• Format & Fresh Install Mac os x snow leopard in mac mini.

  - by sagar

  Hello Every one. I have purchased dvd of Snow leopard 10.6.2. But actually I purchased mac mini with 10.5.7 leopard I tried to install snow leopard 10.6.2. Everything went perfectly. system was installed successfully. But the problem that I faced is as follows. System was installed but my older data remained as it is. ( means installation didn't format every thing - means installation was done on upgrade basis. ) Now, my system works with very low speed. Previous performance of mac mini was double as compare to current upgrade version. Now - my question are as follows. Does upgrade installation causes the performance in specially osx ? ( means anyone faced this kind of problem ? ) Or 10.6.2 snow leopard is heavy weight system for mac mini ? ( 2Ghz Intel core2duo,1GB RAM - is this configuration OK for snow leopard 10.6.2 ? ) Fresh install works better then upgrade in os x ?

• "Windows cannot find" file when opening Excel spreadsheet

  - by DanH

  For all of my Excel spreadsheets when I attempt to open them (by double-clicking in explorer) I get the message "Windows cannot find C:...". The files are there, and are valid zip files as seen by 7-Zip. There are no apparent lock files in the directories. I did just install Norton-360 over the weekend (replacing Kasperski), but the Norton log shows no events related to Excel. However, while installing Norton I did reboot with some Excel files open. Presumably something is hosed in my Excel configuration but I don't know what. Update (Before actually posting) -- I found an article that suggested turning off Advanced Option "Ignore other applications that use DDE", then doing excel.exe /unregister followed by excel.exe /register. I tried this but I suspect that the two Excel calls were ignored (Excel opened, but no obvious change). With that option off the spreadsheets load OK, but not with it on. And, curiously, spreadsheets load OK with the option on or off if I open Excel first and then open the spreadsheet in it. Does anyone have any idea what effect leaving that option off will have? Update 2 -- I tried running the "repair" option. It said it corrected a couple of config things (without saying what they were), but I still get a failure if I double-click an Excel file with the "Ignore other applications..." option checked. Update 3 -- I managed to fix this problem, but failed at the time to come back and say what I did, and now I can't remember for sure. But I think it had something to do with "Options"/"Save" and some of the values there. Something to do with AutoRecover, perhaps. (Possibly there was a file in recovery and I had to specify "Disable AutoRecover for this workbook" to let bring-up get past it. Or perhaps the AutoRecover file location was hosed.) Anyway, if it happens to someone else, and you find the fix, post it below and I'll mark it answered.

• KVM guest VLAN aware problems

  - by baraka

  Hi, We are using Centos 5.5. as KVM host. It has two nics. One for management and the other one for services. As we have services in multiple vlans this nic is configured as a 802.1Q trunk. Any VM must be able to have access to any vlan, so host trunk interface is bridged to its tap interface and vlan is configured inside VM. Everything works fine while there is not heavy traffic. I can not find any log on guest or host, but, after some certain sustained big file transfer (about 6Gb) bridging stop working. Other guest on the same host continue working without problems. tcpdump on bridge interface is Ok, but on guest tap inferface I can see only outgoing traffic. Restarting bridge or rejoining tap interface doesn't provide any clue. Rebooting guest turns on bridge again. Bridge configuration is minimal: just addbr and addif (no stp). Any idea welcome!

• How to prioritize openvpn traffic?

  - by aditsu

  I have an openvpn server, with one network interface. VPN traffic is extremely slow. I tried to do traffic control with this configuration (currently): qdisc del dev eth0 root qdisc add dev eth0 root handle 1: htb default 12 class add dev eth0 parent 1: classid 1:1 htb rate 900mbit #vpn class add dev eth0 parent 1:1 classid 1:10 htb rate 1500kbit ceil 3000kbit prio 1 #local net class add dev eth0 parent 1:1 classid 1:11 htb rate 10mbit ceil 900mbit prio 2 #other class add dev eth0 parent 1:1 classid 1:12 htb rate 500kbit ceil 1000kbit prio 2 filter add dev eth0 protocol ip parent 1:0 prio 1 u32 match ip sport 1194 0xffff flowid 1:10 filter add dev eth0 protocol ip parent 1:0 prio 2 u32 match ip dst 192.168.10.0/24 flowid 1:11 qdisc add dev eth0 parent 1:10 handle 10: sfq perturb 10 qdisc add dev eth0 parent 1:11 handle 11: sfq perturb 10 qdisc add dev eth0 parent 1:12 handle 12: sfq perturb 10 But it's still extremely slow. I have an imaps connection that keeps transferring data continuously (I successfully limited the rate) but with openvpn I can't seem to get more than about 100kbit/s The internet connection speed is about 3mbit/s (symmetric) What could be the problem? Does the sport filter work for udp?

