  • Multi domain on my dedicated server with Apache2

    - by x4vier
    I setup a server with Ubuntu 10.04 server edition. It's works for a long time with a single domain name. Now i want to add another domain wich will pointed to a new directory. I tried to change my Apache2 configuration but it does not seems to work properly. Here is my /etc/apache2/sites-available/default <VirtualHost *:80> DocumentRoot /var/www/ <Directory /> Options FollowSymLinks AllowOverride None </Directory> <Directory /var/www/> Options Indexes FollowSymLinks MultiViews AllowOverride None Order allow,deny allow from all </Directory> ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/ <Directory "/usr/lib/cgi-bin"> AllowOverride None Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch Order allow,deny Allow from all </Directory> ErrorLog /var/log/apache2/error.log # Possible values include: debug, info, notice, warn, error, crit, # alert, emerg.

Do you have any idea to redirect to the right folder ?

  • How is a subdomain passed to the webserver?

    - by Joshua Frank
    I know that dns resolves an address like example.com to an IP address like 11.22.33.44, but I'm a little confused about how subdomains are resolved, so that when you type http://subdomain.example.com, what actually gets passed to the server at 11.22.33.44? In other words, example.com = 11.22.33.44, but subdomain.example.com/path = ??? Are "subdomain" and "path" passed as http headers, or mapped in the url in some way, or what? Thanks in advance. Edit: If I'm understanding correctly, BloodPhilia says that subdomain.example.com actually is a different domain that in principle could resolve to a totally different IP. But if that's so, then what about hosts that have huge numbers of (what look like) subdomains, but which actually map to some path on the site. For instance, blogspot hosts millions of blogs, and they all look like this: aaa.blogspot.com bbb.blogspot.com ...millions more... yyy.blogspot.com zzz.blogspot.com Those are clearly not subdomains with their own IP's, but rather some mapping like aaa.blogspot.com -- www.blogspot.com/aaa, but how is this accomplished? What actually gets passed to the web server at blogspot.com?

  • ospfd over an OpenVPN link - strange error in logs

  • WebHost Manager - Apache's VHost isn't matching the DNS entry

    - by Trans
    I've used CPanel's WebHost Manager to create a new host on my VPS. I then used my HOSTS file to point fake.com to the relevant IP address. The problem I'm having now is, Apache isn't recognizing the VHost,or something, as it's just loading the default entry and 404'ing every document I try to GET. Here's the VHost entry NameVirtualHost 0.0.0.209:80 NameVirtualHost 0.0.0.211:80 <VirtualHost 0.0.0.209:80> ServerName fake.com ServerAlias www.fake.com DocumentRoot /home/fakecom/public_html ServerAdmin [email protected] ## User fakecom # Needed for Cpanel::ApacheConf <IfModule mod_suphp.c> suPHP_UserGroup fakecom fakecom </IfModule> <IfModule !mod_disable_suexec.c> SuexecUserGroup fakecom fakecom </IfModule> CustomLog /usr/local/apache/domlogs/fake.com-bytes_log "%{%s}t %I .\n%{%s}t %O ." CustomLog /usr/local/apache/domlogs/fake.com combined Options -ExecCGI -Includes RemoveHandler cgi-script .cgi .pl .plx .ppl .perl ScriptAlias /cgi-bin/ /home/fakecom/public_html/cgi-bin/ </VirtualHost> I've Google'd this profusely and all that's being returned is 'DNS errors. Wait for it to propagate'. That's obviously not my problem, since I'm using HOSTS. What else could be causing this? :/ EDIT: Forgot to mention. http://fake.com/~fakecom/test.html loads just fine. So the fake.com is pointing to the right IP.

