Server :: SFTP - Folders Become World Writable?
Jan 21, 2011
My 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.

Being a system administrator i came across a statement as "Excluding temporary directories /tmp and /var/tmp, no root owned files should be in world writable directories"While the above statement may look straight forward but how would i check if there are any such directories in the distribution?

I have an account in university on Linux machine with 10TB of free space accessible via SFTP. I would like to backup my Windows 7 x64 laptop to university. Currently I am using rsync+cygwin, but backup is pretty slow (without shadow copy) and I hate console window appearing every day on my screen when I login.
So I am looking for something like Windows Backup but with support for SFTP. Combination of tools will work too.

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?

I am trying to get write access to a share on xp machine via automatically mounting
the share via the following /etc/fstab entry .... after doing a sudo mount -a ... I can view the files on the 'C-share' but can not write them back to the server
//WINBLOWS/C-share /media/C-share cifs,rw
This used to work and allow share files to be read and writable before some ubuntu updates.
I am currently running ubuntu 9.10.
PS: if I connect via places->network ... the files are readable and writable ... but I need this setup to be automatic with a mount for someone else.
What needs to be added to the above fstab entry

We have a Dell PE6600 with a QLA2460 FC HBA in it. Server is running RedHat AS 4.7 (kernel 2.6.9-78), FC driver used is the file qlafc-linux-8.02.23-3-install.tar downloaded from the QLogic website. On this server is an Oracle database running (11.1.0.6). Files for the Oracle database are located in mountpoint /u02. The SAN is an iQStor 2880. Since several weeks we suddenly have problems with the Oracle database after a reboot of the server. After a reboot the mountpoint /u02 is readable and writable (tested by creating, opening and removing files).
However, when we try to start the database we get an error which give you the idea that the database is corrupt. The Oracle error is quite a general error. After doing a lot of testing we found out that if we unmount /u02 and mount it again (using mount -a so it reads the /etc/fstab), the database can be started after all. So the database is not corrupt but for some weird reason we have to remount /u02 first before the Oracle database can use it. We don't know if it's a linux issue, fibre issue, san issue or an oracle issue.

Got a few servers runnning and they all connect fine to the net. Each are running with a static IP provided by my ISP. But I have one server were I re-installed Debian Lenny - or tried to. At the stage were it wants to connect to a mirror it cannot due to network problems. I tried a new install leaving it behind a router. This solved the problem and it connected. Tried once more directly connected to a static IP and same problem happened - it got to the point with the mirror. Tried changing the settings after the installation through the router. This is what I get from ifconfig :
[Code]...
If I ping it from one of my other servers it shows as OK and can also ping my other servers from the server in question, but if I ping google.com it times out (fails). The IP 92.62.196.77 is in the range that I can use. Checked that with my ISP. Just to make sure I tried disconnecting one of the servers that I have working and changed the server in question settings and still it came out with the same problem.

I have run into a problem using FreeNX in combination with public key authentication. I have Googled myself silly, but I can't find the exact answer to my problem. I am hoping that someone here will know the answer. First, let me tell you what I am trying to accomplish:
- I don't want my ssh server exposed to the Internet with password logins enabled. I only want public key authentication.
- I want to have access to NX server from anywhere in the world.
- I want NX to use a custom keypair, not the default supplied by FreeNX.
My environment:
openSUSE 11.2 (client and server)
KDE 4.3.4 (client and server)
FreeNX-0.7.2-26.5.i586 (server)
openssh-5.2p1-9.1.i586 (client and server)
NX Client for Linux 3.4.0-5 from NoMachine (client)
qtNX Client qtnx-0.0.1SVNr281-215.1.i586 (client)
The login problem persists, whether I am connected to the same network or to another network. Since ssh logins work, I don't think a firewall is the culprit. What do I have working so far: - The ssh server on the remote host only accepts public key authentication and I can login from the client without problems. So far so good. - FreeNX is installed on the remote host, using a custom keypair.
Authentication with this key works. I can login from the client with the nx user and the public key.

I can't seem to set this older server right to deny outside access while I build a website on it. What I am trying to accomplish is deny anyone outside of my network access to the website, but replace the 403 error with a temp page letting them know it is coming soon. I have googled for hours and everything I have tried just denies me as well. Seems to be all or nothing.
My last attempt was:
Code:
<VirtualHost *:80>
ServerName www.mydomain.com
ServerAlias mydomain.com
ServerAdmin me@mydomain.com
DocumentRoot /home/me/www/site
ErrorDocument 403 /temp.htm
<Directory />
Options FollowSymLinks -Indexes Multiviews
AllowOverride None
Order Deny,Allow
Allow from 192.168.0.*
Deny from all
</Directory>
</VirtualHost>

I went away from home for a few days, ... Now I am back at home and noticed, that my server is going out with 100% available bandwidth. The server is mainly Http / Ftp / Mail server, so I stopped all services, to see which one it is. ervices stopped, still 100Mbps go out like ants in the flood.
I updated the system, made a backup, installed IPtraf. It seems that I have something 'installed' and my server is running something to attack User computers. It seems to try to find something on random IP's random ports. I am a little bit confused now. As long as my sites are running, I'm ~OK~ but sooner or later I would like to have my bandwidth back. How could I try to hunt down which service/app/process got hacked?
It seems that the monetary system of our society got now more enemy's than friends. Capitalism seems to reach it's end. But my server is serving also ART! Sooner or later we will need to pay copyright even for our thoughts. I was reading today, that the French president wants to punish file sharing as his wife made 3 albums, and wants to get some money ..

I'm trying to decide on how to host and serve files to multiple operating systems (Linux, Mac OS X, Windows XP and Windows 7) over the internet. I'd like this to be secure (obviously), but don't want to use SSH tunnelling.Ideally, this would be something which could be persistently mounted on the client machine (a network drive in Windows, likewise in Mac OS X and Linux) and wouldn't require the installation of extra software on the clients. I thought about samba, but I'm not sure if it's secure enough to be internet-facing. Would FTP fit?resumably it's possible to have encrypted connections only and limit connections to a specified number of client IPs.

I have a Belkin N router setup with a virtual server to port 80 to 192.168.2.2 which my server sits on.
However, for some reason, I can get to the server from other PC's on the Router, but from outside, it will not port to the Server?
Any ideas on how to setup this?
I have Windows Webserver 2008 installed running on a 3.0GHZ Server.

I am having trouble getting my FC10 with tomcat visible to the outside world. first off i am somewhat new to linux. I am running vmware workstation to host my linux web server. i have my VMWare setup to use my second NIC solely. it is bridged and the tcp/ip is disable from the host. i can ping the ip address but cant access tomcat on port 8080 from the outside. i can hit it fine from inside fedora. i have configured my router (wrt54gs with DD-WRT firmware) for port forwarding. so basically i think that the problem is somewhere in between the host and the vmware configuring allowing the port to be forwarded through.

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?

I 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 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: User1
Address: 10.0.2.3
My sftp account is:
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?
