  • Is there a tool that can test what SSL/TLS cipher suites a particular website offers?

    - by Jeremy Powell
    Is there a tool that can test what SSL/TLS cipher suites a particular website offers? 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?

  • Parallel port blocking

    - by asalamon74
    I have a legacy Java program which handles a special card printer by sending binary data to the LPT1 port (no printer driver is involved, the Java program creates the binary stream). The program was working correctly with the client's old computer. The Java program sent all the bytes to the printer and after sending the last byte the program was not blocked. It took an other minute to finish the card printing, but the user was able to continue the work with the program. After changing the client's computer (but not the printer, or the Java program), the program does not finish the task till the card is ready, it is blocked until the last second. It seems to me that LPT1 has a different behavior now than was before. Is it possible to change this in Windows? I've checked BIOS for parallel port settings: The parallel port is set to EPP+ECP (but also tried the other two options: Bidirectional, Output only). Maybe some kind of parallel port buffer is too small? How can I increase it?

  • Time drift in Cloud Server - need to mainpulate GRUB config

    - by Aditya Advani
    We are hosting a VPS on a popular host and are experiencing a regular time drift of several minutes a day forward (approx 7). Linux Kernel: 2.6.18-164.11.1.el5 GNU/Linux Distro: CentOS release 5.4 (Final) We reached out to our hosting provider and their support advised us " This is a known issue with Cloud Servers. To fix this you will need to add one line to your grub config located at: /boot/grub/menu.lst The line you need to add is: noapic nolapic divider=10 nolapic_timer This should correct this issue. You will need to restart after this is added in. " Because I am wary of manipulating grub, mostly I'm terrified that our server may fail to restart - I ask you guys, the pro *nix admins - where exactly in this file does the recommended insertion below: # line from 1&1 for time syncing issue (Case 5163) noapic nolapic divider=10 nolapic_timer go? Please specify where exactly, and whether the order of commands is or is not important. Why is the block below "title CentOS ..." indented? If someone could give me an overview of how this works or point me to a resource that's easy to follow, that's what I'm looking for immediately, a light overview or basic understanding of what I;m doing. If GRUB and bootloaders are a deep dark treasure trove of kernel hacking or something, that's great well-recommended in-depth resources are also very welcome. This is my current /boot/grub/menu.lst # grub.conf generated by anaconda # # Note that you do not have to rerun grub after making changes to this file #boot=/dev/sda # serial --unit=0 --speed=57600 terminal --timeout=5 serial console timeout=5 title CentOS (2.6.18-164.11.1.el5) root (hd0,0) kernel /boot/vmlinuz-2.6.18-164.11.1.el5 ro root=/dev/hda1 console=tty0 console=tty initrd /boot/initrd-2.6.18-164.11.1.el5.img MOST IMPORTANT: I need to know where in the file above it is appropriate to paste the suggested line so I can confidently restart my VPS after manipulating GRUB config

  • How to use most of memory available on MySQL

    - by Zilvinas
    I've got a MySQL server which has both InnoDB and MyISAM tables. InnoDB tablespace is quite small under 4 GB. MyISAM is big ~250 GB in total of which 50 GB is for indexes. Our server has 32 GB of RAM but it usually uses only ~8GB. Our key_buffer_size is only 2GB. But our key cache hit ratio is ~95%. I find it hard to believe.. Here's our key statistics: | Key_blocks_not_flushed | 1868 | | Key_blocks_unused | 109806 | | Key_blocks_used | 1714736 | | Key_read_requests | 19224818713 | | Key_reads | 60742294 | | Key_write_requests | 1607946768 | | Key_writes | 64788819 | key_cache_block_size is default at 1024. We have 52 GB's of index data and 2GB key cache is enough to get a 95% hit ratio. Is that possible? On the other side data set is 200GB and since MyISAM uses OS (Centos) caching I would expect it to use a lot more memory to cache accessed myisam data. But at this stage I see that key_buffer is completely used, our buffer pool size for innodb is 4gb and is also completely used that adds up to 6GB. Which means data is cached using just 1 GB? My question is how could I check where all the free memory could be used? How could I check if MyISAM hits OS cache for data reads instead of disk?

