  • Apache SSLProxyMachineCertificateFile does not work

    - by Serge - appTranslator
    I'm setting up an Apache reverse proxy that exposes a client certificate to the remote host. I do it using SSLProxyMachineCertificateFile /etc/tls/pki/certandkey.pem Problem: The remote host does not recognize the client certificate. Notes: certandkey.pem contains the unencrypted key and the cert. from the proxy box, curl -E /etc/tls/pki/certandkey.pem https://www.remote.com works fine. It's a GoDaddy SSL certificate. It's bundled with a gd_bundle.crt. Should I use SSLProxyMachineCertificateChainFile? I'm on CentOS 6.3 with Apache 2.2.15 (SSLProxyMachineCertificateChainFile not available)

  • Managed hosting firewall vs managing own firewall

    - by ddawber
    I posted on stackoverflow as to the overall benefits of managed hosting vs non-managed hosting. The more I think about it, it seems to boil down to one question: should I use a managed host because they take care of the firewall, or would I be okay managing my own, software firewall? The sites on the box do get quite a lot of traffic but as for throughput and what-not, it's not something I know much about. Ideally, i'd take my sites over to a Linode stack and manage incoming connections using iptables or an alternative. Here are some example hardware solutions a managed host would provide: Cisco Pix 501, Pix 506, Pix 515 and ASA 5505 and ASA 5510 Firewalls, configurable in a control panel the likes of an enterprise firewall such as FortiGate 110C Aside from this, I do not need managed hosting, so I appreciate your suggestions.

  • Can't clone gitosis-admin.git local from my snow leopard server running gitosis

    - by joggink
    I've installed gitosis as described here: http://gist.github.com/264304 One of the things that I had to adjust was to give my git user permissions to use ssh (which I did trough server admin - access - ssh and added the 'git' user). When I ssh from my local machine (mac osx) as the git user, I get this response: PTY allocation request failed on channel 0 bash: gitosis-serve: command not found Connection to 10.0.0.108 closed. Which I think is normal, because in Pro GIT the author says you should get something like this if you try ssh'ing to the server using your git user: PTY allocation request failed on channel 0 fatal: unrecognized command 'gitosis-serve schacon@quaternion' Connection to gitserver closed. So far so good, I think? Now when I try to clone my gitosis-admin.git repository using this command: $git clone [email protected]:gitosis-admin.git I get this: Initialized empty Git repository in /Users/joggink/gitosis-admin/.git/ bash: gitosis-serve: command not found fatal: The remote end hung up unexpectedly So after doing some searching, I found an answer here on serverfault claiming I should use ssh:// as protocol for my git clone (which I thought is the default git protocol?) However, when I try: $git clone ssh://[email protected]:gitosis-admin.git This is the response: The authenticity of host ' (::1)' can't be established. RSA key fingerprint is 80:4d:77:c7:78:cb:c9:42:e3:82:06:7c:fe:c0:08:ce. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '' (RSA) to the list of known hosts. Password: Password: Password: Permission denied (publickey,keyboard-interactive). fatal: The remote end hung up unexpectedly When I type in my own password (because my git user has no password), I get following error: The authenticity of host ' (::1)' can't be established.

  • Ubuntu keyboard detection from bash script

    - by Ryan Brubaker
    Excuse my ignorance of linux OS/hardware issues...I'm just a programmer :) I have an application that calls out to some bash scripts to launch external applications, in this case Firefox. The application runs on a kiosk with touch screen capability. When launching Firefox, I also launch a virtual keyboard application that allows the user to have keyboard input. However, the kiosk also has both PS/2 and USB slots that would allow a user to plug-in a keyboard. If a keyboard were plugged in, it would be nice if I didn't have to launch the virtual keyboard and provide more screen space for the Firefox window. Is there a way for me to detect if a keyboard is plugged in from the bash script? Would it show up in /dev, and if so, would it show up at a consistent location? Would it make a difference if the user used a PS/2 or USB keyboard? Thanks!

  • awstats parse of postfix mail log drops all records

    - by accidental admin
    I'm trying to get awstats to parse the postfix mail log, but it drops allmost all entries with messages like: Corrupted record (date 20091204042837 lower than 20091211065829-20000): 2009-12-04 04:28:37 root root localhost 127.0.0.1 SMTP - 1 17480 Few more are dropped with an invalid LogFormat: Corrupted record line 24 (record format does not match LogFormat parameter): 2009-11-16 04: 28:22 root root localhost 127.0.0.1 SMTP - 14755 My conf LogFormat="%time2 %email %email_r %host %host_r %method %url %code %bytesd" I believe matches the log format (and besides is the log format I've seen everywhere for awstats mail parsing). Besides, is the same entry format as all the other entries in the mail log. Whatever is left is dropped too: Dropped record (host localhost and 127.0.0.1 not qualified by SkipHosts): 2009-12-07 04:28:36 root root localhost 127.0.0.1 SMTP - 1 17152 I added SkipHosts="" to the .conf file but to no avail. I feel like awstats really has some personal quarrel with me today.

