• Remove apache from ubuntu

  - by Keyo

  I want to remove apache as if it was never installed, no config files left behind. I intend to reinstall apache2 fresh. I have tried various combinations of apt-get options to no success. apt-get remove apache2 apt-get remove --purge apache2 apt-get purge apache2 apt-get autoremove apache2 None of these totally remove apache properly. Nothing works, the /etc/apache2 directory still exists. So I deleted it. When I install apache the folder is never created. Running Ubuntu server 10.10.

• static routes, cisco ASA, remote locations

  - by Jeff

  192.168.3.1(ASA) - 192.168.2.1(ASA) - ( internet ) - 192.168.1.1(ASA) DomainController, FS, Exchange 192.168.0.1(ASA) - above is a rough idea what my network setup looks like. each internal ip (192.168.x.x) is located behind an ASA. Each location has a different gateway for the internet. They all talk to the 192.168.1.1 network for dns, dhcp, dc, exchange and so on. They can only see the 192.168.1.1, they can not see each other. In my Static Routes on my 192.168.1.1 ASA, should i have them configure as follows? example: 192.168.x.x 255.255.255.0 Locations_Internet_Gateway_IP OR 192.168.x.x 255.255.255.0 Main_Locations_Internet_Gateway_IP not sure which configurtation is correct, thanks in advance for any help!

• SSL certificate for ISAPI redirected Web Site

  - by Daniel

  I have a Win 2003 server and I'm using Ionics Isapi Rewrite Filter to redirect requests made to a Web Site configured in IIS to another Apache2 Server in a server not exposed to the Internet. The Web Site has its host headers configured to catch requests for the specific site, and the redirection is being done with the ProxyPass directive. This is working OK. So far the scenario, my question is: I'd like to add a server certificate to the Apache server, but I don´t know if I need to add the certificate to both Apache and IIS sites. I think I still don´t get the theory behind this and would like to know from someone with expertise in the field the right way to implement this. Thank you in advance.

• Mac OS X: pushing all traffic through a VMWare VM [closed]

  - by bj99

  I want to set up an Astaro (Sophos) UTM in a Virtual Machine. The Setup should be at the end the following: Cable Modem (one IP adress) | [Ethernet] Sophos UTM (running as VM [VMWare Fusion 5] on the MacMini) | [WIFI] Airport Express v2 (for sharing Local Network to wireless and wired clients) 1)| [WIFI] 2)| [Ethernet over Thunderbolt Ethernet Adapter]* Clients MacMini (Local File Server) *To have the Mini also protected behind the UTM So the setup process for the UTM works fine, but then the problems start: I just have one external IP (from my cable modem provider)== So if I put the VM in briged mode my Internet connection drops, because the MacMini also has its IP adress. If I put the VM to NAT mode the Mini itself is not protected by the UTM So: is there a way to hide the en0 interface(Ethernet) and the en1 interface (Wifi) from the MacMini, so that they not even appear in System Preferences Network section but are available to the VM? That way the Mini must connect to the en2 interface (Thunderbolt adapter) to make any Internet/LAN connection and I just use the given single IP from the Cable Modem. Thaks for any suggestions...

• Multiple External IP Ranges on a Juniper SSG5

  - by Sam

  I have a Juniper SSG 5 firewall in a datacenter. The first interface (eth0/0) has been assigned a static IP address and has three other addresses configured for VIP Nat. I have a static route configured at the lowest priority for 0.0.0.0/0 to my hosting company's gateway. Now I need to configure a second IP block. I have the IPs assigned to the second interface (eth0/1) which is in the same security zone and virtual router as the first. However, with this interface enabled I (a) can't initiate outbound sessions (browse the internet, ping, DNS lookup, etc) even though I can access servers behind the firewall just fine from the outside and (b) can't ping the management IP of the firewall/gateway. I've tried anything I can think of but I guess this is a little above my head. Could anyone point me in the right direction? Interfaces: ethernet0/0 xxx.xxx.242.4/29 Untrust Layer3 ethernet0/1 xxx.xxx.152.0/28 Untrust Layer3 Routes: http://i.stack.imgur.com/60s41.png

• What is the best MTA setup for a home/laptop computer (*not* server)?

