Re: Pam Authorization Problem
Hi, thanks for your reply! my goal is to authenticate through ldap and to do some specific authorization checks. for failover i have one account in /etc/passwd in case of a downtime of ldap so that its still possible to login throught local authentication. Further more i have inside of ldap.conf the following: --- # Group to enforce membership of pam_groupdn cn=klever,ou=hosts,dc=xxx,dc=xxx,dc=xxx # Group member attribute pam_member_attribute uniqueMember --- this should do authorization and should only allow to login if the account who is login in also exists in 'cn=klever,ou=hosts,dc=xxx,dc=xxx,dc=xxx' with its full DN inside the uniqueMember attribute. Authentication is already working with AUTH directive inside of /etc/pam.d/sshd. So i want to allow any user to login if in ACCOUNT the check with pam_ldap is true and the user exists also there or if the user exists inside of /etc/passwd. First of all -- be clear on where the user record exists. Identify if 'klever' exists both in LDAP and locally, or in only one. You will drive yourself nuts if you don't keep this straight. I suggest creating local- and directory-only test users when hacking on PAM. this is what i have done. Secondly, understand what checks happen where. With PADL pam_ldap the only way you can tell most of this is to read the code, sadly. In this case, the various access checks happen in pam_sm_acct_mgmt(), which corresponds to 'account' in pam.conf. i dont have much C knowledge so this will be very hard. Because you have specified that the failure of pam_ldap is not fatal to the account stack. The sufficient control means: If this module returns success, then stop stack processing and return success to the application. Otherwise continue processing. Since the access check constitutes a failure and sufficient effectively ignores failures, you've made the access checks useless. :) You probably want to set it to required, but there are a couple of options to mask certain failure modes you may need to set so that you get the proper fallback to local logins. Those options are ignore_unknown_user ignore_authinfo_unavail Add thesse to the end of the 'account ..pam_ldap' line. If you don't want to set the options you can move it below pam_unix, but the control must still be required for the appropriate action to be taken. Remember, you need to treat ldap failing as fatal to the stack if you want the access controls to have any effect. PAM is horrifically compilicated. I just spent 2 months implementing it at my employer and getting the cases right is a bitch. In fact, its still wrong there. :( I have all combinations tried in the ACCOUNT section but without the special attributes you have written about 'ignore_unknown_user/ignore_authinfo_unavail'. i will test them, maybe they are the only missing and required things to get this working. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-stable To unsubscribe, send any mail to [EMAIL PROTECTED]

On Wed, 17 Nov 2004, Emanuel Strobl wrote: I really love 5.3 in many ways but here're some unbelievable transfer rates, after I went out and bought a pair of Intel GigaBit Ethernet Cards to solve my performance problem (*laugh*): I think the first thing you want to do is to try and determine whether the problem is a link layer problem, network layer problem, or application (file sharing) layer problem. Here's where I'd start looking: (1) I'd first off check that there wasn't a serious interrupt problem on the box, which is often triggered by ACPI problems. Get the box to be as idle as possible, and then use vmstat -i or stat -vmstat to see if anything is spewing interrupts. (2) Confirm that your hardware is capable of the desired rates: typically this involves looking at whether you have a decent card (most if_em cards are decent), whether it's 32-bit or 64-bit PCI, and so on. For unidirectional send on 32-bit PCI, be aware that it is not possible to achieve gigabit performance because the PCI bus isn't fast enough, for example. (3) Next, I'd use a tool like netperf (see ports collection) to establish three characteristics: round trip latency from user space to user space (UDP_RR), TCP throughput (TCP_STREAM), and large packet throughput (UDP_STREAM). With decent boxes on 5.3, you should have no trouble at all maxing out a single gig-e with if_em, assuming all is working well hardware wise and there's no software problem specific to your configuration. (4) Note that router latency (and even switch latency) can have a substantial impact on gigabit performance, even with no packet loss, in part due to stuff like ethernet flow control. You may want to put the two boxes back-to-back for testing purposes. (5) Next, I'd measure CPU consumption on the end box -- in particular, use top -S and systat -vmstat 1 to compare the idle condition of the system and the system under load. If you determine there is a link layer or IP layer problem, we can start digging into things like the error statistics in the card, negotiation issues, etc. If not, you want to move up the stack to try and characterize where it is you're hitting the performance issue.

