Im trying to do a remote execution of scripts through SSH in PHP. What im doing:
-Use PHP in conjunction with nagios' check_by_ssh script to execute the script.
-I used
[code]...
-It gives me a 'Host key verification failed' error even though i enabled it to ssh from my server to server01 without password. My Qn: How do i get it to work?
i'am running:
Distributor ID: Ubuntu
Description: Ubuntu 9.10
Release: 9.10
Codename: karmic
kernel: 2.6.31-16-generic
pc and laptop are connected via switch. hard wired and static ip on ubuntu side is a wlan running connected to the internet. on my laptop: i am running:
Distributor ID: SuSE
Description: SuSE Linux 9.0 (i586)
Release: 9.0
Codename: n/a
kernel: 2.4.21-99-default ( year 2004 )
on unbuntu side i use: SSH-2.0-OpenSSH_5.1p1 Debian-6ubuntu2. on suse side i use: SSH-1.99-OpenSSH_3.7.1p2. both sides are using: Protocol 2 and ServerKeyBits 768 and now my problem. i can connect from ubuntu to suse using ssh without a problem. when i try to connect from suse to ubuntu i always get: Host key verification failed and nothing else. no hint about middle man attack or so. no change to answer -> save the new key. the permissions of ~/ssh my both sides are id_rsa.pubcorrect i think ( drwx------) and the permissions of : authorized_key, id_rsa, known_hosts are all - -rw------- 1 ( not linked or so ).
I just installed openssh-server, and all tutorials say it should work out of the box. But it doesn't, it dies with "Host key verification failed."
Here is the log:

I know that there are multiple threads with problems like this, but still i didn't found my answer.
The situation is like this:
I have a local server and a remote server, i did a ssh key swap so i can log on to the remote server with no problems (automatically logging on, no need to enter pass or login).
I've made a script that copies (with SCP) a file FROM the REMOTE server TO the LOCAL server (NOT FROM the LOCAL server to the REMOTE server !!!!), and then i get an error like code...
I have Slack 64 bit installed on my desktop, sshd is running. From my netbook running Ubuntu I can not connect through ssh, I always get 'Host key verification failed' message. I have tried a lot of things, I got to a point where I could not ssh either way. So today I removed and re-installed Openssh on both systems. I made sure I was using the new ssh_config and sshd_config files on both systems. Right now I can ssh from the desktop ( Slack ) to Ubuntu ( netbook ) but not the other way around. I do not get a known_hosts file created on Slack, I do get one on Ubuntu. I don't understand why Openssh server on Slack is not accessible, and why the known_hosts file is not getting created.

I recently reinstalled my workstation from OpenSuse 11.2 to 11.4. After the installation, I found that I could not run zypper anymore. A few things to note first.
- OpenSuse 11.4 x64 - behind corporate firewall (which worked fine with zypper as long as a proxy was configured with previous versions
- used that ZYPP_ARIA=0 variable previously to help). - proxies configured in /etc/sysconfig/proxy. - all other network utilities I normally use (browser, ssh) all work fine. - I have removed all repositories and added them again several times. I have also done "zypper clean" several times not that I would expect that to be better than removing and re-adding the repositories. When I attempt to run "zypper ref" or "zypper in foo" I get the following:

If I manually use wget to grab the package and either run it directly or insert it into the /var/cache/zypp tree (replacing the metalink version zypper complains about) it always works and gives me the right file.....
I am having an issue with HTTPS certification using curl. My curl is configured with OpenSSL. If the certification verification is failed I dont want to terminate the operation, instead I want to continue by just putting a log message. For this I have used OpenSSL SSL_CTX_set_verify() function to set my static C callback function. During HTTPS transaction, my callback is also getting called with first parameter 0 or 1 (depending upon of the certificate verification is success or failure). But even if my certification verification is failure, I want to continue. So I have hard coded to return value as 1 always from my callback function. But still I see the certification error and I don't get the page.
View 1 Replies View RelatedI'm currently running 11.3 and decided I'd try upgrading to 11.4 following the instructions here: SDB:System upgrade - openSUSEUnfortunately, my attempts are defeated at the point of trying to refresh the new repos; I get the following message (for the oss repo, in this case):
Download (curl) error for 'url':
Error code: Connection failed
Error message: Couldn't resolve host 'download.opensuse.org'
With 11.4 replaced by 11.3 in the repo url, it refreshes just fine. The only repository that works when I change 11.3 to 11.4 is the Packman repo. I'm not really sure why the connection fails for 11.4 but not 11.3!
Further info: I have an old router with no IPv6 support, but have IPv6 disabled system-wide. I can enter the url for the repositories into firefox and they come up just fine - it's only with zypper/YaST that I get the above error message.I also tried upgrading using the network CD but ran into the same sort of problem. In this case it may be because the CD installer doesn't disable IPv6. (I didn't want to download the DVD at my connection speed, and the KDE live CD is not listed as suitable for upgrade).
I wrote a code for login verification..I got output with GET. But I need output with POST since it is more secure. Any error in my code.
javascript code:
var xml;
function verifyusernamepasswd(pass)
{ //pass is password that will be passed as parameter
xml=new XMLHttpRequest();
var url="http://localhost/loginvalidate.php";
var para="q="+username+"&p="+pass;//username is global
xml.setRequestHeader("Content-type", "application/x-www-form-urlencoded");
xml.setRequestHeader("Content-length", para.length);
xml.setRequestHeader("Connection", "close");
xml.open("POST",url,true);
xml.onreadystatechange=statechanged1;
xml.send(para);
} .....
The verification does not return anything, cos my alert is not displayed at all.
seems im getting this error when i update.I searched the forums for similar errors but i found no solution that worked for me. this is the error>>>>>

I'm working on a old piece of code on linux, after compiling without porblem at the execution I have this response:
src/xproject/xproject: Ok, a color display! :-)
X Error of failed request: BadMatch (invalid parameter attributes)
Major opcode of failed request: 78 (X_CreateColormap)
Serial number of failed request: 7
Current serial number in output stream: 15
looking at the source code I think the problem is related at the depth of my system 24 bit and the depth of this old piece of code 8 bit. Unfortunately also I don't have experience in programming the XVideo and if someone can give me some help in programming the XVideo interface

I'm trying to make an SSH script for my place of employment. This script, I want to go out to the server hostnames we have specified (in another file) and change a users account password. We use Kerberized telnet, so if telnet root hostname fails, I want it to use ssh username hostname and use the old password (specified). If both fail, I want it to ask the user what the port should be and input the port in the ssh command.
But I'm having a issue having it try telnet root hostname and if it fails then, try to ssh in, I have no clue how to have it proceed. Is it an if statement? Here's the telnet failed message: telnet: Unable to connect to remote host: Connection refused

I know that I can go though each rpm one by one and trace each dependency but that will take forever. Is there a way to skip these errors? I know the -nodeps command for rpm but I dont want to screw something up but running all of these rpms on -nodeps