  • ssh_exchange_identification: Connection closed by remote host

    - by rick
    Firstly, I know that this question has been asked a million times, and I have read everything I can find and still cannot fix the problem. i am encountering this issue when ssh'ing in from my mac to my Ubuntu server on a fresh install of Ubuntu (I reinstalled because of this issue). I have SSH portmapped to 7070 because my ISP is blocking 22. On the client: bash: ssh -p 7070 -v [email protected] debug1: Reading configuration data /etc/ssh_config debug1: Connecting to address.org port 7070. debug1: Connection established. debug1: identity file /home/me/.ssh/identity type -1 debug1: identity file /home/me/.ssh/id_rsa type 1 debug1: identity file /home/me/.ssh/id_dsa type -1 ssh_exchange_identification: Connection closed by remote host Here's what I have done to try to resolve the issue: Made sure my maxstartups is ok: bash: grep MaxStartups /etc/ssh/sshd_config #MaxStartups 10:30:60 Made sure hosts.deny is clear of denials. Made sure hosts.allow has my client IP. Clear out known_hosts on client Changed ownership of /var/run to root Made sure etc/run/ssh is Made sure /var/empty exists Reinstall openssh-server Reinstall ubuntu When I run telnet localhost, I get this: telnet localhost Trying ::1... Trying 127.0.0.1... telnet: Unable to connect to remote host: Connection refused When I run /usr/sbin/sshd -t Could not load host key: /etc/ssh/ssh_host_rsa_key Could not load host key: /etc/ssh/ssh_host_dsa_key When I regenerate the keys with ssh-keygen -t rsa -f /etc/ssh/ssh_host_rsa_key ssh-keygen -t dsa -f /etc/ssh/ssh_host_dsa_key I get the same error. I am pretty sure this is the issue. Can anyone help?

  • Configuring dnsmasq to handle mx records on pfsense 2.0.1

    - by Bob B.
    I know from dnsmasq's man page that it is capable of handling mx records, but I can't seem to find anything in pfsense's web GUI or anywhere online that talks about how to include mx records. I'm running pfsense 2.0.1 on a turnkey hardware appliance. I have root shell access. I would prefer not to move away from using DNS Forwarder/dnsmasq if I can help it. I've searched for a dnsmasq.conf file, but none exists. pfsense handles everything through a centralized xml config file. That file merely designates the dnsmasq section using the tag, then drops immediate into listings for each host override you define. My understanding of pfsense's implementation: In the GUI, you can only define an override using the host, domain, IP and description. In the XML that translates to: <hosts> <host>foo</host> <domain>foo.com</domain> <ip>127.0.0.1</ip> <descr/> </hosts> The above example results in foo.foo.com resolving to 127.0.0.1, for instance. But that's it. No ability to select a record type with which to define things like MX. Anyone had any luck with this? Thank you for any insights you might have.

  • Can't access one directory via HTTPS + public FQDN

    - by Justin James
    Hello - I have the strangest IIS error that I've ever seen in my life. I have an application/directory on an IIS server, that throws an error 500 when accessing ANY of the content in it, including HTML documents, when accessed via HTTPS AND the machines FQDN. When I access it with "localhost" it works fine. When I added a bogus entry for the NIC's IP in the hosts file, it worked fine. When I access it with the machines name and HTTP it works fine. Here's a chart (the machine's name is "lofn.titaniumcrowbar.com"): http - lofn.titaniumcrowbar.com: works https - lofn.titaniumcrowbar.com: broken https - localhost: works https - temp.titaniumcrowbar.com (put into hosts file): works I set up tracing, and I got some useless information: "The I/O operation has been aborted because of either a thread exit or an application request. (0x800703e3)" This would make sense, except this happens when pulling up static content. While the directory may be an "application", the content is all static in it. Any/all suggestions, no matter how strange, are VERY appreciated. Thanks! J.Ja

  • Colorizing your terminal and shell environment?

