Why it works with FileZilla but not with Windows FTP from command-line?
More than that I would want a command that executed one time would download this file from that FTP without asking the password.
Any ideas?
Thanks.
It works in FileZilla, because FileZilla defaults to the passive FTP mode, which is more firewall/NAT friendly. The Windows FTP command-line client (ftp.exe) not only defaults to the active mode, it does not even support the passive mode, on any version of Windows. It makes it pretty useless nowadays due to ubiquitous firewalls and NATs.
Read my article about the active and passive FTP connection modes to understand why the passive mode is a must.
Use any other Windows FTP command-line client instead. Most other support the passive mode.
For example WinSCP defaults to the passive mode and there's a guide available for converting Windows FTP script to WinSCP script.
Your can specifically use a batch file (.bat) like:
winscp.com /command ^
"open ftp://my_username:password#1.2.3.4/" ^
"get setup.exe" ^
"exit"
(I'm the author of WinSCP)
I'm trying to move my bot to an Ubuntu virtual server from Vultr but it's having a problem connecting to the postgres database. I've tried editing the config from md5 to true, and host to local, etc. But those only give me different errors and also make it stop working on my original machine too. It's working perfectly fine on my Windows machine. Here is the error I'm facing:
asyncpg.exceptions.InvalidAuthorizationSpecificationError: no pg_hba.conf entry for host "[local]", user "postgres", database "xxx", SSL off
So I've tried to change this line:
async def create_db_pool():
bot.pg_con = await asyncpg.create_pool(database='xxx', user='postgres', password='???')
to this:
async def create_db_pool():
bot.pg_con = await asyncpg.create_pool(database='xxx', user='postgres', password='???', ssl=True)
and that gives me this error:
asyncpg.exceptions._base.InterfaceError: `ssl` parameter can only be enabled for TCP addresses, got a UNIX socket path: '/run/postgresql/.s.PGSQL.5432'
So I don't know what else to try. I've been stuck on this for a while. If it's relevant, it connects at the bottom of the bot.py file like this:
bot.loop.run_until_complete(create_db_pool())
Whether ssl is True or not, the database seems to still function on my Windows machine. But I can't get it to work on my Ubuntu virtual server.
If I edit my config to this:
# TYPE DATABASE USER ADDRESS METHOD
# IPv4 local connections:
host all all 0.0.0.0/0 md5
# IPv6 local connections:
host all all ::/0 md5
# Allow replication connections from localhost, by a user with the
# replication privilege.
host replication all 0.0.0.0/0 md5
host replication all ::/0 md5
Then I get a call error like this:
OSError: Multiple exceptions: [Errno 111] Connect call failed ('::1', 5432, 0, 0), [Errno 111] Connect call failed ('127.0.0.1', 5432)
This is really driving me crazy. I have no idea what to do. I bought this virtual server to host my bot on but I can't even get it to connect to the database.
When I simply type psql in the terminal, I get this error:
Error: Invalid data directory for cluster 12 main
Postgres is not working as intended in basically any way. I'm using Vultr.com to host the Ubuntu server, if that matters. And connecting with PuTTy.
Your pg_hba.conf has multiple syntax errors. The "localhost" connection type is not allowed at all, and the "local" connection type does not accept an IP address field. The server would refuse to start/restart with the file you show, and if you try to reload a running server it will just keep using the previous settings.

So i am trying to run Selenium tests written in Java through Eclipse on my guest machine.
My host machine is Windows 7 and I am running Windows 7 guest machine. I have set 2 network adapter NAT and Host only. I am farily new to the whole Selenium testing so I am still exploring all the stuff.
