Hello, I was having few issues on my linux box, I am getting this error whenever I tried to mount a share on a client linux host. Code: # mount -t nfs 10.10.4.150. Smb.conf(5) - Linux man page Name. The smb.conf file is a configuration file for the Samba suite. The ftpd, rlogind, rexecd, rshd, talkd, telnetd, and uucpd daemons are started by default. The tftpd, fingerd, and comsat daemons are not started by default. Table 6- 3 shows the rough equivalents to non- Solaris. Correspondence of Solaris and non- Solaris mount components. List of filesystems. List of mounted filesystems. RPC program number to network address mapper. NFS clients can mount any filesystem, or part of a filesystem, that. NFS server. The filesystem can be.

There are. a few well- known and widely supported options, and others that are. NFS features or to integrate secure. As with everything else that is. Check the manual pages for. M), mount. However, pay particular attention to the. Chapter 1. 2, . The nosuid suboption is. Solaris, but perhaps it ought to be. Note that. server is the hostname of the NFS server. The. last two forms are used when mounting replicas. The option is not necessary. The. way to specify read- only is the ro suboption to. Suboptions can also be specified (without. The common. NFS mount suboptions are. If ro is specified, the filesystem. Use the ro option if. By. default, NFS mounts are not performed in the background, so. We'll discuss the. Note that. the bg option does not apply to the automounter. Chapter 9, . One area in which System V differs from 4. BSD systems is in the group identifier of newly created files. System. V will set the group identifier to the effective group identifier of. If the grpid option is set. BSD semantics are used, and so the group identifier is always. You can control this.

We will discuss it in more detail in Chapter 1. We will go into more detail in Chapter 1. Valid security modes are as specified in Section 6. We will go into more detail in Chapter 1. If the soft option is specified, an NFS. RPC call returns a timeout error if it fails the number of times. Once the protocol. If you are mounting multiple. NFS. The binding of the NFS protocol versions is per mount point and. NFS client/server pair. Note the NFS protocol version is. See the discussion of the. TCP is the commonly used.

By default. the mount command will select TCP over UDP if. TCP. Otherwise UDP will be used. As noted previously, the NFS protocol version is. You can have NFS Version. TCP and UDP (or just TCP, or just. UDP). Similarly, you can have NFS Version 3 clients that support TCP. UDP (or just TCP, or just UDP). This misconception arose because. Solaris 2. 5 introduced both NFS Version 3 and NFS over TCP at the. NFS mounts that previously used NFS Version 2 over. UDP now use NFS Version 3 over TCP. The retrans option is. TCP. This is because it is assumed. TCP protocol driver will do a better of job. TCP level retransmissions. Thus when using TCP, the RPC. The. timeo parameter varies the RPC timeout period. For example, in. /etc/vfstab, you could have. This option specifies the number of times to retry the mount attempt. For NFS Version 2, the maximum transfer size is 8. For NFS Version 3, the client and server. Solaris systems will by default negotiate a. If a server is down and a client is waiting for an RPC. RPC call hangs until the. With the. intr option, the user can use Unix signals (see. NFS RPC. calls and force the RPC layer to return an error. The. intr option is the default. The nointr. option will cause the NFS client to ignore Unix signals. The purpose behind this. We will discuss attribute caching and. NFS input/output in more detail in Chapter 7, . The quantity n is specified in seconds. The two options prefixed with acreg. The. actimeo option simply sets the minimum and. We will discuss attribute caching in more detail in Chapter 7, . Marketing managers for products that compete with NFS use. NFS is therefore a network bandwidth. The. reality is that the attribute timeouts are checked only whenever a.

Given that in. NFS Version 2, and to an even higher degree in NFS Version 3. NFS responses, attribute. This is to guarantee cache consistency. It can't be higher than 1. It can't be higher than one hour (3. Backgrounding mounts. The mount protocol used by clients is subject to the same RPC timeouts as individual NFS. RPC calls. When a client cannot mount an NFS filesystem during the. RPC execution time, it retries the RPC operation up to the. If. the bg mount option is used. If bg. is not specified, mount blocks waiting for the. The default value of 1. If you need the filesystem to run. Any. filesystem that is not critical to the system's operation can.

So what if you have. To cope, you will need to use the automounter (see Chapter 9, . If you have a power. Hard and soft mounts. The hard and soft mount. By default. all NFS filesystems are mounted hard, which. RPC call that times out will be retried indefinitely. This makes the NFS. An. NFS server that crashes looks like a disk that is very, very slow. If an NFS server goes down, the. Using. intr in conjunction with the.

You. should not use the soft option on any filesystem. Furthermore, because many applications do not check. NFS only guarantees the consistency of data. NFS filesystem was hard- mounted by the. Unless you really know what you are doing, neveruse the soft option. Resolving mount problems. There are several things that can go wrong when attempting to mount an NFS. The most obvious failure of mount is. You get the usual assortment of errors such as. NFS is not configured into the client's. The device in question is more of a. NFS vnode. operations. If the NFS client code is not in the kernel, this. We won't discuss how to build a kernel; check. NFS. But sometimes it means that the. Once the retransmission limit. The NFS client cannot tell the difference between. NFS RPC calls are not. If NFS clients begin printing . When the second client goes to reference the. NFS server can no longer find it on disk, and. If you get RPC. timeouts, then the remote host may have lost its portmapper service. Use ps to locate these processes. In this case, make sure that. NFS server, by checking the. On some systems (not Solaris), there might be a. RPC service number with the portmapper. Since the. inetd- spawned process is usually the second to. The NFS RPC daemons should be started from. Section 1. 5. 3, . You can only use. NFS to mount another system's local filesystem as one of your. NFS filesystems. You can't mount another system's. NFS- mounted filesystems. That is, if. /export/home/bob is local on. If a client attempts to mount a. Let's say NFS client marble has done. NFS server that exports. If a third system tries to mount. Too many levels of remote in path. You cannot nest NFS. There are two. practical sides to this restriction. Allowing multihop mounts would defeat the host- based permission. NFS. If a server limits access. NFS- mount the filesystem and make it available to. Preventing multihop mounts makes the. NFS server owning a filesystem. With this basic explanation of NFS usage. NFS mounts are combined with symbolic links.
