    I've installed Crashplan on my (K)Ubuntu computer.

  • Suspending my laptop breaks ethernet over firewire, are there commands which can fix it?

    - by Josh
    As mentioned in this question I am using a firewire cable to provide a private network between my laptop and my desktop, because it makes using the screen sharing program synergy much nicer than using WIFI. However when I leave my office for the day and I suspend my laptop, when I return the next day, the desktop and the laptop cannot communicate over firewire anymore. The firewire0 device still has an IP address. but when I try and ping the desktop I get no route to host I'm using kernel 2.6.35-24-generic #42-Ubuntu SMP x86_64 on Ubuntu 10.10. Is there some way I can remedy this without a reboot? Like, removing some kernel modules and re-inserting them? Here's what I have tried so far and the results: root@token:~# dmesg|tail -n 1 [592525.204024] firewire_core: phy config: card 0, new root=ffc1, gap_count=5 root@token:~# modprobe -r firewire_net firewire_ohci firewire_core root@token:~# modprobe -v firewire_ohci insmod /lib/modules/2.6.35-24-generic/kernel/lib/crc-itu-t.ko insmod /lib/modules/2.6.35-24-generic/kernel/drivers/firewire/firewire-core.ko insmod /lib/modules/2.6.35-24-generic/kernel/drivers/firewire/firewire-ohci.ko root@token:~# dmesg|tail [592525.204024] firewire_core: phy config: card 0, new root=ffc1, gap_count=5 [592563.410868] firewire_ohci: Removed fw-ohci device.

This did not work either :-(

  • USB mass storage couldn't get mounted

    - by revo
    It's my android phone SD card which was indicated damaged by android yesterday night, out of the blue! I put it directly to a USB port with a USB SD card holder case, so in that way I can recover it with TestDisk, which I had experienced before on a similar situation. I also noticed that there is a change in file system and capacity: File System : RAW Capacity : 0 (unknown capacity) Also TestDisk doesn't show it on its partitions list. A 2 GB SD card is not that important in price but I've a lot of files and medias which I need them. Used a mini card reader, TestDisk displayed it on its list but a quick search and or a deep search doesn't have any results No partition found or selected for recovery and then I should quit the program. Your help is appreciated.

  • Samba new file ownership, permissions configuration

    - by Martin Melka
    I have recently installed Samba on my server. Now I have a question about permissions and how to set it up. Currently I mount the Samba shared drive to my laptop with this line in /etc/fstab: //<host>/share /mnt/melka-server-data/ cifs username=<usrname> password=<passwd> _netdev 0 0 This works, as I can read from the files and create them (as root). The problem is when I want to create files as a regular user. I always get a Permission Denied error. These are ll outputs of the mounted folder: magicmaster@magicmaster-kubuntu:/mnt$ ll total 8 drwxr-xr-x 3 root root 4096 lis 11 14:15 ./ drwxr-xr-x 26 root root 4096 ríj 26 11:01 ../ drwxrwxrwx 8 magicmaster magicmaster 0 lis 12 22:12 melka-server-data/ and the inside: magicmaster@magicmaster-kubuntu:/mnt/melka-server-data$ ll total 4 drwxrwxrwx 8 magicmaster magicmaster 0 lis 12 22:12 ./ drwxr-xr-x 3 root root 4096 lis 11 14:15 ../ drwxrwxrwx 5 magicmaster magicmaster 0 lis 12 09:35 downloads/ drwxrwxrwx 2 magicmaster magicmaster 0 ríj 28 12:57 lost+found/ drwxrwxrwx 15 magicmaster magicmaster 0 lis 12 09:45 movies/ drwxrwxrwx 2 magicmaster magicmaster 0 lis 1 21:15 newest/ drwxrwxrwx 3 magicmaster magicmaster 0 lis 2 23:14 photos/ drwxrwxrwx 2 magicmaster magicmaster 0 ríj 30 12:44 software/ -rw-r--r-- 1 nobody nogroup 0 lis 12 22:12 zdar I called sudo chown -R magicmaster:magicmaster melka-server-data/ to try and change all the files to belong to me. Then the file zdar was created by magicmaster just by calling touch. I got the Permission Denied, but it was still created, though it belongs to nobody and I can't write into it. When I create a file as root, it still belongs to nobody, but at least I can write into it. What am I missing? I didn't notice anything in Samba config that would be related to this and I don't like the idea of having to log on as root in order to copy files.. Thanks

