Port 21

Re: Port 21

Use port #4687 - change it in the Network Scanner Tool tab for System Options.

I need to change the port to higher than #4687?

Re: Port 21

Just let the IT guys know that by shutting down port 21 and opening another port is NOT going to solve the problem of viruses. It's kind of like drilling a hole in a bucket, saying there is water come out of that now, patching the hole up and then drilling another one right next to it.

If they are that worries about port 21, create an exception that says traffic on port 21 can only come from this IP address and use the IP address of the copier.

I myself am an IT person and I use FTP on its assigned port of 21 all the time. If I were to get a virus through on that port, then I would look at tightening the security around that port.

Thank you again for your reply,i will try to talk to the IT guy,because we have 20 unit of ar-m350/450 on the plant,and hope that he will listen to our advice.
Other than this, can we use scan to email option on this machine?

Re: Port 21

Thank you and sorry for the late reply.
Need to make some correction on this issue.Is not AV problem,is the port problem.
The IT guy from the factory say that the two port 20 and 21 got the virus issue.So yesterday they totaly close down the two port causing the scanner cannot scan.And they push back the issue to us and wanted us to reassign another port for them.
I need help and your expertise to guide me.
1)Can we change the port ?
2)Ask them to assign another port number?
3)Where we can change the port?From sharpdesk destination control?
Thank you .

Re: Port 21

Create an exception in the antivirus firewall.

Antivirus patterns as such won't block ports, but the firewalls the are installed along side some AV software will.

What AV are you using?

Does the machine scan when the AV is disabled?

Linuxxpwin is spot on the money in that certain ports are assigned to certain protocols. Port 25 that you thought about changing the FTP service to is assigned to SMTP (Outbound email or Simple Mail Transfer Protocol) and would cause issues with that PC sending email.

Fix the problem, don't create messy work arounds.

Re: Port 21

Hi all, need info and help.
Because anti virus block port 21 for ftp, causing the scanner cannot use ,can we change to port like port 25 or other?

Thank you ina dvance.

ports are assigned to certain things with a piece of hardware: port 21 is assigned to FTP
port 25 is assigned to SMTP (Mail)
pop3 on 110 (mail)

and so on, what you can try is to give specific information on your firewall to allow connections from an assigned IP Addess or addresses. or maybe depending on the firewall pgm you are using you can give permission to the program wanting to use the port.

if you reassign a port make sure it does not conflict with something else, or stop another service from running
