pam_access.so restrictions not working - syntax errors?
by Dirk H. Schulz 20 Mar '09

20 Mar '09

Hi folks, I want to restrict root access via ssh to certain (internal) hosts. That is what pam_access.so is for, I thought, so I configured: in /etc/security/access.conf I added (nothing in there before): + : root : 192.168.123.0/24 10.72.0.0/16 - : root : ALL in /etc/pam.d/ssh I added at the end: account required pam_access.so Then I restarted the ssh server. Basically, this kinda works. Cron suddenly had no right to do it's job, so I had to add + : root : LOCAL to /etc/security/access.conf But there still is no restriction on ssh logins by root - I can still login from anywhere. Next I tried putting it in one line in /etc/security/access.conf: - : root : ALL EXCEPT LOCAL 192.168.123.0/24 10.72.0.0/16 That did not change anything, still I can log in via ssh. I am stuck. According to documentation and the examples on the net this should be the right syntax. And, by the way, in my /etc/ssh/ sshd_config I have "UsePAM yes". Any help or hint is appreciated. Dirk

pam_ldap and nss_ldap failover
by Paul Heinlein 20 Mar '09

20 Mar '09

I'm (finally) getting around to putting a backup LDAP authentication server on my network. The backup uses syncrepl to grab the database, and to my eyes both LDAP servers answer read queries identically. I'm testing the client side of this configuration on virtual CentOS 5 i386 machine. /etc/ldap.conf reads ----- %< ----- base dc=DOMAIN,dc=com timelimit 30 bind_timelimit 30 idle_timelimit 300 nss_initgroups_ignoreusers root,ldap,named,[... trimmed ...] uri ldap://ldap1.DOMAIN.com ldap://ldap2.DOMAIN.com ssl start_tls tls_cacertdir /etc/openldap/cacerts pam_password md5 ----- %< ----- The client will bind to whichever server is listed first after the 'uri' directive. In the config snippet, it's 'ldap1' -- but it works the other way too. If the first-listed server goes away, the client never seems to try to find or bind to the second-listed server (where "never" == my patience limit of about an hour). Once the first-listed server goes away, all password authentication fails, though getent passwd and getent group still work (presumably because of nscd). Has anyone else experienced this or, more importantly, figured out a way to get failover to work in a reasonable timeframe? -- Paul Heinlein <> heinlein(a)madboa.com <> http://www.madboa.com/

stty and sockets
by Jerry Geis 20 Mar '09

20 Mar '09

With local com ports I can use stty to inspect the port settings. Is there a similiar method with a socket connection? I have an odd situation happening where my data collection program that is working on 3 machines is not working on the 4th. The program opens a socket to remote RS232 device no data is recieved. strangely though if I "telnet IP port" to the device it will send the data on this 4th unit. (odd that it works on 3 units but not the 1). I was thinking there must be something different with the way telnet is setting up the socket than I am setting up the socket. Is there a command or method that can inspect socket options like I can with stty for RS232 lines? If so how? Thanks, Jerry

minimal installation - kickstart error
by Tom Brown 20 Mar '09

20 Mar '09

Hi I have inherited some kickstarts that attempt to remove some packages that at some point its been deemed they are not required. I am migrating all this over to cobbler but trying to get to the bottom of this error that although the kickstart completes sshd cant start as the package nss is not installed. It fails with this Installing nss - 3.11.99.5-2.el5.centos.x86_64 error: %pre(nss-3.11.99.5-2.el5.centos.x86_64) scriptlet failed, exit status 255 error: install: %pre scriptlet failed (2), skipping nss-3.11.99.5-2.el5.centos Which seems to happen due to this error while loading shared libraries: libssl3.so yum tells me # yum provides libssl3.so nss.i386 : Network Security Services nss.i386 : Network Security Services so # yum search "Network Security Services" nss.i386 : Network Security Services nss-tools.x86_64 : Tools for the Network Security Services nss-devel.x86_64 : Development libraries for Network Security Services nss.x86_64 : Network Security Services nss-devel.i386 : Development libraries for Network Security Services nss-tools.x86_64 : Tools for the Network Security Services mod_nss.x86_64 : SSL/TLS module for the Apache HTTP server nss.i386 : Network Security Services But anyone know what package messing this up as from what i can see nothing there is being 'removed' in the kickstart - below is a full list of packages removed in the kickstart thanks for any tips tom # individual packages to remove -acpid -apmd -aspell -aspell-en -at -autofs -bc -beecrypt -binutils -bluez-bluefw -bluez-hcidump -bluez-libs -bluez-utils -cpio -crash -cryptsetup -cups -cups-libs -cyrus-sasl -cyrus-sasl-md5 -cyrus-sasl-plain -dhclient -dhcpv6_client -dmraid -dosfstools -dump -ed -eject -fbset -finger -ftp -gpm -hesiod -irda-utils -isdn4k-utils -lftp -lha -logwatch -lrzsz -mailcap -minicom -mtools -mtr -mt-st -nano -nc -netconfig -NetworkManager -ntsysv -pam_smb -parted -pax -pcmcia-cs -pinfo -quota -rdate -rdist -redhat-logos -rmt -rp-pppoe -rsh -sendmail -slang -stunnel -system-config-mouse -system-config-network-tui -system-config-securitylevel-tui -talk -tcsh -up2date -vconfig -wireless-tools -wvdial -xinetd -ypbind -yp-tools

Firefox, sound, flash under CentOS 4.7
by Stephen Harris 20 Mar '09

20 Mar '09

If I run firefox then everything is fine... until I hit a page with flash and sound on it (youtube, some other stuff). Then it sems to lock the sound device and no other programs (eg Pidgin) can make sounds. In previous versions of firefox (firefox 2? Can't remember) I could run it under esddsp and then firefox/Flash played nicely with others. However now firefox just doesn't start up. FWIW, I don't use Gnome or KDE as a window manager; that _shouldn't_ cause any impact. Any ideas? -- rgds Stephen
