• Receiving "May not have permission to edit" warning, even though I have permissions

  - by Choy

  I'm using Panic Transmit as an FTP client connecting to an Ubuntu 12.x server. When I try to edit and upload a file using it, I receive the warning that tells me to check my permissions as I may not have permissions to edit a file. I'm not setting the permissions on upload and I do have permission to edit files. After clearing the warning and checking the file on the server, may changes go through. The files I'm trying to edit are set to 775 and are part of the www-data group which my user is part of as well. Any idea why I would be getting such a prompt? This only happens on some files, not all.

• Outlook and IMAP - Outlook doesn't allow the Drafts and Trash folders to sync with the respective IMAP folders

  - by Matt

  I'm using Outlook 2007 and Outlook 2010 against an IMAP server (the problem exists across many, like Gmail, you name it). Outlook lets you set your Outlook "Sent" folder to map to the IMAP server's Sent folder (the other choice is to map your Outlook Sent to your Personal Folders Sent) - this is good. When you send a message from Outlook and then look in the sent folder of the IMAP server (e.g. from a different client or from a browser), the messages are there. This is the behavior I want. Outlook does NOT support the same behavior for Drafts and Trash. In both cases, items deleted (or Drafts saved) in Outlook go in to Outlook's local folders and do NOT show on the IMAP server's Trash or Drafts folders. Same problem in reverse. Thunderbird on the other hand does support the proper mapping of Drafts, Sent and Trash. I expected this to be IMAP-specific but it appears to be client specific. What does Outlook implement it this way and is there a workaround?

• LAMP stack security question - uploading files to server

  - by morpheous

  I am running Ubuntu 9.10 desktop on my home machine. I need to upload files from my local machine, to my web server, on a periodic basis. My server is running Ubuntu Server LTS. I want my server to be secure, and only run the LAMP stack and possibly, an email server. I do not (ideally) want to have FTP or anything that can allow (more) knowledgeable hackers to be able to hack into my server. Can anyone recommend how I may send files from my local machine to the server? This may seem an easy/trivial question, but I am relatively new to Linux - and I got my previous Windows server machine serious hacked in the past, hence the move to Linux, and thats why I am so security conscious.

• Unable to login to Amazon EC2 compute server

  I am unable to login to the EC2 server.

• How to find the static ip address of my router?

  - by OSX NINJA

  I bricked my Linksys WRT54GS router when trying to change the firmware on it from dd-wrt to open-wrt. In order to unbrick it, I need to be able to do an ftp transfer to it. The problem is that it isn't using DHCP addressing and I can't just use the default ip address of 192.168.1.1. I have to use the ip address it was set at before it got bricked. The problem is I forgot what that number was. Is there some program or script that can find it out?

• Symantec Endpoint Protection Virus Definitions

  - by Gus Denton

  I have done some Googling but I cannot get a definitive answer certainly not from the Symantec KB. I have a Virtualised Win 2003R2 server 32bit. It has been provisioned to me with Symantec Endpoint Protection 11.0.62xxx CLIENT (not a definitions server) the directory C:\Program Files\Common Files\Symantec Shared\VirusDefs is 750MB IT doesn't contain .tmp directories so it is NOT a corrupt definitions server. IT does contain directories named with a date pattern YYYYMMDD.xxx Some of these folders are 12 months old and I would like to recover the space. The sysmantect forums are full of this stuff but a lot of the postings contain links back to documents that are not specific to End Point Protection Client. It appears that I should be able to delete the older folders and all will be OK. with a service restart however there is a warning about having Live Update Administrator Installed Firstly I have no idea if I have this installed how to I check and secondly can I just ditch these old files and restart ? Regards Gus Denton Learning and Teaching Uni of New South Wales Sydney Australia For those trying to assist me I thankyou. I have followed some instructions found on the Symantec site and assumed that the response from Nixphoe would resolve my issue. It appears that as I am on a provisioned VM from a central IT unit I cannot run the Symantec commands from the Run prompt as my admin creds to get me in. (smc -stop) Basically I need to claw back some Diskspace from the c: drive which is being filed up with WSUS patches and Symantec files. I have managed to delete one symantec cache through the live update control panel and recovered 470Mb I suppose my last question for those more experienced than myself is, can I simply remove say the two oldest virus definition folders without completely foobaring the End Point protection and the server ? Regards Gus

