• Ntop monitoring - Hosts visible with no SPAN/mirroring

  - by Cory J

  I am attempting to use ntop to monitor traffic over a Cisco Catalyst switch. I was assuming that in order to see any of the traffic, I'd have to use monitor, as described here: http://www.cisco.com/en/US/products/hw/switches/ps708/products_tech_note09186a008015c612.shtml. Howver, before I did anything on the switch, I simply plugged my ntop server in and fired up ntop. To my suprise, I instantly see 3+ pages of hosts, and thousands of packets. How is ntop seeing this? I have verified that no monitoring exists on the switch (run as en): cs1.pvdc#show monitor No SPAN configuration is present in the system. My ntop server is Ubuntu 8.04, I haven't done ANY configuration, I just installed the ntop package. This is also a fresh Ubuntu install. Is there anything else on my switch besides "monitor" that might cause my switch to mirror all its traffic like this? I've tried plugging ntop into different ports with the same results. UPDATE: It appears to be more then just broadcast traffic showing up in ntop, for example, I can see when my IPs have talked to the DNS server or generated HTTP traffic. If my switch is misconfigured, can anyone point me in the right direction towards rectify this? Not a Cisco expert.

• Please, help writing a MIB

  - by facha

  I have a problem with an snmpwalk query returning snmp variables in a non-uniform way: .1.3.6.1.2.1.10.127.1.3.3.1.2.215 -> Hex-STRING: 24 37 4C 0C 65 0E .1.3.6.1.2.1.10.127.1.3.3.1.2.216 -> Hex-STRING: 24 37 4C 0B A2 DA .1.3.6.1.2.1.10.127.1.3.3.1.2.217 -> STRING: "$7L f:" .1.3.6.1.2.1.10.127.1.3.3.1.2.218 -> STRING: "$7L k2" As you can see, some variables are of a STRING type, others are Hex-STRING. So, I'm trying to write a simple MIB to force them all come out as Hex-STRING. This is where I've gotten so far: TEST-MIB DEFINITIONS ::= BEGIN PhysAddress ::= TEXTUAL-CONVENTION DISPLAY-HINT "1x:" STATUS current SYNTAX OCTET STRING test OBJECT-TYPE SYNTAX PhysAddresss MAX-ACCESS read-only STATUS current ::= { 1 3 6 1 2 1 10 127 1 3 3 1 2 } END However, snmpwalk doesn't seem to notice my textual convention (even though the "test" variable is being recognized). I still get a mixture of STIRNGs and Hex-STRINGs. Could anybody point to where is my mistake? snmpwalk -v2c -cpublic 192.168.1.2 TEST-MIB::test ... TEST-MIB::test.216 = Hex-STRING: 24 37 4C 0B A2 DA TEST-MIB::test.217 = STRING: "$7L f:"

• Acer Aspire One getting extremely hot

  - by ascom

  I have an Acer Aspire One D250-1197. I really better type fast before it overheats again... For some reason, I'm having a problem with heat on my netbook only when I run Joli OS (Ubuntu 9.10 LTS?). When I leave it idle, with nothing running (other than the regular Joli OS desktop and a couple of doing-nothing terminals), heat slowly builds up to the point where the netbook is burning hot to the touch. I have never had this problem when running Windows 7 Starter (even though it gives me plenty of other headaches). It seems that the fan is spinning, but not fast enough to keep up with the heat buildup. Is there something wrong with the fan drivers? The computer doesn't seem to recognize that it is overheating. What can I do to solve this problem (other than shut it off or use Windows)? I'm currently on the wrong side of Earth (I mean, on vacation), so I just need a temporary fix, such as a driver I can install. Also, I have to use Linux, because I have to share out the wired connection in hotels wirelessly to the iPhones. EDIT: I'm switching from Joli OS to a more "proper" and up to date distribution (Xubuntu 13.04). I'll see if it still has the heat problem and try @nod's cpufreq idea.

