Policy of Dial-up session processing
by Joe Shen 11 May '07

11 May '07

hi, Maybe this is out-of-topic ,but I can't find any place where could find answer for this question. If this is intrusive, just ingore it please. my question is : how does ISP do with DSL dial-up sessions which pass the accouting period time. E.g. If a customer subscribe DSL service at 15USD/month for 150hours. If the subscriber used 145hours by 30th May. He get online at 21:00 on 31th, and get offline at 5:00 on June 2th. The radius server could only export the customer's session when he get offline. So, problem comes to accouting system which was designed to calculate customer usage on first day of each month. The cut-off line of each month usage is set to 00:00 on first day of each month. Someone says , ISP should force those session closed at 00:00 on first day of each month, because they must ensure dial-up session of last month sould not be accouted in next month. Is this true ? thanks in advance. Joe __________________________________ Yahoo! Movies - Search movie info and celeb profiles and photos. http://sg.movies.yahoo.com/

Cisco IOS devices that do not have the FTP server feature enabled are not affected. Cisco IOS XR is not affected. No other Cisco devices are known to be affected. Details ======= Multiple vulnerabilities were discovered in the operation of the IOS FTP Server feature. They are documented as Cisco bug IDs: * CSCek55259 - Improper authorization checking in IOS FTP server * CSCse29244 - IOS reload when transferring files via FTP Due to the above issues with the IOS FTP server, the feature is being removed. Cisco is considering adding more fully-featured and secure FTP server functionality at a later date. The IOS FTP Server feature removal is addressed with Cisco bug ID CSCsg16908. Vulnerability Scoring Details ============================= Cisco is providing scores for the vulnerabilities in this advisory based on the Common Vulnerability Scoring System (CVSS). Cisco will provide a base and temporal score. Customers can then compute environmental scores to assist in determining the impact of the vulnerability in individual networks. Cisco PSIRT will set the bias in all cases to normal. Customers are encouraged to apply the bias parameter when determining the environmental impact of a particular vulnerability. CVSS is a standards based scoring method that conveys vulnerability severity and helps determine urgency and priority of response. Cisco has provided an FAQ to answer additional questions regarding CVSS at http://www.cisco.com/web/about/security/intelligence/cvss-qandas.html Cisco has also provided a CVSS calculator to help compute the environmental impact for individual networks at http://intellishield.cisco.com/security/alertmanager/cvss Cisco Bug IDs: CSCek55259 - Improper authorization checking in IOS FTP server CVSS Base Score: 10.0 Access Vector: Remote Access Complexity: Low Authentication: Not Required Confidentiality Impact: Complete Integrity Impact: Complete Availability Impact: Complete Impact Bias: Normal CVSS Temporal Score: 8.3 Exploitability: Functional Remediation Level: Official-Fix Report Confidence: Confirmed CSCse29244 - IOS reload when transferring files via FTP CVSS Base Score: 2.0 Access Vector: Remote Access Complexity: Low Authentication: Required Confidentiality Impact: None Integrity Impact: None Availability Impact: Complete Impact Bias: Normal CVSS Temporal Score: 1.7 Exploitability: Functional Remediation Level: Official-Fix Report Confidence: Confirmed Impact ====== Successful exploitation of these vulnerabilities may result in unauthorized users accessing the filesystem on the IOS device, a device restart, or remote code execution. Unauthorized users could retrieve or write the device's startup-config from the filesystem, which may contain information that could enable privilege escalation. Repeated exploitation of the vulnerabilities could lead to an extended Denial of Service (DoS). Software Version and Fixes ========================== When considering software upgrades, also consult http://www.cisco.com/go/psirt and any subsequent advisories to determine exposure and a complete upgrade solution. In all cases, customers should exercise caution to be certain the devices to be upgraded contain sufficient memory and that current hardware and software configurations will continue to be supported properly by the new release. If the information is not clear, contact the Cisco Technical Assistance Center ("TAC") or your contracted maintenance provider for assistance. Each row of the Cisco IOS software table (below) describes a release train. If a given release train is vulnerable, then the earliest possible releases that contain the fix (the "First Fixed Release") and the anticipated date of availability for each are listed in the "Rebuild" and "Maintenance" columns. A device running a release in the given train that is earlier than the release in a specific column (less than the First Fixed Release) is known to be vulnerable. The release should be upgraded at least to the indicated release or a later version (greater than or equal to the First Fixed Release label). Software releases that are not listed in the below table are not affected.

