• Chrome - SSL Security issue on Windows platforms?

  - by al nik

  Fortify.net is a service that displays what's the currently encryption key used by your browser in a https connection. If I browse this site with Chrome 4.1.249.1042 in WinXp SP3 the key used is RC4 cipher, 128-bit key This encryption is weak, and it's the one used by old browsers like IE6. Chrome works fine on Fedora9 and it uses AES cipher, 256-bit key as more modern browsers do (i.e.Firefox) I consider this a security issue. I'm considering to switch back to Firefox in Windows. Do you know if it's possible to change the default encryption key in Chrome?

• How to consolidate servers with the not-very-strong infrastructure

  - by Sim

  All, Situation We are in retail industry with about 10 distributors and use Solomon as the standard ERP for all our systems Each distributor has 1 HQ and 5 - 10 branches, each branch has their own server (Windows 2000/XP/2003 + Solomon + another built-in POS system) Everyday, branches has to extract data and send (via email/Skype) to HQ for data consolidation purpose When we first deployed our ERP, the infrastructure (e.g. Internet connection) wasn't reliable enough. That's why we went with the de-centralized model (each branch got their own server) Now, the infrastructure is mature already. And we need to consolidate data more quickly (not from branches -- HQ -- our company but something like HQ -- our company only) Goal We just have Solomon servers in distributor HQ. All the transactions in branches (retrieved from POS) will by synchronized with HQ server directly) There is a backup plan just in case the Internet goes down, or HQ server goes down Question With the above question, could you guys suggests some model for me ? Should we use Terminal services, any other solutions ? Any watchout/suggestions ? Any good article to read 'bout this ? Thanks a lot

• Squid traffic tunneled through VPN

  - by NerdyNick

  So what I'm trying to do is have a Squid Proxy run on 1 machine along side a VPN connection. What I want to happen is all traffic running though the Squad Proxy would run though the VPN for its outbound. ie Desktop - (Squid Proxy - VPN) The goal is to allow my desktop selective tunneling through the VPN. So that Instant Messaging and the like that do not need to run through the VPN can go through my normal traffic. Typically I would go though a SSH Proxy but currently am forced to use VPN to gain entry into the office, and a Squid proxy seemed like it might work out the easiest for what I am needing. EDIT Realize I forgot to actually state what problem I'm running into. I have the Squid setup and verified it works, but once I connect to the VPN. All requests to Squid get accepted but Squid is unable to make the request over the VPN. So the client ends up just sitting there.

• How to block own rpcap traffic where tshark is running?

  - by Pankaj Goyal

  Platform :- Fedora 13 32-bit machine RemoteMachine$ ./rpcapd -n ClientMachine$ tshark -w "filename" -i "any interface name" As soon as capture starts without any capture filter, thousands of packets get captured. Rpcapd binds to 2002 port by default and while establishing the connection it sends a randomly chosen port number to the client for further communication. Both client and server machines exchange tcp packets through randomly chosen ports. So, I cannot even specify the capture filter to block this rpcap related tcp traffic. Wireshark & tshark for Windows have an option "Do not capture own Rpcap Traffic" in Remote Settings in Edit Interface Dialog box. But there is no such option in tshark for linux. It will be also better if anyone can tell me how wireshark blocks rpcap traffic....

• Remote connect into macbook pro at a different resolution

  - by user60277

  Hello, I have a Dell laptop with Windows 7 on it. Its resolution is 1920x1080. I want to connect to a macbook pro at that resolution. The macbook pro has a resolution of 1440x900 so when I VNC into it, I can only see 1440x900 box with black borders on full resolution. The macbook pro can drive resolutions of 2560x1440. What program do I use to connect to the macbook at full (1920x1080) resolution. I can use remote desktop and connect from the dell laptop to another dell laptop that has a 1440x900 max. resolution. However in case of Remote desktop connection I can expand the window to be 1920x1080. I'm using TightVNC viewer on Windows. Thanks

• Install VirtualBox Guest Additions "Feisty Fawn"

  - by codebone

  I am trying to install the virtualbox guest additions into a feisty fawn (7.04) VM. The problem I am running into is that when I Click install guest additions, or place the iso in the drive manually, the disk never shows up in the machine. I even manually mounted and went to the mounted directory and it was empty. When using the file browser, doubling clicking on the cdrom yields Unable to mount the selected volume. mount: special device /dev/hdc does not exist. Secondly, I tried installing via repository... but according to the system, I have no internet connection. But, I can browse the web using firefox just fine (in the guest). Here is my /etc/network/interfaces file... code auto lo iface lo inet loopback auto eth0 iface eth0 inet dhcp I also tryed setting a static ip... auto lo iface lo inet loopback auto eth0 iface eth0 inet static address 192.168.1.253 netmask 255.255.255.0 gateway 192.168.1.1 The reason I am trying to get this particular installation running is because it is part of a book, "Hacking: The Art of Exploitation" (Jon Erickson), and is fully loaded wilh tools and such to go along exactly with the book. I appreciate any effort into finding a solution for this! Thanks

I need the software to enable sharing of a common canvas on which I can draw, write and point to. Say a Microsoft paint canvas on internet. Could you point out a suitable software? Google is not of being help at the moment as I suspect that I am not specifying my search criteria properly.