• Windows Vista will not boot; the file header checksum does not match the computed checksum

  - by Magnus

  Right out of the blue, my wife's Sony Vaio stopped booting. This, not so fun, error message displays immediately after POST: The system cannot boot. The file is possibly corrupt. The file header checksum does not match the computed checksum The repair option on the Vista DVD says everything is fine and dandy, it couldn't be more happier or more clueless... Any ideas? Update: CHKDSK reports no issues. CHKDSK /r reports no issues. (Heck, both Windows Repair and CHKDSK could just as well tell me that I have won on lottery or that the earth is flat... ) Some have reported that a mem diagnostic could help, but for me the mem diag has just ran through 5 passes. It doesn't seem to help. According to Sony, pressing F10 should bring up the restore menu, but it doesn't, the error pops up straight after Bios POST. It seems that this error is first in line of all options at this point, and is doesn't put a smile on my face. I have attached an external USB drive and copied all user data/documents to it. I feel an OS re-install is around the corner.

• Amazon AWS Ec2 instance, Elastic IP, Domain name from external domainseller, and Google Apps for Email

  - by Sid

  We are hosting our site on an Ec2 instance. Our Elastic IP is w.x.y.z and Public DNS is: ec2-w-x-y-z.compute-1.amazonaws.com. We've bought a domain name domainname.com from a lesser known domain-name-seller. We added an A-record pointing domainname.com to w.x.y.z. Will this work or do we need a CNAME record to point to the same too? We wanted to use Google apps for emailing so adjusted the TXT/MX records according to the Google Apps instructions to be able to send/recv email using @domainname.com email addresses. Have we got it right, more important, we came across queries relating to email sent from ec2-w-x-y-z.compute-1.amazonaws.com (our users can send email from their onsite accounts) going to spam (rDNS not pointing to domainname.com but to ec2-w-x-y-z.compute-1.amazonaws.com). How can we fix this? We came across SPF records, do they provide a complete solution? We aren't sure as to how to use them. Can you help pls? Thank you, Sid

• Opening and Testing Ports on Modem > Router Connection

  - by JakeTheSnake

  Working off of my last question, I can access my server's FTP over the LAN but not over the internet. I'm using Filezilla on port 666. My router/modem configuration is as such (similar to other post): 1) Modem connects to WAN 2) WAN port on modem connects to LAN port on Router 3) Modem internal IP address is 192.168.0.254 4) Router internal IP address is 192.168.0.1 5) Modem has DHCP turned OFF 6) Router has DHCP turned ON 7) Router is running Tomato firmware and it's set as 'Router' (not 'Gateway') 8) The internet is working (just had to say that) I've set up port forwarding both on the modem and router - both route port 666 to the IP address of 192.168.0.3 (TCP); that is the IP address of the server which has FileZilla running. I don't know if that's hindering anything but I've also tried it with just the modem and just the router...same result. I've also tried setting the server to be DMZ (both on router and modem). Neither router nor modem have anything in their logs about denying inbound traffic on port 666 so my ability to troubleshoot stops there. I've tried contacting my ISP (Telus, running on mobility plan...it's a "Smart" Hub) but they weren't much help. They said they only block port 25 and 80 and maybe a few others, but not most ports. I test whether or not the port is open by going to canyouseeme.org - I don't know whether or not that would produce a 'connection refused' result just based on the fact that the FTP requires a login...I'm not well versed on this matter. FWIW, sometimes I get a 'connection refused' error on canyouseeme.org but mostly it's 'connection timed out'. I don't know what else to do at this point.

• Can IIS (Ideally Azure) do SSL Proxying?

  - by Acoustic

  My team has been asked to add a new feature to a project we're working on, and none of can find authoritative details on whether it's possible with Windows/IIS. The short of it is that we're hoping to have customers update their DNS with a CNAME record to point their website to our server instead of theirs (they why's are trivial - it's what the app does on behalf of your site). We're using a reverse proxy with several custom modules to serve particular content from the original servers. So far everything works perfectly until we encounter SSL. Is there a way to have IIS serve up an SSL certificate from another server? In other words, is there a way to be a trusted man in the middle? I'm hoping that's possible so that we don't have to require all our clients to re-issue their SSL certs. Frankly, we don't want to have to manage hundreds of certs. I'd also like to avoid a UCC situation if there's a way to because it seems to require re-creating the cert each time a client is added. So, any pointers on proxying/hosting SSL (or even dynamic SSL hosting like http://www.globalsign.com/cloud/) would be appreciated.

