1. How to login SFTP sever by C/C++ with a TCP socket? That is meant format message to send to SFTP server ( TCP socket);
m_socket = socket( PF_INET, SOCK_STREAM, 0);
....
connect(,,) // connect to SFTP server
After that we must:
send( , message, , ) //send login message to SFTP server
What is the format "login message"?
I have a problem with sftp login to a Ubuntu server. sftp works for root, but not for other users.
ssh works as usual and for all users. code...
I've not been having any luck at all finding the answer to this, so thought I'd ask here: is there any way to get my servers to send an email when someone logs in through SFTP? I was able to get that to work with SSH using a simple bit of script in /etc/profile, but I can't find anything on Google about doing that with SFTP at all.
The OpenSSH version on my server is 5.2p1 running on FreeBSD 8.0. Any way to get the server to execute any command on SFTP login will be enough for me to get this set up.
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?
View 2 Replies View RelatedI've been administrating a dedicated Linux CentOS 5 (Linux 2.6.26.5-rootserver-20080917a) server for around 2 years, and although not a network or Linux expert, been learning to configure as need arises. Primarily using Plesk for day-to-day, but occasionally using Putty to SSH into server.
For all the time I've had the server, I've been connecting to my server via sFTP using "root" password. ( Although, I know this is really bad practice, I assume made safer by connecting with SSH FTP)
After spending another normal day in the office developing websites, connecting to my server as root using SFTP in Filezilla AND Dreamweaver I left for the night.
Returned next morning, after having done no manual updates or amends to my server; I could no longer SFTP into my server?
Thought it may be related to my office network, so tried it from home over the weekend, same result; can no longer connect SFTP for root?
I can connect to the server via Putty using my "root" username and password.
After spending hours looking on the internet for a solution, I'm lost for ideas as I didn't make any changes?
What happens when I open my Filezilla and try connecting as SFTP is it states:
Error:Connection timed out
Error:Could not connect to server
I checked server log /var/log/secure and it states:
Accepted password for root from UNKNOWN port 49212 ssh2
Apr 9 07:41:41 s15320264 sshd[7122]: fatal: Write failed: Connection reset by peer
Odd part is, it's worked fine for weeks, months without ever failing to connect?
Also, notice that Putty connection seems to take much longer to authenticate root user than it used to?
Checked via Plesk Health Monitoring and all CPU, Memory and Disk Levels are well below any alarm levels.
I have run all Plesk updates to 10.2.0 in the hope that it resolved it, but to no avail.
After customizing my .bashrc for a nice pretty shell locally I decided I wanted it to look nice remotely to I created a ~/.bash_profile in my home directory so I wouldn't have to type bash upon logging in I'd just be greeted with my colors and customizations. I placed the files on 2 remote locations and ssh'd in and worked just like it wanted it to, later that same day I tried to sftp in to one of the locations and it kept disconnecting me after I'd input my password, but I could still ssh in just fine. After trying a few suggestions from the web like [URL] with no success I decided to ask some friends. They narrowed it down to the motd and echo's in my .bashrc. Finally I asked a very experienced developer about it and so without further adue here is the .bashrc / .bash_profile
BASHRC:
Code:
PS1='[e[0;32m]u[e[1;34m]@h[e[m] [e[1;34m]w[e[m] [e[1;32m]$[e[m] [e[1;37m]'
# Source global definitions
if [ -f /etc/bashrc ]; then
[code]....
Unfortunately I forgot to mention to get it to launch the terminal with the greeting / fortune you have to have the echos uncommented in the .bashrc locally, or know more about shell scripting than I [wouldn't surprise me at all if someone is able to expand upon my bashrc and fix my minor problem] and have it not echo or execute fortune on sftp only somehow. So if you have fortune uncommented be prepared to be unable to sftp IN to the box that it is uncommented on.
I mean dir other than home dir.How do I do that
View 6 Replies View RelatedOn my Ubuntu 8.04.4 LTS webserver I desperately want to disable the Root account. But at the moment I am unable because I prefer to use Nautilus/Dolphin on my home laptop for SFTP. The graphical interface also helps when comparing multiple config files at once, something that being limited to NANO or PICO would make extremely painful. The problem is that if I don't use ROOT I can't perform any SSH or SFTP actions with a graphical interface, because I can't use SUDO without the terminal. Does anyone else leave root enabled? I have a non-standard port, disabled password authentication in favor of ssh keys, and I have a tarpit configured
View 2 Replies View RelatedI was using sftp to pull a file from a system and the transfer aborted with the message:
Code:
Received message too long
followed by a large number and I was kicked all the way out to a shell prompt.
Anyone know what problem might have caused this? I was using the Cygwin's sftp when this happened.
The file I was getting wasn't very large (5.5M) and certainly nowhere near the largest I've grabbed using sftp. Luckily the remote system was 'IX and I was able to dust off my memories of the "split" command (before USB drives became common, "split -b 1400k" was burned into my synapses) and reassemble the file once I got all the chunks transferred. Still, having to do this is weird.
I have setup SFTP and it is running without any problems. The problem I have is finding a client that supports key based logins through Linux. I do not want user based logins available and so far the solution works through my Windows machines using WinSCP. The only client I have found for Linux seems to be FileZilla but I have to convert my private key to the FileZilla format which removes the passphrase leaving it nice and insecure.
View 4 Replies View RelatedI have my original test version of sled11 which I installed when it was first released. I managed to install the required files for multimedia formats and everything works fine. The system has updated as updates have been released via the evaluation update code quite happily. I liked it and decided to get a sled11 license and install on my main workstation. About a month has passed since the test install and my fresh licensed install and I accepted all the updates on install. When I install the multimedia apps, only kaffeine will read multimedia dvds. Nautilus, brasero and totem say it is a restricted format and refuse to read it. What to look for?

