the original web host to handle the emails as the Data that we get from them is 500 mb which is already full with hosting the website. The second web host has an unlimited data plan and was created so we could use this host for the email accounts. Now the problem is I have reset the Advance DNS Zone records on both accounts and I am not sure what they were before. (Silly me should have taken a backup of how it was setup before hand I know) Emails were working before and going to the second hosts server now they are going to the first host but it has no email addresses setup for use so all emails are bouncing saying that the address does not exist. Host 1 IP: 192.185.96.110 Host 2 IP: 27.54.88.66 So far I have changed the Advanced DNS Zone record on Host 1 with the following: A Record: mail.australisinstitute.qld.edu.au - 27.54.88.66 I have not made any changes on Host 2 and both hosts have the default MX Records. If I need to provide any more information I can but I just hope someone can decipher what I have said haha. Cheers in advance!

  • Can't get simple Apache VHost up and running

    - by TK Kocheran
    Unfortunately, I can't seem to get a simple Apache VHost online. I used to simply have one VHost which bound to all: <VirtualHost *:80>, but this isn't appropriate for security anymore. I need to have one VHost for localhost requests (ie my dev server) and one for incoming requests via my domain name. Here's my new VHost: NameVirtualHost domain1.com <VirtualHost domain1.com:80> DocumentRoot /var/www ServerName domain1.com </VirtualHost> <VirtualHost domain2.com:80> DocumentRoot /var/www ServerName domain2.com </VirtualHost> After I restart my server, I see the following errors in my log: [Wed Feb 16 11:26:36 2011] [error] [client ####.###.###.###] File does not exist: /htdocs [Wed Feb 16 11:26:36 2011] [error] [client ####.###.###.###] File does not exist: /htdocs What am I doing wrong?

  • Postfix Whitelist before recipient restrictions

    - by GruffTech
    Alright. Some background. We have an anti-spam cluster trucking about 2-3 million emails per day, blocking somewhere in the range of 99% of spam email from our end users. The underlying SMTP server is Postfix 2.2.10. The "Frontline defense" before mail gets carted off to SpamAssassin/ClamAV/ ect ect, is attached below. ...basic config.... smtpd_recipient_restrictions = reject_unauth_destination, reject_rbl_client b.barracudacentral.org, reject_rbl_client cbl.abuseat.org, reject_rbl_client bl.mailspike.net, check_policy_service unix:postgrey/socket ...more basic config.... As you can see, standard RBL services from various companies, as well as a Postgrey service. The problem is, I have one client (out of thousands) who is very upset that we blocked an important email of theirs. It was sent through a russian freemailer who was currently blocked in two of our three RBL servers. I explained the situation to them, however they are insisting we do not block any of their emails. So i need a method of whitelisting ANY email that comes to domain.com, however i need it to take place before any of the recipient restrictions, they want no RBL or postgrey blocking at all. I've done a bit of research myself, http://www.howtoforge.com/how-to-whitelist-hosts-ip-addresses-in-postfix seemed to be a good guide at first, almost fixing my problem, But i want it to accept based on TO address, not originating server.

  • Web Server Routing Based On Location

    - by Eric
    I have a website that has users from both Hong Kong and Australia. Unfortunately, since the server is located in Australia, users from Hong Kong are going to suffer latency problems. Traffic has to go through US before travelling back to Australia. So I've setup a server in Hong Kong as well, and users using the .hk TLD are going to be redirected to the Hong Kong web server. It shares the same database server with the Australian server but due to aggressive SQL query caching, impact on performance from latency from SQL queries are negligible. But for users accustomed to the Hong Kong website but have since traveled to Australia, they suffer from additional latency because they go to the .hk site which redirects to the HK server even when they're in Australia. The website is targeted at international students from Hong Kong so this is an significant issue for me. Instead of redirecting users to the closest web server based on the TLD, how do I redirect users based on their location? Currently I am using nginx, postgres and Django. Say I know how to estimate users' location based on users' IP addresses, what is my next step? At what level would I work on? What topic should I read up?