• Securing a Windows Server 2008 R2 Public Web Server

  - by Denny Ferrassoli

  I'm setting up a public web server: Windows Server 2008 R2, IIS7.5. Does anyone have a tutorial / walkthrough / tips on properly securing a public web server? I've seen a few tutorials but mostly focused on Windows Server 2003. What I've done so far: Created a specific user account for the website / app pool, Renamed Admin account, Installed FTPS, Configured firewall to block any non-public service (web / https), Configured firewall to allow access to management interfaces only from specific IP addresses (rdp, IIS management, ftp) Maybe a few other things but can't remember at the moment... ICMP is allowed... Should I disable all except ping? Port scan reveals only web and https ports. Any other suggestions? Thanks

• Windows Server 2008 32 bit & windows 7 professional SP1

  - by Harry

  I'm testing my new Windows Server 2008 32 bit edition (2 servers) as a server and Windows 7 professional 32 bit as a client. Let say one is a primary domain controller (PDC) and the other is a backup domain controller (BDC) like the old time to ease. Every setup were done in the PDC and just replicate to BDC. Didn't setup anything, just install the server with AD, DNS, DHCP, that's all. Then I use my windows 7 pro 32 bit to join the domain. It worked. After that I tried to change the password of a the user (not administrator) but it always failed said it didn't meet the password complexity setup while in fact there's no setup at all either in account policy, default domain policy or even local policy. Tried to disable the password complexity in the default domain policy instead of didn't set all then test again but still failed. Browse and found suggestion to setup the minimum and maximum password age to 0 but it also failed. Tried to restart the server and the client then change password, still failed with the same error, didn't meet password complexity setup. Tried to see in the rsop.msc but didn't found anything. In fact, if I see the setup in another system with windows server 2003 and windows xp, using rsop.msc I can see there's setup for computer configuration windows settings security settings account policies password policy. I also have a windows 7 pro 32 bit in a windows server 2003 32 bit environment but unable to find the same setting using rsop but this windows 7 works fine. anyone can give suggestion what's the problem and what to do so I can change my windows 7 pro laptop password in a windows server 2008 environment? another thing, is it the right assumption that we can see all the policies setting in windows 7 whether it's in a windows server 2003 or 2008 environment? thanks.

• How do I maximize and check my gigabit transfer rate?

  - by J Penguin

  I'm trying to maximize my LAN transfer speed. LAN cards and switch are all gigabit on a CAT 6 cable. Modes are set correctly to 1000 full duplex. CentOS server Testing with ftp from both windows and fedora, I'm only having the speed around 11MB/s. On windows I notice that the first few seconds of file transfer I'm actually getting around 25MB/s before it drops to 11MB/s Can anyone please recommend me what my next step should be to increase this performance? Are there any utilities I can use to test the file transfer speed without taking hard drive speed into consideration? The only thing I know is the MTU which I will have to wait until the office hour is over before I can play with it. If there are anything else I should be aware of, please please let me know. Thank you!

• Top ten security tips for non-technical users

  - by Justin

  I'm giving a presentation later this week to the staff at the company where I work. The goal of the presentation is to serve as a refresher/remidner of good practices that can help keep our network secure. The audience is made up of both programmers and non-technical staff, so the presentation is geared for non-technical users. I want part of this presentation to be a top list of "tips". The list needs to be short (to encourage memory) and be specific and relevant to the user. I have the following five items so far: Never open an attachment you didn't expect Only download software from a trusted source, like download.com Do not distribute passwords when requested via phone or email Be wary of social engineering Do not store sensitive data on an FTP server Some clarifications: This is for our work network These need to be "best practices" tips for the end-user, not IT policy We have backups, OS patches, firewall, AV, etc, all centrally managed This is for a small business (less than 25 people) I have two questions: Do you suggest any additional items? Do you suggest any changes to existing items?