Running CentOS release 5.4
We currently run a web server that allows FTP connections. I want to:
1. Disable FTP on our web server and require sftp only.
2. See if we can create a table of sites that are allowed to connect to the web server using sftp. Or should I just do this at the firewall?
I can't sftp directly into a particular host. To move a file from my home machine to the host, I must sftp a file to an intermediate host; ssh into the intermediate host; and sftp the file to the final destination. Is it possible to avoid such madness?
View 5 Replies View RelatedI am using Ubuntu 9.10 to configure telecom equipments. The software downloading process to the equipment requires that my Ubuntu laptop should act as a SFTP server where the software bundle for the equipment is stored. The equipment act as a SFTP client and requests the software from the server. The equipment have SFTP client hardwired in its memory. The same process i did with windows and i used Putty and FreeFtpD and it worked. Now i want to move to Ubuntu as i want to show that it is better. I have installed OpenSSH server in my laptop and now i need to know few things that i could not find anywhere straight forword.
1)I am using a ubuntu live usb drive with persistancy. How do i set username and password for the client, that is how to create the account in OpenSSH server?
2)I need to keep the software for the equipment in a folder inside server, so that it can be transferred to client upon request. In windows I give the path of the folder to FreeFtpD server. How to do the same in OpenSSH server?
Setting up servers and clients in linux is completely new for me.If this is done (as i know it can be but dont know how) then i can completely move from windows to Ubuntu environment.
I just updated my CentOS 5 installation to 5.2 using yum update command.
But soon after restart, I can't use FTP anymore.
I tried SFTP but it always ended with "out of memory" message.
And last way, I tried to uninstall ftp and replace it with vsftp but still cannot solved.
Now I don't know how to upload my files to this server :(
I have done a minimal install of jessie stable on a 2004 laptop with openbox as the window manager.

I can use cli and connect using both sftp and ssh.

View 3 Replies View RelatedI cannot access a remote server(Ubuntu) using ssh or even using sftp from my ftp client. I've been accessing this server regularly for many months with no problem until now. There is a web server running and that's OK, so no problems there. I asked the owner of the server if he could access using ssh from within his LAN, which he could! So openssl is working from within the LAN, but not ouside of the LAN. I access the remote server by using one of [URL] free domain names. I'm aware that this service requires renewal or activity at least once a month and as far as I know this is up to date and working OK.
Is this a router gateway problem? I suspect that port 22 has been blocked, but what could block this port? It's been working well for so many months. As far as I can tell the owner of the server/LAN has not been tampering with the router, so what could be blocking port22? I'm currently accessing the server using vnc4server.
Another really weird thing is that when I access the terminal on the remote server via vnc4server and I ssh back to the server using one of [URL] free domain names, it works! So as I understand ssh is accessing itself by going out of the LAN and back to itself. This would suggest that port22 on the gateway router is working. But when I try to ssh from a pc outside of the LAN, I just get timed out!
* openssl working from within the LAN but not outside of the LAN.
* sftp not working.
* domain name from dyndns.com working and up to date.
* Web server is working OK.
I would like to transfer files from my PC to my account at a sftp server, and I don't know how to do it.
My PC is running with:

User: SFTPUser1
Address: sftp-server
I can access the sftp server with the command:
Code:
sftp SFTPUser1@sftp-server
The sftp server doesn't answer to ssh requests.
How can I transfer files to the sftp server?
I had an ftp server about a year ago. It was running off of windows 2003, and didnt have any protection on it besides the normal firewall and NAT router. I shut it down after a couple weeks because i was constantly getting password hackers and weird things trying to break inused Ethereal to monitor packet traffic).Anyway, ive decided to take another swing at it and try to configure a more secure server on a more secure OS. I've found multiple HOWTO guides by surfing google BUT most/all of them want me to download a file called "openssh-4.5p1-chroot.tar.bz2", however the address they all point to does not exist! That address is so my main questions are where can i find this file? Is there a better one that would work? Is there a tutorial someone knows about that would get me past this?
I built a computer last week for this purpose (only had to buy a few parts so it's not like i spent $500), and now i feel like ive hit a dead end just cause a site decided to take a file down and no one else has realized it's happened except me.
How to configure sftp in RHEL3 or RHEL4
View 3 Replies View RelatedRunning: Red Hat Enterprise Linux Server 5.2 (Tikanga) I need to be able to automate transferring a few files over from one server to another using scp or the sftp protocol. I have received a text file which looks like a key file along with username and passphrase information for the target server in question.
Instructions were given to me to import the provided text file in puttyGen then save the imported key as a private key to be used by scp or sftp. My assumption is this is for windows utilities, which I am not using. My frustration comes in trying to automate logging into this server via sftp or scp to automate some file transfers. I am asked for a password every time because the public and private key methods failed to find my keys. How can I call scp or the sftp utilities and use the provided key file (the one I generated using puttyGen or the original one provided to me) to login to this server? I've tried taking the generated ppk file from puttygen and adding it with the ssh-add command but that still did not work.
how to setup ftps & sftp in RHEL 5.4 Server.
View 4 Replies View RelatedMy website, IsleDiscount.com, is hosted on a virtual server with pair.com. Pair.com offers only one SFTP account on regular shared server and to set up mutltiple SFTP accounts, Pair.com moved me to a virtual server (VQS1), which I believe is not a shared server solution, but Pair representatives were able to create multiple SFTP accounts on this VQS server.
However, when I asked the representative to restrict access of this additional SFTP accounts to a sub-folder, I got the following warning email: confirm you understand this will make your entire web directory world-writeable. This will increase the chances of a security attack. If you do understand this, you can go ahead and execute the command yourself. The command below will accomplish both commands in one.
