  • after dup2, stream still contains old contents?

    - by BobTurbo
    so if I do: dup2(0, backup); // backup stdin dup2(somefile, 0); // somefile has four lines of content fgets(...stdin); // consume one line fgets(....stdin); // consume two lines dup2(backup, 0); // switch stdin back to keyboard I am finding at this point.. stdin still contains the two lines I haven't consumed. Why is that? Because there is just one buffer no matter how many times you redirect? How do I get rid of the two lines left but still remember where I was in the somefile stream when I want to go back to it?

  • Perl, redirect stdout to file

    - by Mike
    I'm looking for an example of redirecting stdout to a file using Perl. I'm doing a fairly straightforward fork/exec tool, and I want to redirect the child's output to a file instead of the parents stdout. Is there an equivilant of dup2() I should use? I can't seem to find it

  • Redirecting http to https for a directory, via .htaccess, using mod_alias only

    - by Belinda
    I have the common problem of wanting to redirect requests for a certain restricted access directory from http to https, so that users' login credentials are sent in a secure way. However, I do not have mod_rewrite enabled on my server. I only have mod_alias. This means I have to use the RedirectMatch command. I can't use the usual solutions that use RewriteCond and RewriteRule. (A note on the politics: I am a small-fry subsite maintainer in a very large organisation, so the server admins are unlikely to be willing to change the server config for me!) The following line works, but forms an infinite loop (because the rewritten URL is still caught by the initial regular expression): RedirectMatch permanent ^/intranet(.*)$ https://example.com/intranet$1 One of my internal IT guys has suggested I avoid the infinite loop by moving the files to a new directory with a new name (eg /intranet2/). That seems pretty ugly to me. And people could still accidentally/deliberately revert to an insecure connection by visiting http://example.com/intranet2/ directly. Then I tried this, but it didn't work: RedirectMatch permanent ^http:(.*)/intranet(.*)$ https://example.com/intranet$1 I suspect it didn't work because the first argument must be a file path from the root directory, so it can't start with "http:". So: any better ideas how to do this?

  • IIS redirects to url beginning with "http://http" although syntax in web.config file appears to be alright

    - by user1608920
    Here's what I have so far: <?xml version="1.0" encoding="UTF-8"?> <configuration> <location path="osb"> <system.webServer> <httpRedirect enabled="true" exactDestination="true" destination="http://50.63.54.135/app/osb" httpResponseStatus="Permanent" /> </system.webServer> </location> </configuration> The above redirect works, but it takes me to http://http//50.63.54.135/app/osb instead of just http://50.63.54.135/app/osb This produces an 404 error. I tried to remove "http://" from destination. Same effect. What am I missing ?

  • How to handle redirections with codeigniter?

    - by SinneR
    Hi, im having problems starting a codeigniter project, the problem is that when i do something in a controller and then i want a page to display the result, an example: i have a form to add a item to the database, i get all the data in the controller and save it to database and then i want (if all went well) to redirect to the main page with a success msg, i was doing this with $this->load->view('admin', $data); the problem is that the url keeps saying admin/addItem so everytime the page gets refreshed it adds another item, now i found the: redirect('admin','refresh'); but this only helps me when i dont need to display any msg because this function dont allow to send a $data var. Any ideas? Probably this is really easy to fix but i cant find a way to handle the flow of the application the way i want, any help is apreciated. thanks ;)

  • iptables: allowing incoming for 192.168.1.0/24 allowed incoming for all?

    - by nortally
    The internal side of my ISP router has three devices: ISP router 128.128.43.1 Firewall router 128.128.43.2 Server 128.128.43.3 Behind the Firewall router is a NAT network using 192.168.100.n/24 This question is regarding iptables running on the Server. I wanted to allow access to port 8080 only from the NAT clients behind the Firewall router, so I used this rule -A Firewall-1-INPUT -s 192.168.100.0/24 -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT This worked, but UNEXPECTEDLY ALLOWED GLOBAL ACCESS, which resulted in our JBOSS server getting compromised. I now know that the correct rule is to use the Firewall router's address instead of the internal network, but can anyone explain why the first rule allowed global access? I would have expected it to just fail. Full config, mostly lifted from a RedHat server: *filter :INPUT ACCEPT [0:0] :FORWARD ACCEPT [0:0] :OUTPUT ACCEPT [0:0] :Firewall-1-INPUT - [0:0] -A INPUT -j Firewall-1-INPUT -A FORWARD -j Firewall-1-INPUT -A Firewall-1-INPUT -i lo -j ACCEPT -A Firewall-1-INPUT -p icmp --icmp-type any -j ACCEPT -A Firewall-1-INPUT -m state --state ESTABLISHED,RELATED -j ACCEPT -A Firewall-1-INPUT -m comment --comment "allow ssh from all" -A Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 22 -j ACCEPT -A Firewall-1-INPUT -m comment --comment "allow https from all" -A Firewall-1-INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT -A Firewall-1-INPUT -m comment --comment "allow JBOSS from Firewall" ### THIS RESULTED IN GLOBAL ACCESS TO PORT 8080 ### -A Firewall-1-INPUT -s 192.168.100.0/24 -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPT ### THIS WORKED -A Firewall-1-INPUT -s 128.128.43.2 -m state --state NEW -m tcp -p tcp --dport 8080 -j ACCEPt ### -A Firewall-1-INPUT -j REJECT --reject-with icmp-host-prohibited COMMIT

