vsftpd server unreachable

jonaskellens · 01-20-2014, 05:34 AM

Hello,

I have installed the vsftpd ftp-server from yum on my Fedora 19.

But the ftp servive is only reachable on the client itself :

Code:

[root@jonashp ]# tail -f /var/log/vsftpd.log 
Mon Jan 20 12:00:21 2014 [pid 5459] FTP response: Client "::ffff:192.168.1.101", "220 (vsFTPd 3.0.2)"
Mon Jan 20 12:00:24 2014 [pid 5459] FTP command: Client "::ffff:192.168.1.101", "USER polycom"
Mon Jan 20 12:00:24 2014 [pid 5459] [polycom] FTP response: Client "::ffff:192.168.1.101", "331 Please specify the password."
Mon Jan 20 12:00:25 2014 [pid 5459] [polycom] FTP command: Client "::ffff:192.168.1.101", "PASS <password>"
Mon Jan 20 12:00:25 2014 [pid 5458] [polycom] OK LOGIN: Client "::ffff:192.168.1.101"
Mon Jan 20 12:00:25 2014 [pid 5460] [polycom] FTP response: Client "::ffff:192.168.1.101", "230 Login successful."
Mon Jan 20 12:00:25 2014 [pid 5460] [polycom] FTP command: Client "::ffff:192.168.1.101", "SYST"
Mon Jan 20 12:00:25 2014 [pid 5460] [polycom] FTP response: Client "::ffff:192.168.1.101", "215 UNIX Type: L8"
Mon Jan 20 12:00:44 2014 [pid 5460] [polycom] FTP command: Client "::ffff:192.168.1.101", "QUIT"
Mon Jan 20 12:00:44 2014 [pid 5460] [polycom] FTP response: Client "::ffff:192.168.1.101", "221 Goodbye."

When I try to log on from another FTP-client in the same network, it does not work.

IPtables is stopped :

Code:

[root@jonashp ]# /sbin/service iptables status
Redirecting to /bin/systemctl status  iptables.service
iptables.service - IPv4 firewall with iptables
   Loaded: loaded (/usr/lib/systemd/system/iptables.service; disabled)
   Active: inactive (dead)

nov 17 14:02:16 jonashp.jocan.local systemd[1]: Stopped IPv4 firewall with iptables.

SElinux is also disabled :

Code:

[root@jonashp ]# cat /etc/sysconfig/selinux 
SELINUX=disabled
SELINUXTYPE=targeted

What am I missing ?

how do you know it is not working from another client?

jonaskellens · 01-20-2014, 06:13 AM

I tried connecting from another pc and with my smartphone with a simple ftp client. Used the same user and password. There is no connection, and there is nothing logged in the ftp logfiles.

please try to telnet on port no 23.

Hello,

It does not work. There is no connection at all.

Telnet client says : connecting to 192.168.1.101:23...

And it stays that way.

EDIT : seems I can not even ping to this host.

But there is no firewall or selinux on this host ??

But can not even ping this host.

But I can post this message to this forum from this host.

It could be a routing problem in your switches / routers, what is your network connection between the clients you are trying with?

sachin.davra · 01-20-2014, 07:52 AM

First you will have to ping ftp server from client. only then try to access ftp from that client.

jonaskellens · 01-20-2014, 08:02 AM

Sometimes I can ping the client, and then 10 seconds later I can no longer ping the client.

I have now switched to LAN in stead of WLAN on my Fedora 19, and now it seems I have more stability in ping and ftp logon results !

Problem thus is situated in the WLAN of Fedora 19.

Now are you able to use ftp from client in LAN?

markush · 01-20-2014, 08:26 AM

Hi,

you could use nmap and find out if the port for sftp is open:

Code:

nmap -p 115 192.168.1.101

should give you an answer. You can also scan all (wellknown) Ports with

Code:

nmap -sV 192.168.1.101

to check the server for open ports. Note that you can use the commands from both, server or client.

Yes, I can ping and use ftp.

Sometimes it still fails and then I switch from LAN to WLAN or from WLAN to LAN, and then it work again for some time.

I guess Fedora 19 is not very stable...

when you are not able to connect via ftp, try to ping server. if you are able to ping then you should be able to connect through ftp, if not then first you will have to troubleshoot ping problem.

SAbhi · 01-21-2014, 02:10 AM

well i watched it all over and saw every time you wrote its not even pinging or not able to use ftp while it was before, did you checked the logs to see what they says about it ?