• Problem with diacritics on psql 9.0 (PostgreSQL)

  - by Gaks

  I have two instances of PostgreSQL installed on my server: 8.3 and 9.0. There seams to be some problem with Polish diacritic characters (like óleaszzc) on postgresql 9.0 client - psql. When I connect to DB (either 8.3 or 9.0) with psql 8.3 - I can type all diacritics on the terminal without any problems: www:/tmp# sudo -u postgres /usr/lib/postgresql/8.3/bin/psql -q postgres=# ólscn However, when I connect to the same DBs with psql 9.0 client - I can't type diacritics on the terminal anymore: www:/tmp# sudo -u postgres /usr/lib/postgresql/8.3/bin/psql -q Here are some encoding settings: www:/tmp# sudo -u postgres /usr/lib/postgresql/9.0/bin/psql -q -c "show client_encoding" client_encoding ----------------- UTF8 (1 row) . www:/tmp# sudo -u postgres /usr/lib/postgresql/8.3/bin/psql -q -c "show client_encoding" client_encoding ----------------- UTF8 (1 row) . www:/tmp# sudo -u postgres /usr/lib/postgresql/9.0/bin/psql -q -l List of databases Name | Owner | Encoding | Collation | Ctype | Access privileges ---------------------+--------------+----------+-------------+-------------+----------------------- postgres | postgres | UTF8 | pl_PL.UTF-8 | pl_PL.UTF-8 | . www:/tmp# echo $LANG pl_PL.UTF-8 It looks like DB/cluster configuration doesn't matter - if psql 8.x on terminal works fine and psql 9.x does not. Any idea how to fix that?

• Leopard mail.app quoted-printable weirdness

  - by pehrs

  I am not sure if this is a bug in mail.app, or a configuration I just can't find. It might also be a strange sideffect of GPGmail. Mail.app correctly displays all e-mails on my IMAP server, except for the e-mails in my "Sent Messages" folder. In the sent messages folder it messes up åäö, in typical quoted-printable with wrong char-set fashion. They become ‰ˆ. When looking at the source of the e-mails it seems like the header generated by mail.app is correct: Message-Id: <> From: To: In-Reply-To: <> Content-Type: multipart/signed; protocol="application/pgp-signature"; micalg=pgp-sha1; boundary="Apple-Mail-4--741321197" X-Smtp-Server: smtp.example.com Content-Transfer-Encoding: 7bit Mime-Version: 1.0 (Apple Message framework v936) Subject: Example subject Date: Fri, 26 Mar 2010 10:14:14 +0100 References: <> X-Pgp-Agent: GPGMail 1.2.0 (v56) This is an OpenPGP/MIME signed message (RFC 2440 and 3156) --Apple-Mail-4--741321197 Content-Type: text/plain; charset=ISO-8859-1; format=flowed; delsp=yes Content-Transfer-Encoding: quoted-printable <Text here with =E5=E4=F6> --Apple-Mail-4--741321197 content-type: application/pgp-signature; x-mac-type=70674453; name=PGP.sig content-description: This is a digitally signed message part content-disposition: inline; filename=PGP.sig content-transfer-encoding: 7bit -----BEGIN PGP SIGNATURE----- Version: GnuPG/MacGPG2 v2.0.12 (Darwin) iEYEARECAAYFAkus62kACgkQlIRLofxhDjYnnwCcDmCXuMGsKlh3a418s12coJgn 36sAoKMdkP3+g/OMK+Ps7AbjQq4Nbqzv =XMko -----END PGP SIGNATURE----- --Apple-Mail-4--741321197-- Thunderbird has no problem displaying the messages.

