Ubuntu Servers :: SSL Setup - Connection Error Unable To Make A Secure Connection To The Server
Feb 10, 2011
I am running an Ubuntu Server on a VirtualBox VM running on my windows machine. So I've created a self-signed certificate using the following tutorial: [URL]
From this tutorial I'm left with 3 files:
server.key
server.csr
server.crt
Then I found this very similar tutorial that has an extra bit on installing the certificates in apache: [URL] So I followed it's instructions which boil down to this:
[Code]...
So I'm thinking this should work now. However in Chrome I get: SSL connection error Unable to make a secure connection to the server. This may be a problem with the server, or it may be requiring a client authentication certificate that you don't have. Error 107 (net::ERR_SSL_PROTOCOL_ERROR): SSL protocol error. IE8 gives me a typical "Internet Explorer cannot display the webpage" Note that [URL] fails while [URL] works fine, so it's definitely something in my ssl setup I'm thinking.
My server is suddenly getting giving the following error: Quote: Secure Connection Failed An error occurred during a connection to inenergy.dvrdns.org. SSL received a record that exceeded the maximum permissible length. * The page you are trying to view can not be shown because the authenticity of the received data could not be verified. * Please contact the web site owners to inform them of this problem. Alternatively, use the command found in the help menu to report this broken site. I had been trying to configure the server to do secure logins (before Christmas) , but I don't think I had completed the configuration and I'm not sure how to reset it so that I can start again.
I am trying to Setup citrix ICA client 9 on Ubuntu 9.04 Server. I installed it very easily and I am not getting any lib error also. But when I try to connect to the citrix server, it fails with a pop up saying "Error in Network Connection Network or Dialup connection may be preventing ......" This is driving me crazy from 3 days. My project is to check the feasiblity of a Linux desktop
I currently run Win 7 and want to upgrade my computer to a server to accomplish the following... I have a VPN Service. I want the server machine to connect to a VPN providing a secure connection. Then, I want all the machines in the house (windows based) to connect through the server onto the VPN connection. Hopefully this makes sense. Would it be better to stick to Windows Server 2008 or switch to Ubuntu?
I followed the tutorial found here [URL] but when I try to access [URL] I get the following: Code: Secure Connection Failed An error occurred during a connection to www.mydomain.com. SSL received a record that exceeded the maximum permissible length. (Error code: ssl_error_rx_record_too_long) Not sure what I might have done wrong... I have retraced all of my steps and I don't believe I missed anything.
Linux printing appeared to be working fine up until yesterday. Today typing lpq gives the following: lpq Printer 'sdst@other.domain' - cannot open connection - Connection timed out Make sure LPD server is running on the server
The /etc/cups/printers.conf file is properly set, the printers appear in localhost:631 and they are printing test pages. However, all command line print commands seem to be trying to print to sdst@other.domain I don't know why printers.conf is being ignored and why and how sdst@other.domain was added. Seems like it might have been auto-discovered?
# dit: sdst@other.domain was mentioned in /usr/local/etc/lpd.conf I'm not sure why lpd.conf is being used instead of /etc/cups/printers.conf
I can make a connection to the vpn server, the connection starts, but nothing happens! My IP address remains the same as previous! There is nothing added to my Knetworkmanager, I'm a beginner I should use a pcf file for my vpn connection. I use it properly, I'm sure because the connection starts and an icon is added to my panel and remains until I disconnect.
I checked it via ifconfig -a, the last part (which is for vpn) is:
I'm try to setup a database server using mysql, the server starts fine, and I can access it using the built in mysql client via console (adding databases and tables works fine), but the problem is... I always get a connection refused error whenever I access the database outside the built in mysql client (example, if I write a code that connects to mysql). So, I tried execute an nmap command and the only ports open are these ports:
[Code]....
there's no 3306 for mysql... I'm thinking that the firewall is just blocking the port that mysql is using, but my question is, how could the built in client connect to the server if there's no open port for mysql server? Don't clients usually access a servers through ports?
I am merely trying to change the port for my ssh server.However it isn't changing.I edited my ssh_config file to:
Code:
# This is the ssh client system-wide configuration file. See # ssh_config(5) for more information. This file provides defaults for[code]...
When i try to connect to my server via port 443 i get a connection refused error. However when i try to connect via port 22 it connects. Since that didn't work, i tried restarting the entire server.To restate, i changed the config file and restarted ssh then the computer, however the port didn't change.Ohh and yes my router is set to port forwarding on port 443, though it doesn't matter since I'm inside the network.
how to setup a secure and reliable server, i have three ubuntu 10.10 servers a Dell PowerEdge 850,1850 and 2850 which has a Dell PowerVault 220s attached to it.The Dell PE850 Server Consists of:
Intel Pentium D 3.0GHz 4 GB RAM Eventually 2x250GB Sata Hard Drives
I would like to setup a reliable webserver, mail server, DNS and Dynamic DNS, DHCP, SQL, FTP, Samba (with Roaming Profiles), PXE Boot Server.I know how to setup most of the server modules, i would just like to know the best way to do it tho. I also want to no how to setup the secuity of the system correctly, and setup and partition up my hard disks to allow for the best reliabilty, even when a server crashes.I would like to now how to set these servers up from start to finish in a sence.