  • DVD wont mount Ubuntu 12.04

    - by CyborgGold
    I can't seem to be able to mount my optical drive. I have tried numerous solutions from this site with no results. I am not able to see the device inside the file browser either. There is a DVD in the drive. I am running 12.04 on an HP g60-235dx portable. I have a link below to the specs. I will also list what I have tried (that I can find back right now.) I know the drive is functioning, because just before Windows 7 crashed and my MBR went fubar I was watching movies just fine. I am fairly new to linux, so don't assume I know anything. Ok, so here is what I have tried: sudo wget --output-document=/etc/apt/sources.list.d/medibuntu.list http://www.medibuntu.org/sources.list.d/$(lsb_release -cs).list sudo apt-get --quiet update sudo apt-get --yes --quiet --allow-unauthenticated install medibuntu-keyring sudo apt-get --quiet update sudo apt-get install libdvdcss2 dmesg | grep sr0 (no output) apt-get install libdvdnav4 (already installed, and up to date) sudo /usr/share/doc/libdvdread4/install-css.sh ls -l /dev/cdrom /dev/cdrw /dev/dvd /dev/dvdrw /dev/scd0 /dev/sr0 ls: cannot access /dev/scd0: No such file or directory lrwxrwxrwx 1 root root 3 Sep 10 03:51 /dev/cdrom -> sr0 lrwxrwxrwx 1 root root 3 Sep 10 03:51 /dev/cdrw -> sr0 lrwxrwxrwx 1 root root 3 Sep 10 03:51 /dev/dvd -> sr0 lrwxrwxrwx 1 root root 3 Sep 10 03:51 /dev/dvdrw -> sr0 brw-rw----+ 1 root cdrom 11, 0 Sep 10 03:51 /dev/sr0 wodim --devices wodim: Overview of accessible drives (1 found) : ------------------------------------------------------------------------- 0 dev='/dev/sg1' rwrw-- : 'TSSTcorp' 'CDDVDW TS-L633M' ------------------------------------------------------------------------- sudo lshw optical *-cdrom description: DVD-RAM writer product: CDDVDW TS-L633M vendor: TSSTcorp physical id: 1 bus info: scsi@1:0.0.0 logical name: /dev/cdrom logical name: /dev/cdrw logical name: /dev/dvd logical name: /dev/dvdrw logical name: /dev/sr0 version: 0200 capabilities: removable audio cd-r cd-rw dvd dvd-r dvd-ram configuration: ansiversion=5 status=nodisc sudo lshw | grep cdrom *-cdrom logical name: /dev/cdrom Spec sheet for portable: http://www.cnet.com/laptops/hp-g60-235dx/4507-3121_7-33496192.html If you need any more information than all of that... please let me know.

  • How to get a *.cer file to add a self-signed HTTPS certificate as trusted for Java

    - by pako
    I'm connecting to a HTTPS website with a self-signed certificate using a Java applet. The applet can't open the HTTPS connection - it returns the following exception: javax.net.ssl.SSLHandshakeException: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target So the problem is that I need to add the certificate as "trusted" for Java. I read that I should use the following command: keytool -import -alias abc -file ABCCA.cer Am I correct? How do I retrieve the *.cer file? The server is running Debian 5. I'm using Windows 7 and Java 6 on the client machine.

  • Can I ensure, using C#, that an X509Certificate was issued by a trusted authority?

    - by dommer
    If I use X509Certificate.CreateFromSignedFile to get the certificate used to sign a file, can I confirm that it was signed by a trusted authority - and isn't just a "self-signed" cert of some kind? I want to extract the "Subject" (company) name from the cert to ensure that an unmanaged DLL I'm using is unmolested (I can't checksum it as it's updated frequently and independently) and official. However, I'm concerned that a fake DLL could be signed with a "self-signed" cert and return the original company's name. So, I want to ensure the the cert was issued by Versign, Thwate or similar (anything installed on the cert repository on the machine will be fine). How can I do this, if at all, when using X509Certificate.CreateFromSignedFile? Or does it do this automatically (i.e. a "self-signed" cert will fail)?

  • how to adjust the size of the root partition on live arch linux system (/dev/mapper/arch_root-image)