• Is there a way to determine which service (in svchost.exe) does an outgoing connection?

  - by fluxtendu

  I'm redoing my firewall configuration with more restrictive policies and I would like to determine the provenance (and/or destination) of some outgoing connections. I have an issue because they come from svchost.exe and go to web content/application delivery providers - or similar: 5 IP in range: 82.96.58.0 - 82.96.58.255 --> Akamai Technologies akamaitechnologies.com 3 IP in range: 93.150.110.0 - 93.158.111.255 --> Akamai Technologies akamaitechnologies.com 2 IP in range: 87.248.194.0 - 87.248.223.255 --> LLNW Europe 2 llnw.net 205.234.175.175 --> CacheNetworks, Inc. cachefly.net 188.121.36.239 --> Go Daddy Netherlands B.V. secureserver.net So is it possible to know which service does a particular connection? Or what's your recommendation about the rules applied to these ones? (Comodo Firewall & Windows 7) Update: netstat -ano & tasklist /svc help me a little but they are many services in one svchost.exe so it's still an issue. moreover the service names returned by "tasklist /svc" are not easy readable. (All the connections are HTTP (port 80) but I don't think it's relevant)

• How can I avoid an error in this .htaccess file?

  - by mipadi

  I have a blog. The blog is stored under the /blog/ prefix on my website. It has the usual URLs for a blog, so articles have URLs in the format /blog/:year/:month/:day/:title/. First and foremost, I want to automatically redirect visitors to the www subdomain (in case they leave that off), and internally rewrite the root URL to /blog/, so that the front page of the blog appears on the front page of the site. I have accomplished that with the following set of rewrite rules in my .htaccess file: RewriteEngine On # Rewrite monkey-robot.com to www.monkey-robot.com RewriteCond %{HTTP_HOST} ^monkey-robot\.com$ RewriteRule ^(.*)$ http://www.monkey-robot.com/$1 [R=301,L] RewriteRule ^$ /blog/ [L] RewriteRule ^feeds/blog/?$ /feeds/blog/atom.xml [L] That works fine. The problem is that the front page of the blog now appears at two distinct URLs: / and /blog/. So I'd like to redirect the /blog/ URL to the root URL. Initially I tried to accomplish this with the following set of rewrite rules: RewriteEngine On # Rewrite monkey-robot.com to www.monkey-robot.com RewriteCond %{HTTP_HOST} ^monkey-robot\.com$ RewriteRule ^(.*)$ http://www.monkey-robot.com/$1 [R=301,L] RewriteRule ^$ /blog/ [L] RewriteRule ^blog/?$ / [R,L] RewriteRule ^feeds/blog/?$ /feeds/blog/atom.xml [L] But that gave me an infinite redirect (maybe because of the preceding rule?). So then I tried this set: RewriteEngine On # Rewrite monkey-robot.com to www.monkey-robot.com RewriteCond %{HTTP_HOST} ^monkey-robot\.com$ RewriteRule ^(.*)$ http://www.monkey-robot.com/$1 [R=301,L] RewriteRule ^$ /blog/ [L] RewriteRule ^blog/?$ http://www.monkey-robot.com/ [R,L] RewriteRule ^feeds/blog/?$ /feeds/blog/atom.xml [L] But I got a 500 Internal Server Error with the following log message: Invalid command '[R,L]', perhaps misspelled or defined by a module not included in the server configuration What gives? I don't think [R,L] is a syntax error.