  • How can I view the binary contents of a file natively in Windows 7? (Is it possible.)

    - by Shannon Severance
    I have a file, a little bigger than 500MB, that is causing some problems. I believe the issue is in the end of line (EOL) convention used. I would like to look at the file in its uninterpreted raw form (1) to confirm the EOL convention of the file. How can I view the "binary" of a file using something built in to Windows 7? I would prefer to avoid having to download anything additional. (1) My coworker and I opened the file in text editors, and they show the lines as one would expect. But both text editors will open files with different EOL conventions and interpret them automagically. (TextEdit and Emacs 24.2. For Emacs I had created a second file with just the first 4K bytes using head -c4096 on a linux box and opened that from my windows box. I attempted to use hexl-mode in Emacs, but when I went to hexl-mode and back to text-mode, the contents of the buffer had changed, adding a visible ^M to the end of each line, so I'm not trusting that at the moment. I believe the issue may be in the end of line character(s) used. The editors my coworker and I tried (1) just automagically recognized the end of line convention and showed us lines. And based on other evidence I believe the EOL convention is carriage return only. (2) return only. are able to recognize and To know what is actually in the file, I would like to look at the binary contents of the file, or at least a couple thousand bytes of the file, preferablely in Hex, though I could work with decimal or octal. Just ones an zeros would be pretty rough to look at.

  • openssl client authentication error: tlsv1 alert unknown ca: ... SSL alert number 48

    - by JoJoeDad
    I've generated a certificate using openssl and place it on the client's machine, but when I try to connect to my server using that certificate, I error mentioned in the subject line back from my server. Here's what I've done. 1) I do a test connect using openssl to see what the acceptable client certificate CA names are for my server, I issue this command from my client machine to my server: openssl s_client -connect myupload.mysite.net:443/cgi-bin/posupload.cgi -prexit and part of what I get back is as follow: Acceptable client certificate CA names /C=US/ST=Colorado/L=England/O=Inteliware/OU=Denver Office/CN=Tim Drake/[email protected] /C=US/ST=Colorado/O=Inteliware/OU=Denver Office/CN=myupload.mysite.net/[email protected] 2) Here is what is in the apache configuration file on the server regarding SSL client authentication: SSLCACertificatePath /etc/apache2/certs SSLVerifyClient require SSLVerifyDepth 10 3) I generated a self-signed client certificate called "client.pem" using mypos.pem and mypos.key, so when I run this command: openssl x509 -in client.pem -noout -issuer -subject -serial here is what is returned: issuer= /C=US/ST=Colorado/O=Inteliware/OU=Denver Office/CN=myupload.mysite.net/[email protected] subject= /C=US/ST=Colorado/O=Inteliware/OU=Denver Office/CN=mlR::mlR/[email protected] serial=0E (please note that mypos.pem is in /etc/apache2/certs/ and mypos.key is saved in /etc/apache2/certs/private/) 4) I put client.pem on the client machine, and on the client machine, I run the following command: openssl s_client -connect myupload.mysite.net:443/cgi-bin/posupload.cgi -status -cert client.pem and I get this error: CONNECTED(00000003) OCSP response: no response sent depth=1 /C=US/ST=Colorado/L=England/O=Inteliware/OU=Denver Office/CN=Tim Drake/[email protected] verify error:num=19:self signed certificate in certificate chain verify return:0 574:error:14094418:SSL routines:SSL3_READ_BYTES:tlsv1 alert unknown ca:/SourceCache/OpenSSL098/OpenSSL098-47/src/ssl/s3_pkt.c:1102:SSL alert number 48 574:error:140790E5:SSL routines:SSL23_WRITE:ssl handshake failure:/SourceCache/OpenSSL098/OpenSSL098-47/src/ssl/s23_lib.c:182: I'm really stumped as to what I've done wrong. I've searched quite a bit on this error and what I found is that people are saying the issuing CA of the client's certificate is not trusted by the server, yet when I look at the issuer of my client certificate, it matches to one of the accepted CA returned by my server. Can anyone help, please? Thank you in advance.

  • How to collect the performance data of a server during an unreachable/down period using Nagios?

