Example: ChatGPT Hallucination
The question: "Where is the 16 group limit set in NFS?"
Initial answer:
The 16 group limit in NFS is set by the RPC layer rather than NFS itself. Specifically, the limit is enforced by the Remote Procedure Call (RPC) authentication protocol, particularly in AUTH_UNIX (AUTH_SYS) authentication.
Where It Is Defined:
The RPC call structure allocates a fixed size for user credential data, including group memberships.
The traditional AUTH_SYS authentication (formerly AUTH_UNIX) in NFS limits the number of supplementary groups a user can belong to 16 because of the fixed-size credential structure.
Where It Is Implemented:
Linux Kernel (net/sunrpc/auth_unix.c)
In Linux, the limit is enforced in the SunRPC subsystem of the kernel, particularly in the handling of AUTH_SYS credentials.
glibc & libtirpc
Historically, the limit was enforced by glibc's RPC implementation, but newer systems use libtirpc, which maintains the same behavior.
NFS Daemons (rpc.mountd, nfsd)
The NFS server uses the group list provided by the RPC authentication layer, so it inherits this limit.
Workarounds:
Use Kerberos (AUTH_GSS): Switching to Kerberos-based NFS authentication (AUTH_GSS) removes the 16-group restriction because Kerberos handles groups differently.
Increase the limit with NFSv4 and --manage-gids: Some NFS implementations provide an option like --manage-gids in rpc.mountd, allowing the server to look up group memberships itself, bypassing the limit.
Would you like details on configuring these workarounds?
The follow up question: "Is this rpc_init_authunix the structure and where is the code that puts the GIDs in it?"
Yes, rpc_init_authunix initializes the AUTH_UNIX (AUTH_SYS) authentication structure in the Linux kernel's RPC subsystem. However, the actual setting of the supplementary group IDs (GIDs) happens in the process of encoding RPC credentials, specifically in auth_unix.c.
Where the GIDs Are Set in the Kernel:
The code responsible for filling in the group IDs is in net/sunrpc/auth_unix.c. The key function is:
1. auth_unix_encode()
This function encodes the AUTH_UNIX credentials, including the GID list:
static int auth_unix_encode(struct rpc_auth *auth, struct xdr_stream *xdr, struct rpc_cred *cred) { struct auth_unix_cred *unix_cred = container_of(cred, struct auth_unix_cred, cred); struct xdr_buf *buf = xdr->buf; __be32 *p; int i; p = xdr_reserve_space(xdr, (8 + unix_cred->auc_len) * 4); if (!p) return -EMSGSIZE; *p++ = htonl(AUTH_UNIX); *p++ = htonl(unix_cred->auc_time); *p++ = htonl(unix_cred->auc_uid); *p++ = htonl(unix_cred->auc_gid); *p++ = htonl(unix_cred->auc_len); for (i = 0; i < unix_cred->auc_len; i++) *p++ = htonl(unix_cred->auc_gids[i]); // This fills in the GID list return 0; }
2. auth_unix_cred Structure
The structure storing the GIDs:
struct auth_unix_cred { struct rpc_cred cred; unsigned int auc_time; kuid_t auc_uid; kgid_t auc_gid; unsigned intauc_len; // Number of groups kgid_t auc_gids[RPCSVC_MAXGROUPS]; // The GID list };
struct auth_unix_cred { struct rpc_cred cred; unsigned int auc_time; kuid_t auc_uid; kgid_t auc_gid; unsigned int auc_len; // Number of groups kgid_t auc_gids[RPCSVC_MAXGROUPS]; // The GID list };
The limit of 16 groups is typically defined as RPCSVC_MAXGROUPS (#define RPCSVC_MAXGROUPS 16).
Where This Code is Used:
When an NFS client makes an RPC call, it uses AUTH_UNIX authentication.
The kernel packs the UID, primary GID, and up to 16 supplementary GIDs into the RPC request.
The NFS server decodes this credential and enforces the group limit.
Would you like details on modifying this limit in the kernel or using alternative authentication methods?
I then provided it with the auth_unix.c source code and asked it if the code was in the source provided? It then finally identifies the correct source. The functions that it lists in its own generated answers don't exist.
Now, if you had asked a smaller model this same question chances are it would be totally wrong–so ChatGPT did better than that. However, when it got to the details–it was still wrong. The answer looks convincing–and if you are trying to understand what is going on–you could be fooled. Only by verifying and asking again and again can you be sure you get the right answer.
So, the next time you feel the urge to just trust ChatGPT output; remember–it may well be hallucinating and it may not be obvious depending on your knowledge level in the area.