• No OS will boot, all freeze

  - by Gyan

  This is for a computer with the following configuration: Asus P5KPL-AM/PS motherboard Pentium D 820 (dual core 2.8 GHz) 1 x 2 GB DDR2-800 Transcend RAM 1 SATA2 Samsung 160 GB HDD 1 PATA LG CD/DVD Writer PS/2 generic Keyboard USB Razer mouse The computer was working fine till a month ago with a Hitachi HDD in place of the Samsung. But that drive died and I sent it in for warranty replacement. Since then and till last week, the computer had not been turned on. I then got hold of a spare but XPSP2-loaded Samsung drive from another computer and decided to get this computer temporarily running. However, when I tried to boot into XP, it didn't load. It got stuck at the first graphical screen. When trying Safe Mode, the file list would be updated up to diskio.sys and then freeze. If I tried to boot Kubuntu off a CD, I would get past the first menu, but then get stuck at the subsequent graphical interface in the loading process. A similar thing happend with a friend's Windows XP-on-a-pen-drive. I switched the RAM into the other slot, but no luck. Then I booted the Ultimate Boot CD and ran Memtest86+ and a couple of the bundled CPU stress tests but these detected no errors. Some searching on the Internet brought up the notion of the CPU failing to switch from "real" to "protected mode". I'm hoping to get a fix on what the problem is and what I can do about it. Edit: I've flashed to the latest BIOS, but that doesn't help. Also, Knoppix LiveCD also freezes. I notice that the LED in my mouse goes off at the time of freeze, but trying to boot without the mouse connected produces the same result.

• Spotlight actually searching every file on "This Mac"

  - by Cawas

  I know of 2 ways to search for any file in your machine using Finder (some say it's Spotlight) and no Terminal. To prevent answers / comments about Terminal, I consider it either for scripting something or as last resource. It's not practical for lots of usages. For instance, if you want to find something to attach to a mail, or embed in iTunes or any other app, you can just drag n' drop one or many of them. Definitely not practical to do under Terminal. There are many cases of use for any, but the focus here is Graphical User Interface. Well, the 2 ways basically are: Press Cmd + Opt + Spacebar and type in your search. Press the + button, select "System files" and "are included". This is so far my preferred way, but I'm not sure it will go through every file. Open Finder, press Cmd + Shift + G and/or select just one folder. Type in your search and select the folder rather than "This Mac". This will bring files not shown in "This Mac" if you select a folder outside of the default scope. Thing is, none of those is really convenient or have the nice presentation from regular Spotlight, which you get from Cmd + Spacebar and just typing. And, as far as I've heard, the default behavior on Spotlight in Tiger was actually being able to find files anywhere. So, is there any way to make the process significantly simpler? Maybe some tweak, configuration or really good Spotlight alternative? I'd rather keep it simple and tweak Spotlight.

• Router failover not detecting outside interface link lost

  - by Matt

  Suppose I have two routers configured in master/slave configuration. They look something like this (addresses are not real ones) 123.123.123.10 <===> [eth0] Router 1 (10.1.1.2) [eth1] ===> +----------+ | 10.1.1.1 | ===> LAN 172.123.123.10 <===> [eth0] Router 2 (10.1.1.3) [eth1] ===> +----------+ The 10.1.1.1 is the default route for the Network (10.1.1.0). What's slightly different in this config to other's I've seen is that I don't have an external virtual IP. Also, the 10.1.1.1 addresses are in real life, public IP's (not private ones shown here). This is more of a router setup than a firewall setup so I'm not using NAT here. Now the issue that I'm having is that I can't see any way to configure UCARP or VRRP to monitor both eth0 & eth1 and fail over to the backup router should either of them go down. What I'm seeing is that if Router1 is the master and I unplug eth0 on router1, it doesn't fail over to router 2. However, it will if instead I unplug eth1 of router 1. In VRRP I see there is a cluster group, but it seems that for this to work you need to have virtual ip's or vrrp instances rather than actual interfaces assigned to it. I hope my explanation is clear. How do I get around this?

• Debian software raid 1: boot from both disk

  - by bsreekanth

  I newly installed debian squeeze with software raid.The way I did was, as also given in this thread. I have 2 HDD with 500 GB each. For each of them, I created 3 partitions (/boot, / and swap) I selected the hard drive and created a new partition table I created a new partition that was 1GB. I then specified to use the partition as a Physical Volume for RAID. and used for /boot and enabled bootable. Created another partition, which is of 480 GB, and then specified to use the partition as a Physical Volume for RAID. and used for /. Created another partion and used for swap Then RAID configuration: Through Configure RAID menu - create MD device - (2 for the number of drives, 0 for spare devices) Next select the partitions you want to be members of /dev/MD0. I selected /dev/sda1 and /dev/sdb1 (for /boot) Next select the partitions you want to be members of /dev/MD1. I selected /dev/sda6 and /dev/sdb6 (for /) And no RAID for swap partitions 'Finish Partitioning and write changes to disk' -- Finish the rest of the install like normal Everything is ok now, except I am not sure how to test my raid config. When I pull the power of the HDD, it only boots from one disk. I read in some forum that I may have to install GRUB manually on the other. In Debian Squeeze, there is no grub command. Not sure how to make my software raid bootable from both disk. Also, please comment on my steps above. Anything unusual. I configured /boot partitions of both disks to be boot=yes. Not sure whether that is ok. Thanks, Bsr