• How can I allow a linux subversion user to only execute svnserve?

  - by sbleon

  I've got a user that I'd like to only be able to use subversion. We like to use svn+ssh:// URLs sometimes (for public keys and whatnot), so I need them to be able to connect over ssh and run only the svnserve command. When using a svn+ssh URL, svn ssh'es in and passes the arguments "-c svnserve -t". I wrote a custom shell as follows to filter the commands that can be run. This works, but it's not passing the input to svnserve, so when I try to "svn up" I get "svn: Connection closed unexpectedly". #!/bin/bash if [ "$1" == "-c" ] && [ "$2" == "svnserve" ] && [ "$3" == "-t" ] && [ "$4" == ""] ; then exec svnserve -t else echo "Access denied. User may only run svnserve." fi

• How to make phone calls using a phone

  - by user18151

  Hi, I have a phone landline connection and I DO NOT have a phone instrument. I connect the cable into my laptop, and want to make calls using my laptop. I have an HDA CX20561 modem. I seem to be able to dial number using dialer.exe, though nothing seems to happen. From Microsoft kb http://support.microsoft.com/kb/958143, it looks like dialer.exe alone is not enough for the call. Can somebody tell me how to make and receive phone call with whatever hardware I have, i.e. what software will I need. Thanks.

• [SOLVED]Need help with remote dekstop - Limit the computers you can access server from

  - by stirredo

  I have a windows server 2003 computer that is accessed by remote desktop connection. To access the server all you need to know is the IP address of the computer. I want to limit the computers that can access the windows server computer to authorized computers only. The authorized computers won't have static IPs, so I cannot limit them on basis of IP address. Can I limit them on basis of MAC id perhaps? I won't mind using third party solution like Teamviewer or Logmein etc. So How can I solve this problem? EDIT: Found a possible solution in team viewer. Team viewer creates a unique partner ID for the computer it is installed on. It has an option for allowing only authorized partner IDs to access the computer. Problem solved.

• Two Ubuntu Instances (Guest) networking with XP (Host) in virtual box v3.1.4

  - by EnthuCrazy

  So here is my current objective: I need to create two guest instances of Ubuntu Desktop 9.10 in VirtualBox on a WindowsXP host. (This is needed for communications later on.) (this step is almost done) I need to establish networking between all three OS's, the host and two guests (Guest1 - Host - Guest2). I know that generally, to establish networking between Windows host and Ubuntu guest, we set up a bridge connection. But here there are two guests, and primarily I need networking between the two guests (Ubuntu to Ubuntu). So will there need to be a change in tap0 and tap1 interfaces when we set up a bridge, or is there a better way to implement this? Please explain the procedure.

• How to avoid maximum Workgroup Manager connections in Mac OS X Server 10.6

  - by Stephan

  Is there a limit on the Mac OS X Server (10.6) Workgroup Manager in respect to concurrent connections to a server? I have an OS X server up and running and Open Directory configured but I am not able to log in remotely as I get the message the maximum number of connections for Workgroup Manager is already reached and I should wait for a user to disconnect. Even after a restart I get this message remotely. However, locally on the server I can start Workgroup Manager without any issues. It always lets me connect. Any advice what I need to do to make Workgroup Manager work from a remote location? I could not find any max connection setting in Server-Admin and nothing in the slapd log files. The server license says unlimited so I am quite sure it should not be a regular error message that indicates to me I should upgrade.

