• Why do I get "Permission denied (publickey)" when trying to SSH from local Ubuntu to a Amazon EC2 se

  - by Vorleak Chy

  I have an instance of an application running in the cloud on Amazon EC2 instance, and I need to connect it from my local Ubuntu. It works fine on one of local ubuntu and also laptop. I got message "Permission denied (publickey)" when trying to access SSH to EC2 on another local Ubuntu. It's so strange to me. I'm thinking some sort of problems with security settings on the Amazon EC2 which has limited IPs access to one instance or certificate may need to regenerate. Does anyone know a solution?

• Can you have a WMI query for GPO Filter based on user's OU?

  - by Jordan Weinstein

  I'm wondering if there is a way to have a WMI query check the OU of the user logging on. I'd like a GPO (linked to Citrix servers OU) to apply only to users if the user is in a certain OU - this is for Citrix so the overly obvious answer of - well just link it to the OU the user is in does not apply. This also cannot be done using security groups because a long time ago those started to get used as Distribution Groups also and now too many are widely inaccurate. Lastly I need to apply this to the entire GPO as there are more than just group policy preferences included so I can't use the item-level targeting feature either. But my OUs are accurate so I'd like to use those if I can. I'd like a WMI query filter to say, apply GPO if user is member of OU 'x' that doable?

• Run a command from Windows 7 Start Menu

  - by Abhijeet Patel

  I'm trying to run commands such as "cmd.exe", "appwiz.cpl" etc by typing it in the Search box of the Start Menu in Windows 7 (x86). I'm able to do this just fine in Vista. After typing in "cmd" I notice that I see a link to "Programs" in the start menu so it seems that "cmd" is being recognized but when I click on "Programs" link which is shown,I get the following message. "These files can't be opened. Your internet security settings prevented one or more files from being opened" P.S. - I'm not looking for enabling the "Run" command to show in the Start Menu Any help would be much appreciated

• EC2 server in VPC stops responding after joining domain

  - by Geoff

  We have a EC2 Windows Server set up and running in our VPC, connected to our network via a Juniper 5GT. This is working well, with the tunnel up and stable. If I then join the server to our local domain, it appears to work - I can then log on using domain credentials, and use domain accounts when applying security to folders etc. After I log out, if I give it around an hour, the box becomes unresponsive. I can't ping it, although a tracert goes all the way barring the last hop - so the tunnel is ok. I can't RDP into it. If I reboot it, then it works for a while before doing the same thing. Un-joining it from the domain fixes the problem, and it stays up and stable. The event logs don't show anything obvious, at least to me. Any ideas?

• Firewall GPO not applying despite being enumerated by gpresult

  - by jshin47

  I have a need to open up the admin$ share on all of my domain's client PC's and I am trying to do so using group policy. I defined computer policy for Windows Firewall with Advanced Security in a policy object linked to the appropriate container and added the appropriate rules. However, they are not being applied! I feel like I have tried all of the obvious steps: I've checked gpresult and the resulting set of policy is the way that I would expect it to look. I've gpupdate /force and gpupdate /sync on a few client computers, but no matter what I do they don't seem to respond to my changes. I know that other computer policies in the GPO are being applied so it is strange that these are not. I have also disabled exceptions on clients in the firewall GPO, but that doesn't seem to be applying either. Here is a screenshot of the firewall.cpl from a client: Basically, although other options in the same GPO ARE applied for computer policy, the firewall settings seem to be ignored.

• How anti-virus on the host machne affects performance of virtual machines?

  - by Ladislav Mrnka

  I'm diagnosing some issue with Oracle virtual box where virtual machine sometimes perform terribly slow (much slower then notebook with worse configuration): Notebook i7 (2 cores with HT = 4 logical CPUs), 4GB RAM, 5400 rpm disk, Win 7 64bit Virtual machine (Oracle Virtual Box) Host: i7 (4 cores with HT = 8 logical CPUs, 12 GB RAM, system runs from SSD, virtual machine from 7200 rpm disk, Win 7 64bit) Virtual machine: 4 cores assigned, 8 GB RAM assigned, Win 2008 R2 Enterprise (64 bit) Virtual machine uses bridge to separate network interface (machine has two) VPN for network communication No other virtual machine runs on the host Host has installed ESET Smart Security All SW is updated with last version. My question is if anti-virus on the host machine can somehow affect performance of the virtual machine and if so how can I turn it off without turning the anti-virus itself?