• Datacenter IP Addressing and DNS Management

  - by user65248

  Hello everyone Basically we are setting up a small Datacenter, about 300 amps power and max 50 racks, Im saying these coz I wanna u imagine the size and requirements, I have studied networking mostly Microsoft and Windows based systems , but I cant get how the IP addressing and DNS management and configuration works in a Datacenter , and unfortunately I have to setup everything by myself but defe we will have some staff to do some job. Now my questions Datacenter IP Addressing Suppose we have got a block of 200 IP addresses from our ISP, How can I manage these block of IP addresses, is there any software out there to simplify this I heard that using DHCP server in a datacenter is not recommended, otherwise what would u say about MS DHCL server ofc considering we need to have backup serversin case of failur How can I assign a block of IPs to a specific rack, I know with different software and management its different but Im asking how it is done normally IP addresses are exposed to the whole network, what if a customer try to use an IP address and is not assigned to their server or rack , how can I prevent this or how can I track the IP usage DNS Management Im goin to setup at least two servers for our DNS servers, I know nothing about Datacenter DNS system, but I have configured DNS server in normal networks and also for webservers, Now I wanna know What exactly needs to be done for a DNS in a datacenter that is not done for normal networks. How can I configure PTR records why cant I configure PTR records on my webserver side DNS server and it should be done on datacenter DNS server , I mean what is the difference in DC DNS servers that allow us to to so , I know the question is very silly and simple but Im confused Is there any software outthere to allow doing the whole thing, I mean automatically add records to the DNS and also managin IP addresses !? Thanks in advance

• Moving Farm to co-location hosting - network settings requirements

  - by Saariko

  I am moving my farm (2 Dell's R620) to a co-location hosting service. I am trying to figure out the secure way to have my network settings The requirements are: VM1 is the working HOST, includes: esxi 5.1, vSphere, 4 clients (w2008r2 all) VM2 has esxi 5.1 installed, and a single machine with Veeam Backup and copy 6.5 - keeping a copy of VM1 clients on the VM2 internal storage (this solution is due to a very small budget - in case of failure on Host 1 - can redirect IP's) Only 2 VM clients require network address and access from the WWAN - ISP provides IP's range for them (with Gateway and DNS) I need connection to the iDrac's from my office (option to create a VPN-SSL tunnel) Connection to the vSphere appliances I want to be able to RDP to the VM clients The current configuration is that each host has the iDrac dedicated nic connected , and another (NIC #1) connected - with a static IP on 192.168.3.x The iDrac's have a static IP from the same network range (19.168.3.x) It will look something like this: My thoughts: On NIC#2 of both hosts I will connected a crossed cable I will give each VM clients that needs internet access a 2ndry VM network with the assigned IP from the ISP open only to web - can not access from the My Question: Should I give IP's (external) to the machines who DO NOT require WWAN Access? - I can't see a way to RDP to them directly if not. Should I use the crossed cable? or just plug NIC #2 to the switch? Will this setup even work? What do I need to verify? What Virtual nic's and/or switches should I create on the Hosts?

