  • Windows Server 2012 - SSL Cypher Suite Order Not Long Enough

    - by Sam
    I want to re-order the cypher suites on our new Windows Server 2012 box to help mitigate the BEAST vulnerability for our clients. I went to Local Group Policy => Computer Configuration => Administrative Templates => Network => SSL Configuration Settings, opened SSL Cypher Suite Order, enabled it, and copied the values from the SSL Cypher Suites textbox. I pasted them into notepad, re-ordered them, then copied+pasted them back into the SSL Cypher Suites textbox. However, the box isn't long enough to hold them all, despite the fact that the length didn't change. I would have to drop the last 3 cyphers (SSL_CK_DES_192_EDE3_CBC_WITH_MD5,TLS_RSA_WITH_NULL_SHA256,TLS_RSA_WITH_NULL_SHA) in order for it to fit. Should I just drop them? Other ideas?

  • FTP transfer timeouts while uploading small files

    - by Hamed Momeni
    I have this problem that when I need to transfer some files (mostly small files < 100KB) the connections time out. Well actually it uploads one file and it fails on the next until my client reconnects to the server and the same thing happens over and over again. I googled the problem and some said that switching from passive mode to active mode could solve the it but it didn't work for me. Even continuously pinging the server to keep the connection alive was to no avail. P.S. I have root access to the server. Update: I'm running ProFTPD on a CentOS vps. I tried a few clients (FireFTP, FileZilla) all having the same problem.

  • PCI scan findings and problems with week ciphers on ports 993,443,995,465

    - by user64991
    From PCI scan results: Synops is : The remote service encrypts traffic using a protocol with known weaknesses . Description : The remote service accepts connections encrypted using SSL 2.0, which reportedly suffers from several cryptographic flaws and has been deprecated for several years. An attacker may be able to exploit these issues to conduct man-in-the-middle attacks or decrypt communications between the affected service and clients . See also : http://www.schneier.com/paper-ssl.pdf Solution: Consult the application's documentation to disable SSL 2.0 and use SSL 3.0 or TLS 1.0 instead. Risk Factor: Medium / CVSS Base Score : 2 (AV:R/AC:L/Au:NR/C:P/A:N/I:N/B:N) I have tried to change SSLProtocol all -SSLv2 to SSLProtocol -ALL +SSLv3 +TLSv1 And SSLCipherSuite ALL:!ADH:!EXPORT:!SSLv2:RC4+RSA:+HIGH:+MEDIUM:+LOW To SSLCipherSuite ALL:!ADH:RC4+RSA:+HIGH:!MEDIUM:!LOW:!SSLv2:!EXPORT But using SSLdigger, it shows the same result. Is this the right way to do something like this?

  • Ubuntu Equivalent of Unix Command cp -n

    - by Ted Karmel
    A software I need to install on my Ubuntu Hardy has a MAKE file which includes the command cp -n. However, I get an error stating the -n is an invalid option. The command will work on a Mac terminal but I need it to work on Ubuntu. Does anyone know the equivalent command for Ubuntu? Thanks.

  • OpenBSD ftp-proxy behind NAT itself

    - by Manuel Faux
    Is it possible to change the PASV IP ftp-proxy of OpenBSD sends to clients, without changing the listen address of redirection control (-b <address>)? I have the following setup: FTP client --> 1:1 NAT router --> OpenBSD router --> FTP server The 1:1 NAT router has a NAT rule to forward everything to the OpenBSD router, the OpenBSD router runs the ftp-proxy -R <FTP server IP>. When the FTP client sends the PASV command, the proxy answers with the Entering Passive Mode (227) message with his own source IP on the interface to the 1:1 NAT router (obviously). Since the 1:1 NAT router is not protocol aware, it forwards this message and the client receives the message with the PASV IP of the OpenBSD router, which it does not have a route to. Is there a way, that I can tell ftp-proxy to send the Entering Passive Mode message with a different source IP?

  • Is it still "wrong" to require TLS on incoming SMTP messages

    - by jackweirdy
    According to the STARTTLS Spec Section 5: A publicly-referenced SMTP server MUST NOT require use of the STARTTLS extension in order to deliver mail locally. This rule prevents the STARTTLS extension from damaging the interoperability of the Internet's SMTP infrastructure. A publicly-referenced SMTP server is an SMTP server which runs on port 25 of an Internet host listed in the MX record (or A record if an MX record is not present) for the domain name on the right hand side of an Internet mail address. However, this spec was written in 1999, and considering it's 2014, I'd expect most SMTP clients, servers, and relays to have some kind of implementation of STARTTLS. How much email can I expect to lose if I require TLS for incoming messages?

