• Make Apache to listen in multiple IPs

  - by Enrique Becerra

  Hi I'm in a big LAN, which is behind a proxy/firewall I'm working with an apache/php/mysql application, which is hosted in a small server besides my workstation. This server is connected to the LAN also and is behind the proxy: The server has a local IP assigned: 10.64.x.x Also, this server has a public IP assigned (or redirected from within the proxy/firewall) which is: 200.41.x.x I can't access public IP from LAN, but I can ping to the public IP from outside the building How should I configure Apache to listen also for public IP and open the 80 port for people accessing from outside the building?. It is set now to Listen 10.64.x.x:80 Thanks a lot in advance,

• Problem Assigning Static IP to CentOS Server

  - by nategood

  We have a sandbox server running CentOS that we run inside our office. Our ISP has assigned us a block of 5 static IPs. We now want to assign it a static IP. DEVICE=eth0 BOOTPROTO=none # have also tried "static" here HWADDR=00:13:72:*:*:* ONBOOT=yes TYPE=Ethernet NETMASK=255.255.255.0 IPADDR=173.*.*.161 GATEWAY=10.1.10.1 /etc/resolv.cnf is also set with the appropriate name servers from our ISP. When I ifdown eth0 then ifup eth0 I get... SIOCADDRT: Network is unreachable When I switch to DCHP, the machine has an IP assigned and there are no connection problems. Any ideas?

• Identifying the version of ATI Catalyst drivers

  - by snark

  I have bought a new video card based on the ATI Radeon HD 5670 chipset. I couldn't make it work with the latest ATI Catalyst drivers found on their website, only the drivers found on the CD delivered with the card worked. How can I know the version of Catalyst that is installed on my PC (running Windows 7 64-bits)? The ATI Catalyst Control Center returns the following information: Driver Packaging Version 8.673-091110a-092263C Provider ATI Technologies Inc. 2D Driver Version 8.01.01.973 2D Driver File Path /REGISTRY/MACHINE/SYSTEM/ControlSet001/Control/CLASS/{4D36E968-E325-11CE-BFC1-08002BE10318}/0000 Direct3D Version 8.14.10.0708 OpenGL Version 6.14.10.9120 Catalyst™ Control Center Version 2009.1110.2225.40230 I do not recognize anything pointing to a "marketing version". The website says the current version of Catalyst is 10.2.

• OS X SMB Connection to Windows Server 2008 R2

  - by Tawm

  I support many Macs that connect to an SMB share on a Windows Server 2008 R2 box. Occasionally I find that the Mac will try to connect and fail. The connection process will skip asking for credentials and there are none stored in keychain's password section. The server logs will show that the user tried to authenticate with invalid credentials. There are also no lingering connections from the server's point of view. The work around that I've found is to use an invalid username or a username that isn't the user's in the connection string for SMB so smb://domain;user@server/share instead of 'smb://server/share' this will force it to use the username I specified which the client doesn't have anything stored for. So it will then pop up the login window where the user changes the username to the correct one and user her password to connect happily. Specific computer in question: 15" MBP running Snow Leopard (10.6.7 or 10.6.8)

• Public IP Routing over Private GRE tunnel

  - by Paul

  I have a GRE tunnel configured between two linux boxes. The tunnel works fine. I can ping from each host the other private ip. Head privateip: 10.0.0.1 publicip: 8.8.8.8 Tail privateip: 10.0.0.2 publicip: 7.7.7.7 The public IP on Tail has the network block 9.9.9.0/23 statically routed over the 7.7.7.7 interface. The idea is to make the 9.9.9.0/23 ips work on servers on the 8.8.8.8 network. I configure the tail host to route the /23 block. I mounted a 9.9 IP on the head server. I can ping the 9.9 ip from the tail to the head. I can't ping the 9.9 ip from the public internet. I think I need to add some other routes because of gateway issues, but I can't seem to wrap my mind around it (not a router guy, just beating my way through something that I have never done before and vaguely understand) --danks