• Apache Reverse proxy for intranet and other integrated application on intranet

  - by user1433448

  I'm trying to configure a reverse proxy (ssl) with apache 2.2 in Debian Squeeze, but I have some problems, specially with some path absolute and with https I'll try to detail what I have made and what I'm trying to configure I have a server Debian Squeeze with apache2.2 + mod_proxy_html with: # apt-get install libapache2-mod-proxy-html libxml2-dev # a2enmod proxy # a2enmod proxy_http # a2enmod proxy_html # a2enmod headers After that I have configured a virtual host with: reverse_proxy_ssl.conf I'm trying to configure to allow access of our intranet from internet with a reverse proxy (apache that is located in DMZ). With this configuration domain.com/intranet works correctly and we can access to intranet, but we have one problem when from domain.com/intranet we need to use another internal application that is called from intranet with absolute path ( https://192.168.10.25/application/) and from internet appears that try to access with internal ip, and this link es incorrect from external site We only need to access from intranet to multiple internal application that are in external server and we like to restrict to minimal access from internet. All the application that are in the smae server of intranet are working. The second problem is with https and reverse proxy in our firewall appears some errors with packets (not valid packets), and with https seems to work. What can I do to solve this problems (absolute path and ssl problem) Thanks

• How can I tell GoogleBot that a subdirectory is now a subdomain? [migrated]

  - by cwd

  I had about a million pages of a catalog indexed under a subdirectory, and now that's moved to a subdomain. GoogleBot is crawling each one of them and getting a 301 redirect to the new location. Even though I have set up the redirect rule in the apache sites-enabled configuration file, (i.e. it's early on when apache does the redirect - PHP is not even getting loaded), even though I have done that, the server isn't handling the load well. GoogleBot is making around 5 requests per second, and on top of my normal traffic that is hiking up the CPU for a few hours at a time. I checked in Webmaster Tools and the corresponding documentation for a way to let Google know that the content had been moved from a subdirectory to a subdomain, but with little luck. Basically the most helpful thing I saw said to just send 301 headers for the new location. How can I tell GoogleBot that a subdirectory is now a subdomain? If that is not an option, how can I more efficiently send 301 redirects out for a particular subdomain? I was thinking perhaps the Nginx server but I'm not sure that I can run both Apache and Nginx side by side on port 80 for different subdomains.

• Vista gets stuck in an endless loop while booting

  - by Mason Wheeler

  I put my laptop to sleep last night, and when I woke up this morning... it didn't. So I tried to reboot, and everything went fine until it got to the Vista splash screen, where it's supposed to display the logon. Here, it hits an endless loop: Display the cursor with the blue spinny thing that replaced the hourglass, for 5-10 seconds Display "Please wait..." for about half a second Screen flashes to black, then quickly back to the Vista splash screen Goto step 1 The whole time, my hard LED is on almost non-stop. I can boot into Safe Mode... sometimes. Sometimes it'll load all the drivers, then sit there for about 10 minutes, spinning the hard drive non-stop, then reboot with no warning. I tried booting to Last Known Good Configuration. Didn't fix anything. When I've managed to get into Safe Mode, I tried running CHKDSK. Didn't fix anything. I tried running System Restore to each of my last two restore points. Didn't fix anything either time. I ran a virus scan. Didn't find anything. I tried calling the manufacturer (Alienware), only to discover that my warranty expired last freaking week and now I can't get it fixed without paying exorbitant sums of money. I'm about at my wits' end here. Has anyone seen this problem before? Does anyone know how to fix it? Does anyone know a solution that does not involve reinstalling the OS and losing an entire year's worth of program installations, Windows Updates and configuring and tweaking things until it's working just like I want it to?

• Network Explorer Intermittently Fails to Display all Computers in Work Group

  - by graf_ignotiev

  I run a small computer lab of 10 computers and occasionally, when using the network explorer (a.k.a Network Browser) some or all of the remote computers will fail to appear. If I try to access a remote computer by its name I get an unspecified error (code 0x80004005), but I am still able to access it with the computer's IP address. The strangest part is that the problem will inexplicably go away after waiting awhile. Each computer is running Windows 7 x64 Enterprise and has identical hardware, software and configuration. They are all on the same subnet and in the same workgroup. I've spent days researching the problem and have tried the following solutions: Updated the BIOS, chipset and network adapter drivers Changed Power Settings in Network Adapter Properties so that the computer will not turn it off Disabled the Computer Browser service Changed the DHCP node type to broadcast Reviewed the Event Viewer logs Steps 3 and 4 have seemed to help the problem a little bit, but not completely. I'm beginning to suspect that the problem might lie with our router which is a ZyXEL ZyWALL 2WG, as the packets sent by Network Discovery may not be returning in time, but I wanted to get some perspective in the issue before I went any further.