• Windows 7 Long Delay on Login or Unlock

  - by Adam Driscoll

  I have a clean install of Windows 7 x32 running on my HP DV6449us and am experiencing a really long delay (10+ seconds) when unlocking or logging into my computer. The same issue was happening with UAC but I was able to turn that off. I realize this is a security risk but couldn't take it any more. I've read about this being video driver related but have updated the drivers to the newest I could find for the GeForce Go 6150. Anyone else experiencing this? My desktop is very happy but he's sporting a Nvidia 260 GT. Is it just the lack of firepower?

• SSL 3.0 warning in Chrome on Ubuntu 10.04LTS

  - by Leopd

  I'm running Apache2 with SSL on Ubuntu 10.04LTS. Chrome gives me this annoying warning when I inspect the certificate: The connection had to be retried using SSL 3.0. This typically means that the server is using very old software and may have other security issues. The relevant part of the apache config looks like: SSLEngine on SSLCertificateFile /etc/ssl/... SSLCertificateKeyFile /etc/ssl/... SSLCACertificateFile /etc/ssl/... SSLProtocol -all +SSLv3 +TLSv1 The last line I added to try to address this problem, but it's not working. Any advice on properly enabling TLS?

• When the Windows Firewall Service is disabled I cannot remote desktop (RDP) to the machine

  - by Matt

  When the Windows Firewall Service is disabled I cannot remote desktop (RDP) to the machine. Has anyone seen this? This is on Win7 64 Enterprise on a domain. Is it some sort of domain policy perhaps? EDIT: Yes, when the firewall service is enabled, RDP works like a charm. I can also ping the system when the firewall service is on, but not when it is off. I am starting to suspect some sort of corporate imposed security policy, but GPedit hasn't really showed anything of significance.

• Creepy MySQL error during hard work

  - by Kiewic

  Hi, I have a MySQL database installed on a OpenSuse 11.1 server (it is a Bitnami image). The database works fine, it can stay many days without any error, but when MySQL receives a huge amount of transactions, it dies immediately. The next screen shows the error: Moreover, I don't know how to restart MySQL. I have tried this: /opt/bitnami/mysql/bin/mysqld start But it doesn't work, that gives me the next output: 110209 17:09:01 [ERROR] Fatal error: Please read "Security" section of the manual to find out how to run mysqld as root! 110209 17:09:01 [ERROR] Aborting 110209 17:09:01 [Note] /opt/bitnami/mysql/bin/mysqld.bin: Shutdown complete It doesn't matter which kind of statements are executing, if they are a huge amount, MySQL dies. The MySQL server version is 5.1.30 What can be causing these sudden failures?

• Remote Access Without Explicit Permission: Convenience or Liability?

  - by routeNpingme

  For outsourced professional IT remote support, one habit most new technicians get into is the "instead of getting the user to start up remote support each time, I'll go ahead and install LogMeIn / GoToMyPC / Remote Desktop / whatever so that if they call again, I can just jump on and help them". This of course opens up a potential liability because a client PC on a network that we don't own is being accessed without a user explicitly providing permission by clicking a "Yes, allow technician to control my PC" option. I realize the rules totally change when you're an IT admin over a network that you "own", but this is outsourced IT support. Just curious what others' policies are. Is this an acceptable practice for convenience and I'm turning into one of those "security is more important than anything" people, or is this really a liability?

• samba - join domain - automatically set workgroup

  - by ftiaronsem

  Hell alltogether Since I have to do this often, I want to automate the joining to a windows domain as much as possible. While joining a domain one has to specify realm = in the /etc/smb.conf, along with some other settings like security=ads. Among these settingst there is workgroup = My question is: Is it possible to fill this field automatically by samba, while joining a domain? Normally I would just have said never, but as I tried leaving this field blank while joining a domain, i got: Failed to join domain: Invalid configuration ("workgroup" set to '', should be 'BLABLA') and configuration modification was not requested This has made me wondering whether an automatic modification is possible and if so how? A search on the internet and the man page brought no results. It would be really great, if someone could answer that. Thanks in advance ftiaronsem

• How to set my Ubuntu account to super user at all times?