  • Wrong DNS for just one site on development machine

    - by Patrick
    www.superyoink.de is my clients' website. I can access it from any machine except my development one. If I ping it on my development machine, I get 80.67.28.107 - this is wrong. My laptop, next to me, is able to resolve it correctly. I have tried putting correct address into hosts like so: 93.187.232.191 www.superyoink.de Still resolves to wrong address. I can enter bogus DNS server addresses so nothing works. But www.superyoink.de still resolves to 80.67.28.107. Rebooted, did ipconfig /flushdns nothing seems to work. I run 32 bit Vista. My impression is that it has stored the wrong dns resolution somewhere and is not even trying the DNS servers. But where? Help please!

  • Modify HTML Content with Squid

    - by user38400
    We have setup our network as per the tutorial here: https://help.ubuntu.com/community/Upside-Down-TernetHowTo. Basically, we have a squid proxy that inverts images for pages that clients request. We're trying to modify the script so that we can edit the contents of the webpage before the webpage is sent to the client. We are not having any luck. I'm wondering if there is something different about .html files that makes this not possible. What is happening is that we do a wget on the URI that is requested, save it locally, modify it and then echo back the new URI. The page that the user gets is the unmodified page and not the one that we just changed.

  • Securing RDP access to Windows Server 2008 R2: is Network Level Authentication enough?

    - by jamesfm
    I am a dev with little admin expertise, administering a single dedicated web server remotely. A recent independent security audit of our site recommended that "RDP is not exposed to the Internet and that a robust management solution such as a VPN is considered for remote access. When used, RDP should be configured for Server Authentication to ensure that clients cannot be subjected to man-in-the-middle attacks." Having read around a bit, it seems like Network Level Authentication is a Good Thing so I have enabled the "Allow connections only from Remote Desktop with NLA" option on the server today. Is this acion enough to mitigate the risk of a Man-in-the-Middle attack? Or are there other essential steps I should be taking? If VPN is essential, how do I go about it?

  • Setting up SSL with 389 Directory Server for LDAP authentication

    - by GioMac
    I've got 389 Directory Server running on RHEL 5 with groups, users, posix etc. RHEL clients are authenticating users with LDAP - no problems, everything works perfect, but passwords are sent in plaintext and are visible with network sniffer. So, decided to run with SSL: Created CA - got both private and public CA certificates Using CA certs: generated both of private and public certificates and combined (1st file) for 389DS according to 389DS certificate request, imported with CA public cert to 389DS from graphical console (2nd file). Enabled SSL in 389DS On the client, using authconfig-gtk enabled SSL for LDAP, specified only CA public certificate Doesn't work. Howto? What is the best way to integrate safely?

  • Macbook memory upgrade question

    - by James Evans
    I've read some conflicting articles on Macbooks and memory upgrades. Some say you have to buy the "special" Mac memory (bulls$%t), others say manufacturers like Partriot and Ocz will work fine. My Macbook (non-pro) is about 6 mos old with it's 2 GB of memory (SO-DIMM 1066MHz DDR3). Does anyone have any definitive information of what will work? Thanks!

  • Can't import matplotlib

    - by None
    I installed matplotlib using the Mac disk image installer for MacOS 10.5 and Python 2.5. I installed numpy then tried to import matplotlib but got this error: ImportError: numpy 1.1 or later is required; you have 2.0.0.dev8462. It seems to that version 2.0.0.dev8462 would be later than version 1.1 but I am guessing that matplotlib got confused with the ".dev8462" in the version. Is there any workaround to this?

  • SQL Server 2008 lincensing question relating to web servers

    - by Matty Brown
    We purchased SQL Server 2008 Standard licences last year under the server + device CAL licencing model. Since our server has 2 physical CPUs and only 46 clients, this option was by far the cheapest. Now we'd like to be able to query a small number of stored procedures from our Windows Server 2003 Web Edition server, which is in a seperate zone on our firewall. I think SQL Server 2008 Web Edition could be an option to us, but is it possible to replicate/mirror stored procedures and tables to such a server and would we be breaking any rules by doing so? Is this a form of multiplexing? Also, would replication/mirroring work both ways, if we were to want to write back data from the web server?