  • Windows 8 - no internet connetction to some hosts while VPN is active

    - by HTD
    I use VPN to access the servers at work. When VPN is used, all network traffic to the Internet passes through my company network. It worked without any problems on Windows 7, now on Windows 8 some sites suddenly became inaccessible. Please note - I don't try to connect them over RDP, they are public Internet addresses, outside company network. They are inaccessible using any protocol. Ping returns "General failure.". I know it could be a misconfiguration on my company's server side, but it's very strange, since the same VPN connection used on Windows 7 works properly. What's wrong? Is it a Windows 8 bug, or is there something I could do on my company servers to make VPN work as expected with Windows 8? My company network works on Windows Server 2008 R2 and uses Microsoft TMG firewall. I couldn't find any rules blocking the traffic to mentioned sites, all network traffic for VPN users are passed through for all IPs and protocols. Any clues? UDPATE: Important - one whole day it worked. I hibernated and restarted the computer, connected and disconnected VPN - nothing could break my connection. Today it broke again, and restarting Windows didn't help. And now the solution: route add -p 0.0.0.0 MASK 255.255.255.255 192.168.1.1 Oh, OK, I know what it did, added my default gateway to routing table. But it still didn't work sometimes. So I removed my main network gateway route with: route delete -p 0.0.0.0 MASK 0.0.0.0 192.168.0.1 And added modified with: route add -p 0.0.0.0 MASK 255.255.255.255 192.168.0.1 And it works. Now. But I don't trust this. I don't know what really happened.

  • IIS7 binding to subdomain causing authentication errors (TFS 2010)

    - by Tommy Jakobsen
    I'm trying to bind a IIS web site (Team Foundation Services 2010) to a subdomain, which is causing authentication errors. First I'll explain what I've done to set it up. This is the fist time I do this, so please correct me if I'm wrong. The web server is a stand-alone Windows Server 2008 R2 x64, running IIS7 with .NET Framework 4. I have the following A-records, pointing to my server: server.mydomain.com *.server.mydomain.com So all subdomains of server.mydomain.com points to the server. In IIS7 I have a web site (TFS 2010) on port 8080, with a virtual directory (named tfs) that is using Windows Authentication. I have one binding on the web site pointing to all unassigned IP addresses, port 8080 and having a host name of tfs.server.mydomain.com. Now, shouldn't I be able to access the virtual directory through: http://tfs.server.mydomain.com/tfs That is not working. However, I can access it through: http://tfs.server.mydomain.com:8080/tfs But, it won't let me authenticate using a Windows account (Server\Username). A windows account that I can authenticate with, when accessing the site through http://localhost:8080/tfs. What am I missing here?

  • Cisco IOS policy route for router originated VPN traffic

    - by Paul
    We have a Cisco IOS router with two DSL connections. One of them is intended for general traffic (ADSL), the other for VPN links (BDSL) and various other traffic. So the default route is the ADSL link, and we have a combination of static routes for the VPN traffic, and policy routes for other traffic types that should go out the BDSL link. For site to site traffic, this is fine, we just static route the public IPs and remote networks out of the BDSL line. The policy based routing works fine for any internal traffic that matches an ACL. The problem is now that there are remote VPN sites originating from dynamic addresses, so we cannot use static routes. The replies to incoming ISAKMP requests are following the default route out of the ADSL (despite there being no crypto map on that interface). I want to route the outgoing VPN traffic out of the BDSL. I have tried adding udp/500 and esp to and from the route-map acl that pushes traffic out of the BDSL line, but it doesn't match, presumably because the route-map happen earlier than the IPSec stuff. Any ideas how I can do this? IOS ver: 12.4.13T.

  • DNS, subdomain, and IPv6 -- possible to add subdomain.example.com NS record to an IPv6 host?

    - by mpbloch
    example.com is listed with a registrar -- specifically, answerable.com. I want to host a subdomain in-house, specifically home.example.com. I am using an ipv6 gateway, specifically gogo6, to have a public IPv6 address. The IP address looks like 2001:xxxx:xx47. Then http://[2001:xxxx:xx47] goes to my test site (an instance of IIS7). I can add a quad-A record for my primary site -- home.example.com AAAA 2001:xxxx:xx47. Then http//home.example.com loads correctly. Must I add an A or quad-A record for all sub.home.example.com to my answerable.com DNS manager for example.com? Or can I delegate DNS queries to *.home.example.com to the machine at [2001:xxxx:xx47]? I have tried to add a AAAA record for tunnel.example.com to [2001:xxxx:xx47], and then add an NS entry for home.example.com to tunnel.example.com, but browsing then results in "DNS lookup error" from my browser. Is this a configurable scenario? Can DNS for subdomain only be delegated to IPv4 addresses?

