• Horrible time with WAMP, Joomla and Windows 7 (Permissions)

  - by jax

  I have WAMP and Joomla installed on Windows 7. I have made a virtual host outside of the www directory that houses a test joomla site. I have also made a joomla component that I want to install and test on this virtual host. I am having constant problems with permissions. I have given all users full access to the folder containing the files under the security Tab in Win7. It seems to me that when (Apache/PHP) creates a file it put restrictions on the permissions which does not allow it to delete or edit the file anymore so I have to manually go and delete the files when I want to uninstall my component. Also, I cannot install the .zip - instead I have to unzip manually to the tmp folder because when I upload the zip in the Joomla Installer I get the same permissions problems as above. How can I get rid of these issues once an for all?

• Vmware peaks NFS load every 30 seconds

  - by gtirloni

  We were troubleshooting a performance problem on one of our storage servers and after investigating almost everything in sight we saw that every 30 seconds, Vmware would go from 10k IOPS (NFS) to 30k, 50k, 100k or whatever the server would handle. Most of it were reads. What could cause this raise in NFS operations per second every 30 seconds? The virtual machines are managed by external customers and there isn't much in common between them. While breaking utilization down by filename, we discovered 5-10 virtual machines that contributed more to those peaks but it still doesn't explain why every 30 seconds. There are no other peaks outside that 30 sec period (ie. it stays in an almost constant average). Is there an NFS tweak in Vmware to change that 30 second period? If that's really necessary, we would like to introduce some variation so all that workload isn't dropped all at once. It's causing NFS timeout on the ESX 3.5/4.0 hosts when the storage gets overloaded.

• redirect wildcard subdomains to https (nginx)

  - by whatWhat

  I've got a wildcard ssl certification and I'm trying to redirect all non-ssl traffic to ssl. Currently I'm using the following for redirection the non-subdomainded url which is working fine. server { listen 80; server_name mydomain.com; #Rewrite all nonssl requests to ssl. rewrite ^ https://$server_name$request_uri? permanent; } when I do the same thing for *.mydomain.com it logically redirects to https://%2A.mydomain.com/ How do you redirect all subdomains to their https equivalent?

• Asterisk Register username with special character like "@"

  - by Najibul Huq

  I am using a SIP provider that has provided me with a username like: [email protected].com (Note this is only the username part) And has a numerical password. My Register string looks something like this: [email protected]:[email protected].com But this is not working, as asterisk is only sending the first part +112223344 before the first @. My provider is adamant about having the full form of it. This is the first time I am facing this issue that is quite unusual for me. Please help.

• Hostname issue (Linux)

  - by Dremarturg

  Hey, I have a strange problem: I have a mail-server. And I have a strange issue with hostnames on ubuntu. When I send an e-mail there is a line in the headers: Received from domain (ip6-localhost [127.0.0.1]) but my hosts file does not have domain.com The domain does not really fit in since domain.com was just for testing and I want to get rid of this! /etc/hosts and etc/hostname do not have an entry for domain.com. Any ideas? (Reverse DNS is okay)

• /etc/hosts file for a multi-homed, multi-domain machine?

  - by threecheeseopera

  I have a server (debian) with two network interfaces that I would like to host multiple services and domains on; it is not entirely clear to me how the hosts file should be set up. Example: eth0, bound to WAN interface 1.2.3.4: mail.example.com www.example.com eth0:1, bound to WAN interface 1.2.3.5: www.other-domain.com eth1, bound to LAN 192.168.1.123: some-clever-hostname What should my hosts file look like? (including localhost,localhost.localdomain, etc.) Should I use DNS for some of these entries? Which ones? Thanks!

• TCP handshake ok, then the client isn't receiving any packets from the server

  - by infgeoax

  Topology: Client ----- Intermediate Device ----- Server Client: win7 Intermediate Device: unknown Server: CentOS 5.8 The problem occurs when the client and server are trying to establish a SSL connection. It happens to one specific port, 2000. I haven't been able to replicate the problem with other port numbers. I captured packets on both client and server. After the TCP handshake, from the client's perspective, it's not receiving ACKs for its previously sent packets so it kept re-sending them. On the server side, however, it did receive those packets and sent ACK packets. The weird thing is, after the server sent those ACKs, it received a [RST, ACK] packet, from the intermediate device, for every packet it sent. What could be the cause?

• Why won't Windows XP 64 install on my machine?