  • Simple NNTP client for Ubuntu

    - by Alexander Gladysh
    I need to download a particular NNTP group. I do not need to setup any crons, put group contents in /opt and other stuff. Just run <fetch-nntp> <server> <group-name> <output-dir> and be done with it without putting a lot of garbage in the system. If that <fetch-nntp> would not fetch the same messages on the second run — fine. But I can live without it. All NNTP clients that I've looked at are trying to be a NNTP server as well. Is there something simpler that is suitable for my needs?

  • Spoof user agent for GoGo Inflight Internet?

    - by AndyL
    Is it possible to trick the GoGo Inflight WiFi on airlines into thinking that you have a mobile device instead of a laptop? It seems like most airlines that offer in flight wireless these days use GoGo. They offer different pricing for mobile and laptops. It seems like they are checking the browser's user agent. Out of curiosity, is it possible to use a Firefox extension like this one to spoof the user-agent and allow a laptop to access the internet under a GoGo mobile plan? How would GoGo handle something like an IMAP email client, like Thunderbird. Do IMAP clients have a user-agent field as well that would normally identify whether the mail client is running on a laptop or mobile device?

  • Centralize proxy settings for all the application on my workstation

    - by Leonardo
    As a consultant, I used to work at different clients premises. It happens frequently that most of them has specific proxy settings, but not all the application I have installed on my laptop get settings from system preferences, for allowing me to change settings in one place. Some of them bypass system preferences completely, proposing their own mask for entering specific data such as username, host and password. I am looking for a convenient and not much intrusive way to share a common access point on which I could enter data, and maybe persist them. An 'automatic' switching would be ideal, for example based on some network identification, but there's no problem for me to enter data manually. I am not an IT expert, but to explain myself clearly, I am looking for a solution like .pac file is for browsers. Relevant OS I am using are MacOSX and Linux (Ubuntu).

  • prevent search engines indexing depending on domain

    - by Javier
    We have a dedicated server with a hosting company with a couple of dozens of webs in it. It happens that the nameservers (EG: ns1.domain.com, ns2.domain.com) ip's are coincident with some client webs, let's say webclient1.com and webclient2.com Problem is that for a certain searches in google, some results are showing up like ns1.domain.com/result instead of webclient1.com/result which is pretty wrong and annoying for our clients. Actually if you type in the browser ns1.domain.com or ns2.domain.com it will load some pageclients instead. Is there any way to prevent google to track those results only in case the robots are coming to check ns domains? It may be not correct to ask this as well, but why is it happening? is it a result of a bad server configuration? I'm pretty new on these matters, so thank you in advance for any help!

  • Printing with an Eclipse RCP program

    - by Raven
    Hi, I am looking for a good, standard way to generate "output" in my RCP programm and print it. This should work as it works on Windows, Mac OS and Linux with the standard print dialog. I am aware of the Birt project, but I could not find any hints about how to implement it within a RCP programm and how to invoke the standard print dialog and how to pass the Birt generated report to the printer. Happy for all hints.

  • IP stops working from time to time

    - by Mattias
    Hi, have a problem that I can't seem to find the reason for. We are running a small network with windows clients(XP/Win7) and windows servers(2008 sp2/2008r2). The domaincontroller is working as DC, DNS, DHCP, VPN. We have a Level1 FBR4000 between internet and our internal network. The problem is that from time to time specific IP-adresses stops working, the only way I have gotten the devices to work again is to exclude the specific IP from the DHCP address pool and getting a new IP, then everything works again. It seems as the specific IP is beeing banned/blocked somewhere but I just can't figure out where. Anyone got an idea as to where I should start to look? I could also point out that I just reinstalled all servers due to a officemove and was hoping to get away from this problem but it just showed up again. This last time it was my iPhone that got stuck through the Wi-Fi...

  • Virus blocking incoming connections ?

    - by Benoît
    Hello, on my windows 2003 server, all incoming connections are dropped. I can see them getting in using Wireshark, but even a single ping from another computer fails. All locally initiated connection work fine (i'm asking from the server). This server is the DC/DHCP/DNS/File server, so computer clients are in the dark. I've run varius antivirus and removal tools without any luck. The Windows Firewall is disabled. I'm wild-guessing at some virus/worm. How can i check why these incoming ICMP/TCP SYN/etc are dropped ? Anyone has any knowledge about such situations ? Thanks.