  • Outlook Shared Address book and contact not displaying

    - by user224061
    We have a shared Exchange addressbook with distribution email groups. When someone connects to the shared addressbook, composes an email to a group, the email distribution list is empty, then the distribution list is expanded. In troubleshooting, I noticed that when we expand the distribution list to view the recipients, most of the recipients are missing and only semicolons appear. CLICK HERE FOR IMAGE Further troubleshooting, I notice that when I open the distribution list with my Outlook client and click on the Update Now icon, and then go to create the email then when I expand the group the email addresses now appear. CLICK HERE FOR IMAGE Now, my Outlook profile is a cached profile. The shared contact list that I pulled the distribution list from is an online/non-cached shared contact list. What I also found is that if I switched my Outlook client to be online only(not cached) the share address book lists appear properly when expanded. Is there any way to make this list appear correctly without having to click on update now for each and every distribution list in the shared contacts list we have on the server? I would really prefer that every time one wants to use this shared contact list, they do not have o click the update not button or switch from cached mode to make this work. T.I.A

  • PGB Multipath & return routes

    - by Dennis van der Stelt
    I'm probably a complete n00b concerning serverfault related questions, but our IT department makes a bold statement I wish to verify. I've searched the internet, but can find nothing related to my question, so I come here. We have Threat Management Gateway 2010 and we used to just route the request to IIS and it contained the ip address so we could see where it was coming from. But now they turned on "Requests apear to come the TMG server" so ip addresses aren't forwarded anymore. Every request has the ip of the TMG server. Now the idea behind this is that because of multipath bgp routes, the incoming request goes over RouteA, but the acknowledgement messages could return over RouteB. The claim is that because the request doesn't come from the first known source, our proxy, but instead from IIS, some smart routers at the visitor of our websites don't recognize the acknowledgement message and filter it out. In other words, the response never arrives. Again, this is the claim. But I cannot find ANY resources on the internet that support this claim. I do read about pgb multipath, but more in the case that there are alternative routes when the fastest route fails for some reason. So is the claim completely bogus or is there (some) truth to it? Can someone explain or point me to resources? Thanks in advance!

  • problem with .Net xml importnode in powershell

    - by Trondh
    Hi, Im trying to construct a powershell script that uses some XML. I have a XML document where I try to add some values with email addresses. The finished xml document should have this format: (I'm only showing the relevant part of the xml here) <emailAddresses> <value>[email protected]</value> <value>[email protected]</value> <value>[email protected]</value> </emailAddresses> SO, in powershell I try to do this as a test, which fails: $newNumber = [xml] '<value>555-1215</value>' $newNode = $Request2.ImportNode($newNumber.value, $true) $emailnode.AppendChild($newNode) After some reading, I have figured out that if I do this, it suceeds: $newNumber = [xml] '<value name="flubber">555-1215</value>' $newNode = $Request2.ImportNode($newNumber.value, $true) $emailnode.AppendChild($newNode) So, I am stuck. I'm starting to wonder if I should use another function instead of importnode when I have several keys with the same name but different values. As you guys probably have figured out by now, i'm not an expert in xml. ANy help appreciated!

    - by Tom
    I'm trying to setup Apache(2.2.3) to run two websites with SSL using both different domains and IP addresses. Both websites run fine on port 80 but when I tried to enable SSL for website2 I get a ssl_error_bad_cert_domain error; website2 picks up the SSL cert for website1. Here is my setup in httpd.conf: # Website1 NameVirtualHost 192.168.10.1:80 <VirtualHost 192.168.10.1:80> DocumentRoot /var/www/html ServerName www.website1.org </VirtualHost> NameVirtualHost 192.168.10.1:443 <VirtualHost 192.168.10.1:443> SSLEngine On SSLCertificateFile conf/ssl/website1.cer SSLCertificateKeyFile conf/ssl/website1.key </VirtualHost> # Website2 NameVirtualHost 192.168.10.2:80 <VirtualHost 192.168.10.2:80> DocumentRoot /var/www/html/chart ServerName www.website2.org </VirtualHost> NameVirtualHost 192.168.10.2:443 <VirtualHost 192.168.10.2:443> SSLEngine On SSLCertificateFile conf/ssl/website2.cer SSLCertificateKeyFile conf/ssl/website2.key </VirtualHost> Update: In answer to Shane (this wouldn't fit in comment box) here is the output from apachectl -S: VirtualHost configuration: 192.168.10.2:80 is a NameVirtualHost default server www.website2.org (/etc/httpd/conf/httpd.conf:1033) port 80 namevhost www.website2.org (/etc/httpd/conf/httpd.conf:1033) 192.168.10.2:443 is a NameVirtualHost default server bogus_host_without_reverse_dns (/etc/httpd/conf/httpd.conf:1040) port 443 namevhost bogus_host_without_reverse_dns (/etc/httpd/conf/httpd.conf:1040) 192.168.10.1:80 is a NameVirtualHost default server www.website1.org (/etc/httpd/conf/httpd.conf:1017) port 80 namevhost www.website1.org (/etc/httpd/conf/httpd.conf:1017) 192.168.10.1:443 is a NameVirtualHost default server bogus_host_without_reverse_dns (/etc/httpd/conf/httpd.conf:1024) port 443 namevhost bogus_host_without_reverse_dns (/etc/httpd/conf/httpd.conf:1024) wildcard NameVirtualHosts and _default_ servers: _default_:443 192.168.10.1 (/etc/httpd/conf.d/ssl.conf:81) Syntax OK

