Postfix mail server procedure
by Jonathan Vomacka 14 Nov '11

14 Nov '11

CentOS Community, I was wondering if anyone had a good resource or procedure for a step by step in installing a mail server with Centos. There ARE documents on google, however almost all that i've found were outdated from 2005. Does anyone know where I can find this type of document for a mailserver Postfix + MySQL + SpamAssassin + ClamAV + Squirrelmail + Postfixadmin, etc?

No more sound since gfx card update
by lhecking＠users.sourceforge.net 14 Nov '11

14 Nov '11

Our workstation vendor EOL'd the gfx card we were buying and replaced it with a different model. With the new card, sound is no longer working. Previous system: # lspci |grep -i audio 00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller # aplay /usr/share/sounds/alsa/Noise.wav Playing WAVE '/usr/share/sounds/alsa/Noise.wav' : Signed 16 bit Little Endian, Rate 48000 Hz, Mono # New system: # lspci |grep -i aud 00:1b.0 Audio device: Intel Corporation 82801JI (ICH10 Family) HD Audio Controller 02:00.1 Audio device: nVidia Corporation GF108 High Definition Audio Controller (rev a1) # aplay /usr/share/sounds/alsa/Noise.wav ALSA lib confmisc.c:768:(parse_card) cannot find card '0' ALSA lib conf.c:3513:(_snd_config_evaluate) function snd_func_card_driver returned error: No such file or directory ALSA lib confmisc.c:392:(snd_func_concat) error evaluating strings ALSA lib conf.c:3513:(_snd_config_evaluate) function snd_func_concat returned error: No such file or directory ALSA lib confmisc.c:1251:(snd_func_refer) error evaluating name ALSA lib conf.c:3513:(_snd_config_evaluate) function snd_func_refer returned error: No such file or directory ALSA lib conf.c:3985:(snd_config_expand) Evaluate error: No such file or directory ALSA lib pcm.c:2184:(snd_pcm_open_noupdate) Unknown PCM default aplay: main:583: audio open error: No such file or directory # Is it possible to disable the NVidia sound device and revert to system board sound? The card is a Quadro 600 with DVI and DisplayPort adapters, and the systems are running CentOS5.4. Alternatively, is there a driver?

binding additional IP addresses to centos6 on one interface
by Jonathan Vomacka 14 Nov '11

14 Nov '11

I know this was discussed before, and I have seen a million ways of doing this via online docs. I have a quick question that hopefully the community can help me out with I am trying to add a block of 10 IP addresses. Rather then create 10 different alias files, I want to use the RANGE file. Docs say to use the following format: IPADDR_START=x.x.x.x IPADDR_END=x.x.x.x CLONENUM_START=0 If the IP's that are given to you are on a completely seperate gateway / netmask, how would you enter it into this file? Is it necessary? Please advise.

Thanks, Rajagopal Can't see any graphics driver for RHEL-anything on the HP support site.

Trouble with Mailman
by John J. Boyer 13 Nov '11

13 Nov '11

I have set up Mailman on a virtual private server from 1and1 running Centos, though I can't tell which version. The system has 2 GB of memory. Mailman is receiving posts, but it is not sending them out to everybody. It is also getting some out-of-memory errors. The server is also runing Plesk for Web hosting. Something on the server is leaking memory. When first booted it has nearly 1.5 GB of free memory. Now this is down to .75 GB. Any hints will be appreciated. Thanks, -- John J.