    - by Stefan Lasiewski
    I spend most of my time working in Unix environments and using Terminal emulators. I try to use color on the commandline, because color makes the output more useful and intuitive. What are some good ways to add color to my terminal environment? What tricks do you do? What pitfals have you encountered? Unfortunately, support for color is wildly variable depending on terminal type, OS, TERM setting, utility, buggy implementations, etc. Here's what I do currently, after alot of experimentation: I tend to set 'TERM=xterm-color', which is supported on most hosts (but not all). I work on a number of different hosts, different OS versions, etc. I'm trying to keep things simple and generic, if possible. Many OSs set things like 'dircolors' and by default, and I don't want to modify this everywhere. So I try to stick with the defaults. Instead tweak my Terminal's color configuration. Use color for some unix commands (ls, grep, less, vim) and the Bash prompt. These commands seem to the standard "ANSI escape sequences" I've managed to find some settings which are widely supported, and which don't print gobbledygook characters in older environments (even FreeBSD4!) (For the most part). From my .bash_profile ### Color support # The Terminal application typically does 'export TERM=term=color' # Some terminal types will print Black, White & underlined with these settings. OS=`uname -s` case "$OS" in "SunOS" ) # Solaris9 ls doesn't allow color, so use special characters instead. LS_OPTS='-F' ;; "Linux" ) # GNU tools supports colors! See dircolors to customize colors export LS_OPTS='--color=auto' # Color support using 'less -R' alias less='less --RAW-CONTROL-CHARS' alias ls='ls ${LS_OPTS} export GREP_OPTIONS="--color=auto" ;; "Darwin"|"FreeBSD") # Most FreeBSD & Apple Darwin supports colors # LS_OPTS="-G" export CLICOLOR=true alias less='less --RAW-CONTROL-CHARS' export GREP_OPTIONS="--color=auto" ;; esac

  • How to point any *.mydomain variation to localhost (for development)?

    - by user41339
    Hi all. I am developing a site, which will make use of any given [variation of] subdomain name part (that is, the part prefixed before the host name and, optionally, the TLD part). I would imagine that in production, that would be an easy feat - make sure the DNS for second-level domain name part points to an IP, set up Apache2 virtual host to listen on that (or any) IP port 80, and just use PHP to make decisions based on the "Host" request header. However, currently the site is localhost, since I am developing it using my workstation, so first I patched the /etc/hosts to include: 127.0.0.1 mydomain I only used one name part (arguably a custom TLD) so as to not interfere with the Internet domain names. Then I set up a VirtualHost directive for Apache 2.2 like: <VirtualHost *:80> ServerName mydomain But now I can see that f.e. example.mydomain does not point to localhost, meaning the the /etc/hosts addition is not effective for "something.mydomain". It appears the rules are taken verbatim, and also I have checked that wildcards like *.mydomain are not allowed. Is there a solution for this?

  • SMTP server closes connection unexpectedly

    - by janin
    I'm writing a python program to send emails, and when trying to send to yopmail, hotmail and some other hosts the connection gets closed by the server without a message. I tried connecting directly with netcat and the same thing happens. Here's what the exchange looks like : $ nc smtp.yopmail.com 25 220 mx.yopmail.com ESMTP *** ehlo mx.myhost.com 250 SIZE 2048000 mail FROM:<[email protected]> 250 OK rcpt TO:<[email protected]> The connection is just closed abruptly at this point. On other hosts, like my ISP's, everything goes fine. I've checked the blacklists but my IP is not listed. Any idea what's going on? Edit: My IP is not listed in any blacklist. I own myhost.com, but I don't have an SPF record. I'll add one and update this post when the record has propagated. Edit 2: with the SPF added the email is now accepted and Hotmail adds a Authentication-Results: hotmail.com; sender-id=pass header to the email. However it gets classified as spam, but I guess that's another matter. Thanks for your help.