    - by leon
    Summary: I created a bootable usb drive with a live Bridge linux (ARCH based) on it. Everything works fine. The live system mounts a device called /dev/mapper/arch_root-image as its ext4 root partition (/ mount point). The problem is that I dont know how to control the size of this partition. This is not a Bridge specific issue (also happens with Archbang) Detail: My usb drive has a dos partition table with 2 ext2 partitions $ fdisk -l /dev/sdb Disk /dev/sdb: 29,8 GiB, 32006733824 bytes, 62513152 sectors Unités : secteur de 1 × 512 = 512 octets Taille de secteur (logique / physique) : 512 octets / 512 octets taille d'E/S (minimale / optimale) : 512 octets / 512 octets Type d'étiquette de disque : dos Identifiant de disque : 0x0007b7e2 Périphérique Amorçage Début Fin Blocs Id Système /dev/sdb1 * 2048 2002943 1000448 83 Linux /dev/sdb2 2002944 32258047 15127552 83 Linux sdb1 is approx 1GB and sdb2 is 14GB. The live system is on sdb1. sdb2 is empty. Now when I boot the live system, its filesystem looks like this: $ mount proc on /proc type proc (rw,nosuid,nodev,noexec,relatime) sys on /sys type sysfs (rw,nosuid,nodev,noexec,relatime) dev on /dev type devtmpfs (rw,nosuid,relatime,size=505272k,nr_inodes=126318,mode=755) run on /run type tmpfs (rw,nosuid,nodev,relatime,mode=755) /dev/sda1 on /run/archiso/bootmnt type ext2 (ro,relatime) cowspace on /run/archiso/cowspace type tmpfs (rw,relatime,size=772468k,mode=755) /dev/loop0 on /run/archiso/sfs/root-image type squashfs (ro,relatime) /dev/mapper/arch_root-image on / type ext4 (rw,relatime) securityfs on /sys/kernel/security type securityfs (rw,nosuid,nodev,noexec,relatime) tmpfs on /dev/shm type tmpfs (rw,nosuid,nodev) devpts on /dev/pts type devpts (rw,nosuid,noexec,relatime,gid=5,mode=620,ptmxmode=000) tmpfs on /sys/fs/cgroup type tmpfs (rw,nosuid,nodev,noexec,mode=755) cgroup on /sys/fs/cgroup/systemd type cgroup (rw,nosuid,nodev,noexec,relatime,xattr,release_agent=/usr/lib/systemd/systemd-cgroups-agent,name=systemd) pstore on /sys/fs/pstore type pstore (rw,nosuid,nodev,noexec,relatime) cgroup on /sys/fs/cgroup/cpuset type cgroup (rw,nosuid,nodev,noexec,relatime,cpuset) cgroup on /sys/fs/cgroup/cpu,cpuacct type cgroup (rw,nosuid,nodev,noexec,relatime,cpuacct,cpu) cgroup on /sys/fs/cgroup/memory type cgroup (rw,nosuid,nodev,noexec,relatime,memory) cgroup on /sys/fs/cgroup/devices type cgroup (rw,nosuid,nodev,noexec,relatime,devices) cgroup on /sys/fs/cgroup/freezer type cgroup (rw,nosuid,nodev,noexec,relatime,freezer) cgroup on /sys/fs/cgroup/net_cls type cgroup (rw,nosuid,nodev,noexec,relatime,net_cls) cgroup on /sys/fs/cgroup/blkio type cgroup (rw,nosuid,nodev,noexec,relatime,blkio) mqueue on /dev/mqueue type mqueue (rw,relatime) debugfs on /sys/kernel/debug type debugfs (rw,relatime) hugetlbfs on /dev/hugepages type hugetlbfs (rw,relatime) configfs on /sys/kernel/config type configfs (rw,relatime) systemd-1 on /proc/sys/fs/binfmt_misc type autofs (rw,relatime,fd=36,pgrp=1,timeout=300,minproto=5,maxproto=5,direct) tmpfs on /tmp type tmpfs (rw) tmpfs on /etc/pacman.d/gnupg type tmpfs (rw,relatime,mode=755) As we can see, the root partition is from the device /dev/mapper/arch_root-image and my problem is that the live system recognizes it as a 3.9GB drive $ df -h Filesystem Size Used Avail Use% Mounted on /dev/mapper/arch_root-image 3.9G 1.9G 2.1G 48% / dev 494M 0 494M 0% /dev run 503M 23M 481M 5% /run /dev/sda1 962M 590M 324M 65% /run/archiso/bootmnt cowspace 755M 32M 723M 5% /run/archiso/cowspace /dev/loop0 520M 520M 0 100% /run/archiso/sfs/root-image tmpfs 503M 132K 503M 1% /dev/shm tmpfs 503M 0 503M 0% /sys/fs/cgroup tmpfs 503M 360K 503M 1% /tmp tmpfs 503M 896K 503M 1% /etc/pacman.d/gnupg My question is how is this size controled? I suspect this is related to the content of the aitab file which is part of the Bridge iso image: $ cat aitab # <img> <mnt> <arch> <sfs_comp> <fs_type> <fs_size> root-image / i686 xz ext4 50% I have read https://wiki.archlinux.org/index.php/archiso#aitab but found no clue

  • How to install VMware tools for Ubuntu 11.04 hosted on VMware ESXi?

    - by Dmitri Toubelis
    I'm running Vmware ESX 4.1 and I have a development VM that I recently upgraded from Ubuntu 10.04 to 11.04. Then I tried to re-install VMware Tools and some of the modules gave me an error and would not compile. As a result I'm having problems with backing up this virtual machine now and I suspect VMware tools is the reason. I installed latest patches for VMware host, that included an update to VMware Tools (v8.3.7 build-381511) but I'm still getting the same error. The error I'm getting is like this: ... /tmp/vmware-root/modules/vmhgfs-only/super.c:73:4: error: unknown field \u2018clear_inode\u2019 specified in initializer make[2]: *** [/tmp/vmware-root/modules/vmhgfs-only/super.o] Error 1 make[1]: *** [_module_/tmp/vmware-root/modules/vmhgfs-only] Error 2 make[1]: Leaving directory `/usr/src/linux-headers-2.6.38-8-generic' make: *** [vmhgfs.ko] Error 2 make: Leaving directory `/tmp/vmware-root/modules/vmhgfs-only' and also this: /tmp/vmware-root/modules/vmci-only/vmci_drv.c:91:4: error: unknown field \u2018ioctl\u2019 specified in initializer /tmp/vmware-root/modules/vmci-only/vmci_drv.c:91:4: warning: initialization from incompatible pointer type /tmp/vmware-root/modules/vmci-only/vmci_drv.c: In function \u2018vmci_init\u2019: /tmp/vmware-root/modules/vmci-only/vmci_drv.c:151:4: error: implicit declaration of function \u2018init_MUTEX\u2019 make[2]: *** [/tmp/vmware-root/modules/vmci-only/vmci_drv.o] Error 1 make[1]: *** [_module_/tmp/vmware-root/modules/vmci-only] Error 2 make[1]: Leaving directory `/usr/src/linux-headers-2.6.38-8-generic' make: *** [vmci.ko] Error 2 make: Leaving directory `/tmp/vmware-root/modules/vmci-only' Any ideas?