I already run hub and node on my guest with next commands:
java -jar selenium-2.39/selenium-server-standalone-2.39.0.jar -role hub -port 4444 -host 192.168.56.1
and node with:
java -jar selenium-2.39/selenium-server-standalone-2.39.0.jar -role node -port 5555 -hub http://10.0.2.15:4444/grid/register -browser "browserName=internet explorer,version=11,platform=WINDOWS" -host 192.168.56.1
from Eclipse i am trying to access hub on http://192.168.56.1:5555/wd/hub and http://192.168.56.1:4444/wd/hub but in both cases i get an error:
org.openqa.selenium.remote.UnreachableBrowserException: Could not start a new session. Possible causes are invalid address of the remote server or browser start-up failure.
Build info: version: '2.45.0', revision: '32a636c', time: '2015-03-05 22:01:35'
System info: host: 'xxxxx', ip: '192.168.xxx.xxx', os.name: 'Windows 7', os.arch: 'amd64', os.version: '6.1', java.version: '1.8.0_31'
...
I do not know if I am using the correct IP addresses in both cases, if i go into my browser on guest machine i can access the console from hub
Thank you in advance.
OK.
So after long playing with the setting I finaly made this working. First thing is I disabled the Host-Only networking and left only NAT and I've set up a port 4444 forwarding from my host (127.0.0.1) to guest (10.0.2.15).
I've run hub with
java -jar selenium-2.39/selenium-server-standalone-2.39.0.jar -role hub
And node with
java -jar selenium-2.39/selenium-server-standalone-2.39.0.jar -role node -port 5555 -hub http://localhost:4444/grid/register -browser "browserName=iexplorer,version=11,platform=WINDOWS" -Dwebdriver.ie.driver=selenium-2.39/IEDriverServer.exe
Later on in Eclipse under Debug Configurations under Environment tab i set new property (notice: it is custom property in this case)
xx.xxxxxxxxxxxxxxx.selenium.properties.remoteUrl with value http://localhost:4444/wd/hub
After running tests I could reach my remote hub.
I'm using "Net::SFTP" in perl cgi file to put files to a windows M/C from my dev box.
After adding below new directory manually (with 0777 permissions) everything works fine:
bash-4.1$ pwd
/.ssh
-bash-4.1$ cd ..
-bash-4.1$ ls -ltra | grep .ssh
drwxrwxrwx 2 root root 4096 Jan 23 23:57 .ssh
Problem (if I don't add above directory manually ) here is as per my understanding:
Apache is running cgi with user as "nobody" which do not have permissions to make directory after connection is established via sftp and I'm getting below error messages in logs:
xxx.xxx.net: Reading configuration data /.ssh/config

I tried to solve this problem with different methods given over internet but nothing is working for me.
Can anybody suggest possible solution?
Any help will be greatly appreciated.
I recently ran into the same problem myself and you are correct that it is a permissions issue. When your nobody process tries to connect to the remote server, it wants to write the remote host key to a file. This is the step that is failing in your error message (Hosts.pm line 92).
My solution was to create a nobody-writable location for the NET::SFTP to write the known_hosts file and to specify that location before you construct your NET::SFTP connection.
$ENV{HOME} = '/nobody/writable/location/';
You can find more information on this problem at http://www.perlmonks.org/?node_id=599078
Summary:
This is a 2 part question. A simple Samba share on one ISP with router doesn't work while another ISP with a different router setup the same and a similar server with same Samba configuration works.
It seems to be either the router not forwarding the ports, although it successfully forwards SSH and others, or the ISP somehow blocking the standard Samba ports. It still bugs me that I can't figure out why it doesnt work and I'll still try to narrow down the cause.
The second question is I'm looking for a business use, simple, easy to use (for end users), secure share for a small number of people and files, hosted internally and accessible externally on the internet, between Windows 7, XP, Mac, and linux servers with simple clients for end users.
A new friend outside of stackoverflow helped with sshfs as a solution. On CentOS ssh already supports sshfs. The Windows client win-sshfs is working well and I'll be trying OSXFUSE with MACFusion described at UO.
Additionally, setup linux users for each person. To allow write by everyone in the linux group, change the umask in /etc/ssh/sshd_config described in this question at serverfault. People get to their home directory first, where I placed links to a shared folder with sticky bit set so they can't delete the folder. They can delete the links but that's easy enough to put back. The only issues I can see are lack of file locking and lack of auto-refresh.