    - by gsc-frank
    Some time services and host stop responding due to a poor server performance. I mean, if for some reason (could be lot of concurrency services access, a expensive backup execution on the server or whatever that consume tons of server resources) a server performance is very degraded, that could lead that the server isn't capable to establish any "normal network communication" (without trigger whatever standards timeouts defined for such communication). Knowing host's performance data (cpu, memory, ...) in case of available during that period (host is not down and despite of its performance degradation still allow plugins collect performance data) could be very useful for sysadmin to try to determine what cause the problem, or at least, if the host performance was good and don't interfered at all in the host/service down. This problem could be solved using remote active (NRPE) or remote passive (NSCA) if such remote solutions could store (buffered) perf data to be send to central Nagios server when host performance or network outage allow it. I read the doc of both solutions and can't find any reference to such buffer mechanism neither what happened in case that NSCA can't reach Nagios server. Any idea of how solve this lack of info? so useful for forensic analysis. EDIT: My questions isn about which tools I can use to debug perf problems or gather perf data to analysis, but is about how collect (using Nagios) host perf data even during a network outage for its posterior analysis (kind of forensic analysis). The idea is integrate such data to Nagios graphers like pnp4nagios and NagiosGrapther. I know that I could install tools like Cacti in each of my host, and have a kind of performance data collection redundancy, but I really want avoid that and try to solve all perf analysis requirements with one tools: Nagios

  • Mouse click-focus wanders in vmPlayer 3.0 dual-monitor

    - by Gary M. Mugford
    Previously, a WinXPSP3 session running on a WinXPSP3 host computer ran perfectly fine in a dual monitor setup. No issues with vmPlayer 2.x. BEFORE updating to vmPlayer 3, the following problem cropped up. When clicking in a single monitor, you would get exactly what you expected. However, when the display was stretched across two monitors, the clicking would be to the left of the mouse cursor. The farther RIGHT you were, the farther left the click would occur. In other words, if you clicked on the system menu of a window in the upper left of a window on the left monitor, you would get the system menu. Move half a screen to your right and the click would be on an item about a quarter of the way over, rather than where you were clicking. And by going all the way to the far right of the right monitor, you could bring up a right-click menu on the far right of the LEFT monitor. I Hope I have described this properly. It's confusing, even in words. In single monitor mode, everything works perfectly fine. If, instead of using either UltraMon or DisplayFusion, you run a single desktop across both monitors (3200x1600), there are no mousing issues. Unfortunately, having two 1600x1200 monitors, that depth of 1600 makes that hack less than useable. My graphic card won't offer anything resembling 3200x1200. vmPlayer 3.0 did not alleviate the situation. The microsoft mouse drivers are up to date and so are the nVidia card drivers. Any ideas?

  • Backup, Migrate or Clone Failing CentOS 4 (LVM)

    - by Hegelworm
    Hello there, I've been running a BlueQuartz CentOS 4 system (Nuonce.net distro) for a few years now and although the hard drive (Deskstar) has always been a bit noisy, on a few recent occasions I've heard it having trouble spinning up. Basically, I want to clone this drive to a similar sized one (80 Gig). I've spent many hours reading upon dd, dd_rescue, rsync, clonezilla and LVM mirroring yet the sheer number of options and nightmarish accounts has left me frozen - unable to make an informed decision as to how to start. I've made a few attempts. dd failed after about 2 hours, as, although the drives appeared to be identical on the surface (ATA Seagate Barracudas, Thai not Chinese), the destination drive is slightly smaller. My most recent attempt involved using a Debian CD to format the new drive and then rsync-ing everything over and editing the new drive's grub and fstab to reflect the changes. No joy here either as I hadn't chosen LVM when partitioning the destination drive and it wouldn't boot. As you can probably tell, I'm out of my depth here and a panic-invoking mixture of caution and frustration has prompted me to sign up here. The server itself, although not strictly a production environment, has a very specific installation of Festival, LAME and ffMpeg and provides the back-end for a Text-to-Speech jQuery plugin that I've built over the last 2 years. I'm also planning to rebuild the whole TTS system on Debian as the existing CentOS system still has PHP4 etc. For now though, I'd really like to just shift everything over to a new drive. As this is my first post, please feel free to lay any house rules on me that I might've overlooked; I've been hovering around StackOverflow for a while now but have only just signed up. Many thanks.

