Red Hat and Broken IPMasquerading 16

The-Pheon asks "Ok. I've read the FAQs, scoured the Linux newsgroups searching for information about ipmasqadm and I still can't get simple port forwarding to work on RedHat6. Any suggestions are greatly appreciated. The scenario: Standard Red Hat 6.0, Kernel 2.2.12, and ipchains-1.3.8. External is ip_aliased with a legal dns addresses, Internal is a single reserved address and network, IP masquerading is configured and working for intenal -> external connections. This seems like it should be simple. To forward a simple telnet I use: /sbin/modprobe ip_masq_portfw; /usr/sbin/ipmasqadm portfw -a -P tcp -L x.x.x.x 23 -R 192.168.1.12 23 The result: A telnet sessions to x.x.x.x (from a completely outside source) just hangs. Closer investigation shows that port forward is working -- sort of." More details are available if you hit the link.

Is there an Uptime Limit? 33

Juniks[for dumminger asks: "O'Reilly's Linux Device Drivers states that: 'When the timer interrupt occurs, the jiffies values is incremented. jiffies is thus number of clock ticks since the operating system was booted; it is decleared in "linux/sched.h" as unsigned long volatile, and it will overflow in one and a third year of continuous operation.' So, will I lose my beloved uptime? I am almost there, and all my dignity will go down the drain if this is true. And not to mention my reputaition at work..." I might be mistaken, but I thought Linux took a time_t value during boot as reported by the RTC and used that for uptime computations. Can someone clarify?

How do Linux Threads Compare to NT Threads? 6

BurnMage asks: "I run a small network at a company that does heavy web and graphic work, as well as digital video production. The DV stuff is absolutely wonderful, cutting edge really nice hardware that costs thousands of dollars... and is only supported on the Windows platform. My personal experience with the machines has really been a constant nightmare until recently; we have gotten things running relatively smoothly. We use the DVRex and RexFX from Canopus, beautiful stuff and great tech support... but a few small messages asking why not port to Linux had a couple people muttering that threads in Linux 'aren't properly implemented'. I have also heard the same about NT. What's the story? I want a clear answer to post on their site."

Linux as an ISDN Based Remote Access Server? 14

Richard Becke asks: " I am planning to set up a Linux box as an ISDN-based dialin server for my company network. I have not been able to find any information about using multiple ISDN cards with Linux. We need to serve at least 6 simultaneous connections. Any ideas or tips would be most welcome. The question can be rephrased like this: How do i set up a Linux-based ISP solution?"

2.2.1x Kernel Building Problems 25

rips asks: "I've been a moderately skilled Linux user for several years now but my problem solving skills on this one have got me stumped. I have compiled many kernels before but when compiling a recent kernel (2.2.11 or 2.2.12) the compilation will run without a hitch, lilo (v20) will accept the changes but after a reboot the system will crash at: 'Uncompressing Linux... Ok'. I have tried compiling the 2.2.12 kernel on 3 different machines with 2 different distributions (RedHat 6.0 and Slackware 3.2.0) and for different target processors and kernel options but nothing seems to work. I've even tried running off a boot disk incase it was LILO but to no avail. This has really got me stumped. Has anyone else figured out the cause/solution to this?"

SMBclient and Local Access Transfers... 8

maan asks: "I recently started using smbclient under Linux. I know that many test results have showed that Samba as a server gives more throughput than an NT server. However, I have found that smbclient is much slower with than Windows when accessing the localhost. Anyone knows if the Samba client needs more work?" That's rather odd. Can someone verify this behavior? Does anyone have any possible explanations?

They explain the object of the test, how many attempts they got, the structure of the attempts and the way someone finally got in.

Linux Databases with Huge Tables? 220

Eugene writes "I am working on a project to create an expansive network monitoring and all encompassing database solution. With archival and ageing of all data we are looking at a database that grows by 40Gb a year, with some tables being well over the 2Gb file limit in Linux/x86. We have narrowed ourselves down to Oracle 8i (for it's stalwart referencial integrity checking, and PL/SQL for tracing across aged route information) and PostgreSQL (for it's object polymorphism and CIDR data types for IP addresses). We are concerned with the robustness of Postgres compared to "grown up" Oracle, as well as file size limitations. Can anyone give us any advice on these issues? "

$200 Linux PCs 106

Gekko and Webslacker were the first of many to tell us about the stir over at ZDNet, which is reporting on the arrival of sub $200 PCs due Q1 2000. These new desktops from Taiwan's Tatung come in eye-catching candy colors a la Apple's iMac. Tatung has opted for Rise and Cyrix K6 chips instead of Intel Pentiums, and a CD-ROM drive is an option. One wonders with the increase in the cost of DRAM how this will impact the price?