  - by iaddesign

  I have the latest Ubuntu installed and I'll be the only one using it off the network. My question is: how can I make myself super user at all times? Because when I try to delete a file it says I don't have privileges to do so. I know you are going to say it's a security risk but I'm off the network and want to learn all that I can. I don't want to delete the files through the terminal but want to do it through the user interface/explorer. I've installed LAMP and can't copy my site to the www directory. I've tried to remove the preinstalled index file and it won't let me.

• Issue with https:// url going to an unknown location

  - by Brandon

  We have a website (ASP.NET/Plesk 9.5.5) that can be accessed just fine through the regular URL (http://example.com). However when accessing the site through https://example.com the site displays the invalid security certificate warning, which is fine since we don't have an SSL certificate. If I add an exception, I'm sent to a completely separate site that is apparently hosting a malware script (I'm still on https://example.com though). Because of this Google has flagged the site as dangerous. I can't find anything in the Plesk panel that would help fix this, and as far as I can tell those files don't exist on our server. How do I tell where the https:// link is sending me? I'm not that familiar with DNS, but is that what is causing this behavior?

• Debian is equal to Ubuntu

  - by rkmax

  The title of the question is confusing, and does not explain my point well. I've always used Ubuntu server from version 10.04 and never had problem, now I have 4 machines with ubuntu 12.04.1 LTS installed on them and I found that under any circumstances where there is a high burden throws me a problem and machine crashes constantly. the most common is CPU#X stuck for Ns! Now I wonder if the administration of Debian is equal to that of ubuntu, regarding Servicos, packages, folders structure for example I would like to know if the services are installed in the same manner using invoke-rc.d, which handles additional security, including for not giving blind caning. I've been looking for a comparison chart but have not found anything yet, something between Debian 6.0.6 and Ubuntu 12.04 also the most common "hiccups" when you install the system

• Configuring sendmail to use one outbound MTA exclusively

  - by Charlie Martin

  I have a sendmail problem, and I'm anything but a sendmail guru -- I could use some help. My problem is that I have a system intended to be more or less an "appliance" -- it's not intended to have an admin. Because of this, it needs to be able to "call home" by sending email. As we have configured it, this works fine -- using sendmail, it finds the appropriate relay by looking up an MX record and everything works fine. Now, however, because of security concerns, we want to limit it to using exactly one relay, so for example relay.corp.example.com. Should the user configure it to use, say, fubar.example.com, the mail sending should fail or be deferred. I thought that by configuring sendmail with a /etc/mail/server.switch file containing hosts files without dns, I'd get that effect. This doesn't work -- instead, if it gets mail addressed to [email protected], it tries to talk directly to example.com, and ignores the configured server. Any ideas?

• After virus, Chrome & Internet Explorer won't connect to the internet, but Firefox works fine.

  - by Zack

  I cannot connect to the internet with Chrome or Internet Explorer. Firefox works fine. It seems it happens when I was infected by a "Trojan Horse Generic 17.BWIK", "Trojan Horse SHeur.UHL" and "Fake_Antispyware.FAH". I have removed the threats using AVG anti-virus security. I got Firefox working, but Chrome and IE still cannot connect. I do not want to loose Chrome History so re-setting would be my last option and uninstall and install will be out of the question. Is there a way around this? I am using XP Pro on a desktop and DSL connection.

• SSH reverse tunnel to monitor and manage remote devices

  - by acid_crucifix

  I have a set a distributed set of devices running Ubuntu 12.04 that I am distributing to clients. I would like to manage them remotely. They may not have fixed IPs and potentially might be behind firewalls. What I am planning to do is have the devices (permanently connected to the net) poll a request URL and based on the response open a reverse tunnel to my server, so that I can access them via that tunnel. Most of what I read about reverse tunnel over SSH is for single use cases and very little about heavy production usage. Is there some reason for this, security issues? or stability? Any help would be much obliged.

• What's the situation that requires stateful firewall?