  • Disable IPv6 on Debian VPS (Virtuozzo!)

    - by chris_l
    I have a Debian Lenny VPS, that's running virtualized by Parallels/Virtuozzo. Currently, the network interface doesn't have an IPv6 address - and that's good, because I don't have an ip6tables configuration. But I assume, that I could wake up one day, and ifconfig will show me an ipv6 address for the interface - because I have no control over the kernel or its modules - they're under the control of the hosting company. That would leave the server completely vulnerable to attacks from IPv6 addresses. What would be the best way to disable IPv6 (for the interface or maybe for the entire host)? Usually I would simply disable the kernel module, but that's not possible in this case. Update Maybe I should add, that I can use iptables and everything normally (I'm root on the VPS), but I can't make changes to the kernel or load kernel modules because of the way Virtuozzo works (shared kernel). lsmod always returns nothing. I can't call ip6tables -L (it says that I need to insmod, or that the kernel would have to be upgraded). I don't think, that changes to /etc/modprobe.d/aliases would have any effect, or do they? Networking Config? I thought, that maybe I can turn IPv6 off from /etc/network/... Is that possible? I just see, that they've set up avahi, so I should probably change the setting use-ipv6=yes to "no" in /etc/avahi/avahi.conf (?) Has anybody already tried this solution, and can I rely on it? I don't know too much about avahi. Would it actually have any effect? Or could it even bring my entire interface down, once IPv6 is enabled by the kernel?

  • Setting up DNS using VirtualMin/WebMin

    - by Nyxynyx
    I am moving from a cPanel server to one where I've installed VirtualMin. The LAMP stack and the website files have been setup properly and I can access the website by its IP address. Problem: Now its time to point my domain mydomain.com to my new server. After reading many sites describing setting up bind and master zones, I am pretty confused as to what to do, especially coming from a cPanel server where its really simple to set this up. Attempt Tried to register my nameservers ns1.mydomain.com and ns2.mydomain.com at my domain registrar, but I am missing the IPs I need to point these nameservers to. Should I set ns1.mydomain.com to the IP addres of my web server, and not register ns2.mydomain.com? When specifying the DNS for mydomain.com, the first one I've set it to ns1.apadment.com. On the manager/admin page of my webhost provider, I am given the option to create a secondary slave DNS, which I assigned to the IP address of my server. Though I am not sure how the slave DNS will copy the info from my web server? I have assigned this secondary DNS ns.hostprovider.com as the second DNS for mydomain.com I tried creating a Virtual Server under Virtualmin, but it seems to mess up Apache's DocumentRoot for the site by creating and enabling a new vhost file that ends with .conf. I edited the .conf file to point DocumentRoot back to where its supposed to be /var/www/mydomain instead of /user/mydomain.com I believe the next step is to setup the zone. Virtualmin has already created a Master Zone with 8 different addresses (www.mydomain.com, ftp.mydomain.com...). Under Nameservers, there are already 2 records. One is the hostname (random name given by hostprovider, ns12345.ip123-123.net), the other is the secondary slave DNS provided by the host provider. Does having BIND running on my web server makes the server the master DNS? Thank you!

  • Why should one have a secondary DNS server?

