  • Amazon AWS VPN how to open a port?

    - by Victor Piousbox
    I have a VPN with public and private subnets; I am considering only public subnet for now. The node 10.0.0.23, I can ssh into it. Let's say I want to connect to MySQL on the node using its private address: ubuntu@ip-10-0-0-23:/$ mysql -u root -h 10.0.0.23 ERROR 2003 (HY000): Can't connect to MySQL server on '10.0.0.23' (111) ubuntu@ip-10-0-0-23:/$ mysql -u root -h localhost Welcome to the MySQL monitor. Commands end with ; or \g. --- 8< --- snip --- 8< --- mysql> The port 3306 is not reachable if I use the private IP? My security group allows port 3306 inbound from 0.0.0.0/0 AND from 10.0.0.0/24. Outbound, allowed all. The generic setup done by Amazon through their wizard does not work... I add ACL that allows everything for everybody, still does not work. What am I missing?

  • Anti Virus Service does not run - Windows XP SP3 32bit Home

    - by Stefan Fassel
    I have a somewhat strange problem here. I am trying to run Anti Virus Software on my Windows XP Home 32bit System. After a serious crash I had to fall back to an outdated copy of my initial installation and had Windows install 5 years of updates. So far so good. After Intalling a new Anti Virus Software (Bitdefender 2012) everything seemed to be fine, initial scanning went fine and configuration was working. But after restarting the System the Virus Scanner was unable to start up again. Even the Configuration console of the AV Software did not start. I tried scanning the System for malware, but nothing was found. Then I tried a different AV Software (MS Security Essentials), but in the end it did fail to start too. I have tried to start the Service manually, but I seem to be missing the privilege to do so. I am logged in as a Non-"Administrator" User with Admin privileges (Not much choices there on a XP Home System). I cannot switch to Administrator account outside the protected mode. When running Windows in protected mode I am unable to start the AV Software because it does not run in protected mode. I am a bit at loss now...

  • How to configure a trusted connection between IIS 7 and SQL Server 2005?

    - by user1180652
    How do configure a trusted connection between IIS 7 and SQL Server 2005? My webapp was working fine with Windows Authentication enabled in IIS. Now, in order to solve a problem, we need to use a trusted connection. Unfortunately, enabling the trusted connection in the web.config broke the webapp. Oddly enough, when I run this application with trusted connection from my local dev machine (using the Cassini web server) IIS (Windows Server 2008) is running on one machine. The database (SQL Server 2005 but could migrate to 2008) is running on another machine. We are on a Windows domain running AD. All traffic is within our own firewall - no public access. Beyond that, I can't provide much info but I can find it. We're very "compartmentalized" (we have server people, security people, oracle people, SQL Server people, etc.) Thanks! Update 02/14/2012 0902: The webapp is now functional (app no longer broken) but the main issue is still unresolved. Now I have the app's application pool running as a domain account with permissions on the SQL Server box and IIS box. We were using this account to run the application but, and here's the problem, we need to log the real user name that made a change. When using the service account, the name of that service account appeared in the audit tables, making the auditing quite useless. So, not I'm at least running again. The connection string in the web.config is using "Trusted_Connection=True", the appPool is using a domain account with access to both boxes, BUT when I make a change (logged in as me) the name of the service account (appPool identity) is still logged in the audit tables. I also manually granted full permissions to the service account on the webapp folder. What do I need to do in order to log my name, not the service account, in the audit tables? Everything I'm reading says I need to establish a trusted connection between the two servers.