• Way to speed up load-balanced ssl using nginx?

  - by paulnsorensen

  So the setup for our website is 4 nodes running rails 3 and nginx 1 that all use the same GoDaddy certificate. Because we are a paid site, we have to maintain PCI-DSS compliance and thus have to use the more expensive SSL ciphers -- also we force SSL using Rack. I've recently switched over to Linode's NodeBalancer (which I've read is an HACluster), and we're not getting the performance we'd ideally like. From what I've read, it looks like terminating the SSL on the nodes using the high cipher is what is causing the poor performance, but I'd like to be thorough. Is there anything I can do? I've read about other ways to terminate the SSL before the NodeBalancer (like using stud), but I don't know enough about these solutions. We certainly don't want to do anything experimental or anything that has a single point of failure. If there really isn't anything I can do to speed up the SSL handshake, my alternative would be to support certain pages on Rails using a secure and insecure subdomain. I've found a few guides that walk through that, but my resulting question is in this situation, would it be better to have nginx handle forcing ssl on the secure subdomain instead of rails? Thanks!

• Migrating Windows XP BOOT.INI Settings to Windows 7 Boot-loader

  - by Synetech inc.

  Hi, Two months ago my motherboard died, so I bought a used computer that came with Windows 7. I have since installed my old hard-drive, which had Windows XP on it, in this system. What I am trying to do now is to figure out a way to migrate the settings from XP's BOOT.INI into 7's boot-loader. Below is the BOOT.INI I used in XP (I have reduced the strings and updated the disks to point to the new location of the old HD. Oh and I am not clear on the drive letters. In XP, I could boot the recovery console or MS-DOS from a file in C:\ that contains the boot-sector. I am not sure what drive letter it would be called now—I had to manually change all the drive letters of the old partitions in Windows 7 because it auto-assigned them all wrong/differently). [boot loader] timeout=10 default=multi(0)disk(0)rdisk(1)partition(1)\WINDOWS [operating systems] multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="XP" /fastdetect multi(0)disk(0)rdisk(1)partition(1)\WINDOWS="XP (Safe)" /safeboot:network /sos /bootlog /noguiboot C:\CMDCONS\BOOTSECT.DAT="Recovery Console" /cmdcons C:\BOOTSECT.DOS="MS-DOS 7.10" /win95 I have looked around, and have only been able to find some bcdedit commands to add XP to the boot-loader, but none that include information on setting safe-mode for it (or changing any of the XP load options for that matter). Not surprisingly I suppose, I have not found anything on adding the XP recovery console or DOS to the Windows 7 boot-loader. (Yes, I tried EasyBCD, but that did not help; it had no options for XP, and the best I managed was to get a choice of booting 7 or normal-mode XP—choosing XP didn't even give the old XP boot menu.) Can anyone please tell me how to export the entries in XP's boot.ini to 7's boot-loader so that on boot, I can choose to load the following: Windows 7 Windows 7 (Safe-mode) (Windows 7 (The Win7 counterpart of the Recovery Console)) Windows XP Windows XP (Safe-mode) Windows XP (Recovery Console) MS-DOS 7.10

• Wordpress hacked. Disabled hacked site but bad traffic continues [closed]