  - by user272671

  I have a hp xw8200 workstation and would like to install Windowx XP 64 bit on it. Problem I seem to be having is when I reboot the machine and try to boot from the CD, nothing happens. Seems that the CD Drive is not being located or does not execute my cd to start the install. I already checked to verify that I can install Windows XP 64bit on my machine and also ensured I have the right bios and drivers for the install, only that the boot just does not take place. Anyone have any idea how I can solve this problem ? http://www.hp.com/workstations/pws/xw8200/xw8200.pdf http://h20331.www2.hp.com/Hpsub/cache/286710-0-0-225-121.html http://h20331.www2.hp.com/Hpsub/cache/286707-0-0-225-121.html thanks in advance

• How can I find a computer on my network that is doing mass mailings?

  - by Alex Ciarlill

  I was notified by my isp that one of my machines is sending out spam. This happened about 3 months ago on windows machine running cygwin that was hacked due to an SSH vuln. The hackers setup IIS and SMTP. I cleared out the machine and all the services are disabled so I think that machine is okay I am wondering if there is any other way to identify which machine it could be coming from? The ISP has NO useful information such as source port, destination port, destination IP... nothing. I am running DD-WRT on my router, Windows 7 PC and a Windows XP PC.

• hosting website on a private network

  - by razor

  i'm currently running a website off 3 linux servers. I'd like to setup a private network and only allow port 80 traffic to one of the servers. I'd also like to setup a vpn so only I can access the servers via ssh or any port for developing/debugging. How hard is this to setup and what do I need to get? Do enterprise/commercial routers have vpn functionality built in? how do I handle DNS? eg- www.mydomain.com would need to point to the router, which forwards traffic to the webserver. Do I set the A record to the router, and somehow tell the router which server to send the http request to? And how would I make server1.mydomain.com resolve to server1 within the private network (without editing host files)? Would I need to run my own DNS (eg- powerdns?) to do this?

• Block a Server from reaching a machine

  - by user

  I have a Windows 2003 server that I want to block from accessing a specific IP address. I want to control this from the Server. because I control the machine. The traffic is http traffic (webservice call). It uses a non-standard port, so IP address+ Port combination would also work. Background: I have a development enviornment that for some reason is ignoring host file enteries under some circumstances. These host files point the enviornment at services in another Dev enviornment. Wne th host files are ignored, dev is talking to production. This is not my question, rather the motivation for this inquiry. I want is a failsafe to ensure dev will error instead of happily engaging in transactions with production. I control the dev server, I do not control the firewalls or the target production machine.

• Should the virtualization host be allowed to run any service?

  - by Giordano

  I recently setup a virtualization server for the small company I'm running. This server runs few virtual machines that are used for development, testing, etc... My business partner works from a remote location, thus I also installed a vpn server on the virtualization host to make it possible for him to safely reach the company services. Moreover, again on the virtualization host, I installed bacula to perform the backup of the data. Is it advisable/good practice to do so or should I create one more virtual machine to do backups and VPN? Is it a bad idea to run these services on the host itself? If yes, why? Thanks in advance!

• remoting to pc's already setup with pocketcloud

  - by KiloJKilo

  I use pocketcloud to remote desktop into my PCs on my home network. I would like to remote desktop with windows on my laptop via windows 7, but I'm not really sure how to, without breaking pocketcloud's connection. Does pocketcloud change my router's port forward to each machine as needed? Is there a way I can piggyback on the pocketcloud app? It appears to use 3389 but nothing is routed on that port in my router. Any ideas on how to accomplish this?

• 2 RJ45 connectors on a one WAN cable

  - by mr_stavo

  Hello, I encountered strange setup on a network at company where I do some work. They have internet connection from small ISP located in the same building, all I see is one CAT5 cable with 2 RJ45 connectors. One is going to WAN port on the router and another into LAN port on the same router. This is the only way for internet connection to work. I tried to connect my laptop to one of the RJ45 but it won't work. Now, what is the purpose for such setup?

• Does a HDMI-to-DVI (dual link) adapter exist? I don't care about the price

  - by alex k

  My monitor supports full-resolution display (2560x1440) only when connected to through either the DVI-D dual link port, or the DisplayPort. My laptop, though, has neither of these two kinds of output. Instead, all it's got is a HDMI port (which is version 1.3, and I also read that the laptop's graphics chipset supports 2560x1440 at 60Hz). So I'm wondering whether anyone has ever seen an HDMI-to-DVI dual link adapter, which will carry my ultra-highres signal to the monitor I just bought. So far I haven't seen any, and don't even know whether such an adapter (which I understand would have to be active, USB-powered and expensive (but I don't care)) exists.