  • Hardware firewall vs VMWare firewall appliance

    - by Luke
    We have a debate in our office going on whether it's necessary to get a hardware firewall or set up a virtual one on our VMWare cluster. Our environment consists of 3 server nodes (16 cores w/ 64 GB RAM each) over 2x 1 GB switches w/ an iSCSI shared storage array. Assuming that we would be dedicating resources to the VMWare appliances, would we have any benefit of choosing a hardware firewall over a virtual one? If we choose to use a hardware firewall, how would a dedicated server firewall w/ something like ClearOS compare to a Cisco firewall?

  • Fedora to Fedora remote desktop does not work (connection closed error, even after setting everything up)

    - by jonderry
    I'm trying to use remote desktop on my laptop (running Fedora) to my desktop (also running Fedora) on the same local network. I configured Remote Desktop on my desktop via System - Preferences - Remote Desktop, verified that the port is open by nmap, and attempted to connect from my laptop via vinagre (also tried appending :5900 for the port, and using the ip address). In all cases, the connection fails with a popup that says "Connection closed\n Connection to host was closed." EDIT: I am able to use vinagre from the desktop to remote desktop into itself, just not from one machine to the other. I tried vncviewer and a similar problem occurs (unable connect to socket: No route to host (113))

  • Dual Exchange 2010 on different VM + single public IP + multiple domains

    - by Shivan Raptor
    Here is the scenario: I have 2 Exchange Server 2010 on 2 different Virtual Machines, created by and based on Hyper-V. They have IP and domain: 192.168.5.11, domainA.com ; and 192.168.5.12, domainB.com respectively. The problem is, I only have 1 public IP, say 123.123.1.1 . How do I configure the settings so that I can successfully receive emails using both Exchange servers? Given that I cannot use single Exchange server for multiple domains. -- UPDATE -- To clarify, the domainA.com and domainB.com mentioned above are website domains, instead of multiple Active Directory forests. Users of the two Exchange Server shares the same Active Directory. I know that ONE Exchange Server can handle multiple domains, but I would like to separate them into different Virtual Machines, for load balancing and data separation.

  • vSphere Client vCenter Template Customization Specification Using Windows Sysprep Unattended Answer XML File

    - by Brian
    I'm trying to setup a vSphere Client vCenter v5.0.0 Build 455964 Template Customization Specification using a Windows Sysprep unattended answer XML file for Win2008R2. However I didn't know how Sysprep worked before attempting this so it was a time-consuming nightmare (even after reviewing VMware vSphere ESXi 5's documentation)! I think I've figure out what I'm supposed to be doing, but it's still not working. The biggest problem at this point is that vSphere Client vCenter Customization Specification IP address information is not sticking when I load a Sysprep XML file with just 1 basic setting! This can only be a bug. Here is the process I'm using: PROCESS for Windows - vSphere Client Install Windows OS install VM Tools customize Windows (GPOs can be used to do this after deployment) install Applications (GPOs can be used to do this after deployment too) shutdown the VM convert the VM to a template create a custom Windows Sysprep XML answer file with desired customizations View Management Customization Specifications Manager create "New" Specification for "Target Virtual Machine OS" select Windows check "Use Custom Sysprep Answer File" (ADDS: Custom Sysprep File. KEEPS: Network (IP), Operating System Options (SID, Sysprep /generalize). REPLACES: Registration Information of Owner Name & Organization, Computer Name, Windows License (Key), Administrator Password, Time Zone, Run Once, Workgroup or Domain) name it as "VMwareCS-OS####R#x32/64w/Sysprep-TEST" (CS=Customization Specification) set Description as "Created YYYY/MM/DD by FLast" NEXT import a Sysprep answer file from secure location NEXT Custom settings NEXT click "..." box to right of "Use DHCP" set "Use the following IP settings:" for "IP Address" fill out the first 2 octets set appropriate values for other 2-3 fields set DNS server addresses OK NEXT check "Generate New Security ID (SID)" ALWAYS as template is likely a domain-member computer so it can be updated occasionally NEXT Finish View Inventory VMs and Templates right-click previously completed template Deploy Virtual Machine from this Template provide the new OS name (max15char) select inventory location NEXT select Host/Cluster (wait for validation to succeed) NEXT select Resource Pool (wait for validation to succeed) NEXT select Storage location NEXT check "Power on this virtual machine after creation" select "Customize using an existing customization specification" select desired specification select "Use the Customization Wizard to temporarily adjust the specification before deployment" NEXT NEXT Custom settings? NEXT check "Generate New Security ID (SID)" ALWAYS as template is likely a domain-member computer so it can be updated occasionally NEXT Finish Finish. I know a community member named "brian" (http://serverfault.com/users/25904/brian) has worked with this scenario before, but I couldn't figure out how to contact him directly, so Brian if you see this message could you provide some information to help? Thanks, Brian