Debian gui nfs manager

#Debian gui nfs manager how to#
#Debian gui nfs manager install#
After adding the server, you can use it for storage for your deployments. Within Rancher, add the NFS server as a storage volume and/or storage class. Result: Your NFS server is configured to be used for storage with your Rancher nodes. For example, the following command opens port 2049: sudo ufw allow 2049 the graphical desktop (window manager), the Internet, version control syst. Open the ports that the previous command outputs. When I started with Linux, there was a user-space nfs server available. To find out what ports NFS is using, enter the following command: rpcinfo -p | grep nfs Update the NFS table by entering the following command: exportfs -ra Tip: You can replace the IP addresses with a subnet. nfs (rw,sync,no_subtree_check) (rw,sync,no_subtree_check) (rw,sync,no_subtree_check) Follow each address and its accompanying parameters with a single space that is a delimiter. Add an entry for each IP address in your cluster.
Open /etc/exports using your text editor of choice.Īdd the path of the /nfs folder that you created in step 3, along with the IP addresses of your cluster nodes.
This table sets the directory paths on your NFS server that are exposed to the nodes that will use the server for storage.
The chown nobody:nogroup /nfs parameter allows all access to the storage directory.Ĭreate an NFS exports table.
The -p /nfs parameter creates a directory named nfs at root.
mkdir -p /nfs & chown nobody:nogroup /nfs Your Debian server is now ready to start serving files, and you shouldn’t have any trouble setting up the rest of your client machines. Modify the command if you’d like to keep storage at a different directory.
#Debian gui nfs manager install#
Using a remote Terminal connection, log into the Ubuntu server that you intend to use for NFS storage.Įnter the following command: sudo apt-get install nfs-kernel-serverĮnter the command below, which sets the directory used for storage, along with user access rights. Recommended: To simplify the process of managing firewall rules, use NFSv4.
#Debian gui nfs manager how to#
For official instruction on how to create an NFS server using another Linux distro, consult the distro’s documentation. This procedure demonstrates how to set up an NFS server using Ubuntu, although you should be able to use these instructions for other Linux distros (e.g. Instead, skip the rest of this procedure and complete adding storage. If you already have an NFS share, you don’t need to provision a new NFS server to use the NFS volume plugin within Rancher. I'd really like the RasPi to boot up and show me the NFS files when I open the file explorer.Before you can use the NFS storage volume plug-in with Rancher deployments, you need to provision an NFS server. And they appear each time thereafter when I open the file explorer.ĭoes anyone know what's going on? Why must the file explorer be manually refreshed the first time it's opened? If your system still has gksu (Ubuntu 16.04 and higher, Linux Mint 18.x and higher, Debian Stretch or sid-debports), you can use the following command to run the Simple NFS GUI: gksu SimpleNFSGUI For Ubuntu 18. If I then return to the file explorer and press F5, the files appear. Open in Terminal - An ls command shows all the files. If I right-click on /mnt/mike and choose from the options, I get: Clearly fthe fstab entries are OK.īut when I open the GUI file explorer and navigate to /mnt/mike, I see. If I then type ls /mnt/mike, I see the expected files on the server. I can mount the shares in a terminal with sudo mount /mnt/mike, etc. I can work around that with commands (and a sleep command if necessary) in /etc/rc.local. OK, maybe the network is not up when fstab is read. When the RasPi boots, these shares are not mounted through fstab. On my RasPI 3B, /etc/fstab contains a line like this: linux:/home/mike/share /mnt/mike nfs nolock,rw,bg 0 0 for each of the three shares. It exports several directories, and I can successfully mount them on two other Linux boxes, so I have a fair (not expert) idea of how NFS works. I have a server running Debian Linux on our household network. I'm having an odd problem mounting NFS shares and seeing them in the GUI file explorer.