• Can't manage iPod from linux anymore

  - by kemp

  I used to be able to see and manage my iPod with different softwares: Amarok, Rhythmbox, GTKPod. The device is a nano 1st generation 4gb. Currently it mounts regularly and can be accessed from the file system, but I get this in dmesg: [ 1547.617891] scsi 11:0:0:0: Direct-Access Apple iPod 1.62 PQ: 0 ANSI: 0 [ 1547.619103] sd 11:0:0:0: Attached scsi generic sg2 type 0 [ 1547.620478] sd 11:0:0:0: [sdb] Adjusting the sector count from its reported value: 7999488 [ 1547.620494] sd 11:0:0:0: [sdb] 7999487 512-byte hardware sectors: (4.09 GB/3.81 GiB) [ 1547.621718] sd 11:0:0:0: [sdb] Write Protect is off [ 1547.621726] sd 11:0:0:0: [sdb] Mode Sense: 68 00 00 08 [ 1547.621732] sd 11:0:0:0: [sdb] Assuming drive cache: write through [ 1547.623591] sd 11:0:0:0: [sdb] Adjusting the sector count from its reported value: 7999488 [ 1547.624993] sd 11:0:0:0: [sdb] Assuming drive cache: write through [ 1547.625003] sdb: sdb1 sdb2 [ 1547.629686] sd 11:0:0:0: [sdb] Attached SCSI removable disk [ 1548.084026] FAT: utf8 is not a recommended IO charset for FAT filesystems, filesystem will be case sensitive!

Haven't been using my iPod for a while so I can't say when exactly it stopped working. I'm sure Amarok was still at version 1.X but can't remember when it was. My current system is debian testing fully updated. NOTE: just noticed that if I mount the device manually instead of letting nautilus automount it, I can see it again on GTKPod but still not on Banshee AND it's vanished from Rhythmbox...

• OpenVPN, Great on Windows, VERY slow on Mac...

  - by Phsion

  Hello, I'm not really an IT Pro, but this seemed like the best place to ask this question... I have setup VPN networks in the past, for fun, and everything was great, but now I've set one up for my boss, and while my computers all work great, his Mac machines are almost too slow to work with. Its pretty much vanilla configs all around, anyone have any ideas? Its a TUN routing setup over UDP. Back Story: My boss travels a lot, and wants to be able to access all his files from the road, and is also pretty paranoid about security (even though knows almost nothing about computers). SO i figured a VPN would be the answer. I went with OpenVPN, but there are some other issues. The only ISP we can get in our area besides Dial-UP is a crappy Satellite provider, that doesn't offer public IPs unless your willing to pay, so while the computers and VPN setup are pretty vanilla, the routing and structure is strange to get around this limitation. Specs: Its OpenVPN2, and there are six machines using it (only three actually use it, the rest are my test machines), one Windows 7 laptop, two XP Desktops, one OS X 10.5 Desktop, one 10.6 Desktop, and one 10.6 Laptop. One XP Desktop sits at my house and acts as the server (6Mbs/2Mbs FIOS connection). One XP desktop sits at the office and hosts a webpage that will wake up the Main Mac Desktop from sleep, and also ping all the machines on the VPN and show their status. The main office mac (10.6) stays in sleep mode until it gets the Wake-On-Lan packet from the Office XP, and then it auto connects to the VPN and opens itself up. The reason for all this is the Satellite private IP crap means i cant directly access the office machines outside of the LAN, so everyone connects to my house first, then they talk to each other from there. The Wake On Lan weirdness is because my boss doesn't want to leave the main Mac on all the time, and making a quick and dirty webpage was the easiest way to send a Magic Packet from inside the LAN without confusing my boss. The VPN uses Client Config files to make static IPs for the client. The only thing i found in google was some changes to the VPN MTU settings (down to 1400) but no real help. Oh, and i forgot...all the windows machines just have OpenVPN start as a service. The Mac laptop uses tunnelblick (an OpenVPN GUI) and the Mac Desktops use OpenVPN in normal command line mode.