  - by Eonil

  I just know there is two kind of firewalls. Stateless and stateful. It's hard to determine what kind of firewall I have to use. Currently I have to run firewall within same machine runs services, Basically I want stateless because of its less resource consumption. However if it is not sufficient for security, it's meaningless. I'll run HTTP, SSH, NFS (only over SSH), and some custom made server on several TCP/UDP ports. Should I use stateful firewall? (edit) Maybe the question can be assumed as 'Should I use stateful rules?'.

• How do I create certificates for both ends of an stunnel connection?

  - by unixman83

  Hi. I am using stunnel to authenticate RDP (Remote Desktop) and I need to verify that a client possesses the proper credentials. So people cannot brute force into the machine. I am also using a bad (outdated) version of RDP that has security vulnerabilities, so stunnel is a must. I will preshare the necessary .pem's between machines. What are the openssl commands I need to create the right .pem files on both the client and on the server? What files need to be shared?

• Dual HDD dual boot Win7/Win7 hibernate corrupts partitions?

  - by Ivan Zlatev

  I have two SSDs in my laptop. Both have 2 partitions each one with Windows 7 64bit and another one with OEM stuff on it (SYSTEM_DRV). I use the BIOS boot menu to boot between the drives. I have removed the drive letters so that no partitions of drive 1 are mapped in windows 2 on drive 2 and wise-versa. What I have observered however is that when I hibernate windows 1, boot windows 2 do some work and shutdown then resume windows 1 - the windows 2 partition will get corrupt quite often. Just happened actually - it is shown as "RAW" in the Disk manager instead of NTFS and windows will blue screen at boot. Alternatively I've seen cases where chkdsk will run and will wipe out all security descriptors making the partition completly unbootable. Why am I seeing these corruptions and what can I do to prevent them?

• LinkSys WRT54GL + AM200 in half-bridge mode - UK setup guide recommendations?

  - by Peter Mounce

  Crossposted from here I am basically looking for a good guide on how to set up my home network with this set of hardware. I need: Dynamic DNS Firewall + port-forwarding VPN Wake-on-LAN from outside firewall VOIP would be nice QoS would be nice (make torrents take lower priority to other services when those other services are happening) DHCP Wireless + WPA2 security Ability to play multiplayer computer games I am not a networking or computing neophyte, but the last time I messed with network gear was a few years ago, so am needing to dust off knowledge I kinda half have. I have read that I should be wanting to set up the AM200 in half-bridge mode, so that the WRT54GL gets the WAN IP - this sounds like a good idea, but I'd still like to be advised. I have read that the dd-wrt firmware will meet my needs (though I gather I'll need the vpn-specific build, which appears to preclude supporting VOIP), but I'm not wedded to using it. I live in the UK and my ISP supplies me with: a block of 8 static IPs, of which 5 are usable to me a PPPoA ADSL2+ connection

• Windows 7 wifi reports "no network access" and "no internet access" but connects in fedora

  - by rick2047

  I am running windows 7 home basic (64bit) on a Acer 5742G laptop with Atheos wifi adapter in it. Yesterday, I hiberneted my computer as I always do and up untill then the wifi was working fine. When I booted my computer up again today I started having a strange problem: It detects my wifi but after connecting to it, it keeps on oscillating between states of no network access and no internet access. I can't connect to anything (the internet or my router). I tried to reset my internet protocol stack using this fixit file. I also tried to uninstall and reinstall my network driver. Neither helped. I am using the same laptop's fedora installation right now and the wifi is working perfectly fine. Please help. Edit To add additional details, I have Microsoft Security essentials as my antivirus software and I haven't messed with the firewall or the router configurations.

• Client side certificates in client browsers with unix server for management

  - by user146253

  We are currently running Unix dedicated servers for everything (Web cluster, database, FTP, batch, ...) except for a Microsoft Active Directory Certificate Services. The sole purpose of this Windows box is to provide client side certificates to our clients browsers. All our clients are required to install a client side certificate on order for them to be able to access our website. Is there an alternative in the Unix space? The purpose is to make sure only the approved hardware of an approved client can access our website. I'm open for any solution that provides me with this level of security. We are however talking about thousands of certified computers just so you can factor that in in a proposed solution. Optionally we would also like to be able to revoke access. With Regards.