雜論nfs掛載可能的坑
youtuber安啾以倉鼠玩具成名
基本上她的開箱跟手作企劃最後結局都以失敗居多,但大家還是看得很開心
因為很療癒吧? 看著這廢材一直搞砸,自我優越感油然而生,簡直多到爆棚….
我也踩過很多坑,寫在這邊的每一個都是血淋淋的慘痛經驗
近期最大的坑就是nfs
環境是兩台ftp主機共同存取一個nfs目錄
觀察到的現象是ftp會失敗,但sftp可以。一段時間後共用目錄會失聯,重新下指令mount也沒用,一定要重開機
過程懷疑了很多事情,例如網路port的LACP、firewall的session timeout
我們一直覺得跟firewall有關,但也說不清是什麼問題
存取netapp ok,換成redhat內建的nfs就不行,感覺跟linux也有關
在存取netapp的往日時光,開個111跟2049就好
為什麼 redhat就不行呢? 因為redhat 的nfs port會跳動
Redhat官網說要編輯/etc/sysconfig/nfs
# Port rquotad should listen on.
RQUOTAD_PORT=875
# TCP port rpc.lockd should listen on.
LOCKD_TCPPORT=32803
# UDP port rpc.lockd should listen on.
LOCKD_UDPPORT=32769
# Port rpc.mountd should listen on.
MOUNTD_PORT=892
# Port rpc.statd should listen on.
STATD_PORT=662
我覺得主要是LOCKD_TCPPORT LOCKD_UDPPORT要固定住,其它的不固定也可以動,但不固定會有什麼影響?不知道…
我去看了一下netapp的文件,它還真的有固定
Clustered Data ONTAP: 111 TCP/UDP portmapper 2049 TCP/UDP nfsd 635 TCP/UDP mountd 4045 TCP/UDP nlockmgr 4046 TCP/UDP status Data ONTAP 7 Mode: 111 TCP/UDP portmapper 2049 TCP/UDP nfsd 4046 TCP/UDP mountd 4045 TCP/UDP nlockmgr 4047 TCP/UDP status
我們最近還用了一個黑箱般的hpe 3par file persona
真的是超雷的設備,到處都是坑
建置過程隨便就踩到坑,跌跌撞撞的一路走過來苦不堪言
在文件裡是這麼交代所使用的port,看起來也是固定的
NFS VFS IP 111 UDP/TCP rpcbind/sunrpc Incoming
NFS VFS IP 662 UDP/TCP NFS statd Incoming
NFS VFS IP 875 UDP/TCP NFS quota Incoming
NFS VFS IP 892 UDP/TCP NFS mountd Incoming
NFS VFS IP 2020 UDP/TCP NFS stat_outgoing Outbound
NFS VFS IP 2049 UDP/TCP NFSv4 Incoming
NFS VFS IP 32769 UDP NFS Lock_Manager Incoming
NFS VFS IP 32803 TCP NFS Lock_Manager Incoming
我只是覺得很奇妙 111 2049這種可能是大家講好的port,所以一樣
32769 32803這種在redhat文件中範例出現的數字, HPE 3par有需要照抄嗎?
去google隨便查詢一下就會找到一堆netapp的文章
3par根本找不到一般人的文章,只有官宣,某種程度上就代表沒什麼人在用
也不是多人用就好,沒人用的就不好
但照常理來說如果好用就會越來很多人用,不好用就不會再用,甚至口耳相傳的勸朋友不要用
結論我也不寫了,大家心照不宣

Design and Implementation of the FreeBSD Operating System, The, 2/e - Marshall Kirk McKusick, George V. Neville-Neil & Robert N.M. Watson
Design and Implementation of the FreeBSD Operating System, The, 2/e Marshall Kirk McKusick, George V. Neville-Neil & Robert N.M. Watson Genre: Operating Systems Price: $54.99 Publish Date: September 5, 2014 Publisher: Pearson Education Seller: Pearson Education Inc. The most complete, authoritative technical guide to the FreeBSD kernel’s internal structure has now been extensively updated to cover all major improvements between Versions 5 and 11. Approximately one-third of this edition’s content is completely new, and another one-third has been extensively rewritten. Three long-time FreeBSD project leaders begin with a concise overview of the FreeBSD kernel’s current design and implementation. Next, they cover the FreeBSD kernel from the system-call level down–from the interface to the kernel to the hardware. Explaining key design decisions, they detail the concepts, data structures, and algorithms used in implementing each significant system facility, including process management, security, virtual memory, the I/O system, filesystems, socket IPC, and networking. This Second Edition • Explains highly scalable and lightweight virtualization using FreeBSD jails, and virtual-machine acceleration with Xen and Virtio device paravirtualization • Describes new security features such as Capsicum sandboxing and GELI cryptographic disk protection • Fully covers NFSv4 and Open Solaris ZFS support • Introduces FreeBSD’s enhanced volume management and new journaled soft updates • Explains DTrace’s fine-grained process debugging/profiling • Reflects major improvements to networking, wireless, and USB support Readers can use this guide as both a working reference and an in-depth study of a leading contemporary, portable, open source operating system. Technical and sales support professionals will discover both FreeBSD’s capabilities and its limitations. Applications developers will learn how to effectively and efficiently interface with it; system administrators will learn how to maintain, tune, and configure it; and systems programmers will learn how to extend, enhance, and interface with it. Marshall Kirk McKusick writes, consults, and teaches classes on UNIX- and BSD-related subjects. While at the University of California, Berkeley, he implemented the 4.2BSD fast filesystem. He was research computer scientist at the Berkeley Computer Systems Research Group (CSRG), overseeing development and release of 4.3BSD and 4.4BSD. He is a FreeBSD Foundation board member and a long-time FreeBSD committer. Twice president of the Usenix Association, he is also a member of ACM, IEEE, and AAAS. George V. Neville-Neil hacks, writes, teaches, and consults on security, networking, and operating systems. A FreeBSD Foundation board member, he served on the FreeBSD Core Team for four years. Since 2004, he has written the “Kode Vicious” column for Queue and Communications of the ACM . He is vice chair of ACM’s Practitioner Board and a member of Usenix Association, ACM, IEEE, and AAAS.

