Trouble with Marconi ASX-200BX
by Bjoern 21 Sep '07

21 Sep '07

Hi, sorry for a little offtopic. But i don´t knew a better place for hopefully find help. We had a little trouble when trying to configure a "new" Marconi Fore ASX-200BX ATM Switch with an running config from another Marconi ASX-200BX. Some of the config commands, seemed not to be known by the newer Foreos 7.1 on the "new". we tried to do downgrade the Foreos on the "new" Marconi Fore ASX-200BX ATM Switch. Installed was Foreos7.1 on a Pentium based SCP (SCP-ASXp5), careless we decided to delete the whole files and wanted to copy the Foreos7.0 files from another System. We backuped the Files to a tftp server, and then we deleted the folders :( No we have the Problem, that we could not create a folder LD7.0 to copy the files from the other System. And we can´t go back with the saved files, because we was to fast to delete the LD7.1 folder :( We have access to Webfrontend and console. But i´m afraid that the SCP is electronic trash if i try to boot now. I think there are 2 possible solutions to solve our Problem: 1. someone could tell us, how to create a folder and we copy the saved files back to the flash Looking back and thinking about what we have tried, and realization how naive we have acted, in my eyes the best way. 2. We make a "system uprade" and this upgrade will recreate the files. Our Problem with the second solution is, that we can´t find a download link for a System upgrade file, like discriped in the manual. We tried to get an public account for the Software http://tactics.marconi.com/services/index.cgi?loadPage=software/software.cg… But we did not get an answer on our request since more then 2 days. Could anyone help us ? Or did we create electronic trash? thanks Bjoern

Question on Loosely Synchronized Router Clocks
by Xin Liu 20 Sep '07

20 Sep '07

Dear Nanogers, We are a bunch of academic researchers interested in Internet security. We notice that some research papers require that BGP router clocks be globally synchronized to a 5-minute granularity. If a router's clock is off by more than 5 minutes, it cannot forward packets, but there's no other side effect. From an operational point of view, do you think it is a practical requirement? If not, what are the potential problems that prevent router clocks from being loosely synchronized? If you consider 5-minute too small, what do you consider as a practical clock skew requirement for BGP routers on the Internet? We'd appreciate your input very much. It will help us understand what's practical and what's not in our work. Please reply to us directly. Thanks, Xin Liu

a respected researcher (with a grad student) i trust wants to > obtain trouble ticket logs from different networks to understand the > nature of failures in ISP networks. we hope that this analysis will > help us develop troubleshooting techniques. they have some data already from abiline and a large euro telco. further, > we can sign NDAs if needed and we'll anonymize the data before > publishing. they realize that such data are extremely sensitive. and also know that they are buried in kinky databases etc. but one has to try. ( and let's try not to rat-hole on nanog about why this is good, insane, will cause starvation in iowa, might end global warming, ... :) if you think you might be willing to help, drop me a note and i will introduce you. thanks. randy

Hi, since when does ftp://ftp.arin.net/info/asn.txt contain dotted AS numbers? Where is the new formatting documented, asn.h ? It just broke a scriptology we use to generate AS lookups for 'offline' customers (please don't ask :) ). $ head -2 asn.txt [asn.txt] 2007-09-19 02:45:00Z $ tail -7 asn.txt [reformatted some whitespace here] 44032-64511 IANA-RSVD IANA-IP-ARIN (Abuse) 64512-65535 IANA-RSVD2 IANA-IP-ARIN (Abuse) 6.0 B6 WM110-ARIN (Tech) 6.1 ASN4-TELUS AAT-ARIN (Abuse), FTS1-ARIN (Tech), TBOTP-ARIN (Tech) 6.3 H6 KML9-ARIN (Tech) 6.5 ISC-32AS ISCAT-ARIN (Abuse), JDA87-ARIN (Tech) 6.6 BLUEFIN-TRADING HOSTM912-ARIN (Abuse) "Your search - AS number 6.5 ISC32-AS - did not match any documents.

RH0 and Enterprise Input
by Azinger, Marla 20 Sep '07

Nanogers- Specifically Enterprise nogers. Not sure if you are aware of this IETF draft on RH0. Its in last call. So if you want to voice your opinion on whether you feel everyone should stop the traffic "that has RH0 headers" from moving on or just ignore it and let it on by, you will need to make your voice heard now. For the most part everyone is ok with this draft because it doesnt effect them and it helps address a security issue. I havnt heard a large voice from the Enterprise arena who might actually need the traffic to be passed on and not stopped. Thus, my posting this on nanog. -Cheers!
