![]() # you have loaded a kernel SCSI driver for your SCSI adapter. If you expected something different, make sure that # scanner is powered up and properly connected to your computer. # result is different from what you expected, first make sure your # sane-find-scanner will now attempt to detect your scanner. Which came with this software (README, FAQ, $ sane-find-scanner If you were expecting something different,Ĭheck that the scanner is plugged in, turned on and detected by the Perhaps you would prefer the range 192.168.1.0 - 192.168.1.63? I'll leave it up to you how to figure it out.įollow your steps step by step after the completion of the following tips, I should do? Therefore, the slash notation for that range is 192.168.1.0/27. Which means we want the first 27 bits to be unchanged (remember, the total bits in an IPv4 address is 32. So, after comparing the two, you can see that the difference between them is the last 5 bits. So you say you want a range of IP between 192.168.1.2 and 192.168.1.33 With the "slash notation" (this is what the 192./24 notation is called) this is impossible because of the binary nature of the IP address which I hope you now understand. Which will give us a range from 192.168.0.0 to 192.168.1.255 (why "255"? Because 255 is highest number you can make in binary with 8 bits: 11111111) So when we say "the first 24 bits of the address are unchanged", what that means is that the last one byte of the address can have any value (remember the IPv4 address is 4 bytes long), i.e. The "192.168.17.42" is just used by humans because it's easier to read and remember. ![]() When computers talk to each other on the internet they actually use the binary representation. So if we see an address like 192.168.17.42, in bits representation (which is binary representation) it would be: 11000000 10101000 00010001 00101010 (notice instead of dots I used spaces to separate the bytes). ![]() What do bits have to do with this? Well, you see, an IPv4 address consists of 32 bits or 4 bytes (1 byte = 8 bits). The "/24" means "the first 24 bits of the address are the unchanged". So when we talk about IP ranges in the format like 192.168.1.0/24, most people think it means all IPs from 192.168.1.0 to 192.168.1.24 It only happens when it cannot connect to the host and I try to close the program. If I have no error during the initiating the ScanImage program, I can close it just fine with out the memory error. I have adjusted my DHCP server so that my Windows 7 PC will always get the same IP.īut I still like to know how can I set nf so it would accept a range of IP addresses? I check my IP address and added it again and it work again. I knew that the Windows 7 IP must be listed because when I reboot my Windows 7 PC and it got a new IP address, I cannot connect to the scanner again. So I added my Windows 7 IP address on the list, and it worked. I thought it meant that it is a range of IP Address between 2 and 33, but I think I was wrong.

The first thing we need to do is to compile the Epson iscan drivers. Now you can reboot the Raspberry Pi (sudo reboot). If you do not edit this file, SaneTwain will hang when contacting your Raspberry Pi scanner server. You can also explicitly specify single IPs (in my case I just added 192.168.0.20, which is the IP of my main PC). ![]() Please adjust the subnet specification 192.168.1.0/24 to your network architecture. # The hostname matching is not case-sensitive. ![]()
