• Fresh Red Hat Enterprise Linux fails to install httpd using yum

  - by Julian

  I'm trying to install a LAMP stack in a fresh red hat server but yum is misbehaving. Being linux illiterate I'm at a loss. $yum install httpd Loaded plugins: security Setting up Install Process No package httpd available.

• Is there a taskbar for OS X?

  - by Paul Biggar

  I'd like to permanently see a clickable list of windows I have open, in the same way that the taskbar allows in Windows. Can I do this on Mac? Some details: i have many virtual desktops (spaces), so often a single application has windows on many of them. I often have multiple windows of each application, such as the terminal or browser, on the same virtual desktop I have multiple monitors, if it matters. Edit: When I say 'permanently see a clickable list of windows I have open' I mean that I want to see every window I have open, and I'd like to be able to click on each one to open that window. I'm not looking for the newer behaviour where tasks are clustered by application.

• Pfsense: Inbound Load Balancing https with sticky connection

  - by Zeux

  first of all I'm very sorry for my English... This is my scenario: Internet Firewall+LB: pfsense_1(Active) + pfsense_2(Passive) in CARP Pool servers: 3 x nginx(PHP5+HTTP+HTTPS) Pfsense 1 and 2 CARP configured with Virtual IP (pubblic). Nginx servers's ips are all private. I want to load balance inbound HTTP and HTTPS connections between the 3 nginx web servers. An importat thing is that the HTTPS connections must be "sticky connections": in HTTPS connections, after login by username and password, I setup a php session and therefore when a client starts a HTTPS connection it will be always redirected to the same nginx server, until it disconnects itself, it closes the page/browser or after a timeout (30minutes?) without activity. Is this possible whit the last release(2.0.1) of pfsense? thank you very much...

• gzip not working for some files using nginx

  - by shakalandy

  Some files are not gzipped on their way to the user browser in our setup. for example http://myhostname.com/css/build/20120904-1.css http://myhostname.com/js/dojo/dn/main.js?20120904-1 http://myhostname.com/js/jquery-min/compiled.js?20120725-4 can not be zipped. my current configuration: location ~* \.(js|css|png|jpg|jpeg|gif|ico)\.*+$ { if ($args ~ [0-9]\.*+) { expires max; break; } expires max; log_not_found off; gzip on; } What needs to be adjusted to make gzip fly? I already tried several other options but don't want to continue with try&error on this. Thank you very much.

• Brightness keeps changing in Windows 8.1 (on Macbook Pro Retina)

  - by gzak

  Before anyone gets too excited, it's not the "Adaptive Brightness" feature of the OS. I've already turned that off. Also it seems to have nothing to do with ambient light. It actually seems to do with the average "color" of the display. If I'm working in dark-themed Visual Studio, the brightness "pops" brighter. When I switch to the browser, it "pops" darker. So it's kind of adaptive brightness based on average pixel color (or something like that). What makes it rather annoying is that the brightness pops, rather than transitioning gradually. What is this feature, and how do I disable it (or at least make it smoother)?

• Remove CGI from IIS7

  - by jekcom

  I ran some security scan and the scan said that all kind of CGI stuff are potential thread. This is part of the result : (ash) is present in the cgi-bin directory (bash) is present in the cgi-bin directory By exploiting this vulnerability, a malicious user may be able to execute arbitrary commands on a remote system. In some cases, the hacker may be able to gain root level access to the system, in which case the hacker might be able to cause copious damage to the system, or use the system as a jumping off point to target other systems on the network for intrusion and/or denial of service attacks. and many more related to cgi-bin directory. First I searched all the server for cgi-bin folder and it did not find any. Second I'm running my website on pure .NET and I don't use any scripts like php. Question is how can I remove this CGI thing from the IIS?

• Configuring and managing Windows web server

  - by Mike C.