• apache name virtual host - two domains and SSL

  - by Tom

  I'm trying to setup Apache(2.2.3) to run two websites with SSL using both different domains and IP addresses. Both websites run fine on port 80 but when I tried to enable SSL for website2 I get a ssl_error_bad_cert_domain error; website2 picks up the SSL cert for website1. Here is my setup in httpd.conf: # Website1 NameVirtualHost 192.168.10.1:80 <VirtualHost 192.168.10.1:80> DocumentRoot /var/www/html ServerName www.website1.org </VirtualHost> NameVirtualHost 192.168.10.1:443 <VirtualHost 192.168.10.1:443> SSLEngine On SSLCertificateFile conf/ssl/website1.cer SSLCertificateKeyFile conf/ssl/website1.key </VirtualHost> # Website2 NameVirtualHost 192.168.10.2:80 <VirtualHost 192.168.10.2:80> DocumentRoot /var/www/html/chart ServerName www.website2.org </VirtualHost> NameVirtualHost 192.168.10.2:443 <VirtualHost 192.168.10.2:443> SSLEngine On SSLCertificateFile conf/ssl/website2.cer SSLCertificateKeyFile conf/ssl/website2.key </VirtualHost> Update: In answer to Shane (this wouldn't fit in comment box) here is the output from apachectl -S: VirtualHost configuration: 192.168.10.2:80 is a NameVirtualHost default server www.website2.org (/etc/httpd/conf/httpd.conf:1033) port 80 namevhost www.website2.org (/etc/httpd/conf/httpd.conf:1033) 192.168.10.2:443 is a NameVirtualHost default server bogus_host_without_reverse_dns (/etc/httpd/conf/httpd.conf:1040) port 443 namevhost bogus_host_without_reverse_dns (/etc/httpd/conf/httpd.conf:1040) 192.168.10.1:80 is a NameVirtualHost default server www.website1.org (/etc/httpd/conf/httpd.conf:1017) port 80 namevhost www.website1.org (/etc/httpd/conf/httpd.conf:1017) 192.168.10.1:443 is a NameVirtualHost default server bogus_host_without_reverse_dns (/etc/httpd/conf/httpd.conf:1024) port 443 namevhost bogus_host_without_reverse_dns (/etc/httpd/conf/httpd.conf:1024) wildcard NameVirtualHosts and _default_ servers: _default_:443 192.168.10.1 (/etc/httpd/conf.d/ssl.conf:81) Syntax OK

• Accounting setup in freeradius with mikrotik and the "always" module

  - by Matt

  I have a freeradius setup that is being used to provide authentication for users on a wireless network. The access points are all Mikrotik hardware and the users are connected 24/7. We've been using Daloradius with mysql and freeradius 2. The boss wants to use the accounting information and while this is all set up and appears to be working, I've found that not all the accounting information is present. Since our users may be connected for more than 24 hours at a time we keep this in here, it will reset some attributes daily so that the accounting packets work correctly. So he started poking around at this link: http://wiki.mikrotik.com/wiki/RouterOs_MySql_Freeradius#Configuring_RouterOs_for_Radius_.26_PPP.2A_AAA And was looking specifically at the following section. Since our users may be connected for more than 24 hours at a time we keep this in here, it will reset some attributes daily so that the accounting packets work correctly always fail { rcode = fail } always reject { rcode = reject } always ok { rcode = ok simulcount = 0 mpp = no } However, that link references freeradius 1 and I can't find this in the radius.conf file for freeradius 2. What does it do and could it be a reason I'm missing data? EDIT: I have found one issue. We have a backup freeradius server that is also receiving the accounting packets. Although they are replicating, it's only a master/slave configuration. If the slave receives accounting packets it won't replicate them back to the master. Although I suspect this might solve it, the boss is not convinced due to the always module. Is there anything special I need to configure in the mikrotik AP's or freeradius 2 for clients connected 24/7.

