We have an exisiting website written in Python and was developed by other entities and now being maintained by us. We want to run the website using secure connection (HTTPS), I tried reading this article and successfully executed every instructions but still failed to run the website using HTTPS.

The way we run the website is using port 8080, e.g. [URL] I am sure I am missing something here, first, I am still looking on where does the port 8080 comes from since I've checked the httpd.config and it wasn't there.
Ubuntu Servers :: SSL Setup - Connection Error Unable To Make A Secure Connection To The Server
Feb 10, 2011I 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.
General :: Use A Rs232 Device That Uses The Usb Port?
May 18, 2010been trying to use a rs232 device that uses the usb port. it calls for a virtual com port to be created. i am running on ubuntu 10 and get hella confused with the search results i have come across.some call for the usbdevfs which apparently doesn't exist under lucid. another had me do use some "magic" in getting it to work.they provided a script mountusbfs.sh
Code:
#
# Magic to make /proc/bus/usb work
#
mkdir -p /dev/bus/usb/.usbfs
[code]....
of course when i tried it the domount command doesn't exist so i modified the above script replacing the domount with mount and it seemed to do something things. usbview is specified as the determining factor whether or not you have the usbfs mounted properly. it wants to use proc bus and ubuntu doesn't use that anymore apparenlty. i have read that i need to enable a usbmon (flag?option?) in the kernel to be set. which it isn't when i followed the steps to check.

View 8 Replies View RelatedCentOS 5 :: Open Port For Secure Imap And Smtp ?
Apr 16, 2011The server I'm running is virtually stock CentOS - it's running on a xen virtual host, started as CentOS 5.1 (32 bit) when that was fresh, it's at 5.5 now and updated nightly. All packages except postgresql and php are from CentOS and EPEL.
I'm running dovecot on it, and for long time, squirrelmail connecting via localhost was good enough. All external ports were firewalled by the CentOS firewall (just 25,80,443,custom ssh are currently open).
Now I need to allow an external imap client to connect.
I have generated ssl key and configured the dovecot configuration and it should be good to go, but gosh dangit, I can't remember how to open the port in the configuration.
I did it before when I set up ssh to run on a non standard port after I got sick of constant brute force attack on port 22, but I can't recall what I did and the various tutorials I find online all tell how to do it with the GUI tool, but I don't have any GUI stuff installed.
system-config-securitylevel-tui
Is I'm pretty sure what I used to open up my custom > 1024 ssh port, but I can't remember how I used it to open that port and it doesn't seem intuitive. Also, do I need to use 993? I'd almost rather use something custom above 1024, as long as thunderbird supports it (don't care about any other mail client)
Finally, my smtp server is postfix and port 25 is already open (but not an open relay, I check it about every 3 months). For requests to send mail from a client, I would really like some authentication of some type - as in only relays for IP addresses that have recently successfully logged in the secure imap port.

Red Hat / Fedora :: Netcat / Port Redirection - When A Connection Is Received On A Port Say 123?
Apr 6, 2010i am running ncat (netcat's new version from nmap) on centos . I am listening on different ports. My question is , is it possible that when a connection is received on a port say 123, i redirect this connection to a different port and use the 123 port again for listening connections. ncat has an option -k which u can add with -l , it will force fully listen on the port. It can accept multiple connections on a single port but i want that once a client connects on to 123 port, he is forwarded to some other port and no longer on 123.

Aug 30, 2010i have an embbeded hardware that uses bootp for booting from a Network Managemnt Host (NMH)on the same ethernet. The embedded hardware has both kind of ports i.e ethernet as well as E1/T1. I would like ask, what do i require to establish a communication-link between the embedded hardware and the NMH throuh E1/T1 ports of embedded hardware, so as to make it boot through from E1/T1. Further, NMH possesses only ethernet port. Just to refine my questions i'd like to know what additions do i need to do on my NMH , like may be i have to put an E1/T1 port or is it possible that the E1/T1 port can be directly connected to an ethernet port on the other host.
pardon me if i am not making absolute sense here as my knowledge is limited on Layer 1 and layer 2.
General :: Usb/external Drive Problems Redux - Read-only - Does This Suggest Device Failure
May 22, 2010I initially thought the problem had to do with the Lucid Lynx upgrade, a lot of people have been reporting similar issues with drive mapping and things along those line. My issue is that an external drive, formatted in FAT32 appears to be corrupted, and overtime begins to read or mounts as 'read-only.'
What I've read, and deduced, is that this is ultimately and issue with the drive. I've backed it up, reformatted, and been able to write to the drive successfully, but I've been moving a lot of files (backing up) and the system has been reporting input/output errors in transferring some files (through the GUI).
The only thing I can think of, is that the device itself is corrupted or damaged, and that I need to be thinking of other back-up options for the future. Any suggestions on disk-doctoring? I'm hoping to do a clean-install of the OS once I back up my files manually.

Ubuntu :: Specify Password In Script For Secure Connection?
Aug 3, 2010I'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).

View 2 Replies View RelatedGeneral :: Services Work Nicely With Connection Tracking - Port Range For Centos?
Dec 18, 2010On my CentOS 5.4 box I run dns, ssh, and smtp servers. This box also has to be able to resolve and browse websites. So basically it needs iptable rules for
TCP 22 25 80 443
UDP 53
My question is, which of these services work nicely with connection tracking? I'm a little confused about how connection tracking works. For example say this iptables rule for smtp
Code:
iptables -A INPUT -s 0/0 --sport 513:65535 -d $myip --dport 25 -j ACCEPT
versus
Code:
iptables -A INPUT -s 0/0 --sport 513:65535 -d $myip --dport 25 -m state --state NEW,ESTABLISHED -j ACCEPT
So with connection tracking what exactly does it do that my first iptables rule does not do?
Also for centos is that port range correct? 2.6 Linux kernel randomly chooses a port 513-65535 when it connects to an external smtp server or say browses a site.
