Samba login failure windows 7

If this machine will be configured as a BDC a secondary logon server , you must set this to 'no'; otherwise, the default behavior is recommended. Maximum number of usershare. Change the next parameter to 'no' if you want to be able to write to them. If you want to create dirs. You may need to replace 'lpadmin' with the name of the group your admin users are members of. Improve this question. I had the problem that the windows username was identical to the unix username on the machine running samba.

Samba then imported the unix username and therefor always asked for the password. Also see superuser. The strange thing is that I can't connect with windows systems A , but it works without a problem connecting with windows system B.

This disables any security. Guest access with write permissions. Basically I had to run the command: sudo smbpasswd -a pi to create the pi samba user. I say Reinstate Monica 3, 7 7 gold badges 23 23 silver badges 50 50 bronze badges. T Mai T Mai 41 1 1 bronze badge.

This should be avoided at all costs due to numerous exploits. Don't do it! I have a media player that only does SMB1 and I will not throw it away and there is no firmware upgrade.

I understand the wish to keep old working hardware in use but the security ramifications are severe and you should completely isolate shares with SMB1 from the rest of the network and the internet. At this point you might as well dump everything on an external drive and directly attach it to the client. It only takes a minute to sign up. Connect and share knowledge within a single location that is structured and easy to search.

Also, this box can connect via smbclient to other Windows boxes that this client has. Make sure your workgroup and security settings are properly set. If you are working with a a computer as part of a domain, authentication requests are first passed through your domain controller, so make sure you have something similiar to:.

It would be nice if that were clear in the documentation I found. I was having the same problem with smbclient, and I noticed that it went away when I manually selected the "Just Enable File Sharing" option on the File Sharing dialog you get after manually right-clicking on the folder you want to share. In some Windows machines like Windows XP you need to add this to permit remote sharing for non guest users:. This can be helpful for troubleshooting only , I would not recommend keeping it off for everyday use.

If so, it might not be claiming names; this means that Samba is not providing the browsing service—a configuration problem.

If that is the case, make sure that smb. Double back to Chapter 3 and ensure that you have a client installed that is listening to the network. If nmblookup -B See your network manager. This time we are testing the ability of programs such as nmbd to use broadcast. It's essentially a connectivity test, done via a broadcast to the default broadcast address.

Samba might not catch all the responses in the short time it listens, so you won't always see all the SMB clients on the network. However, you should see most of them:. If this doesn't give at least the client address you previously tested, the default broadcast address is wrong. Try nmblookup -B If this draws responses, the broadcast address you've been using before is wrong.

Troubleshooting these is discussed in Section If the address You should try to diagnose this step with a server and client on the same subnet, but if you can't, you can try specifying the remote subnet's broadcast address with -B. Finding that address is discussed in Section The -B option will work if your router supports directed broadcasts; if it doesn't, you might be forced to test with a client on the same network.

You should get back a list of available shares on the server. If this works, continue with the later section Section If you get Network name not found for the name you just tested in the earlier section, Section Double-check this by running nmblookup on the client; if it works and net view doesn't, the client is at fault. If you get You do not have the necessary access rights , or This server is not configured to list shared resources , either your guest account is misconfigured see the earlier section, Section These problems should have been detected by the smbclient tests starting in the earlier section, Section If you get The specified computer is not receiving requests , you have misspelled the name, the system is unreachable by broadcast tested in the earlier section, Section If you get Bad password error , you're probably encountering the Microsoft-encrypted password problem, as discussed earlier in this chapter and in Chapter 9 , with its corrections.

Your Samba server should appear in the browse list of your local workgroup. You should be able to double-click the name of the server to get a list of shares. If you get an Invalid password error, it's most likely the encryption problem again. If you receive an Unable to browse the network error, one of the following has occurred:. You have looked too soon, before the broadcasts and updates have completed. Wait 30 seconds and try again. There is no browse master.

If you've made it this far and the problem is not yet solved, either the problem is one we've not yet seen, or it is a problem related to a topic we have already covered, and further analysis is required. Name resolution is often related to difficulties with Samba, so we cover it in more detail in the next sections.

