Sharp AR-M355N - Unable to access Web Settings via http://ip.address/

[drankinatty]

Guys, Gals,

I have a Sharp AR-M355N copies with the AR-FX12 fax expansion unit. In the past, I have been able to access the web interface, but now I can't. The network scanning works fine and I can ping the copier from the network. I can even ftp:// into the copier and see the /lp folder, but I cannot access the web settings with http://ip.address/ (in this case: http://192.168.7.20/ or just http://sharp/) (name resolution for sharp works fine on the network)

I am a bit bewildered by not being able to access the web settings. (primarily I can't change address book entries for email/ftp address, and I can't set the ftp user/pw access credentials without it)

Can I reset this somehow? I've turned the box on/off a number of times and I've changed the copier IP from dhcp to fixed IP and back. (dhcp server hands out 192.168.7.20 either way based on the copier MAC address)

What say the experts?

You can reset the NIC from the operation panel under the custom settings key in key operator mode. Access to the web interface does not require the HTTP:// before the ip address. Just clear the address bar completely and type the IP and it should allow you in.

Thanks Sharpie,

I have reset the NIC on a number of occasions. The problem is with the copiers response to http requests. In this case, it is like there are NO web interface files on the copier.

Do you know of anything that can be checked in admin key ops that would confirm if it is working? Maybe a sim code?

Sounds like you may have some type of network conflict. Under system settings go to list print, printer test page, nic page and you will get all of the setting information. Then I would unplug the copier and go to a computer and ping the address on the nic page and see what happens.

Good luck.

Maybe someone activated SSL.... Try login in using https://ip_adress/

Sounds like you have an IP conflict. Set the copier to DHCP/Dynamic and see what address it picks up. More than likely, something else on the network has taken the same IP that the Sharp was using earlier.

EDIT: Just noticed that you said you did the DHCP thing already. Check the rest of the TCP/IP settings to see if anything else on the network has changed.

hi
maybe new anti-virus been installed or fire wall settings been changed

To rule out firewall etc I occasionally use a Cat5 crossover cable from my laptop and connect it directly to the MFP. If you type in the static IP on your MFP an manually set your computer to another IP in the same range it should work.
If you can't see the web page, there must be something wrong with the NIC. Maybe next step is to upgrade firmware on NIC (if possible)
Most new laptop network cards have a crossover switch, so a standard Cat5 cable could work...

Hmm...

Bil,

That seems like what is occurring and what makes sense. For the life of me, I don't know how the conflict could occur, but the symptoms are right on the money. The dhcp server running on the network has a check to make sure the copier is the only device that can receive that IP:

# we want the copier/scanner to appear at a fixed address
host sharp {
hardware ethernet 08:00:1F:1F:C0:9D;
fixed-address 192.168.7.20;
}

Scanning from the copier to the network confirms that the copier 'sharp' does indeed have the IP 192.168.7.20:

Mon Mar 7 14:25:07 2011 [pid 2] CONNECT: Client "192.168.7.20"
Mon Mar 7 14:25:07 2011 [pid 1] [davidg] OK LOGIN: Client "192.168.7.20"
Mon Mar 7 14:25:09 2011 [pid 3] [davidg] OK UPLOAD: Client "192.168.7.20", "/home/samba/scans/david_20110307_145244.pdf", 54011 bytes, 22.89Kbyte/sec

However, there is still no web setting access to the copier with http or https:

[14:29 phoenix:/var/log] # lynx -dump http://192.168.7.20

Howerver, I can ftp:// into the copier just fine:

Connected to 192.168.7.20.
220 SHARP AR-M355N Ver 01.00.14 FTP server.

Remote system type is JC-CONNECT.
ftp> dir
200 PORT command Ok.
150 Open data connection.
total 0
d-w--w--w- 1 nobody nobody 0 Jan 1 1970 lp
226 Data connection closed.

So at least I know ftp is working to the JC-CONNECT part of the copier (whatever that is JetConnect something??)

I guess that only leaves some weird network conflict or http redirection that prevent me talking to the copier via http. I'll try shutting down servers and giving it another go.

If anybody else has thoughts on this, please do not hesitate to chime in. I'll try anything at this point

SOLVED!

No Conflict. Some nut had moved the http port to a high port (6658). So access to the web server was http://192.168.7.20:6658/

Sheesh...

Thank everyone for their input. It was indeed a bizarre issue :-)

Re: Sharp AR-M355N - Unable to access Web Settings via http://ip.address/

Having similar problem with a AR-M257. I hooked it up to my laptop and i am still unable to connect to the web interface. I assume the HTTP port change was a change made on the PC and not the MFP right. Any suggestion would be helpful.

Re: Sharp AR-M355N - Unable to access Web Settings via http://ip.address/

If you think the HTTP port has been moved, you can get a laptop, install Nmap (download at Download the Free Nmap Security Scanner for Linux/MAC/UNIX or Windows), connect your laptop directly to the copier and change your laptop's network settings to get it onto the copier's network, and run a port scan at the copier's IP address. (You'll want the direct connection to avoid any problems with firewalls and IDS/IPS appliances.)


This should be able to tell you whether the HTTP has moved from port 80.


The Nmap site has some pretty good documentation and it is free.

If the copier's port 80 is still accepting HTTP, then you could also download a packet sniffer (like Wireshark, it's free too) and, while capturing the traffic on the appropriate network interface, try to open up the copier's webpage. You may be able to determine what the issue is that way. This is a very granular look at the traffic and you may need someone to analyze the packet capture for you.

Good luck!