• Ubuntu 12.04 MySQL 5.5 MyODBC 5.1 or 3.1 query hangs

  - by jorgearr

  I have been able to install Ubuntu 12.04 with LAMP MySQL version 5.5.x It works fine within linux, it allows me to connect from myodbc windows vista or windows 7 I have configured networking access and have been able to access from windows vista using putty and other tcp connections like mysql query browser. I have also configured or disabled ufw firewall and apparmor. The connection works fine until I query data from the tables. It lets me query small amounts of data like: SELECT name FROM users limit 20 but if I do a SELECT * FROM users, it goes on a never-ending loop. This happens even on tables with very few records like 5 or even less. The problems occur with windows because I tried ssh from linux mint and it worked fine. I need to be able to work using MyODBC either 3.51 or 5.1 since my client program is made in VB6 and connects to mysql server via tcp/ip. The server is an HP PROLIANT ML350G6 with Intel Xeon 64 bits. I tried several ubuntu server version (12.04 64bit, 10.10 64bit, 11.04 32bit) and none has worked I even tried CentOS 6.3 and the same. As a reference, it works fine with onother ubuntu server version 6.x on HP Proliant 150 and mysql 5.0.x that is like 7 years old and never updated. Help Please.

• Can't communicate using PuTTY, but can with Termite

  - by SharpHawk

  I'm trying to establish a serial connection to a peripheral from my PC's RS-232 port. Pretty simple stuff, and I've had not trouble doing it with countless peripherals before. And yet when I configure PuTTY to the right baud rate, stop bits, etc. I'll type in "*IDN?", press enter, and the unit won't reply. After going over my settings over and over again, I decided to try another terminal program, Termite. This time it worked like a charm. What puzzles me, and what I'm trying to figure out by posting this question, is why Termite would work when PuTTY did not despite the fact that they both have the same settings. PuTTY: http://www.chiark.greenend.org.uk/~sgtatham/putty/download.html Termite: http://www.compuphase.com/software_termite.htm EDIT: I now tried Tera Term as well, and it works. So PuTTY is the odd one out.

• One of my most frequently used commands

  - by Kevin Smith

  On a Linux or UNIX server this is one of my most frequently used commands. find . -name "*.htm" -exec grep -iH "alter session" {} \; It is an easy way to find a string you know is in a group of files, but don't know or can't remember which file it is in. For the example above, I knew that WebCenter Content sends a bunch of alter session commands to the database when it opens a new database connection. I wanted to find where these were defined and what all the alter session commands were. So, I ran these commands: cd /opt/oracle/middleware/Oracle_ECM1/ucm/idc/resources/core find . -name "*.htm" -exec grep -iH "alter session" {} \; And the results were: ./tables/query.htm: ALTER SESSION SET optimizer_mode = ?./tables/query.htm: ALTER SESSION SET NLS_LENGTH_SEMANTICS = ?./tables/query.htm: ALTER SESSION SET NLS_SORT = ?./tables/query.htm: ALTER SESSION SET NLS_COMP = ?./tables/query.htm: ALTER SESSION SET CURSOR_SHARING = ?./tables/query.htm: ALTER SESSION SET EVENTS '30579 trace name context forever, level 2'./tables/query.htm: ALTER SESSION SET NLS_DATE_FORMAT = ?./tables/query.htm: alter session set events '30579 trace name context forever, level 2' I could then go edit the query.htm file and find the include that contained all the ALTER SESSION commands.

• Why does WebDAV fail from inside home network

  - by Claus

  On my OSX server there is a folder that is configured in the Server App to be accessible via WebDAV. This folder is used to sync OmniFocus. On my router, I have set up a dynamic dns. When I am outside my home network (physically away or when connected via a vpn), I can connect and sync fine via: https://<server name from dyndns>/<username>/<path to WebDAV folder> However, when I am in my home network, the connection to WebDAV does not work (other connections, AFP, f.ex, do work). What could be some reasons why I can't connect to WebDAV from within my home network? What log files could give hints and where are they stored? I am running OSX server 10.9.3. and server.app. Thanks for your help.

• netsh wlan add profile not imported passphrase

  - by sirlancelot

  I exported a wireless network connection profile from a Windows 7 machine correctly connected to a WiFi network with a WPA-TKIP passphrase. The exported xml file shows the correct settings and a keyMaterial node which I can only guess is the encrypted passphrase. When I take the xml to another Windows 7 computer and import it using netsh wlan add profile filename="WiFi.xml", it correctly adds the profile's SSID and encryption type, but a balloon pops up saying that I need to enter the passphrase. Is there a way to import the passphrase along with all other settings?

• Download acceleration with jigdo?

  - by james

  Im using jigdo-lite to download a Debian DVD ISO. I already have the CD version of the image, so I added the CD files to the task. Now I need to download many files (not all) of the DVD ISO. The default jigdo-lite uses wget to download files. It seems jigdo (wget) downloads only one file at a time with one connection. So I'm getting a low download speed. How can I accelerate the download speed using jigdo? Possible Solutions: Using different download manager with jigdo. Is it possible? If yes, How? Using jigdo (wget) to download multiple files at once. How? Getting download links of remaining files to download so that they can be downloaded with a download manager and later added to jigdo iso. How?