If you know your problem is not related to name resolution, skip to the Section This section looks at simple troubleshooting of all the name services you'll encounter, but only for the common problems that affect Samba.

Each kind of system has a different preference:. Don't assume that if a different program's name service works, the SMB client program's name service will! You'll have to look at your notes and the actual systems to see which is in use. You might need to check there to see what you've actually turned on.

If it does, you're using DNS. You might be using the others as well, though. You'll need to check for NIS and combinations of services. These are the name services to use, in order, with optional extra material in square brackets. If the client and server differ, the first thing to do is to get them in sync. If you can't get all the systems to use the same services, you'll have to check the server and the client carefully for the same data.

You can also make use of the -R resolve order option for smbclient. If you want to troubleshoot WINS, for example, you'd say:. In the following sections, we use the term long name for a fully qualified domain name FQDN , such as server. Run nslookup name. If this fails, look for a resolv. Try the following:. These are the addresses of your DNS servers. Ping each server address you find. If this fails for one, suspect the system. If it fails for each, suspect your network.

Retry the lookup using the full domain name e. If results differ, skip to the next section. Run nmblookup -S server. This reports everything broadcast has registered for the name. In our example, it looks like this:. You should also see your workgroup mentioned one or more times. The numbers in angle brackets in the previous output identify NetBIOS names as being workgroups, workstations, and file users of the messenger service, master browsers, domain master browsers, domain controllers, and a plethora of others.

Try ypmatch name hosts. If this fails, NIS is down. Find out the NIS server's name by running ypwhich , and ping the system to see if it's accessible.

Each line should have an IP number and one or more names, the primary name first, then any optional aliases. An example follows:. On Unix, localhost should always be It has a format similar to hosts files, but it does not support long-form domain names e. There is usually an lmhosts. Where the long FQDN form of a hostname works but the short name doesn't for example, client. This usually indicates that there is no default domain in which to look up the short names.

One or the other might need to be present to make short names usable; which one depends on the vendor and version of the DNS resolver. Try the command ypmatch hostname hosts.

If you don't get a match, your tables don't include short names. Speak to your network manager; short names might be missing by accident or might be unsupported as a matter of policy.

Some sites don't ever use ambiguous short names. Try nismatch hostname hosts , and treat failure exactly as with NIS. Avoid, if you can, short names as primary names the first one on a line. Have them as aliases if your system permits. On the other hand, if the short form of the name works and the long form doesn't, consider the following:. Optionally, consider DNS. If you can use ypmatch to look up the short form but not the long, consider adding the long form to the table as at least an alias.

Same as NIS, except you use nismatch instead of ypmatch to look up names. Add the long name as at least an alias, and preferably as the primary form.

Also consider using DNS if it's practical. This is normal. Test the same name with the nslookup command on the system that is slow client or server. If nslookup is also slow, you have a DNS problem. If it's slower on a client, you might have too many protocols bound to the Ethernet card. This is especially important on Windows 95, which is particularly sensitive to excess protocols. Test the client using nmblookup ; if it's faster, you probably have the protocols problem as mentioned in the previous item.

The hosts files, if of reasonable size, are always fast. You probably have the protocols problem mentioned previously under DNS. There is probably no record for localhost.

A Arrange to add one, as well as a reverse entry, 1. A number of common problems are caused by incorrect routing of Internet addresses or by the incorrect assignment of addresses. This section helps you determine what your addresses are. Using the netmask, it is possible to determine which addresses can be reached directly i. If the netmask is wrong, the systems will make one of two mistakes. One is to route local packets via a router, which is an expensive waste of time—it might work reasonably fast, it might run slowly, or it might fail utterly.

The second mistake is to fail to send packets from a remote system to the router, which will prevent them from being forwarded to the remote system. The netmask is a number like an IP address, with one-bits for the network part of an address and zero-bits for the host portion. If the mask is More common is For example, let's say your IP address is If your netmask happens to be In this case, the network parts are different, and the systems are on different networks:.