• Configuring OS X L2TP VPN to use Certificate for IPSEC layer instead of Pre Shared Key

  - by Matthew Savage

  I'm trying to setup a L2TP VPN on an OS X Snow Leopard Server setup, and have had success using a pre-shared key, however I would rather not rely on a simple string, and use a certificate instead. Setting this up on the server side is seemingly easy, you simply select a certificate you have generated from the list, and hit apply, however when I try to use the certificate on the client side it fails. I have exported the certificate into a P12 file, and then transferred to the client, and imported into the login keychain, however when I try to choose the certificate (from Network preferences, clicking Authentication Settings, then selecting Certificate and pressing Select) I am shown the following error: No machine certificates found Certificate authentication cannot be used because your keychain does not contain any suitable certificates. Use Keychain Access to import the certificate into your keychain. If you do not have the certificates required for authentication, contact your network administrator. Unfortunately even when I try to generate a certificate where I override the defaults, ensure the DNS name etc are set properly this doesn't change. When I select Certificate Authentication for the User Auth, and click Select the certificate for the server shows up there, but obviously this isn't where I need it to be available.

• FreeBSD Can't recognize my network

  - by Mascarpone

  I'm trying to install FreeBSD on VirtualBox in my Ubuntu 11.10 . When I try to download the packages via FTP, the systems fails to correctly configure the DHCP. There are two possible behaviors, randomly picked every time I retry: The DHCP is almost correctly configured, except my host is .fastwebnet.it rather than the real namehost.fastwebnet.it . Whenever I try to add something before the . , the system edit the field and revert it to .fastwebnet.it Only the netmask is configured, everything else is blank. I can't edit the fields. I tried both with NAT and Bridged adapter in my VirtualBox settings.

• LogMeIn Hamachi for Linux

  - by tlunter

  So far most of my work using LogMeIn Hamachi has been from either a Mac OS X or Windows system to Windows or a Linux Computer. Recently I purchased a mini computer and have been running Ubuntu Server on it, as my little server. I knew LogMeIn had a Linux client that is command line only, but I often do all my work via command line anyway, so that wasn't an issue. I added my user to the correct local file so that I could run the hamachi daemon without sudo, and was able to connect to LogMeIn's service. I decided to set up my Linux server as a git server as well, and set it up correctly. The thing is, the server is behind my schools firewall and I need to use hamachi to get around that. Since most of the time I was using either Mac or Windows, I never had an issue sshing onto any of my computers since LogMeIn is fully featured for these OSs. From Linux (Arch) though, it seems like the client cannot correctly route to the LogMeIn IPs. I know from Windows I can connect to the Linux computers, both of them. From Linux (Arch) though, I can't connect to my Mac, Windows, or Linux server. It keeps just dropping the connection. I was wondering if there was some configuration that I would need to make for this to work. I understand that it is most likely going to be a static configuration since I assume it has to do with the computer not understanding that 5.*.*.* actually refers to another IP:Port. Has anyone had any experience getting this to work?

• development server?

  - by ajsie

  for a project there will be me and one more programmer to develop a web service. i wonder how the development environment should be like. cause we need central storage (documents, pictures, business materials etc), file version handling, lamp (testing the web service) etc. i have never set up an environment for this before and want to have suggestions from experienced people which tools to use for effective collaboration. what crossed my mind: seperate applications: - google wave (for communication forth and back, setting up guide lines, other information) - team viewer (desktop sharing) - skype (calling) vps (ubuntu server): - svn (version tracking) - ftp (central storage) - lamp (testing the web service) - ssh (managing the vps) is this an appropriate programming environment? and regarding the vps, is it best practice to use ONE vps for all tasks listed up there? all suggestions and feedbacks are welcome!