  - by tetranz

  Possible Duplicate: My server's been hacked EMERGENCY My Ubuntu 10.04 LTS VPS has been hacked, probably via a WordPress site. I was alerted to it when I noticed the incoming traffic was unusually high. A WordPress site was littered with eval(base64_decode(...)) code in lots of files. My fault, I had some files writeable by www-data which shouldn't have been. I've disabled that site (a2dissite ... and restart Apache). This has reduced it but I am still getting some malware type traffic. My server runs several WordPress and Drupal sites and a home grown PHP site. I have captured traffic with tcpdump and looked at it Wireshark. It's reaching out to the login page of some Joomla sites, trying multiple logins. The traffic stops when I stop Apache. If I a2dissite every site and reload (not restart) Apache the traffic continues. At that point I have no virtual hosts running and no DocumentRoot in my apache2.conf so I don't know how Apache is still running something. I have searched the other sites with grep for likely looking php code with no success. I may have missed it but I haven't found anything suspicious in the Apache logs. I have mod-status running. I haven't really seen anything much there except that someone is still trying to do a POST to the theme page on the disabled WordPress site but they now get a 404. What should I be looking for? Are there any tools or whatever which would give me more info about how Apache is generating that traffic? Thanks

• Is one server on a vlan unnecessary?

  - by moomoochoo

  DETAILS I've been researching web hosting solutions in Japan. Based on this question one of the services available seems to be a VLAN. I've read about the advantages of such a system for a large organization, but there doesn't seem to be much information regarding smaller setups. I take that to mean that for one server it is likely to be unnecessary? My concern is that I don't know how many other servers are on the WAN, so regardless of how many servers I use a VLAN might still be a good idea. SERVER INFO One dedicated server would be used. It would not be virtualized. My Research so far Based on comments here, a VLAN would be useful for mitigating these problems. A user on another server could, either mistakenly or maliciously, assign one of your IP addresses to their server, resulting in a "duplicate IP" situation that would cause connectivity issues. A user on another server could poison the arp cache and potentially redirect traffic to snoop on communication intended to/from your server. (later in the discussion this point was said to be unrealistic.) QUESTION Is it worthwhile getting a vlan for one dedicated server? Will it be easier/the same/ harder to manage?

• Weird .#filename files on remote ssh-connected systems after mcedit

  - by etranger

  I'm using MacFusion sshfs in combination with Midnight Commander, and when I edit remote text files with mcedit, weird symlinks are created on the remote system. $ ls -l .* lrwxr-xr-x 1 user group 34 Jun 27 01:54 .#filename.txt -> [email protected] where etranger is my local login name, and mbp is a hostname of my notebook running MacOS. symlinks can be removed by running remote rm command, but cannot be deleted on the mac-fuse mounted volume and thus pollutes the filesystem. I cannot figure what part of software is responsible for this, and how I could fix this, any help is appreciated. EDIT: This appears to be mcedit behavior as documented here: https://dev.openwrt.org/ticket/8245 Apparently, sshfs fails to remove symlink to the lock file for some reason (".#" in filename, perhaps), and it pollutes the filesystem. A quick workaround is possible, using another bug of Midnight Commander: editing (F4) the broken symlink effectively converts it to a missing lock file it was supposed to point to, and removes the symlink itself. The newly created file may then be deleted normally. EDIT 2: Unchecking "Follow symlink" in MacFusion apparently allows sshfs to remove dead symlinks, so the problem disappears completely.

• PHP 5.3 on IIS gives 404 error in CGI mode

  - by reinier

  Slowly losing my mind here. I had PHP 5.2 working fine (ISAPI) under IIS, but for some extension I needed 5.3. So no worries, I installed this but it turns out ISAPI is not supplied anymore. I followed the install tutorials for fastcgi and ended up with a 500 internal server error for every PHP page served. So my current situation is: I have fastcgi removed. In my websites I have added PHP (head, get, post) and routed them to c:\php\php-cgi.exe. Result: every PHP page I try (even the ones with just text) gives 404 not found error. Any HTML file I put in the same folder, serves without a hitch. Who can help me please... How hard can something like this be right? For me apparently very hard. Extra information: ran the installer as suggested below. Set it to use fastcgi. my fcgiext.ini file looks like this now: [types] php=c:\php\php-cgi.exe [c:\php\php-cgi.exe] exepath=c:\php\php-cgi.exe from the command-line a 3 line PHP file with just phpinfo(); works fine from the server the same PHP file with just phpinfo(); results in the internal server 500 error. from the server a PHP file with just text works fine when changing the document types in IIS management console and point the PHP extension directly to c:\php\php-cgi.exe results in 404 for every PHP file the php.ini is the php.ini.production file which came in the distribution. No edits were made. Setting the IIS PHP handler directly to PHP (not via fastcgi) c:\php\php-cgi.exe results in the following: display a PHP page with only text....works fine display a page with only phpinfo(); results in 404 not found

