How to have open more than 65k concurrent connections?
by johndole＠hush.ai 14 Oct '10

14 Oct '10

Hi, I am somewhat new to networking. I have interest in running a Bittorrent tracker. I ran one for a bit, and my one Linux box running Opentracker gets overloaded. My connection is good, and most of it isn't being used. Just a lot of people connect, and use up all the 65k "free connections". I tried messing with the sysctls, but it didn't help too much (and just degraded the connection quality for everyone). It is not a malicious attack either as there is only a few connections per IP and they are sending proper Bittorrent tracker requests... So what can I do? How can I have have open more than 65k concurrent connections on standard GNU/Linux? Thanks for any ideas and suggestions. -John

I am having an email issue with yahoo's email blacklists and their auto-responses have been less than helpful.

Using crypto auth for detecting corrupted IGP packets?
by Manav Bhatia 13 Oct '10

13 Oct '10

Hi, I believe, based on what i have heard, that some operators turn on cryptographic authentication because the internet checksum that OSPF, etc use for packet sanity is quite weak and offers trifle little protection against lot of known errors like: - re-ordering of 2-byte aligned words - various bit flips that keep the 1s complement sum the same (e.g. 0x0000 to 0xffff and vice versa) So a corrupted packet could still pass the ethernet CRC checks and IP and OSPF checksums. Or it could be valid till the ethernet CRC check is done and gets corrupted after that (PCI transmission errors, DMA errors, memory issues, line card corruption and last but not the least, CRCs and internet checksums could miss wire-corrupted packets) Currently an operator can do the following: - Use the poor internet checksum OR - Turn on cryptographic authentication in the routing protocols to catch all such bit errors which could be caused by line card corruption, etc. One can go through http://portal.acm.org/citation.cfm?id=294357.294364 to understand the issues with the internet checksums. I would be interested in knowing if operators use the cryptographic authentication for detecting the errors that i just described above. You could send me a mail offline and i will consolidate the responses and send a summary on the list in a few days time. Cheers, Manav
