Ubuntu Networking :: Host Key Verification Failed?

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."

General :: Host Key Verification Failed / Resolve This?

Mar 29, 2011

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...

Slackware :: Can't Ssh Into Slack 13.37 'Host Key Verification Failed'

Jul 14, 2011

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.

[code]...

is what I have installed. Most of the suggestions I have found suggest deleting the entry for the remote host. Problem is it never gets created. How do I go about fixing this? This is a link to the last howto I followed, after the re-install of Openssh. [URL]...

General :: SFTP Chroot - Unable Move Directories To Other Locations Of The System

Sep 26, 2010

I tried setting up sftp for my users. Each of my user have their home directory at "/var/www/public_html/$USER". When my users are using sftp, they can only see their own directories and unable to move to other locations of the system. I followed through the following tutorials: [URL]

The users are able to sftp into the system successfully. However, they are able to see the whole system. Somehow, it appears that the users are not jailed in their home directory although in the tutorial it states otherwise. The difference of my system against the tutorial is that I am using Dropbear for SSH server while it is using Openssh server. Although dropbear does not support sftp, I am able to login through sftp through the use of sftp-server. For the internal mechanics, I am not sure how though.

Assuming that when I tried to SFTP, the sftp-server is ran with the sshd_config, then everything should be working fine right? Do i need to run chroot command at all? The following is the procedure I used to attempt the objective:

1) Add a new user to the group: SFTPonly
2) Chown user:SFTPonly user/home/directory
2) Modify the sshd_config to what is reflected in the tutorial and other paths.

OpenSUSE Network :: 11.4 Zypper Digest Verification Failed

May 17, 2011

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:

[code]...

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.....

General :: Certification Verification Is Failed / Don't Want To Terminate Operation

Aug 6, 2010

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.

For example:just downloading the missing part of the file ? (I have control over the server in order to install or configure what it needs to be done).

CentOS 5 :: Limit To One Connection Per User For Ssh / Sftp?

Dec 3, 2009

Is it possible to limit each user so that only one can connect via each username for ssh/sftp? I work with a small company where there aren't really enough of us to justify using a revision control system, but we don't want to accidentally step on each other's toes, so we'd like to try simply preventing more than one person from accessing a given domain at once.

CentOS 5 Server :: Rssh Error Connection Closed - Restrict The Users To Scp And Sftp

Aug 6, 2011

I have configured rssh 2.3 with openssh 5.8 on RHEL 5.6 64 bit to restrict the users to scp and sftp. When i try to sftp or scp it gives error connection closed. After long googling tried different solutions like add missing libraries, setuid to rssh_helper. I had full copy of /lib to /chroot/lib and /chroot/lib64 but no success. conf and log files are below for reference.

Ubuntu :: Separate Virtual Host To List And Display All Contents In /var/lib/php5?

Apr 3, 2011

I have an ubuntu 8.04 server running a couple of web sites using virtual hosts , apache2, mysql and php. I have noticed that by default php sessions are created in /var/lib/php5 and all stored in plain text.

I have quickly created a php script in a separate virtual host to list and display all contents in /var/lib/php5 , and it seems incredibly easy to see what details the other accounts are storing in sessions.

Fedora Networking :: Mount To NFS Server Failed - No Route To Host

Jun 22, 2011

I am trying to access a DVD mounted on a machine running Fedora12 (192.168.0.105). I thought this should be possible with NFS, but the above error message is what I keep getting, no matter what I try.

Here is my mount command:
Code:
mount 192.168.0.105:/mnt/dvd -t nfs /tmp/scaleo
The Fedora 12 machine has the NFS server running, and the corresponding entry in /etc/exports is
Code:
/mnt/dvd *(ro)

I thought this might be a firewall problem, but it persists even if I turn firewalls off on both machines (client as well as server.) Also, doing
Code:
ssh 192.168.0.105
is OK, so what is wrong with the route?

I am trying to access a DVD mounted on a machine running Fedora12 (192.168.0.105). I thought this should be possible with NFS, but the above error message is what I keep getting, no matter what I try. Here is my mount command:

mount 192.168.0.105:/mnt/dvd -t nfs /tmp/scaleo

I now tried
Code:
mount 192.168.0.105:/mnt/dvd -t nfs4 /tmp/scaleo
and it seems the mount succeeded. So, instead of nfs, one must write nfs4?

CentOS 5 :: Migrate A Host From Oracle Enterprise -> CentOS?

General :: Connect To An SFTP Server From A Windows Machine To A SFTP Server Using A DSA Key?

Jul 24, 2011

As a Windows user, I generated a pair of DSA keys from CoreFTP Lite and sent it to a third party that runs an SFTP server. They told me that a valid DSA key needs to have ssh-dsa at the start and the username@systemname at the end. CoreFTP generated neither the ssh-dsa header nor the username@systemname footer. I tried with WinSCP and it didn't generate them either. Is there a difference between how SFTP works between Windows and Linux? If I put a useraccount@systemname at the end of the text will it work? How would the Linux system validate that my system is called "systemname"? If it can't validate, what is the purpose of adding it?

OpenSUSE Install :: Unable To Upgrade To 11.4: Can't Resolve Host / Error Code: Connection Failed?

Apr 1, 2011

I'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).
