• Permissions denied on apache rewrite module virtual host configuration

  - by sina

  All of a sudden I keep getting "Permissions denied" on apache 2 virtualhost once we moved it to its own conf file. I have tried all the suggestions I have found here but none work. Please can someone tell me what I am doing wrong?

• Cisco ASA 5505 (8.05): asymmetrical group-policy filter on an L2L IPSec tunnel

  - by gravyface

  I'm trying to find a way to setup a bi-directional L2L IPSec tunnel, but with differing group-policy filter ACLs for both sides. I have the following filter ACL setup, applied, and working on my tunnel-group: access-list ACME_FILTER extended permit tcp host 10.0.0.254 host 192.168.0.20 eq 22 access-list ACME_FILTER extended permit icmp host 10.0.0.254 host 192.168.0.20 According to the docs, VPN filters are bi-directional, you always specify the remote host first (10.0.0.254), followed by the local host and (optionally) port number, as per the documentation. However, I do not want the remote host to be able to access my local host's TCP port 22 (SSH) because there's no requirement to do so -- there's only a requirement for my host to access the remote host's SFTP server, not vice-versa. But since these filter ACLs are bidirectional, line 1 is also permitting the remote host to access my host's SSH Server. The documentation I'm reading doesn't seem to clear to me if this is possible; help/clarification much appreciated.

• timezone setting per virtual host

  - by garry

  I am trying to test functionality related to timezone handling/conversion during synchronization between two of my test servers (currently they are running on same mashine). Is it possible to set up hosts so one will be running, say, by London time, and the other by Moscow? Web applications running on both servers are written on Perl.

• Middle mouse click in VirtualBox (Vista host, Debian guest)

  - by Ken

  I'm running Virtualbox on Windows Vista. I have a Microsoft USB mouse (it says "Comfort Optical Mouse 3000") with left and right buttons, and a mousewheel in the middle. If I press down on the wheel, it pretty obviously makes a "click". I'm running Debian inside Virtualbox, and it's working great, but middle-mouse-click does nothing. Left and right click, and scrolling with the wheel, work fine. Is there any way to get middle-mouse-click to work in my virtual machine?

• Loading guest OS's (Windows) localhost through my host's (Mountain Lion) browsers

  - by Jonah Goldstein

  For work, I have to develop in Visual Studio, which I run via VMware's fusion 5. I really want to test via my mac's native browsers for a multitude of reasons. that is, view the IIs web stuffs that my windows VM should expose, in my mac's own native Firefox, Chrome... etc. if i could expose a pretty url, that would be even better, but i would certainly settle for an ugly IP :) I got a decent number of views but no response when I asked in VMware's own boards. Everyone seems to want to go the other direction (developing in sublimetext/textmate serving up through MAMP and exposing it to windows browsers to test) and there seems to be tried a true solutions for this. unfortunately (or fortunately depending on your preference) my startup is pretty entrenched in the visual studio development tools. I'm really hoping that someone knows the answer to this. Thanks :)

• Route an IP from WAN to a host on LAN on OpenWRT

  - by Zsub

  EDIT: I know how to use NAT, I specifically want the server to be reachable on two IP's, one private, one public, with the firewall of the OpenWRT in between, if feasible. At the office we have recieved a /29 from our ISP. The first address is reserved for their endpoint, so I'm free to use five addresses. We run a local network, so of course there is a router in between running OpenWRT to provide all hosts with (W)LAN (dhcp from a private range). However, we also have a server running OS X Server 10.6 (Snow Leopard) and I'd like that server to be accessible both from the LAN using a private IP as well as from the WAN on it's own public IP. Point of note is that the server only has one network port, so multiple NICs is not an option, unfortunately. How would I go about doing this?

