• How can I figure out which PHP extensions aren't being used?

  - by Tom Marthenal

  I manage a server (running Ubuntu) which hosts our client's sites with a few dozen different PHP-based websites, mostly small sites but also some installations of CMSes and forums. I used the get_loaded_extensions() method to see what extensions I have loaded. To help streamline the server (remove unnecessary extensions to make upgrading easier and marginally improve speed), I'd like to remove extensions that aren't being used by any of the sites. I currently have 54 different extensions loaded. I can easily eliminate some of these from the list which I know are used, but others I am less sure about. Is there some way that I can see extensions which have not been used recently?

• Cannot use `su` or `sudo` after set up key-based access to SSH

  - by OrangeTux

  I'm following this tuturial to setup key-based access to the SSH I created a user. I add copy the key to the client via ssh-copy-id <username>@<host> Becasuse ssh <username>@<host> still prompts for a password I run ssh-add on the local machine. The terminal doens't prompt for a password, I can login without using a password. But I cannot run su anymore. Every input for the password results in Authentication failure. I tried it again. But before coping the key, I added to the sudoer file. Copied key, ssh-add. But now I cannot login to my SSH shell att all? How can I setup a key-based SSH access with the possibiluty to use su or sudo?

• formatting a column based on another columns cell TEXT not value in excel

  - by lisa

  I have dates that are running off a formula in that column based on information it is collecting from other worksheets. I have another column that lists text answers based on a different formula that that column is running. It is a customer list that runs with names going down page and multiple columns of information for each client running across page What i want to do is: If column j says "paid" then turn column m - same row - a color or border or something I will repeat this formula for the various things that j can say, just cant figure out how to make conditional formatting read j to change m. To complicate things, in addition to the formula running to collect the date in m, there is also a conditional format set up for m that changes the color of the cells after a certain date. I want to be able to keep that formula, in addition to the one that you are assisting with...i will use highlighting, or something different to avoid any conflicts.

• routing problems

  - by user174050

  I have an windows 7 laptop and I have installed openvpn 2.2x as client. The laptop has 2 ethernet cards, one of them is wireless. The wireless lan is 192.168.1.0/24 The Fix lan is 192.168.2.0/24 If I connect to the openvpn server useing the Fix lan the I can connect properly and for testing I ping to my openvpn server 10.0.0.1 that answers correctly. But if I connect to the openvpn server useing the wireless lan, I can establish the connection but pinging to the server isn´t possible. The packets goes allways lost. Why can this happen? In an other laptop where windows xp is installed and with the same lan configuratio everything works propperly. In both cases the firewall is configured to access the vnc server and the server directories useing samba. With the XP I have no problems. I will thank you for all help Ignacio

• How can I get a notification from my server if the mail queue stops

  - by Ash

  I am using QMail with Plesk 10 on an Apache server. Occasionally the mail queue stops processing emails - this most recently happenend when an email account got hacked and started sending hundreds of emails. We did not find out about this until a client of ours contacted to say that their emails were not being recieved, so we checked the mail queue and lo and behold the service had stopped. In future I would like to be notified when the mailqueue stops. How can I set something up so the server will run a command whenever the mailqueue stops?

• preloading RSS contents in thunderbird, before actually reading them

  - by Berry Tsakala

  i have thunderbird 3.x, and i'm subscribed to several RSS feeds. How can I tell thunderbird to load/download any new RSS items in the background? The usual behavior with RSS feeds is that it download the headrs, or few introductory lines from the contents, but only when i'm clicking a feed item it starts loading "for real". I really want to receive the feeds and not to wait for them to load, the same way i receive emails in any email client - all messages are fully downloaded at once. there could be several reasons, BTW. - e.g. if i have short connection time, i'd rather connect, sync everything at once, and read it later. - or if i have a slow wifi connection, it's annoying to wait for each and every message, but the computer is idle while reading.. thanks

• JBoss behind NAT hostname problem

  - by z0mbix

  My company has a JBoss cluster sitting behind a firewall that performs NAT. We forward ports to JBoss from the firewall, so that our client application can access the server. We are having trouble when JBoss replies it tells the clients to connect to the internal hostname, not the external one with which the initial connection was made. Is this something that is easily resolved/configured? How are other JBoss app servers configured behind NAT firewalls? Split-horizon DNS? Many Thanks