• In DNS can an IN NS point to a CNAME?

  - by Mark Wagner

  Is it allowed to have an NS record be a CNAME? E.g.: subdomain.example.com. IN NS ns1.example.com. ns1.example.com. CNAME foo.example.com. foo.example.com. IN A 10.1.1.1 This doesn't seem to work in bind though this (of course) does: subdomain.example.com. IN NS foo.example.com. foo.example.com. IN A 10.1.1.1 Any pointers to RFCs prohibiting this setup would be appreciated.

• Can Acrobat 11 be made to do OCR using multiple CPU cores?

  - by tarcman.

  OCR processing takes time. Using multiple CPU cores would speed up processing. Acrobat 10 was not a multithreaded application. How about Acrobat 11? Does 11 by default do OCR using multiple CPU cores (if available)? If not, are there any workarounds, e.g. scripting, to help make Acrobat 11 do OCR using multiple CPU cores? Either through Acrobat's built in scripting language or using external scripts that launch and direct multiple single thread instances of Acrobat to in parallell to parts of the processing job. Note: This question is not too localized (not limited to a specific moment in time) because (1) Adobe does not release new major Acrobat versions very often (Acrobat 10 was released two years ago) and (2) Adobe Acrobat is a widely used application.

• tar incremental backup is backing everything up, every time when used on the Dropbox directory

  - by Cyclic

  I made an incremental backup about 10 months ago (on Jan 27, 2013), creating a .snar metadata file. Now, when I try to make an incremental backup using tar --create --file=dropbox_incremental_1.tar --listed-incremental=dropbox_0.snar Dropbox the command just re-backs up everything. I'm not an expert at Unix timestamps, but I noticed that virtually all of my directory timestamps are way more recent than the last time they changed. For my actual files, they look like this: Access: 2013-03-12 19:04:51.000000000 -0500 Modify: 2012-09-30 15:10:47.000000000 -0500 Change: 2013-03-12 19:04:51.306209672 -0500 The 'Modify' timestamp seems correct, but the files were definitely not changed (at least not doing anything that I know of) at the time they say they were. These files still seem to go into the incremental archive. What's happening here? Is there a way to tell tar to look at the 'modify' timestamp? Isn't this what it's supposed to be doing?

• Redhat with a reverse proxy, a specific configuration

  - by jessica

  The setup I am trying to put together consists on a server connected to the internet (a redhat box) and 2 Apache Tomcat boxes not connected to the internet. Let's call the server Server and the two Apache Tomcats, Apache1 and Apache2. So, assuming my external IP is 102.1.1.1, Apache1 is 10.1.1.1 and Apache2 is 10.1.1.2, what I'm trying to configure is a reverse proxy so that if the request goes into http://102.1.1.1/mywebserver1/ it will be directed to Apache1 and if the request goes into http://102.1.1.1/mywebserver2/ it will be forwarded to Apache2. Now, I don't need a cache on the proxy since there is application sitting in those tomcats and each request needs to get a fresh answer. I searched for a while and I tried building this with Squid but i can't get it to work the way I need it. Anyone knows how to do this? What software do I need? How do I configure the reverse proxy? Thanks! jessica

• Server load spikes several times a day, load average for the past month is 5 times the load average all year

  - by AMF

  My Munin notifications set up for our (Debian) LAMP cluster have been notifying me continuously that our load on our production machine has been at dangerous levels. While the average load all year typically runs between 2 and 8, the load in the past month and only the past month -- has been skyrocketing to 10, 18, and occasionally even 50-60. The spikes last only 5-10 minutes at a time and occur about every 2-3 hours. The spikes do not effect performance only because I have a script that sends traffic off our server to a mirror CDN when the load goes above 10. I've looked for cron jobs that correlate with this timeframe but there is nothing I can see that would cause this. Site traffic is also normal (we receive about 200K visits per day). I'm also trying to think of anything I've changed around the time this problem began, and I really cannot think of anything. This is probably not much to go on. Maybe there is a clue in the top print-out (below) that I'm not seeing.