  • iSCSI performance questions

    - by RyanLambert
    Hi everyone, apologies for the long-winded post in advance... Attempting to troubleshoot some iSCSI sluggishness on a brand new vSphere deployment (still in test). Layout is as such: 3 VSphere hosts, each with 2x 10GB NICs plugged into a pair of Nexus 5020s with a 10gig back-to-back between them. NICs are port-channeled in an active/active redundant fashion (using vPC-mac pinning for those of you familiar with N1KV) Both NICs carry service console, vmotion, iSCSI, and guest traffic. iSCSI is on a single subnet/single VLAN that is not routed through our IP network (strictly layer2) Had this been a 1gig deployment, we probably would have split the iSCSI traffic off onto separate NICs, but the price/port gets rather ridiculous when you start throwing 4+ NICs to a server in a 10gigabit infrastructure, and I'm not really convinced it's necessary. Open to dialogue/tech facts re: this, though. At this point even a single VM guest will boot slowly to iSCSI storage (EMC CX4 on the same Nexus 5020 10gig switches), and restores of VMs from iSCSI take about twice as long as we'd expect them to. Our server folks mentioned that if we split the iSCSI off onto its own NIC, performance seems significantly better. From a network perspective, I've run through the variables I can think of (port configuration errors, MTU problems, congestion etc.) and I'm coming up dry. There really is no other traffic on these hosts other than the very specific test being performed at the time. Important thing to note is that guest traffic works just fine... it seems storage is the only thing affected by whatever gremlin exists. Concluding that we're not 'overutilizing' the network infrastructure since we're doing hardly anything, I'm just looking for some helpful tips/ideas we can use to resolve this... preferably without hurling extra 10gig NICs that are going to sit around 10% utilization while we've got 70+% left on our others.

  • Data Store/Volume disconnecting. How to resume copy of VMDK?

    - by Serge
    I'm having an issue with my ESXi 4.1 hosts losing the datastore with FC SAN after a power outage. All 3 hosts disconnect so it's definitely a SAN issue. I've tried to resolve the issue on the SAN side with the SAN software support and Adaptec hardware support. No luck there. So I'm stuck with a SAN that will randomly disconnect the volume. I need to get the virtual machines (VMDK files) from the datastore. The problem is I can only get 5-20% before the data store disconnects. I have backups that are slightly older that I can use to replicate the VMDK differences to. What has not worked so far: Powering up the VMs, will boot up for 5-15 minutes then freeze vCenter migrate or clone of VM, will fail after similar period of time vCenter copy/paste of VMDK. Was able to get one 30GB VMDK and no luck after that. vMware Data Recovery. Fails at low %, can't resume, so next backup starts from begining. Veeam Backup & Recovery. Same as above, no resume function. If I can just find a backup solution that will resume from the failed spot that would solve my issue. Anyone have any ideas that I could try? EDIT 1 The SAN is Open-E DSS 6 running on a Supermicro 24 drive enclosure with 4 port Qlogic FC. Adaptec 52445 RAID card.

  • SSH connection problem - allowed from LAN but not WAN

    - by Kerem Ulutas
    I tried to setup my Arch Linux installation to be an SSH host, but here is the thing: I can ssh localhost, it fails to login via public key and asks for username and password, but still able to login. When I try ssh my_wan_ip it gives ssh_exchange_identification: Connection closed by remote host error. I've read all topics about this error and none helped me. By the way, just confirmed, it gives ssh: connect to host my_dyndns_hostname port 22: Connection refused from another machine (outside of my network, it has different wan ip). I have sshd: ALL in "hosts.allow", ALL:ALL in "hosts.deny". I am able to connect to my own pc via ssh, ping my own pc, but my ssh setup seems to be the problem, it gives that annoying error when I try to ssh from wan. /etc/ssh/ssh_config /etc/ssh/sshd_config And finally, here is the debug output for both sshd and ssh: (i ran ssh command and i took output to sshd debug after that): sshd debug ssh debug I can edit my question according to your needs. Just ask for any more information needed. BTW I have no iptables running. I have one cable dsl modem connected to a asus wl-330gE wireless access point, they both have their firewall disabled. I configured NAT so port 22 is directed to the pc I'm having this trouble. Any help appreciated, thanks..