Original Question:
I can't seem to get Samba working on a Centos 6.3 server over the internet. I have a similar test server on another internet connection working fine with the exact same setup. I've gone through http://www.samba.org/samba/docs/man/Samba-HOWTO-Collection/diagnosis.html twice, made sure the ports are forwarded through to the internet (although not sure how to test they are really open), double checked samba configuration, its only sharing /tmp simply now. The user account is setup, it can ssh in and get to /tmp and the samba password is set the same. I can't ping the server but that is because the router or IP is set not pingable by the owner/work. SSH and HTTPS apache work well on the server with ports forwarded the same way. I haven't been able to test the share within the local network yet since I am not there, but I assume that it should work internally. When trying to connect from Windows 7 it just times out, no prompt and it has never connected, whereas my test server on my own internet connection is always working internally and externally.
Any help would be greatly appreciated.
The requirement is a easy to use internally hosted shared folder alternative to using "dropbox" for use between Windows 7, XP, mac, and linux servers that works over external internet connection. It won't see heavy usage but should be quick, easy to access/setup on the client side, and secure for business. If there are any alternatives to install on CentOS that would be great as well.
Thank you!
Andrew
Edit, details:
Ports are forwarded:
(I had an image but as new user I cant post) 137, 138, 139, 445 are forwarded all with both TCP and UDP for testing now.
smb.conf is setup simply and exactly the same as the working test server:
# cat /etc/samba/smb.conf
[global]
workgroup=WORKGROUP
log level = 3
log file = /var/log/samba/log.%m
max log size = 50
security = user
passdb backend = tdbsam
[tmp]
comment = temporary files
path = /tmp
read only = yes
Samba restarted for good measure:
# service smb restart
Shutting down SMB services: [ OK ]
Starting SMB services: [ OK ]
Windows 7 times out when trying to access the share as \ which works fine with the test server:
(I had a screenshot but new users cant post)
A search for the error 0x80004005 results in http://answers.microsoft.com/en-us/windows/forum/windows_vista-networking/cannot-access-network-share-get-unspecified-error/9f840844-9d5b-e011-8dfc-68b599b31bf5
I've checked the workgroup, share settings, and restarted windows. Since the test share works I would think the Windows machine is working. I'll continue with the details.
Edit again:
Following the troubleshooting guide again:
Simplify the smb.conf to just:
# cat /etc/samba/smb.conf
[tmp]
comment = temporary files
path = /tmp
read only = yes
/etc/resolv.conf is using the ISPs servers and they work. They are different than the working server's DNS but that one is on a different ISP:
# nslookup google.com
Server: 71.242.0.12
Address: 71.242.0.12#53
Non-authoritative answer:
Name: google.com
Address: 74.125.228.2
I'm doing everything with IP addresses so I don't know that DNS would come into play.
I added dns proxy = no to smb.conf for fun but that didn't help.
/var/log/samba/log.smbd doesn't report anything different from the working server:

Since the Samba ports do not show up, I'm thinking the router or ISP is not forwarding/blocking the ports at this point.
As for a solution to sharing, I'm trying sshfs with a windows and mac client.
Answering your original question, the good way to test if your ISP is not blocking listed ports is this:
# yum -y install tcpdump
# tcpdump -i eth0 "port 137 or port 138 or port 139 or port 445"
(substitute eth0 with the name of the interface connected to the Internet).
Then you should try accessing the share (net view / net use / Windows Shell). If ports are forwarded correctly you should see something like that:
tcpdump: verbose output suppressed, use -v or -vv for full protocol decode

...
If you see nothing at all it means that your ISP (or intermediate router) is blocking packets to those ports and it's most likely the case — SMB protocol proved to be quite insecure for open Internet deployments.
In the file /etc/samba/smb.conf, under the section [global], below the workgroup line add this two lines :
client min protocol = NT1
client max protocol = SMB3