• Bash Script Exits su or ssh Session Rather than Script

  - by Russ

  I am using CentOS 5.4. I created a bash script that does some checking before running any commands. If the check fails, it will simply exit 0. The problem I am having is that on our server, the script will exit the su or ssh session when the exit 0 is called. #!/bin/bash # check if directory has contents and exit if none if [ -z "`ls /ebs_raid/import/*.txt 2>/dev/null`" ]; then echo "ok" exit 0 fi here is the output: [root@ip-10-251-86-31 ebs_raid]# . test.sh ok [russ@ip-10-251-86-31 ebs_raid]$ as you can see, I was removed from my sudo session, if I wasn't in the sudo session, it would have logged me out of my ssh session. I am not sure what I am doing wrong here or where to start.

• Apache/Jboss Issue - is this connection timeout?

  - by user115391

  We have an application. The architecture is as below 1 load balancer (apache), which redirects to 2 app servers (jboss). The site is working fine and I am able to access it fine. But sometimes, randomly the homepage takes a while (like 30-40 secs) to load. I tried checking the logs but could not figure out why. I used the httptraffic analyzer, fiddler to see the traffic, but it just says the request/response took 30 secs or so. I checked the apache access logs, mod_jk.log.

• Solaris10 x86 mirror. Making second disk booteable when failure

  - by Kani

  Did a mirror (RAID1) with Solaris 10 in x86. Everything OK. Now, I´m trying to make the second disk booteable, this is: from grub or in case of failure of disk1. I edited /boot/grub/menu.lst: #---------- ADDED BY BOOTADM - DO NOT EDIT ---------- title Solaris 10 9/10 s10x_u9wos_14a X86 findroot (rootfs1,0,a) kernel /platform/i86pc/multiboot module /platform/i86pc/boot_archive #---------------------END BOOTADM-------------------- #---------- ADDED BY BOOTADM - DO NOT EDIT ---------- title Solaris failsafe findroot (rootfs1,0,a) kernel /boot/multiboot -s module /boot/amd64/x86.miniroot-safe #---------------------END BOOTADM-------------------- #---------- ADDED BY BOOTADM - DO NOT EDIT ---------- title Solaris failsafe findroot (rootfs1,0,a) kernel /boot/multiboot kernel/unix -s module /boot/x86.miniroot-safe #---------------------END BOOTADM-------------------- #Make second disk booteable!!!!!!! title alternate boot findroot (rootfs1,1,a) kernel /boot/multiboot kernel/unix -s module /boot/x86.miniroot-safe But is not working.

• Using VLANs that are routed together?

  - by dannymcc

  I have a quick question that's bugging me the more I read about VLANs. So far I understand that they are useful for dividing the network into sub-sections, but if you route them together does that not remove any security benefit? As an example, if I created a VLAN on my home network which was simply one computer, one server and one router.if I wanted to divide the network between computers and servers I could put the computer on VLAN 10 and the server on VLAN 20. Then the computer would no longer be able to communicate with the server - unless I added a static route to the router that connected the two together, basically telling VLAN 10 that VLAN 20 exists and how to communicate with it. The VLANs would then be connected in a similar way to a 'flat' network that has no VLANs. Therefore, surely, all security benefits are lost. Am I missing something?

• Ping isn't acting accurate?

  - by Earlz

  I've been trying to diagnose some latency issues with my internet connection. I've been lagging out of online video games and such, which of course could be their server's fault. So, I've been running ping some. It doesn't indicate anything unusual, but it does act a bit strange. I can start it with something like ping internethost -i 0.1 so that it will send a ton of packets, and every 10-20 seconds it will appear to just freeze for 2 or 3 seconds. The packets are still being received in the right order though, and there is no packet loss. The weirdest thing is that after the little freeze up, it will usually just report a ping time that is about 10-30ms higher than the average. How does this happen? Is ping still being accurate? I'm using Arch Linux. The host I'm pinging is my website, which shouldn't be doing any kind of ping slowing or filtering.