  - by thomasrutter

  Hello, What is a good MTA (e.g. Postfix or something else) setup for a home computer behind a NAT, or a laptop that is not always online? I've read a lot of Postfix tutorials on how to set it up this way or that, but they are usually geared towards computers that are servers ie they have a static IP have a domain name are always connected to the same network My requirements are, I guess: Ability to redirect mail for local users to another server of my choosing. No listening for incoming SMTP connections - outgoing only Ability to route outgoing mail via an external SMTP server with authentication (and perhaps encryption) If not Postfix, I need an MTA which can queue up mails in case it temporarily has no internet connection.

• VMWare Server 2 Install is Failing w/ Error 25032: "failed to customize windows logon process"

  - by Justin Searls

  VMWare Server 2 install question here.* Straightforward question that would probably require a VMWare expert to pull apart, given that Google has been totally worthless on this. On a patched Windows XP machine, any attempt to install VMWare Server 2.0.1 results in failure, just prior to completion (progress bar is full but I can tell network adapter stuff hasn't been fired yet and most of the services haven't been instaled). The error: Error 25032. Failed to customize Windows logon process (). Please contact your administrator. Upon dismissing the error, you're treated to: Warning 25033. Failed to remove Windows logon customization (VMGINA.DLL). Please contact your administrator. Clicking "OK" rolls back your installation. Killing the installer and hoping that it somehow leaves a working install behind was also unproductive. *I hope install troubleshooting isn't outside the purview of serverfault, I'm typically an SO user.

• BlueCoat reverse proxy NTLM authentication

  - by mathieu

  Currently when we want to access an internal site from Internet (IIS with NTLM auth), we have two login screens that appear : step1 : LDAPAuth, from the BlueCoat that check login/password validity against Active Directory step2 : NTLM auth, from our application. Is it possible to configure the reverse proxy to use the LDAP credentials provided at step1, and give them to whatever application that requests them ? Of course, if those credentials aren't valid, nothing happens. We're using BlueCoat SG400. Update : we're not looking for SSO where the user doesn't have to enter a password. We want the user to enter his domain credentials in the LDAPAuth dialog box, and the proxy to reuse it to authenticate against our application. Or any application that uses NTLM. We've only got 1 AD domain behind the reverse proxy.

• Website requests not reaching IIS?

  - by pete the pagan-gerbil

  To start off with a confession, I am not a server admin - just a developer tasked with getting to the root of a problem. Please be gentle! I have an intranet ASP.NET website running in IIS on a virtual machine. The website is not accessed very often (the last IIS log file was modified nearly six months ago). Both the IP address and Host header value are now failing to return the website, and the IIS log still doesn't show any more recent activity. The virtual machine was moved to a different physical location a few months ago, and the IP address for it has changed. Could this be what has broken access to the site? What else should I be checking to solve this? I don't have totally unrestricted access to the building's network settings, structures, etc. I would be grateful for any advice, even if I can't use it myself it'll improve my knowledge of what's going on behind the scenes!

• Exception while bamboo is checking for changes in svn

  - by tangens

  While configuring a new test plan in Atlassian bamboo, I get the following exception in the log: Recording error: Unable to detect changes : <projectname> Caused by: org.tmatesoft.svn.core.SVNException: svn: Unrecognized SSL message, plaintext connection? svn: OPTIONS request failed on <repo-path> I tried to access the svn repository by hand and it worked (URL looks like this: https://myrepo.org/path/to/repo). The svn sits behind an apache http server. Both the bamboo server and the svn server are running Debian 4.0. Has anybody seen this error before and can give me a hint how to fix it?

• Force Steam (and other programs that do not specify proxy settings) to use a proxy

  - by joshhunt

  My school requires a proxy for all internet access. If you want to use the internet, it is impossible to not use a proxy. This makes it a problem for many programs that don't seem to let you enter proxy settings. How can I use Steam when I am behind a proxy? Is it possible to somehow enter the details into a configuration file, or force it to get the settings from Internet Explorer? If not, does software exist for creating a 'virtual' network adapter which will pass all traffic (or all protocol x traffic) through the proxy? Although I am facing this specific problem on Windows 7, solutions for all operating systems are welcome.

• smartctl or hddtemp for xvda [on hold]

  - by HST

  I'm trying to check the state of the drives on a remote server running Debian wheezy. I'm using a software RAID10 on top of, I guess, xen, since the entries in /dev are /dev/xvda and /dev/xvdb But it I try smartctl -a /dev/xvda I get /dev/xvda: Unable to detect device type Smartctl: please specify device type with the -d option. I've tried various device type guesses, none work Similar problem with hddtemp, which reports ERROR: /dev/xvda: can't determine bus type (or this bus type is unknown) I've searched the smartmontools documentation, but can't find any discussion of virtual disks. . . How do I get behind the virtualisation to something smart tools or hddtemp can work with?