[email protected]'s' State = sftp, Before = '' Invalid SSH password Running 'sftp [email protected]' failed (attempt #1) I can ssh into [email protected] fine, and in fact have the ip in known_hosts before I tried any of this. serer 1 (from which I'm running the duplicity command) is Linode's default Ubuntu 8 setup with only a handful of programs installed via apt-get. server 2 (represented by x.x.x.x) is literally only Linode's default Ubuntu 8 setup I previously tried using SystemImager -- would that have changed settings in a destructive way? (I have removed and rebooted since then) Isn't Duplicity supposed to prompt for password? Am I using it wrong? are there common mistakes/dependencies I need to know about? Is there any way that x.x.x.x could be setup that could make this not work (I used Linode's default Ubuntu 8 setup and barely )?

  • How to stop Cron from sending messages about errors

  • Identifying Httpd error log in Fedora 16

    - by Cerin
    How do you find the cause of httpd errors in Fedora 16? The new systemctl command in Fedora 16 seems to horribly obscure any useful logging info. [root@host ~]# systemctl start httpd.service Job failed. See system logs and 'systemctl status' for details. [root@host ~]# systemctl status httpd.service httpd.service - The Apache HTTP Server (prefork MPM) Loaded: loaded (/lib/systemd/system/httpd.service; enabled) Active: failed since Thu, 21 Jun 2012 16:26:56 -0400; 1min 23s ago Process: 2119 ExecStop=/usr/sbin/httpd $OPTIONS -k stop (code=exited, status=0/SUCCESS) Process: 2215 ExecStart=/usr/sbin/httpd $OPTIONS -k start (code=exited, status=1/FAILURE) Main PID: 1062 (code=exited, status=0/SUCCESS) CGroup: name=systemd:/system/httpd.service So the first command fails...and it tells me to run another command...which simply tells me that the command returned an error code. Where's the actual error? Even more frustrating is nothing seems to have been written to the logs: [root@host ~]# ls -lah /var/log/httpd/ total 8.0K drwx------. 2 root root 4.0K Jun 21 16:19 . drwxr-xr-x. 21 root root 4.0K Jun 20 16:33 .. -rw-r----- 1 root root 0 Jun 21 16:19 modsec_audit.log -rw-r----- 1 root root 0 Jun 21 16:19 modsec_debug.log

  • How to allow writing to a mounted NFS partition

    - by Cerin
    How do you allow a specific user permission to write to an NFS partition? I've mounted an NFS share on my localhost (a Fedora install), and I can read and write as root, but I'm unable to write as the apache user, even though all the files and directories in the share on my localhost and remote host are owned by apache. For example, I've mounted it via this line in my /etc/fstab: remotehost:/data/media /data/media nfs _netdev,soft,intr,rw,bg 0 0 And both locations are owned by apache: [root@remotehost ~]# ls -la /data total 24 drwxr-xr-x. 6 root root 4096 Jan 6 2011 . dr-xr-xr-x. 28 root root 4096 Oct 31 2011 .. drwxr-xr-x 4 apache apache 4096 Jan 14 2011 media [root@localhost ~]# ls -la /data total 16 drwxr-xr-x 4 apache apache 4096 Dec 7 2011 . dr-xr-xr-x. 27 root root 4096 Jun 11 15:51 .. drwxrwxrwx 5 apache apache 4096 Jan 31 2011 media However, when I try and write as the apache user, I get a "Permission denied" error. [root@localhost ~]# sudo -u apache touch /data/media/test.txt' touch: cannot touch `/data/media/test.txt': Permission denied But of course it works fine as root. What am I doing wrong?

  • Audit file removal (auditctl)

    - by user1513039
    For some reason, some script or program is removing a pid file for the service on the linux server (centos5.4 / 2.6.18-308.4.1.el5xen). I suspect a faulty cron script, but manual investigation did not lead me to it. And i still want to track it down. Have been using auditctl rule: auditctl -w /var/run/some_service.pid -p w Which helped me to see something, but not quite exactly what i wanted: type=PATH msg=audit(11/12/2013 09:07:43.199:432577) : item=1 name=/var/run/some_service.pid inode=12419227 dev=fd:00 mode=file,644 ouid=root ogid=root rdev=00:00 type=SYSCALL msg=audit(11/12/2013 09:07:43.199:432577) : arch=x86_64 syscall=unlink success=yes exit=0 a0=7fff7dd46dd0 a1=1 a2=2 a3=127feb90 items=2 ppid=3454 pid=6227 auid=root uid=root gid=root euid=root suid=root fsuid=root egid=root sgid=root fsgid=root tty=pts0 ses=38138 comm=rm exe=/bin/rm key=(null) Problem here is that i see ppid of the script that removed the file, but at the analysis time the (p)pids are already invalid as probably scripts/programs have been shutdown. Imagine a cron script deleting the file. So i need some way to expand/add audit rule(s) to be able to trace the parents of the /bin/rm at the time of removal. I have been thinking to add some rule to monitor all process creation, something like: auditctl -a task,always But this happen to be very resource intensive. So i need help or advice how to combine these rules, or how to expand any of the rules to help track the script/program. Thanks.