Remember that when using 32bit PCIs you can get transfer about 500Mbit/s. Please run those test with netperf (/usr/ports/benchmarks/netperf) and send results. Be aware, btw, that while netperf is a pretty decent tool, it performs a lot of socket select and timing operations, so isn't always a good measure of maximum capabilities of a system. I.e., it is not unusual to see that a netperf send test will only see send() as one in three or one in four system calls -- as a result, it uses a measurable amount of CPU on things other than sending. In an environment with CPU constraints (slower CPU or faster network), this can impact the performance results substantially. For example, when measuring maximum packet send performance using minimal packet sizes from user space, several of my test boxes are constrained with 64-bit gig-e PCI cards based on CPU. In particular, the combined cost of the additional system calls and operations cuts into available CPU for send. By eliminating the misc. overheads of netperf using netsend, I can improve performance by 20%-30%.

I see precisely this problem on several motherboards, including the Intel Westville. There's some speculation on the source of the problem, but I see related problems in 4.x as well. Either I get them on different interrupts but both fire, or on the same interrupt. FYI, picking the right one depends a bit on your configuration, but generally scheduling multiple ithreads is more expensive than running multiple handlers in the same ithread, so I think it's generally preferable to run with them on the same interrupt. Especially if nothing on the same interrupt is acquiring Giant. Acquiring and dropping Giant uncontended is cheaper than context switching, however. Finally, my question. What would you recommend: 1) Run with ACPI disabled and debug.mpsafenet=1 and hope that the mix of giant-safe and giant-locked (em and ahc) doesn't trigger any bugs. This is what I currently do. This shouldn't cause bugs; the ithread handler is smart and will acquire Giant around the ahc code. That will also make it slower due to the extra mutex operations, however. 2) Run with ACPI disabled and debug.mpsafenet=0 and accept lower network performance (it is a high-traffic server, so I'm not sure this is a valid option). 3) Run with ACPI enabled and debug.mpsafenet=1 and accept that em0 interrupts leak to the atapci1+ ithread. This I have done in the past. I think you want to run the ahc stuff, unfortunately. The good news is that the higher the load, the more interrupt mitigation/coalescing will kick in for if_em, so the fewer you'll see. Under load, usually my boxes hang out at 4k-6k interrupts/sec for if_em and don't go much above that.

In Both OS-Versions all the Binaries and the Kernel are compiled on the Client. For RELENG_4 CPUTYPE=i586, RELENG_5 CPUTYPE is overwritten in /etc/make.conf as k6-2. Both kernels are GENERIC except the following Options: cpu i586 #only options HZ=2000 options DEVICE_POLLING The Serverside was constant RELENG_4 with same options. On the Server i has pure DISK I/o-Rates from ~20 MB for wirte and ~30MB for read, so that these not could be the bottleneck. The only bottleneck in the system are the capability of max working interrupts and physically the Network. The Boxes are connectet with daetwyler cat. 5e through an 100MBit exclusive switch that would only be used from these two boxes. In all the Tests i have made only a Push from Client to server, while i have seen that the Server is not the Problem. I have alwas used the same Data to transfer (gziped dump -0 from my systems ca 5.3G) All the tests are made with only one of the described networkadapters on the same Time, the problems seems not to be on the driver side.Maybe?

Re[2]: serious networking (em) performance (ggate and NFS) problem
Hi list,
if you suppose your computer has sufficient performance, please try to
disable or adjust parameters of Interrupt Moderation of em.
In my router(Xeon 2.4GHz and on-board two em interfaces) case, it
improves a router's packet forwarding performance. I think the
interrupt delay by Interrupt Moderation caused NIF's input buffer
overflow or output buffer underrun in this case.
In order to disable Interrupt Moderation, modify src/sys/dev/em/if_em.c
like the following patch and set hw.em.{rx,tx}_{,abs_}int_delay zero by
sysctl.