如何保证NFS文件锁的一致性?
阿里妹导读:在存储系统中, NFS(Network File System,即网络文件系统)是一个重要的概念,已成为兼容POSIX语义的分布式文件系统的基础。它允许在多个主机之间共享公共文件系统,并提供数据共享的优势,从而最小化所需的存储空间。本文将通过分析NFS文件锁状态视图一致性的原理,帮助大家理解NFS的一致性设计思路。
文件锁
文件锁是文件系统的最基本特性之一,应用程序借助文件锁可以控制其他应用对文件的并发访问。NFS作为类UNIX系统的标准网络文件系统,在发展过程中逐步地原生地支持了文件锁(从NFSv4开始)。NFS从上个世界80年代诞生至今,共发布了3个版本:NFSv2、NFSv3、NFSv4。
NFSv4最大的变化是有“状态”了。某些操作需要服务端维持相关状态,如文件锁,例如客户端申请了文件锁,服务端就需要维护该文件锁的状态,否则和其他客户端冲突的访问就无法检测。如果是NFSv3就需要NLM协助才能实现文件锁功能,但是有的时候两者配合不够协调就会容易出错。而NFSv4设计成了一种有状态的协议,自身就可以实现文件锁功能,也就不需要NLM协议了。

Some file operations on /public were slow
Due to a NFS bug, some operations on the /public filesystem -- in particular, recursive removal of directories -- were very slow. We have now applied a workaround. Please report any further issues to the sysadmins.
(Specifically, we encountered an issue whereby NFSv4 delegations would become out-of-sync between our new storage server and the servers that users log into, which act as NFS clients. NFS clients would successfully obtain a delegation when opening a file or directory, but would then disavow all knowledge when the server asked them to hand back the delegated file. This led to an 87-second delay on each file involved in some operations whilst the server gave up waiting for the client to respond correctly. We have mitigated against this bug by disabling delegations entirely; this may reduce performance slightly in general but will prevent very long delays when the bug is triggered.)

Smbitinabox causes 3,144 counties files in USA to be exposed and accessed worldwide including foreign country cities
The following links shows over 3,144 exposed files on Google to access from small to large corporations that will allow Cyber Criminals to extract all exposed data from forbidden hidden files. These files are sensitive financial data, personal records, sensitive data, and highly confidential information. Malware programs are being written to extract these 3,144 counties that host servers to extract exposed files and steal data.
The links to the 3,144 cities exposed files can be found below:
The exposed files are over 2 Million confidential files that can be accessed on Google at the following link ( Over 2 Million exposed files worldwide)(2019). Most file systems have methods to assign permissions or access rights to specific users and groups of users. These permissions control the ability of the users to view, change, navigate, and execute the contents of the file system. The way it looks the wrong commands was applied to these file systems, which employees was given administrator access to secure these files, but did not do.costTwo types of permissions are very widely used: traditional Unix permissions date back many decades to the earliest days of Unix. They are universally available on all Unix and Linux derived platforms. Access Control Lists (ACLs) are more recent in origin and are universally used on Microsoft Windows based file systems where the file system supports user permissions (mainly NTFS and ReFS), and are also now commonly used and widely available in most common Unix and Linux based systems, although not necessarily all. They are generally capable of far more detailed fine-tuning of permissions than the traditional Unix permissions, and permit a system of access control which traditional ACLs cannot provide. On Unix and Linux based systems, the standard type of ACL is that defined by the POSIX standard (POSIX ACLs) but other variants exist such as NFS v3 and v4 ACLs, which work slightly differently (NFSv3 ACLs or NFSv4 ACLs).Where multiple systems are available within the same operating system, there is usually a way to specify which will be used for any given file system, and how the system should handle attempts to access or modify permissions that are controlled by one of these, using commands designed for another. The usual solution is to ensure at least some degree of awareness and inter-operability between the different commands and methods. The cost on securing these files will be over $100 Billion as Billions of dollars are already lost because Cyber Criminals can download and extract the financial, hospital data, businesses sensitive data, large corporations data, and many more sensitive data that can be extracted. The SMBITINABOX can be founded all over Google that is scattered Worldwide on popular networks which allow Cyber Criminals to download any file they want at the following link ( SMBITINABOX scattered all over Google for any Cyber Criminal to access )(2019).

Encrypting NFSv4 with Stunnel TLS
NFS clients and servers push file traffic over clear-text connections in the default configuration, which is incompatible with sensitive data. TLS can wrap this traffic, finally bringing protocol security. Before you use your cloud provider's NFS tools, review all of your NFS usage and secure it where necessary.