  • Xvnc4 started from xinetd only displays empty gray X screen

    - by Scott Thomason
    Hi. I'm attempting to setup an Ubuntu 10.10 box so that anyone can connect to port 5900 and be greeted by the gdm login manager. To do so, I added a vnc entry in /etc/services and I am starting Xvnc4 using this xinetd config file: service vnc { protocol = tcp socket_type = stream wait = no user = nobody server = /usr/bin/Xvnc server_args = -geometry 1000x700 -depth 24 -broadcast -inetd -once -securitytypes None } This kind of works...I can start multiple sessions all to port 5900, and I get an X screen. The problem is that I only get an empty, gray X screen with no applications started. I know when you run vncserver from the command line it will look to your ~/.vnc/ directory for your passwd and xstartup files, and I think what I want to do is put "gnome-session" into the xstart file. However, which xstartup file? The running user is "nobody" who obviously doesn't have a ~/.vnc/ directory. I tried a /root/.vnc/xstartup file and a ~scott/.vnc/xstartup file and it doesn't look like they were even read. I changed the xinetd vnc service so that it would "strace" Xvnc4. I looked thru all the "open" lines and didn't get a clue as to what file it was trying to read for xstart. Can anyone help? I just want a terminal server where the user is presented with a gdm login screen.

  • Ubuntu server PPTPD with OS X clients Problems

    I'm trying to get a PPTP server running on a ubuntu server, but I've run into some issues with it. I followed this guide on how to set up pptpd on my server, and everything went smooth, but when I try to connect with my mac, it gives me this error: Here's my configuration: Does anyone have any idea as to what I'm doing wrong here?

  • PPTP server connection closes - Too much data?

    - by Sebastian Hoitz
    I set up a PPTP server for my company. However, every time I have another computer connected to this server (i.e. our backup server) and a lot of data gets transferred, the connection to this computer closes. In the syslog on the PPTP server I find this message: Apr 22 12:44:34 komola-chase pptpd[2581]: CTRL: Reaping child PPP[2583] Apr 22 12:44:34 komola-chase pppd[2583]: MPPE disabled Apr 22 12:44:34 komola-chase pppd[2583]: Connection terminated.

  • Ubuntu 11.10 Virtual-box Unity 3D not working

    After struggling for four hours, I still cannot get Unity 3D of Gnome 3 to work on my VirtualBox - I have been pouring through Internet and forum posts but to no avail. Here's what I've done so far: VirtualBox 4.1.4r74921 on Windows 7 Installed Ubuntu Desktop 11.10 ( 32 bit ) Enabled 3D acceleration Allocated 1.5GB of RAM Allocated 50MB video memory (hope this is not the culprit) Installed Guest edition 4.1.4 Did apt-get update and apt-get upgrade Booted back in to Ubuntu - falls back to Unity 2D Shared folder, mouse integration all works, so guest edition is properly installed Tried the command and below is the output /usr/lib/nux/unity_support_test –p OpenGL vendor string: Mesa Project OpenGL renderer string: Software Rasterizer OpenGL version string: 2.1 Mesa 7.11 Not software rendered: no Not blacklisted: yes GLX fbconfig: yes GLX texture from pixmap: no GL npot or rect textures: yes GL vertex program: yes GL fragment program: yes GL vertex buffer object: yes GL framebuffer object: yes GL version is 1.4+: yes Unity 3D supported: no I am trying to find what the "no" means but cannot find any good answers.