  • Using FiddlerCore to capture HTTP Requests with .NET

    - by Rick Strahl
    Over the last few weeks I’ve been working on my Web load testing utility West Wind WebSurge. One of the key components of a load testing tool is the ability to capture URLs effectively so that you can play them back later under load. One of the options in WebSurge for capturing URLs is to use its built-in capture tool which acts as an HTTP proxy to capture any HTTP and HTTPS traffic from most Windows HTTP clients, including Web Browsers as well as standalone Windows applications and services. To make this happen, I used Eric Lawrence’s awesome FiddlerCore library, which provides most of the functionality of his desktop Fiddler application, all rolled into an easy to use library that you can plug into your own applications. FiddlerCore makes it almost too easy to capture HTTP content! For WebSurge I needed to capture all HTTP traffic in order to capture the full HTTP request – URL, headers and any content posted by the client. The result of what I ended up creating is this semi-generic capture form: In this post I’m going to demonstrate how easy it is to use FiddlerCore to build this HTTP Capture Form.  If you want to jump right in here are the links to get Telerik’s Fiddler Core and the code for the demo provided here. FiddlerCore Download FiddlerCore on NuGet Show me the Code (WebSurge Integration code from GitHub) Download the WinForms Sample Form West Wind Web Surge (example implementation in live app) Note that FiddlerCore is bound by a license for commercial usage – see license.txt in the FiddlerCore distribution for details. Integrating FiddlerCore FiddlerCore is a library that simply plugs into your application. You can download it from the Telerik site and manually add the assemblies to your project, or you can simply install the NuGet package via:       PM> Install-Package FiddlerCore The library consists of the FiddlerCore.dll as well as a couple of support libraries (CertMaker.dll and BCMakeCert.dll) that are used for installing SSL certificates. I’ll have more on SSL captures and certificate installation later in this post. But first let’s see how easy it is to use FiddlerCore to capture HTTP content by looking at how to build the above capture form. Capturing HTTP Content Once the library is installed it’s super easy to hook up Fiddler functionality. Fiddler includes a number of static class methods on the FiddlerApplication object that can be called to hook up callback events as well as actual start monitoring HTTP URLs. In the following code directly lifted from WebSurge, I configure a few filter options on Form level object, from the user inputs shown on the form by assigning it to a capture options object. In the live application these settings are persisted configuration values, but in the demo they are one time values initialized and set on the form. Once these options are set, I hook up the AfterSessionComplete event to capture every URL that passes through the proxy after the request is completed and start up the Proxy service:void Start() { if (tbIgnoreResources.Checked) CaptureConfiguration.IgnoreResources = true; else CaptureConfiguration.IgnoreResources = false; string strProcId = txtProcessId.Text; if (strProcId.Contains('-')) strProcId = strProcId.Substring(strProcId.IndexOf('-') + 1).Trim(); strProcId = strProcId.Trim(); int procId = 0; if (!string.IsNullOrEmpty(strProcId)) { if (!int.TryParse(strProcId, out procId)) procId = 0; } CaptureConfiguration.ProcessId = procId; CaptureConfiguration.CaptureDomain = txtCaptureDomain.Text; FiddlerApplication.AfterSessionComplete += FiddlerApplication_AfterSessionComplete; FiddlerApplication.Startup(8888, true, true, true); } The key lines for FiddlerCore are just the last two lines of code that include the event hookup code as well as the Startup() method call. Here I only hook up to the AfterSessionComplete event but there are a number of other events that hook various stages of the HTTP request cycle you can also hook into. Other events include BeforeRequest, BeforeResponse, RequestHeadersAvailable, ResponseHeadersAvailable and so on. In my case I want to capture the request data and I actually have several options to capture this data. AfterSessionComplete is the last event that fires in the request sequence and it’s the most common choice to capture all request and response data. I could have used several other events, but AfterSessionComplete is one place where you can look both at the request and response data, so this will be the most common place to hook into if you’re capturing content. The implementation of AfterSessionComplete is responsible for capturing all HTTP request headers and it looks something like this:private void FiddlerApplication_AfterSessionComplete(Session sess) { // Ignore HTTPS connect requests if (sess.RequestMethod == "CONNECT") return; if (CaptureConfiguration.ProcessId > 0) { if (sess.LocalProcessID != 0 && sess.LocalProcessID != CaptureConfiguration.ProcessId) return; } if (!string.IsNullOrEmpty(CaptureConfiguration.CaptureDomain)) { if (sess.hostname.ToLower() != CaptureConfiguration.CaptureDomain.Trim().ToLower()) return; } if (CaptureConfiguration.IgnoreResources) { string url = sess.fullUrl.ToLower(); var extensions = CaptureConfiguration.ExtensionFilterExclusions; foreach (var ext in extensions) { if (url.Contains(ext)) return; } var filters = CaptureConfiguration.UrlFilterExclusions; foreach (var urlFilter in filters) { if (url.Contains(urlFilter)) return; } } if (sess == null || sess.oRequest == null || sess.oRequest.headers == null) return; string headers = sess.oRequest.headers.ToString(); var reqBody = sess.GetRequestBodyAsString(); // if you wanted to capture the response //string respHeaders = session.oResponse.headers.ToString(); //var respBody = session.GetResponseBodyAsString(); // replace the HTTP line to inject full URL string firstLine = sess.RequestMethod + " " + sess.fullUrl + " " + sess.oRequest.headers.HTTPVersion; int at = headers.IndexOf("\r\n"); if (at < 0) return; headers = firstLine + "\r\n" + headers.Substring(at + 1); string output = headers + "\r\n" + (!string.IsNullOrEmpty(reqBody) ? reqBody + "\r\n" : string.Empty) + Separator + "\r\n\r\n"; BeginInvoke(new Action<string>((text) => { txtCapture.AppendText(text); UpdateButtonStatus(); }), output); } The code starts by filtering out some requests based on the CaptureOptions I set before the capture is started. These options/filters are applied when requests actually come in. This is very useful to help narrow down the requests that are captured for playback based on options the user picked. I find it useful to limit requests to a certain domain for captures, as well as filtering out some request types like static resources – images, css, scripts etc. This is of course optional, but I think it’s a common scenario and WebSurge makes good use of this feature. AfterSessionComplete like other FiddlerCore events, provides a Session object parameter which contains all the request and response details. There are oRequest and oResponse objects to hold their respective data. In my case I’m interested in the raw request headers and body only, as you can see in the commented code you can also retrieve the response headers and body. Here the code captures the request headers and body and simply appends the output to the textbox on the screen. Note that the Fiddler events are asynchronous, so in order to display the content in the UI they have to be marshaled back the UI thread with BeginInvoke, which here simply takes the generated headers and appends it to the existing textbox test on the form. As each request is processed, the headers are captured and appended to the bottom of the