• Name resolution not working with ipv6 on centos

  - by jolivier

  I just installed CentOs 6.3 on a server to be installed in a data center, but cannot get name resolution / curl to work. I know this is because of it trying to use ipv6, since ping google.com works, curl -4 google.com works, but not curl google.com. I removed the ipv6 adress from the interface and it does not change anything. This is very problematic since most system tools like yum fail at name resolution currently. Browsers like Firefox work because they might be using another tool for name resolution than the one use by curl. I managed to fix this on workstations by completely disabling ipv6 following tutorials like this one / hardcoding name resolution in /etc/hosts. But since I am here configuring a server which will be later installed in a remote data center, I would like not to mess up, understand what is going on and fix it properly. Besides, I will face the same issue with more servers to come so I would really appreciate your help in understanding this problem and how to solve it. I would be happy to provide more information if needed to help understand what is going on. The current network configuration is a small enterprise network, with a DNS server (let's call it A) configured once a long time ago. dig google.com and dig -4 google.com are both refused by the A DNS. But this is also true for my workstation on which curl is working (and yes they both use the same A DNS server). Indeed this faulty server and my workstation have multiple nameservers in /etc/resolv.conf, and the second one is working fine for both of them, so if I remove A from my resolv.conf everything works fine!

• Why I am getting "Problem loading the page" after enabling HTTPS for Apache on Windows 7?

  - by Anish

  I enabled HTTPS on the Apache server (2.2.15) Windows 7 Enterprise by uncommenting: Include /private/etc/apache2/extra/httpd-ssl.conf in C:\Program Files (x86)\Apache Software Foundation\Apache2.2\conf\httpd.conf and modifying C:\Program Files (x86)\Apache Software Foundation\Apache2.2\conf\httpd-ssl.conf to include: DocumentRoot "C:/Program Files (x86)/Apache Software Foundation/Apache2.2/htdocs" ServerName myserver.com:443 ServerAdmin [email protected] ... SSLCertificateFile "SSLCertificateFile "C:/Program Files (x86)/Apache Software Foundation/Apache2.2/conf/cert.pem SSLCertificateKeyFile "SSLCertificateFile "C:/Program Files (x86)/Apache Software Foundation/Apache2.2/conf/key.pem" Then I restart apache (going to start-All Progranms-Apache Server 2.2-Control-restart) and go to localhost on port 443 in Firefox , where I get: Index of / Index of / Links/ ..... .... But on Display of WebPage I see: Unable to connect Firefox can't establish a connection to the server at localhost. *The site could be temporarily unavailable or too busy. Try again in a few moments. *If you are unable to load any pages, check your computer's network onnection. *If your computer or network is protected by a firewall or proxy, make sure that Firefox is permitted to access the Web. I read: Why am I getting 403 Forbidden after enabling HTTPS for Apache on Mac OS X? and added default web server configuration block to match my DocumentRoot The error Log C:\Program Files (x86)\Apache Software Foundation\Apache2.2\logs\error.log gives following error: The Apache2.2 service is running.

I tried using oldcert.pem and oldkey.pem on the same server and it works fine. Is there anything that I missed?

• Failover strategy for a 4 servers scenario

  - by Joao Villa-Lobos

  Hi all, I am trying to figure out how to set up replication & failover in a scenario with 4 servers (2 per location) where any server may assume the Master role. My initial scenario is the following one: 2 servers in location A (One Master, One Slave); 2 servers in location B (Two Slaves). For this I'm thinking on using the configuration Master-Master Active-Passive suggested on O'Reilly's "High Performance MySQL" on all of them so each one can become a Master when needed. If the Master "dies" the other server from location A assumes the Master role whenever possible. It will always have a bigger priority then the servers on location B. A server on location B will only switch to Master if no server on location A is able to do so. Since MySQL can't handle this automatically I need some other way to implement this. I've read already about heartbeat and Maatkit. Is this the way to go? Has anyone used this in a similar scenario? Is there some other way to go in order to achieve this? Any pointers about failout will be appreciated. I want to keep this as simple as possible avoiding stuff such as DRDB. I'm not concerned about high availability just a way to switch roles automatically without too many hassle. I'm using SuSe Enterprise 10 and MySQL 5.1.30-community. Thanks in advance, João