I am going to set up a file server on Ubuntu. I have searched a while, but can't seem to find a guide to what I want. The requirements specifications are the following:File server: possible to upload, change and download files.Linux (Ubuntu) clients, Windows clients if possible.Access restriction to deny access to other than registered users.Only the user should be able to read the content of the files.Ideally root should not be able to see the individual files, but in worst case it is ok for root to see the files.Root should not be able to open the files.Point 1-3 is easy to find out how to set up. But I can't seem to find a way to deny root to view the files. The only solution I can think of is to encrypt files or a whole folder, but I don't know how to set it up.
The setup is for a home network, but the server used as a file server will have a web server as well. If someone manages to get access to the server I don't want them to be able to read the files.
am running centos5.3 on a virtual machine and was trying to do some basic hardening and part of it i had to modify the pam.d/system-auth file and from then i am getting a fatal error whenever i try to connect via ssh using putty i am not at all able to login the server with any of the accounts even root also.I am scared unknowingly did i lock the system???how to resolve this issue?
I have FileZilla installed on this machine, and OpenSSH (with an open port 22) on another machine on my home network. When I try and connect, I get: Quote: Status:Connecting to 192.168.2.3... Response:fzSftp started Command: open "alphatwo@192.168.2.3" 22 Error:Connection refused Error:Could not connect to server
Which has left me puzzled as I have an open port. Does the username have to be defined somewhere? E.g. the machine acting as my SFTP server can be logged on to locally as alphatwo so that's what I logged in as (with the correct password). Is this correct? If so, does anyone have any ideas as to how I might rectify it? I want SFTP set up so I can copy PHP files from my laptop to /var/www/html/ on another PC (across the home network).
I've very recenty installed Ubuntu v 9.10(64amd) but am unable to setup my internet connection.I've gone through quite a few posts where other users have faced the same trouble trying to setup a DSL connection.I've entered all my Ip4 settings as they are on Win..but that hasn't helped.That didn't open my modem settings page either.Modem model : SmartAX MT882 connected via Ethernet and not USB.Can't quite figure out what I'm doing wrong/need to do.
I am trying to setup multipath with failover policy on openSuSE 11. I have two qla2xxx HBA's installed and they appear to be working. Here is the output of "multipath -l" command
[Code]....
While testing, I pulled one of the two connection to SAN, and the connection failed over to second HBA connection to SAN. When I plug the cable back in, it does not fall back to original connection... It stays in failed state. Also, I noticed that failed disk (sdd disk) comes back as (sdg disk), which is probably why connection does not fall back to original HBA. But, when I run "/sbin/service multipathd restart" sdg disk shows as as enabled in multipath -l...
I have recently installed Ubuntu 8.04 LTS Server Edition, with no GUI. I can't connect to internet, and therefore I can't use commands like "apt-get update" I do not even know how to configure this server yet. I need my server to connect to Internet through my wireless card (I have no cable connexion for now).
I am new to ubuntu and I'm trying to set up an vps, but I cant manage to get past the first screen where I have to fill ip and port 22. When I click open, it says connection refused.
I'm trying to setup PPPoE connection to establish my DSL connection, but I got
Code: pppoe[3885]: read (asyncReadFromPPP): Session 4479: Input/output error pppd[4104]: Cannot determine ethernet address for proxy ARP in my sylog file.
When I do pppoe-start, it connected but I cannot ping into any destination (even to my modem in the same network). DNS servers are explicitly set in pppoe.conf and resolv.conf. Did I miss anything?
I installed the Kde desktop and i'm unable to setup a broadband dsl connection i have done the settngs in network manager gave password username service name etc. but the option for connection doesnt appear the connection works properly in windows as well as gnome 3 desktop but not in kde
I have a problem between a jail root (so a group of users can access through sftp to Apache directory (var/www) an not get out of this directory.
1. I have the group 'sftponly', I need to access / var / www for sftp (read only)
2. On the other hand I need that user www-data (Apache) is the owner or at least have write permissions in the same directory (/ var / www)
The problem comes when the two needs together, as from what I read, to do jailroot in a directory is necessary for the owner is root and any other user has write permissions on it.
If along the jailroot with write permissions then attempt to connect to the client via sftp throws me the following error: "Error: Server unexpectedly closed network connection"
Permissions system User/group/Others doensn't work to me, so I tried it with ACL, but I have the same problem when I grant write permissions to the apache user.
Does anyone know how can I do for the user www-data can have write permission in the Apache directory and be able to create a user or group of users who are "locked"in this directory to enter sftp?