  • Creating an ec2 image on amazon fails at mkfs.ext3

    - by Dave Orr
    I'm trying to create an image of my ec2 instance in Amazon's cloud. It's been a bit of an adventure so far. I did manage to install Amazon's ec2-api-tools, which was harder than it seemed like it should have been. Then I ran: ec2-bundle-vol -d /mnt -k pk-{key}.pem -c cert-{cert}.pem -u {uid} -s 1536 Which returned: Copying / into the image file /mnt/image... Excluding: /sys/kernel/debug /sys/kernel/security /sys /proc /dev/pts /dev /dev /media /mnt /proc /sys /etc/udev/rules.d/70-persistent-net.rules /etc/udev/rules.d/z25_persistent-net.rules /mnt/image /mnt/img-mnt 1+0 records in 1+0 records out 1048576 bytes (1.0 MB) copied, 0.00677357 s, 155 MB/s mkfs.ext3: option requires an argument -- 'L' Usage: mkfs.ext3 [-c|-l filename] [-b block-size] [-f fragment-size] [-i bytes-per-inode] [-I inode-size] [-J journal-options] [-G meta group size] [-N number-of-inodes] [-m reserved-blocks-percentage] [-o creator-os] [-g blocks-per-group] [-L volume-label] [-M last-mounted-directory] [-O feature[,...]] [-r fs-revision] [-E extended-option[,...]] [-T fs-type] [-U UUID] [-jnqvFKSV] device [blocks-count] ERROR: execution failed: "mkfs.ext3 -F /mnt/image -U 1c001580-9118-4a50-9a25-dcf02be6d25f -L " So mkfs.ext3 wants -L, which is a volume name. But ec2-bundle-vol doesn't seem to take in a volume name as an argument, and the docs (http://docs.amazonwebservices.com/AmazonEC2/gsg/2006-06-26/creating-an-image.html) don't seem to think one should be needed. Certainly their sample command: # ec2-bundle-vol -d /mnt -k ~root/pk-HKZYKTAIG2ECMXYIBH3HXV4ZBZQ55CLO.pem -u 495219933132 -s 1536 doesn't specify anything. So... any help? What am I missing?

  • Windows 7 mapped drive kicking off OS X users

    - by Collin White
    I've mapped a network drive on my Windows 7 PC at my office. The windows machine has a few TB of storage that is being accessed by my development team (all running mac os 10.7). The share seems to work fine for a little while but will timeout and kick the mac users off and sometimes disallows a connection on the next attempt. Restarting the windows machine fixes the problem. I've tried this tutorial as well as setting the maximum session length in the Local Security Policy section to 99999 (I discovered 0 did not mean unlimited, only a 'reasonable ammount of time') anyway, the setting is now for ~208 days which is sufficient (see attached). I'm having trouble debugging this in general so if anyone has some pointers I'm all ears. This is a intermittent issue which in my opinion are the hardest kinds to debug. If anyone knows of how I might monitor connections from the PC that would also be pretty cool. Previously the files were hosted on a mac mini and everything was working just fine (the mini just didn't have the ability for the storage capacity we needed) so I believe it is some windows setting that is kicking users off. Anyway, thanks for reading.

  • Simple Linux program that takes any HTTP/HTTPS request and returns a single page?

    - by ultrasawblade
    I have a Linux box operating as router. There's a NIC that's connected to the internet (WAN), a NIC connected to an 8-port GbE switch (LAN), and a NIC connected to a Linksys wireless N-router (WLAN). Routing between everything is working perfectly. I have security completely disabled on the wireless router, but the WLAN NIC is firewalled such that it will only accept DNS queries and PPTP VPN connections. Currently HTTP/HTTPS traffic and everything else is blocked. I would like to run something that listens on port 80/443 of the WLAN NIC, and, for non VPN'ed connections, given any HTTP/HTTPS request it will return a single webpage saying "Unauthenticated" and explain how to sign into the VPN. A transparent proxy seems to be what I need, but my searches all seem to direct me to Squid, which is already running on my server and seems overkill for this simple task. Is there a simpler, lightweight program out there that does just this or should I just suck it up and run two instances of Squid (or figure out how to configure it)? Or, is this entire VPN thing I'm doing complete nonsense and I should just enable encryption on the wireless router?

  • Windows Server 2008 R2 - VPN Folder Sharing Permissions

    - by daveywc
    I have setup VPN access to my Windows Server 2008 R2 server using RRAS. Clients can connect, run applications, view shares etc. My problem is that one of the applications that they use relies on some network shares. The application is not able to access the shares unless the user first goes into Windows Explorer and accesses the share, providing their user name and password (the same one that they use to connect via the VPN). Previously on a different Windows Server 2008 (not R2) this was not necessary i.e. the application and user could access the share without providing another user name and password. I have tried giving the Everyone group full control over the shared folder - both on the Security tab and in the Permissions area under Advanced Sharing on the Sharing tab. This still did not resolve the issue. (I don't really want to give Everyone access anyway - I was hoping that granting access to a group that the VPN users had membership of would be enough). I have also turned off password protected sharing in the Advanced Sharing Settings area of the Network and Sharing Center (under both Home or Work and Public). So my question is what is preventing my VPN users from having access to these folders without having to re-supply the same login and password that they use to access the VPN? And what is the best practice in this type of scenario?