  Hello, I run a few websites and I was thinking of paying for a dedicated Windows web server from GoDaddy instead of paying for each site's hosting individually. I know enough about IIS to configure the Host Header and stuff like that, but I'm a little fuzzy about the email portion of the hosting. I have a few questions: Do I need to install an SMTP server on the web server to allow for emails to be sent/received to a website email address? Or is there another approach that I'm unaware of? Are there tools that monitor the amount of bandwidth used by the server? GoDaddy charges for bandwidth and I want to make sure I don't go over. Am I opening a can of worms that I don't really want to open by going the dedicated server route? Things like server updates, security, etc? Thanks!

• A special user does not appear in Windows login screen

  - by shayan

  In the list of users (under Local Users and Groups in my Windows 7) I have an ASPNET user (its description says "Account used for running the ASP.NET worker process (aspnet_wp.exe)" and its full name is "ASP.NET Machine Account") The thing is this user does not appear in Windows login screen. What I have found: It is not a "Built-in security pricipal" user It belongs only to Users group I don't have HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\SpecialAccounts key in my registry In every sense I can see that it is a normal user yet it does not appear in login screen. Now the questions are: What does make it special? How can I create a user like this?

• How is the "change password at next logon" requirement supposed to work with RDP using Network Level Authentication?

  - by NReilingh

  We have a Windows server (2008 R2) with the "Remote Desktop Services" feature installed and no Active Directory domain. Remote desktop is set up to "Allow connections only from computers running Remote Desktop with Network Level Authentication (more secure)". This means that before the remote screen is displayed, the connection is authenticated in a "Windows Security: Enter your credentials" window. The only two role services installed on this server is the RD Session Host and Licensing. When the "User must change password at next logon" checkbox is selected in the properties for a local user on this server, the following displays on a client computer after attempting to connect using the credentials that were last valid: On some other servers using RDP for admin access (but without the Remote Desktop Services role installed), the behavior is different -- the session begins and the user is given a change password prompt on the remote screen. What do I need to do to replicate this behavior on the Remote Desktop Services server?

• software package disappeared in GPO after access rights change

  - by sirka

  Hi, in GPO, this item Computer > Software settings > Assigned applications > IE8_package was on Security tab set "Authenticated users" to "Deny". After that it disappeared from GPO, it is there, but nowhere shown. The intention was to disable installation of that package for now, yet having other packages in that GPO still installed. I know it was stupid decision now. Is there any way to display that package back? Please help.

• What does NT_STATUS_BAD_NETWORK_NAME mean in Samba?

  - by Neil

  I set up a share like this: [global] security = user map to guest = Bad Password usershare allow guests = yes [vms] comment = VirtualBox Virtual Machines path = /home/neil/VirtualBox/HardDisks guest ok = yes read only = yes And when I access the share as myself, and type in my password, it works fine: $ smbclient //neil-ubuntu/vms -U neil Enter neil's password: Domain=[SHUTTERSTOCK] OS=[Unix] Server=[Samba 3.4.0] smb: \> But when I access it as guest, it doesn't work: $ smbclient //neil-ubuntu/vms -U guest Enter guest's password: Domain=[SHUTTERSTOCK] OS=[Unix] Server=[Samba 3.4.0] tree connect failed: NT_STATUS_BAD_NETWORK_NAME Regardless of what password I type in. Does anyone know why? Also, why does smbclient print such useless error messages?

• Unable to authenticate Windows XP clients agains Snow Leopard Server PDC after 10.6.2 upgrade

  - by Roland

  I have setup a Snow Leopard Server 10.6.1 as a PDC without problems to authenticate Windows XP clients. Joining a Windows XP client to the SLS PDC Domain and log in from a Windows XP client to the SLS PDC Domain are working. After the update to Snow Leopard Server 10.6.2 the authentication is broken. opendirectory_smb_pwd_check_ntlmv1 gave -14090 [eDSAuthFailed] By changing the Windows XP "Network security: LAN Manager authentication level" policy to NTVLM2 responses only the authentication agains a SMB share is possible, but trying to join SLS PDC Domain is still not possible. opendirectory_smb_pwd_check_ntlmv2 gave -14090 [eDSAuthFailed] Any ideas? Is anyone else having similar authentication difficulties?