  • Google Chrome - Issues with download dialogs using BinaryWrite

    - by Mila
    Hello, I have an empty ASP .NET page with the code behind to support downloading of PDF files. The page is called from a link-like web control that has NavigateUrl set to this page. In short, I am using the following for streaming: Response.Buffer = false; Response.ClearHeaders(); Response.ContentType = "application/x-pdf"; Response.AddHeader("Content-Disposition","attachment; filename="MyPDFFile.pdf"); byte[] binary = (dataReaderRemote[DataPDFFieldName]) as byte[]; //dataReaderRemote[DataPDFFieldName] has previously retrieved data if (binary != null) { MemoryStream memoryStream = new MemoryStream(binary); int sizeToWrite = CHUNKSIZE; //CHUNKSIZE=1024 for (int i = 0; i < binary.GetUpperBound(0) - 1; i = i + CHUNKSIZE) { if (!Response.IsClientConnected) return; if (i + CHUNKSIZE >= binary.Length) sizeToWrite = binary.Length - i; byte[] chunk = new byte[sizeToWrite]; memoryStream.Read(chunk, 0, sizeToWrite); Response.BinaryWrite(chunk); Response.Flush(); } } Response.Close(); IE as well as Firefox bring the download prompt window asking you whether you wish to open or save the file, while the user remains on the same page containing the link. However, Google Chrome opens a new blank tab and downloads the file automatically. Is there any way to prevent Chrome from opening the extra blank and therefore useless tab? I am using the Google Chrome version 5.0.375.55 (Official Build 47796) on Windows XP. Thanks in advance! Mila

  • Windows Server 2008 network speed slow, Xen 3.4.3 HVM ISO

    - by Elliot.Bradshaw
    I've setup a VM running Windows Server 2008 on a host node running Xen 3.4.3-5 and the following kernel: 2.6.18-308.1.1.el5xen #1 SMP Wed Mar 7 05:38:01 EST 2012 i686 i686 i386 GNU/Linux The network speed on the VM is very slow--using the online speed tests I can only get it up to 8-9mbps. The line is 100mbps burstable and the host node has no problem achieving those speeds. If it setup a VM running CentOS, it too has no problems achieving those speeds. I've done some pretty exhaustive troubleshooting, but nothing has helped: New VM installations of Win2k8 do have the same network problem. Upgrading to most recent kernel-xen did not help (2.6.18-308.1.1.el5xen). Upgrading from xen 3.4.0 to xen 3.4.3-5 did not help. Disabling Windows firewall, etc did not help. Changing network card device config from auto negotiation to manually be 100mbps full duplex did not help. Changing the network receive buffer packet size did not help (tried all combos from 64k to 8k). At this point I'm pretty much out of ideas--any help would be appreciated!

  • Apache + Codeigniter + New Server + Unexpected Errors

    - by ngl5000
    Alright here is the situation: I use to have my codeigniter site at bluehost were I did not have root access, I have since moved that site to rackspace. I have not changed any of the PHP code yet there has been some unexpected behavior. Unexpected Behavior: http://mysite.com/robots.txt Both old and new resolve to the robots file http://mysite.com/robots.txt/ The old bluehost setup resolves to my codeigniter 404 error page. The rackspace config resolves to: Not Found The requested URL /robots.txt/ was not found on this server. **This instance leads me to believe that there could be a problem with my mod rewrites or lack there of. The first one produces the error correctly through php while it seems the second senario lets the server handle this error. The next instance of this problem is even more troubling: 'http://mysite.com/search/term/9 x 1-1%2F2 white/' New site results in: Bad Request Your browser sent a request that this server could not understand. Old site results in: The actual page being loaded and the search term being unencoded. I have to assume that this has something to do with the fact that when I went to the new server I went from root level htaccess file to httpd.conf file and virtual server default and default-ssl.

This violates # the SSL/TLS standard but is needed for some brain-dead browsers. Use # this when you receive I/O errors because of the standard approach where # mod_ssl sends the close notify alert. # o ssl-accurate-shutdown: # This forces an accurate shutdown when the connection is closed, i.e. a # SSL close notify alert is send and mod_ssl waits for the close notify # alert of the client. This is 100% SSL/TLS standard compliant, but in # practice often causes hanging connections with brain-dead browsers. Use # this only for browsers where you know that their SSL implementation # works correctly. # Notice: Most problems of broken clients are also related to the HTTP # keep-alive facility, so you usually additionally want to disable # keep-alive for those clients, too.