One such method is Secure Copy (SCP). SCP is supported on Cisco IOS images that support strong cryptography. More information on the SCP feature can be found at the following url: http://www.cisco.com/en/US/products/s6350/products_configuration_guide_chap… Another alternative is using the Trivial File Transfer Protocol (TFTP) server in IOS. Information on configuring the TFTP server can be found here: http://www.cisco.com/en/US/products/sw/iosswrel/ps1835/products_configurati… If disabling the IOS FTP Server is not feasible, customers may limit FTP access to the device via one of several mechanisms detailed below. Infrastructure ACLs (iACL) +------------------------- Although it is often difficult to block traffic transiting your network, it is possible to identify traffic which should never be allowed to target your infrastructure devices and block that traffic at the border of your network. Infrastructure ACLs are considered a network security best practice and should be considered as a long-term addition to good network security as well as a workaround for this specific vulnerability. The ACL example shown below should be included as part of the deployed infrastructure access-list which will protect all devices with IP addresses in the infrastructure IP address range. A sample access list for devices running Cisco IOS is below: !--- Permit FTP services from trusted hosts destined !--- to infrastructure addresses. access-list 150 permit tcp TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK eq 21 access-list 150 permit tcp TRUSTED_HOSTS MASK INFRASTRUCTURE_ADDRESSES MASK eq 20 !--- Deny FTP packets from all other sources destined to infrastructure addresses. access-list 150 deny tcp any INFRASTRUCTURE_ADDRESSES MASK eq 21 access-list 150 deny tcp any INFRASTRUCTURE_ADDRESSES MASK eq 20 !--- Permit all other traffic to transit the device. access-list 150 permit IP any any interface serial 2/0 ip access-group 150 in The white paper entitled "Protecting Your Core: Infrastructure Protection Access Control Lists" presents guidelines and recommended deployment techniques for infrastructure protection access lists. This white paper can be obtained here: http://www.cisco.com/warp/public/707/iacl.html Receive ACLs (rACL) +------------------ For distributed platforms, Receive ACLs may be an option starting in Cisco IOS Software Versions 12.0(21)S2 for the 12000 (GSR), 12.0(24)S for the 7500, and 12.0(31)S for the 10720. The Receive ACL protects the device from harmful traffic before the traffic can impact the route processor. Receive ACLs are designed to only protect the device on which it is configured. On the 12000, transit traffic is never affected by a receive ACL. Because of this, the destination IP address "any" used in the example ACL entries below only refer to the router's own physical or virtual IP addresses. On the 7500 and 10720, transit traffic with IP options set will be subject to the Receive ACL and permitted or denied accordingly. Receive ACLs are considered a network security best practice, and should be considered as a long-term addition to good network security, as well as a workaround for this specific vulnerability. The white paper entitled "GSR: Receive Access Control Lists" will help you identify and allow legitimate traffic to your device and deny all unwanted packets: http://www.cisco.com/warp/public/707/racl.html. The following is the receive path ACL written to permit this type of traffic from trusted hosts: !--- Permit FTP from trusted hosts allowed to the RP. access-list 151 permit tcp TRUSTED_ADDRESSES MASK any eq 21 access-list 151 permit tcp TRUSTED_ADDRESSES MASK any eq 20 !--- Deny FTP from all other sources to the RP. access-list 151 deny tcp any any eq 21 access-list 151 deny tcp any any eq 20 !--- Permit all other traffic to the RP. !--- according to security policy and configurations. access-list 151 permit ip any any !--- Apply this access list to the 'receive' path. ip receive access-list 151 Control Plane Policing (CoPP) +---------------------------- The Control Plane Policing (CoPP) feature may be used to mitigate these vulnerabilities. In the following example, only FTP traffic from trusted hosts and with 'receive' destination IP addresses is permitted to reach the route processor (RP). It should be noted that dropping traffic from unknown or untrusted IP addresses may affect hosts with dynamically assigned IP addresses from connecting to the Cisco IOS device. access-list 152 deny tcp TRUSTED_ADDRESSES MASK any eq 21 access-list 152 deny tcp TRUSTED_ADDRESSES MASK any eq 20 access-list 152 permit tcp any any eq 20 access-list 152 permit tcp any any eq 21 access-list 152 deny ip any any ! class-map match-all COPP-KNOWN-UNDESIRABLE match access-group 152 ! ! policy-map COPP-INPUT-POLICY class COPP-KNOWN-UNDESIRABLE drop ! control-plane service-policy input COPP-INPUT-POLICY In the above CoPP example, the ACL entries that match the exploit packets with the "permit" action result in these packets being discarded by the policy-map "drop" function, while packets that match the "deny" action are not affected by the policy-map drop function. CoPP is available in Cisco IOS release trains 12.0S, 12.2SX, 12.2S, 12.3T, 12.4, and 12.4T. Additional information on the configuration and use of the CoPP feature can be found at the following URL: http://www.cisco.com/en/US/products/ps6642/products_white_paper0900aecd804f… Obtaining Fixed Software ======================== Cisco will make free software available to address this vulnerability for affected customers. This advisory will be updated as fixed software becomes available. Prior to deploying software, customers should consult their maintenance provider or check the software for feature set compatibility and known issues specific to their environment.

