Deniz Zoeteman's questions

I'm currently running Hyper-V in Windows Server 2012, and I'm trying to get a Debian Wheezy VM running. I've configured the virtual switch and added a legacy network adapter configured to the virtual switch, and removed the regular network adapter that was automatically added by Hyper-V.

When autoconfiguring the network during installation, I'm getting "Network autoconfiguration failed". So, I tried to set it up manually, with the same settings that I can see when I use ipconfig /all in Windows. However, with this, I'm getting "Unreachable gateway". Any ideas as to why this is happening?

Just some background info: I currently have 3 IPs for my server, one primary IP and I have set-up two additional IPs in the Virtual Switch's IPv4 advanced configuration. They seem to work, because I can ping the additional IPs. I'm trying to set one of these additional IPs as the IP of my Debian installation.

We are having trouble with our Draytek router, and I thought this would be the best place to ask.

Our current set-up:

• Cisco EPC3925 modem to our connection point
• Draytek Vigor2850 router connected directly to the Cisco modem
• LAN connection through the Draytek router to our local computers, and a VPN set-up for remote access (which is actively being used).
• Some computers have a switch installed between them and the router.
• Local DNS server, routing local websites to our local servers, and all other traffic to Google DNS (8.8.8.8)

We are currently having a problem where our connection dies - We still have internet access according to Windows, but any web browsing, email clients etc cannot resolve to anything apart from our local PCs. We need to restart the router to fix the issue, but this is keeps on happening - anywhere from once a week to once every 5 minutes.

We're wondering if this is bad hardware, software, or maybe a different issue? It cannot be the switch installed, since even the computers who aren't set-up to the switch have the same issue. Connecting to the Cisco modem directly works; internet works fine in that case.

We've also set-up logs to be sent to our e-mail from our router, and we keep having logs like this:

[DOS][Block][fraggle_attack][192.168.5.3:54235->255.255.255.255:8912][UDP][H
Len=20, TLen=29]

Could this be the issue? If so, what could be causing these supposed Fraggle attacks? I can't think of any local PCs that could be causing this, nor do I know of any local PCs that have this IP (all of them are in the 100+ range). Could it be the VPN, or the modem? We also sometimes have this on IP 0.0.0.0 instead of 192.168.5.3.

Edit: We've got a suspicion this is our Intellisense Network Monitor, generating those Draytek DoS blocks.

Any ideas would be appreciated.

I'm currently trying out HTTPS on one of my sites, and I got a trial certificate from a trusted CA. I've gone through the following checklist:

• Copied all the cert files according to the CA's instructions
• Enabled mod_ssl on apache with a2enmod ssl
• Checked PHP has OpenSSL enabled
• Made a new virtual host in Apache listening to 443

• Inputted the SSL directives:

  SSLEngine on

  SSLCertificateKeyFile /etc/ssl/ssl.key/server.key

  SSLCertificateFile /etc/ssl/ssl.crt/api_my_site_com.crt

  SSLCertificateChainFile /etc/ssl/ssl.crt/apimysite.com-bundle

• Checked only apache was listening to port 443 with lsof

• Check locally and from my own PC with telnet if I could connect to 443 (to the IP of the server, not domain; trying to connect to my-site.com:443 gave me connect failed)

However, when I try to browse to https://my-site.com (obviouslly not the real domain), I get a 'Connection Refused' error. This is what Apache logs:

Any ideas why this is happening?

I've also asked this question on Stackoverflow, but I thought this would've been a better place to ask.

We have the following rewrite rule on IIS7.5:

<rule name="Anything else to the event handler" enabled="true" stopProcessing="true">
  <match url="^(.*)$" />
  <conditions logicalGrouping="MatchAll" trackAllCaptures="false">
    <add input="{PATH_INFO}" pattern="^.*(/index.cfm/).*$" negate="true" />
  </conditions>
  <action type="Rewrite" url="/index.cfm/{R:1}" appendQueryString="true" logRewrittenUrl="true" />
</rule>

However, it never puts the /{R:1} after it. It just goes to /index.cfm. We need to actually get the reference variable, because we use this in our ColdFusion (10) scripts. An example url rewrite we would like:

From: http://www.my-site.com/this.is.a.test/another.test

To: http://www.my-site.com/index.cfm/this.is.a.test/another.test

Anyone who has an idea why it won't do this? (quick note: a ColdFusion error may occur when executing the correct URL, but I wouldn't think this would cause problems with rewriting?)