• Sending Emails from existing SMTP host from Ubuntu Server

  - by ezgoodnight

  I feel like my problem is very simple, but I've been trying for quite some time and haven't cracked it. You experienced server guys will probably laugh at this, but I'm finally at the point I need help or I'll never get anywhere. I have a little box running 12.04 LTS and I've wanted to script some status checks and have the server send me an email and schedule this with cron. I basically want a command line mail client that I can set up as easily as Thunderbird to send through my existing SMTP through the command line. Something that can easily be rolled into my bash scripts. I already have a remote host handling our email, SMTP, MTA, all that garbage. I don't particularly want to set up a relay just to send email when I have one that everyone else in the company already uses. I've tried, but there are too many aspects I don't understand AND I don't see why I should set up something local when we already pay for a remote host to do these things. If I absolutely have to set up sendmail or postfix, then so be it, but I'd appreciate a simple alternative. I'm open to practically anything at this point.

• Cannot access Samba Share that is on Linux

  - by doug

  I have 3 virtual machines; Windows Server 2012, Windows 8, and CentOS Linux. The Server is configured with active domain. The CentOS VM has a Samba Share which has rights for the domain Administrator. Now, the Windows Server 2012 DC can successfully locate the share, but cannot access it (with Admin) ? Is it not possible for the Server to have access to it has Domain Client Admin, not Server Admin ? Hope this is clear? Thanks

• Lotus Notes won't open a hyperlink/uri in a browser!

  - by Andy O

  I'm still new to Lotus, but I have LN 8.0.2, and have it set up to open hyperlinks "using the browser i have set as the default for this operating system" which in my case is Firefox 3.6.13. If I try to select "use the browser embedded in this client" then it just forgets it after I click save (ie if i go back into preferences it's reset to the default for this operating system option) Windows XP SP 3. Whenever I click on a link in an email...memo... then it does nothing and flashes an underscore underneath it. It's so basic and so annoying there must be something I'm missing. Any help please!

• Alternatives to time tracking methodologies [closed]

  - by Brandon Wamboldt

  Question first: What are some feasible alternatives to time tracking for employees in a web/software development company, and why are they better options Explanation: I work at a company where we work like this. Everybody is paid salary. We have 3 types of work, Contract, Adhoc and Internal (Non billable). Adhoc is just small changes that take a few hours and we just bill the client at the end of the month. Contracts are signed and we have this big long process, the usual. We figure out how much to charge by getting an estimation of the time involved (From the design and the developers), multiplying it by our hourly rate and that's it. So say we estimate 50 hours for a website. We have time tracking software and have to record the time in 15 we spend on it (7:00 to 7:15 for example), the project name, and give it some comments. Now if we go over the 50 hours, we are both losing money and are inefficient. Now that I've explained how the system works, my question is how else can it be done if a better method exists (Which I'm sure one must). Nobody here likes the current system, we just can't find an alternative. I'd be more than willing to work after hours longer hours on a project to get it done in time, but I'm much inclined to do so with the current system. I'd love to be able to sum up (Or link) to this post for my manager to show them why we should use abc system instead of this system.

• Permission denied on network share

  - by Philipp

  i have a Windows 8 host system running a virtual(hyper-v) Debian6 client with an lamp environment. My development environment runs under Windows and I mapped the folder with my php files to a network drive so Apache has access to them.(mount.cifs //pc/share /var/share/) This far no problems - I see my app on windows in the browser. The problem is, I can't write stuff in php to the share folder - everytime i got a permission denied message in my error logs. For testing purpose i tried to change the directory permissions of /var/share with chmod -R 777 /var/share without success. Now Iam a little bit stumped.. has anyone an idea how to solve this?

• Why is file sharing over internet still working, despite all firewall exceptions for filesharing being disabled?

  - by Triynko

  Every exception in my windows server firewall that starts with "File and Printer Sharing" is disabled (ordered by name, so that includes domain, public (active), and private profiles). The Network and Sharing Center's options for everything except password protected sharing are off. Why would I still be able to access a network share on that server via an address like "\\my.server.com\" over the internet? The firewall is on for all profiles and blocking incoming connections by default. A "netstat -an" command on the server reveals the share connection is occurring over port 445 (SMB). I restarted the client to ensure it was actually re-establishing a new connection successfully. Is the "Password protected sharing: On" option in Network and Sharing Center bypassing the firewall restrictions, or adding some other exception somewhere that I'm missing? EDIT: "Custom" rules are not the problem. It's the "built-in" rules for Terminal Services that was the problem. Can you believe port 445 (File Sharing Port) has to be wide open to the internet to use Terminal Services Licensing?)