• Apache Virtual host (SSL) Doc Root issue

  - by Steve Hamber

  I am having issues with the SSL document root of my vhosts configuration. Http sees to work fine and navigates to the root directory and publishes the page fine - DocumentRoot /var/www/html/websites/ssl.domain.co.uk/ (as specified in my vhost config) However, https seems to be looking for files in the main apache document root found further up the httpd.conf file, and is not being overwritten by the vhost config. (I assume that vhost config does overwrite the default doc root?). DocumentRoot: The directory out of which you will serve your documents. By default, all requests are taken from this directory, but symbolic links and aliases may be used to point to other locations. DocumentRoot "/var/www/html/websites/" Here is my config, I am quite a new Linux guy so any advise is appreciated on why this is happening!?

• Plesk 9 - Client panel access via client domain, not server host name

  - by Ben

  I've setup a Plesk 9 vps recently. The plesk admin is accessible at, say, http://superawesomedomain.com:8443. I'm setting up a couple of client domains on the server. I'd like clients to be able to access plesk via a similar url, but instead it would be something like http://inferiorclientdomain.com:8443. This works ok in a sense, but it always redirect the request for inferiorclientdomain.com:8443 to superawesomedomain.com:8443. I'd like the control panel access url to remain on inferiorclientdomain.com. Is that possible? EDIT: System Info. Plesk 9.5.2 on CentOS 5 (Build 95100504.12)

• Can Azure host ColdFusion?

  - by mbursill

  A friend has a site developed in ColdFusion with MySQL and is looking for better cost-effective hosting as the traffic scales up rapidly. Azure comes to mind. I haven't used Azure myself, however, I believe it is possible to setup and interact with the web-server via RDP into a hosted Virtual Machine? I am curious if ColdFusion can be installed in the hosted Azure VM. Also, would the site have to be tweaked to run on Azure SQL, or could it continue to use MySQL? Thanks.

• Configure host access rights in OpenLDAP

  - by Anonymous Coward

  I've set up an OpenLDAP-Server to authenticate users to our Ubuntu-servers. The authentication works quite well but I'd like to restict the user's access to certain servers. I know this can be done through nss_base_something in the client's ldap.conf. However, this requires the group restrictions to be specified on the client. I wonder if the restrictions can be set completely in OpenLDAP. If it is, I'd like to know how. Thanks, AC

• HTTPS request to a specific load-balanced virtual host (using Shibboleth for SSO)?

  - by Gary S. Weaver

  In one environment, we have three servers load balanced that have a single Tomcat instance on each, fronted by two different Apache virtual hosts. Each of those two virtual hosts (served by all three servers) has its own different load balancer. Internally, the first host (we'll call it barfoo) is served by port 443 (HTTPS) with its cert and the second host (we'll call it foobar) is served by port 1443 (HTTPS). When you hit foobar, it goes to the load balancer which is using IP affinity for that host, so you can easily test login/HTTPS on one of the servers serving foobar, but not the others (because you keep getting that server for the lifetime of the LB session, iirc). In addition, each of the servers are using Shibboleth v2 for authN/SSO, using mod_shib (iirc). So, a normal request to foobar hits the LB, is directed to the 3rd server (and will do that from then on for as long as the LB session lasts), then Apache, then to the Shibboleth SP which looks at the request, makes you login via negotiation with the Shibboleth IdP, then you hit Apache again which in turn hits Tomcat, renders, and returns the response. (I'm leaving out some steps there.) We'd like to hit one of the individual servers (foobar-03.acme.org which we'll say has IP 1.2.3.4) via HTTPS (skipping the load balancer), so we at first try putting this in /etc/hosts: 1.2.3.4 foobar.acme.org But since foobar.acme.org is a secondary virtual host running on 1443, it attempts to get barfoo.acme.org rather than foobar.acme.org at port 1443 and see that the cert for barfoo.acme.org is invalid for this case since it doesn't match the request's host, foobar.acme.org. I thought an ssh tunnel might be easy enough, so I tried: ssh -L 7777:foobar-03.acme.org:1443 [email protected] I tried just hitting https://localhost:7777/webappname in a browser, but when the Shibboleth login is over, it again tries to redirect to barfoo.acme.org, which is the default host for 443, and we get into an infinite redirect loop. I then tried setting up an SSH tunnel with privileged port 443 locally going to 443 of foobar-03.acme.org as the hostname for that virtual host: sudo ssh -L 443:foobar-03.acme.org:1443 [email protected] I also edited /etc/hosts to add: 127.0.0.1 foobar.acme.org This finally worked and I was able to get the browser to hit the individual HTTPS host at https://foobar.acme.org/webappname, bypassing the load balancer. This was a bit of a pain and wouldn't work for everyone, due to the requirement to use the local 443 port and ssh to the server. Is there an easier way to browse to and log into an individual host in this case?