  • Multiple IP addresses on one NIC register twice in DNS server

    - by Brad B.
    Hi, We've got a build server (Windows Server 2008 SP2, 64-bit) which has one NIC and two IP addresses registered to that NIC (192.168.1.30 and 192.168.1.31). The build server is registering two identical Host (A) records for itself in our DNS server: buildserver.example.com = 192.168.1.30 buildserver.example.com = 192.168.1.31 I know in the "Advanced TCP/IP Settings" window for the build server's NIC, under the "DNS" tab, there is a check box labeled "Register this connection's addresses in DNS". I only want ONE of the IP addresses (ending in .30) to be registered in DNS not both of them. Can that be done? My best guess is to disable the "Register this connection's addresses in DNS" and manually add the Host (A) record to our DNS server. Thanks for any help!

  • No apache MPM package installed error

    - by Sejanus
    I'm getting "No apache MPM package installed" when trying to configure virtual hosts on apache2.2. I compiled apache2.2 from source and I did not use --with-mpm=NAME option. I thought it will compile with default one then. So the question is, is there any way to check if MPM is installed indeed and I only need to enable it somewhere? If it is not, is there any way to add it without recompiling apache? Or, is there any way to have virtual hosts without it at all? I was doing vhost configuration as per this example. Thanks in advance for your help ;) EDIT: prefork is installed. The question is, why after a2ensite / a2dissite and /etc/init.d/apache2 reload I still get error "No MPM package installed"...

  • How can I make check_nrpe wait for my remote script to finish executing?

    - by Rauffle
    I have a python script that's being used as a plugin for NRPE. This script checks to see if a process if running on a virtual machine by doing an SSH one-liner with a "ps ax | grep process" attached. When executing the script manually, it works as expected and returns a single line of output for NRPE as well as a status based on whether or not the process is running. When I attempt to run the command setup to execute this script (from my Nagios server), I instantly get the output "NRPE: Unable to read output", however when I run the script manually it takes about a second before it returns output. Other commands run just fine, so it would seem like NRPE needs to wait a second or two for output rather than instantly failing, but I've been unable to find any way of accomplishing this; any tips? Thanks PS: The virtual machines are not accessible from anywhere other than the host machine, hence the need for the nrpe plugin to ssh from the host into the VM to check the process.

  • Very High Interrupt CPU usage in Win2k3 VM on vSphere

    - by Darragh
    Hi, I've been testing some software in a server virtual environment and I've noticed I get a huge amount of CPU usage on the Interrupts process. My question is, how does this relate to the virtual hardware platform as the rate is allot lower in a real system. Some how the hypervizor scheduler works hard to over come this problem but not as well as on real hardware does. Obvious things are high I/O and disk access but this application mostly just sits and works in memory allot. If anyone has experienced the same, please let me know. thanks in advance Screenshot: Process Explorer

  • What are industry standards and professional best practices in network hosts naming? [closed]

    - by Ivan
    Possible Duplicate: Naming convention for computers It seems an important and difficult dilemma for me how to name network hosts (routers, servers (while a server can be a router and host diverse services at the same time), virtual machines (while they host important services and can migrate), workstations and notebooks (using pc-username is not the best idea as users may change), printers & MFUs, surveillance IP cameras, etc). Are there known and accepted best practices for this task? Excuse me if there already was a similar question here (I think it probably was), I haven't found it.