• ssh port forwarding / security risk

  - by jcooper

  Hi there, I want to access a web application running on a web server behind my office firewall from an external machine. We have a bastion host running sshd that is accessible from the Internet. I want to know if this solution is a bad idea: Create an account on the bastion host with shell=/bin/false and no password ('testuser') Create a ssh RSA key on the external machine Add the public RSA key to the testuser's authorized_keys file ssh to the bastion host from the external host using: ssh -N 8888:targethost:80 run my tests from the external host shut down the ssh tunnel I understand that if my RSA private key were compromised then someone could ssh to the bastion host. But are there other reasons this solution is a bad idea? thank you!

• Linux (Kubuntu 9.10): Strange DNS problem [seems to be IPv6 issue]

  - by Homer J. Simpson

  Hi, I'm experiencing strange problems with my Kubuntu 9.10 when doing DNS requests from various applications. The requests are extremely slow, so loading any pages in Firefox or Konqueror, doing package installations in Kpackagemanager and other apps is really painful, while for example Opera doesnt have any problems, and ping is normally fast as well for DNS pings. I checked the proxy settings of both the used applications as well as of the general system and there are none, so to me it doesn't seem as there was something inbetween.. Does anybody have an idea on what to check for possible problem sources or how to solve this ? I'm behind a DSL home router which does the DHCP (and works well with my other computer). Any kind of advice would be really helpful. Edit: It seems to be some kind of IPv6 problem, as I could get it to work by disabling IPv6 explicitly in Firefox. Is there a general solution to this ?

• website not accessible with IIS6 while NAT is configured in Windows 2003

  - by Mohammed Rizwan

  I have Windows2003 server configured with IIS 6. Until now it was working fine, but since I enabled NAT for my users to access the internet via this server, the website becomes unavailable. Note that I have two nics on the server one is WAN and 2nd is for LAN. Both IPs are behind the firewall. If I stop the NAT then the website is available externally. I tried to search the answer in this forum but didn't find appropriate one or maybe didn't properly understand. I'll appreciate if anyone can help me sorting out this issue.

• Restrict access to ESXi

  - by kdl

  What is the best option to restrict access to ESXi machine so that it could be managed using VSphere client from only certain hosts? I know there is no built-in firewall and everyone recommends placing an ESXi machine behind a firewall, but when this is not an option... Is there any other option like using hosts.allow/deny or anything else? Or I better use ESX instead of ESXi? Edit: In the given circumstances, I am not able to add any additional hardware or use things like managed switches.

• Posting data from multiple servers routing through one server to client server

  - by Swaroop Kundeti

  I have 5 webservers behind Load balancer and we have a client server at other end. Client has white listed my 5 webserver public ip so that my webservers will post a file to the client server. Here the problem is my webservers is going to increase and i cannot always ask client to make my new webserver ip's white list. So i would like to make my infra this way, my webservers will post data to the client server routing from a single server. Like assume that web-1 is main server and the remaining 4 web servers will post data to client server routing through main web-1. I was told that this can be achieved by doing IP Tunneling. But i have no idea how to do that. Would be great for any kind of help.

• recipient_delimiter in MS-Exchange

  - by guettli

  Most UNIX mail server support recipient delimiters behind a plus sign in email addresses. [email protected] In the above example "everything" could be any string, and the mail should get into the mail box of the user "user". In postfix it is called recipient_delimiter: http://www.postfix.org/postconf.5.html#recipient_delimiter Is this possible with Exchange 2010? Usecase1: The user can use different email addresses. He can use [email protected] for the communication with "fooshop". If he gets spam mail to this address later, he knows that fooshop has given his address to someone else. Usecase2: We run a ticket system ( http://tbz-pariv.de/software/modwork/ ) and want to add send scans via email to the system. The network scanner can only modify the to-address and we want to insert the ticket type like this [email protected]

• Full speed internal switch bandwidth but per-port set external bandwidth?

  - by garg

  I am in an environment where all the machines are behind a switch that I don't have access to. Each ethernet wall port has limited bandwidth depending on how much has been paid for each port. The problem is that some people have 10Mbps connections and some have 100Mbps connections and this causes problems with local intranet file transfers and operating system/software deployments. Operating systems can take hours to be deployed if the machine is on 10mbps. Do you know if it is possible with most switches to set a rule that would limit bandwidth coming in/going out to an extranet, but keep full bandwidth if the packets are destined to go to a local machine? For example, the internet might be limited to 10Mbps, but internal servers would get gigabit speeds? Thanks

• Asterisk: Forcing a sip peer to connect via ipv6?