  • IP Blacklists and suspicious inbound and outbound traffic

    - by Pantelis Sopasakis
    I administer a web server and recently we had our IP banned (!) from our host after they received a notification e-mail for abuse. In particular our server is allegedly involved in spam attacks over HTTP. The content of the abuse report email we received was not much informative - for example the IP addresses our server is supposed to have attacked against are not included - so I started a wireshark session checking for suspicious traffic over TCP/HTTP while trying to locate possible security holes on the system. (Let me note that the machine runs a Debian OS). Here is an example of such a request... Source: 89.74.188.233 Destination: 12.34.56.78 // my ip Protocol: HTTP Info: GET 'http://www.media.apniworld.com/image.php?type=hv' HTTP/1.0 I manually blacklisted this host (as well as some other ones) blocking them with iptables, but I can't keep on doing manually all day long... I'm looking for an automated way to block such IPs based on: Statistical analysis, pattern recognition or other AI-based analysis (Though, I'm reluctant to trust such a solution, if exists) Public blacklists Using DNSBL I actually found out that 89.74.188.233 is blacklisted. However other IPs which are strongly suspicious like 93.199.112.126 (i.e. http://www.pornstarnetwork.com/account/signin), unfortunately were not blacklisted! What I would like to do is to automatically connect my firewall with DNSBL (or some other blacklist database) and block all traffic towards blacklisted IPs or somehow have my local blacklist automatically updated.

  • Setting Windows 7's Recycle Bin to automatically have a default disk space allocation for deleted files from newly mounted drives

    - by galacticninja
    How do I set Windows 7's Recycle Bin to automatically have a default disk space allocation for deleted files from external hard drives and TrueCrypt-mounted volumes? I remember in Windows XP, I can set a percentage of total disk space that will automatically be used as storage capacity for deleted files by the Recycle Bin, and this will be applied to all external HDs or TC-mounted volumes. Windows 7 defaults to the 'Don't move files to the Recycle Bin. Remove files immediately when deleted' setting for newly mounted external HDs and TC mounted volumes. Since I am expecting deleted files to go to the Recycle Bin, sometimes this causes an 'Oops' when I delete files in external hard drives or TC mounted volumes, as Windows does not move deleted files to the Recycle Bin, but just deletes the files permanently. I have to remember to manually set a custom Recycle Bin storage space for each new drive that is mounted by Windows to avoid this issue. I only use and mount TrueCrypt file containers, not drives. I also don't mount TrueCrypt file containers as removable drives. ('Mount volume as removable medium' is unchecked in Mount Options.) In my $Recycle.Bin > Properties > Security settings, 'System' and 'Administrators' are already set to 'Full Control', while 'Users' only have 'Special Permissions' checked in gray. There are no other groups. I haven't changed or edited anything in these settings. I am using Windows 7 Ultimate.

  • cannot reach munin port on other AWS instance

    - by Amedee Van Gasse
    2 AWS instances, in the same region but different availability zones, one is in regular EC2 and the other is in VPC, both have an Elastic IP, both are 64bit Amazon Linux AMI 2014.03.1. Both are running munin-node. The instance in the VPC is running munin-cron. I have added incoming TCP and UDP port 4949 to the security groups of both instances. On the munin node, I added an allow-line with the IP address (regular expression) of the munin server to /etc/munin/munin-node.conf. I bind munin-node to any interface using host *. Then I did sudo service munin-node restart. Then I ran netstat. $ sudo netstat -at | grep munin tcp 0 0 *:munin *:* LISTEN So the port is open there. On the munin server AND on the munin node: $ nmap AMAZON-IP -p 80,4949 | grep tcp 80/tcp open http 4949/tcp closed munin On the munin node: $ nmap localhost -p 80,4949 | grep tcp 80/tcp open http 4949/tcp open munin So from the outside, the http port is open (Apache is running) but the munin port is closed. The node can't even reach the munin port on it's own public IP address, but it can on localhost. I added port 80 as a sanity check, to be sure that there is network connectivity at all. So what am I overlooking here?