In this case, the network parts match, and so the two systems are on the same network:. Make sure the netmask in use on each system matches the structure of your network.

On every subnet, the netmask should be identical on each system. The broadcast address is a normal address, with the hosts part all one-bits. It means "all hosts on your network. The following table illustrates this:. In this example, the broadcast address on the There is also an old "universal" broadcast address, Routers are prohibited from forwarding these, but most systems on your local network will respond to broadcasts to this address.

A number of address ranges have been reserved for testing and for nonconnected networks; we use these for the examples in this book. If you don't have an address yet, feel free to use one of these to start.

They include one class A network, The domain example. If you're actually connecting to the Internet, you'll need to get an appropriate IP address and a domain name, probably through the same company that provides your connection.

If you haven't recorded your IP address, you can learn it through the ifconfig command on Unix or the ipconfig command on Windows. Check your manual pages for any options required by your brand of Unix. For example, ifconfig -a works on Solaris.

You should see output similar to the following:. One of the interfaces will be loopback in our examples, lo0 , and the other will be the regular IP interface. The flags should show that the interface is running, and Ethernet interfaces will also say they support broadcasts PPP interfaces don't. This was a simple scheme where each system had a unique character name and broadcast it on the LAN for everyone to know.

The usual mapping of domain names such as server. For example, corpvm1 along with vm1. A system with a different NetBIOS name and domain name is confusing when you're troubleshooting; we recommend that you try to avoid this wherever possible.

NetBIOS names are discoverable with smbclient :. Check in the smb. Try to list shares again, specifying -I and the IP address of the Samba server e. This overrides the name lookup and forces the packets to go to the IP address. If this works, there was a mismatch.

Try with -I and the full domain name of the server e. This tests the lookup of the domain name, using whatever scheme the Samba server uses e. If it fails, you have a name service problem.

You should reread the earlier section, Section If nothing is working so far, repeat the tests specifying -U username and -W workgroup , with the username and workgroup in uppercase, to make sure you're not being derailed by a user or workgroup mismatch.

If still nothing works and you had evidence of a name service problem, troubleshoot the name service see the earlier section, Section At some point during your work with Samba, you'll want to turn to online or printed resources for news, updates, and aid. It's OK to read the documentation. Nobody can see you, and we won't tell.

Usenet newsgroups have always been a great place to get advice on just about any topic. In the past few years, though, this vast pool of knowledge has developed something that has made it into an invaluable resource: a memory.

The primary newsgroup for Samba is comp. This should always be your first stop when there's a problem. However, the Windows box is incapable of returning your query, complaining about no memory, it seems. So how about we check the Windows machines and figure out if there's anything in the Event log there?

Event , srv: The server was unable to allocate from the system nonpaged pool because the server reached the configuration limit for nonpaged pool allocations. All right, now that you know what the problem is all about, you can go about the Web and get the necessary information.

Once you have the exact Event ID, the resolution is trivial. It turns out that the Windows box does not have enough memory to allocate to your requests, as silly as it sounds. Therefore, how do you resolve the Event ID ? You will need to open the registry editor and make two changes. No need to reboot or anything, the change will take place on the fly.

A three-year-old article by Alan Lamielle facing a similar issue with CIFS; there are several other discussions on Windows TechNet and Microsoft Answers, but this one offers the best information overall. All your shares are belong to anti-virus software - probably not. Fix Windows shares browsing issues - Ubuntu forums. I may come off as an angry, all-knowing nerd in this article, but that's exactly the point. Sometimes, problems are far simpler than they appear.

Rather than doubting your operational setup that has served you loyally all these years, you should immediately doubt the new changes added to the environment. Do not start editing configuration files, installing software and disabling services and components in a blind hope to get something going.

As this particular case illustrates, when faced with a stupid problem, so to speak, you should refrain from making too many changes that will only complicate the situation. Try using the command line if possible and reading system logs to get some kind of an error message or a code number.