• PHP Mail() to Gmail = Spam

  - by grantw

  Recently Gmail has started marking emails sent directly from my server (using php mail()) as spam and I'm having problems trying to find the issue. If I send an exact copy of the same email from my email client it goes to the Gmail inbox. The emails are plain text, around 7 lines long and contain a URL link in plain text. As the emails sent from my client are getting through fine I'm thinking that the content isn't the issue. It would be greatly appreciated if someone could take a look at the the following headers and give me some advice why the email from the server is being marked as spam.

• How to restore missing space in NTFS file systems

  - by jacobsee

  I have a 40 GB USB hard drive formatted with NTFS on a PC running Windows XP Pro, SP3. I am trying to free as much space as possible. Windows Explorer tells me that I have about 200 MB of files on the drive (showing hidden and system files). When I show drive properties however it shows 73% free, around 10 GB used. I ran CHKDSK and it found all kinds of problems. Now running defrag and it is behaving as if there were 10 GB of files, but I can't access them anywhere. How to find and remove this extra 10GB?

• Why are emails sent from my applications being marked as spam?

  - by Brian

  Hi. I have 2 web apps running on the same server. The first is www.nimikri.com and the other is www.hourjar.com. Both apps share the same IP address (75.127.100.175). My server is through a shared hosting company. I've been testing my apps, and at first all my emails were being delivered to me just fine. Then a few days ago every email from both apps got dumped into my spam box (in gmail and google apps). So far the apps have just been sending emails to me and nobody else, so I know people aren't manually flagging them as spam. I did a reverse DNS lookup for my IP and the results I got were these: 100.127.75.in-addr.arpa NS DNS2.GNAX.NET. 100.127.75.in-addr.arpa NS DNS1.GNAX.NET. Should the reverse DNS lookup point to nimikri.com and hourjar.com, or are they set up fine the way they are? I noticed in the email header these 2 lines: Received: from nimikri.nimikri.com From: Hour Jar <[email protected]> Would the different domain names be causing gmail to think this is spam? Here is the header from one of the emails. Please let me know if any of this looks like a red flag for spam. Thanks.

• Using OpenVPN, yet netflix.com blocks access

  - by user837848

  I have set up an OpenVPN server on a VPS in the USA and configured it to route all clients traffic through it. Everything seems to work fine regarding the VPN connection in gerneral. All ip lookup sites show me the us server's ip address and even hulu.com works(it won't work if you are not in the usa). But for some reason netflix.com says "Sorry, Netflix is not available in your country yet.". So I thought that netflix probably uses some more sophisticated ways to determine your location beyond just your ip address. But I could not find a way to get it to work until I dropped the idea of using a VPN and instead connected to the server via a simple socks tunnel with ssh by running: ssh -D 9999 user@serverip All I had to do was changing the key network.proxy.socks_remote_dns in Firefox from false to true to prevent DNS leaks and setting up the socks proxy. Then I could finally watch netflix.com. As a result I concluded that there is nothing in the browser(or something like system timezone) that tells netflix the location, so it has to have something to do with the OpenVPN config. After that I used tcpdump to log all the traffic on the server's network interface venet0 (OpenVZ VPS), visited netflix.com on the client while first connected to the VPN and then connected via socks tunnel and afterwards compared both outputs. The only thing that caught my eye was that while using the socks tunnel the server mainly used ipv6 to connect to netflix whereas it only used ipv4 when the client was connected to the OpenVPN server. But I don't get how that could make such a difference. So what am I missing? Is there a way to configure OpenVPN to also use ipv6 to connect to a website although there is only an ipv4 connection between the VPS and the client? Here is the server.conf of the OpenVPN server (OpenVZ VPS) local serverip port 443 proto tcp dev tun ca ./easy-rsa2/keys/ca.crt cert ./easy-rsa2/keys/vps1.crt key ./easy-rsa2/keys/vps1.key # This file should be kept secret dh ./easy-rsa2/keys/dh1024.pem server 10.8.0.0 255.255.255.0 ifconfig-pool-persist ipp.txt push "redirect-gateway def1 bypass-dhcp" push "dhcp-option DNS 8.8.8.8" push "dhcp-option DNS 8.8.4.4" client-to-client keepalive 10 120 tls-auth ta.key 0 # This file is secret cipher AES-256-CBC comp-lzo max-clients 4 user nobody group nogroup persist-key persist-tun status openvpn-status.log log-append openvpn.log verb 3 iptables forwarding iptables -t nat -A POSTROUTING -s 10.8.0.0/24 -o venet0 -j SNAT --to-source serverip (enabled ipv4 forwarding) I have tried everything always on a Win7 and a Debian client with only ipv4 connections and always made sure that they use the correct DNS server (tested with ipleak.net and tcpdump / wireshark). client.conf: client dev tun proto tcp remote serverip 443 resolv-retry infinite nobind persist-key persist-tun ca ca.crt cert client.crt key client.key ns-cert-type server tls-auth ta.key 1 cipher AES-256-CBC comb-lzo verb 3