  • Running a service with a user from a different domain not working

    - by EWood
    I've been stuck on this for a while, not sure what permission I'm missing. I've got domain A and domain B, A trusts B, but B does not trust A. I'm trying to run a service in domain A with a user account from domain B and I keep getting Access is Denied. I'm using the FQDN after the username and the password is correct. The user account from domain B is a local administrator on the domain A server, the user account has the logon locally, and as a service permissions. Must. Get. This. Working. Update: I found something interesting in the logs I must have missed. This ought to get me pointed in the right direction. Event ID: 40961 - LsaSrv : The Security System could not establish a secured connection with the server ldap/{server fqdn/fqdn@fqdn} No authentication protocol was available. I've found a few fixes for 40961 but nothing has worked so far. I've verified reverse lookup zones. nslookup resolves the correct dc properly. still workin' at it. Upadte: In response to Evan; I ran " runas /env /user:ftp_user@fqdn "notepad" " then entered the users password and notepad came up. It seems to work successfully. This issue is now resolved. The problem is visible in the screenshot. Windows tries to use the UPN for the user account if you dig your user out of AD with the Browse button. This fails every time even with the right user and password. Simply using the SAM format (Domain\User) works. So simple, yet so annoying. Can't believe I missed this. Thanks to everyone who helped.

  • Windows : Map-a-network-drive to a remote Shared-Folder (on QNAP NAS) using OpenVPN

    - by spelltox
    Provided my lack of networking knowledge, I've been struggling with this issue for quite a few days now : I have a QNAP-TS212 NAS on which i've created a shared-folder (mostly excel files). All the computers in the local network (windows) are able to access it without any problem. Now, i want to access that shared-folder remotely (windows client), so : I enabled OpenVPN (and PPTP) in QNAP admin. Installed OpenVPN on the remote client. Applied the configuration file that the QNAP generated - Configuration (openvpn.ovpn) : client dev tun script-security 3 proto udp remote ***MY_WAN_IP*** 1194 resolv-retry infinite nobind ca ca.crt auth-user-pass reneg-sec 0 cipher AES-128-CBC comp-lzo OpenVPN connect successfully from the remote client. Now, here's my problem : I can ping the NAS (got IP 10.8.0.1) from the remote client, But when i try to map-a-network-drive, i don't see the shared folder or the NAS or any of the other computers in the network... I checked - all computers are in "WORKGROUP" workgroup. I'm probably missing some basic knowledge, So - any help would be greatly appreciated ! Many thanks.

  • How do I secure Sql Server 2008 R2

    - by Mark Tait
    I have both a dedicated and a VPS (from Fasthosts) virtual server - the web sites/applications I run on these, access Sql Server stored on the same web server. Until now, I have logged onto Sql Server on both the deidicated and VPS server, from Sql Server Management Studio - until I noticed in my server application logs, multiple attempts to logon to Sql Server using the 'sa' username, but failed password. So someone/bot is trying hard (repeatedly every couple of hours, for approx 20 attempts during each instance) to log on... so obviously I have to lock down access to Sql Sever remotely. What I have done is gone into Configuration Manager, and in Sql Server Network Configuration - Protocols for Sql2008 and also in Sql Native Client 10.0 Configuration - Client Protocols - I have diabled Named Pipes, TCP/IP (and VIA by default). I have left Shared Memory enabled. I also disabled in Sql Server Services, the Sql Server Browser. Now the only way I can manage the databases on these servers, is by logging on to them via Remote Desktop. Can anyone confirm if this is the correct way of stopping anyone maliciously logging on to Sql Server? (I'm not a DBA or security expert - and there are hundreds of articles advising all different ways - but I was hoping for the experts here to confirm, or otherwise, if what I've done is correct) Thank you, Mark