I think I've read every post here about the Broadcom and connection.I thought I tried everything.Turns out (read Chapter�35.�Using NetworkManager) using Connection Manager (K Network Manager) you can not use, what I wanted to use, 'all users, use connection' or said another way, the wifi would be activated and connected Before the user 'logs in'. Well, as I said, it turns out that if you are using gnome, this will work with NetMgr, but NOT in KDE. If you want to use 'system connect' then you have to use 'traditional' if in YaST2. Oh well, at least 'i'm' connected.... (i'm the only user, so not a big deal right now, but would like to get it working...)
I have a new Ubuntu server (10.10), named Denholm, recently installed and updated. I came in this morning, attempted to add a package with apt-get, and got a "Connection refused" response. I have another server (also 10.10), named Moss, on the same network that can connect successfully.
Here's what I've found/tried so far:
This doesn't look like and apt problem anyway, but the sources.list files on Denholm and Moss are identical.
I can ping [URL] (and other sites) successfully from Denholm.
I have tried 'wget www.google.com'. From Moss the wget is successful, but from Denholm I get "Connection refused."
I have a web server on Moss and Denholm can successfully access it.
To the best of my knowledge, Denholm is not configured to use a proxy server (no http_proxy variable set).
I'm going to start a new thread because previous searches have not totally satisfied my question. I've read all day about doing this but each inquiry leads to discussion of configuring the router. I am also not network savy. I would like to set up an FTP server on my home computer (presently Ubuntu 8.10). I have only one computer. I am using DSL with my telephone line for internet connection. I do not use a router.
Is it possible to do this with no router and only a DSL ISP connection?
I got an error while working with NetworkManager in new RHEL6/ Fedora14. I have a ZTE AC 2726 3G wireless modem. i had tried to connect it via NetworkManager . It only requires username and password to connect but the thing is that after putting all the credentials i had checked the option" available to all the user "and while i was trying to save the profile it shows the following error saving connection failed 0 can't write connection type 'cdma'I had google so many times around this error but no better solution is there .
im on node1 when i type the command ssh node2@ip the terminal hangs up a bit then an error message stating that connection timeout but here is a thing: i cant ping to node2 but i can terminate the ping manually using ctrl+c when i terminate the ping usual message appears stating 10 packets transmitted, 100% loss
ps: when i go to node3 and ssh to node2 it works fine and also i can ping from node3 to node2 very fine. and the firewalls are down at all nodes -all wired connection over a switch
I am facing some strange problem of mysql replication with ssl, my replications which working fine from more than 6 months currently stopped working after i upgrade mysql in to newver version mysql-5.1.41-2, i create new ssl self singed certs but still no sucess, when client try to connect the master using ssl its gives error SSL connection error ERROR 2026 (HY000), with out ssl its working f9.
I can seeking the problem on net, and i found the below bugzilla url related to that.
[url]
I read it but not get , either new version support x509 ssl certs or not or either new version support ssl replication or not, here below my server configuration for ssl serts
And for client
Both server and clients certs are signed with same ca but still its currently not working after the mysql upgrade first 5.1.41 and then 5.1.41-2
Either as above bugzilla url, currently mysql support ssl replication or not, or either some need to do special for working with ssl. or i wait for newver version of mysql to fix if its bug or not.
I want to settup a proxy server who just redirect the internet connection to my second computer. I try Squid Proxy but its too complicated for me. Can you sugest me another more simple program to do what i want?
I'm writing a script that tars, bzips, and encrypts a set of files to my GPG key and then (ideally) uploads the files to a backup directory on my school's web server. I want to run it daily as a cron job. Problem is, the web server only allows connections with scp and sftp.
Neither program allows specifying a password as a switch. I want to run it as a cron job, so I won't necessarily be present to type the password, and I'd like to just be able to specify the password in the script.
"Ah ha!" you're thinking. "He needs to generate a keypair and set up ssh to not require a password!" And I've found tutorials on the web that show me how to do just that. Problem there is that they all require me to install software and/or access files outside my home directory on the remote machine.
I have zero access to anything other than my own home directory on the remote machine. None. Nada. Zip. I can't install software, access files in /var or /etc, or find out anything about running processes. The local IT priesthood won't give me any information about what's running on the machine or how I can connect to it (and has made a point of telling me that they don't care for Linux users and I should stop asking questions).
I'd really like to to just be able to specify my password in the script. I understand that scripts are really just text files and that anyone who can get at my desktop computer can read them with a text editor and that this would reveal my password and blah blah blah, but I'm willing to trade that particular risk for the convenience of not having to be awake and monitoring the computer when the cron job is running.
Is there any way to specify the password in the script itself? I'd be happy using either sftp or scp (I've used them both successfully from the terminal to transfer files to this machine).
I want to secure my internet connection by hiding my ip with another ip so I can log to my server with 2 ips . and when someone is tracing the "fake" ip it wont affect me .
