Email access via Android device
by Frank Cox 08 Oct '13

08 Oct '13

I'm pretty sure that this is possible, but I don't currently know enough about email to know where to start. My main desktop computer runs Centos 6 and my preferred email client is Sylpheed, which supports both POP and IMAP email, and my "internal network" has a static IP address, so getting access to the computer from the big scary world via my phone isn't a problem. I have six different email accounts that live on various servers. I have Sylpheed set up to poll each account once every ten minutes using POP3 and download all incoming mail. Upon receipt, I have a whole lot of filters in Sylpheed to sort the mail into various subdirectories of my Mail directory. For example, one of my directory structures under Mail is inbox/1/2, and email may be sorted in Mail/inbox or Mail/inbox/1 or Mail/inbox/1/2, or other subdirectories outside of inbox like, for example, Mail/3. In short, I have a dozen or so subdirectories that Sylpheed sorts mail into based on various criteria like From or Subject. What I would like to do is somehow make this whole thing available on my Android phone (Samsung Galaxy 3). As it sits right now, if I am not sitting in front of my computer the only way I can check my email is to ssh into it and look at the files in each of those subdirectories using a text utility like less; this is really inconvenient and I can't reply to emails that way until I get back in front of my computer. I'm thinking that I need to run some kind of a mailserver on my computer that can be accessed by both Sylpheed locally and by ??? on my Android device. I get the impression that if I wanted to hand all of my email over to gmail I could then have something like this working. I don't particularly want to do that; I would rather have something running on my own machine to do it. I could use something else to poll for my email (fetchmail?). Sylpheed does have a configuration setting that I'm not currently using that says "Enable strict checking of summary caches -- enable this if the contents of the folders may be changed by other applications" so based on that I think it can handle having messages magically changed by a program on my Android device. What is the best way to approach this? My best idea so far is to set up fetchmail (or something) to do the pop downloads of incoming mail, and have some kind of a local imap server running though which I access the actual mail via any email client that can work with an imap account. Then I can set up Sylpheed to access only one account, that being the one on my local computer, and run some imap-using mail client on the Android device for remote access. Having never actually used an imap email account in this way, that leads to a couple of other questions. (The only thing I've ever done with imap is set up squirrelmail.) What about filtering the email into those directories? Procmail? And what happens to sent email -- I assume that the SMTP part of the mail client wouldn't actually change -- I would still send outbound mail directly through the mailserver where my email account exists, right? But does it (can it) also send a copy to the imap mail store so I can send email from Android and later on review what I sent with Sylpheed? -- MELVILLE THEATRE ~ Real D 3D Digital Cinema ~ www.melvilletheatre.com

CENTOS 5 incoming SFTP
by John McKelvey 07 Oct '13

07 Oct '13

Hello, I have a CENTOS 5 box that can reach the internet and can ping to/from all windows system on my home network. The catch is that I can not connect to the box using SSH from any windows machine, though they can easily ping the linux box and vice-versa. Suggestion of a possible solution would be most appreciated. Many thanks! John -- John McKelvey 10819 Middleford Pl Ft Wayne, IN 46818 260-489-2160 jmmckel(a)gmail.com

Unresolved references in libnetsnmpagent.so
by Styma, Robert E (Robert) 07 Oct '13