Note, it does actually work when you try the same in a browser (with the rule disabled) - just not with a rewrite rule. With the rewrite rule, cgi.PATH_INFO variable in CF returns empty string.

Also, IIS does say it has rewritten the URL to index.cfm/this.is.a.test/another.test in the logs, which is strange. Using a 301 redirect instead of a rewrite makes it work perfectly fine (did not change anything about the rule, only action type to redirect). THis is to me, very strange, since I would expect rewriting to work pretty much the same as redirecting, just the difference that rewriting is internal.

We have Helicon Ape on our server as well, so if you have a solution for this in mod_rewrite instead of IIS' module, please suggest it.

I've been trying to clone a vm with the vCenter Converter 5.1 software, but I am having trouble with the 2nd vm I tried to do. The first completed with no errors. The second however, will not let me continue on the Destination Location screen on the wizard for converting.

I select the correct datastore, but it does not allow me to continue (the "Next" button is grayed out). However, it does not tell me why, nor does it show anything special in the logs. Anyone out there with experience with this?

The weird thing is, I was able to clone the VM to a different server, but I am still not able to clone it to the server I want it to clone to.

We are currently running one domain with many subdomains for individual clients. These clients all have their own wishes for rewriting rules, and we would like to seperate these rules for each client's subdomain. If possible, we would like to seperate the web.configs.

Is there an easy way to do this in IIS7?

My MySQL server running on a Debian VPS is not allowing external connections. I can connect fine locally, but I do not seem to be able to connect to my server from an external host.

I've made sure it was running on port 3306, and it is. I'm clueless as to why this is happening, and it would be great if someone could help with this.

With my MySQL client I used (HeidiSQL) I got the following error:

SQL Error (2003) in statement #0: Can't connect to MySQL server on ' xx.xxx.xxx.xxx' (10061)

My IIS seems to redirect to Default Web Site when I just type in my site's URL without specifying the actual page (e.g. index.cfm (I run ColdFusion 10)), but when I specify the actual page it works fine. I've set up the Default Document with index.cfm but it just doesn't seem to want to work.

Any ideas?

After trying to upgrade from Coldfusion 8 to Coldfusion 10, I seem to be getting a migration error in the 64bit installer. It seems to be the exact same issue as Moving from ColdFusion 8 to ColdFusion 10 - Migration Fails, but that question is out-of-date and with no reply from either the person who asked the question nor any answer that was marked as accepted.

I am currently running a local DNS server which is configured with one domain controller, having a bunch of domains and those domains have all wildcard entries for any subdomains. I also have WINS enabled for easy file exploring.

My problem that I am having at the moment is that these domains and subdomains do not seem to function (cannot ping them) after a while; when I do ipconfig -release & -renew on the client computer however, I am able to connect to the (sub)domains again for a period of time.

Could this be because I have set-up Google DNS as a secondary DNS server for everything apart from my local domains?

I am running DNS server on a Windows Server 2008 R2 server and IIS on a seperate Windows Server 2003 server which has the actual websites associated with the domains.

I'd also like to note that I seem to be also having the same issue as https://serverfault.com/questions/508571/dns-cache-in-windows-client-not-updating, maybe this is related to this issue?

Is there a way to make only java be allowed to use a certain port?

No access to router (hosted box).

I have a free domain running at x10hosting (x10.bz), and I want to find out the IP Address of my MySQL host for it, so I can contact the MySQL database from another host. I've already added that host to the access list, but now I need to find out the IP Address of the MySQL host. How can I find this out? x10 is using cPanel X and PHPMyAdmin.