• Authenticating Active Directory Users to Mac OS X Mavericks Server L2TP VPN Service

  - by dean

  We have a Windows Server 2012 Active Directory Infrastructure that consists of two domain controllers. Bound to the Active Directory Domain is a Mac OS X Mavericks Server 10.9.3. The server runs Profile Manager and VPN Services. My Active Directory users are able to authenticate to the Profile Manager, but not the VPN. I have found several threads on other forums of other users reporting similar issues, here is just one of many references: https://discussions.apple.com/thread/5174619 It appears as though the issue is related to a CHAP authentication failure. Can anyone suggest what next troubleshooting steps I might take? Is there a way to liberalize the authentication mechanism to include MSCHAP? Here is an excerpt of the transaction from the logs.

• Googlebot repeatedly looks for files that aren't on my server

  - by John at CashCommons

  I'm hosting a site for a volunteer organization. I've moved the site to WordPress, but it wasn't always that way. I suspect at one point it was hacked badly. My Apache error log file has grown to 122 kB in just the past 18 hours. The large majority of the errors logged are of this form -- it's repeated hundreds of times today alone in my log files: [Mon Nov 12 18:29:27 2012] [error] [client xx.xxx.xx.xxx] File does not exist: /home/*******/public_html/*******.org/calendar.php [Mon Nov 12 18:29:27 2012] [error] [client xx.xxx.xx.xxx] File does not exist: /home/*******/public_html/*******.org/404.shtml (I verified that xx.xxx.xx.xxx was a Google server.) I suspect there was a security hole somewhere before, likely in calendar.php, that was exploited. The files don't exist anymore, but there may be many backlinks that exist that reference here, hence why googlebot is so interested in crawling them. How do I fix this gracefully? I still would like Google to index the site. I just want to tell it somehow not to look for these files anymore.

• How do I delete the Windows Explorer address bar history

  - by mlissner

  Note: I am NOT referring to Internet Explorer. I am using Windows XP and Windows Server 2008 and need to delete the history values from the file browser (aka Windows Explorer). Somebody put a password into the address bar as ftp://user:pass, and now I can't delete the value. Some forums say to delete this registry key: HKEY_CURRENT_USER\Software\Microsoft\Windows\Curre ntVersion\Explorer\TypedPaths In Windows XP, the key doesn't exist, and in Windows Server 2008, the key is there, but deleting it doesn't seem to help. Any help?

• Mysql Cluster not working on Ubuntu

  - by user53864

  I am unable to setup MySQL Cluster on ubuntu servers. As a starting point I started from the link but I am not successful and the tar ball version I download is 6.3.45. As I wanted to test the mysql cluster, the Data node and SQL node are same but sql never appeared as connected in management node console and it looks like below. [ndbd(NDB)] 2 node(s) id=2 @192.168.1.107 (Version: version number, Nodegroup: 0, Master) id=3 @192.168.1.108 (Version: version number, Nodegroup: 0) [ndb_mgmd(MGM)] 1 node(s) id=1 @192.168.1.105 (Version: version number) [mysqld(API)] 2 node(s) id=4 (not connected, accepting connect from 192.168.1.107) id=5 (not connected, accepting connect from 192.168.1.108) On all the 3 machines mysql-server & client(apt-get install mysql-server mysql-client) were already installed and I completely stopped and also removed them at the system start up. Now the mysqld is from extracted cluster tar ball(/usr/local/mysql/support-files/mysql.server). As for testing, I created a test database on both the data nodes but the tables are also not syncing on other node. I checked many links, configurations are remained similar in all the links but somewhere it's going wrong. Anymore extra package is required?, Could anyone help me here..?. I am trying this for past 3 days... Thank you!

• How to auto-cc a system email account any time a user creates an appointment

  - by Ferdy

  I will not bother explaining my full architecture or reasons for wanting this in order to keep this question short: Is it possible to auto-cc a certain email account any time a Exchange user creates an appointment or meeting in his own calendar? Is it possible using rules? Our Exchange 2007 server is outsourced, I cannot change the configuration or install plugins server-side Preferably, it still should work server-side, because users may use the Outlook client but also Outlook Web Access Is there any other way, perhaps using group policies? My conclusion so far is that the only viable way to accomplish this is to build an Outlook add-on. The problem there is that it will need to be managed for thousands of desktop users and that the add-on will not work when using another client (OWA, mobile). An alternative architecture could be to pull the information from the user's calendar on a scheduled basis. Given that we are talking about a lot of users, scalability is a major issue, this has also been confirmed by Microsoft. Can you confirm that my thinking is correct or do you have any other solutions?

