Dear all, I'm currently working on converting mathematica code (https://github.com/ASDSE/thermosimfit/blob/master/Packages/thermoHD-Comp/thermoCacheHD-1Comp.m) to R. The code is related to solve algebraic systems. > eqthermo = {h0 == h + hd + hga, d0 == d + hd, ga0 == ga + hga, kga == > ???? hga / (h * ga), kd == hd / (h * d)}; > > (* IDA HD*) > sthdIDAcacheHD[fkd_, fkga_,

Folks, I know this must be a configuration problem. Just changed servers last nite -- an interim server running 1.6.1.6. Copied all of /etc/asterisk to the new server and fired it up. Now I'm getting: [Oct 14 12:28:10] ERROR[8471]: cdr_pgsql.c:309 pgsql_log: Failed to insert call detail record into database! [Oct 14 12:28:10] ERROR[8471]: cdr_pgsql.c:310 pgsql_log: Reason: ERROR: syntax

Hi, I have to install CentOS on a spare partition of a laptop with Windows pre installed. Is there anything I have to watch out for? Couldn't find anything in the wiki or does the installer handle this well without me doing some magic, or so? TIA, Frank.

Hi, how can a specific device driver in CentOS 7 be blacklisted, so that it doesn't load at boot time? We have Infiniband adapters which are not completely supported by CentOS and we want to silence the error messages for the time being. I tried with the files /etc/modprobe.d/blacklist /etc/modprobe.d/blacklist.conf and with entries mlx5_core mlx5_ib blacklist

Also you should probably use dovecot director to ensure same user sessions end up on same server, as it's not supported to access same user on different backends in this scenario.

Hi, since I updated my workstation from CentOS 7.4 to 7.5, Firefox and Thunderbird (both 52.8.0, from CentOS repos) regularly freeze (or crash) and cannot be restarted afterwards. Trying to start them results in a "Bus error (core dumped)" (Firefox) and "Killed" (Thunderbird). The system log then shows: kernel: NFS: nfs4_reclaim_open_state: Lock reclaim failed!

If you just want active/standby, you can simply use corosync/pacemaker as other already suggest and don?t use Director. I have a dovecot HA server that uses floating IP and pacemaker to managed it, and it works quite well. The only real hard part is having a HA storage. You can simply use a NFS storage shared by both servers (as long as only one has the floating IP, you won?t have issue with the

Hi, this puzzles me: On one of our developer workstations, all ports with the exception of SSH are closed: $ firewall-cmd --list-all public (active) target: default icmp-block-inversion: no interfaces: eno1 sources: services: ssh dhcpv6-client ports: 22/tcp protocols: masquerade: no forward-ports: source-ports: icmp-blocks: rich rules: $ but still port

Hi, Wine came with Internet Explorer. I also installed FLV Player and the Orion Platinum demo to test. Only FLV Player will run. Internet Explorer opens (and installs the Gecko engine), but then freezes - i.e. big white nothing. When I try to run the Orion demo, all I get is errors: Code: koen at pavor:~/.wine/drive_c/Program Files/OrionPlatinum$ wine OrionPlatinum.exe

Hi! I have a setup with Asterisk in front of a PBX connected with ISDN to the PSTN and to the PBX. This Asterisk (a old 1.2 instance) is doing ENUM for outgoing calls and allows incoming calls per SIP. Recently the IP connectivity for this location was down the whole telephony was down too - not even incoming calls did work. This is really strange as incoming calls from PSTN are routed

hi, i was able to successfully run vfs_shadow on a samba share with win xp shadow copy client. but i think it?s currently not implemented that one could export [homes] with this vfs object, because AFAIK each @GMT-snap has to resist directly under the samba share. but [homes] is a virtual share representing different shares (depending on users). has anybody hints about using vfs_shadow with

Hello, does it in any respect (throughput/performance, cpu load, I/O load, resilience, ...) matter, if one mounts subdirectories of an NFS (v3) export into separate directories or if one just mounts the parent directory? I.e. like this: server:/export/base/a -> /mnt/a server:/export/base/b -> /mnt/b server:/export/base/c -> /mnt/c server:/export/base/d -> /mnt/d

Hello, I''ve configured two xen hosts (dom0) sharing a LUN on a SAN. My firs obiective is to run different domU on the two hosts, and implement live migration between them. Subsequently, I''d like to implement HA, so if a xen host goes down, domUs will be restarted on the other one. What''s the better way to obtain this? I think I need a cluster file system to