• Exchange over HTTP

  - by Rob

  I have recently setup a brand new install of SBS 2011 and it is working well. Exchange is running as advertised and all users are happy. Now, there are 2 users who would like to work outside of the office and require email setting up in Outlook. No problem - Exchange over HTTP. However for some reason it's not working. They can access Outlook Web Access okay, but for some reason Exchange over HTTP / HTTPS isn't working. The error message I receive in Outlook is: "The name cannot be resolved. The connection to Microsoft Exchange is unavailable. Outlook must be online or connected to complete this action." I've tried temporarily turning off the Firewall on both the server and the client but this doesn't help at all. Is there something I'm missing or is there a permission that needs enabling to allow Exchange over HTTP to work?? Many thanks

• Some strange things in the db table of mysql database

  - by 0al0

  I noticed some weird things in the db table of mysql database in a client's server, after having the Mysql service stopping for no reason what are the test, and test_% entries? Why are there two entries for the database AQUA? Why is there a entry with a blank name? Should I worry about any of those? What should I do for each specific case? Is it safe to just delete the ones that should not be there, after backing up?

• Windows 2008 R2 Not resolving IP's or domains

  - by InsaneAR

  I have two servers with Microsoft Windows Server 2008 R2 x64, and today I realized that one of them don't resolve IP's or domain names. If I ping the same machine IP, it respond, but if I ping an external IP (like 8.8.8.8 or any other) it does not work. The same with domain names. At Windows Event Viewer I'm having Warning 1014: Name resolution for the name timed out after none of the configured DNS servers responded THE SERVER HAS CONNECTIVITY, I'm connected remotely and the services and incoming traffic (like FTP, etc) are working OK. Things I've done & tested: Run Kaspersky Virus Removal 10 Restart/Turn off the DNS Client service Clean the hosts file Reboot the server Turn off the Windows Firewall (there's not another firewall) Quit or replace the current DNS servers I just can ping the same machine IP or the gateway! Can anybody help me?

• What are possible reasons why a calendar entry in OWA is at a different time than in Outlook?

  - by Ken Pespisa

  We have two Exchange 2003 servers, our primary server and a front-end server that hosts Outlook Web Access (OWA). When I open my boss' calendar via Outlook 2007 (from my Outlook client as well as hers) I see the event scheduled for 10:30 am. When I open her calendar via Outlook Web Access, the same event is scheduled for 4:30 am. I don't understand Exchange well-enough to imagine how this is possible. If you have any ideas why this could be happening, I greatly appreciate it. I'd also very much appreciate any insight you have to how this could be possible. There must be some cached data on the front-end server that causes the calendar entry to appear at a different time, I suppose. Any insight into how Exchange manages that cache and where I could look for an issue would be very helpful. Thank you!

• Cannot access internal website after being connected to other network

  - by Dandroid

  I have a client who claim they cannot access their internal website when they have e.g. been out traveling. They have to reset their browser settings every time to be able to get access again. As they live on another continent and timezone it's hard for me to run live tests with them to see what changes in their browser settings. My first guess would be it's some sort of Proxy related issue, but I want to know if there could be other reasons for this? It's not the LAN itself, that we are sure of. It's browser specific only. Edit It's worth mentioning that it only happens when they turn off/restart their computers.

• SSL issues with puppet agent at openSUSE

  - by Roman Grazhdan

  I have a master running at my vps, and it has a simple helloworld manifest which works fine with any ubuntu machine I have. It connects, exchanges keys and creates test file allright, so I'm sure it's not server issue. The agent which is running at a virtual machine with openSUSE says: err: Could not request certificate: SSL_connect returned=1 errno=0 state=SSLv3 read server certificate B: certificate verify failed. This is often because the time is out of sync on the server or client I believe it's probably a broken or missing lib, since the package is not built very accurately - it wouldn't start out of the box because of wrong path to lockfile, for example. So how do I figure out what exactly is wrong here? The time is allright, I've checked it. I probably could do without SSL if it's possible, since that SUSE machines are just for training, but it's the last opportunity.

• How do I transfer .pst e-mails from Outlook to a Mac e-mail program?

  - by user46248

  New Macbook Pro came in yesterday with MS Office Outlook crashes consistently on importing from .pst after about 30 seconds. I see a EXC_BAD_ACCESS and something about CF get string length or the like. Tried 2 different .pst files created on different dates of different folders. Mail and Thunderbird lack options for importing from .PST. I can export to .csv but still didn't see an option for importing that. How can I get my .pst files into an e-mail client on the Mac?