  • Have an Input/output error when connecting to a server via ssh

    - by Shehzad009
    Hello I seem to be having a problem while connecting to a Ubuntu Server while connecting via ssh. When I login, I get this error. Could not chdir to home directory /home/username: Input/output error It seems like my home folder is corrupt or something. I cannot ls in the home folder directory, and in my usename directory, I can't cd into this. As root I cannot ls in the home directory as well or in any directory in Home. I notice as well when I save in vim or quit, it get this error at the bottom of the page E138: Cannot write viminfo file /home/root/.viminfo! Any ideas?

  • Excel Help: Data Input Help

    - by B-Ballerl
    Everyday I download data from a site that will have rows each filled with individual data for clients. I'm able to input the data into excel as a whole but after that I'm having trouble figuring out how to put it into a chart. For example Web visits time. So say Client 1 stayed for 5 min increasing his total time on the site to 20 min and Client 2 stayed for 0 min keeping his time of 10 min and they were both registered on new years eve, and R1's last login was today and R2's was yesterday. (R for some reason repersents Client, no idea why...). Client 3 hasn't been on since he registered keeping his total at 4 min So my data would look something like this for Today (20110104) R1,20101231,20110104,20 R2,20101231,20110103,10 R3,20101231,20101231,4 And this for the day before (201101030), R1,20101231,20110102,15 R2,20101231,20110103,10 R3,20101231,20101231,4 I get about 200+ client rows each day where even the names of the Client list are changing. Is it possible to import the data each day and fill it in a excel sheet where the Client number is off on the left hand side in a table, and the amount of time (Whole Number ex. 4) each day it spends on the site extend to the right under it's specific date see Picture? I've manage to create a manual sheet but have been unsucessful at getting excel to do any of it for me. Here are two pictures:

  • mount error 5 = Input/output error

    - by alharaka
    I am running out of ideas. After a long period of testing this morning, I cannot seem to get this to work, and I have no idea why. I want to mount a Windows SMB/CIFS share with a Debian 5.0.4 VM, and it is not cooperating. This the command I am using. debianvm:/home/me# whoami root debianvm:/home/me# smbclient --version Version 3.2.5 debianvm:/home/me# mount -t cifs //hostname.domain.tld/share /mnt/hostname.domain.tld/share --verbose -o user=SUBADDOMAIN.ADDOMAIN.DOMAIN.TLD/username mount.cifs kernel mount options: unc=//hostname.domain.tld\share,ip=10.212.15.53,domain=SUBADDOMAIN.ADDOMAIN.DOMAIN.TLD,ver=1,rw,user=username,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,,pass=*********mount error 5 = Input/output error Refer to the mount.cifs(8) manual page (e.g.man mount.cifs) debianvm:/home/me# The word on the nets has not been very specific, and unfortunately it is almost always environment-specific. I receive no authentication errors. I have tried mount -t smbfs and mount -t cifs, along with smbmount and such. I get the same error before. I doubt it is a problem with DNS resolution, because logging shows the correct IP address. dmesg | tail -f no longer shows authentication errors when I format the domain and username accordingly. I have played a little with iocharset=utf8, file_mode, and dir_mode as described here. That did not help either. I have also tried ntlm and ntlmv2 assuming it might be a minimum auth method problem, but not forcing sec=ntlmv2 it can still authenticate without errors anymore. smbclient -L hostname.domain.tld -W SUBADDOMAIN.ADDOMAIN.DOMAIN.TLD -U username correctly lists all the shares and shows it as the following. Domain=[SUBADDOMAIN] OS=[Windows 5.0] Server=[Windows 2000 LAN Manager] Sharename Type Comment --------- ---- ------- IPC$ IPC Remote IPC ETC$ Disk Remote Administration C$ Disk Remote Administration Share Disk Connection to hostname.domain.tld failed (Error NT_STATUS_CONNECTION_REFUSED) NetBIOS over TCP disabled -- no workgroup available I find the last line intriguing/alarming. Does anyone have any pointers!? Maybe I misread the effin manual.

  • Bonnie does not provide speed for Sequential Input / Block

    - by Lqp1
    I'm using ProxmoxVE and I would like to run some benchmarks regarding performances of this product. One of these benchmarks is bonnie++ ; it runs very well in a VM (qemu-kvm) but when I run it in a conainer (openVZ), it does not provide me reading speed (only writing). I don't understand why... Does anyone know what's happenning ? VMs ans Containers are Debian 7.4. Here's the output of bonnie in the container: root@ct2:/# bonnie++ -u root Using uid:0, gid:0.

  • Problems forwarding port 3306 on iptables with CentOS

    Im trying to add a forward to the mysql server at 200.58.126.52 to allow the access from 200.58.125.39, and Im using the following rules (its my whole iptables of the VPS of my hosting).