• Need to link WP Blog with Rails App on Heroku

  - by John Glass

  I have a client who wants to migrate his Rails app to Heroku. However the client also has a blog associated with his domain that runs on WordPress. Currently, the WordPress blog is running happily alongside the Rails app, but once we migrate to Heroku, that clearly won't be possible. The url for the app is like http://mydomain.com, and the url for the blog is like http://mydomain/blog. I realize that the best long-term solution is to redo the blog in a Rails format like Toto or Jekyll. But in the short term, what is the best way to continue hosting the WP blog where it is (or somewhere) but use Heroku to run the app? The client doesn't want the blog to be on a subdomain, but to remain at mydomain/blog for SEO reasons and also since there is traffic to the blog. I have two ideas: Use rack_rewrite or refraction (or just a regular old 301 and Apache mod_rewrite) on the old (non-Heroku) server to redirect the main url from the old site to Heroku. In this case, I can just leave the Wordpress blog running happily where it is. I think?? Is there a reason to choose one of those options (rack_rewrite, refraction, or mod_rewrite) over the others if I do it this way? Switch the DNS info to point to the Heroku site, and then use a 301 redirect from the blog to the old site. But then I'll have to get the old (non-Heroku) site on a subdomain and use some kind of rewrite rules anyway so it looks like it isn't a subdomain. Are either of these approaches preferable, or is there another way to do it that's easier that I'm missing?

• Kernel panic while loading Mac OS X on VMWare

  - by Vladimir Gritsenko

  I'm trying to run Mac OS X 10.6.3 on VMWare 7.1 from within Windows 7 64 bit. Trying to run the OS X doesn't work - shortly after booting VMWare announces the machine's death with this pop-up message: The CPU has been disabled by the guest operating system. You will need to power off or reset the virtual machine at this point. The console has a more interesting announcement: The real-time clock was not properly initialized on your system! With a dump of the detected CPU speed (~2.9 GHz), FSB (~94 MHz) and bus ratio (31). Somehow, the code that panics is documented in an accidental .diff file here. Apparently, it commits seppuku if the bus ratio is greater than 30. I underclocked my E6500 to a slower speed, but this apparently didn't make any difference. I can think of two possibilities right now: The CPU info being read is constant, and defines the maximum ability of the CPU. In which case it appears I'm screwed. VMWare presents its own CPU info to the machine, which I can perhaps somehow change. If so, how? If these sound completely off, that's because I'm a real newbie in these matters. Here's hoping you guys can show me the light :-)

• Change the default program for a filetype to something not in "Program Files" in Windows Vista

  - by Carson Myers

  I'm trying to make my python scripts run in python 2.6 by default when run from the command line. This is paired with adding certain scripts to the PATH variable and .py to PATHEXT for convenience. But I'll be damned if I can get the file type association to work. In the default programs dialog (found in control panel) I find .py, and click "Change Program." This gives me the same dialog as clicking "Open with..." on a file's context menu. I search for python. Tell it to use python, but it doesn't add it to the list of programs I am allowed to use. I tried making a shortcut to python in Program Files, but that won't work either. If I copy python into a folder in Program Files, then that works. But why can't I just point it at C:\python26\python.exe (which is in the PATH variable) in the first place? Is there a way around this, or do I have to just reinstall python into Program Files?