• Mongodump on Gridfs is killing the host IOs

  - by Raphael

  I'm trying to make a mongodump from our production mongodb while the production is running. We have three production instances, one regular mongodb, one with very few gb of data on gridfs, one with a larger amount of data on gridfs. All mongodb instances are running in version 2.4.9 on a ubuntu 10.04 virtual server. I use a mongodump command to export the bases to another server. Unfortunately our machines are virtually hosted in a "low performances" datacenter (vmware based) so when I try to export the large gridfs db, the disk IO hits 100% (and 50% of the cpu starts waiting for IO too). This has a very negative impact on the production applicatiosn because db access time is excessively increased, making the applications unusable. I'm looking for a way to regulate the mongodump so the export goes slower but cooler on the hardware ressources allowing better performances for the applications to run. Has anyone had a similar scenario ?

• Host ::1 resolves to remote IP

  - by thebuckst0p

  /etc/hosts files usually have this line, ::1 localhost. I thought ::1 was the equivalent of 127.0.0.1/localhost, and from my reading it seems to be the IPv6 version. So I was using it in Apache for firewalling, "Allow from ::1" and it only allowed local. Then suddenly that stopped working, so I pinged ::1 and got a remote IP address. I tracerouted it and it went through my ISP, through some Microsoft server, then another half dozen steps of asterisks... I'm not sure why this would be (the remote IP), but it doesn't seem good. I grep'd my hard drive for the remote IP and it doesn't appear anywhere. Is this some indicator that I'm being hacked, or normal behavior? Maybe my IPv6 settings are wrong? (This is a brand new MacBookPro with Snow Leopard.) Any ideas about this would be great - what is ::1 supposed to be, why would it be remote, should I be worried, how do I get it back to localhost? Thank you!

• Blocking non-virtual host access in Apache?

  - by cmbrnt

  I'm running an apache-server, with a bunch of virtual hosts for about seven domain names. Now I'd like to disallow access for clients who try to access my server using only its IP-adress. So: When someone accesses my website through www.domain.com, they reach the site hosted in /var/www/domain.com/public_html/. When someone enters the ip-address of the server they reach a 403 Forbidden-message. The problem with this is that they are theoretically able to reach my other sites through bruteforce, when getting http://11.22.33.44/domain.com/public_html/. I rather want them to reach a 403 Forbidden all the time, as long as they don't access my server by a valid domain name. How do I solve this problem?

• Help, my CentOS servers keep going down , No route to host after a random uptime

  - by user249071

  Hello , I have a couple of Centos linux servers, that have a very simple task, they run nginx + fastcgi for php , and some NFS mounts between them, readonly They have some RPC commands to start some downloading processes with wget, nothing fancy , from a main server, but their behavior is very unstable, they simply go down, we tried to monitor ram , processor usage, even network connections, they don't load up so much, max network connections up to... 250 max, 15% processor usage and memory , well, doesn't even fill up, 2.5GB from 8GB max , I have no ideea why can a linux server go down like that, they aren't even public servers, no domain names installed no public serving, for sites. The only thing that I've discovered was that if i didn't restart the network service every couple of hours or so... the servers were becoming very slow, starting apps very slow, but not repoting a high usage of resources...Maybe Centos doesn't free the timeout connections, or something like that...It's based on Red Hat right? I'm not a linux expert , but I'm sure that there are a few guys out there that can easily have an answer to this , or even have some leads to what i can do ... I haven't installed snort, or other things to view if we have some DOS attacks, still the scheduled script that restarts the network each hour should put the system back online, and it doesn't.... Thank you in advance