how to get dev/dsp and oss modules back
by Shaun Jones 13 Nov '11

13 Nov '11

Hello I have some older programs that require OSS and /dev/dsp I have tried the pulseaudio trick with padsp but some work and some don't. I have also edited the /etc/modprobe/dist-oss-conf and uncommented the line that says install snd-pcm /sbin/modprobe --ignore-install snd-pcm && /sbin/modprobe snd-pcm-oss && /sbin/modprobe snd-seq-device && /sbin/modprobe snd-seq-oss This was supposed to work at least from what I have read to get the modules back but unfortunately it has not. I have no /dev/dsp at all or any oss modules when doing a lsmod. As you can see here snd_emu10k1_synth 4968 0 snd_emux_synth 30789 1 snd_emu10k1_synth snd_seq_virmidi 4176 1 snd_emux_synth snd_seq_midi_event 5815 1 snd_seq_virmidi snd_seq_midi_emul 5187 1 snd_emux_synth snd_seq 46091 4 snd_emux_synth,snd_seq_virmidi,snd_seq_midi_event,snd_seq_midi_emul snd_emu10k1 128854 5 snd_emu10k1_synth snd_rawmidi 18705 2 snd_seq_virmidi,snd_emu10k1 snd_ac97_codec 95710 1 snd_emu10k1 ac97_bus 942 1 snd_ac97_codec snd_pcm 66969 3 snd_emu10k1,snd_ac97_codec snd_seq_device 5354 5 snd_emu10k1_synth,snd_emux_synth,snd_seq,snd_emu10k1,snd_rawmidi snd_timer 18308 3 snd_seq,snd_emu10k1,snd_pcm snd_page_alloc 7080 2 snd_emu10k1,snd_pcm snd_util_mem 2950 2 snd_emux_synth,snd_emu10k1 snd_hwdep 5320 2 snd_emux_synth,snd_emu10k1 snd 52754 17 snd_emux_synth,snd_seq_virmidi,snd_seq,snd_emu10k1,snd_rawmidi,snd_ac97_codec,snd_pcm,snd_seq_device,snd_timer,snd_hwdep soundcore 6460 1 snd I have tried it with both pulseaudio installed and pulseaudio not installed and no go either way. So my question is this, have the OSS modules and support been removed from the kernel like many other distros have done? If so I will have to rebuild the kernel to get this functionality back which really is no big deal, but was hoping someone would know something I do not, thanks in advance. -- Mister Jones

Re: [CentOS] Redhat vs centos vs ubuntu
by Errol Mangwiro 12 Nov '11

Hi, Sorry about the top-posting, I'm replying from my blackberry. I've been following this thread for a while and really don't see why people respond so rabidly to criticism. If something bothers/bores me about a thread I just Ignore the thread/user. If no one is interested the thread dies out on its own. However, let if someone has something to say let them. The people who reply/comment *want* to talk about it. No one forces anyone to *read* the thread. Just ignore it. It's that simple. Going as far as threatening to ban a user for commenting negatively or positively or. even "off-topic" (this is relative, e.g., I found the discussion on the strengths & weaknesses of ubuntu/centos/redhat el interesting & in some cases informative as the various issues were debated). I would think that there's nothing wrong with allowing people the freedom to discuss centos-related stuff on the centos list. As I mentioned earlier it's as simple as ignoring a thread if don't like it. There's no need to flame, ban or go on a rant just because someone says something you don't like about your favourite OS has been attacked. For the record I *like* centos & am in the process of replacing some of my fedora & ubuntu server installations *with* centos.

Otherwise everyone needs a plan B. What is older than that now if you look at 6.x CR? The only thing lagging right now is the building of new install media. But if you install 6.0 and use CR, you are in good shape. There are even updates in there that are newer than 6.1 (it also contains the updates TO 6.1). I can never say how long it will take to build something that we have not built yet ... if we have to redesign a system from scratch, it will take time. You are correct, if CentOS does not work for you then move on. Move on to a new OS and move on to a new list. > >> So I ask you, and all the others, to _please_ consider that the _vast_ >> majority of active readers of this list don't care one way or another >> about opinions of CentOS vs Ubuntu or hearing, yet again, about your >> displeasure with whatever is irritating you today about CentOS. > > Sorry, but I don't believe that there is any such vast majority that > isn't concerned about the situation. This list is for the community to use to get and provide support for CentOS ... not for constant bellyaching and non stop whining. This list has become non usable because of the trash that it has become. Starting today, I will be banning people from posting on this list.

I want to confirm that the solution posed by René re installing kmod-fglrx from elRepo also works well for HP Proliant servers (in my case DL360 G6) with ATI gfx to restore the text boot progress display and virtual terminals. Kudos for ending a long and maddening search for a fix. ref: https://www.centos.org/modules/newbb/viewtopic.php?topic_id=32526 thx