• Openfire on EC2 with Jingle

  - by Bjorn Roche

  I would like to run Openfire (or another XMPP server) on EC2. At the moment this is just for testing, so easy setup and configuration are important, as is low cost. At some point, however, if things go well, it will be important to scale this. Ideally, it would be nice to not have to switch software when the scaling happens, but if a switch needs to happen later it certainly can. My requirements are: basic XMPP services, including muc and pubsub. Logins controlled from an external API. Preferably, when a user attempts to connect, the XMPP server checks with the api to see if their username and password are correct, but I can also have the API keep the XMPP server up to date on new users, deleted users, pasword changes and so on. I see Openfire has a "user service" API. Not ideal, but it looks workable. Jingle, including relay and STUN. It's not at all clear to me if the Jingle Nodes plugin takes care of this. I'm a bit confused about what's required to set this up, and I'd rather know in advance than be confused along the way :). eg It seems like STUN servers require more than one IP address. Can Openfire do all this for me, including stun and media relay on a single machine? Is this hard to configure on EC2 with Openfire? What are the basic steps? Would this be easier with something else like, say Tigase? What about database? Should I use amazon's database service, or run a db on the same machine? Would the server be compatible with a service like http://www.siteuptime.com/ Thanks!

• win8: access denied to external USB disk; update access rights fails

  - by Gerard

  I use to work with 2 laptops (vista and win7), my work being files on an external usb disk. My oldest laptop broke down, so I bought a new one. I had no option other than take win8. 1/ I suspect something changed with access rights, as my external disk suffered some "access denied" problem on win8. I was prompted (by win8) somehow to fix the access rights, which I tried to do, getting to the properties - security. This process was very slow and ended up saying "disk is not ready". Additonnally, the usb somehow was not recognized anymore. 2/ Back to win7, I was warned that my disk needed to be verified, which I did. In this process, some files were lost (most of them i could recover from the folder found00x, but I have some backup anyway). Also, I don't know why, but under win7, all the folder showed with a lock. 3/ Then back again to win8. Same problem : access denied to my disk + no way to change access rights as it gets stuck "disk is not ready". Now I am pretty sure there is some kind of bug or inconsistence in win8 / win7. I did 2/ and 3/ a few times. At some point, I also got an access denied in win7. I could restore access rigths to the disk to "system" (properties - security - EDIT for full control to group "system" ...). But then I still get the same access right pb on win8, and getting stuck in the process to restore full control to "system" -- and "admin" groups. Now, after I tried for more than 3 days, I am losing my patience with that bloody win8 which I did not want to buy but had no choice. I upgraded win8 with the windows updates available. Does not help. Anybody can help me ?

• I used disk copy to clone my drive, now my windows 7 profile won't load correctly

  - by RzK

  I used easeuse disk copy, after acronis, clonezilla, windows image restore failed me. Basically it copys all sectors, I set it to skip bad sectors(40). The source drive works, it just gave me a couple errors and stopped booting at one point. The drive is an identical copy, minus 40 bad errors. The drive is set to C and active partition, I rebuilt the boot order. I've ran sfc /scannow and ran chkdsk /r chkdsk found 20kb of bad sectors if I remember right. Now the issue I get is when I log into my profile which was saved right, I get a blank light blue wallpaper (non-license) explorer.exe is not running, and there are only 4 processes running in taskmanager, including taskmanager. I would try a repair install but CRTL-E would not open, nothing will open once I force start explorer.exe, almost like all services are down. What should I do? Fresh install is almost not a possibility I will try and fix this issue. sfc /scannow /offbootdir=c:\ /offwindir=c:\windows returns "Windows Resource Protection could not perform the requested operation"

• I keep losing wireless connection

  - by posfan12

  I have a WRT54GL v1.1 wireless router and a WUSB54G v4 wireless adapter, both made by Linksys. The router is in the living room by the TV and the my computer is in the bedroom. My ISP is Brighthouse. Operating System Microsoft Windows 7 Home Premium 64-bit SP1 CPU Intel Core 2 Duo E6600 @ 2.40GHz 36 °C Conroe 65nm Technology RAM 3.00GB Single-Channel DDR2 @ 333MHz (5-4-4-14) Motherboard eMachines EMCP73VT-PM (CPU 1) 26 °C Graphics ASUS VS247 (1920x1080@60Hz) 767MB GeForce GTX 460 (nVidia) 43 °C Hard Drives 466GB Seagate ST350041 8AS SCSI Disk Device (SATA) 35 °C Optical Drives HL-DT-ST DVDRAM GH41N SCSI CdRom Device Audio High Definition Audio Device The problem is that my Internet connection will work fine for 15 minutes or so. Then the data will just stop flowing. Windows says I am still connected, and the systray icon still shows five bars. But Comodo Firewall will stop showing up and down traffic, and another of my systray applications complains about a lack of connection. What I usually do is either disconnect from the network manually, or unplug and re-plug the USB adapter. At which point the connection will work properly for another 15 minutes. I've tried unplugging my router for 30 seconds and letting it reboot. I've also tried looking for a newer driver for my adapter but I seem to have the latest version 3.1.3.0. This is a recent problem starting about a week ago. For the previous several months things were working just fine. I haven't made any changes to my system that I am aware of. The only thing I did was open my case to blow the dust out of it, then put everything back together. How do I fix this issue?