• CentOS 6.3 Virtual under OpenVZ cannot ping, host lookups, outbound connections while postfix running

  - by Paul Cravey

  My best theory is that some kernel limit is being hit preventing outbound connections. We have tried basically everything from tcpdumps to provisioning an entirely new virtual server (we do not have this problem on any other virtuals), however the problem somehow carried over, even with new postfix build (working). Emails work, and outbound connections work, so long as postfix does not have too much going on. /proc/user_beancounters shows no limits being hit (show below). Nevertheless, pings fail even to IP addresses. TCP stack appears healthy. Load is low. No iowait. Flushed iptables already. Has anyone experienced anything like this? uid resource held maxheld barrier limit failcnt 3: kmemsize 166216365 170262528 9223372036854775807 9223372036854775807 0 lockedpages 0 0 9223372036854775807 9223372036854775807 0 privvmpages 285727 351885 9223372036854775807 9223372036854775807 0 shmpages 16933 17605 9223372036854775807 9223372036854775807 0 dummy 0 0 0 0 0 numproc 150 303 9223372036854775807 9223372036854775807 0 physpages 314156 326191 0 1280000 0 vmguarpages 0 0 9223372036854775807 9223372036854775807 0 oomguarpages 165355 165355 9223372036854775807 9223372036854775807 0 numtcpsock 89 172 9223372036854775807 9223372036854775807 0 numflock 22 76 9223372036854775807 9223372036854775807 0 numpty 1 2 9223372036854775807 9223372036854775807 0 numsiginfo 0 75 9223372036854775807 9223372036854775807 0 tcpsndbuf 2733472 4371752 9223372036854775807 9223372036854775807 0 tcprcvbuf 1798336 5427296 9223372036854775807 9223372036854775807 0 othersockbuf 491120 1000760 9223372036854775807 9223372036854775807 0 dgramrcvbuf 0 238728 9223372036854775807 9223372036854775807 0 numothersock 361 505 9223372036854775807 9223372036854775807 0 dcachesize 135941831 136114679 9223372036854775807 9223372036854775807 0 numfile 2905 4990 9223372036854775807 9223372036854775807 0 dummy 0 0 0 0 0 dummy 0 0 0 0 0 dummy 0 0 0 0 0 numiptent 8 9 9223372036854775807 9223372036854775807 0 [root@bni /]# ping 4.2.2.1 PING 4.2.2.1 (4.2.2.1) 56(84) bytes of data. --- 4.2.2.1 ping statistics --- 9 packets transmitted, 0 received, 100% packet loss, time 8493ms [root@bni /]# service postfix stop [root@bni /]# ping 4.2.2.1 PING 4.2.2.1 (4.2.2.1) 56(84) bytes of data. 64 bytes from 4.2.2.1: icmp_seq=1 ttl=53 time=8.63 ms 64 bytes from 4.2.2.1: icmp_seq=2 ttl=53 time=8.62 ms 64 bytes from 4.2.2.1: icmp_seq=3 ttl=53 time=8.63 ms 64 bytes from 4.2.2.1: icmp_seq=4 ttl=53 time=8.66 ms Outbound connections of all sorts fail when postfix is running.

