Re: [Vserver] pam rlimits
Hello, Quick and dirty solution : you can edit the files that refer to pam_limits.so in your /etc/pam.d/ Generally, system-auth is concerned. You simply have to comment the line that refers to pam_limits #session required pam_limits.so The cause of the problem is that pam_limits try to set limits that are already sets _outside_ of the guest. If you want to play with the limits sets, you can modifiy /etc/security/limits.conf of the guest...

Re: [Vserver] NFS mount home directories
Hello, We are using a lot NFS here on XTERM vservers and we have tried and tested both solutions: 1) mount NFS somewhere on the /host then use mount --bind 2) mount NFS before directly on the /vserver directory Both are working fine. You can have locking with nfslock and, as Herbert mention previously, this is as reliable as ... NFS ;-) What is important is to "tweak" (well, if necessary) your startup sequence so that all is fine on the host before starting any vserver that depend on the NFS files. Also, you should use "v_portmap" instead of portmap if you plan to do NFS inside a vserver (well, in our case, we are using unfsd3 as this is only read-only partitions for the XTERM). In that respect, we think that mounting directly NFS inside the vserver is a bit more reliable than "mount --bind". When you are using mount --bind, the directory will be binded, even if the NFS directory is not mounted which can lead to serious problem, especially if you are using pam_mkhomedir... If you want to restore the "correct" behavior, you have to unmount the directory then remount it once your NFS is present. We don't have this kind of problems when mouting the NFS share directly inside the vserver. We are using TCP NFS for better reliability and performance (when the server has some kind of load...)

Re: [Vserver] V_xxxx not running ?
Hello, Well, it certainly _was_ true at some point, especially when I was testing the vserver on my laptop ; I don't think this is the case now. We simply experiment that some programs have to be run on the host and don't allow to change port/restrict IP/etc. The v_* tools are, IMHO, a generic way to circumvent this kind of problem. This is especially true for portmap (i.e. : you need NFS on your host and you provide NFS we unfsd3 on a vserver, etc.) and there is no possibility to specify this in a config file (as far I know!). The same can be true for other programs : openSLP ?, Also, this can really help the newcommers to the vserver technology. I agree with you that, most of the time, you need those tools when you are using vservers on a "regular" host. However, it is really easy to use these tools and, in the process, understand how the vservers and the host share certain ressources. "Chasing" each and every config file of services started on your host (apache:443, SSH, mySQL, postgreSQL, etc.) can be a "not very productive task" especially during a test...

Re: [Vserver] V_xxxx not running ?
Hello, Well, I think that this is a useful tool for the vserver project. We are using v_portmap as well as some others v_* scripts. After having installed several vserver hosts I think it is much more easy to modify the services than to go after every application and modify one or several configuration file. Also, it is easy to check the existing services running on a given host and to create the v_* scripts in order to make sure that no port conflict will occur between the vservers and the host.