  • Virtual Machine Network Architecture, Isolating Public and Private Networks

    - by Mark
    I'm looking for some insight into best practices for network traffic isolation within a virtual environment, specifically under VMWARE ESXi. Currently I have (in testing) 1 hardware server running ESXi but i expect to expand this to multiple pieces of hardware. The current setup is as follows: 1 pfsense VM, this VM accepts all outside (WAN/internet) traffic and performs firewall/port forwarding/NAT functionality. I have multiple public IP addresses sent to the this VM that are used for access to individual servers (via per incoming IP port forwarding rules). This VM is attached to the private (virtual) network that all other VMs are on. It also manages a VPN link into the private network with some access restrictions. This isn't the perimeter firewall but rather the firewall for this virtual pool only. I have 3 VMs that communicate with each other, as well as have some public access requirements: 1 LAMP server running an eCommerce site, public internet accessible 1 accounting server, access via windows server 2008 RDS services for remote access by users 1 inventory/warehouse management server, VPN to client terminals in warehouses These servers constantly talk with each other for data synchronization. Currently all the servers are on the same subnet/virtual network and connected to the internet through the pfsense VM. The pfsense firewall uses port forwarding and NAT to allow outside access to the servers for services and for server access to the internet. My main question is this: Is there a security benefit to adding a second virtual network adapter to each server and controlling traffic such that all server to server communication is on one separate virtual network, while any access to the outside world is routed through the other network adapter, through the firewall, and on the the internet. This is the type of architecture i would use if these were all physical servers, but i'm unsure if the networks being virtual changes the way i should approach locking down this system. Thank you for any thoughts or direction to any appropriate literature.

  • Making it Easier for Older Users to Login to Multiple Accounts

    - by Mike Hagstrom
    I currently do consulting for a small business that has multiple applications that they need to login too. I'm trying to get them to start using Basecamp and Zendesk to make all of our lives easier when it comes to collaboration on big projects and quick helpdesk ticket items. However, I have recently been informed that it is difficult for them to remember all of these websites etc... to login too. However the login information is the same. Right now they have to login to: Windows Login Gmail I want them additionally to login to Basecamp Zendesk This is just a generation or two gap between myself and them, so I'm wondering what others do to solve these problems. Is there some way we could configure USB thumbdrives that somehow have Lastpass or something on that when plugged into the computer automatically log them into their Windows account, then when they were to say visit the Basecamp account would automatically log them into that? I think the security risk (of a list thumbdrive) is well worth the ability to use these extra applications. Unless anyone else has any other ways for making it easier for users to login to multiple sites.

  • Being a more attractive job candidate - Certs XOR Degree

    - by Zephyr Pellerin
    I'm currently working in an IT position, where I do helpdesk stuff, and predominantly security related issues/consulting (In the loosest sense of the term) In-House and for Service-Contract clients (as the only/acting CCSP [I guess I should say only person with Cisco experience] in my organization). I've professionally written Kernel Mode drivers for a gaming company. Among other things that I'm proud to put on a resume. I think of myself as very reasonably qualified as a System Administrator, With excellent Cisco experience, among other things I think would make a good addition to almost any IT staff in need of a new employee. However, Something has always tripped me up - Human Resources. Let me explain, I decided to skip the university route - I'm immensely glad that I did, The computer science graduates that I've met and work with rarely know much of anything about Computers (Until they gain some 'real' experience), Even when asked about Theoretical Computing fundamentals they can rattle something off about Turing Completeness but rarely do they understand the mathematical underpinnings. In short, I think instead of going to college, I'd rather pick up some real world experience. However, Apparently, Employers rarely think the same way. A quick perusal of jobs through the standard job search engine yields nothing short of a conspiracy to exclude anyone without 'A Bachelors Degree in Computer Science or Equivalent'. Interviews I've had in the past have almost always been entangled with - 1. My Age (Which I can't really change) and 2. Lack of Degree. Employers frequently disregard the CCNA/CCSP, The experience I've gained through internships, My extensive experience in x86 assembly and C, among so many other things I like to think are valuable to employers - In lieu of the fact that I don't have a piece of paper. So, AS AN EMPLOYER - Is it even worth working on my CCIE? Or should I pad my resume with certifications that are easier to acquire (Like CISSP, MSCE, Network+, etc.). Or should I ditch the whole idea and head back to get a Mathematics or CS degree?