Hi, I am running an up to date centos5.9 system. The package, net-snmp-devel-5.3.2.2-20.el5 Contains among oteher things: /usr/lib/libnetsnmpagent.so When I link with this library (-lnetsnmpagent), I get a bunch of unresolved references.: My Google searches has not given me hints to where the C to Perl library exists. I would guess that yum would have loaded the correct package as a dependency: Could someone point me to the correct library? Thank you. /usr/lib/gcc/i386-redhat-linux/4.1.2/../../../libnetsnmpagent.so: undefined reference to `perl_free' /usr/lib/gcc/i386-redhat-linux/4.1.2/../../../libnetsnmpagent.so: undefined reference to `perl_parse' /usr/lib/gcc/i386-redhat-linux/4.1.2/../../../libnetsnmpagent.so: undefined reference to `Perl_eval_pv' /usr/lib/gcc/i386-redhat-linux/4.1.2/../../../libnetsnmpagent.so: undefined reference to `perl_run' /usr/lib/gcc/i386-redhat-linux/4.1.2/../../../libnetsnmpagent.so: undefined reference to `perl_alloc' /usr/lib/gcc/i386-redhat-linux/4.1.2/../../../libnetsnmpagent.so: undefined reference to `make_tempfile' /usr/lib/gcc/i386-redhat-linux/4.1.2/../../../libnetsnmpagent.so: undefined reference to `boot_DynaLoader' /usr/lib/gcc/i386-redhat-linux/4.1.2/../../../libnetsnmpagent.so: undefined reference to `perl_construct' /usr/lib/gcc/i386-redhat-linux/4.1.2/../../../libnetsnmpagent.so: undefined reference to `perl_destruct' /usr/lib/gcc/i386-redhat-linux/4.1.2/../../../libnetsnmpagent.so: undefined reference to `hosts_ctl' /usr/lib/gcc/i386-redhat-linux/4.1.2/../../../libnetsnmpagent.so: undefined reference to `Perl_newXS' Bob Styma Phoenix, AZ

CentOS Continuous Release Updates are Available for 5.10
by Johnny Hughes 07 Oct '13

07 Oct '13

The Continuous Release Updates for CentOS-5.10 are released to the CR repo. The anaconda and centos-release packages for 5.10 are not released into the CR (as they may need to change for the installable tree), but all other updates are there. For information on what the CR is, see this link: http://wiki.centos.org/AdditionalResources/Repositories/CR We are now focusing on creating an installable tree and creating the ISOs for CentOS-5.10 .. I would expect that we would have the full 5.10 release (tree and ISOs) in 10-14 days from this announcement. For a list of the updates in the CR, see this link: http://lists.centos.org/pipermail/centos-cr-announce/2013-October/thread.ht… Thanks to the CentOS QA team for their effort in testing this CR Repository so we can get it released so soon after the upstream release of EL 5.10. Thanks, Johnny Hughes

Anyone else getting Sane throwing i/o error after upgrades?
by Rob Kampen 07 Oct '13

07 Oct '13

Hi List, I have an old HP psc2210 that has performed well with xsane, libsane and related drivers until today. Note in the yum logs that recent upgrades to Sep 23 21:28:49 Updated: hplip-common-3.12.4-4.el6_4.1.x86_64 Sep 23 21:28:50 Updated: hplip-libs-3.12.4-4.el6_4.1.x86_64 Sep 23 21:29:17 Updated: libsane-hpaio-3.12.4-4.el6_4.1.x86_64 appear to have caused this error. scanimage -L reports device `hpaio:/usb/PSC_2200_Series?serial=MY34SF74HN0G' is a Hewlett-Packard PSC_2200_Series all-in-one but xsane reports (xsane:10677): Gtk-WARNING **: GtkSpinButton: setting an adjustment with non-zero page size is deprecated upon startup, however the gui comes up fine, an attempt at scanning gives scanimage: sane_start: Error during device I/O device locks up and needs reset. Anyone else having this issue? I guess only option is to downgrade?? TIA Rob

Re: [CentOS] php 5.1 to 5.3

I am using webtatic on CentOS 5.x. I started using it some years back because as I can remember (vaguely) I had problems using php53 RPMs (can't remember details, however). Thanks for php 5.4 info - I haven't used it yet. I installed remi (php 5.5) on CentOS 6.x but, yes, it seems many apps don't like php 5.5.

Is Java insecure ?

Hi Everyone I am considering learning Java. There have been well publicized Java security incidents recently that make me not want to learn it. However it's in Centos and I trust Centos, are the concerns in the media blown out of proportion ? -Patrick

You can connect to a samba share without user or password authentication. That's how I have my server setup at my house.