textbox resulting in a Session HTTP capture in the format that Web Surge internally supports, which is basically raw request headers with a customized 1st HTTP Header line that includes the full URL rather than a server relative URL. When the capture is done the user can either copy the raw HTTP session to the clipboard, or directly save it to file. This raw capture format is the same format WebSurge and also Fiddler use to import/export request data. While this code is application specific, it demonstrates the kind of logic that you can easily apply to the request capture process, which is one of the reasonsof why FiddlerCore is so powerful. You get to choose what content you want to look up as part of your own application logic and you can then decide how to capture or use that data as part of your application. The actual captured data in this case is only a string. The user can edit the data by hand or in the the case of WebSurge, save it to disk and automatically open the captured session as a new load test. Stopping the FiddlerCore Proxy Finally to stop capturing requests you simply disconnect the event handler and call the FiddlerApplication.ShutDown() method:void Stop() { FiddlerApplication.AfterSessionComplete -= FiddlerApplication_AfterSessionComplete; if (FiddlerApplication.IsStarted()) FiddlerApplication.Shutdown(); } As you can see, adding HTTP capture functionality to an application is very straight forward. FiddlerCore offers tons of features I’m not even touching on here – I suspect basic captures are the most common scenario, but a lot of different things can be done with FiddlerCore’s simple API interface. Sky’s the limit! The source code for this sample capture form (WinForms) is provided as part of this article. Adding Fiddler Certificates with FiddlerCore One of the sticking points in West Wind WebSurge has been that if you wanted to capture HTTPS/SSL traffic, you needed to have the full version of Fiddler and have HTTPS decryption enabled. Essentially you had to use Fiddler to configure HTTPS decryption and the associated installation of the Fiddler local client certificate that is used for local decryption of incoming SSL traffic. While this works just fine, requiring to have Fiddler installed and then using a separate application to configure the SSL functionality isn’t ideal. Fortunately FiddlerCore actually includes the tools to register the Fiddler Certificate directly using FiddlerCore. Why does Fiddler need a Certificate in the first Place? Fiddler and FiddlerCore are essentially HTTP proxies which means they inject themselves into the HTTP conversation by re-routing HTTP traffic to a special HTTP port (8888 by default for Fiddler) and then forward the HTTP data to the original client. Fiddler injects itself as the system proxy in using the WinInet Windows settings  which are the same settings that Internet Explorer uses and that are configured in the Windows and Internet Explorer Internet Settings dialog. Most HTTP clients running on Windows pick up and apply these system level Proxy settings before establishing new HTTP connections and that’s why most clients automatically work once Fiddler – or FiddlerCore/WebSurge are running. For plain HTTP requests this just works – Fiddler intercepts the HTTP requests on the proxy port and then forwards them to the original port (80 for HTTP and 443 for SSL typically but it could be any port). For SSL however, this is not quite as simple – Fiddler can easily act as an HTTPS/SSL client to capture inbound requests from the server, but when it forwards the request to the client it has to also act as an SSL server and provide a certificate that the client trusts. This won’t be the original certificate from the remote site, but rather a custom local certificate that effectively simulates an SSL connection between the proxy and the client. If there is no custom certificate configured for Fiddler the SSL request fails with a certificate validation error. The key for this to work is that a custom certificate has to be installed that the HTTPS client trusts on the local machine. For a much more detailed description of the process you can check out Eric Lawrence’s blog post on Certificates. If you’re using the desktop version of Fiddler you can install a local certificate into the Windows certificate store. Fiddler proper does this from the Options menu: This operation does several things: It installs the Fiddler Root Certificate It sets trust to this Root Certificate A new client certificate is generated for each HTTPS site monitored Certificate Installation with FiddlerCore You can also provide this same functionality using FiddlerCore which includes a CertMaker class. Using CertMaker is straight forward to use and it provides an easy way to create some simple helpers that can install and uninstall a Fiddler Root certificate:public static bool InstallCertificate() { if (!CertMaker.rootCertExists()) { if (!CertMaker.createRootCert()) return false; if (!CertMaker.trustRootCert()) return false; } return true; } public static bool UninstallCertificate() { if (CertMaker.rootCertExists()) { if (!CertMaker.removeFiddlerGeneratedCerts(true)) return false; } return true; } InstallCertificate() works by first checking whether the root certificate is already installed and if it isn’t goes ahead and creates a new one. The process of creating the certificate is a two step process – first the actual certificate is created and then it’s moved into the certificate store to become trusted. I’m not sure why you’d ever split these operations up since a cert created without trust isn’t going to be of much value, but there are two distinct steps. When you trigger the trustRootCert() method, a message box will pop up on the desktop that lets you know that you’re about to trust a local private certificate. This is a security feature to ensure that you really want to trust the Fiddler root since you are essentially installing a man in the middle certificate. It’s quite safe to use this generated root certificate, because it’s been specifically generated for your machine and thus is not usable from external sources, the only way to use this certificate in a trusted way is from the local machine. IOW, unless somebody has physical access to your machine, there’s no useful way to hijack this certificate and use it for nefarious purposes (see Eric’s post for more details). Once the Root certificate has been installed, FiddlerCore/Fiddler create new certificates for each site that is connected to with HTTPS. You can end up with quite a few temporary certificates in your certificate store. To uninstall you can either use Fiddler and simply uncheck the Decrypt HTTPS traffic option followed by the remove Fiddler certificates button, or you can use FiddlerCore’s CertMaker.removeFiddlerGeneratedCerts() which removes the root cert and any of the intermediary certificates Fiddler created. Keep in mind that when you uninstall you uninstall the certificate for both FiddlerCore and Fiddler, so use UninstallCertificate() with care and realize that you might affect the Fiddler application’s operation by doing so as well. When to check for an installed Certificate Note that the check to see if the root certificate exists is pretty fast, while the actual process of installing the certificate is a relatively slow operation that even on a fast machine takes a few seconds. Further the trust operation pops up a message box so you probably don’t want to install the certificate repeatedly. Since the check for the root certificate is fast, you can easily put a call to InstallCertificate() in any capture startup code – in which case the certificate installation only triggers when a certificate is in fact not