• How can I fix the #c3284d# malvertising hack on my website?

  - by crm

  For the past couple of weeks at semi regular intervals, this website has had the #c3284d# malware code inserted into some of its .php files. Also the .htaccess file had its equivelant code inserted. I have, on many occasions removed the malicious code, replaced files, changed the ftp password on my ftp client (which is CoreFTP), changed the connection method to FTPS for more secure storage of the password (instead of plain text). I have also scanned my computer several times using AVG and Windows Defender which have found no malware on my computer which might have been storing my ftp passwords. I used Sucuri SiteCheck to check my website which says my website is clean of malware which is bizarre because I just attempted to click one of the links on the site a minute ago and it linked me to another one of these random stats.php sites, even though it appears I have gotten rid of the #c3284d# code again (which will no doubt be re-inserted somehow in an hour or so).. Has anyone found an actual viable solution for this malware hack? I have done just about all of the things suggested here and here and the problem still persists. Currently when I click on a link within the sites navigation menu within Google Chrome I get googles Malware warning page: Warning: Something's Not Right Here! oxsanasiberians.com contains malware. Your computer might catch a virus if you visit this site. Google has found that malicious software may be installed onto your computer if you proceed. If you've visited this site in the past or you trust this site, it's possible that it has just recently been compromised by a hacker. You should not proceed. Why not try again tomorrow or go somewhere else? We have already notified oxsanasiberians.com that we found malware on the site. For more about the problems found on oxsanasiberians.com, visit the Google Safe Browsing diagnostic page. I'm wondering if it is possible that the Google Chrome browser I am using has itself been hacked? Does anyone else get re-directed when clicking links on the the website?

• Whats the best way to deal with backups for my php/mysql application

  - by spirytus

  I'm creating php application for my client and now thinking what would be the best way to do backups, automatically if possible? I don't have much experience in this area and in case something goes wrong, or if I need to migrate, I would like to have fast way of getting it all back online. I understand "something goes wrong" is a very wide term, but lets say that someone hacks my site and wipes out database and all the files. My app. is written in php/mysql and I got access to cpanel (hosted with justhost.com if that makes any difference :). I used Joomla and it has JoomlaPack that does complete backup almost automatically and in case site fails, its easy to revert, or migrate if necessary. Is there anything like that for my configuration that would make reverting/migration, easy?

• Boot camp install from a HDD image

  - by Dombou

  How would one go about imaging an old work computer (old IBM aptiva from 2001ish) with Windows XP and lots of stuff (VPN client with settings etc) to a new iMac, while preserving Mac OSX? I can't simply install XP on the iMac and then reinstall/copy across stuff; it NEEDS to be an image. Can you even image smaller HDD's and then place them on large ones, or do they have to be the same size? Recommendations on how I go about this? Edit: It MUST be boot camp. I don't want to virtualize it from within OsX

• Extend university wifi network

  - by asfasdoiuh ouhouhouh

  i live in a university campus and i can get wifi signal on the outside of my window but not in the house. The solution i use at the moment is a usb wifi dongle outside connected to my laptop but the lack of an internal antenna make the connection quite unreliable at times. So i was trying to find another solution to improve the reception of my network. One idea is to setup a router on the outside (in a place with stronger signal) and redirect the connection inside the house with an ethernet cable but the problem is that our Uni Wifi is managed by a capitve portal (BlueSocket with DNS redirection to login page) and the authentication has to happen on the mac address that connect to the net (so the client appliance in this case). If I use a router with Mac-Clone capability i will be able to be redirected trough the captive portal on my laptop computer and login from there or i need to setup my router to fill in the login page by itself? There are other hardware/software solutions i can use to get what i want?

• Win Server 2008 R2 - Mapped shared folder hanging?

  - by M-Tech

  I have recently built a windows 2008 server R2 machine. This is purely for file server purposes and is very much a basic build. All windows updates installed and part of domain. I have setup a shared folder on the C:Drive and added permissions for domain users as co-owners. The client machines run XP SP3 and are part of the domain also. We have a few servers running the same setups on a few of our sites but this one is particular crashes users machines (explorer.exe hangs for at least a few mins) when attempting to access the shared folder. I have turned off the option on the network card for power save aswell still no change. Any help with this is very much appreciated and i look forward to hearing from you ;)