• timeout with apache & php w/ each virtual host has his own user process

  - by acemtp

  I have 10 unix users in /home/. Each user is for a specific subdomain for example user www in /home/www/public_html is for www.mywebsite. blog in /home/blog/public_html is for blog.mywebsite. 90% is php and 10% ror for the moment i use apache + fastcgi that use SuexecUserGroup to setup the process with the good user. it seems to works but i have a strange behavior where after a few hours/days, the server stop answering (timeout) but the cpu load is still very low (it's a big server), the apache status display lot of "W" Sending Reply states but there's still 50 idle workers so it should be able to answer. in the older server (lot of slower) we add only one user and using mod_php and we never had this issue. is there another way to do that without fastcgi and SuexecUserGroup or do you know what's going wrong?

• Host hijacks USB printer from VirtualBox machine

  - by jackhab

  I have Ubuntu 9.1 running Windows XP in VirtualBox. Windows XP is a print server (there is no Linux driver for our printer). The printer is connected via USB and its USB filter is added to virtual machine settings. The problem is that every several hours Ubuntu tries to access the printer (trying to install it) and disconnects it from the virtual machine. The printer remains disconnected until I connect it again manually. I thought it is a problem with Windows power management but disabling sleep/standby in Windows didn't help. Please, advise.

  - by tipu

  I have a VM Ware player, VMware-player-3.0.1-227600.exe I downloaded a cent os image, it's version is CentOS release 5.4 (Final) I have apache installed and listening on port 8080. However when I visit my ip address, x.x.x.x.:8080/ I don't get the default apache page as I would by going to localhost:8080/ What do I have to do in my image or vmware to get it to serve?

• VirtualPC/XPMode... trying to let a VM access pages served using IIS on the host machine

  - by John

  My host PC is running IIS7.5 under Windows7. I have a VM running XP to let me use IE6, but I've no idea what network settings on the VM/host are needed so the VM can access pages on the host. I thought if the host was 192.168.1.1, then from the VM I'd simply do http://192.168.1.1/... if I do this on the host it works but the VM can't see it. I'm assuming there are some shortcuts here rather than manually having to set up loads of permissions, e.g a shortcut way of letting the VM access the host maybe?

• IPTABLE & IP-routed netwok solution for HOST net and VM's subnet

  - by Daniel

  I've got ProxmoxVE2.1 ruled KVM node on Debian and bunch of VM's guests machine. That is how my networking looks like: # network interface settings auto lo iface lo inet loopback # device: eth0 auto eth0 iface eth0 inet static address 175.219.59.209 gateway 175.219.59.193 netmask 255.255.255.224 post-up echo 1 > /proc/sys/net/ipv4/conf/eth0/proxy_arp And I've got two working subnet solution auto vmbr0 iface vmbr0 inet static address 10.10.0.1 netmask 255.255.0.0 bridge_ports none bridge_stp off bridge_fd 0 post-up ip route add 10.10.0.1/24 dev vmbr0 This way I can reach internet, to resolve outside hosts, update and download everything I need but can't reach one guest VM out of any other VM's inside my network. The second solution allows me to communicate between VM's: auto vmbr1 iface vmbr1 inet static address 10.10.0.1 netmask 255.255.255.0 bridge_ports none bridge_stp off bridge_fd 0 post-up echo 1 > /proc/sys/net/ipv4/ip_forward post-up iptables -t nat -A POSTROUTING -s '10.10.0.0/24' -o vmbr1 -j MASQUERADE post-down iptables -t nat -D POSTROUTING -s '10.10.0.0/24' -o vmbr1 -j MASQUERADE I can even NAT internal addresses: -t nat -I PREROUTING -p tcp --dport 789 -j DNAT --to-destination 10.10.0.220:345 My inexperienced mind is ready to double VM's net adapters: one for the first solution and another - for second (with slightly different adresses) but I'm pretty sure that it's a dumb way to resolve the problem and everything can be resolved via iptables/ip route rules that I can't create. I've tried a dozen of "wizard manuals" and "howto's" to mix both solution but without success. Looking for an advice (and good reading links for networking begginers).