  • scalable yet doable small-medium office network

    Hello, I'm studying up with both Microsoft and Cisco literature and I must say, my head is starting to get clustered up (pun intended). I've made a quick network diagram of a theoretical company... Company1 owns Company 2 and Company 3, which are all under separate rooms and networks, but must be able to share a few resources such as files or printers. Given the amount of info out there and best practices, I thought about posting here to get suggestions and see what would the pro's do. I can read and read all day and implement on my own, but if I dont get some outside input, how will I know if I'm doing something wrong, right? anyway, please take a look and see if this is an over-complicated network or a lackluster design for a small-medium company of about 35 people and lets say they will be double that number by end of the year... :) Using win2k3, esxi, windows xp.

  • How do I set up a Windows NFS share so that I can view it's contents on Linux?

    - by hewhocutsdown
    My NFS server is a Windows XP SP3 box with the Microsoft Windows Services for Unix installed. I have a share configured under C:\NFS with the share name NFS and ANSI encoding. Anonymous access is enabled, with the anon UID/GID set to 0/0. Additionally, I've set ALL MACHINES to Read-Write, and checked the checkbox to Allow root access. My first NFS client is a Ubuntu 10.04 box, with nfs-common installed. Running sudo mount -t nfs 1.1.1.1:/NFS /home/user/NFS succeeds, but when I attempt to view the folder (even as root), it tells me that I do not have the permissions necessary to view the contents of the folder. My second NFS client is an IBM iSeries box running OS/400 V5R3. I used the mount command below: MOUNT TYPE(*NFS) MFS('1.1.1.1:/NFS') MNTOVRDIR('/PARENT/NFS') OPTIONS('rw,nosuid,retry=5,rsize=8096,wsize=8096,timeo=20,retrans=2,acregmin=30,acregmax=60,acdirmin=30,acdirmax=60,soft') CODEPAGE(*BINARY *ASCII) which also mounts successfully. Attempting to WRKLNK '/PARENT/NFS' and use Option 5 to enter the directory yields a Not authorized to object error - even though I am a security officer with the *ALLOBJ special authority. My gut says that it's a problem with the Windows share, but I don't know what it could be. Do you have any suggestions?