installed. Personally I like to make certificate installation explicit – just like Fiddler does, so in WebSurge I use a small drop down option on the menu to install or uninstall the SSL certificate:   This code calls the InstallCertificate and UnInstallCertificate functions respectively – the experience with this is similar to what you get in Fiddler with the extra dialog box popping up to prompt confirmation for installation of the root certificate. Once the cert is installed you can then capture SSL requests. There’s a gotcha however… Gotcha: FiddlerCore Certificates don’t stick by Default When I originally tried to use the Fiddler certificate installation I ran into an odd problem. I was able to install the certificate and immediately after installation was able to capture HTTPS requests. Then I would exit the application and come back in and try the same HTTPS capture again and it would fail due to a missing certificate. CertMaker.rootCertExists() would return false after every restart and if re-installed the certificate a new certificate would get added to the certificate store resulting in a bunch of duplicated root certificates with different keys. What the heck? CertMaker and BcMakeCert create non-sticky CertificatesI turns out that FiddlerCore by default uses different components from what the full version of Fiddler uses. Fiddler uses a Windows utility called MakeCert.exe to create the Fiddler Root certificate. FiddlerCore however installs the CertMaker.dll and BCMakeCert.dll assemblies, which use a different crypto library (Bouncy Castle) for certificate creation than MakeCert.exe which uses the Windows Crypto API. The assemblies provide support for non-windows operation for Fiddler under Mono, as well as support for some non-Windows certificate platforms like iOS and Android for decryption. The bottom line is that the FiddlerCore provided bouncy castle assemblies are not sticky by default as the certificates created with them are not cached as they are in Fiddler proper. To get certificates to ‘stick’ you have to explicitly cache the certificates in Fiddler’s internal preferences. A cache aware version of InstallCertificate looks something like this:public static bool InstallCertificate() { if (!CertMaker.rootCertExists()) { if (!CertMaker.createRootCert()) return false; if (!CertMaker.trustRootCert()) return false; App.Configuration.UrlCapture.Cert = FiddlerApplication.Prefs.GetStringPref("fiddler.certmaker.bc.cert", null); App.Configuration.UrlCapture.Key = FiddlerApplication.Prefs.GetStringPref("fiddler.certmaker.bc.key", null); } return true; } public static bool UninstallCertificate() { if (CertMaker.rootCertExists()) { if (!CertMaker.removeFiddlerGeneratedCerts(true)) return false; } App.Configuration.UrlCapture.Cert = null; App.Configuration.UrlCapture.Key = null; return true; } In this code I store the Fiddler cert and private key in an application configuration settings that’s stored with the application settings (App.Configuration.UrlCapture object). These settings automatically persist when WebSurge is shut down. The values are read out of Fiddler’s internal preferences store which is set after a new certificate has been created. Likewise I clear out the configuration settings when the certificate is uninstalled. In order for these setting to be used you have to also load the configuration settings into the Fiddler preferences *before* a call to rootCertExists() is made. I do this in the capture form’s constructor:public FiddlerCapture(StressTestForm form) { InitializeComponent(); CaptureConfiguration = App.Configuration.UrlCapture; MainForm = form; if (!string.IsNullOrEmpty(App.Configuration.UrlCapture.Cert)) { FiddlerApplication.Prefs.SetStringPref("fiddler.certmaker.bc.key", App.Configuration.UrlCapture.Key); FiddlerApplication.Prefs.SetStringPref("fiddler.certmaker.bc.cert", App.Configuration.UrlCapture.Cert); }} This is kind of a drag to do and not documented anywhere that I could find, so hopefully this will save you some grief if you want to work with the stock certificate logic that installs with FiddlerCore. MakeCert provides sticky Certificates and the same functionality as Fiddler But there’s actually an easier way. If you want to skip the above Fiddler preference configuration code in your application you can choose to distribute MakeCert.exe instead of certmaker.dll and bcmakecert.dll. When you use MakeCert.exe, the certificates settings are stored in Windows so they are available without any custom configuration inside of your application. It’s easier to integrate and as long as you run on Windows and you don’t need to support iOS or Android devices is simply easier to deal with. To integrate into your project, you can remove the reference to CertMaker.dll (and the BcMakeCert.dll assembly) from your project. Instead copy MakeCert.exe into your output folder. To make sure MakeCert.exe gets pushed out, include MakeCert.exe in your project and set the Build Action to None, and Copy to Output Directory to Copy if newer. Note that the CertMaker.dll reference in the project has been removed and on disk the files for Certmaker.dll, as well as the BCMakeCert.dll files on disk. Keep in mind that these DLLs are resources of the FiddlerCore NuGet package, so updating the package may end up pushing those files back into your project. Once MakeCert.exe is distributed FiddlerCore checks for it first before using the assemblies so as long as MakeCert.exe exists it’ll be used for certificate creation (at least on Windows). Summary FiddlerCore is a pretty sweet tool, and it’s absolutely awesome that we get to plug in most of the functionality of Fiddler right into our own applications. A few years back I tried to build this sort of functionality myself for an app and ended up giving up because it’s a big job to get HTTP right – especially if you need to support SSL. FiddlerCore now provides that functionality as a turnkey solution that can be plugged into your own apps easily. The only downside is FiddlerCore’s documentation for more advanced features like certificate installation which is pretty sketchy. While for the most part FiddlerCore’s feature set is easy to work with without any documentation, advanced features are often not intuitive to gleam by just using Intellisense or the FiddlerCore help file reference (which is not terribly useful). While Eric Lawrence is very responsive on his forum and on Twitter, there simply isn’t much useful documentation on Fiddler/FiddlerCore available online. If you run into trouble the forum is probably the first place to look and then ask a question if you can’t find the answer. The best documentation you can find is Eric’s Fiddler Book which covers a ton of functionality of Fiddler and FiddlerCore. The book is a great reference to Fiddler’s feature set as well as providing great insights into the HTTP protocol. The second half of the book that gets into the innards of HTTP is an excellent read for anybody who wants to know more about some of the more arcane aspects and special behaviors of HTTP – it’s well worth the read. While the book has tons of information in a very readable format, it’s unfortunately not a great reference as it’s hard to find things in the book and because it’s not available online you can’t electronically search for the great content in it. But it’s hard to complain about any of this given the obvious effort and love that’s gone into this awesome product for all of these years. A mighty big thanks to Eric Lawrence  for having created this useful tool that so many of us use all the time, and also to Telerik for picking up Fiddler/FiddlerCore and providing Eric the resources to support and improve this wonderful tool full time and keeping it free for all.

