On the Asterisk host we run iaxmodem to listen to the analogue ports. Hylafax+ talks to the iaxmodem instances. This can be a network connection so it is not necessary to have Hylafax running on the host with the FXO connection. We have been running this setup with Avantfax as the UI since summer 2013 without problems. The load on the fax host is trivial. -- *** e-Mail is NOT a SECURE channel *** Do NOT transmit sensitive data via e-Mail James B.

There is no point in deluding yourself or your clients on that point. The first thing that you must do after a breach is detected, or even suspected, is to notify all affected parties. There is an institutional bias against revelation of security incidents because of the fear of embarrassment. This is often couched in terms using the word 'premature'. Failure to disclose at the earliest opportunity is unethical and ultimately self-defeating. You will never regain trust thereafter. The second thing to do, concurrently with the first, is to isolate the affected systems from the rest of your network. If that means physically pulling wires and putting the things on their own switch and LAN segment blocked from the rest of your networks then do it. If it means shutting down the affected hosts then do it. If if means disconnecting from the network at your gateway then do it. They are in and they are looking for ways to expand their foothold. Delaying containment is pointless. The third thing to do is to involve the authorities. Unauthorised computer access is an indictable offence in Canada and the UK. It is a federal felony in the U.S.A. If you have an incident then report it. That means you should have computer emergency response contact information and reporting protocols already in place. Now, with your clients and the authorities notified and the suspect systems isolated, you begin to map out your recovery strategy. The basic bones of which you have already written down and implemented in your backup and disaster recovery plan. A security breach is a disaster. You need to start with that point clearly in mind and proceed on that basis. Once corporate and client services are restored on clean hosts and reconnected to the Internet then begin your investigation. Use your AIDE and syslog records to determine the point of entry, the length of compromise and the extent of penetration. If possible identify the nature of the attackers and their target. Where possible keep the compromised hosts' disk drives unaltered for further technical analysis. Where warranted bring in forensic investigators to examine them. It will likely prove impossible to positively identify them but you should be able to glean some inkling if this was a targeted breach or an opportunistic one. If the former then they will be back and you will need to consider how to deal with the next assault. -- *** e-Mail is NOT a SECURE channel *** Do NOT transmit sensitive data via e-Mail James B.

Hylafax without modems - SIP?
by Gary Stainburn 26 Jan '16

26 Jan '16

I've just had to replace my Hylafax server as the cooling fan in the rack case has died and could not be replaced. My box runs three fax modems, one for each of the original 3 fax machines that got skipped years ago. This means that I now have 3 lots of: USB to seral converter (new box doesn't have any COM ports. 9pin->25-pin serial cable Modem power supply phone line analogue port on our Mitel 3300 controller I was wondering if there a better way? I've done lots of Googling and there is a lot of conflicting - and mostly very old - information out there. Does anyone have any more up-to-date opinions or advice on doing this? Most of the concerns about reliability were based on IP latency, but my fax server and my Mitel controller are both on the same Procurv Gigabit switch so hopefully that would be quick enough

What to do when you've been hacked?
by Benjamin Smith 26 Jan '16

26 Jan '16

No, we haven't been hacked. ;) We have a prospective client who is asking us what our policy is in the event of unauthorized access. Obviously you fix the system(s) that have been compromised, but what steps do you take to mitigate the effects of a breach? What is industry best practice? So far, searches haven't produced anything that looks consistent, except maybe identity monitoring for financial data. (EG: Target breach) We host a significant amount of educational data, but no financial information. How would we even respond to this question? I've also posted this question at https://www.reddit.com/r/linuxadmin/comments/42mi1r/what_to_do_when_youve_b… Thanks, Ben

At the moment we are withholding any judgement on the matter for want of clear empirical evidence respecting systemd's benefits and risks. On our test CentOS-7 systems we eventually switched to Mate. That in itself sorted out most of the most visceral negativity to RHEL7. But systemd, rightly or wrongly, remains a controversial issue here. And, being more interested in stability than features we will await further developments on that front. Maybe someone could convince Linus to embed an init processor into the kernel in a manner similar to how KVM made its way. -- *** e-Mail is NOT a SECURE channel *** Do NOT transmit sensitive data via e-Mail James B.

Intel Xorg driver for Intel HD graphics
by Jerry Geis 24 Jan '16

24 Jan '16

I found this page: https://01.org/linuxgraphics/downloads/2015q4-intel-graphics-stack-release I have an Intel NUC5C with "Intel HD" graphics and I'm trying to use CentOS 7.2 I downloaded the files suggested: cairo-1.14.4.tar.xz libva-1.6.2.tar.bz2 mesa-11.0.4.tar.xz intel-gpu-tools-1.13.tar.bz2 libva-intel-driver-1.6.2.tar.bz2 xf86-video-intel-2.99.917.tar.gz libdrm-2.4.65.tar.gz xorg-server-1.18.0.tar.bz2 and compiled, then installed them. All are working except the final one xorg-server-1.18 On the configure I get these errors: configure: error: Package requirements (fixesproto >= 5.0 damageproto >= 1.1 xcmiscproto >= 1.2.0 xtrans >= 1.3.5 bigreqsproto >= 1.1.0 xproto >= 7.0.28 randrproto >= 1.5.0 renderproto >= 0.11 xextproto >= 7.2.99.901 inputproto >= 2.3 kbproto >= 1.0.3 fontsproto >= 2.1.3 pixman-1 >= 0.27.2 videoproto compositeproto >= 0.4 recordproto >= 1.13.99.1 scrnsaverproto >= 1.1 resourceproto >= 1.2.0 xf86driproto >= 2.1.0 glproto >= 1.4.17 dri >= 7.8.0 presentproto >= 1.0 xineramaproto xkbfile pixman-1 >= 0.27.2 xfont >= 1.4.2 xau libsystemd-daemon xshmfence >= 1.1) were not met: Requested 'xproto >= 7.0.28' but version of Xproto is 7.0.26 Requested 'randrproto >= 1.5.0' but version of RandrProto is 1.4.0 I'm not sure what to do with these errors. The "proto" packags are nothing that I can install -devel packages for as these packages are not even present on the Packages directory that I see. Any thoughts how I might get the Xorg server running on the "Intel HD" graphics of the NUC5C? Thanks, Jerry