  • DNS Issue- Nameserver Issue

    - by Master-Man
    I setup new server on centos 5.3 and configure dns and hostnam using WHM. I also register my new nameservers with my domain registrar with ns1.example.com and ns2.example.com. But i am unable to ping hostname and NS. ping pc2.example.com or ping ns1.example.com I received the below email from server. IMPORTANT: Do not ignore this email. Your hostname (pc2.example.com) could not be resolved to an IP address. This means that /etc/hosts is not set up correctly, and/or there is no dns entry for pc2.example.com. Please be sure that the contents of /etc/hosts are configured correctly, and also that there is a correct 'A' entry for the domain in the zone file. Some or all of these problems can be caused by /etc/resolv.conf being setup incorrectly. Please check that file if you believe everything else is correct. You may be able to automatically correct this problem by using the 'Add an A entry for your hostname' option under 'Dns Functions' in your Web Host Manager. When I issue the command root@pc[~]# host pc2.example.com I receive the below error that Host pc2.example.com not found: 3(NXDOMAIN) I added A entries for hostname and Nameservers but nothing replies. Its almost more than 72 hours for setting & registering nameservers and dns configurations. thanks,

  • How can I prevent Apache from asking for credentials on non SSL site

    - by Scott
    I have a web server with several virtual hosts. Some of those hosts have an associated ssl site. I have a DirectoryMatch directive in my main config file which requires basic authentication to any directory with secured as part of the directory path. On sites that have an SSL site, I have a rewrite rule (located in the non ssl config for that site), that redirects to the SSL site, same uri. The problem is the http (80) site asks for credentials first, and then the https (443) site asks for credentials again. I would like to prevent the http site from asking and thus avoid the potential for someone entering credentials and having them sent in clear text. I know I could move the DirectoryMatch down to the specific site, and just put the auth statement in the SSL config, but that would introduce the possibility of forgetting to protect critical directories when creating new sites. Here are the pertinent declarations: httpd.conf (all sites): <DirectoryMatch "_secured_"> AuthType Basic AuthName "+ + + Restrcted Area on Server + + +" AuthUserFile /home/websvr/.auth/std.auth Require valid-user </DirectoryMatch> site.conf (specific to individual site) <DirectoryMatch "_secured_"> RewriteEngine On RewriteRule .*(_secured_.*) https://site.com/$1 </DirectoryMatch> Is there a way to leave DirectoryMatch in the main config file and prevent the request for authorization from the http site? Running Apache 2 on Ubuntu 10.04 server from the default package. I have AllowOverride set to none - I prefer to handle things in the config files instead of .htaccess.

  • I go to www.facebook.com, but a completely different site appears.

    - by Rosarch
    I am going to www.facebook.com, but the site that appears is totally different. This occurs on Chrome 6+, IE9, and FF 3+. What could be happening? Is this a security risk? Facebook was working just fine, then all of a sudden this happened. Update: The same problem occurs on my netbook. Update 2: When I go to http://69.63.189.11/, it works fine. So... DNS problem? How do I fix? Update 3: Checked the hosts file: # Copyright (c) 1993-2009 Microsoft Corp. # # This is a sample HOSTS file used by Microsoft TCP/IP for Windows. # # This file contains the mappings of IP addresses to host names. Each # entry should be kept on an individual line. The IP address should # be placed in the first column followed by the corresponding host name. # The IP address and the host name should be separated by at least one # space. # # Additionally, comments (such as these) may be inserted on individual # lines or following the machine name denoted by a '#' symbol. # # For example: # # 102.54.94.97 rhino.acme.com # source server # 38.25.63.10 x.acme.com # x client host # localhost name resolution is handled within DNS itself. # 127.0.0.1 localhost # ::1 localhost Looks like it hasn't been altered.

  • VMware "boot screen" - add info like contact, phone number, etc.?