    - by Sam Levin
    I'm very confused. I basically understand how DNS works. Here's an example that helps illustrate what I'm having trouble understanding. Right now, I run a small web-server. I use my provider's DNS manager, so I don't have a DNS server hosted on the machine. Let's say for a second, that I don't use my host's DNS, and I decide to set up a DNS server on my server. Hypothetical scenario: my server (entire) server goes down - DNS included. Why do I need backup DNS? If the server is down, who cares if the DNS server is down too, considering that even if I had DNS up (it wasn't on the crashed server), it wouldn't be able to forward requests anyway since the server would be down? Is the point of having secondary DNS, to be able to change the IP addresses that your DNS server points to, so if your webserver was down, you could redirect traffic to a backup? How would you switch to the secondary provider, in the event that your main DNS provider becomes unavailable? Is a backup DNS system basically up all the time? How is it configured? Is it just an exact clone of the DNS server you would have on your server? Do they run simultaneously? Hopefully someone can see what I'm hung up on, and provide some guidance. Thanks

  • Varnish configuration, NamevirtualHosts, and IP Forwarding

    - by Brent
    I currently have a bunch of NameVirtualHost based websites, load balanced between 3 apache2 servers using ldirectord. I would like to insert varnish as a reverse-web-proxy between ldirectord and apache in the following way: a request comes in to ldirectord it is then load balanced between the 3 apache2 servers and varnish, with a weight of 1 for the webservers, and 99 for varnish (so if varnish is rebooted, the webservers will take over seamlessly) varnish will then load balance its requests between my apache2 servers. However, the varnish part is not working. I wonder whether this has to do with the fact that my apache servers use x.x.x.x:80 for their NameVirtualHosts, instead of *:80? (they have to do this, since each server hosts multiple IP addresses) Or perhaps it has to do with the need for IP Forwarding to be set up on the varnish server? (I did echo 1 /proc/sys/net/ipv4/ip_forward on this server, is that sufficient?) How can I debug this problem? ldirectord doesn't produce logs of what it does with each request (and if it did, I would be overwhelmed with information since I'm serving hundreds of requests per second) varnish log shows the ldirectord server connecting to it every 5 seconds, but nothing else. I have set up a test site using this configuration, but it fails - no apache access logs, no applicable varnish logs.

  • Centos 6.2 Fresh 'Basic Server' install networking issues

    - by RWC
    I've had a /29 provisioned on a network port for a server and am trying to at least configure the machine so I can ssh into it. It's Centos 6.2 x64 with the Basic Server install. Currently not able to ping gateway or any address for that matter. For reference: Default Interface: em2 Network ID: 66.*.*.0/29 Gateway: 66.*.*.1 Broadcast: 66.*.*.7 Please see my following configs: /etc/sysconfig/network-scripts/ifcfg-em2 DEVICE=em2 NM_CONTROLLED=yes ONBOOT=yes HWADDR=Not Important TYPE=Ethernet BOOTPROTO=none IPADDR=66.*.*.2 PREFIX=29 DNS1=8.8.8.8 DNS2=8.8.4.4 DEFROUTE=yes IPV4_FAILURE_FATAL=yes IPV6INIT=no NAME="System em2" NETMASK=255.255.255.248 USERCTL=no $: route -n Destination // Gateway // Genmask // Flags // Metric // Ref // Use // Iface 66.*.*.0 0.0.0.0 255.255.255.248 U 0 0 0 em2 169.254.0.0 0.0.0.0 255.255.0.0 U 0 1003 0 em2 0.0.0.0 66.*.*.1 0.0.0.0 UG 0 0 0 em2 $: route Destination // Gateway // Genmask // Flags // Metric // Ref // Use // Iface 66.*.*.0 * 255.255.255.248 U 0 0 0 em2 link-local * 255.255.0.0 U 0 1003 0 em2 default 66.*.*.1 0.0.0.0 UG 0 0 0 em2 $: cat /etc/sysconfig/network NETWORKING=yes HOSTNAME=excalibur.domain.com GATEWAY=66.*.*.1 Keep in mind that I cannot even currently ping the gateway which is quite confusing for me. My /etc/hosts are configured correctly with the *.2 address. I'm not concerned with getting all of the addresses on the /29 up and running yet, just one so I can at least ssh in. Thanks!