I've tried openssl, but if you examine the output: $ echo -n | openssl s_client -connect www.google.com:443 CONNECTED(00000003) depth=1 /C=ZA/O=Thawte Consulting (Pty) Ltd./CN=Thawte SGC CA verify error:num=20:unable to get local issuer certificate verify return:0 --- Certificate chain 0 s:/C=US/ST=California/L=Mountain View/O=Google Inc/CN=www.google.com i:/C=ZA/O=Thawte Consulting (Pty) Ltd./CN=Thawte SGC CA 1 s:/C=ZA/O=Thawte Consulting (Pty) Ltd./CN=Thawte SGC CA i:/C=US/O=VeriSign, Inc./OU=Class 3 Public Primary Certification Authority --- Server certificate -----BEGIN CERTIFICATE----- MIIDITCCAoqgAwIBAgIQL9+89q6RUm0PmqPfQDQ+mjANBgkqhkiG9w0BAQUFADBM MQswCQYDVQQGEwJaQTElMCMGA1UEChMcVGhhd3RlIENvbnN1bHRpbmcgKFB0eSkg THRkLjEWMBQGA1UEAxMNVGhhd3RlIFNHQyBDQTAeFw0wOTEyMTgwMDAwMDBaFw0x MTEyMTgyMzU5NTlaMGgxCzAJBgNVBAYTAlVTMRMwEQYDVQQIEwpDYWxpZm9ybmlh MRYwFAYDVQQHFA1Nb3VudGFpbiBWaWV3MRMwEQYDVQQKFApHb29nbGUgSW5jMRcw FQYDVQQDFA53d3cuZ29vZ2xlLmNvbTCBnzANBgkqhkiG9w0BAQEFAAOBjQAwgYkC gYEA6PmGD5D6htffvXImttdEAoN4c9kCKO+IRTn7EOh8rqk41XXGOOsKFQebg+jN gtXj9xVoRaELGYW84u+E593y17iYwqG7tcFR39SDAqc9BkJb4SLD3muFXxzW2k6L 05vuuWciKh0R73mkszeK9P4Y/bz5RiNQl/Os/CRGK1w7t0UCAwEAAaOB5zCB5DAM BgNVHRMBAf8EAjAAMDYGA1UdHwQvMC0wK6ApoCeGJWh0dHA6Ly9jcmwudGhhd3Rl LmNvbS9UaGF3dGVTR0NDQS5jcmwwKAYDVR0lBCEwHwYIKwYBBQUHAwEGCCsGAQUF BwMCBglghkgBhvhCBAEwcgYIKwYBBQUHAQEEZjBkMCIGCCsGAQUFBzABhhZodHRw Oi8vb2NzcC50aGF3dGUuY29tMD4GCCsGAQUFBzAChjJodHRwOi8vd3d3LnRoYXd0 ZS5jb20vcmVwb3NpdG9yeS9UaGF3dGVfU0dDX0NBLmNydDANBgkqhkiG9w0BAQUF AAOBgQCfQ89bxFApsb/isJr/aiEdLRLDLE5a+RLizrmCUi3nHX4adpaQedEkUjh5 u2ONgJd8IyAPkU0Wueru9G2Jysa9zCRo1kNbzipYvzwY4OA8Ys+WAi0oR1A04Se6 z5nRUP8pJcA2NhUzUnC+MY+f6H/nEQyNv4SgQhqAibAxWEEHXw== -----END CERTIFICATE----- subject=/C=US/ST=California/L=Mountain View/O=Google Inc/CN=www.google.com issuer=/C=ZA/O=Thawte Consulting (Pty) Ltd./CN=Thawte SGC CA --- No client certificate CA names sent --- SSL handshake has read 1777 bytes and written 316 bytes --- New, TLSv1/SSLv3, Cipher is AES256-SHA Server public key is 1024 bit Compression: NONE Expansion: NONE SSL-Session: Protocol : TLSv1 Cipher : AES256-SHA Session-ID: 748E2B5FEFF9EA065DA2F04A06FBF456502F3E64DF1B4FF054F54817C473270C Session-ID-ctx: Master-Key: C4284AE7D76421F782A822B3780FA9677A726A25E1258160CA30D346D65C5F4049DA3D10A41F3FA4816DD9606197FAE5 Key-Arg : None Start Time: 1266259321 Timeout : 300 (sec) Verify return code: 20 (unable to get local issuer certificate) --- it just shows that the cipher suite is something with AES256-SHA. I know I could grep through the hex dump of the conversation, but I was hoping for something a little more elegant. I would prefer Linux tools, but Windows (or other) would be fine. This question is motivated by the security testing I do for PCI and general penetration testing. Update: GregS points out below that the SSL server picks from the cipher suites of the client. So it seems I would need to test all cipher suites one at a time. I think I can hack something together, but is there a tool that does particularly this?

  • What's the issue with this Samba setup?

    - by Dan Nestor
    I asked this on superuser, but I realized that may be the wrong place. I am duplicating the question here, I hope this is allowed. I am trying to share a directory through samba. In smb.conf I have the following: [global] workgroup = WORKGROUP security = user passdb backend = tdbsam netbios name = <hostname> [share_name] path = </path/to/share> writable = yes valid users = <username> <username>, the user in question, is the owner of directory /path/to/share. Permissions on the directory are 755. If I try to connect from another computer, the connection attempt is unsuccessful (I assume it's an authentication error, because it re-prompts me for the password). The client requires a domain name for authentication, I tried both WORKGROUP and the hostname/netbios name of the samba server. Samba logs on the server have no mention of the failed connection attempt. Firewall on the server is down. What am I doing wrong? Update: have since run smbpasswd -a <username> and now I am getting a clear error message, "not enough permissions to view contents of share".

  • NTFS permissions weird inheriance (second take!)

    - by Wil
    A complete re write of my previous question, in a different context. Basically, the issue is that when I create a new user within a new group, the new user has various permissions over various folders. I have deleted the group "users" from this user object, and it is simply a member of the group "test". I have created a folder called c:\foo, when I go to effective permissions under the security tab, I can see that the user "lockdown" has various permissions. As far as I can see, there is nothing that should allow lockdown access. The moment I remove users from this list, it behaves as I would expect, which makes me believe that for some strange reason, the users group behaves like the everyone group and is controlled by the system. That being said, I cannot understand this as under the list, it is not there - and further to this, with the same permissions as the first picture, guest does not have access. This has stumped me and any help is appreciated! (Tested in Windows 2003 and 2008) edit - Should also say that if I go to Effective Permission for the group the user is in, there are no boxes checked, so it is somehow just the user that is getting the permissions from somewhere.