• Mimic the behavior of a machine added to a domain

  - by Ian

  Hello, For some reason, the IT department at our company does not want to add Windows 7 and Windows Vista machine to the domain controller. I hate to always provide my network credentials everytime I access a shared folder on a machine that is joined to the domain. I also hate to always provide my password when I launch outlook or Visual Studio (Team Explorer). Is there a way to mimic the behavior of a machine that is added to a domain without actually adding the machine in the domain? For shares, I can create a batch file that will NET USE the different fileservers we use here but that is a huge security risk as I will type my password as plaintext. Thanks!

• Flash Player in Windows 7 X64 problems

  - by Flupkear

  I'm having a lot of problems with flash player in my win 7 X64 laptop, in YouTube the videos are completely black, you can only hear the sound and in Vimeo the videos are played well in normal size but completely black in fullscreen. Also some days ago YouTube played normal size videos but with controls not visible. I'm sure that the problem isn't the browser since this happen in Chrome, Firefox and IE 8. My laptop is a Dell XPS L501X, the flash version is 10,2,152,26 and the OS is Windows 7 Home Premium with SP1. I'll appreciate any help.

• TP-Link TL-WA701N not working good as wireless extender

  - by djechelon

  I bought the device in subject to extend the range of my WPA2/PSK-protected wifi network powered by a TP-Link TL-WR340G device (AP+router). I configured it as follows: Operation mode: Universal Repeater MAC of AP: scanned my SSID and got it Channel width: 20MHz Security options: the same as the parent AP (WPA2/PSK with AES encryption) After configuration inSSIDer shows me two APs beaconing the same SSID at different SNRs (because I was with my laptop close to the extender). After a few hours my tablet, far from the parent AP, stopped working. I found that the scan reported two networks with the same SSID: one WPA-protected and one free at all. This happened very frequently. Rebooting the extender by unplugging it worked but this doesn't last long. Sometimes the extender stops transmitting at all, sometimes it beacons an open network to which nobody can connect (because there is no DHCP). What's wrong with my configuration?

• How to make MAMP PRO / XAMPP secure enough to serve as production webserver? Is it possible?

  - by Andrei

  Hi, my task is to setup a MAMP webserver for our website in the easiest way so it can be managed by my colleagues without experience in server administration. MAMP PRO is an excellent solution, but some guys don't suggest to use it for serving external requests. Could you explain why it is bad (in details if possible) and how to make it secure enough to be a full-scale and not-only-local webserver? Is there a better solution? Update There is a discussion on the MAMP website. XAMPP developers say that one can make their product secure: The default configuration is not good from a securtiy point of view and it's not secure enough for a production environment - please don't use XAMPP in such environment. Since LAMPP 0.9.5 you can make your XAMPP installation secure by calling »/opt/lampp/lampp security«. Could you comment it?

