Inquiry:External USB modem and Remote PC Access?
by hadi motamedi 27 Oct '09

27 Oct '09

Dear All Please be informed that I checked for the presence of internal modem on my CentOS server , as the followings : #dmesg |grep -i modem #lspci |grep -i modem #lshw |grep -i modem According to the output , it seems that my CentOS client does not contain internal modem . So I decided to add external USB modem and make use of an PCAnyWhere like application that enables for Remote PC Access . Can you please do me favor and let me know how can I add the external USB modem to my CentOS host and please propose for an PCAnyWhere like application that can be installed on my CentOS client and enables for remote dialup connection (as the PCAnyWhere does for the MS Windows clients) ? Let me thank you in advance Regards H.Motamedi

Madwifi drivers afeter 2.6.18-128.
by Alessandro Ren 27 Oct '09

27 Oct '09

I have a atheros wiifi card on my Centos 5 that I use as a access point using hostapd. I noticed that after the upgrade to kernel 2.6.18-128 or above, the atheros driver comes with the kernel, ath5k, and it does´t let hostpad ou iwconfig set master mode on the card. Up to kernel 2.6.18-92 is workedd just fine using madwifi from rpmforge. Any ideas on that? Tks. __________________________________________________

Running SSH on a different port
by ML 27 Oct '09

27 Oct '09

HI All, With my new firewall in place, it has opened my eyes to how much traffic gets blocked in a single day and also what are the most active rules. I get *a lot* of requests for port 22. How does one switch ssh ports? What is a good port to use? What ramifications does it have when I need to ssh in? Is it as simple as ssh user@hots:port? Best, -ML

Need some help with logwatch.
by James B. Byrne 27 Oct '09

27 Oct '09

I am trying to get a logwatch summary emailed to a central address from a cron job. The tasd was copied verbatim from a system which does this already. Both are shown below. host1 crontab -l as root 45 7 * * * /usr/sbin/logwatch --service http --service imapd --service pop3 --service sshd --service vsftpd --service zz-disk_space --service zz-network --service zz-sys --mailto support(a)harte-lyne.ca host2 crontab -l as root 45 7 * * * /usr/sbin/logwatch --service http --service imapd --service pop3 --service sshd --service vsftpd --service zz-disk_space -- service zz-network --service zz-sys --mailto support(a)harte-lyne.ca #Logwatch summary My problem is that only the first gets delivered to support(a)harte-lyne.ca. The second gets delivered to root(a)host2.harte-lyne.ca and not to support. It has been a considerable time since I dealt with logwatch on the first machine and I cannot remember is there was any special configuration of logwatch itself to enable this to happen. Does anyone know what I might be overlooking? The curious thing is that if I cut and paste the host2 cron job entry into a terminal window that is logged in as root on host2 then the logwatch report goes to support as I intend. -- *** E-Mail is NOT a SECURE channel *** James B.

5.4 DVD
by m.roth＠5-cent.us 27 Oct '09

27 Oct '09

I admit I wasn't following the screaming and yelling about 5.4, so excuse me if this has been answered.... My boss tells me he wants me to start rolling out 5.4. I want to d/l & burn a DVD... but when I looked at a number of mirrors, the .iso is from 1 Oct, while the CD .iso's are from the 14th... yet 5.4 was officially announced the other day. Am I missing something, or do the mirrors have a pre-release DVD .iso, with no fixes in the last three weeks, or ...? mark

CentOS 5.4 .x86_64 and perl.i386
by Gregory P. Ennis 26 Oct '09

26 Oct '09

To All, Thanks to the CentOS guys for 5.4; sure appreciate your work. I have one question. I had to remove perl-5.8.8-18.el5_3.1.i386 on two x86_64 machines in order to get perl.x86_64 4:5.8.8-27.el5 to update. Does this represent a change from 5.3 to 5.4 and should I be concerned about the loss of perl-5.8.8-18.el5_3.1.i386. So far I have not found anything broken. Greg Ennis