  • Postfix selective header_checks: smtpd_relay_restrictions vs. smtpd_recipient_restrictions

    - by luke
    Some of my customers implemented commercial software that violate email-RFCs such that we have had to relax our header checks. In consequence, we receive more spam. Prolog: I know the domains (customer.com) and IP-addresses (a.b.c.d/C) these emails come from Kind request for help: Is it possible to setup one Postfix (2.11) instance on Linux such that: It applies only some header checks for emails from .*@customer.com But applies all header checks for all other email sources? I thought of a combination of mynetworks that includes the subnet a.b.c.d/C in smtpd_recipient_restrictions -- allowing all these messages through -- and simultaneously avoid an open-relay with smtpd_relay_restrictions. However, this has not worked out as expected. Any idea or help is highly appreciated. Thanks in advance. Luke ==EDIT== For the current issue, I solved the problem by prepending REDIRECTs to header_checks as follows: /^received: from.*customer.com.*by mail.own.com.*for.*luke@own.*/ REDIRECT [email protected] This works so far as neeeded. Irrespective thereof, I am still looking for a postfix configuration that would turn this text-based setting into an IP-Address-Range based forwarding rule.... Thanks. Luke

  • VMware Server Host-Only Network Routing

    - by Chris
    I have a windows 2008 web server machine running VMware server. I have 3 VM's - All 3 are test servers so security isn't really a concern... each of them running windows 2008 standard and some of them serving web content. My ISP only allows one MAC address to access the physical switch, however they give me 10 public IP addresses to use. My question is, if I put each VM on their own Host only network, how can I route all traffic from a specific public IP on the host, to the corresponding host only adapter, therefore routing to the specific VM? For example: A single physical Adapter on the Host has the following public IP's assigned to it in windows networking: 74.208.14.10 74.208.14.20 74.208.14.30 Each VM is on a host-only network vm1 - 192.168.196.1 vm2 - 192.168.197.1 vm3 - 192.168.198.1 On the host, I want to route all traffic from 74.208.14.10 to VM1 and 74.208.14.20 to VM2 and 74.208.14.30 to vm3 without using VMware NAT, or bridged connections. I want each server to appear to have its own public IP address. My guess is i can modify the route tables somehow, or perhaps in ICS...but i'm not sure how.

  • How have multiple web servers and IPs on the same physical network

    - by jsigned
    I do web development out of a small office and need to have multiple physical and virtual servers that can be accessed from the internet. I also have a number of devices (computers, laptops, tablets, printers, etc) that need connections as well. I have gotten a subnet of 8 IP's from my ISP and while that is adequate for the web servers its far too small for everything that needs access to the network. My router is an ASUS RT-N16 running DD-WRT. I'm just smart enough about this routing topic to be dangerous, think 2 year old with a magic marker. I would like to keep my internal network NAT'ed on the 192.168.x.x network and route the 68.69.x.x 255.255.255.248 traffic directly to the servers. The physical network consists of the 4 port DD-WRT router and an unmanaged gig switch. I have a fiber connection to the office that works as an Ethernet port. In other words I can plug my laptop directly into it and have access to the internet. There is no login or password and the router is setup to get DHCP from the ISP, and to provide DHCP addresses for the internal network. What I've done so far is google and try different configurations with little success. In the end I decided I didn't even know how to ask the questions needed. My questions are: Is this the best way to configure the network? How do you do it? VLANs? Multiple routers? I've never had to configure a router using anything more than the GUI so if this is command line stuff be gentle.

  • How to enable Ipv6 on my ubunutu 11.04 virtual machine

    - by liv2hak
    I have installed 3 VM's on my PC.(Ubuntu 11.04).I want to setup an IPV6 network to review and test some of the IPV6 tools like NDPMonitor.(monitors ICMP messages of Neighbour Discovery Protocol.) IP v6 addresses are as follows. linux_router - fe80::a00:27ff:fed5:f7e9/64 labhack1 - fe80::a00:27ff:fed2:8bd1/64 labhack2 - fe80::a00:27ff:fed7:2f2d/64 The below commands have been run on both linux_router and labhack1. sudo ip r a 2001:468:181:f100::/64 dev eth0 sudo vim /etc/radvd.conf /file looks like below./ interface eth0 { AdvSendAdvert on; /*means that we are sending out advertisments.*/ MinRtrAdvInterval 5; /*these options control how often advertisments are sent*/ MaxRtrAdvInterval 15; /*these are not mandatory but valueable settings.*/ prefix fe80::a00:27ff::/64 { AdvOnLink on; /*Says to the host everyone sharing this prefix is on the sam local link as you.*/ AdvAutonomous on; /*Says to a host: "Use this prefix to autoconfigure your address"*/ }; }; sudo sysctl -w net.ipv6.conf.all.forwarding=1 I try to do a ping6 -I eth0 fe80::a00:27ff:fed5:f7e9 I get Destination unreachable: Address unreachable.I am not sure what I am doing wrong here.I am a beginner at linux administration.Basically I think I am missing whatever is analogous to physically connecting VM's.Any help that would point me in the right direction would be greatly appreciated.