  • Parental Controls in Ubuntu - per user

    - by Hamish Downer
    I would like to set up parental controls on Ubuntu for a friend of mine. I want it so that the child user has the controls set, but the parent user is not restricted. To be clear, they are sharing one computer, so a router based solution won't help. And I would like a set of step by step instructions to do this. Just one way of doing it. I'm an experienced Ubuntu user, happy at the command line. I've spent quite some time googling for this along the way. I hope that the GChildCare project will eventually make this easy, but it is not ready yet. In the meantime, the WebContentControl GUI provides a way of managing parental controls, but apply them to every user on the computer (easy WebContentContol install instructions and detailed instructions, discussion and related links on ubuntuforums). The ubuntuforums post has a FAQ that states that user-specific configuration is not possible with WebContentControl, and then provides 3 links he used to help him do it. But they are far from step by step instructions. There is this thread which is notes along the way and linking to this article about squid and dansguardian. And then to these two dansguardian articles which are somewhat in depth ... So does anyone know of an existing guide to how to set up parental controls on ubuntu with some users not affected? If no one has come up with an answer after a little bit, I'll set up a community wiki answer so we can come up with a guide.

  • Which IP should I use for my nameserver

    - by Luke Bream
    Sorry to ask whats probably very obvious question. I have just got a new server that is fantastically cheap but unfortunatly doesnt come with any technical support and Im very out of my depth ! My hosting company has provided the following information... Below you will find your additional IP addresses added to the server 5.9.36.51 Please note that you can use the subnet only for this server. IP: 5.9.225.64 /27 Mask: 255.255.255.224 Broadcast: 5.9.225.95 Useable IP addresses: 5.9.225.65 to 5.9.225.94 It has cPanel with WHM and im going through the setup... I have a number of questions... my domian is purchased from godaddy and I want to use it as the name server. Question 1: Which IP or IP's do I enter into the godaddy interface for ns1.mydomian.com ns2.mydomain.com Question 2: In the WHM nameserver setup what do I enter for... Please enter an IP address for each of your nameservers. ns1.mydomain.com ?????? ns2.mydomain.com ?????? Add "A Entries" for Hostname IP for Entry: ????????? Thanks for aany help you can give Luke

  • Hard wrapping in vim without joining

    - by Miles
    Vim newbie here. How can I hard wrap plain text in vim (inserting actual linebreaks), respecting word boundaries, without joining existing lines? For example, given this: Lorem ipsum dolor sit amet, consectetur adipiscing elit. - Nulla cursus accumsan faucibus. - Donec dapibus dignissim ullamcorper. Integer nec malesuada diam. I'd like to get (with textwidth=30): Lorem ipsum dolor sit amet, consectetur adipiscing elit. - Nulla cursus accumsan faucibus. - Donec dapibus dignissim ullamcorper. Integer nec malesuada diam. instead of this (which I can get with gggqG) Lorem ipsum dolor sit amet, consectetur adipiscing elit. - Nulla cursus accumsan faucibus. - Donec dapibus dignissim ullamcorper. Integer nec malesuada diam. Also, for bonus points: when I create a brand new buffer, I get different wrapping behavior (lines beginning with - aren't wrapped specially) than when I open a file ending in .txt. What controls this? I don't notice any difference in the output of :set filetype? or :filetype.

  • How to verify a self-signed certificate from another server using openssl?

    - by ntsue
    I am new to openssl and I am having some trouble verifying (from a client machine) an ftp server using ssl with a self-signed certificate. I generated the .cer file by going to my server in IIS and exporting the certificate without the private key. I believe that this is all that I should need on the client side, right? I use the following code to verify the certificate openssl verify ftp.cer and the error that I get back is error 20 at 0 depth lookup:unable to get local issuer certificate I tried this as well: openssl verify -CAfile ftp.cer ftp.cer but received the same error. From what I understand about SSL, this is happening because I have no chain of trust that connects to this server. By default, openssl did not install any trusted CAs and this is fine. I would just like to tell it to trust this server. I tried various tutorials telling me how to add a certificate authority, including this one here, however the instructions are for linux and include adding a symlink and I am trying to do this in windows. If anyone could provide any guidance on how to do this, or enlighten me if I am not understanding something correctly, I would greatly appreciate it. Thanks!