  • In an iPad SplitView, how do I add a Date Picker control to the Root View?

    - by Dr Dork
    I'm diving into iPhone OS development on the iPad and one of the things I'm playing with is the SplitView template. The template provides a window with a UISplitView view, containing the Root View (on the left of the window) and the Detail View (on the right of the window). The Root View is a subclass of a TableView. Rather than having the entire Root View consist of a TableView, I'd like it to contain a DatePicker view along with the TableView under it. When I go into IB and try and drop a DatePicker into the Root View, it won't let me. It will only let me add a DatePicker view to the Detail View. Why wont IB let me drop a DatePicker view into the Root View? How can I add a DatePicker to the RootView in addition to the TableView? I'm still learning this new platform, so I apologize if these questions are absurd in any way. Thanks so much in advance for your help, I'm going to continue researching these questions right now.

  • Git Subtree. Why can't I branch from a subtree rather than the root?

    - by dugla
    I am struggling trying to make sense of using the Git subtree strategy. My intent was to pull some disparate repos together into a little family of toy repos under an umbrella repo. I'm using the subtree strategy detailed here: http://help.github.com/subtree-merge I am pulling my hair out trying to convince Git that I want to create a branch from one of these subtrees NOT from the root. When I cd into a subtree, create the branch, and then cd back to the root, running git branch from the root clearly indicates the branch was created at the root. Sigh. I love git/github but it is maddening getting this seemingly routine task to work properly. Could someone please enlighten me?

  • Short hand for number of tags having lengthier [and almost same] Xpath

    - by infant programmer
    For example : this is an xslt <xsl:template match="/root/sub-root/parent/child/grand_child/dummy1/dummy2/dummy3/dummy4/node_1 |/root/sub-root/parent/child/grand_child/dummy1/dummy2/dummy3/dummy4/node_2 |/root/sub-root/parent/child/grand_child/dummy1/dummy2/dummy3/dummy4/node_3 . . |/root/sub-root/parent/child/grand_child/dummy1/dummy2/dummy3/dummy4/node_N"/> In the above code can I use the XPath /root/sub-root/parent/child/grand_child/dummy1/dummy2/dummy3/dummy4 only once [use the braces or whatever] and reduce the bulkiness of the code? As you can see, all the nodes are siblings of each-other, so except their name their Xpath is same. Is there any short-hand property ? Does XSLT 1.0 (or Xpath1.0) allows it?
