Debian AMD64 or i386
by zlinw＠mcmedia.com.au 19 Sep '15

19 Sep '15

I currently I have 3 systems, two of these have Debian 1386 installed (7.x) the third has AMD64. I have not gone AMD64 with any enthusiasim because of some problems. The first problem is the AMD64 machine locks up regularly generally when playing videos, Note, xine will not work on this machine so I use vlc. The lock up usually involves the whole machine EXCEPT for the audio, one can only get out of it with a power off, a hard rest will NOT generally work, ie it sometimes does and sometimes does not. The second point is not really a decent problem, its that googleearth is not __easy__ to install as its a 32 bit program. The package system just winghes that it needs some i386 libraries, but will not do anything about it. IMPORTANT NOTE, THIS MEANS YOU, I do not regard this as a show stopper as all it needs is to install the apropriate items manually and I am quite capable of doing that. Its just that along with the lockups and xine not working, its another reason not to bother with AMD64. The machine itself is new (at the time, its nearly 18 months old now, ie the problem is that old) using a Gigabyte Sabertooth X79 motherboard and an AMD 7870 GPU running the Radeon OS driver. Debian has been updated a number of times without any improvement. Note WindowsXP runs completely OK on the machine so the hardware is OK. I am on the verge of dumping AMD64 all together, anyone have any ideas? Maybe Debian AMD64 does not like the Sabertooth X79, I have had a similiar situation on the system this post is being writen on. lindsay linux now since 1993, kernel 0.96d.

AvantFAX on debian Jessie?
by Neale Banks 13 Sep '15

13 Sep '15

Hi all, Has anyone installed AvantFAX on debian Jessie? A quick look over the install script suggests it'll probably be OK with a couple of mods (hopefully just the required package names), but I'd be grateful for any anecdotes from the coalface. Thanks, Neale.

bind chroot, bind mounts and selinux
by Tom Robinson 11 Sep '15

11 Sep '15

Hi All, I'm migrating a CentOS 6 bind instance (chrooted) to a CentOS 7 box and am curious of people's opinions on chrooting vs selinux as a way of securing bind. The bind-chroot on CentOS 7 also comes with a script (/usr/libexec/setup-named-chroot.sh) that sets up the much maligned systemd and, through bind mounts, creates and extra level of chroot hierarchy giving: /var/named/chroot/var/named/chroot/var/named which seems totally unnecessary. I'm sure that bind-chroot would be happy enough running without the bind mounts but would I be loosing anything in terms of security? Also, would I bother with chrooting at all if selinux can secure the environment for me? My own opinions aside what do others think and has anyone had experience with this?

NFSv4 on CentOS without Kerberos - getting rid of nobody
by Peter Ross 08 Sep '15

08 Sep '15

Hi all, I just spin off two CentOS6 VMs to replicate a problem I had on Friday afternoon at work. I want use NFSv4 to share folders. Short, from memory, I have on the server: - /etc/exports populated - domainname configured - domain in /etc/idmapd.conf - rcpidmapd running On the client, I have - /etc/fstab entries with nfsvers=4 - SecureNFS=no in /etc/sysconfig/nfs - domainname configured - domain in /etc/idmapd.conf - rcpidmapd running When I mount, it works, but all files belong to nobody.. What do I miss? If I start rpcimapd in verbose, it complains about /proc/net/nfsv4/nfstoid or something similar missing(sorry, I am not there yet with my replicas) but I am not sure whether this matters. DuckDuckGo and Google did not help much yesterday. I do not have Kerberos or LDAP configured, the firewall (2049 connection only) restricts me and I 'don't mind' that the two machines trust each other. The environment is quite isolated and under tight control. Thanks for ideas Peter

Kind of service/VM/host/IP/location/asset register (and more)
by Peter Ross 04 Sep '15

04 Sep '15

Hi all, I am looking for an easy way to keep things in sync with reality.. Means: IP addresses, DNS, out of bounds IPs, blade centre, ESXi hosts etc. - and if possible physical location, asset register, monitor configuration, password safe etc. The current mix of DNS on Active Directory, Excel spreadsheets etc. "doesn't cut it". It's incomplete, it's redundant, it's not consistent.. and we spend sometimes too much time to find critical information just to get a few little things done, and things are overlooked etc. I had actually things in some "password-style" (with ":" as the separator) files before, and that was in version control and worked quite well, but from a certain point onwards it becomes a bit complex (I have much more variation in setup here, e.g) and you cannot convince other people that old-fashioned files are not that bad;-) So all ideas are welcome. Regards Peter

Microsoft Exchange Alternative??
by craig.luv＠shakenautomotive.com.au 02 Sep '15

02 Sep '15

Hi, I'm getting the Microsoft Exchange pressure here at work again. We have survived with postfix/dovecot and sieve for quite a number of years. However I have to admit the needs for calendar sharing, meeting requests etc is getting pretty strong. Any suggestions? Or advice about the following? (must work with MS Outlook) ref: https://www.linux.com/learn/tutorials/338482-microsoft-exchange-alternative… These two seem like the best fit so far.. * Zimbra * Open-Xchange Regards, Craig

beginners SIG event idea
by Russell Coker 30 Aug '15

30 Aug '15

I'm thinking of running a beginners SIG event for setting up a mail server. I would give everyone a virtual machine and a NS record of their choice under the unixapropos.com domain. Then you can setup a DNS server and a mail server. This wouldn't be running on the big server and will only have space for maybe 14 virtual machines with 400M of RAM each. The limited number of VMs would mean that people would have to work in groups if it's as popular as the last training event. Who's interested? Also who's available to help in training? I'm good at Postfix and Dovecot but it would be good to have people with experienece with other software. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Faking a file on a filesystem
by Sean Crosby 27 Aug '15

27 Aug '15

I have a need for a way for a regular user (i.e. non root) to "override" a file on a filesystem with one of their own, but just for the lifetime of a script. I'll give you an example. One of my users runs a program which is distributed in a package (i.e. not changeable by them). That program is looking for a file, /path1/file1. My user would like to change this file to a different version of the file in different scripts. I'm not aware of one, but is there a way to redirect file open calls for /path1/file1 to /path2/file2 in a script? It only has to be for file open/read calls, and not write. The /path1 filesystem is not writeable by the user. Is there maybe a FUSE filesystem which will allow this, or something else? Cheers, Sean

Cannot Free USB Disk Space
by David Zuccaro 26 Aug '15

26 Aug '15

I'd like to report a strange problem. I was backing up my desktop last night to an external usb disk last night. The backup failed to complete because I completely filled up the disk. df -h /dev/sdf1 1.4T 1.4T 0 100% /media/dz/5540d70d-... So this morning I deleted (using sudo rm -rf) an old directory on the usb disk which had about 30 GB of data in it. Now the problem is that df still reports the disk is completely full -- even after rebooting. /dev/sdf1 1.4T 1.4T 0 100% /media/dz/5540d70d-... Can someone please explain to what is going on here? Thanks David Zuccaro BSc (Chemistry, University Of Melbourne), GradDipCompSci (Monash), GradDipEd (Melbourne)