Omaha is right in the middle of the US and it seems to be a point on most carriers' national backbone maps. There has to be some type of carrier hotel there somehere, but I can't seem to find it. Can anyone provide insight on the 60 Hudson or One Wilshire or 111 8th or Westin of Omaha?

F/OSS SNMP tools (was Re: Cacti 0.8.6j Released)
by Kevin Blackham 09 May '07

09 May '07

You only need to worry about vendor MIBs if you're trying to query/monitor something vendor-specific. Standard stuff like ifInOctets and ifDescr are included in everything. I like to either read through MIBs by hand, or load em in a MIB browser (like mbrowse or use vendor C's snmp explorer tool) to search/dig into a table/value that interests me, then snmpwalk a base OID to find instances and enter the pattern directly into whatever collector tool I'm using that week. If you're trying to use vendor MIBs, you also have to deal with dependencies and conflicts, so prepare for some hair-pulling hell. I'm still on the hunt for a decent F/OSS trap receiver that will allow me to just load up MIBs, and have some simple config/UI method for selecting trigger actions/notifications, maybe some filtering and unknown-trap handling etc. Trying to snag traps with snmptrapd and parsing text output is uncooperative. Inconsistent formatting of key/value etc. On 5/8/07, Matt Palmer <mpalmer(a)hezmatt.org> wrote: > > > [If people think this is off-topic, please let me know and I'll take it to > private mail with Travis.] > > On Tue, May 08, 2007 at 07:32:18PM -0500, Travis H. wrote: > > Hey folks, I am following up to an ancient email because I'm curious > > if anyone has some SNMP-related resources.

RE: Google wants to be your Internet

> We also see this with extranet/supply-chain-type connectivity > between large companies who have overlapping address space, > and I'm afraid it's only going to become more common as more > of these types of relationships are established. Fortunately, IP addresses are not intended for use on the Internet. Rather, they are intended for use with Internet Protocol (IP) implementations. That's why the RIRs, in alignment with RFC 2050, section 3(a), do give out IP address allocations to organizations who are connected to extranet-type networks. If you read RFC 1918, section 2, category 3, you will see that this is consistent. So if the power companies want to assign a unique network address to all power meters then there is no good reason to stop them. After all, it is consistent with the goals of the original IP designers to address every light switch and toaster. Just remember, IP addresses are *NOT* Internet addresses. They are Internet Protocol addresses. Connection to the Internet and public announcement of prefixes are totally irrelevant. --Michael Dillon