• Changing MX records in named zone file

  - by Paul England

  I forgot how all this works. I have a GoDaddy account, using my own DNS and whatnot. I'm having trouble getting my email to work. They said I need to update my MX records. basically, I have the following. 184.168.30.42 is the domain's IP address, obviously. gamengai.com. 14400 IN NS n1 gamengai.com. 14400 IN NS n2 ns1 14400 IN A 184.168.30.42 ns2 14400 IN A 184.168.30.42 gamengai.com. 14400 IN A 184.168.30.42 localhost 14400 IN A 127.0.0.1 ftp 14400 IN A 184.168.30.42 www 14400 IN A 184.168.30.42 mail 14400 IN A 184.168.30.42 subdomain 14400 IN A 184.168.30.42 gamengai.com 14400 IN MX 10 mail Mail doesn't work though... they say to make the following change: 0 smtp.secureserver.net 10 mailstore1.secureserver.net So should the last line point to mailstore1.secureserver.net instead of mail in the last field? What about the other line? I had this working at one time, but it's totally gotten away from me. It's a virtual dedicated server and their support for this stuff is pretty bad... almost as bad as my admin skills since I went the programmer route.

• Eclipse grinds to a halt when building workspace

  - by Chris Thompson

  Hi all, This is a bit of a vague question because, frankly, I don't even know where to begin diagnosing the issue. My eclipse (Galileo) installation grinds to a complete halt when it's building the workspace -- to the point where I can't even type. I know the Android SDK I have installed is a major culprit because I can watch the memory usage go through the roof (through the built-in heap monitor) when the Android SDK content loader starts up. Every time I save a file though, the program just stops. The message at the bottom of the screen says Building workspace (74%) and sits there for about 30 or so seconds before completing and returning the performance to normal. I have a few other plugins installed (Maven, SVN, etc) but I'm assuming the main issue is Android. Has anybody had similar issues or any luck correcting this sort of problem? If there's anymore information you think would be helpful, just let me know...I didn't want to do a core dump on this question... I'm running it on Windows 7 64-bit for what it's worth. Thanks! Chris

• Ubuntu 11.10 Virtual-box Unity 3D not working

  - by naveen

  After struggling for four hours, I still cannot get Unity 3D of Gnome 3 to work on my VirtualBox - I have been pouring through Internet and forum posts but to no avail. Here's what I've done so far: VirtualBox 4.1.4r74921 on Windows 7 Installed Ubuntu Desktop 11.10 ( 32 bit ) Enabled 3D acceleration Allocated 1.5GB of RAM Allocated 50MB video memory (hope this is not the culprit) Installed Guest edition 4.1.4 Did apt-get update and apt-get upgrade Booted back in to Ubuntu - falls back to Unity 2D Shared folder, mouse integration all works, so guest edition is properly installed Tried the command and below is the output /usr/lib/nux/unity_support_test –p OpenGL vendor string: Mesa Project OpenGL renderer string: Software Rasterizer OpenGL version string: 2.1 Mesa 7.11 Not software rendered: no Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: no GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no I am trying to find what the "no" means but cannot find any good answers. Inter Core i5 processor 4GB of RAM on the host Display adapter: NVIDIA GeForce 8400GS Is anyone else facing the same problem? If so, can you point me to a solution or any reference where I can find a solution?