• Dynamic DNS registration for VPN clients

  - by Eric Falsken

  I've got a VPN server set up in my Active Directory on a remote network. (VPN Server is separate box from DNS/AD) When I dial into the network (client machine is not a member of the AD) the machine does not register its IP or Hostname in the DNS. I've played with all possible combinations of DHCP and RRAS-allocated IP pools, and none of them seem to cause my client to register. Is it because my client has to be a member of the domain? Are there some security settins I can tweak so that it can register its hostname/ip? I've looked in the event logs (System and Security) for the AD, DNS, DHCP, RRAS, and the client machine, and don't see anything relating to DNS Registration. Here's the IPConfig on the client machine (once connected): PPP adapter My VPN Name: Connection-specific DNS Suffix . : mydomain.local Description . . . . . . . . . . . : My VPN Name Physical Address. . . . . . . . . : DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes IPv4 Address. . . . . . . . . . . : 192.168.1.22(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.255 Default Gateway . . . . . . . . . : DNS Servers . . . . . . . . . . . : 192.168.1.52 <- DC1 192.168.1.53 <- DC2 NetBIOS over Tcpip. . . . . . . . : Enabled Edit: It looks like my clients are not recieving the DHCP Scoope Options. I found this great article in Microsoft's KB. So the problem here is that the VPN Server "pre-reserves" the DHCP addresses, but then you have to add the DHCP Relay Agent to relay the secondary request for scope options. My problem is that the DHCP Relay Agent isn't relaying to the local DHCP server (same box as the VPN/RRAS). I've configured the DHCP Relay Agent according to this KB, but it dosn't work for a local DHCP server. (I see the request count increasing, but no responses) I was able to get everything working by specifying the DNS server and domain name in the VPN connection properties on the client. But am still unable to assign it (or the default gateway) dynamically via DHCP. The client also has to be a member of the remote domain.

• How To Change What Version of PHP Apache2 Uses?

  - by nicorellius

  I just discovered that I am using the wrong version of PHP for a CRM application. Once I figured out how to make a simple phpinfo() script to tell me what Apache2 is using, I tried changing the php.ini such that my webserver would use the PHP I want. Well, this is my problem. Not sure how to do that. I compiled the version of PHP I want to /etc here: /etc/php-5.2.8/ Inside this, there was a php.ini-recommended file that I made some changes to and renamed to php.ini so PHP would use it. But when I opened my browser and cleared my history and went to the http://localhost<CRM dir>/install.php address, the wizard still says I'm not usign the correct version of PHP. Based on this post what do I have to do to change the version of PHP that shows up after I run my test.php script? In other words, phpinfo() says I'm running PHP 5.3.2, but I want to change it to my compiled 5.2.8 version located in /etc.

• IIS - Forwarding requests to a folder to another port

  - by user1231958

  Context I currently installed Glassfish 3 in a server that currently holds ASP and PHP inside Internet Information Server 7 so we can start moving to a new system architecture (the information system is being remade). Obviously, Glassfish uses another port and without too much configuration (all I had to do is to install it) it worked. If I write www.domain.com:8080, the person will be redirected to the Glassfish server. Issue Obviously I don't want the person to write the port! I also believe it might also hold some security issues. Requirement I need the server to take an address of the form www.domain.com/gf or new.domain.com or something alike, and when it receives such a request, "redirect" (masking the URL) the user to the Glassfish website (www.domain.com:8080). Thank you beforehand!

• Access internal IP using public IP

  - by willvv

  Hi, I have a DSL modem with a public IP address (201.206.x.x), and I have a web server in my internal network (192.168.0.50). I set up the modem to forward requests to port 80 to my web server, so, if I access 201.206.x.x from outside my network, it shows my web page, the same happens if I access 192.168.0.50 from a computer inside my network. Now, the problem is when I try to access 201.206.x.x from my internal network, the browser tries to connect to the DSL modem configuration, instead of redirecting my request to my Web server. Which settings do I have to change in the modem to set up this redirection? Thanks!

• Smart card / auditable access for rack KVM tray

  - by Mark Henderson

  Is there such a thing as a KVM Tray for a standard 19" rack whose use can be validated by a smartcard (or some other auditable authentication method)? It looks like we have a security requirement where just because users have a key to the rack doesn't mean they will be allowed to use the console inside the rack, and rather than just lock the console (and keep track of who has keys), we would prefer to be able to audit the actual user that was attached at the KVM. (It's worth mentioning that I'm aware of the Raritan devices, but they surely can't be the only ones) (If these things existed, I don't think half of the tratoirs that somehow manage to infiltrate CTU on the TV show 24 would ever get away with anything)