    - by TheCleaner
    I've tried searching Google and VMware's KB but maybe I'm not typing the right search criteria...only finding ways to fix problems with booting or screen issues. On the default boot screen of a host it looks similar to this picture from GIS: I'm curious if it is possible somehow to make it look like this instead (adding custom details): I know for the most part the info is "useless" since it is administered remotely, etc. But when I deploy standalone hosts to branch offices, it'd be nice for them to see this type of info on the boot screen. I may also include the VMs hosted on it (again on standalone hosts). Normal monitoring, etc. will be done remotely. This is strictly for odd times when the branch contact may say "the electricians are saying they need to turn off this circuit but I have no idea who to call in IT to tell them this box needs to be shut down" or similar. Anyone who has dealt with small branch offices can tell you that if it isn't labeled they easily forget what it is for and will simply say after the incident "I didn't know what it was or who to call." Possible?

Here is my apache config file: <VirtualHost *:80> ServerName example1.com DocumentRoot /home/me/example1/production/current/public </VirtualHost> <VirtualHost *:443> ServerName example1.com DocumentRoot /home/me/example1/production/current/public SSLEngine on SSLCertificateFile /home/me/example1/production/shared/example1.crt SSLCertificateKeyFile /home/me/example1/production/shared/example1.key SSLCertificateChainFile /home/me/example1/production/shared/gd_bundle.crt SSLProtocol -all +TLSv1 +SSLv3 SSLCipherSuite HIGH:MEDIUM:!aNULL:+SHA1:+MD5:+HIGH:+MEDIUM </VirtualHost> <VirtualHost *:80> ServerName example2.com DocumentRoot /home/me/example2/production/current/public </VirtualHost> <VirtualHost *:443> ServerName example2.com DocumentRoot /home/me/example2/production/current/public SSLEngine on SSLCertificateFile /home/me/example2/production/shared/iwanto.crt SSLCertificateKeyFile /home/me/example2/production/shared/iwanto.key SSLCertificateChainFile /home/me/example2/production/shared/gd_bundle.crt SSLProtocol -all +TLSv1 +SSLv3 SSLCipherSuite HIGH:MEDIUM:!aNULL:+SHA1:+MD5:+HIGH:+MEDIUM </VirtualHost> Whats the issue: On restarting my server it gives me some output like this: * Restarting web server apache2 [Sun Jun 17 17:57:49 2012] [warn] _default_ VirtualHost overlap on port 443, the first has precedence ... waiting [Sun Jun 17 17:57:50 2012] [warn] _default_ VirtualHost overlap on port 443, the first has precedence On googling why this issue is coming I got something like this: You cannot use name based virtual hosts with SSL because the SSL handshake (when the browser accepts the secure Web server's certificate) occurs before the HTTP request, which identifies the appropriate name based virtual host. If you plan to use name-based virtual hosts, remember that they only work with your non-secure Web server. But not able to figure out how to run two ssl application on same server. Can any one help me?

  • nginx redirect proxy

    - by andrew
    I have a web app running on a nginx server on local ip 192.168.0.30:80 I have this in my etc/hosts 127.0.0.1 w.myapp.in If someone accesses my app using a "w" subdomain, it shows a webdav interface, otherwise it runs normally (for example, someone calls http://myapp.in , it goes into the app, and http://w.myapp.in goes into webdav interface - this is done within the app, nginx has nothing to do with it) Because I don't have a dns or anything like that, users must access the app by ip. A problem appears if someone wants to access the webdav interface, because you cannot access the app by a subdomain - unless you write a line in your local hosts file, which is not a solution) A possible solution If it's possible to setup the nginx server so that if someone calls http://192.168.0.30 (on port 80), it goes normally into the app, but if a user tries to access say http://192.168.0.30:81 (another defined port) it redirects internally to w.myapp.in, and the app sees the subdomain Given the app, can this be done? If yes, what should I put in the nginx config file? And if you guys think of a better solution, I'm open to any.

  • When should NTPd broadcast/broadcastclient be used instead of client/server or peer modes?