• Development Server Blocked Only from Home

  - by theonlylos

  Recently I've been having an issue with my CentOS 6 test server running Apache and Webmin running on port 10000 where when I try accessing any part of the server - SSH/FTP and even my domains (I have two - both keep getting timeout errors) when I try accessing from any computer on my home network. However when I access via tethering or via my office networks everything loads fine. While the firewall is the first issue at mind, my router never was set to block any special ports, and even after adding port 10000 as a specific exception I'm having no luck. Also, I doubt this is an IP blacklisting issue because I have websites on other servers using CloudFlare for security and I haven't gotten any warnings. Any assistance is greatly apprecaiated. UPDATE: Just some extra details about the issue: My ISP to my knowledge only blocks off ports 25 and 80 for residential users to prevent them from running web servers - however this issue has only come up a day or two ago, before that I was using the server successfully for months. Also the server is not physically located in any of my workspaces - it's a VPS housed in a datacenter

• Unknown Host Error, is this a registrar problem or a host problem?

  - by jerrygarciuh

  Hi guys, I am dealing with a barrel of weasels on this one. Ad agency registered the domain in mid-August with Network Solutions. 72 hours ago I updated the DNS to point to a host provided by an associate of the client whose credentials are dubious. The DNS servers are at NETSONIC.NET (NS1 and NS2) and respond to ping no problem. I can FTP to the server using its IP but the name is no go. The name is also no go for tracert and ping: tracert voodoobbqfranchise.com Unable to resolve target system name voodoobbqfranchise.com. ping voodoobbqfranchise.com ping: unknown host voodoobbqfranchise.com I called NetSol and of course their tier one guy swears it must be the host but I insist that an unknown host must be a NetSol issue. Otherwise we'd get somethng like an httpd_conf error after being routed to the Netsonic server. Am I right? Is this an issue at the registrar? TIA JG

• Python2.7 / Pip2.7 install in Centos6: root does not see /usr/local/bin

  - by Erotemic

  I am trying to install Python2.7 in Centos 6. It's a pain as centos6 ships with python26 and yum is dependent on it. Furthermore yum does not seem to have python2.7 I ended up building it from source: wget https://www.python.org/ftp/python/2.7.6/Python-2.7.6.tgz gunzip Python-2.7.6.tgz tar -xvf Python-2.7.6.tar cd Python-2.7.6 ./configure --prefix=/usr/local --enable-unicode=ucs4 --enable-shared LDFLAGS="-Wl,-rpath /usr/local/lib" make sudo make altinstall cd ~ This installed python2.7 to /usr/local/bin and I can use it. But I cannot call it with sudo unless I specify the whole pathname To install pip I had to do: wget https://bootstrap.pypa.io/get-pip.py sudo /usr/local/bin/python2.7 get-pip.py Now whenever I want a package I have to call sudo /usr/local/bin/pip2.7 install somepackage Is there a clean way to be able to run: sudo pip2.7 install somepackage without having to specify the absolute path? Is a symlink into /usr/bin safe?

• VMware ARP/Mac Networking

  - by Ross Wilson

  Hi Guys, I am very interested in how VMware networking works. I have scoured the VMware website and read their data sheets, this has given me some basic knowledge. I now have some questions. Lets assume that we have a physical server running the VMware hypervisor. The physical server is running a Virtual Machine. The physical box has one physical NIC. The NIC is connected to a switch, as so is a desktop client. Now, this is where my first question lies. The VM has an IP address: 192.168.1.1. How do desktop clients on the network communicate with this VM? So, the client pings 192.168.1.1. The ping packet is sent to the switch. The switch checks its MAC address table and sees that 192.168.1.1 is associated with the MAC address of the physical NIC. Correct? I then assume that the ping packet is sent to the server's physical NIC, where the hypervisor routes the packet to the VM thats using 192.168.1.1? Please could you give me a run down as to how VM networking works? Many thanks, Ross