• Logging Timeout'd Request in Apache 2.X

  - by m3rLinEz

  Hello, I am migrating some applications from Apache 1.3 to 2.2. We used to run some tests where attacker opens some HTTP connection to our server, and do nothing. Apache 1.3 would log the following 408 code, for example: 126.1.86.85 - - [01/Dec/2010:06:26:19 +0000] "-" 408 - "-" 0 126.1.86.85 - - [01/Dec/2010:06:26:19 +0000] "-" 408 - "-" 0 But with Apache 2.2, nothing is logged to the log file. I run the same test by using netcat to open the connection: $ nc IP_victim PORT_victim $ nc 10.42.37.3 80 I would like to have Apache 2.2 log the same 408 code to the log file, so that we would know of attempted DoS attack from the outside. Do I need any more configuration in Apache 2 to enable this? I have tried some different configurations such as LogLevel = Debug, Timeout 30, RequestReadTimeout header=10 body=30. Thanks.

• Wireless router blocking some sites while using ethernet is fine

  - by Micke

  I'm using Windows 7 and my router is a wireless Apple Airport Express that is approximately two years old. Suddenly I can't access some sites (for example www.sthlm.friskissvettis.se, or www.vegetarian-shoes.co.uk, some streamed tv-shows on svtplay.se, and a number of other random sites) when connecting to internet with my router. It worked good until recently and I'm fairly sure this problem emerged when my ISP upgraded from 10/10mbit to 100/10mbit speed. Most other sites like facebook and google works fine. When using my network cable to connect to internet everything works fine and I can access these sites. Firmware is current and I've tried reseting the router to factory defaults. Tried different browsers, and I can't ping the "blocked" sites either. Tracert www.sthlm.friskissvettis.se starts with 10.0.0.1 and continues through a number of long addresses until it says timeout. The last working address before timeout was sth-tcy-ipcore01-ge-0-2-0.neq.dgcsystems.net [83.241.252.13], if it matters. Tracert www.vegetarian-shoes.co.uk also eventually gives me a timeout. When the network cable is plugged in, I still get timeout on tracert www.sthlm.friskissvettis.se even though I can access the site in Chrome. Weird. www.vegetarian-shoes.co.uk doesn't give me a tracert timeout when the cable is plugged in, and I can access the site as usual. I've tried changing DNS servers to use opendns servers instead, but to no use. I've tried pinging these two sites with a lower MTU packet size (with this method: http://www.richard-slater.co.uk/archives/2009/10/23/change-your-mtu-under-vista-or-windows-7/), but still can't access them through ping... I don't know what to do anymore.... any suggestions???