  • MacBook Pro and Backtrack 5R1 Configuration

    - by user119346
    I have a Macbook pro Quad core (2.2/8gb ram/750gb hdd). I have went through tons of forums on the Internet, but none of them seemed to be updated for the current Backtrack 5R1, or the question of getting it to correctly work on the MBP. Can anyone help? I don’t have a USB Dongle, and I want to be able to use the internal airport extreme wireless of the MBP to use BT 5R1. I have downloaded Backtrack 5R1 onto VMWare Fusion, and got it up and running, but to no avail. It keeps recognizing my card as a Ethernet connection. Kismac wont recognize the card either. So what I am asking for is this: The proper “download method.” for Backtrack 5R1 to my MacBook Pro. (YES I AM WILLING TO RE-DOWNLOAD BT 5R1). The Complete process from start to finish, UP TO DATE, from someone who has done this using an MBP Running Lion OSX. The proper tweaks, settings, or commands to get my airport extreme wireless card to work (it is BROADCOM 4331 I think). The wireless connection I need to use the tools on both Backtrack 5R1 and Kismac. I mainly need to test WEP cracking on my network for security. The difference between running BT 5R1 on VMWARE Fusion and running from downloading it directly to the MBP, if there is, How to download it directly to the MBP?

  • Nginx + PHP-FPM Too Many Resources

    - by user3393046
    My Server has the following Specs CPU: 6 Cores Intel(R) Xeon(R) CPU E5-2650 v2 @ 2.60GHz RAM: 32 GB I have a problem with nginx+php-fpm. They are taking too many resources for an unknown reason. Even if i restart the nginx + php-fpm the start up processes will use many resources. My nginx Config is the following: user nginx; worker_processes auto; error_log /var/log/nginx/error.log warn; pid /var/run/nginx.pid; worker_rlimit_nofile 300000; events { worker_connections 6000; use epoll; } http { include /etc/nginx/mime.types; default_type application/octet-stream; log_format main '$remote_addr - $remote_user [$time_local] "$request" ' '$status $body_bytes_sent "$http_referer" ' '"$http_user_agent" "$http_x_forwarded_for"'; access_log /var/log/nginx/access.log main; sendfile on; #tcp_nopush on; keepalive_timeout 65; #gzip on; include /etc/nginx/conf.d/*.conf; } My php-fpm pool config is the following [www] user = nginx group = nginx listen = /var/run/php5-fpm.sock listen.owner = nginx listen.group = nginx listen.allowed_clients = 127.0.0.1 pm = ondemand pm.max_children = 1500; pm.process_idle_timeout = 5; chdir = / security.limit_extensions = .php I'm using on pm.ondemand since my website has to support many concurrent connections at the same time and i was unable to to it with dynamic/static. I guess this isnt the problem because as i said earlier when i restart nginx+php-fpm at the same time, they are taking too much resources without any request. Here is the screenshot with the CPU Usage http://s28.postimg.org/v54q25zod/Untitled.png

  • AD domain on web servers behind NAT - DNS issues?

    - by Ant
    I'm trying to setup an AD domain to manage the security between two Windows Server 2008 webservers that will sooner or later use NLB to balance website requests. I've hit a problem which I think is a simple solution and is down to DNS. My website domain is mydomain.com. The two servers are running behind a NAT firewall on the 10.0.0.0 IP range. I've setup the AD domain to be called ad.mydomain.com (as recommended by MS and a few other answers to questions on here). The second web server however doesn't want to join the domain, and gives an error pinning the problem on DNS - "ensure that the domain name is typed correctly" even though it queries the SRV record successfully and gets the correct DC back - dc.ad.mydomain.com. Doing a dcdiag /test:dns on the DC gives the Delegation error 'DNS Server dc.mydomain.com Missing glue A record'. I have a feeling I need to add something to the public DNS so that it in some way knows about ad.mydomain.com. Can anyone suggest whether I'm on the right track in adding something to the public DNS? Or whether it's something else? Many thanks