    - by Luke404
    The NTP deamon if often used in its simplest mode, which is client/server: you specify one or more server directives in your ntp.conf and your clients will use those servers. In addition to that, when you run your own NTP servers, it is good practice to peer them together, so if one of them looses connectivity to its upstream servers, it will get time from its peers. But NTPd can also work with broadcast and/or multicast distribution of time data, with the documentation stating: broadcast and multicast modes are intended for configurations involving one or a few servers and a possibly very large client population The documentation also says elsewhere: It is possible and frequently useful to configure a host as both broadcast client and broadcast server. A number of hosts configured this way and sharing a common broadcast address will automatically organize themselves in an optimum configuration based on stratum and synchronization distance. I can see one obvious administrative benefit: you don't have to manually specify and update your list of NTP servers in the clients ntp.conf, so to me it looks tempting to use broadcast mode even for a small client population (say 5+ clients with 3~4 servers). I expect network traffic to be a little higher with broadcasts instead of client/server associations, but given the usual gigabit ethernet LAN the impact should be negligible unless you have a very very large number of hosts in the same broadcast domain. At the end of the day, when should broadcast mode be used or avoided? Are there pros and cons I haven't seen?

  • Creating a Jenkins build farm in a hands-off manner?

    - by user183394
    My colleague and I have set up and run Jenkins on a KVM guest running Ubuntu 12.04 with good results for a while now. We are thinking about deploying a cluster of Jenkins CI hosts in master/slave configuration, with the libvirt slave plugin to keep our hardware count low. Our environment is strictly Linux (CentOS, Scientific Linux, Fedora, and Ubuntu). Both of us are competent in setting up large clusters. We typically use tools like cobbler + a configuration management tool (Puppet, Chef, and alike) to set up a large number of machines (physical and/or virtual) hands off (hundreds of nodes in less than an hour typical). We would like to do the same for nodes running Jenkins. But the step by step guide doesn't give us any clues in this regard. I did see a Multi-slave config plugin. But, being used to dealing with hundreds or more machines completely hands-off, clicking the UI for many machines just doesn't feel right. Can someone point to us a reference that talks about how to set up large cluster of Jenkins CI hosts more in the hands-off way?

  • Can't connect to Server Manager from Windows 7

    - by SAdmin317
    I have a Windows 7 Pro 64bit with SP1 desktop that has RSAT tools installed. I opened Server Manager and can't connect to the server (Server 2008 R2 core). I followed the guide to enable everything on the server, added a registry key to enable read-only on the device manager as well. On the Windows 7 PC I turned on winrm, did the quick config, and added the server IP and name as trusted hosts. I still get an error when connecting. "Connecting to the remote server failed with the following error message: The WinRM client cannot process the requests. If the authentication scheme is different from Kerberos, or if the client computer is not joined to a domain, then HTTPS transport must be used or the destination machine must be added to the TrustedHosts configuration setting...." I also added the name of the server to the windows 7 /etc/hosts file. Ping the server name translates to the IP of the server. Also opened up the firewall for "Remote Volume Management" Both machines are on the same Workgroup, using the same Administrator account, with the same password. Any help appreciated.

  • Apache + Tomcat: Which one should handle SSL? IP-based proxy forwarding?

    - by delirial
    We currently have a Tomcat application running with SSL on port 443. Right now we have an apache server that accepts http requests on port 80 and redirects to the Tomcat instance: <VirtualHost *:80> ServerName domain.com ServerAlias domain.com <LocationMatch "/"> Redirect permanent / https://domain.com/ </LocationMatch> </VirtualHost> Tomcat is handling SSL, because there's no proxy, just a simple redirect to the SSL port: <Connector port="443" maxThreads="200" scheme="https" secure="true" SSLEnabled="true" keystoreFile="/app/ssl/domain_com.jks" keystorePass="ourpassword" clientAuth="false" sslProtocol="TLS"/> We want to begin using the apache web server as a proxy and additionally, do per-IP redirects to certain apps that should only be used by hosts on a pre-determined IP range. We would also like to redirect IPs that don't match the pre-determined list to a static html page hosted on the apache server. My first question is: Should I continue to handle SSL on Tomcat's end, or should I use apache with SSL while forwarding to an "unprotected" tomcat port? Is there any way to redirect to different apps (and potentially hosts) depending on the incoming IP? thanks, del