  • Distinction between Cloud Servers and VPS

    - by Frank V
    What is the distinction between a Cloud based host and a VPS? I talked to a Rackspace Cloud sales person for around 45 minutes and never came to a real conclusion on this. So, to elaborate on my question a bit -- what benefits might a "cloud" server provide me versus a VPS provider such as Linode and vice versa -- what benefits would a VPS provide over a cloud provider? From what I've been able to ascertain, when you host on a cloud (with Rackspace Cloud) you get a instance of Linux in which you install software and such (a LAMP, for instance). From what I can figure, if the instance is running, I am charged and the pricing on Rackspace (according to what I understood from the sales rep) comes out to about $20 a month.... I was thinking a cloud customer pays per processing hours -- so if your app just sits there, no charges are incurred. Does one not pay of the cloud instance is shut down, perhaps? A similar questions to what I'm asking but not exactly it: Understanding: cloud-server, cloud-hosting, cloud-computing, the cloud What is the difference between vps and cloud hosting

  • CentOS 5.5 APIC issue on ESX 4.1 & ML115

    - by Adnan
    Hi, I've just installed vSphere 4.1 on an HP ProLiant ML115 G5 Quad-core and am trying to install CentOS 5.5 as a guest system. However, when the guest boots up I get a calibrate_APIC_clock warning and a kernel panic message. I've come across this knowledge base article on the vmware website which suggests moving the guest onto another Intel based host (!). Funnily enough I don't have a collection of spare host servers sitting around, so can anyone suggest another solution? Alternatively, would installing an earlier version of CentOS get around this issue, or would a yum update put me back to square one? How about BIOS settings, could anything be tweaked there? Thanks.

  • Nginx rewrite rule for Zimbra

    - by Yusuf
    I'm trying to write a rewrite rule for Zimbra, which will allow me to use a hostname to access the Zimbra Desktop Web UI instead of the IP address and port. The default Zimbra URLs are like this: http://127.0.0.1:port/?at=long-encrypted-user-id http://127.0.0.1:port/zimbra/?at=long-encrypted-user-id http://127.0.0.1:port/desktop/login.jsp?at=long-encrypted-user-id Here's what I have till now: server { server_name hostname; location / { proxy_redirect off; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://127.0.0.1:port/; } } This only replaces http://hostname by http://127.0.0.1:port in the background; Where I'm stuck is adding the ?at=long-encrypted-user-id to the URLs. Can somebody help?

  • Are spurious TCP connections on port 53 a problem?

    - by Darren Greaves
    I run a server which amongst other things uses tinydns for DNS and axfrdns for handling transfer requests from our secondary DNS (another system). I understand that tinydns uses port 53 on UDP and axfrdns uses port 53 on TCP. I've configured axfrdns to only allow connections from my agreed secondary host. I run logcheck to monitor my logs and every day I see spurious connections on port 53 (TCP) from seemingly random hosts. They usually turn out to be from ADSL connections. My question is; are these innocent requests or a security risk? I am happy to block repeat offenders using iptables but don't want to block innocent users of one of the websites I host. Thanks, Darren.

  • SSRS 2008 & MOSS 2007 Alternate Access Mapping Problem

    - by Mauro
    I have a MOSS Server with SSRS 2008 Ent Ed configured in Sharepoint Integrated mode. It all works well as http://servername:88/ on the default host header. MOSS works fine using the external host name too on the intranet AAM field (http://site.domain.com/) however SSRS fails on the same url with the message: An unexpected error occurred while connecting to the report server. Verify that the report server is available and configured for SharePoint integrated mode. I think the issue is further complicated by our Windows 2008 infrastructure in which we've never been able to get SPN's working for Kerberos. SQL Server however, is on the same machine so I dont think it is a kerberos double hop issue. Extra info MOSS/SSRS are on a VM running Windows 2003 R2 VM is hosted on Win2008 HyperV DC is on Windows 2008 SBS

  • How to permanently add wireless interfaces with iw

    - by walli
    How can I permanently add virtual wireless interfaces to my network configuration with iw? I created the following interfaces: iw phy phy0 interface add vwlan0 type station iw phy phy0 interface add vwlan1 type __ap The first is configured as a wifi client connecting to an existing network (wpa_supplicant) The second is configured as wireless hotspot (hostapd + dnsmasq) The setup works, but now I can't quite figure out what the best strategy is to save this configuration permanently. Have made an init script for wpa_supplicant Have made an init script for the hotspot Virtual adaptor network settings set in /etc/network/interfaces But all this depends on the wireless interfaces being created. What would be the best way to make sure these interfaces are created before the network is set up and the services are run? As a bonus, since this wireless interface is a usb device, would it be possible to have the interfaces created (and the services started) when the interface is hotplugged? I know you can execute code after a network interface is up, but the wlan0 interface that is hotplugged should never be up. Operating system is raspbian
