what ftp server is running
 
in my RHEL 4 server , I want to know what ftp server is running but can't find it.

I tried "ps -ef |grep ftp" but no output , chkconfig --list |grep ftp also no output related to ftp , /etc/rc.d/init.d can't find ftp service , ftp localhost is not allow .

when use FileZilla to connect it , it is ok , the ftp should be running , I tried to use "ps -ef |grep ftp" , it pops the following output , would advise what ftp server is running in server ? thanks

Code:
edp 11027 11026  0 12:39 ?        00:00:00 tcsh -c /usr/libexec/openssh/sftp-server
edp 11037 11027  0 12:39 ?        00:00:00 /usr/libexec/openssh/sftp-server
user  11050  7747  0 12:48 pts/2    00:00:00 grep ftp

probably netstat -ap will help

Not sure this applies to RHEL 4, but if it is handled by inetd look in /etc/inetd.conf and see what ftp line is enabled.

thanks reply,

tried run netstat -ap , but no ftp service

Just another guess, but try these...

Code:
service vsftpd status

service proftpd status
...see if there are any volunteers.

And still guessing vsftpd, you might open a session and look in...

Code:
tail /var/log/vsftpd.log
...OR...
tail /var/log/xferlog
...to see if it is there, or other recent timestamped messages.

In fact

How did you check that?

Bruce783 04-14-2015 03:02 AM
Post the output from...

Code:
netstat -tlnp | grep 21
This will determine what TCP service is listening on port 21. You can use this output to determine if you have a stand-alone FTP server running or if the FTP server is wrapped around something else.

This sftp-server comes bundled with sshd.

Else you could check your package list. rpm -qa and grep that for ftp

As other already suggested but putting another possible way of using netstat:

Code:
netstat -ptan | grep LIST
Will show you all the services which are running and listening on which port. Should be able to get you the name of the application / daemon.

FTP port == 21
SFTP port == 22

Madhu Desai 04-14-2015 10:21 AM
Code:
$ sudo nmap -sV localhost

PORT  STATE SERVICE VERSION
21/tcp open  ftp    vsftpd 3.0.2
22/tcp open  ssh    OpenSSH 6.8 (protocol 2.0)
Service Info: OS: Unix

$ netstat -tan | grep :21
tcp        0      0 0.0.0.0:21              0.0.0.0:*              LISTEN

Or the port is forwarded to another server running ftp service.
check iptables for rules.
Code:
iptables -L

Looks like a restricted sftp shell.
Look in /etc/ssh/sshd_config for
Subsystem sftp /usr/lib/openssh/sftp-server vs.
#Subsystem sftp /usr/lib/openssh/sftp-server

#rpm -qa |grep ftp
lftp-3.0.6-8.el4
ftp-0.17-23.el4_6.1

does it mean lftp server is using ?