  - by growse

  I've got an asterisk server that connects to an upstream provider over a WAN. The upstream provider supports both IPv4 and IPv6 connectivity, and the asterisk server is behind a NAT. When asterisk connects to the upstream sip peer via IPv6, everything works perfectly. The issue I have is that when I configure the asterisk server IPv6 address via DHCPv6, a race condition means that asterisk sometimes ends up attempting to contact the upstream peer via IPv4 (the SIP DNS name has both A and AAAA records). This is because asterisk starts up before the system has a valid IPv6 address. The connection does not work via IPv4 because of the NAT. Is there a way of configuring the peer to specify that it should only be contactable over IPv6? I guess it might be possible to hack together a firewall rule to deny all IPv4 traffic to that IP, but it'd be easier to configure this within asterisk itself.

• Multi-monitor aterm transparency

  - by Bryan Ward

  I have 3 monitors which I set the background with using xpmroot my-5760x1200bg.png I then setup aterm to use transparency by adding the following to my ~/.Xdefaults file. aterm*transparent:true aterm*shading:60 aterm*background:Black aterm*foreground:White aterm*scrollBar:true aterm*scrollBar_right:true aterm*transpscrollbar:true aterm*saveLines:32767 aterm*font:*-*-fixed-medium-r-normal--*-140-*-*-*-*-iso8859-1 aterm*boldFont:*-*-fixed-bold-r-normal--*-*-140-*-*-*-*-iso8859-1 I am getting transparency on my aterm windows, but the image that is coming through with the transparency isn't correct. On the left monitor things are fine, but the middle and right monitors both seem to use the leftmost 1920x1200 of the background image as what is behind the terminal window. It would be as if every screen had the same background as the monitor on the left. Is this something that can be configured to be correct, or is this a bug? I'm running Gentoo Linux with Xmonad.

• Re-using port 443 for another service - is it possible?

  - by Donald Matheson

  The ultimate goal is to allow a remote data connection service to operate on port 443 on a the SQL server. The application accessing the connection is behind a firewall and it is because of the client's reluctance to open another port that I have been asked to try and get this working. The current environment is Windows 2003 R2 (SP2) and SQL Server 2005. IIS is not installed, but when I try and install the third party connection software (SequeLink) it won't as it reports something is still configured on/using port 443. Netstat does not show anything listening on the port and I've tried editing the system32\drivers\etc\services file removing any reference to port 443 and also using sc delete to delete the HTTP and HTTPFilter (HTTP SSL in services console) services to see if this would help. Rebooting after each change. What could still be using the port? Is what I'm trying even possible (I have my doubts but have to investigate every avenue)? Any help/pointers would be greatly appreciated.

• Is there a way to bridge two outgoing TCP connections in order to bypass firewalls and NAT?

  - by TK Kocheran

  We're all familiar with the problem of port-forwarding and NAT: if you want to expose something to accepting an incoming connection, you need to configure port-forwarding on the router or conjure up some other black magickery to "punch holes" in the firewall using UDP or something. I'm fairly new to the whole "hole-punching" concept so could someone explain how it works? Essentially, I'd like to understand how hole-punching would work and the theory behind it, as well as if two TCP connections could be bridged via a third party. Since there's no issue with outgoing TCP connections since it's handled with NAT, could a third party bridge the connections so that the two parties are still connected but without the bandwidth cost of traffic going through the third party?

• Powerpoint template image placeholders can't send to back

  - by Marcus

  We want to be able to set up a PowerPoint 2007 template with a picture frame image. We then want to insert an image in normal view which would appear behind the picture frame image that was put in the template (so it looks logically like a picture in a picture frame). Problem is, when we insert the image in normal view it always appears on top of the picture frame image. It appears that you can't send to back when the other elements are included in a template. Any ideas?

• How to Track Duplicate Downloads

  - by user1089173

  I have a product and we are running a campaign for it to allow users to download a trial version. My questions is there any way to detect multiple downloads from the same computer but behind a proxy. For example if a person uses a proxy server, changes his/her ip and downloads our trial version multiple times from different Ip's, is there a way to detect that it is the same person who's downloading the s/w. We use only Name and Email addresses to be entered before downloading our s/w and that can easily be created. We cannot add any other fields to the form (like phoneno.)