  • Input/output error reading USB backup drive on CentOS 6.4

    - by Kev
    I'm suddenly seeing some strange behaviour on our USB backup drive that doesn't make sense to me: (2013-10-21 14:58:23 [root@newdc /]$ cd /mnt/backup/ (2013-10-21 14:59:03 [root@newdc backup]$ ls -la ls: reading directory .: Input/output error total 0 (2013-10-21 14:59:05 [root@newdc backup]$ df -h /mnt/backup Filesystem Size Used Avail Use% Mounted on /dev/sda1 917G 843G 28G 97% /mnt/backup How is it possible for the OS to know how much is in use, but I can't ls any of it as root? Or more to the point, what problem does this indicate? /var/log/messages said this: Oct 21 14:57:54 g5 kernel: EXT4-fs error (device sda1): ext4_journal_start_sb: Detected aborted journal Oct 21 14:57:54 g5 kernel: EXT4-fs (sda1): Remounting filesystem read-only But...read-only is something different than 'throw an io error'... After unmounting to try fsck on it, I had someone on-site look at it, and the drive was not spun up, and had a slow-flashing light, which I believe means it was in a power-suspend mode. So I had them unplug and replug the USB cable, and now (before remounting) it says: fsck from util-linux-ng 2.17.2 e2fsck 1.41.12 (17-May-2010) /dev/sda1: clean, 2805106/61046784 files, 181934167/244182016 blocks I then mount it and now ls works and df reports: Filesystem Size Used Avail Use% Mounted on /dev/sda1 917G 680G 191G 79% /mnt/backup What would cause it to go into such a state without being asked to? Why all the weird behaviour, and now it appears to not be corrupt?

  • Trouble with Remote Desktop pulling through printers. Drive Redirection works, and the ports created but not the printers

    - by Windex
    I've run out of things to look into. All the support documents have been gone through and still provide no resolution. I've checked the service permissions, (sc sdshow spooler) they all match up with other systems and what is output on the support documents. I'm nearly positive that the issue can't be permissions anyway as the software requires all users to be an administrator, so all users are a local administrator. (I haven't looked into why yet but its on the list, I was just recently brought into this team and we've put procedures in place for quick recovery.) We've applied hot fixes relating to RDS and printing, though I'm not sure which ones they were. I've combed through group policy and no where is printer redirection disabled. It's setup with all default values regarding the use and redirection of printers and a quick install of W2k8 R2 shows that it works by default. This dev install was joined to the same domain, placed in the same OU, shows the same policies applied, etc, etc, etc, The server generates all the correct redirected ports but no printers are created. It will also redirect drives without issue, this would seem to rule out the usermode service that handles redirects being broken. No events are logged related to any of the events and there are no events from the TerminalServices-Printer source. There were local printers setup. I didn't think it would mattter but as I was running out of ideas I tried deleting them all with no change. The TS was configured for the software it will be running before we checked out the redirection of printers so the other team responsible to setting up new servers wants to find a fix instead of reloading a new server. I'm not sure where or what else to look for. Any ideas?

  • Ubuntu 12.04 LXC nat prerouting not working

    I have a running Debian Wheezy setup I copied exactly to an Ubuntu 12.04 ( elementary OS, used as desktop as well ) While the Debian setup runs flawlessly, the Ubuntu version dies on the prerouting to containers ( or so it seems ) In short: lxc works containers work and run connecting to container from host OK ( including mixed ports & services ) connecting to outside world from container is fine What does not work is connecting from another box to the host on a port that should be NATed to a container.

I've even tried different kernels ( server kernel, raring lts kernel, etc ), modprobe everything iptables & nat related, nothing. Any ideas?

  • Validation of WPF User Input using MVVM and Entity Framework 4.0

    - by Emad
    I am building a WPF 4.0 Application using MVVM. The Model is generated using Entity Framework 4.0. I am using Data binding on the WPF to bind the user input to model properties. What is the easiest way to validate user input ? I prefer an approach where I can set the validation rules on the Model rather than on the WPF itself. How can this be done? Any samples are appreciated.

  • Using tslib (touchscreen input) with DirectFB on embedded system (gumstix overo)

    - by emi1faber
    I'm attempting to use tslib with DirectFB on the gumstix Overo. Everything seems to be compiled correctly, as when DirectFB starts up, I get messages saying "Started 'tslib Input' ... DirectFB/Input: tslib touchscreen 0 0.1 (tslib)" etc. However, I haven't been able to find any example code showing how one reads the X-Y coordinates of a touchscreen press. Is there any example code out there to initialize the touchscreen and return the coordinates of a touchscreen press? Thanks in advance, Ben

    - by teepusink
    Hi, I'm trying to modified the way TimePicker works as asked in my question here http://stackoverflow.com/questions/2580216/android-timepicker-minutes-to-15 To be able to do that I need to know if the + and - button was clicked and to disable the input field. So can I target the elements in a TimePicker? (i.e the + and - button and the input field)? Also is there anyway to determine if the + or the - button was clicked? Thanks, Tee
